**D.**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; RISK FACTORS

We are subject to various risks and uncertainties resulting from changing competitive, economic, political and social conditions that could harm our business, results of operations or financial condition. The risks described below could adversely affect our business, consolidated financial position, results of operations or cash flows. These risks are not the only ones we face. Other risks that we do not presently know about or that we presently believe are not material could also adversely affect us.

#### Risks Relating to our Business and the Steel Industry

#### Demand for steel is cyclical and a reduction in prevailing world prices for steel could adversely affect the Company's results of operations.
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 could cause write-downs of its inventories. In addition, the demand for steel products, and hence the financial condition and results of operations 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. Slow growth in steel consumption was not accompanied by a corresponding slowdown in capacity expansion over the last few years, resulting in an even greater excess of global steel capacity. Since then, the price has experienced a high volatility. A material decrease in demand for steel or exports by countries not able to consume their production could have a significant adverse effect on the Company's financial condition and results of operations.

***Global crises and subsequent economic slowdowns 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 real estate risk 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 experiencing a gradual recovery, principally in the developing economies. For the last eleven years to 2022, driven by population and GDP growth, global demand for steel has been growing strongly in recent years and is expected to

[**Table of Contents**](#TOC)

continue to increase, especially because of economic expansion in India, ASEAN countries and Africa, even as demand in China gradually declines.

The global economy can negatively impact the consuming markets, affecting the business environment with respect to the following:

● Decrease in international steel prices;

● Slump in international steel trading volumes;

● Crisis in automotive industry and infrastructure sectors; and

● Lack of liquidity in the international market.

If the Company is not able to remain competitive in these shifting markets, our profitability, margins and income may be negatively affected. A decline in this trend could result in a decrease in the Company's shipments and revenues. As a result, the Company's financial condition and results of operations may be adversely affected.

#### Our results and financial condition are affected by global and local market conditions that we do not control and cannot predict
We are subject to the risks arising from adverse changes in domestic and global economic and political conditions. Our industry is cyclical by nature and fluctuates with economic cycles, including the current global economic instability. Recessions and significant disruptions in the global financial markets may affect the Company. Our operations experienced significant disruptions in 2008 and the United States, Europe and other economies went into recession. New challenges include the effects of the United Kingdom's withdrawal from the European Union (BREXIT) and increasing political uncertainty and instability in a number of countries. In 2020, the Pandemic resulted in the temporary closing of several industries, including the steel industry. Measures were taken to contain the virus spread among employees, in accordance with regulations promulgated by local authorities. The effects extended to operations and impacted the Company's results, mainly in April, May and June of that year. There continues to be considerable uncertainty over the long-term effects of the expansionary monetary and fiscal policies that have been adopted by the central banks and financial authorities of some of the world's leading economies, including China. These policies may have a negative impact on the global and local economy, and consequently our business, financial condition and results of operations. We cannot predict if the actions taken in the United States, Europe, China and elsewhere in the world to address the adverse effects of the COVID-19 Pandemic will be successful in reducing the duration and impact of the economic instability, inflation and political uncertainty. The risk of trade protection measures in favor of local producers of competing products and the disruption in existing trade agreements or increased trade friction between countries (e.g., the U.S. and China) could have a negative effect on our business and results of operations by restricting the free flow of goods and services across borders and exacerbating global economic conditions. Global economic weakness may prompt banks to limit or deny lending to us or to our customers, which could have a material adverse effect on our liquidity, on our operations and on our ability to carry out our announced capital investment programs and may prompt our customers to slow down or reduce the purchase of our products. In addition COVID-19 has also had significant economic and social impacts. We may experience longer sales cycles, difficulty in collecting sales proceeds and lower prices for our products. Despite the gradual normalization, we cannot provide any assurance that any of these events will not have a material adverse effect on market conditions, the prices of our securities, our ability to obtain financing and our results of operations and financial condition.

***The continuing impact of the Russian invasion of Ukraine, or any widening of the conflict, could have a materially adverse impact on our results of operations and financial condition***

The continuing Russian invasion of Ukraine and any widening of the conflict could have a material adverse effect on the overall macroeconomic environment, which might include demand for steel and iron ore and prices, as well as increasing energy costs. Both the conflict itself and the sanctions imposed (and further sanctions that may be imposed), as well as potential Russian responses to sanctions, have had and could have further destabilizing effects on financial markets and certain commodity markets. The conflict could escalate militarily both regionally and globally. Any substantial escalation would have a material adverse effect on macroeconomic conditions. In addition, sanctions may remain in place beyond the duration of any military conflict and have a long-lasting impact regionally and globally and could adversely impact the Company's results of operations and financial condition.

[**Table of Contents**](#TOC)

***Gerdau faces significant competition in relation to their steel products, including with regard to prices of other domestic and foreign producers, which may adversely affect its profitability and market share.***

The global steel industry is highly competitive with respect to price, quality of products and customer service, as well as in relation to technological advances that allow the reduction of production costs. Brazilian exports of steel products are influenced by several factors, including protectionist policies of other countries, foreign exchange policy of the Brazilian government and growth rate of the world economy. Moreover, continuous advances in material sciences and the resulting technologies facilitate the improvement of products such as plastic, aluminum, ceramics and glass, allowing them to replace steel.

Due to the high initial investment costs, the operation of a steel plant on a continuous basis may encourage mill operators to maintain high production levels, even in periods of low demand, which would increase the pressure on industry profit margins. A competitive pressure that forces the fall in steel prices can also affect the profitability of Gerdau.

The steel industry has historically suffered from excess of production capacity, which has worsened due to a substantial increase in production capacity in emerging countries, particularly China and India and other emerging markets. Despite the fact that the world crude steel production suffered a 10.8% decrease in 2022, this year represents a production decrease in a world with much more production capacity. China is currently the largest global steel producer. In addition, China and certain steel exporting countries have favorable conditions (excess steel capacity, devalued currency or high market prices for steel products in markets outside these countries) which may significantly impact the price of steel in other markets. If Gerdau is unable to remain competitive with China and other steel-producing countries, its financial condition and results of operations may be adversely affected in the future.

***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 the Company operates.***

One significant factor in the global steel market has been China's high steel production capacity, which has been exceeding its domestic consumption needs. This has made China a net exporter of steel products, increasing its importance in different countries of the transoceanic market and consequently pushing down international steel prices. Moreover, China's lower growth rate has resulted in a slower pace of steel consumption in the country, consequently reducing demand for imported raw materials and putting pressure on global commodity prices. Any intensification of these factors could adversely affect the Company's exports, results of operations and financial condition.

#### 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 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 suppliers 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 selling 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. As a result, the Company's financial condition and results of operations may be adversely affected.

#### Increases in iron ore and coal prices, or reductions in market supply, and price increases in other inputs, could adversely affect the Company's operations.
When the prices of 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 hot pig iron at its Ouro Branco, Barão de Cocais and Divinópolis mills located in the state of Minas Gerais.

The Ouro Branco mill is the Company's largest mill in Brazil, and its main metal input for the production of steel is iron ore. This unit represented 55% of the total crude steel output (in volume) of the Brazil Business Segment. A shortage of iron ore in the domestic market may adversely affect the steel producing capacity of the Brazilian units, and an increase in iron ore prices could reduce profit margins.

The Company has iron ore mines in the Brazilian state of Minas Gerais. To mitigate its exposure to the volatility in iron ore prices, the Company invested in expanding the production capacity of these mines.

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 Ouro Branco 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. The coking coal used in this mill is imported from Canada, the United States, Australia, Mozambique, Peru and Colombia.We have entered into long-term contracts with negotiable prices periodically to minimize the risks of shortages. A shortage of coking coal in the international market would adversely affect the steel producing capacity of the Ouro Branco mill. In addition, an increase in prices could reduce profit margins. Another related risk is the currency depreciation to which the Ouro Branco Mill is exposed, since all coking coal consumed by the operation is imported.

Volatility in the supply and prices of these and other raw materials, energy and transportation, could adversely affect the Company's results of operations. We are vulnerable to inflationary cost pressures, especially in relation to the prices of electricity, natural gas and CO2. There were inflationary cost pressures as a consequence of the Russian invasion of Ukraine in 2022, resulting in disruption of markets and supply chains and sanctions impacts.

Such events could adversely affect the Company's financial condition and results of operations.

#### Risks Relating to our Operations

#### The Company's projects are subject to risks that may result in increased costs or delay or prevent their successful implementation.
The Company invested to further increase productivity of its operations. These projects are subject to several risks that may adversely affect the Company's growth prospects and profitability, including the following:

● the Company may encounter delays, availability problems or higher than expected costs in obtaining the necessary equipment, services and materials to build and operate a project;

● the Company's efforts to develop projects according to schedule may be hampered by a lack of infrastructure, including availability of overburden and waste disposal areas as well as reliable power and water supplies;

● the Company may fail to obtain, lose, or experience delays or higher than expected costs in obtaining or renewing the required permits, authorizations, licenses, concessions and/or regulatory approvals to build or continue a project; and

● changes in market conditions, laws or regulations may make a project less profitable than expected or economically or otherwise unfeasible.

Any one or a combination of the factors described above may materially and adversely affect the Company's financial condition and results of operations.

***Unexpected equipment failures may lead to production curtailments or shutdowns.***

Unexpected interruptions in the production capabilities at Gerdau's principal sites and installations would increase production costs, reducing shipments and earnings for the affected period. These interruptions result from: (i) unpredictable/periodic equipment failures, which are essential to the development of the production processes of Gerdau, such as steelmaking equipment, such as its electric arc furnaces, continuous casters, gas-fired reheat furnaces, rolling mills and electrical equipment, including high-output transformers; and/or (ii) unanticipated events such as fires, explosions or violent weather conditions. As a result, Gerdau has experienced and may in the future experience material plant shutdowns or periods of reduced production. Unexpected interruptions in production capabilities would adversely affect Gerdau's productivity and results of operations. Moreover, any interruption in production capability may require Gerdau to make additions to fixed assets to remedy the problem, which would reduce the amount of cash available for operations. Gerdau'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 adversely affect the business, results of operations, cash flows and financial condition.

***Failure to obtain the necessary permits and licenses could adversely affect our operations.***

We depend on the issuance of permits and licenses from governmental agencies in order to undertake some of our activities that are considered polluting or potentially polluting. For the purpose of obtaining said licenses, certain investments in conservation

[**Table of Contents**](#TOC)

are required to offset any such impact. The operational licenses require, among other things, that we periodically report our compliance with emissions standards set by environmental agencies. Failure to obtain, renew or comply with our operating licenses may cause delays in our deployment of new activities, increased costs, monetary fines or even suspension of the affected activity, which may materially adversely affect us.

C***limate change may negatively affect our business, financial condition, results of operations and cash flows.***

A significant number of scientists, environmentalists, international organizations, regulators and other commentators sustain that global climate change has contributed, and will continue to contribute, to the increasing unpredictability, frequency and severity of natural disasters (including, but not limited to, hurricanes, droughts, tornadoes, freezes, other storms and fires) in certain parts of the world. As a result, a number of legal and regulatory measures as well as social initiatives have been introduced in numerous countries in an effort to reduce carbon dioxide and other greenhouse gas emissions and combat global climate change. Such reductions in greenhouse gas emissions could result in increased energy, transportation and raw material costs and may require us to make additional investments in facilities and equipment. Although we cannot predict the impact of changing global climate conditions, if any, or of legal, regulatory and social responses to concerns about global climate change, any such occurrences may negatively affect our business, financial condition, results of operations and cash flows.

Laws and regulations seeking to reduce greenhouse gases can be enacted in the future, which could have a significant adverse impact on the operating results, cash flows, and the financial condition of the Company.

One of the possible effects of the increasing requirements related to the reduction of greenhouse gas emissions is the increase in costs, mainly due to the demand to reduce the consumption of fossil fuels and the implementation of new technologies in the production chain.

The Company believes that the operations in the countries where it operates may be affected in the future by federal, state and municipal initiatives related to climate change, intended to deal with the issue of greenhouse gases (GHG).

In Brazil, there are initiatives lead by the Legislative branch of the Brazilian government to establish a carbon market in Brazil, which if approved it will be regulated later by the Executive branch. At state levels, there are demands for accounting for the inventory of greenhouse gases and reporting to regulatory bodies as well as discussions about decarbonization strategies.

In the U.S., future federal and/or state carbon regulation potentially presents impact to our operations. To date, the U.S. Congress has not legislated carbon constraints. In the absence of comprehensive federal carbon legislation, numerous state, regional and federal regulatory initiatives are under development or are becoming effective, thereby creating a disjointed approach to GHG control and potential carbon pricing impacts.

The Inflation Reduction Act, passed by the U.S. Congress in August 2022, contains significant energy security and climate related measures, such as investments in renewable energy production and tax credits aimed at reducing carbon emissions. Agencies are finalizing guidance on labor standards and domestic content requirements. The expansion and extension of solar tax credits is expected to have a meaningful impact on the solar energy sector, a significant and growing market for our North America segment.

In Canada, the three Gerdau mills are required to report facility-level greenhouse gas emissions and production data with verification by a third-party. The Canadian Federal Greenhouse Gas Pollution Pricing Act has been in effect since 2019, setting a carbon price at $50/tCO2e for 2022. An annual facility emissions limit is determined by multiplying production by an emissions intensity performance standard(s). If emissions are above the annual emissions limit, the facility must pay an excess emission charge to Government and/or purchase emission credits. However, if facility emissions are below the limit, emissions credits are awarded to sell or save for future years.

[**Table of Contents**](#TOC)

***The Company's operations are energy-intensive, and energy shortages or higher energy prices could have an adverse effect.***

Crude steel production is an energy-intensive process, especially in melt shops with electric arc furnaces. Electricity represents an important production component at these units, as also does natural gas, although to a lesser extent. Electricity cannot be replaced at Gerdau's mills and power rationing or shortages could adversely affect production at those units. As a result, the Company's financial condition and results of operations may be adversely affected.

***Layoffs in the Company's labor force could generate costs or negatively affect the Company's operations.***

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, the Company could be adversely affected by labor disruptions involving unrelated parties that may provide goods or services to the Company. Strikes and other labor disruptions at any of the Company operations could adversely affect the operation of facilities and the timing of completion and the cost of capital of our projects.

***We could be harmed by a failure or interruption of our information technology systems or automated machinery.***

We rely on our information technology systems and automated machinery to effectively manage our production processes and operate our business. Advanced technology systems and machinery are nonetheless subject to defects, interruptions and breakdowns. Any failure of our information technology systems and automated machinery to perform as we anticipate could disrupt our business and result in production errors, processing inefficiencies and the loss of sales and customers, which in turn could result in decreased revenue, increased overhead costs and excess or out-of-stock inventory levels resulting in a material adverse effect on our business results. Although we have procedures in place to prevent and minimize the impact of a potential failure, including a data back-up system for our management systems, 24/7 monitoring of our servers, and a cybersecurity program that maintains a Corporate Information Security Policy and a Data Privacy Policy in place, there is no assurance that these will work properly or that there will not be an impact on our results of operations or financial condition.

In addition, our information technology systems and automated machinery may be vulnerable to damage or interruption from circumstances beyond our control, including fire, natural disasters, systems failures, viruses, cyber-attacks and other security breaches, including breaches of our production processing systems that could result in damage to our automated machinery, production interruptions or access to our confidential financial, operational or customer data. Any such damage or interruption could have a material adverse effect on our business results, including as a result of our facing significant fines, customer notice obligations or costly litigation, harming our reputation with our customers or requiring us to expend significant time and expense developing, repairing or upgrading our information technology systems and automated machinery.

Further, while we have some backup data-processing systems that could be used in the event of a failure of our primary systems, we do not yet have a disaster recovery plan or a backup data center that covers all of our units. While we endeavor to prepare for failures of our network by providing backup systems and procedures, we cannot guarantee that our current backup systems and procedures will operate satisfactorily in the event of a regional emergency. Any substantial failure of our backup systems to respond effectively or on a timely basis could have a material adverse effect on our business and results of operations.

***We are subject to information technology risks related to breaches of security pertaining to sensitive company, customer, employee and vendor information as well as breaches in the technology used to manage operations and other business processes****.*

Cybersecurity is a significant concern due to the importance of information technology to the successful conduct of our business operations.We have an executive dedicated to leading the Information Security and Data Protection effort as well as an internal team with qualified specialists and analysts to conduct and evaluate the adequacy of the security and data protection controls. Additionally, we also have an incident response service provider to support our team to prevent and respond to cyber incidents.

We rely upon secure information technology systems for data capture, processing, storage and reporting. Despite careful security and controls design, implementation, updating and independent third-party verification, that also includes specific policies, procedures, and specialized software tools for cybersecurity and data protection, our information technology systems, and those of our third-party providers, could become subject to employee error or malfeasance, natural disasters or be susceptible to cyberattacks. Network, system, application, and data breaches could result in operational disruptions or information misappropriation. Access to internal applications required to plan our operations, source materials, manufacture and goods and account for orders could be denied

[**Table of Contents**](#TOC)

or misused. Theft of intellectual property or trade secrets, and inappropriate disclosure of confidential company, employee, customer or vendor information, could stem from such incidents. Any of these operational disruptions and/or misappropriation of information could result in lost sales, business delays, negative publicity and could have a material effect on our business. We also could be required to spend significant financial and other resources to remedy the damage caused by a security breach, including to repair or replace networks and information technology systems, liability for stolen information, increased cybersecurity protection costs, litigation expense and increased insurance premiums.

***Outbreaks of disease and health epidemics could have a negative impact on our business revenues and results of operations.***

In late December 2019 a notice of pneumonia of unknown cause originating from Wuhan, Hubei province of China was reported to the World Health Organization. A new corona virus called COVID-19 virus was identified, with cases soon confirmed in multiple provinces in China, as well as in several other countries. The Chinese government placed Wuhan and multiple other cities in Hubei province under quarantine, with approximately 60 million people affected. Since that time the virus has been identified in virtually every country, and travel to and from China, most Europe, India, the United States and other countries, including Brazil, has been suspended or restricted by certain air carriers and foreign governments. On March 2, 2020, the World Health Organization declared the coronavirus outbreak a "pandemic", which is disease that is widespread around the world with an impact on society. The term has been applied to only a few diseases in history, including the deadly flu of 1918, the H1N1 flu in 2009 and HIV/AIDS. The ongoing COVID-19 pandemic has resulted in extended shutdowns of certain businesses and other activities in many countries, including the United States, Europe and Brazil.

The COVID-19 pandemic continues to impact worldwide economic activity and pose the risk that we or our employees, contractors, suppliers, customers and other business partners may be prevented from conducting certain business activities for an indefinite period of time, including due to shutdowns that may be requested or mandated by governmental authorities or otherwise elected by companies as a preventive measure. In addition, mandated government authority measures or other measures elected by companies as preventative measures may lead to our customers being unable to complete purchases or other activities. COVID-19 may continue to have an adverse effect on trading and our operations and, given the uncertainty around the extent and timing of the potential future spread or mitigation and around the imposition or relaxation of protective measures, we cannot reasonably estimate the impact to our future results of operations, cash flows or financial condition.

The nature of our business is complex and, to keep operating, most of our work cannot be performed remotely. Our focus is on protecting the health of our employees: We encourage them to take two doses of the COVID-19 vaccine to reduce the risk of spreading the virus at our operations, since operational continuity is key to people's jobs, to local communities and to the economies of the countries and regions where we operate.

The COVID-19 pandemic impacted the Company production and delivery of steel, resulting in interruption of production in some steel mills as of the second half of March, 2020. In the Brazil Segment, the electric steel mills resumed production throughout April and the Blast Furnace 2 in Ouro Branco - MG resumed production in July. In the North America Segment, the plants continued to operate normally, with production levels gradually adjusted according to the reduction in demand observed in the industry. Civil construction continued with healthy demand levels. In the Special Steel Segment, in Brazil and in the USA, there were scheduled shutdowns at its different electrical mills and rolling mills, considering the level of existing inventories and the demand requested by each customer. In the South America Segment, operations continue to operate with production levels gradually adjusted to the demand observed in the industry.

The Company is following all COVID-19 pandemic prevention guidelines issued by the competent health agencies in the countries in which it operates. For this reason, the Company has adopted a series of measures to mitigate the risk of transmission in the workplace, such as using home office, creating crisis committees, canceling national and international trips and participation in external events. The Company daily monitors the evolution of the pandemic scenario and the impacts that this situation brings to the routines of employees, their families and, also, to the business.

The extent to which COVID-19 may adversely impact our business depends on future developments, which are highly uncertain and unpredictable, including new variants of the virus, information concerning the severity of the pandemic, the adoption rate of vaccines, and the effectiveness of actions globally to contain or mitigate the effects of the pandemic.

Demand for our steel products is directly linked to overall economic activity within those international markets in which we sell our products. A decline in the level of activity in either the domestic or the international markets within which we operate as a

[**Table of Contents**](#TOC)

consequence of future waves of the COVID-19 pandemic and related measures to contain them could adversely affect to a greater extent than experienced in 2020 and impact both the demand and the price of our products and have a material adverse effect on us.

The deterioration of Brazilian and global economic conditions could, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· further negatively impact global demand for steel, or further lower market prices for our products, which could result in a continued reduction of our sales, operating income and cash flows;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· make it more difficult or costly for us to obtain financing for our operations or investments or to refinance our debt in the future;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· impair the financial condition of some of our customers, suppliers or counterparties, thereby increasing customer bad debts or non-performance by suppliers or counterparties; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· decrease the value of certain of our investments.

**Risks Relating to our Mining Operations**

***Estimates of Gerdau's mineral resources are based on interpretations and assumptions and may differ substantially from the quantities that actually can be extracted.***

Gerdau's mineral resources refer to estimated quantities of iron ore and minerals. There are a number of uncertainties that are inherent to such estimates of resources, including many factors that are beyond our control, such as geological and technological factors. The engineering of reserves involves estimating mineral deposits that have yet to be measured accurately, and the accuracy of any reserve estimates is directly related to the quality of the data available, geological interpretations and judgments and engineering. Moreover, estimates from different engineers may vary. As a result, the volume of mineral resources available that will or may be extracted at commercially feasible rates cannot be guaranteed, which could adversely affect the operating results and financial condition of the Company.

Moreover, in order to determine whether a project should advance to its development stage, Gerdau relies on estimates of the mineralized material occurring on its properties. Since Gerdau may not have conducted a feasibility study demonstrating proven or probable reserves, estimates of mineralized material content are less accurate than if they had been made in accordance with the definition of proven and probable reserves recognized by the SEC. Furthermore, until iron ore is effectively mined and processed, any reserves and grades of mineralization must be considered mere estimates. Such estimates are inaccurate and based on geological interpretation and statistical deduction drawn from analyses of drillings and samples, which may not be reliable. We cannot guarantee that such estimates on mineralized material are accurate and that such mineralized material can be extracted or processed profitably. Therefore, any decision to advance to the development stage is inherently risky. We also cannot guarantee that any minerals recovered in small-scale testing can be replicated in large-scale testing under actual conditions or on a production scale. Any material changes in the estimates of mineralized material will affect the financial feasibility of making a property productive, as well as the return on capital of such property.

***Gerdau does not have any proven or probable mineral reserves, and Gerdau's decision to start industrial production to supply its steelmaking activities and sell the surplus is not based on studies demonstrating the economic recovery of any mineral reserves, and therefore is inherently risky. Any resources employed in exploration or development may not be recovered.***

Gerdau has not established any proven or probable mineral reserve on any of its properties. All exploration activities are based on mineral resources classified as mineralized materials, since they do not comply with the SEC definitions of proven or probable reserves. Gerdau is conducting comprehensive exploration studies to determine, in accordance with SEC definitions, the quantity of mineralized material that could be transformed into proven or probable reserves. Therefore, part of the volume of mineralized materials may never make it to the development or production stage.

To demonstrate the existence of proven or probable reserves, it is necessary to carry out additional exploration activities to prove the existence of sufficient mineralized material, with satisfactory continuity, and to obtain a positive feasibility study demonstrating, with reasonable certainty, that the deposits can be extracted and produced profitably and legally. The absence of proven or probable reserves makes it more probable that the Company's properties cease to be profitable and that the financial

[**Table of Contents**](#TOC)

resources employed for exploration and development are never recovered, which would adversely affect the operating results and financial condition of the Company.

***Drilling and production risks could adversely affect the mining process.***

After the discovery of mineral deposits, it could take several years from the initial drilling phase to the feasibility of production, and during such period the economic feasibility of production could suffer changes. Substantial time and investments are necessary to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· create mineral reserves through drilling;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· establish adequate mining and metallurgical processes to optimize the recovery of the metal contained in the ore;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· obtain environmental and other types of licenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· build mining and processing facilities as well as the necessary infrastructure for greenfield properties; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· obtain ore or extract minerals from the ore.

If a mining project proves to be economically unfeasible when Gerdau reaches the profit-earning stage, we could incur substantial losses and be forced to write off mineral assets. Furthermore, potential changes or complications involving metallurgical or technological processes during a project cycle could cause delays and generate higher-than-expected costs, rendering the project economically unfeasible and adversely affecting the financial condition and operating results of the Company.

***The Company has one mining dam for the disposal of tailings, and any accident or defect that affects the structural integrity of any of its dams could affect its image, operating results, cash flows and financial condition.***

Gerdau has one mining dam for the disposal of tailings in the state of Minas Gerais, the Alemães Dam, which has been in operation since 2011 and is regularly monitored. The data from the monitoring instruments are within the safety limits, with the dam classified as Class B (low risk) in accordance with the National Mining Dam Registry available on the website of the National Mining Agency (ANM). Gerdau adopts rigorous standards for engineering control and environmental supervision and conducts a half-yearly Geotechnical Stability Audit to ensure the stability of the dam. Gerdau has Mining Dam Emergency Action Plans that are filed at the regulatory agencies, as required by applicable law.

The Company also has other structures that are treated as Mining Dams by the ANM: UTM 2 Bays, North Dike of Tailing Pile 01, and North and South Bays of Tailings Pile A. These are structures that receive stormwater runoff and/or effluents from drainage at the Ore Treatment Units to enable the sedimentation of solid waste before the water is returned to the environment.

They also undergo external audits that attest to their geotechnical stability, as well as regular inspections and monitoring.

An accident involving any of these dams could have serious adverse consequences, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Temporary/permanent shutdown of mining activities and consequently the need to buy iron ore to supply mills;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· High expenditures on contingencies and on recovering the regions and people affected;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· High investments to resume operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Payment of fines and damages;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Potential environmental impacts.

Any of these consequences could have a material adverse impact on the Company's operating results, cash flow and financial condition.

[**Table of Contents**](#TOC)

**Financial Risks**

***Any downgrade in the Company's credit ratings could adversely affect the availability of new financing and increase its cost of capital.***

In 2007, the international rating agencies, Fitch Ratings and Standard & Poor's, classified the Company's credit risk as "investment grade", enabling the Company to access more attractive borrowing rates. During reviews in 2022, despite a lower local sovereign credit rating, the Company maintained its investment grade with S&P and Fitch, respectively, with stable outlook and was upgraded to Baa3 from Ba1 rating with Moody's with stable outlook, reflecting the Company's history of conservative capital allocation, combined with the expectation of strong operating performance throughout the year.

The loss of any one or more of Gerdau's investment grade ratings could increase its cost of capital, impair its ability to obtain capital and adversely affect its financial condition and results of operations.

***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, together with a resulting change in rating by the credit rating agencies, could have important consequences, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· It may limit the ability to declare dividends on its shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The Company may be vulnerable in a downturn in general economic conditions; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The Company may be required to adjust the level of funds available for additions to fixed assets.

As a result, the Company's financial condition and results of operations may be adversely affected.

***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 results of operations 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 Segment 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 results of operations. 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*.

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.

The Brazilian real depreciated against the U.S. dollar by 28.9% in 2020 and 7.4% in 2021. In 2022, the Brazilian real appreciated against the U.S. dollar by 5.3%. To date in 2023, the Brazilian real has appreciated by 0.2% by the end of February 2023.

[**Table of Contents**](#TOC)

The Company held debt denominated in foreign currency, mainly U.S. dollars, in an aggregate amount of R$9.6 billion at December 31, 2022, representing 76% of its consolidated gross debt (loans, financings, and debentures). Significant further 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*.* As a result, the Company's financial condition and results of operations may be adversely affected.

Exchange rate instability also may adversely affect the amount of dividends we can distribute to our shareholders, including the holders of our ADSs and the market price of our shares and ADSs.

***Unfavorable outcomes in judicial, administrative and regulatory litigation may negatively affect our results of operations, cash flows and financial condition.***

We are involved in several tax, environmental, civil and labor disputes involving significant monetary claims.

The principal litigations are described more fully in "Legal Proceedings." and in Note 19 to the Consolidated Financial Statements appearing elsewhere in this Annual Report. Among the material matters for which no provision has been established because they are considered as possible contingent liabilities (possibility of any outflow in settlement is possible):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The Company and its subsidiaries Gerdau Aços Longos S.A. and Gerdau Açominas S.A. have lawsuits related to the ICMS (state VAT) which are mostly related to credit rights and rate differences, representing claims that totaled R$559.076.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The Company and certain of its subsidiaries in Brazil are parties to claims related to: (i) Imposto sobre Produtos Industrializados - IPI, substantially related to IPI credit on inputs, whose demands total the updated amount of R$434,095; (ii) PIS and COFINS, substantially related to disallowance of credits on inputs totaling R$1,646,717, (iii) social security contributions in the total of R$139,219 and (iv) other taxes, the updated total amount of which is currently R$732,283.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The Company and its subsidiary Gerdau Aços Longos SA are parties to administrative proceedings related to Withholding Income Tax, levied on interest remitted abroad, linked to export financing formalized through "Prepayment of Exports Agreements "(PPE) or" Advance Export Receipt "(RAE), in the updated amount of R$1,719,027.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The Company is party to administrative proceedings related to goodwill amortization pursuant to articles 7 and 8 of Law 9,532/97, from the basis of calculation of Corporate Income Tax (IRPJ) and Social Contribution on net income (CSLL), resulting from a corporate restructuring started in 2010. The updated total amount of the assessments is R$513,287.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Gerdau S.A. (as successor of Gerdau Aços Especiais S.A.) and its subsidiary Gerdau Internacional Empreendimentos Ltda. are parties to administrative and judicial proceedings relating to IRPJ — Corporate Income Tax and CSLL — Social Contribution Tax, in the current amount of R$1,346,502.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Gerdau S.A. (as successor of Gerdau Aços Especiais S.A.) and its subsidiaries Gerdau Aços Longos S.A. and Gerdau Açominas S.A. are parties to administrative and judicial proceedings relating to the disallowance of goodwill amortization generated in accordance with Article 7 and 8 of Law 9,532/97 — as a result of a corporate restructuring carried out in 2004/2005 — from the tax base of the Corporate Income tax - IRPJ and Social Contribution on Net Income - CSLL. The total updated amount of the proceedings is R$8,734,573.

Brazilian federal authorities and the judiciary branch are investigating certain issues relating to Administrative Board of Tax Appeals (CARF) proceedings, as well as specific political contributions made by the Company, with the purpose of determining whether the Company engaged in any illegal conduct. The Company previously disclosed that, in addition to its interactions with Brazilian authorities, the Company was providing information requested by the U.S. Securities and Exchange Commission ("SEC"). The Company has since been informed by the SEC's staff that it has closed its inquiry and therefore is not seeking any further information from the Company regarding these matters. The Company believes it is not possible at this time to predict the term or outcome of the proceedings in Brazil, and that there currently is not enough information to determine whether a provision for losses is required or any additional disclosures. Neither the Company, its controlling shareholders, board members and executive officers are part of any ongoing criminal publicly disclosed investigations, procedures or legal actions associated to the investigations made by the Brazilian federal authorities and judiciary branch related to CARF proceedings and political contributions made by the Company.

***Default by our clients or not receiving amounts invested with financial institutions could adversely affect the Company's financial condition.***

Gerdau may suffer losses from the default of our clients. Gerdau has a broad base of active clients and, in the case of default of a group of clients, Gerdau may suffer an adverse effect on its business, financial condition, results of operations and cash flows.

This risk arises from the possibility of the Company not receiving amounts arising from sales to customers or investments made with financial institutions, which could also have an adverse effect on the business, financial condition, results of operations and cash flows of Gerdau.

**Regulatory Risks**

***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.***

Gerdau is a steel producer that supplies both the domestic market in Brazil and several 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 Gerdau from selling in these markets. There are no assurances that importing countries will not impose quotas, ad valorem taxes, tariffs or increase import duties, which could adversely affect the Company's financial condition and results of operations.

***Costs related to compliance with environmental regulations could increase if requirements become stricter, which could have a negative effect on the Company's results of operations.***

The Company's industrial units and other activities must comply with a series of federal, state and municipal laws and regulations regarding the environment and the operation of plants in the countries in which they operate. These regulations include procedures relating to control of air emissions, disposal of liquid effluents and the handling, processing, storage, disposal and reuse of solid waste, hazardous or not, as well as other controls necessary for a steel company and with mining activities.

Non-compliance with environmental and regulatory laws and regulations could result in administrative, civil or criminal sanctions and closure orders, in addition to the obligation of repairing damage caused to third parties and the environment, such as clean-up of contamination. If current and future laws become stricter, spending on fixed assets and costs to comply with legislation could increase and negatively affect the Company's financial condition. Moreover, future acquisitions could subject the Company to additional spending and costs in order to comply with environmental legislation. As a result, the Company's financial condition and results of operations may be adversely affected.

***Laws and regulations to reduce greenhouse gases and other atmospheric emissions could be enacted in the near future, with significant, adverse effects on the results of the Company's operations, cash flows and financial condition.***

One of the possible effects of the expansion of greenhouse gas reduction requirements is an increase in costs, mainly resulting from the demand for renewable energy and the implementation of new technologies in the productive chain. On the other hand, demand is expected to grow constantly for recyclable materials such as steel, which, being a product that could be recycled numerous times without losing its properties, results in lower emissions during the lifecycle of the product.

The Company expects operations overseas to be affected by future federal, state and municipal laws related to climate change, seeking to deal with the question of greenhouse gas (GHG) and other atmospheric emissions. Thus, one of the possible effects of this increase in legal requirements could be an increase in energy costs. As a result, the Company's financial condition and results of operations may be adversely affected.

***Our operations expose us to risks and challenges associated with conducting business in compliance with applicable anti-bribery, anti-corruption and antitrust laws and regulations.***

We have operations in Brazil and other countries in South America and North America. We face several risks and challenges inherent in conducting business internationally, where we are subject to a wide range of laws and regulations such as the Brazilian Anti-Corruption Law (Law 12,846/2013), Antitrust Law (Law 12,529/2011), the U.S. Foreign Corrupt Practices Act, or FCPA, and similar anti-bribery, anti-corruption and antitrust laws in other jurisdictions. In recent years, there has been an increased focus on

[**Table of Contents**](#TOC)

corruption in Brazil and also the investigation and enforcement activities of the United States under the FCPA and by other governments under similar laws and regulations. These laws generally prohibit corrupt payments to governmental officials and certain payments, gifts or remunerations to or from clients and suppliers.

Violations of these laws and regulations could result in fines, criminal penalties and/or other sanctions against the Company, our officers or our employees, requirements to impose more stringent compliance programs, and prohibitions on the conduct of the Company's business and our ability to participate in public biddings. The Company may incur expenses and have to recognize provisions and other charges in respect of such matters. In addition, the increased attention focused upon liability issues as a result of investigations, lawsuits and regulatory and environmental proceedings could harm our brand or otherwise impact the growth of our business. The retention and renewal of many of our contracts depends on creating a sense of trust with our customers and any violation of these laws and regulations may irreparably undermine that trust and may lead to termination of such relationships, as well as have a material adverse effect on our financial condition and results of operations. If any of these risks materialize, our reputation, strategy, international expansion efforts and our ability to attract and retain employees could be negatively impacted, and, consequently our business, financial condition and results of operations could be adversely affected.

Brazilian federal authorities and the judiciary branch are investigating certain issues relating to Administrative Board of Tax Appeals (CARF) proceedings, as well as specific political contributions made by the Company, with the purpose of determining whether the Company engaged in any illegal conduct. The Company previously disclosed that, in addition to its interactions with Brazilian authorities, the Company was providing information requested by the U.S. Securities and Exchange Commission ("SEC"). The Company has since been informed by the SEC's staff that it has closed its inquiry and therefore is not seeking any further information from the Company regarding these matters. The Company believes it is not possible at this time to predict the term or outcome of the proceedings in Brazil, and that there currently is not enough information to determine whether a provision for losses is required or any additional disclosures. Neither the Company, its controlling shareholders, board members and executive officers are part of any ongoing criminal publicly disclosed investigations, procedures or legal actions associated to the investigations made by the Brazilian federal authorities and judiciary branch related to CARF proceedings and political contributions made by the Company.

***Our governance and compliance processes may fail to prevent regulatory penalties and reputational harm.***

The Company operates in a global environment and our activities extend over multiple jurisdictions and complex regulatory frameworks, with increased enforcement activities worldwide. Our governance and compliance processes, which include the review of internal controls over financial reporting, may not be able to prevent future breaches of legal, accounting or governance standards. We may be subject to breaches of our Code of Ethics and Conduct, anti-corruption policies and business conduct protocols, as well as to cases of fraudulent behavior, corrupt practices and dishonesty by our employees, contractors and other agents. The Company's failure to comply with applicable laws and other standards could subject it to fines, loss of operating licenses and reputational harm.

**Risks Relating to Brazil**

***Any further downgrading of Brazil's credit rating could adversely affect the price of our shares.***

We can be adversely affected by investors' perceptions of risks related to Brazil's sovereign debt credit rating. Rating agencies regularly evaluate Brazil and its sovereign ratings, which are based on a number of factors including macroeconomic trends, fiscal and budgetary conditions, indebtedness metrics and the perspective of changes in any of these factors.

Brazil's sovereign credit rating is currently rated below investment grade by the three main credit rating agencies. Consequently, the prices of securities issued by Brazilian companies have been negatively affected. A prolongation or worsening of the current Brazilian recession and continued political uncertainty, among other factors, could lead to further ratings downgrades. Any further downgrade of Brazil's sovereign credit ratings could heighten investors' perception of risk and, as a result, adversely affect the price of our shares.

***Brazil continues to experience political instability, which may adversely affect the Company.***

Brazil's political environment has historically influenced, and continues to influence, the performance of the country's economy. Political crises have affected and continue to affect the confidence of investors and the general public, which have historically resulted in economic deceleration and heightened volatility in the securities issued by Brazilian companies.

[**Table of Contents**](#TOC)

In addition, the Brazilian economy remains subject to government policies, which may affect our operations and financial performance. Governmental policies and actions, if unsuccessful or poorly implemented, may affect our operations and financial performance. Uncertainty regarding the implementation by the new administration of promised transformational changes in monetary, fiscal and pension policies, as well as the enactment of corresponding legislation, could contribute to economic instability.

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

If Brazil experiences 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 our business. As a result, the Company's financial condition and results of operations may be adversely affected.

***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 shares.***

The market for securities issued by Brazilian companies is influenced, in some degree, by economic and market conditions in the United States and emerging market countries, especially other Latin American countries. 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 reductions of the investments from investment funds 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 B3, 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 shares, which could make it more difficult for us to access the capital markets and finance our operations in the future on acceptable terms, besides having a material adverse effect on our financial condition and results of operations.

**Risks Related to our Corporate Structure**

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

Subject to the provisions of the Company's bylaws, the controlling shareholder has powers to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· elect a majority of the directors and nominate executive officers, establish the administrative policy and exercise full control of the Company ´ s management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· sell or otherwise transfer the Company ´ s shares; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· approve any action requiring the approval of shareholders representing a majority of the 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, which could adversely affect the financial condition and the results of operations of the Company.

***As a foreign issuer, we have different disclosure and other requirements than U.S. domestic registrants.***

As a foreign issuer, we may be subject to different disclosure and other requirements than domestic U.S. registrants. For example, as a foreign issuer, in the United States, we are not subject to the same disclosure requirements as a domestic U.S. registrant under the United States Securities Exchange Act of 1934, as amended (the Exchange Act), including the requirements to prepare and issue quarterly reports on Form 10-Q or to file current reports on Form 8-K upon the occurrence of specified significant events, the

[**Table of Contents**](#TOC)

proxy rules applicable to domestic U.S. registrants under Section 14 of the Exchange Act or the insider reporting and short-swing profit rules applicable to domestic U.S. registrants under Section 16 of the Exchange Act. In addition, we intend to rely on exemptions from certain U.S. rules which will permit us to follow Brazilian legal requirements rather than certain of the requirements that are applicable to U.S. domestic registrants.

Furthermore, foreign issuers are required to file their annual report on Form 20-F within 120 days after the end of each fiscal year, while U.S. domestic issuers that are accelerated filers are required to file their annual report on Form 10-K within 75 days after the end of each fiscal year. As a result of the above, even though we are required to file reports on Form 6-K disclosing the information which we have made or are required to make public pursuant to Brazilian law, or are required to distribute to shareholders generally, and that is material to us, you may not receive information of the same type or amount that is required to be disclosed to shareholders of a U.S. company.

***As a foreign issuer, we are permitted to, and we do, rely on exemptions from certain NYSE corporate governance standards, including the requirement that a majority of our board of directors consist of independent directors. This may afford less protection to our shareholders.***

The NYSE's rules require listed companies to have, among other things, a majority of their board members be independent and to have independent director oversight of executive compensation, nomination of directors and corporate governance matters. As a foreign issuer and a controlled Company, we are permitted to, and we will, follow home country practice in lieu of the above requirements. Brazilian law, the law of our home country, does not require that a majority of our board consist of independent directors or the implementation of a compensation committee or nominating a corporate governance committee, and our board include fewer, independent directors than would be required if we were subject to the NYSE rules applicable to most U.S. companies. As long as we rely on the foreign issuer exemptions to the NYSE rules, a majority of our board of directors is not required to consist of independent directors, our compensation committee is not required to be comprised entirely of independent directors, and we will not be required to have a nominating and corporate governance committee. Therefore, our board's approach may be different from that of a board with a majority of independent directors, and, as a result, the management team's oversight of the Company may be more limited than if we were subject to the NYSE rules applicable to most U.S. companies.

**Risks Relating to Our Preferred Shares and ADSs**

***If we do not maintain a registration statement and no exemption from the Securities Act registration is available, U.S. Holders of ADSs may be unable to exercise preemptive rights with respect to our preferred shares.***

We may not be able to offer our preferred shares to U.S. holders of ADSs residing in the U.S. pursuant to preemptive rights granted to holders of our preferred shares in connection with any future issuance of our preferred shares unless a registration statement under the Securities Act is effective with respect to such preferred shares and preemptive rights, or an exemption from the registration requirements of the Securities Act is available. We are not obligated to file or maintain a registration statement relating to any preemptive rights offerings with respect to our preferred shares, and we cannot assure you that we will file or maintain any such registration statement. If such a registration statement is not filed and maintained and an exemption from registration does not exist, our depositary will attempt to sell the preemptive rights, and you will be entitled to receive the proceeds of such sale. However, these preemptive rights will expire if the depositary does not sell them, and U.S. holders of ADSs will not realize any value from the granting of such preemptive rights.

***Judgments of Brazilian courts with respect to our preferred shares will be payable only in reais.***

If proceedings are brought in the courts of Brazil seeking to enforce our obligations in respect of the preferred shares, we will not be required to discharge its obligations in a currency other than *reais*. Under Brazilian exchange control limitations, an obligation in Brazil to pay amounts denominated in a currency other than *reais* may only be satisfied in Brazilian currency at the exchange rate, as determined by the Central Bank, in effect on the date the judgment is obtained, and such amounts are then adjusted to reflect exchange rate variations through the effective payment date. The then prevailing exchange rate may not afford non-Brazilian investors with full compensation for any claim arising out of, or related to, our obligations under the preferred shares or the ADSs.

[**Table of Contents**](#TOC)

***If an ADS holder surrenders its ADSs and withdraws preferred shares, it risks losing the ability to remit foreign currency abroad and certain Brazilian tax advantages.***

An ADS holder benefits from the electronic certificate of foreign capital registration obtained by the custodian for our preferred shares underlying the ADSs in Brazil, which permits the custodian to convert dividends and other distributions with respect to the preferred shares into non-Brazilian currency and remit the proceeds abroad. If an ADS holder surrenders its ADSs and withdraws preferred shares, it will be entitled to continue to rely on the custodian's electronic certificate of foreign capital registration for only five business days from the date of withdrawal. Thereafter, upon the disposition of or distributions relating to the preferred shares unless it obtain its own electronic certificate of foreign capital registration or qualifies under Brazilian foreign investment regulations that entitle some foreign investors to buy and sell shares on Brazilian stock exchanges without obtaining separate electronic certificates of foreign capital registration, such former holder of ADSs would not be able to remit abroad non-Brazilian currency. In addition, if an ADS holder does not qualify under the foreign investment regulations, it will generally be subject to less favorable tax treatment of dividends and distributions on, and the proceeds from any sale of, our preferred shares.

If an ADS holder attempts to obtain its own electronic certificate of foreign capital registration, it may incur expenses or suffer delays in the application process, which could delay its ability to receive dividends or distributions relating to our preferred shares or the return of its capital in a timely manner. The depositary's electronic certificate of foreign capital registration may also be adversely affected by future legislative changes.

**A.**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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. Dra. Ruth Cardoso, 8501 – 8<sup>th</sup> floor, São Paulo, SP, Brazil, and the telephone number is +55 (11) 3094 6300. Gerdau's shares are listed on the São Paulo (B3), New York (NYSE) and Madrid (Latibex) stock exchanges.

**Recent 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 and the parent company of Gerdau S.A.

A detailed chronology of the development of the Company from its founding is set forth in our [Annual Report on Form 20-F for the year ended December 31, 2020 (File No. 001-14878)](https://www.sec.gov/Archives/edgar/data/1073404/000110465921053189/tm212083d1_20f.htm), "Item 4A. History and Development of the Company", which is not incorporated by reference into this Annual Report.

Gerdau is Brazil's largest producer of steel, a leading producer of long steel in the Americas and one of the world's leading suppliers of special steel. In Brazil, it also produces flat steel and iron ore for its own use.

Gerdau is the largest recycling company in Latin America and uses scrap as an important input, with 73% of the steel it produces made from the material. Every year, Gerdau transforms 11 million tonnes of scrap into a variety of steel products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**B.** **BUSINESS OVERVIEW** 

**Steel Industry**

The world steel industry is composed of hundreds of steel producing facilities 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 using 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, in 2021 (the most recent year for which information is available), 28.9% of the total crude steel production in the world was through mini mill process and the remaining 70.8% was through the integrated process.

\*Most recent year for which information is available

Over the past 10 years, according to World Steel, total annual crude steel production has grown from 1,540 million tonnes in 2011 to 1,951 million tonnes in 2021, an increase of 26.69%.

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 more than half as much as the rest of the world.

China is rebalancing its economy to move more towards a consumer-driven economy. GDP growth was aligned with the government expectation and despite the injection of credit into the construction and infrastructure sectors, the country showed a reduction in steel consumption for the third year in a row. In 2021, China's share of world steel production was 53% of world total crude steel.

***The Brazilian Steel Industry***

According to World Steel Association, in 2021 Brazil was the world's 9th largest producer of crude steel, with a production of 36.1 million tonnes, a 1.8% share of the world market and 55.8% of the total steel production in South America during the year.

In 2021, the total of Brazilian steel products sales was 33 million tonnes. The breakdown of total sales was 67.5% or 22.3 million tonnes of flat steel products, formed by domestic sales of 12.7 million tonnes and exports of 9.6 million tonnes. The remaining 32.4% or 10.7 million tonnes represented sales of long steel products, which consisted of domestic sales of 9.5 million tonnes and exports of 1.3 million tonnes.

*Domestic demand —* Historically, the Brazilian steel industry has been affected by significant variations in domestic steel demand. Although 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 2021, the Brazilian GDP decreased by 5% and steel consumption increased by 18.5%.

*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 has lagged total supply (total production plus imports).

In 2021, Brazilian steel exports totaled 10.9 million tonnes, representing 33.2% 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 8.0 tonnes in 2021, 7.7 million tonnes in 2020 and 8.5 million tonnes in 2019, representing 73.2% 73.3% and 68.5% of Brazil's total exports of steel products, respectively*.*

*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 from small miners in Brazil is very competitive if compared to the cost of iron ore in China, for example.

In Brazil, most of the scrap metal consumed by steel mills comes from Brazil's southeast and south regions. Mill suppliers deliver scrap metal obtained from obsolete products and industrial scrap directly to the steel mills.

Brazil is a major producer of pig iron. Most of the pig iron used in the steel industry comes from the state of Minas Gerais and the Carajás region, where it is produced by various small and midsized producers. The price of pig iron follows domestic and international markets, with charcoal and iron ore the main components of its cost formation.

***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 and low priced imports. 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.

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 have 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 George W. 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 that 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. On October 31, 2021 the United States and the EU announced an agreement to replace the existing 25 percent tariff on EU steel products under Section 2321 with a tariff-rate quota (TRQ) with a date of effectiveness of January 1, 2022. Under the TRQ arrangement, historically based volumes of EU steel products will enter the U.S. market without the application of Section 232 tariffs subject to certain exceptions. Under the new terms, the European Union will be allowed to ship 3.3 million metric tons of steel annually into the United States duty-free, while any volume above that would be subject to a 25 percent tariff. Products that were granted exclusions from the tariffs this year would also temporarily be exempt. More recently, in mid-March 2022 the United States and Britain announced that the U.S. had agreed to lift tariffs on British steel that is imported in volumes below new quotas established for the imports. Under this agreement Chinese-owned steel companies in Britain must undergo annual audits to ensure that Chinese steel cannot enter the United States tariff-free.

The agreement will also place restrictions on products that are finished in Europe but use steel from China, Russia, South Korea and other countries. To qualify for duty-free treatment, steel products must be entirely made in the European Union.

Global steelmaking production decreased from 2015 to 2018, but the latest available information suggests that capacity increased in 2022 for the fourth year in a row. The Company believes that this trend should continue throughout 2023.

**Company Profile**

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

Gerdau is the leading manufacturer of long steel in North and South America. Gerdau believes it is one of the major global suppliers of special steel for the automotive industry. In Brazil, Gerdau also produces flat steel and iron ore, activities that are expanding Gerdau's product mix and the competitiveness of its operations. In addition, Gerdau believes it is one of Latin America's biggest recyclers and, worldwide, transforms millions of tonnes of scrap metal into steel every year, reinforcing its commitment to sustainable development in the regions where it operates. Gerdau's shares are listed on the New York, São Paulo and Madrid stock exchanges.

Gerdau holds significant market share in the steel industries of almost all countries where it operates and was classified by World Steel Association as the world's 30<sup>th</sup> largest steel producer based on its consolidated crude steel production in 2021, the most recent year for which information is available.

Gerdau operates steel mills that produce steel in blast furnaces and in electric arc furnaces (EAF). In Brazil it operates three integrated steel mills, including its largest mill, Ouro Branco, located in the state of Minas Gerais. Gerdau currently has a total of 32 steel producing facilities globally.

As of December 31, 2022, Gerdau's total consolidated installed annual capacity, excluding investments in joint ventures and associate companies, was approximately 16.7 million tonnes of crude steel and 15.6 million tonnes of rolled steel products. The Company had total consolidated assets of R$73.8 billion, shareholders' equity (including non-controlling interests) of R$46.3 billion, consolidated net sales of R$82.4 billion and a total consolidated net income (including non-controlling interests) of R$11,479.6 million as of and for the year ended December 31, 2022.

Its product mix includes crude steel (slabs, blooms and billets), which is sold to rolling plants; finished products for the construction industry, such as rebar, wire-rods, structural shapes, hot-rolled coils and heavy plates; finished industrial products, such as commercial rolled-steel bars, light profiles and wires; and agricultural products, such as stakes, smooth wire and barbed-wire. Gerdau also produces special steel items using cutting-edge technology.

The Company currently operates 11 steel production units in the United States, Canada and Mexico, and believes it is one of the leading companies in North America in the production of certain long steel products, such as rebar, wire rod, bars and beams.

The Company's operating strategy is based on the acquisition and construction of steel mills located near its clients and the sources of the raw materials needed make steel, such as scrap steel, pig iron and iron ore. Therefore, historically, most of production has been directed to supply the local markets of the regions where the Company operates. However, the Company also exports an excess portion of its production to other countries.

Through its subsidiaries and associate companies, the Company also engages in other activities related to the production and sale of steel products, including reforestation projects; electric power generation projects; production of iron ore and pig iron; 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. Shipments by the Company's Brazilian operations include both domestic and export sales. Most of the shipments by the Company's business segments in North and Latin America (except Brazil) are aimed at their respective local markets.

***Brazil Business Segment***

The Brazil Business Segment 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 forecasted monthly. The Brazil Business Segment 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.

[**Table of Contents**](#TOC)

Crude steel production decreased in 2022, mainly due to the performance of the domestic market. Given the strong demand observed, the Company directed 83,5% of its shipments in the Brazil Business Segment to the domestic market, which is 5% lower than in 2021, while 12% was directed to the international market.

The numbers demonstrate the resilience of the construction sector, in both the retail segment and direct sales to contractors, as well as the industry's gradual recovery.

Gerdau's mineral assets were incorporated to its business through the acquisition of lands and mining rights of Grupo Votorantim, in 2004, encompassing the Miguel Burnier, Várzea do Lopes, and Gongo Soco compounds, located in the iron producing region in the state of Minas Gerais, Brazil. From 2004 to 2019, several geological surveys (drilling and superficial geological mapping) were conducted in order to obtain further information on the acquired resources.

***North America Business Segment***

The North America Business Segment has annual production capacity of 5.4 million tonnes of crude steel and 4.5 million tonnes of finished steel products. It has a vertically integrated network of 8 steel units, scrap recycling facilities and downstream operations. North America Business Segment's products are generally sold to steel service centers, 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.

The mills of this business operation manufacture and commercialize a wide range of steel products, including steel reinforcement bars (rebar), merchant bars, structural shapes, beams and special sections. Some of these products are used by the downstream units to make products with a higher value-add, which consists of railroad spikes, super light beam processing, elevator guide rails and grinding balls.

Sales of finished products to U.S. and Canadian customers are centrally managed by sales office in Tampa, Florida. There is also a sales office in Selkirk, Manitoba for managing sales of special sections and one in Midlothian, Texas for managing sales of structural and merchant bar products. Metallurgical service representatives at the mills provide technical support to the sales group. Sales of the super light beam products are managed by sales representatives located at their respective facilities. Elevator guide rails are generally sold through a bidding process in which employees at Gerdau's facilities work closely with customers to tailor product requirements, shipping schedules and prices.

Steel production in 2022 was slightly lower than in 2021, in line with the level of shipments.

***South America Business Segment***

The South America Business Segment comprises five steel facilities, retail facilities, fab shops (including joint ventures and associate companies) and scrap processing facilities. The entire operation is focused on the respective domestic markets of each country, operating mini mills facilities with annual manufacturing capacity of 890 thousand tonnes of crude steel and 903 thousand tonnes of finished steel products. The countries in the South America Business Segment are Argentina, Peru, and Uruguay. Gerdau also operates in the markets of Colombia and Dominican Republic through joint ventures.

Steel production and shipments in 2022 increased compared to 2021, with the result driven by the good performance of the construction industry.

***Special Steel Business Segment***

The Special Steel Business Segment consists of the operations in Brazil (Charqueadas, Pindamonhangaba and Mogi das Cruzes) and the United States (Forth Smith and Monroe). The segment produces special steels for engineering steel, tool steel and forged bars. To meet the needs of more demanding markets, this segment is constantly developing new products, such as high-resistance steels, clean steel, high temper steel, good machinability steel, among others.

In Brazil, Gerdau special steel units are located in the states of Rio Grande do Sul (Charqueadas) and São Paulo (Pindamonhangaba and Mogi das Cruzes). The special steel units in Brazil have aggregate annual production capacity of 1.4 million

[**Table of Contents**](#TOC)

tonnes of crude steel and 1.8 million tonnes of rolled steel. The operation has over 200 clients that are located primarily in Brazil. However, it also exports products, primarily to South America, North America and Europe.

In North America, the Special Steel Segment is present in the United States, with three units located in Monroe (Michigan) and Forth Smith (Arkansas). The company also operates a downstream unit in Huntington (Indiana). The segment has annual installed production capacity of 1.1 million tonnes of crude steel and 1.1 million tonnes of rolled steel products, with a portfolio of more than 200 clients located mainly in the United States, Canada and Mexico The plants of this business segment have commercial and operational synergies.

Steel production and shipments increased in 2022, mainly due to the good performance of the heavy vehicle sector and of the oil and gas industry. The Special Steel segment was the business segment most affected by the pandemic, mainly due to the shutdowns at many auto assemblers in both Brazil and the United States. During 2021, that segment was affected by the shortage in the supply of semiconductors, which are used in all electronic components installed in vehicles.

***Exports***

In 2022, the international steel market experienced a deep change in supply and demand flows after the outbreak of the conflict between Russia and Ukraine. World steel production fell 4.2% year on year, to 1.878 billion metric tons, with China reducing their steel output for the second year in a row and the absence of Ukraine as an important producer in the Black Sea region. Increase in production costs, with both energy and raw material pressuring European producers, also helped decrease the global production. India and Iran were the outliers, with 5.5% and 8% increases, compared to 2021.

According to Worldsteel Association, China's total output was 1.013 billion tonnes in 2022, which represents a 2.1% decrease, comparing to 2021's 1.033 billion. This retraction follows closely the 3% GDP growth for 2022, below the country's 5% target for the year. The Zero COVID-19 policy, that was in force for most of the year, in conjunction with credit restrictions and high default rates from buyers, impacted the civil construction performance, which is the main driver for steel demand in the country. Low margins also dampened production, with BOF operational rates going from 92% in September to 82% in October.

The changes in the international trade flow of steel present a good picture of the conflict's developments. In 2021, Russia was responsible for 38% of all seaborne slab sold and approximately 25% of billets. With sanctions to Russian companies and individuals imposed by the western world, especially the United States and European Union, a shift was seen on supply and demand flows. Russia focused on Turkey, Asia, Middle East and Northern Africa, while the west developed new suppliers, with Brazil being the primary alternative on slabs and pig iron.

In Europe, steel production was down 10.5% considering the EU countries, 12.5% for the United Kingdom and Turkey and 20.2% for CIS, with Ukraine's production 70% lower compared to 2021. The consequences of the conflict were also felt throughout the continent, with high energy prices, after the restriction on gas supply from Russia, diminishing steel margins, and increasing both interest and inflation rates. These last factors resulted in a decrease in the steel demand and, subsequently, some BOFs being idled in August 2022. The continent produced 266 million tonnes of steel in 2022.

Not only China and Europe saw decreases in production, but North and South America registered 5.5% and 5% contraction, respectively, compared to 2021. By the end of the year, apparent consumption was stable on the lower levels seen in the third quarter. On the opposite side, Iran and India saw increases year on year, after both countries became important suppliers as Europe procured different sources.

[**Table of Contents**](#TOC)

As expected, Gerdau's Brazilian exports in 2022 remained focused in South and Central America, with significant increase in participation year over year. Important market developments and increasing volumes were seen, with flat products being supplied to South America and Europe and long products to Africa.

Gerdau remains focused on serving strategic markets that contribute to the general results of its operation, analyzing the impacts and opportunities arising from the continued volatile international political-economic scenario and consolidating the presence of its entire product portfolio in these markets in 2023.

**Products**

The Company supplies its customers with a wide range of products, including steel products and iron ore:

***Semi-finished products (Billets, Blooms and Slabs)***

The semi-finished 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 to produce wire rod, rebars and merchant bars. They represent an important part of the products from the Ouro Branco 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, and mainly used to produce hot and cold rolled coils, heavy slabs, profiles and heavy plates.

The semi-finished products are produced using continuous casting and, in the case of blooms and billets there is subsequent rolling process.

***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, wire rods, merchant bars, light shapes 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 steel requires advanced manufacturing processes because they have specific physical and metallurgical characteristics for applications with high mechanical demands. This steel is a key product for the automotive industry, as it is used in auto parts, light and heavy vehicles and agricultural machinery. Special steels also serve other significant markets, such as oil and gas, wind energy, machinery and equipment, mining and rail, among others.

[**Table of Contents**](#TOC)

***Flat Products***

The Ouro Branco unit produces cast slabs, which are rolled into flat products, such as hot-rolled steel coils and heavy plates. Gerdau also produces hot-rolled coils, which are sold in the domestic market, and heavy plates, which are sold in the domestic and export markets. The Company, through its distribution channel and direct sales, distributes these hot-rolled coils and heavy plates and resells flat steel products manufactured by other Brazilian steel products, which adds more value through additional processing at flat steel service centers.

***Iron Ore***

Gerdau has three mines producing iron ore, all located in the Brazilian state of Minas Gerais (Várzea do Lopes and Miguel Burnier). The mines produce the following: sinter feed (featuring low content of contaminants and good metallurgical properties, enabling its use as a base material); pellet feed/concentrated (superior quality enabling its use as a chemical balancer in the synthetizing process, while being also adequate for pelletizing, blast furnace quality - low loss by calcination — PPC); hematite fines (small scale production, used as input in Gerdau's furnaces); and granulated (high quality, used chiefly for own consumption at the Ouro Branco Mill).

The following table presents the main products and the contributions to net revenue and net income by Business Segment for the periods shown (consolidated):

**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.

***Semi-integrated Process (Mini mills)***

The Company operates 26 mini mills worldwide. Mini mills are equipped primarily with electric arc furnaces that can melt steel scrap and produce steel product at the required specifications requested by customers. 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·&nbsp;&nbsp;&nbsp;&nbsp; lower capital costs,

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·&nbsp;&nbsp;&nbsp;&nbsp; proximity of production facilities to raw-material sources,

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

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

[**Table of Contents**](#TOC)

***Integrated Process***

Gerdau operates four integrated mills, three of which are located in Brazil and one in Peru. The Ouro Branco Mill is the largest integrated facility operated by the Company. It produces steel from pig iron from the blast furnace and has some of the advantages of a mini mill, since it is located near key suppliers as well as the ports from which Gerdau exports most of its production.

Gerdau's steel manufacturing process at integrated units consists of four basic stages: preparation of raw materials, production of pig iron, production of steel and production of semi-finished steel products (billets, blooms and slabs). In the primary stage of steelmaking, 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 fuel and a reducing agent in this process. Gerdau's blast furnaces have aggregate installed capacity of approximately 3.8 million tonnes of molten pig iron per year.

The pig iron produced is transported by rail to the desulphurization unit to reduce the steel's sulfur content. After the desulphurization process, the low-sulfur pig iron is transformed into steel using LD-type oxygen converters. The LD steelmaking process utilizes molten pig iron and scrap 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 occurring between oxygen and the impurities in the molten pig iron. The LD steelmaking process is currently the most widely used in the world. Some mills further refine the LD converters' output with ladle furnaces and outgassing process.

Liquid steel is then sent to the continuous casting equipment, where it is solidified into billets, blooms or slabs. These products may be sold to clients directly, be transferred to other Gerdau Units for transformation or be used in the production of finished rolled steel products at the integrated units. Gerdau's integrated units in Brazil have rolling mills for rebars, bars and profiles, wire-rod, structural shapes, hot-rolled coils and heavy plates.

**Logistics**

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

Logistics costs are an important component of most steel businesses and represent a significant factor in maintaining competitive prices in the domestic and export markets. The Gerdau 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 monitor and reduce logistic costs, Gerdau uses specific solutions, directed to different types of transportation modes (road, rail, sea and cabotage), terminals, technology and equipment. Gerdau continuously seeks to improve its performance to receive raw materials, and to deliver products to its customers or ports of destination. Accordingly, Gerdau develops and maintain long-term relationships with logistic suppliers 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. This interest assures the availability of this mode to transport raw materials (scrap and pig iron) as well as final products.

Gerdau uses a variety of ports to deliver products from the entire Brazilian coastline. Most exports are shipped from the Praia Mole Private Steel Terminal in Vitoria, Espírito Santo.

Overseas, Gerdau owns a private port terminal in Chimbote (Peru), where the Company has a steel mill, used to deliver inputs, raw material and products for the operation.

**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

[**Table of Contents**](#TOC)

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 and wire rod fabrication facilities.

The Company operates in the flat steel market through its Ouro Branco mill that produces slabs, which are used to roll flat products such as hot and cold rolled steel coils and heavy plates. Gerdau also produces hot-rolled coils, which are sold in the domestic and export markets. The Company distributes these hot-rolled coils and also resells flat steel products manufactured by other Brazilian steel producers to which it adds further value through additional processing at its flat steel service centers.

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 and United States.

***Competitive Position — Brazil***

The Brazilian steel market is very competitive. In the year ended December 31, 2021 (most recent information), ArcelorMittal Brasil and the Company were the two largest Brazilian crude steel producers, according to the Brazilian Steel Institute (IABr - Instituto Aço Brasil).

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 has been facing some competition from long steel products imports, mainly coming from Turkey. 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.

Intense competition exists between the Company and ArcelorMittal in the slab and wire rod markets. With respect to the rebar market, competition in the Brazilian domestic market has increased in recent years due to new competitors like Simec and Companhia Siderurgica Nacional (CSN), which started rebar production.

***Competitive Position — Outside Brazil***

Gerdau's geographic market in North America encompasses primarily the United States and Canada. The Company 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, Jackson, Cartersville and Petersburg mini mills are shipped greater distances, including overseas.

The Company's principal competitors include Commercial Metals Company (CMC), Nucor Corporation, Steel Dynamics Inc. and Cleveland-Cliffs.

In South 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 80% of shipments from Gerdau's South American Operation originate from Argentina and Peru. In this market, the main barriers faced by Gerdau sales are freight and transportation costs and the availability of imports. The main products sold in the South American market are the construction, mechanic, agriculture and mining markets.

Despite the large-scale characteristic of rebars, bars and profiles, Gerdau believes that it stands out from many of its competitors for its wide range of products, quality, consistent delivery performance and, the ability to fulfill large orders. Gerdau believes that it produces one of the most complete lines of bars and profiles. The variety of products offered by Gerdau is an important competitive advantage in a market where many customers seek to meet their needs with few key suppliers.

[**Table of Contents**](#TOC)

**Business Cyclicality and Seasonality**

The steel industry is highly cyclical. Consequently, the Company is exposed to fluctuations in the demand for steel goods that in turn cause fluctuations in the prices of these goods. Furthermore, since the production capacity of Brazil's steel industry exceeds its demand, it is dependent on export markets. The demand for steel goods and consequently the financial conditions and results of operations of steel producers, including the Company, are generally affected by fluctuations in the world economy and in particular the performance of the manufacturing, construction and automotive industries. Since 2003, the good performance of the world economy, especially in developing economies, such as China, has led to strong demand for steel goods, which contributed to historically high prices for Gerdau's steel goods. However, with the financial crisis that emerged in mid-2008, these prices have become unsupportable, especially given the expansion in world installed production capacity and the recent softening of demand. In the second quarter of 2008 and especially in early 2009, the United States and other European economies showed strong signs of a slowdown, which in turn affected many other countries. Over the past few years, developing economies have shown signs of a gradual recovery, while developed economies still present a challenging demand scenario.

In Gerdau's Brazilian and South 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 Gerdau'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 shipments.

**Information on the Extent of the Company's Dependence**

The Company is not dependent on industrial, commercial or financial agreements (including agreements with clients and suppliers) or on new production processes that are material to its business or profitability. The Company also has a policy of diversifying its suppliers, which enables it to replace suppliers without affecting its operations in the event of failure to comply with the agreements, except in the case of its energy and natural gas supply.

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

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 Ouro Branco 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.

Gerdau's operations are spread across various geographic regions, which provides a risk diversification of any electricity or natural gas supply problems in Brazil.

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**

***Price volatility***

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 ferroalloys are also important.

Although international ferrous scrap prices suffer high influence 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.

[**Table of Contents**](#TOC)

*Brazil and Special Steel Business Segments —* 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 contracts with scrap generators, especially scrap from industrial sources, 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.

Due to its size, the Ouro Branco mill has developed over the last few years a strategy to diversify its raw materials, which are supplied through various types of contracts and from multiple sources, which include: (i) coking coals imported from Colombia, United States, Canada, Russia, Australia and Peru as well as petroleum coke purchased from Petrobrás and charcoal chaff also acquired from other domestic suppliers; (ii) ferroalloys, of which 86% are purchased in the domestic market; and (iii) iron ore, which is mainly produced from its own mines and partially supplied by mining companies, most of them strategically located close to the plant.

*North America Business Segment —* The main input used by the Company's mills in North America is ferrous scrap, and has consistently obtained adequate supplies of raw materials, not depending on a smaller number of suppliers. Due to the fact that the United States are one of the largest scrap exporters in the world, the prices of this raw-material, in this country, may fluctuate according to supply and demand in the world's scrap market.

*South America Business Segment —* The main input used by the Company's mills in South America is ferrous scrap. This 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 cans to car bodies and white goods; and (ii) industrial scrap, which is composed of scrap from manufacturing processes, essentially steel bushings and flashings, steel turnings and even scrap generated by production processes at steel producers, such as Gerdau. In Brazil, the use of scrap in electric arc furnaces varies between scrap from obsolescence and industrial scrap. Special Steel mills mainly use industrial scrap.

Because ferrous scrap is one of its main raw materials in steel production, Gerdau is dedicated to improving its supply chain in various countries, aiming to develop and integrate micro and small suppliers into the Company's business. In Brazil, the main part of the scrap consumed by the Company comes from small scrap collectors who sell all their material to Gerdau, which provides a direct supply at more competitive costs for the Company. In North America, although smaller, the number is still significant, ensuring the competitiveness of the business in the region.

*Brazil and Special Steel Business Segments —* The price of steel scrap in Brazil varies by region and reflects local supply, demand and transportation costs. The Southeast is the country's most industrialized region and generates the highest volume of scrap. Due to the high concentration of players in this region, competition is more intense.

Gerdau has six scrap shredders, including a mega-shredder at the Cosigua mill in Rio de Janeiro, with capacity to process scrap in volumes superior to 200 carcasses of vehicles per hour.

*North America Business Segment* — Ferrous scrap is the main raw material. The availability of this input varies according to the level of economic activity, seasonality, export levels, climatic conditions and price fluctuations. Twelve units in the North America Business Segment have facilities for processing scrap within the mills, including crushers that supply much of their scrap demand. Considering that not all the scrap consumed comes from their yards, the rest of the demand is guaranteed through direct acquisitions or via resellers who originate and prepare the scrap.

In North America, all production units are semi-integrated mills or mini mills, in which results of operations are closely related to the cost of ferrous scrap and its substitutes, which are the main input of mini mills. Ferrous scrap prices are relatively higher during the winter months in the north hemisphere due to the impact of climate on collection and supply. More than half of North America's products are currently produced in electric arc furnaces with the use of ferrous scrap. Prices of ferrous scrap are subject to market forces beyond the Company's control, including demand from the United States and international steel producers, freight costs and speculation.

*South America Business Segment —* The price of scrap in South America varies widely from country to country in accordance with supply, demand and transportation cost.

[**Table of Contents**](#TOC)

***Pig Iron and Sponge Iron***

*Brazil Business Segment —* Brazil is an exporter of pig iron. Most of Brazil's pig iron is produced in the state of Minas Gerais by a number of small producers. Pig iron is a drop-in substitute for scrap and in Brazil it is an important component of the metal mix used to make steel in the mills. The price of pig iron follows domestic and international demand, and its cost production is basically composed by reducers and minerals.

*North America Business Segment —* The availability of scrap plays an important role for operations in North America. Sponge iron and pig iron are used in limited quantities only to produce steels with particular characteristics.

***Iron Ore***

Iron ore is the main input used to produce pig iron at Gerdau's blast furnace mills located in the state of Minas Gerais, southeastern Brazil. The pig iron is used in the melt shops together with scrap, to produce steel.

Iron ore is purchased in its natural form as lump ore, pellet feed or sinter feed, or agglomerated as pellets. The lump ore and pellets are loaded directly into the blast furnace, while the sinter feed and pellet feed need to be agglomerated in the sinter plant and then loaded into the blast furnace, to produce pig iron. The production of 1.0 tonne of pig iron requires about 1.6 tonnes of iron ore.

Iron ore consumption in Gerdau mills in Brazil amounted to 6.8 million tonnes in 2022, 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, albeit in smaller amounts. Additional inputs associated with the production of pig iron are thermal-reducer, as coal coke, charcoal or natural gas, which is used in blast furnace mills.

The Ouro Branco mill's significant raw materials and inputs also include solid fuels, comprising the metallurgical coal, used in the production of coke 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, the Company also uses the anthracite, solid fuel used in the production of sinter. The gas resulting from the production of coke and pig iron are reused for generation of thermal energy that can be converted in electric energy for the mill.

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 graphite electrodes that are available in the national and international market. Gerdau North America Business Segment 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 role in the production process, along with natural gas, which is used mainly in furnaces to re-heat billets in rolled steel production.

In Brazil, electricity is currently supplied to the Company's industrial units under two types of contracts:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Contracts in the Regulated Contractual Environment in which the Company is a " Captive Consumer " are used at the following units: Usiba and A ç onorte. These involve state-owned companies or holders of government concessions. In these contracts, prices are defined by the National Electric Power Agency (ANEEL).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Contracts executed in the Free Market Environment, in which Gerdau is a " Free Consumer, " are used by the following units: Ara ç ariguama, Charqueadas, Cosigua, Cearense, Ouro Branco, Divin ó polis, Bar ã o de Cocais, Riograndense, S ã o

[**Table of Contents**](#TOC)

José dos Campos, Cumbica, Cotia, Pindamonhangaba, Mogi das Cruzes and Miguel Burnier. The load of these units is served by a portfolio of contracts and by self-generation. The power supply contracts are entered into directly with generation and/or distributing companies at prices that are pre-defined and adjusted in accordance with conditions pre-established by the parties. The transmission and distribution rates are regulated and revised annually by ANEEL. The Ouro Branco mill generates internally approximately 70% of its energy needs, using the gases produced during the steelmaking process. As a result, this makes the plant has significantly lower exposure to the energy market than mini mills.

The Company holds the following power generation concession in Brazil:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Dona Francisca Energ é tica S.A. (DFESA) operates a hydroelectric power plant with nominal capacity of 125 MW located between Nova Palma and 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 (Cons ó rcio Dona Francisca) with the state power utility Companhia Estadual de Energia El é trica (CEEE). The shareholders of DFESA are Gerdau S.A. (51.82%), COPEL Participa çõ es S.A (23.03%), Celesc (23.03%), and Statkraft (2.12%).

The terms of the aforementioned generation concession agreements are for 39 years as of the signature of the agreement. As such: DFESA expires in 2037.

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.

In the United States, there are essentially two types of electricity markets: regulated and deregulated. In the regulated market, contracts are approved by Public Utility commissions and are subject to an approved rate of return. These regulated tariffs are specific to local distributors and generally reflect the average fuel costs of the distributor. In deregulated markets, the price of electricity is set by the marginal resource and fluctuates with demand. Natural gas in the United States is completely deregulated. The U.S. energy market is benefiting from the increased exploration of shale gas, which is driving down prices of both electricity and natural gas.

In Uruguay, electricity is purchased under agreements that are renewed automatically on an annual basis from the state-owned utility UTE. Natural gas is purchased from Montevideo Gas with prices set by the Argentinean export tariff agreement (fuel oil as substitute). During 2018, the plant operated mostly on fuel oil, due to competitive reasons.

In Peru, the Company has a current electricity contract until December 2025. The plant receives CNG (Compressed Natural Gas) by trucks and then is decompressed and distributed through internal pipeline to production processes.

Argentina uses natural gas (liquefied petroleum gas) as a substitute. The natural gas purchase agreement was renewed for another year. In 2008, Gerdau Sipar entered into a long-term agreement to supply the new mill's power requirements.

In Mexico, electricity is purchased under agreements regulated by the state-owned utility Companía Federal de Electricidad (CFE) and bilateral contracts with private companies. The natural gas agreements are annually and automatically renewed. Electricity and natural gas prices are indexed and adjusted monthly based on the NYMEX prices indices.

**Technology and Quality Management**

All Gerdau mills have a Quality Management System 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, and the concept of "Quality Function Deployment", a methodology through which technicians can identify and implement the customer requirements.

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

Gerdau 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 manufactured product high

[**Table of Contents**](#TOC)

standards of quality. Gerdau's technical specialists do planned visits, some are randomly selected, and some are scheduled visits, to its customers to check on the quality of the delivered products in order to guarantee the final user satisfaction for products purchased indirectly.

Due to the specialized nature of its business, the Gerdau 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 (Research and Development) responsible for new products and the optimization of existing processes.

International machinery manufacturers and steel technology companies supply most of the sophisticated production equipment that Gerdau 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. Gerdau has technology transfer and benchmarking agreements with worldwide recognized performance companies.

As is common with mini mill steelmakers, Gerdau usually acquires technology in the market rather than develops new technology through intensive process 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 an 28/34 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 (ECC) 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. Gerdau 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 operations in the United States and Brazil have their own credit departments for customer' credit analysis.

The Company's impairment loss on financial assets has been at low levels. On December 31, 2022, provision for expected credit losses was 1.8% based on gross account receivables per Note 5 to the Consolidated Financial Statements, compared to 1.9% on December 31, 2021 and 3.7% on December 31, 2020. 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 purchased insurance for its integrated mill Ouro Branco to insure against operating losses, which covers assets of approximately US$5.8 billion (R$30.5 billion as of December 31, 2022), including material damage to installations of US$4.6 billion (R$24.1 billion as of December 31, 2022) and losses of gross revenues of US$1.2 billion (R$6.4 billion as of December 31, 2022), 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 Ouro Branco mill remains effective until April 30, 2023. The Company's mini mills are also covered under insurance policies which insure against certain operational losses resulting from business interruptions.

**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

[**Table of Contents**](#TOC)

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.

**Material effects of government regulation on the Company's activities**

The Company's steel production activities are not subject to special authorizations other than the licenses and permits typical to the industry. The Company maintains a good relationship with the government agencies responsible for issuing common authorizations and does not have any history of problems in obtaining them.

Gerdau's mining operations in Brazil are subject to the rules of the Brazilian Mining Code and its regulation (Decree-Law 227, of February 28, 1967 and Decree 9,406, of June 12, 2018) and to the applicable mining legislation, with mining exploration governed by Mining Property Rights and Concessions.

Gerdau acquired the surface of the properties located in the polygon of the respective mining rights, as well as all other Mining Property Rights and Concessions, under an Agreement for the Sale of Assets and Assignment of Rights entered into by and between Gerdau Açominas S.A. and Companhia Paraibunas de Metais, Siderúrgica Barra Mansa S.A., Votorantim Metais Ltda., and Votorantim International Holding N.V., on May 19, 2004.

The Company's mining exploration activities are subject to the conditions and limitations imposed by the Federal Constitution of Brazil, the Brazilian Mining Code and related laws and regulations, which include requirements connected to, among other factors, how mineral deposits are used, occupational safety and health, environmental protection and restoration, pollution prevention and the health and safety of the local communities where the mines are located. The Brazilian Mining Code also establishes some requirements for the submission of notifications and information.

Companies authorized to economically explore mineral resources are required to pay royalties to the Federal Government, which distributes most of them to States and Municipalities. On July 26, 2017, Provisional Presidential Decree 789/17 was published, which was later converted into Federal Law 13,540/17, amending Federal Laws 7,990/89 and 8,001/90, which provide for the Financial Compensation for Exploration of Mineral Resources (CFEM). The structure for the charging of royalties was changed to the following:

1) TRIGGERING EVENT: the exploration of mineral resources will trigger the payment of CFEM upon:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the first sale of mineral asset (already mined mineral substance after its processing, if applicable);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the sale at auction, in the case of mineral assets acquired via judicial sale;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the first acquisition of mineral assets extracted under the system of mining permission (*lavra garimpeira*);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the consumption of mineral asset (use of mineral assets in a process that entails obtaining a new type of ore or its transformation into another product type).

2) CALCULATION BASE

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· in the case of sales, calculated based on gross sales revenue, less any taxes levied, with deductions for freight and insurance expenses prohibited;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· in the case of consumption, calculated based on the current price of the mineral asset in the market or the price reference, as defined by the regulatory agency of the mining sector. Since iron ore does not appear in the absolute list of the National Mineral Production Department (DNPM) Ordinance 239/2018, it is subject to the " current price " calculation base when transformed into another type of product, such as pig iron.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· in the case of exports, even for transactions in the free market (sales to third parties/unrelated third parties) and exports to companies not located in tax havens, the calculation base is the greater of the price reference defined by the Federal Revenue Department (PECEX method) and the export value;

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· in the case of mineral assets acquired via judicial sale, calculated based on the value of the sale at auction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· in the case of extraction under the system of mining permission (*lavra garimpeira*), calculated based on the value of the first acquisition of the mineral asset;

Financial compensation (CFEM) may or may not have to be paid on sales among companies of the same business group; Federal Law 13,540/17 does not establish any criteria for such.

For mineral assets shipped to another establishment of the same owner, for subsequent sale, even if subject to processing, the calculation base is the price charged in the final sale.

3) RATES: effective 11/1/2017

Rates of mineral substances:

---

| | |
|:---|:---|
| RATE | MINERAL SUBSTANCE |
| (VETOED) | (VETOED) |
| one percent (1%) | Rocks, sand, gravel, red clay and other mineral substances intended for immediate use in construction; ornamental rocks; mineral and thermal water |
| one point five percent (1.5%) | Gold |
| two percent (2%) | Diamond and other mineral substances |
| three percent (3%) | Bauxite, manganese, niobium and rock salt |
| three point five percent (3.5%) | Iron ore |

---

For iron ore, the rate is fixed at 3.5%. In this case, upon a justified need, the regulatory entity of the mining sector could exceptionally reduce the iron compensation rate from 3.5% to as low as 2% in order to not adversely affect the economic feasibility of deposits with low performance and profitability due to the iron content, production scale, payment of taxes and number of employees.

On December 26, 2017, Federal Law 13,575 was sanctioned, which created the National Mining Agency (ANM), eliminated the National Department of Mineral Production (DNPM), amended federal laws 11,046 of December 27, 2004, and 10,826 of December 22, 2003, and revoked Federal Law 8,876 of May 2, 1994, and the provisions of Decree-Law 227 of February 28, 1967 (Mining code). This law derives from Provisional Presidential Decree 791/2017 issued by the Ministry of Mines and Energy (MME) and submitted to the joint commission of the Senate in mid-2017 for approval. The wording of the federal law was published in the federal register *Diário Oficial da União* (DOU) on December 27, 2017, Issue: 247, Section 1, Pages 1 to 4.

It eliminates the National Department of Mineral Production (DNPM) and creates the National Mining Agency (ANM), a government agency linked to the Ministry of Mines and Energy responsible for promoting mineral exploration and developing the industry.

The Rate for Inspection of Mining Activities (TFAM), which the Executive Branch intended to create along with ANM, was not approved by the National Congress.

Gerdau holds environmental licenses for commercial operation of the mines located in the cities of Miguel Burnier and Várzea do in the Brazilian state of Minas Gerais.

[**Table of Contents**](#TOC)

The mining rights held by Gerdau cover 8,837.19 hectares, and the concessions are valid until the mining deposits are exhausted, provided the legal requirements are fulfilled annually. The table below lists the DNPM processes referring to the mining rights held by Gerdau:

**Mining Assets**

***Iron ore mines***

Gerdau's activities related to the iron ore mines began after acquiring the mining rights from the Votorantim Group, in the cities of Ouro Preto (district of Miguel Burnier), Itabirito and Barão de Cocais, in 2004. These areas are located in the Iron Quadrilateral region of Minas Gerais state, in Brazil, one of the country's most prominent mineral regions, as shown in the following figure.

Focusing on guaranteeing its iron ore self-sufficiency in Minas Gerais state and seeking opportunities to add value to the business by using its own mineral resources, Gerdau conducted studies up to 2014 to assess and implement projects for expanding its mining operations in order to become a player in the global iron ore market. However, given the current price of iron ore in the international market, Gerdau decided to focus only on iron ore production for achieving self-sufficiency.

[**Table of Contents**](#TOC)

***Location of Gerdau's mining operations***

![Graphic](ggb-20221231x20f015.jpg)

The current and future iron ore production units encompass mainly open-pit mines, processing plants, waste and tailing piles, and logistics and operational support infrastructure.

The current iron ore production units are the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Miguel Burnier/Dom Bosco Complex: includes the mines located in Miguel Burnier and in Dom Bosco;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· V á rzea do Lopes Complex;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Gongo Soco.

***Location and Access***

**Miguel Burnier/Dom Bosco Complex**

Miguel Burnier and Dom Bosco are located in the city of Ouro Preto, in the southwestern region of the Iron Quadrilateral region of Minas Gerais, in Brazil, around 80 km from Belo Horizonte and 5 km from Vila do Pires, on Highway BR-040. The Dom Bosco Mine is located approximately 11 km from the Miguel Burnier Mine. Vila do Pires is situated on both sides of Highway BR-040, in the northern region of the city of Congonhas. Access to the mines is via a three-kilometer unpaved road starting in the village of Miguel Burnier.

[**Table of Contents**](#TOC)

**Várzea do Lopes Complex**

Várzea do Lopes is located in the city of Itabirito, in the Iron Quadrilateral region of Minas Gerais, in Brazil, approximately 46 km from downtown Belo Horizonte. Access to the mine is from Belo Horizonte via Highway BR-040, heading towards Rio de Janeiro. Várzea do Lopes is located approximately 20 km from Miguel Burnier, in a straight line.

**Gongo Soco**

There are no mining activities at this location by the Company. The mining rights, as well as the mine, were leased by the company SPE MSA Trindade Mineração Ltda.

The image below represents what the Company believes to be the location of the current and eventual iron ore production units and their main access routes:

![Graphic](ggb-20221231x20f016.jpg)

**Investment Programs**

On February 22, 2022, the Company announced its capex projection for 2022 in the amount of R$4.5 billion. Disbursements made in 2022 totaled R$4.3 billion. With the worsening of the pandemic in the first half of 2021 and the difficulties caused by bottlenecks in some global supply chains, approximately R$500 million have not been disbursed and was included for the year 2022.

On February 28, 2023, Gerdau S.A. approved its new investment plan in the amount of R$5.0 billion for 2023.This investment plan is divided into two fronts: (i) Maintenance and (ii) Expansion and Technological Updating.

Maintenance projects are associated with the concept of reinvestment of depreciation over the years to ensure the good functioning of plants.

Meanwhile, Expansion and Technological Updating projects are related to the growth, technological updating and modernization of the business segments, with a focus on improving Environmental, Social and Governance (ESG) practices and sustainable development.

[**Table of Contents**](#TOC)

Of the total planned for 2023, investments that return environmental benefits are expected to be roughly R$830 million, approximately 4% higher than the amount invested in 2022. These investments include: expanding forest assets, updating and improving environmental controls and technological improvements that increase energy efficiency and reduce greenhouse gas emissions.

The Company's expenditures in its investment plan will be directly related to the safety of our operations and to the pace of demand in our markets, as well as based on criteria involving the return on capital invested and the consequent cash generation.

![Graphic](ggb-20221231x20f017.jpg)

**Environmental Issues**

Gerdau S.A is currently in compliance with environmental regulations. The Company also believes that there are no environmental issues that could affect the use of its fixed assets.

In 2022, Gerdau S.A. invested R$639.31 million in the improvement of its eco-efficiency practices and in technologies for the protection of the air, water and soil.

***Environmental Regulations***

In all of the countries in which the Company operates, it is subject to federal, state and municipal environmental laws and regulations governing, but not limited to, the air emissions, wastewater discharges and solid and hazardous waste handling and disposal. Its manufacturing facilities have been operating under the applicable environmental rules. The respective permits and licenses require compliance with conditions and 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.

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, civil and administrative sanctions, as well as any costs to repair the actual damages resulting from such harm.

The steel industry uses and generates substances that can cause environmental damages. The Company's Management conducts surveys periodically to identify areas potentially impacted and recorded as its best estimate of the costs for inspecting, treating and cleaning potentially impacted areas the amounts of R$484,652 on December 31, 2022 (R$262,081 recognized as current liabilities and R$222,634 as non-current liabilities), R$575,709 on December 31, 2021 (R$231,711 recognized as current liabilities and R$343,998 as non-current liabilities) and R$297,094 on December 31, 2020 (R$125,992 recognized as current liabilities and R$171,102 as non-current liabilities). The Company adopted assumptions and estimates to determine the amounts involved that could vary in the future due to the conclusion of the inspection and the assessment of the actual environmental impact at the time of the ultimate settlement. See Note 22 - Environmental Liabilities.

[**Table of Contents**](#TOC)

***Brazilian Environmental and Regulatory Legislation***

The Company's activities are subject to wide-sweeping Brazilian environmental legislation at the federal, state and municipal levels that encompass, 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, civil and administrative liabilities on individuals 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 significant impact on its business, potential environmental crimes or infractions could subject the Company to penalties that include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· fines that at the administrative level could reach as high as R$1 billion, and that could be influenced by the wrongdoer ' s economic capacity and past record, as well as the severity of the facts and prior history, that could be potentially doubled or tripled in case of repeat offenders;

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

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

The application of environmental liability in criminal sphere depends on evidence of intent (intention) or fault (negligence and/or recklessness) and, is considered subjective. Therefore, individuals only would be prosecuted or convicted to the extent of their action, intention or fault. In the case of the administrative sphere, recent judicial precedents provide for subjective environmental liability as well, although most environmental agencies apply administrative environmental liability regardless of proof of intent or fault.

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 intent or fault. In this case, acknowledging the causal link between the action and the damage is enough to imputation of civil responsibility As a result, hiring of outsourced companies to intervene in its operations to perform services such as final disposal of solid waste does not exempt the Company from liability for any environmental damage that may occur.

Environmental legislation also provides for piercing the corporate veil, affecting shareholder assets, whenever the lack of solvency of an entity represents an impediment to recovery of environmental damages.

***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 significant 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.

[**Table of Contents**](#TOC)

***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 most cases that involve significant environmental impact, the 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, and may subject the wrongdoer to administrative fines, at the federal level (subject to being doubled or tripled in the case of repeat violations), a Environmental legislation also provides for piercing the corporate veil, affecting shareholder assets, whenever the lack of solvency of an entity represents an impediment to recovery of environmental damages 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.

***Decarbonization Strategy***

In 2019, the Company engaged in a review of materiality through which it determined the most significant material issues - all of them linked to the SDGs (Sustainability Development Goals) to guide our strategy and management initiatives and guide the way in which we communicate with our stakeholders and society in general. One of the issues identified as most significant was "Mitigation and adaptation to climate change". GHG emissions are a key issue in the debate on climate change and a sensitive point for the steel industry, given the level of emissions from its production facilities in relation to the industrial sector as a whole. In 2022, Gerdau had its material issues revised and this topic is still considered material for the Company.

The Company defines its risk management guideline and procedure based on business analysis, including issues related to climate change and the ESG Scorecard indicators. Industry trends that can impact business in the short-, medium- and long-term, as well as environmental, social and governance factors, image and legislation are assessed.

The identified risk factors related to climate change are related to unexpected interruptions in the production capacity of the Company's main units and facilities that would increase production costs, reducing sales and earnings in the affected period. The Company could be affected by risks,such as:

● Reduced availability of electricity arising from a period of water crisis: the production of crude steel is an electricity-consuming process, especially in steel mills that use electric arc furnaces. Electricity is an important component for the production of these units, as is natural gas, although to a lesser extent. Electricity cannot be replaced by another energy source in the Company's mills and rationing or interruptions in supply can affect the production of these units.

● Fires or severe weather conditions: Unforeseen periods of drought can impair the performance of our forest areas, reducing the availability of the bio-reducer for our operating units that use this input; Floods can result in unforeseen periods of production stoppage, among others.

● Water shortage resulting from a period of water crisis: Reduction of water withdrawal for the production process, leading to a reduction in production.

[**Table of Contents**](#TOC)

Such risks would increase production costs, reducing sales and earnings in the affected period as a result of unexpected events. As a consequence, the Company is susceptible to periods of stoppage or reduction of production in the steel mills, which may also occur in the future. Interruptions in production capacity may adversely affect Gerdau's productivity and operating results. In addition, any interruption in production capacity may require additional troubleshooting expenses which would impact the Company's cash flow. As a result, long business interruptions can also damage the Company's reputation and lead to the loss of customers, which can have a negative impact on business, results of operations and cash flows. The Company could also be affected by transition risks related to policy, legal, technology, market and reputation risks.

In 2021, the Company prepared the GHG inventory of all of its global industrial units (base year, 2020). Since then, the data has been audited by a third party, following ISO 14064 (Greenhouse gases), and reporting its GHG emissions management on CDP since 2021 (2020 base year), CPD is a reference entity in the evaluation of sustainable actions. In 2022, Gerdau kept its B score, a score higher than the global average and the sector's score, reinforcing the Company's commitment to the sustainability of its operations, in line with the ESG criteria. Also in 2022 (base year 2021), for the first time, Gerdau reported CDP Water Security for Brazil operations and received a B- score, reinforcing the Company's commitment to transparency.

With the support of specialized consultants, we study the scenarios of productive and technological changes with the lowest effective carbon cost to define goals and guide our strategy. Consistent with this, the Company adopted the MACC "Marginal Cost Curve Abatement" and structured and published on February 1, 2022 the goal of reducing greenhouse gas emissions related to scope 1 and 2 by 2031, from 0.93 t of CO₂e per ton of steel produced to 0.83 t of CO₂e per ton of steel produced, a level that will leave us with a volume of emissions less than half the world average for the steel sector, which today is 1.93 t of CO₂e according to the World Steel Association. This target is factored in our Long-Term Compensation (ILP) program.

Gerdau's production model and efforts for over a century have placed the Company at the vanguard on the issue of greenhouse gas emissions. Currently, we have one of the lowest emission averages in the steel industry, which is equivalent to approximately half of the global industry average.

● 71% of the steel we produce comes from recycling of ferrous scrap: Gerdau S.A. is the largest recycler in Latin America, transforming 11 million tonnes of scrap into steel. This enables us to promote a circular economy, saving natural resources and reduce energy consumption and greenhouse gas emissions.

● World's largest charcoal producer: The Company has more than 250,000 hectares of forests. Our planted forests are sources of renewable raw material in the production of charcoal, a bioreducer used to produce pig iron, resulting in decreased emissions of greenhouse gases.

● High gas reuse level: Currently, we are leaders in managing greenhouse gases and being renowned as a benchmark for industry entities. Our constant efforts include the use of renewable sources, recycling, reduction of raw material consumption and energy efficiency.

Our reduction from 0.93t CO2e / t steel (base year 2020) to 0.83t CO2e / t steel, by 2031, in scopes 1 and 2 prioritizes:

● Greater energy and operational efficiency;

● Higher use of scrap;

● Expansion of our forestry base and renewable energy sources; and

● Investment on new technologies and open innovation.

With this reduction, we are reaching a new level, at which the global steel industry would have to cut about 50% its current greenhouse gas emissions to reach it. In 2031, once we achieve this target, the Company will be in a further strategic position among the world's most efficient steel producers in terms of greenhouse gas emissions.

The Company aims to be carbon neutral by 2050, for this, disruptive technologies are necessary in steel production, which are not yet economically and operationally feasible on an industrial scale. To contribute to this scenario, we continue to study and collaborate with diverse partners and entities in the sector to seek low carbon solutions.

Public policies and measures to reduce greenhouse gas emissions from industrial processes will also be necessary. Our efforts are also dedicated to clean and renewable energy solutions. The Company has already announced the construction of a solar complex in Brazil. Moreover, we will continue to streamline our production processes and invest in new energy matrices and open innovation.

***Areas of permanent forest preservation and legal reserves***

Some activities of the Company, mainly those involving reforestation to produce thermal-reducer used in its industrial units, are subject to the Brazilian Forest Code.

The Code determines that some areas, due to their importance for the preservation of the environment and water resources, are considered permanent preservation areas (APP), such as, for example, areas adjacent to rivers or natural or artificial reservoirs, hill tops and slopes hills with a slope greater than 45 °. At Gerdau's forestry units, permanent preservation areas are an integral part of the business, being protected and in compliance with the legislation.

Moreover, depending on the region where the property is located, the Code requires rural land owners to restore and preserve between 20%, 35% or 80% of areas containing native vegetation. The maintenance of these percentages of native vegetation is important because it guarantees the preservation of the local natural vegetation, perpetuating the genetic resources and the biodiversity of each Brazilian biome. Gerdau maintains its Legal Reserve areas preserved and in accordance with governing legislation.

**Brazilian Economic Conditions**

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

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 2022, Brazilian GDP increased 2.9% (equivalent to US$1.6 trillion Nominal GDP) driven to services, industry and agribusiness sectors. Inflation, as measured by the IPCA index, was 12.1%. The average CDI rate in the year was 12.4%. The Brazilian *real* depreciated by 1.75% against the U.S. dollar, ending the year at R$5.20 to US$1.00.

In 2021, Brazilian GDP increased 4.7% (equivalent to US$8.6 trillion Nominal GDP) driven to services, industry and agribusiness sectors. Inflation, as measured by the IPCA index, was 10.1%. The average CDI rate in the year was 4.4%. The Brazilian *real* depreciated by 7% against the U.S. dollar, ending the year at R$5.58 to US$1.00.

In 2020, Brazilian GDP decreased 4.1 % (equivalent to US$7.4 trillion Nominal GDP) mainly as a result of the COVID-19 pandemic. Inflation, as measured by the IPCA index, was 10.1%. The average CDI rate in the year was 2.75%. The Brazilian *real* depreciated by 29% against the U.S. dollar, ending the year at R$5.20 to US$1.00.

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 by 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 result in increases in the Company's financial expenses and debt service obligations.

The interest rates that the Company usually 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 2022, according to the IMF (International Monetary Fund) the U.S. Real GDP increased by 2.7%. Inflation, as measured by the CPI, was 6.5%. The average Fed Funds rate (the interest rate established by the U.S. Federal Reserve) was 4.25%.

In 2021, according to the IMF (International Monetary Fund) the U.S. Real GDP increased by 10.0%. Inflation, as measured by the CPI, was 7%. The average Fed Funds rate (the interest rate established by the U.S. Federal Reserve) was 0.25%.

In 2020, according to the IMF (International Monetary Fund) the U.S. Real GDP decreased by 2.3%. Inflation, as measured by the CPI, was 1.4%. The average Fed Funds rate (the interest rate established by the U.S. Federal Reserve) was 0.25%.

**Impact of 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.

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, gains and losses from debts contracted for acquisition of overseas investments are designated as a hedge of net investment in foreign subsidiaries and are also recorded directly in shareholders' equity. The operations of Gerdau in Brazil have both liabilities and assets denominated in foreign currency, with the amount of assets exceeding 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.

[**Table of Contents**](#TOC)

International steel prices have experienced ups and downs throughout the last several years. From 2017 until 2021, the Turkish Rebar average price (the measure most used in the market, since the turmoil in the world economy after the 2008 crisis, when CIS prices skyrocketed to US$1,205), was US$476 in 2017, US$535 in 2018 then US$450 in 2019. In 2021, the year's average price was substantially higher compared to 2020, going to US$682 from US$445, following the increase in the cost of raw materials and the growth of consumption.

*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. Gerdau exports products from Brazil to customers in other continents with whom we have long-established commercial relations. In 2021, exports were 13% lower than 2020, going from 825 to 714 million tonnes, which represented 12.4% of total shipments from Brazil operations. Export revenue totaled R$2,933 million in 2021 (R$2,018 million in 2020).

*Production costs —* raw materials account for the highest percentage of the Company's production costs. Metallic inputs, which includes scrap, pig iron, iron ore, coke and metallic alloys, represented approximately 57.3% of production costs in 2021, while Energy and Reducing Agents, which represents the cost of coal, electricity, oxygen, natural gas and fuel oil, accounted for 11.2%. Personnel totaled 14.8% of production costs and Specific Materials, which includes refractories, electrodes, rolling cylinders, rollers, guides, carburants and lime, were 8.2% of total production costs. The table below presents the production costs breakdown by business segment:

**Significant events affecting financial performance during 2022 and 2021**

According to the World Steel Association (worldsteel), steel production came to 1.87 billion tonnes in 2022, down 4.2% from 2021. The highlight was the Americas, where Gerdau's operations are located, which registered continuing high levels, even with the 4.7% drop in 2022 compared to 2021. Gerdau's shipments reached 11.9 million tonnes, generating net sales of R$82.4 billion, 5.2% higher than in 2021. The Company's intense focus on operating efficiency translated into a strong net income of R$11.5 billion in 2022.

In 2022, shipments to the industrial sector registered excellent performances in the agriculture, energy, machinery and highway equipment, capital goods and yellow line sectors, which benefited from demand in the domestic market, the location of the supplier base and opportunities in the export market given foreign exchange rates. Meanwhile, the infrastructure sector presented a positive scenario. Note that at end-2022, the Construction Industry Confidence Index (FGV) reached 95.3 points, down from 95.3 points in November. In North America, demand from the non-residential construction and industrial sectors remained at suitable levels. According to US Census Bureau, total investments in construction (CPIP- Construction Put-in-Place) grew by 10.6% in 2022, to US$1.8 trillion. Note that the leading indicator for non-residential construction (ABI) recovered to strong expansion territory, reaching 49.3 points in December 2022. The industrial sector also remained strong, as shown by the Institute for Supply Management (ISM) index, which reached 48.4 points in December 2022. In South America, steel production and shipments grew in 2022 compared to 2021, led by the good performance of the construction sector, which recovered to ideal levels in all countries of the sector, especially in Argentina. Lastly, in the Special Steel Business Operation, in Brazil, the heavy vehicle sector in 2022 registered good performance, . According to ANFAVEA, heavy vehicle production grew 5.4% in the year of 2022 compared with 2021, driven by robust activity in the construction, agribusiness and machinery and equipment sectors. In the United States and Canada, the oil and gas industry staged a recovery, with the total number of operating rigs in the U.S. reaching 689 on average in 2022, compared to 604 in 2021, according to Baker Hughes U.S. Rotary Rig Counts.

*COVID-19 Pandemic* – Despite the gradual recovery in our business divisions, the year 2022 still had economic impacts caused by the coronavirus (COVID-19) pandemic. China enacted a COVID-19 Zero policy, which only ended in December 2022. The continuity of the pandemic imposed constraints on various sectors of the economy, which suspended production, shipments, sales and services, etc.

[**Table of Contents**](#TOC)

For Brazil and South America segments, they show resilience in the year, with economic activity at levels higher than those seen in the pre-pandemic period, notably in the civil construction and industry sectors. For Special Steel segment, we had a gradual recovery in the automotive sector - favored by the normalization of the supply of chips and semiconductors, a sector greatly affected during the COVID-19 pandemic. For North America segment, a good recovery, with highlights for the Non-residential Construction, Industry and Distribution sectors, which remain resilient.

*Exchange rate —* The Company has designated a portion of its debt denominated in foreign currency and contracted by companies in Brazil as a hedge for a portion of the net investments in foreign subsidiaries. As a result, the effects from exchange variation gains or losses on the portion of debt designated for hedge accounting are also recognized in shareholders' equity, in accordance with IFRS. The subsidiaries that issued the debt are not subject to income taxes and as such there is no income tax effect on the exchange gains and losses on the debt. However, the subsidiaries have loaned the proceeds to other entities in Brazil with terms identical to those of the Ten-Year Bonds. The payable by the subsidiaries in Brazil to the foreign subsidiaries denominated in US dollars generates exchange gains (losses) that are taxable and results in income tax recognized in the income statement, while these exchange variances are eliminated in consolidation with the offsetting exchange gains (losses) recognized by the foreign subsidiaries.

Starting from April 1, 2012, with the objective of eliminating the tax effect from the exchange variance of these debts, the Company designated part of its debt in foreign currency as a hedge for a portion of the investments in subsidiaries located outside Brazil. As a result, the exchange variation generated on the operations of Ten/Thirty Years Bonds in the amount of US$1.1 billion (equivalent to R$5.7 billion as of December 31, 2022) (designated as hedges) is recognized in the Statement of Comprehensive Income.

**A.** **Results of Operations**

All outstanding derivative financial instruments are monthly reviewed by the Financial Risk Management Committee, which validates the fair value of such financial instruments. All gains and losses in derivative financial instruments are recognized by its fair value in the Consolidated Financial Statements of the Company.

*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. The Company uses derivatives and other financial instruments to reduce the impact of market risks on its financial assets and liabilities or future cash flows and earnings. Gerdau has established policies to assess market risks and to approve the use of derivative financial instruments transactions related to those risks. The Company enters into derivative financial instruments to manage the above mentioned market risks and never for speculative purposes.

*Policy for determining fair value*: the fair value of the derivative financial instruments is determined using models and other valuation techniques, which involve future prices and curves discounted to present value as of the calculation date. Amounts are gross before taxes. Due to changes in market rates, these amounts can change up to the maturity or in situations of early settlement of transactions.

The derivative financial instruments may include: interest rate swaps, cross currency swaps, currency options contracts and currency forward contracts.

*Dollar forward contracts*: the Company entered into NDF operations (Non Deliverable Forward) in order to mitigate the foreign exchange risk on assets and liabilities denominated in foreign currencies, mainly U.S. dollar. The counterparties of these transactions are financial institutions with low credit risk.

The effects of financial instruments are classified as follow:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**C.** **RESEARCH AND DEVELOPMENT, PATENTS AND LICENCES, ETC.** 

All Gerdau mills have a Quality Management System 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

[**Table of Contents**](#TOC)

the assessment of process variables, and the concept of "Quality Function Deployment", a methodology through which technicians can identify and implement the customer requirements.

Given this level of quality management, mills are ISO 9001 or ISO TS 16949 certified, as well as a sort of certification of products and laboratories, according demands. In general, production, technical services and quality teams are responsible for developing new products to meet customer and market needs.

Gerdau 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 manufactured product high standards of quality. Gerdau's technical specialists do planned visits, some are randomly selected, and some are scheduled visits, to its customers to check on the quality of the delivered products in order to seek the final user satisfaction for products purchased indirectly.

Due to the specialized nature of its business, the Gerdau 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 (Research and Development) responsible for new products and the optimization of existing processes.

International machinery manufacturers and steel technology companies supply most of the sophisticated production equipment that Gerdau 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. Gerdau has technology transfer and benchmarking agreements with worldwide recognized performance companies.

As is common with mini mill steelmakers, Gerdau usually acquires technology in the market rather than develops new technology through intensive process 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**D.** **TREND INFORMATION** 

According to the World Steel Association (Worldsteel), steel production came to 1.9 billion tonnes in 2022, equal to levels from 2021. In the Americas, where Gerdau's operations are located, Gerdau produced 12.7 million tonnes of steel in 2022, which registered continuing high levels, even with the 4.7% drop in 2022 compared to last year. Gerdau's shipments reached 11.9 million tonnes, generating net sales of R$82.4 billion, 5.2% higher than in 2021. The Company's intense focus on operating efficiency translated into a net income of R$11.5 billion in 2022.

We believe that the scenario for 2023 remains positive for the construction sector in the Americas. Specifically in the U.S., the government has announced, as an example, funds of US$2.1 billion to revitalize bridges. Steel demand has been positively influenced by the level of activity in the construction sector, which is expected to grow by more than 6% this year. In particular, the infrastructure segment should advance 16% by 2023, driven by projects linked to the infrastructure investment package, the results of which are beginning to be felt. For the automotive industry, the prospects are good for the light vehicle market due to the gradual recovery in semiconductor inventories.

The Company continues to invest in its operations and to develop projects that can create value, such as Gerdau Next, the new business arm that offers solutions in construction, sustainability, mobility, digital sales, etc., that is absorbing opportunities in an ever more dynamic market.

The COVID-19 pandemic continues to impact global economic activity and represents the risk that the Company, employees, service providers, suppliers, customers and other business partners may be prevented from carrying out certain business activities for an indefinite period, including due to stoppages that can be requested or mandated by government authorities or elected by companies as a preventive measure.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**E.** **CRITICAL ACCOUNTING ESTIMATES** 

Critical accounting estimates are those that 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 estimates and assumptions

[**Table of Contents**](#TOC)

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 estimates and assumptions derived from historical experience and various other factors that it deems reasonable and significant. 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, the Company presents below the subjects that demand critical accounting estimates:

● revenue recognition;

● the recoverable amount of goodwill and long-lived assets;

● provisions for tax, civil and labor claims;

● recoverability of deferred tax assets;

● estimates in selecting interest rates, return on assets, mortality tables and expectations for salary increases; and

● long-term incentive plans through the selection of the valuation model and rates;

***Revenue recognition***

Net sales are presented net of taxes and discounts. The significant judgment made by the Company is presented in Note 2.17 and regarding revenue recognition it considers that revenue is derived from the single performance obligation to transfer its products under arrangements in which the transfer of control of the products and the fulfillment of the Company's performance obligation occur at the same time and that revenue from the sale of goods is recognized when the Company has transferred control of the goods to the buyer and the buyer obtains the benefits from the goods, the potential cash flows and the amount of revenue (the transaction price) can be measured reliably, and the consideration is to be transferred, which means it is probable that the Company will collect the consideration to which it is entitled to in exchange for the goods.

The significant judgment also considers whether the customer has obtained control over the asset depends on when the goods are made available to the carrier or the buyer takes possession of the goods, depending on the delivery terms. For the Company's operations, generally the criteria to recognize revenue has been met when its products are delivered to its customers (CIF term) or to a carrier who will transport the goods to its customers (FOB term) and these are the point in time when the Company has completed its performance obligations. Revenue is measured at the transaction price of the consideration received or receivable, the amount the Company expects to be entitled to.

The Company's products follow industry production standards for its applications. Historically, only a small portion of the Company's products are returned or have claims filed against the sale as result of quality complaints or other problems. Claims may be one of the following: product shipped and billed to an end customer that did not meet industry quality standards, such as physical defects in the goods, goods shipped to the wrong location or goods shipped outside acceptable time parameters. The Company estimates the consideration for such claims and reduces the amount of revenue recognized.

The warranties and claims arise when the product fails on the criteria mentioned above. Sales-related warranties associated with the goods cannot be purchased separately and they serve as an assurance that the products sold comply with agreed specifications. Accordingly, the Company accounts for warranties in accordance with IAS 37. Warranties and claims represent immaterial amounts to the Company.

***The recoverable amount of goodwill and long-lived assets;***

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

[**Table of Contents**](#TOC)

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 combinations and assets with indefinite useful lives 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. The reduction in recoverable amount must be recorded in income for the year.

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 as if the impairment had not been recorded.

The Company evaluates the recoverability of goodwill at least 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.

The impairment test of these assets is assessed based on the analysis of facts and circumstances to perform the impairment test annually in December or being anticipated whenever changes in events or circumstances indicate that the goodwill and other long-lived assets may be impaired.

The Company performs 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 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. Although the projections made by the Company already provide a challenging scenario, events manifested in a greater intensity than that anticipated in the assumptions made by management, may lead the Company to revise its projections of value in use and eventually result in impairment losses.

Goodwill that forms part of the carrying amount of an investment in an associate or in a joint venture 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 joint venture 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 joint venture. Accordingly, any reversal of that impairment loss is recognized to the extent that the recoverable amount of the investment subsequently increases.

The period for projecting the cash flows for the goodwill impairment test was five years. The assumptions used to determine the value in use based on the discounted cash flow method include analysis prepared in dollars, such as: projected cash flows based on management estimates for future cash flows, exchange rates, discount rates and growth rates on perpetuity. The cash flow projections already reflect a competitive scenario, as well as macroeconomic challenges in some geographies in which the Company operates. The perpetuity was calculated considering stable operating margins, levels of working capital and investments. The perpetuity growth rates considered in the 2022 test were: a) North America: 3% (3% in December 2021); b) Special Steel: 3% (3% in December 2021); c) South America: 3% (3% in December 2021); and d) Brazil: 3% (3% in December 2021).

The post-tax discount rates used were determined taking into consideration market information available on the date of performing the impairment test. The Company adopted distinct rates for each business segment tested with the purpose of reflecting the differences among the markets in which each segment operates, as well as the risks associated to each of them. The post-tax discount rates used were: a) North America: 9.75% (9.50% in December 2021); b) Special Steel: 10.75% (10.50% in December 2021); c) South America: 18.00% (15.00% in December 2021); and d) Brazil 11.75%: (11.25% in December 2021). As required by the accounting standard, the Company made a calculation to determine the discount rates, before income tax and social contribution (gross rate of tax effects) and this calculation resulted in the following discount rates for each segment: a) North America 12.28% (12.05% in December 2021); b) Special Steel: 13.81% (13.29% in December 2021); c) South America: 26.47% (21.21% in December 2021); and d) Brazil: 15.56% (15.13% in December 2021).

[**Table of Contents**](#TOC)

Discounted cash flows are compared to the book value of each segment and result in the recoverable amount that exceeded book value as shown below: a) North America: R$10,426 million (R$5,769 million in 2021); b) Special Steel: R$5,299 million (R$4,238 million in 2021); c) South America: R$1,074 million (R$2,248 million in 2021); and d) Brazil: R$3,632 million (R$8,994 million in 2021).

The Company performed a sensitivity analysis in the assumptions of discount rate and perpetuity growth rate, due to the potential impact in the discounted cash flows. An increase of 0.5 percentage points in the discount rate of each segment's cash flow would result in a recoverable amount that exceeded book value as shown below: a) North America: R$8,749 million (R$4,337 million in 2021); b) Special Steel: R$4,329 million (R$3,301 million in 2021); c) South America: R$953 million (R$2,057 million in 2021); and d) Brazil: R$2,306 million (R$7,582 million in 2021). On the other hand, a decrease of 0.5 percentage points in the perpetuity growth rate of the cash flow of each business segment would result in a recoverable amount that exceeded book value as shown below: a) North America: R$9,161 million (R$4,679 million in 2021); b) Special Steel: R$4,586 million (R$3,545 million in 2021); c) South America: R$1,011 million (R$2,135 million in 2021); and d) Brazil: R$2,673 million (R$7,962 million in 2021).

The recoverability review process is subjective and requires significant judgments through analysis performed. The determination of fair value for the Company's operating segments, based on projected cash flows, may be negatively impacted if the economic global recovery happens slower than what management expected during the preparation of financial statements in December 2022.

***Provisions for tax, civil and labor claims***

The significant judgment is related to recognition and measurement of provisions. Information regarding provisions for tax, civil and labor liabilities are presented in Note 19 of the Consolidated Financial Statements contained herein. The Company recognizes provisions for liabilities and probable losses that have been incurred when it has a present obligation as a result of past events, it is probable that the Company will be required to settle the obligation and a reliable estimate of the amount of the obligation can be made. If the effect of the time value of money is material, provisions are discounted using a current pre-tax rate that reflects, where appropriate, the risks specific to the liability. The table below informs amounts of tax, labor and civil provisions:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  |  | **2022** |  | **2021** |
| a) Tax provisions |  | 1,530,040 |  | 1,270,473 |
| b) Labor provisions |  | 463,452 |  | 435,803 |
| c) Civil provisions |  | 32,511 |  | 34,750 |
|  |  | 2,026,003 |  | 1,741,026 |

---

a) Tax Provisions

Tax provisions refer mainly to discussions related to ICMS, IPI, Income tax and social contribution, social security contributions, offsetting of PIS and COFINS credits and incidence of PIS and COFINS on other revenues.

b) Labor Provisions

The Company is party to a group of individual and collective labor and/or administrative lawsuits involving various labor amounts and the provision arises from unfavorable decisions and/or the probability of loss in the ordinary course of proceedings with the expectation of outflow of financial resources by the Company.

c) Civil Provisions

The Company is party to a group of civil, arbitration and/or administrative lawsuits involving various claims and the provision arises from unfavorable decisions and/or probable losses in the ordinary course of proceedings with the expectation of outflow of financial resources for the Company.

***Recoverability of Deferred Tax Assets***

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.

[**Table of Contents**](#TOC)

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, and are consistent with recoverability described above.

Due to the lack of expectation to use tax losses, negative social contribution base and deferred exchange variation arising from some operations in Brazil, the Company did not recognize a portion of tax assets of R$239,989 as of December 31, 2022 (R$240,231 as of December 31, 2021), which do not have an expiration date. The subsidiaries abroad had R$1,105,130 as of December 31, 2022 (R$1,256,438 as of December 31, 2021) of tax credits on capital losses for which deferred tax assets have not been booked and which expire between 2029 and 2035 and also several tax losses of state credits in the amount of R$334,475 as of December 31, 2021 (R$1,285,373 as of December 31, 2021), which expire at various dates between 2023 and 2044. Quantitative information regarding Deferred income and social contribution taxes booked as well as tax assets not booked due to the lack of expectation to use are presented in Note 8 of the Consolidated Financial Statements contained herein.

***Estimates in selecting interest rates, return on assets, mortality tables and expectations for salary increases***

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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i) The cost of pension and other post-employment benefits provided to employees is actuarially determined using the projected unit of 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 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 on 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, return on plan assets, future increases in health care costs, and rate of future compensation increases. In addition, actuarial computations include other factors whose measurement involves judgment 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.

The tables below show a summary of the assumptions used to calculate the defined benefit plans in 2022 and 2021, respectively:

---

| | | |
|:---|:---|:---|
|  | **2022** | **2022** |
|  | **Brazilian Plan** | **North America Plan** |

***Long-term incentive plans through the selection of the valuation model and rates***

The Company settles its Long-term incentive plans by delivering its own shares, which are held in treasury until the exercise of the options by the employees. Additionally, the Company granted the following long-term incentive plans: Restricted Shares and Performance Shares, as presented in Note 27.

**Quantity Summary of Restricted Shares and Performance Shares:**

**Family Relationships**

André Bier Gerdau Johannpeter, Claudio Johannpeter and Guilherme Chagas Gerdau Johannpeter are cousins. Guilherme Chagas Gerdau Johannpeter and Richard Chagas Gerdau Johannpeter are brothers.

**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. Except as described in this document, there are no pending legal proceedings to which any Board Member or Executive Officer is a party against the Company. Apart from statutory severance benefits, none of the Board Members or Executive Officers are entitled to any contractual benefits upon termination of employment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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 good market practices as adopted by other companies. The variable portion of the compensation package is tied to annual goals. These goals are measured against standards clearly specified that are intended to support and motivate overachievement of individual and teams results.

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

The Company uses several assessment methods, including Performance Assessment and Assessment of potential and readiness for succession. It aims to identify the behaviors and deliveries of the Directors as well as monitor individual development according to the company's strategies and business management.

[**Table of Contents**](#TOC)

In 2022, the cost of management compensation, in salaries, variable compensation, benefits and terminations, was R$63.8 million. The cost of management's social charges totaled R$20.5 million. The total compensation paid to Managers and Directors was R$84.3 million. The variable remuneration of directors is determined based on Gerdau's financial results and individual performance evaluation. Fiscal Council members are not eligible for variable remuneration.

Gerdau Group sponsors Pension Plans for its subsidiaries in Brazil and abroad. About 5% of participants are in the Defined Benefit plans and 95% in a Defined Contribution plan.

During 2022, Gerdau's contribution to the Gerdau Plan with respect to the executive officers amounted to R$1,9 million to the Defined Contribution Plan. This sum includes only that portion of contributions for executives who do not currently receive retirement benefits. These benefits are in no way different from those offered to the other employees of the Company.

On April 30, 2003, Gerdau's shareholders approved a new compensation program for strategic employees in the Company known as the Long-Term Incentive Program. This 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 which latter was eliminated as of April 28, 2005. From 2005 on, in order to align their potential total compensation to market measures, the Board members were granted a number of shares representing 120% of their base salary. This modification of the long-term incentive program was approved by the Compensation and Succession Committee in February 2006. In 2007, the Compensation and Succession Committee approved a change in the grant to the Chief Executive Officer (CEO) and the Chief Operating Officer (COO) to the equivalent of 50% of their annual base salaries. In order to align the potential total compensation to market measures, the Compensation and Succession Committee approved respectively in 2012 and in 2013, to the Chief Executive Officer (CEO) and to the Chief Operating Officer (COO) a change to the grant to 75% and then to 120% of their annual base salaries and to the Vice-Presidents to 30% and then to 40%. In order to align the potential total compensation to market, the Compensation and Succession Committee approved a change to 2018 in the grant to the Chief Executive Officer (CEO) to the equivalent of 150% of his annual base salary, Board Members up to 100% and CFO to 50%. In order to adapt market references and new indicators, in 2020 the 20% readjustment in the previous target was approved, establishing observation parameters for the granting of shares or options, which vary between 12% and 180% of the eligible annual base salary, level hierarchical level and location.

The intent of such Program to attract and assure the long-term commitment of executives by allowing them to share in the growth of the Company, thereby enhancing the 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 Korn Ferry Consultancy, an expert in compensation related matters, reviewed the Long-Term Compensation Program in order to tie a significant part of this compensation to a long-term financial metric, in this case the ROCE (Return on Capital Employed), which was submitted to and approved by the Gerdau Compensation and Succession Committee during the meeting held on April 28, 2010. The Chief Executive Officer (CEO and Director positions 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.

In a shareholders meeting, held on September 19, 2013, changes to the Program were approved to better support the fulfillment of long-term goals. These changes consisted of the inclusion of new "vehicles" such as Restricted Shares, Performance Shares, Differed Shares and also allowed participants to convert voluntarily until November 17, 2013, their Stock Options or Share Appreciation Rights to Restricted Shares, through a calculation methodology that assured that there would be equivalent fair value.

On 12/18/2020, new amendments to the Long-Term Incentive Plan were approved at the Extraordinary General Meeting of Gerdau SA, which aim at aligning the long-term compensation incentives of senior leadership through performance goals that may be met. based on the economic-financial indicator EVA (Economic Value Added), and on sustainability indicators, which will consider a combination of indicators that are part of the SCORECARD ESG. There was also the inclusion of complementary programs such as ILP Matching and specific retention actions (ILP Spot).

**Corporate structure:** Gerdau's corporate structure has evolved to help the business, adding value in governance and brand, image and values, and optimizing the efficiency of Gerdau's activities through economies of scale. The corporate areas are Finance, Investor Relations and Accounting; Communication and Brand, Legal and Institutional Relations, Compliance, Internal Audit, Industrial, Engineering, Health, Safety and Environment, Information Technology and Procurement. In addition, the Shared Services area has the task of optimizing resources and achieving economies of scale.

All members of the Board of Directors and the Board of Executive Officers 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 Board of Officers 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 from the Board of Directors, 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) does not need to 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 a 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· have the authority to engage independent counsel and other advisors as deemed necessary, to carry out its duties; and

[**Table of Contents**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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 Bylaws 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.

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 of Directors 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 of Directors 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 the 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 a 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 a company's management. 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; and, also, 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 corresponding 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, elected at the Company's last Ordinary General Meeting of Shareholders:

**A. CONSOLIDATED STATEMENTS AND OTHER FINANCIAL INFORMATION**

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

**General**

In common with other Brazilian companies, Gerdau and its subsidiaries are parties to judicial and administrative proceedings involving labor, civil and tax matters. Management believes that the provisions recorded for these judicial and administrative proceedings are sufficient to cover probable and reasonably estimable losses from unfavorable court decisions and that the final decisions will not have significant effects on the financial position of the Company and its subsidiaries on December 31, 2022.

The following table summarizes the contingencies and related judicial deposits: as of December 31, 2022, 2021, and 2020 (in thousands of Reais):

The material administrative and judicial claims and the related provisions are described more fully in Note 19 to the Financial Statements.

**Tax Provisions**

Tax provisions are related to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● R$143,570 related to ICMS (state VAT), mostly in regarding of the right of offsetting credits.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● R$83,806 related to Social Security Contributions asset on the payroll.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● R$1,024 related to Recomposição Tarifária Extraordinária – RTE, which represent tariffs charged for supplying energy to the Company's industrial units. Management believes that these tariffs represent taxes and are thus incompatible with the National Tax System. The claims are currently under review in Regional and Superior Federal Courts. The Company has made escrow deposits equivalent to the total amount of these claims.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● R$617,460 related to disallowance of PIS and Cofins credits and claims related to their impact on other revenues.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● R$588,764 related to tax uncertainties related to Corporate Income Tax - IRPJ and Social Contribution on Net Income – CSLL.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● R$31,563 related to other taxes, which were classified as probable loss.

The Company and its subsidiaries are parties to other tax claims, described within this document on Item 3. D – Risk Factors. For these claims, no accounting provision was made, since these were considered as possible losses, based on the opinion of its legal counsel and management's assessment.

**Labor Provisions**

The Company is also a party to labor lawsuits, for which there is a provision of R$463.452 as of December 31, 2022. None of these lawsuits involve significant amounts individually and the lawsuits involve various labor amounts and the provision arises

[**Table of Contents**](#TOC)

from unfavorable decisions and/ or probability of probable loss in the normal course of claims with the expectation of outflow of financial resources by the Company. The balance of judicial deposits related to labor contingencies, on December 31, 2022, represented R$67.911.

The Company and its subsidiaries are parties to other labor claims that together have an amount of approximately R$820.032. For these claims, no accounting provision was made, since these were considered as possible losses, based on the opinion of management with input from legal counsel.

**Other Provisions**

The Company is also involved in lawsuits arising from the ordinary course of its operations and has reserved R$32.511 for these actions. Deposits in guaranteed accounts related to these contingencies on December 31, 2022, amounted to R$154.852.

Other contingent liabilities with remote probabilities of losses, involving uncertainties regarding their occurrence, and, therefore, not included in the contingency reserve, are composed of:

***Antitrust Proceedings***

A lawsuit arising from the request by 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 Competition Defense System (SDE — Secretaria de Direito Econômico), the final opinion was that a cartel exists. The lawsuit was therefore forwarded to the Administrative Council for Economic Defense (CADE) for judgment, which resulted in a fine to the Company and other long steel producers, on September 23, 2005, an amount equivalent to 7% of gross revenues in the year before the Administrative Proceeding was commenced, excluding taxes (fine of R$245,070, updated by the judicial accountant on August 01, 2013 to R$417,820).

Two lawsuits challenge the investigation conducted by the Competition Defense System based on procedural irregularities, especially the production of evidence, based on an economic study, to prove that a cartel did not exist. The Court, upon offer of bank guarantee letter, granted the suspension of the effects of CADE's decision. Both actions were dismissed, and their respective appeals were also rejected by the Federal Regional Court of the 1st Region. Against both decisions, appeals were lodged with the Superior Court of Justice and the Federal Supreme Court. The Appeal to the Federal Supreme Court was dismissed.

Upon unanimous decision, the Superior Court of Justice (STJ) dismissed the fine, acknowledging that there was not due legal process, considering that CADE conducted the case without the proper market analysis and related facts (see STJ, REsp 1.979.138 - DF (2021/0405949-3), Min. Benedito Gonçalves). The STJ decision is now the subject of appeal by CADE and the Company will continue to seek all legal remedies to defend its rights.

The Company denies having been engaged in any type of anti-competitive conduct.

***Other Civil Litigation***

The Company and its subsidiaries are parties to other civil claims that together have an amount of approximately R$552.515. For these claims, no accounting provision was made, since these were considered as possible losses, based on the opinion of its legal counsel and management's assessment.

**No Material Effect**

Management believes that any losses arising from other contingencies will not materially affect the results of operations or the Company's consolidated financial position. However, there is no guarantee that a final court order will be favorable in any of these or other proceedings, as well as any material adverse effects on the Company's consolidated financial position, results or future cash flows.

**Dividend Distribution** 

Brazilian Corporate Law generally requires the Bylaws of each Brazilian corporation to specify a minimum percentage of the profits for each fiscal year that must be distributed to shareholders as dividends. On this note, it is not uncommon for corporations to

[**Table of Contents**](#TOC)

provide for a minimum payout of 25% of adjusted net income. According to the Company's Bylaws, this percentage has been fixed at no less than 30% of the adjusted net income for distribution 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 financial institution providing the Company with custodial services ("Custodian") uses the significant 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, 2022, Gerdau S.A.'s legal reserve amounted to R$2,210.5 million or 11.5% of total paid-in capital of R$19,249.2 million.

According to Law 6,404, holders of preferred shares in a Brazilian corporation are entitled to dividends at least 10% greater than the dividends paid on ordinary shares. Gerdau S.A.'s executive directors presented a proposal at the 2002 shareholders' meeting to grant to both ordinary 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 (section 19 of the Company's Bylaws) 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 ordinary shares.

As a general requirement, shareholders who are non-residents of 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 American depositary shares ("ADSs") will be held in Brazil by the Custodian as agent for the Depositary Bank (the "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, are 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 ADSs. 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 ADSs 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 ADSs, are not subject to Brazilian withholding tax.

Since 1999, dividends have been paid to holders of the Company's ordinary and preferred shares in *reais* and in U.S. dollars converted from *reais* at the commercial exchange rate on the date of payment. Significant amounts are described in Item 3 - Key Information - Selected Financial Data.

***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.

**São Paulo Stock Exchange - Brasil**

***Trading on the B3***

The São Paulo Stock Exchange (called "B3 S.A. - Brasil, Bolsa, Balcão" or just "B3") trading is conducted between 10:00 a.m. and 5:00 p.m. *(or 6:00pm depending on the season)* on the B3 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 B3. The price variations are limited to 2% (above or below) the closing quote of the day.

In order to better control volatility, the B3 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 B3 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 B3's own discretion whenever the index of the B3 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 B3. The CVM and the B3 have discretionary authority to suspend trading in shares of a particular issuer under certain circumstances. Trading of securities listed on the B3 may be affected off the stock exchange market under certain circumstances, although such trading is very limited.

Settlement of transactions is affected 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 B3 by non-residents of Brazil is subject to certain limitations under Brazilian foreign investment legislation. See specific regulation for foreign investments in Brazil.

**Corporate Governance Practices in Brazil**

In 2000, the B3 introduced three special listing segments, known as Level 1 and 2 of Differentiated Corporate Governance Practices and in 2004 the *Novo Mercado*, aimed at encouraging Brazilian companies to follow good corporate governance practices and higher levels of transparency, as per 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 B3. 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; (vii) at least once a year, hold public meetings with analysts and investors; (viii) include in the Company' Bylaws of the mandatory minimum clauses set out by B3; (ix) prepare and publish its Trading Securities Policy and Code of Conduct; and (x) not accumulate the position of Chairman of the Board of Directors and Chief Executive Officer or lead executive by the same person.

[**Table of Contents**](#TOC)

**Regulation of the Brazilian Securities Market**

The Brazilian securities markets are regulated by the CVM, 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 No. 6,385 of December 7, 1976, as amended) and the Brazilian Corporate Law (Law No. 6,404 of December 15, 1976, as amended).

Law No. 11,638, of December 28, 2007, and Law No. 11,941, of May 27, 2009, amended a number of provisions of Law No. 6,385/76 and Law No. 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 B3 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, dated as 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. CVM Instruction N. 480/09 significantly modified the reporting requirements applicable to publicly held companies and set forth the obligation to such companies to file annually with CVM a Reference Form ("Formulário de Referência") containing all of the Company's significant information and to update the information contained therein as soon as any significant changes occur.

In addition to such reporting requirements, the occurrence of certain events also requires disclosure of information to the CVM, the B3, 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.

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 a company's respective intermediaries. The trading of a company's securities on the B3 may be suspended in anticipation of a material announcement. Trading may also be suspended at the initiative of the B3 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 No. 4,131/62 and CMN (*Conselho Monetário Nacional*) Resolution N. 3,844/10 or as a portfolio investment under CMN Resolution N. 4,373/14 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 No.1,863, as of December 27, 2018. This registration process is undertaken by the investor's legal representative in Brazil.

Law No. 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

[**Table of Contents**](#TOC)

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. 4,373/14 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 ordinary 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. 4,373/14.

Securities and other financial assets held by non-Brazilian investors pursuant to CMN Resolution N. 4,373/14 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 B3, 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 ADSs, which began trading on the New York Stock Exchange the same day. Under the GGB symbol, these Level II ADSs have been traded in virtually every session since the first trading day. In 2022, 3.5 billion ADSs were traded, being a volume 20.7% higher than 2021 and representing a trading volume of US$19.74 billion, equivalent to a daily average of US$78.3 million. In 2021, 2.9 billion ADSs were traded, a figure 35% higher than in 2020, representing a trading volume of US$16.17 billion, equivalent to a daily average of US$64.2 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 2021, a total of 90 thousand Gerdau preferred shares were traded on the Madrid Stock Exchange (Latibex), representing a trading volume of $2.16 million, equivalent to a daily average of $1.8 thousand.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**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 significant investment with the Central Bank of Brazil.

In Brazil, a mechanism is available to foreign investors interested in trading directly on the B3 which is regulated by CMN Resolution N. 4,373/14 and CVM Resolution N. 13/20.

CMN Resolution N. 4,373/14 establishes rules for foreign investments in Brazilian equities. Such rules allow foreign investors to invest in almost all types of financial assets 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. 4,373/14, foreign investors are defined as individuals, legal entities, mutual funds and other collective investments resident, domiciled or headquartered abroad. CMN Resolution N. 4,373/14 prohibits the offshore transfer or assignment of title to the securities.

Pursuant to CMN Resolution N. 4,373/14, foreign investors must: (i) appoint at least one representative in Brazil with powers to perform actions relating to the foreign investment; (ii) obtain registration as a foreign investor with the CVM; (iii) appoint an authorized custodian in Brazil for its investment; and (iv) register the foreign investment with the Central Bank. The securities and other financial assets held by the foreign investor pursuant to CMN Resolution N. 4,373/14 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 is 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. 4,373/14 will be subject to electronic registration with the Central Bank.

CMN Resolution N. 4,373/14 provides for the issuance of depositary receipts in foreign markets in respect of shares of Brazilian issuers. Since ADSs have been approved under the applicable law by the Central Bank and the CVM, the proceeds from the sale of the ADSs by ADS holders outside Brazil are free of Brazilian foreign investment controls and holders of the ADSs will be subject to a specific tax treatment. According to CMN Resolution N. 4,373/14, are subject to concurrent exchange operations or international transfers in Brazilian Reais, without effective delivery of resources and whether prior authorization of the Central Bank

[**Table of Contents**](#TOC)

of Brazil, the application of non-resident investor through the mechanism of Depositary Receipts may be transferred to other foreign investments mechanisms, with due regard to the conditions set forth by the Central Bank and by the CVM.

CVM Resolution 13/2020 exempted the individual foreign investor from obtaining registration with CVM, requires that his representative send, prior to the start of operations, the information requested in an electronic system made available by CVM or by the organized market administrator that has formalized a partnership or similar instrument with CVM for this purpose. The representative of the foreign investor may be an intermediary institution through which the investor operates in the Brazilian exchange market. This resolution started on May 2, 2022.

Since July 1, 2013, JPMorgan Chase Bank is the Depositary for the ADSs ("Depositary") and Itaú Unibanco 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 ADSs into foreign currency and remit the proceeds abroad. Subject to the provisions set forth in Annex V Regulations, holders of preferred ADSs may exchange such ADSs 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 ADSs will be the U.S. dollar equivalent to (i) the average price of the Preferred Shares on the B3 on the day of withdrawal, or (ii) if no 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 N. 4,373/14 or to Law No. 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 ADSs.

Restrictions on the remittance of foreign capital overseas could hinder or prevent the Custodian, as custodian for the Preferred Shares represented by ADSs, or holders who have exchanged ADSs 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 ADSs 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 ADSs.

**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.

On December 29, 2021, Law No. 14.286 was sanctioned, creating transactions where payments with international currency will be allowed in Brazil, and allowing banks and financial institutions to invest, allocate or lend resources in Brazil or abroad while

[**Table of Contents**](#TOC)

facilitating the use of Brazilian currency in international transactions. The law provides the creating of further specific regulation and entered into force on December 30, 2022.

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 main Brazilian and U.S. federal income tax consequences of the purchase, ownership and disposition of common shares, Preferred Shares and ADSs, as applicable. It does not purport to be a comprehensive description of all tax considerations that may be significant to a decision to purchase these securities. In particular, this summary only addresses holders of common shares, Preferred Shares or ADSs 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, 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 total combined voting power of the Company's voting stock or 10% or more of the total value of the Company's stock, and investors that hold the common shares, Preferred Shares or ADSs as part of a straddle, hedge, conversion or constructive sale transaction or other integrated transaction. Prospective purchasers of common shares, Preferred Shares or ADSs should consult their own tax advisors as to the personal tax consequences of their 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. Such 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 authorities of the two countries continue to have 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 U.S. holders of Preferred Shares or ADSs. This summary is also based on the representations of the Depositary (as defined below) and under the assumption that each obligation in the Deposit Agreement relating to the ADSs and any related documents will be performed in accordance with its specific terms.

**Brazilian Tax Considerations**

The following information summarizes the main Brazilian tax consequences related to the acquisition, ownership and disposition of common shares, Preferred Shares or ADSs by a holder that is not resident or domiciled in Brazil for tax purposes ("Non-Resident Holder").

The following is a general discussion only and does not specifically address all of the Brazilian tax considerations applicable to any particular Non-Resident Holder. The effects of any tax treaties or reciprocity of tax treatment entered into by Brazil and other countries are not addressed herein, nor are any tax consequences applicable under the laws of Brazilian States and Municipalities.

***Income tax***

*Dividends*

Dividends derived from profits generated on or after January 1, 1996, 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 ADSs, are currently exempt from income tax in Brazil, as provided by art. 10 of Federal Law no. 9,249, of December 26, 1995.

Despite the fact that this exemption is currently in force, news released by the press in past years claim that the Brazilian authorities intend to revoke the mentioned tax exemption and thus levy income tax on dividends paid by Brazilian companies, a measure that allegedly would be followed by a reduction of the overall income tax burden borne by said companies. Currently, several bills on the subject are being discussed and await voting in the Brazilian National Congress. These bills have not advanced during the year of 2021 as a result of the inherent complexity of the subject matter and the pandemic caused by the COVID-19, nor in 2022, year

[**Table of Contents**](#TOC)

when the last presidential elections took place. Nonetheless, it is possible that there are developments in 2023; as a matter of fact, the new Federal Government, which took office in January 1, 2023, promised promoting a broad tax reform, which would include the rules pertaining to the taxation of income (in the framework of which are included the rules for the taxation of dividends). In any case, it is not yet possible to anticipate the exact terms of the intended taxation, and such new taxation rules would only become effective as of January 1, 2024, at the earliest, if approved by the Brazilian National Congress in 2023.

*Interest Attributable to Shareholders' Equity*

As from the enactment of Federal Law no. 9,249/95, a Brazilian corporation, such as our company, is allowed 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 calculated over the net equity accounts of the corporation and is limited to the daily *pro rata* variation of the Brazilian long-term interest rate (*Taxa de Juros de Longo Prazo –* "TJLP"), as determined by the Brazilian Central Bank from time to time, and the amount of the deduction cannot exceed the greater of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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.

Such payments of interest on shareholders' equity made to a Non-Resident Holder are generally subject to withholding income tax at the rate of 15%, being such rate increased to 25% if the Non-Resident Holder is resident or domiciled in a Tax Favorable Jurisdiction (please refer to "—Tax Favorable Jurisdictions" for a definition of this concept).

Payments of interest on shareholders' equity may be included, at their net value, as part of any mandatory dividend. To the extent a 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 such shareholders, after payment of the applicable withholding income tax, plus the amount of declared dividends, is at least equal to the mandatory dividend ("gross-up method").

Although the Brazilian legislation currently in force allows payments of interest on shareholders' equity, news released by the press also claim that the Brazilian authorities are considering revoking such incentive, in the framework of the mentioned tax reform – a measure that would be followed by a reduction of the overall income tax burden borne by said companies, as mentioned above.

Be it as it may, in case these new rules concerning the payment of interest on net equity are enacted throughout the course of this year, they would become effective as of January 1, 2024, at the earliest.

*Capital Gains*

According to Federal Law no. 10,833, of December 29, 2003, gains deriving from the transfer 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.

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

As far as ADSs are concerned, although the matter is not entirely clear, arguably the gains realized by a Non-Resident Holder on the disposition of ADSs are not taxed in Brazil, based on the argument that ADSs are not "assets located in Brazil" for purposes of Article 26 of Federal Law no. 10,833/03. We cannot assure you, however, that Brazilian tax authorities or Brazilian tax courts will agree with this interpretation. Accordingly, in the event that ADSs are deemed to be "assets located in Brazil" for purposes of Article 26 of Federal Law no. 10,833/03, gains realized on a disposition of ADSs by a Non-Resident Holder will be subject to withholding income tax in Brazil, according to the rules described below.

[**Table of Contents**](#TOC)

In general, gains realized on the disposition of common or preferred shares (or ADSs, in case they are deemed to be "assets located in Brazil") correspond to the positive difference between the amount ascertained on the disposition, and the acquisition cost of the shares disposed of, assessed in Brazilian *reais* (without any correction for inflation), in line with the views expressed by the Brazilian tax authorities on the matter (*see, e.g.,* Normative Ruling no. 1,455, issued on March 06, 2014). There are grounds, however, for maintaining that the gains realized should be calculated taking into consideration the cost of the significant investments in foreign currency, as so registered before the Brazilian Central Bank. Notwithstanding, no assurance can be provided as to whether such arguments will prevail in the Brazilian administrative and/or judicial courts.

The rules related to whether or not withholding income tax must be levied on such gains will vary depending on the domicile of the Non-Resident Holder, the type of registration of the investment that must be made by the Non-Resident Holder before the Brazilian Central Bank, and how the disposition is carried out.

Gains realized on a disposition of common or preferred shares carried out on the Brazilian stock exchange are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· exempt from income tax when assessed by a Non-Resident Holder that (1) has invested in Brazil under the rules set forth by the Brazilian Central Bank – " Qualified Portfolio Investor " (in particular the National Monetary Council Resolution no. 4,373, of September 29, 2014) and (2) is not domiciled or resident in a Tax Favorable Jurisdiction. Please refer to "— Tax Favorable Jurisdictions " for a definition of this concept; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· 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 Qualified Portfolio Investor, and of a Non-Resident Holder that is domiciled or resident in a Tax Favorable 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 realized by a Non-Resident Holder on a disposition of common shares or Preferred Shares (or ADSs, in case they are deemed "assets located in Brazil") that is not carried out on a Brazilian stock exchange are subject to income tax at the same rate applicable to resident individuals. As from January 1, 2017, in accordance with Article 21 of Federal Law no. 8,981, of January 20, 1995, as amended by Federal Law no. 13,259, of March 16, 2016, capital gains realized by resident individuals are taxable at progressive rates in brackets that vary from 15% to 22,5%, depending upon the amount of gain realized on the transaction, being: (i) 15% on gains realized up to R$5 million; (ii) 17,5% on gains exceeding R$5 million but not R$10 million; (iii) 20% on gains exceeding R$10 million but not R$30 million; and (iv) 22,5% on gains exceeding R$30 million. In case, however, the Non-Resident Holder is resident or domiciled in a Tax Favorable Jurisdiction, the gains he/she realizes upon disposition of said assets will be taxable at the fixed rate of 25% (please refer to "—Tax Favorable Jurisdictions" below for a definition of this concept).

Gains related to transactions carried out outside the Brazilian stock exchanges, but on a Brazilian over-the-counter market with intermediation, are also subject to the withholding income tax of 0.005%, which can be offset against income tax due on any capital gain realized on the transaction.

In the event of a redemption of common shares or Preferred Shares (or ADSs, 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 shares or Preferred Shares (or ADSs, 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 income tax at a rates described in the previous paragraphs.

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

A Non-Resident Holder of ADSs may cancel such ADSs 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 before the Brazilian Central Bank, and as long as ADSs are not deemed "assets located in Brazil".

The deposit of common or preferred shares by a Non-Resident Holder in exchange for ADSs may trigger Brazilian income tax on the capital gain presumably realized, in accordance with the rates mentioned above. There are grounds to maintain, 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 before the Brazilian Central Bank.

[**Table of Contents**](#TOC)

There can be no assurance that the current favorable tax treatment granted to Qualified Portfolio Investors will continue in the future.

***Tax Favorable Jurisdictions***

The concept of "Tax Favorable Jurisdiction" is defined by Federal Law 9,430, of December 27, 1996, and included the countries or locations (1) that do not impose income tax, (2) where the maximum income tax rate is lower than 20% (such percentage may be reduced or restored by the Executive branch) or (3) whose laws 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. Normative Ruling no. 1,037, of June 04, 2010, expressly lists the countries or locations that fit into such definition.

The same Federal Law no. 9,430/96, as amended by Federal Law no. 11,727, of June 23, 2008, also sets forth the concept of "Privileged Tax Regimes"; said regimes are also expressly listed by Normative Ruling no. 1,037/10. Notwithstanding, the mentioned concept does not seem significant for purposes of determining the tax treatment applicable to investments made by Non-Resident Holders of common shares, Preferred Shares and ADSs, although one cannot completely disregard the risk that tax authorities argue otherwise.

Ordinance (*"Portaria"*) no. 488, issued by the Brazilian Ministry of Finance on November 28, 2014, lowered the tax threshold at which countries or locations are deemed to be "Tax Favorable Jurisdictions" (*see* item (2), above), from 20% to 17%.

***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 Brazilian *reais* into foreign currency and on the conversion of foreign currency into Brazilian *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 Articles 15-B and 15-C of Decree no. 6,306, of December 14, 2007, 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 currently subject to IOF/FX at a zero percent rate.

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.

The Brazilian government is permitted to increase the rate of the IOF/FX at any time 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 is levied at the rate of 0% in most transactions involving common or preferred shares, including 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 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 Federal Brazilian inheritance, gift or succession taxes applicable to the ownership, transfer or disposition of common shares, Preferred Shares or ADSs, 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 shares, Preferred Shares or ADSs.

**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 ADSs by a U.S. holder (as defined below) holding such shares or ADSs 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 address federal tax laws other than those pertaining to U.S. federal income taxation (such as estate or gift tax laws), nor does it address any aspects of U.S. state or local or non-U.S. 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 significant to a U.S. holder of a Preferred Share or ADS, 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 total combined voting power of the Company's voting stock or 10% or more of the total value of the Company's stock, investors that hold the Preferred Shares or ADSs 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 ADS 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 for U.S. federal income tax purposes) 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 ADS 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 ADS, 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 ADS 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 ADSs.

***Nature of ADSs 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 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 an ADS 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 ADSs will be the same for Preferred Shares in the Company, and exchanges of Preferred Shares for ADSs, and ADSs 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 ADSs, unless otherwise noted.

[**Table of Contents**](#TOC)

***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 it is made from the Company's current or accumulated "earnings and profits" as determined under U.S. federal income tax principles (regardless of whether it is considered a dividend under Brazilian law or for Brazilian income tax purposes). If a distribution exceeds the amount of the Company's current and accumulated earnings and profits, it will be treated as a non-taxable return of capital (and reduction in tax 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 from the sale or exchange of the Preferred Shares. 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 any distribution on a Preferred Share generally will be treated as a dividend for U.S. federal income tax purposes even if that distribution would otherwise be treated as a non-taxable return of capital or as capital gain under the rules described above.

The gross amount of any dividend on a Preferred Share (which will include the amount of any Brazilian taxes withheld, if any) 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 an ADS, 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 an ADS, 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 Brazilian currency. 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 generally will be subject to a maximum Federal income tax rate of 20% (plus an additional 3.8% Net Investment Income tax — see *"Net Investment Income Tax"*) 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 ADSs 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 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. holders of Preferred Shares are urged to consult their own tax advisers regarding the availability of the reduced qualified 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"

[**Table of Contents**](#TOC)

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 31-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 by whom ADSs are held or to whom they are transferred may be taking actions that are inconsistent with the claiming of foreign tax credits by U.S. holders of ADSs. Accordingly, the discussion above regarding the credibility of Brazilian withholding taxes could be affected by future actions that may be taken by the IRS.

***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 tax 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 long-term net capital gain of a non-corporate U.S. holder is subject to a maximum U.S. Federal income tax rate of 20% (plus an additional 3.8% Net Investment Income tax — see *"Net Investment Income Tax"*). 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 claiming a foreign tax credit for any Brazilian income tax withheld on U.S. source capital gain from a sale of a Preferred Share as an offset against the U.S. federal income tax liability on such U.S. source gain. Alternatively, any Brazilian withholding tax may be taken as (i) a foreign tax credit to offset U.S. federal income tax on non-U.S. source income or gains that the taxpayer has in the same "basket" of income, or (ii) 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 are met. Any effectively connected gain of 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.

***PFIC Rules***

A special set of U.S. federal income tax rules applies to a foreign corporation that is PFIC for U.S. federal income tax purposes. Based on the Company's audited financial statements and significant 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 taxable year, nor does it anticipate being classified as a PFIC in its current taxable year or future taxable years. However, because

[**Table of Contents**](#TOC)

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 significant 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) will generally be subject to adverse U.S. federal income 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 for non-corporate taxpayers. 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.

***Net Investment Income Tax***

A U.S. holder that is an individual or estate, or a trust that does not fall into a special class of trusts that is exempt from such tax, will be subject to a 3.8% tax on the lesser of (1) the United States holder's "net investment income" (or undistributed "net investment income" in the case of estates and trusts) for the significant taxable year and (2) the excess of the United States holder's modified adjusted gross income for the taxable year over a certain threshold (which in the case of individuals will be between $125,000 and $250,000, depending on the individual's circumstances). A holder's net investment income will generally include its dividend income and its net gains from the disposition of the Preferred Shares, unless such dividend income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). If you are a U.S. holder that is an individual, estate or trust, you are urged to consult your own tax advisor regarding the applicability of this Net Investment Income tax to your income and gains in respect of your investment in our Preferred Shares.

***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, U.S. holders that hold certain specified foreign financial assets in excess of $50,000 are subject to U.S. return disclosure obligations (and related penalties for failure to comply with such reporting requirements). 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 non-U.S. 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 24%) unless the U.S. holder provides an accurate taxpayer identification number or otherwise demonstrates that it is exempt from backup withholding. 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 non-U.S. status.

| **ITEM 11.** | **QUANTITATIVE AND QUALITATIVE DISCLOSURES REGARDING MARKET RISK** |

---

Gerdau is exposed to various market risks, which involve the fluctuation of exchange rates, interest rates and also commodities. The Company uses derivatives and other financial instruments to reduce the impact of such risks on its financial assets and liabilities or future cash flows and earnings. Gerdau has established policies to assess market risks and to approve the use of derivate financial instruments transactions related to those risks. The Company enters into derivative financial instruments to manage the above-mentioned market risks and never for speculative purposes.

**Exchange Rate Risk**

This risk is related to the possibility of fluctuations in exchange rates affecting the amounts of financial assets or liabilities or of future cash flows and income. The Company assesses its exposure to the exchange rate by measuring the difference between the amount of its assets and liabilities in foreign currency. The Company understands that the accounts receivables originated from exports, its cash and cash equivalents denominated in foreign currencies and its investments abroad are more than equivalent to its liabilities denominated in foreign currency. Since the management of these exposures occurs at each operation level, if there is a mismatch between assets and liabilities denominated in foreign currency, the Company may contract derivative financial instruments in order to mitigate the effect of exchange rate fluctuations.

**Foreign currency sensitivity analysis**

As of December 31, 2022, the Company is mainly exposed to variations between the Real and the Dollar. The sensitivity analysis carried out by the Company considers the effects of a 5% increase or decrease between the Real and the Dollar in its non-hedged debts, trade accounts receivable - exports from Brazil and trade accounts payable - imports (also including the variation between the Argentinian Peso and the Dollar). In this analysis, if the Real/Argentinian Peso appreciates against the Dollar, this would represent a gain of R$113,778 (R$19,036 as of December 31, 2021). If the Real/Argentinian Peso depreciates against the Dollar, this would represent an expense of the same amount.

The net values of other assets and other liabilities in foreign currencies do not present significant risks of impacts due to fluctuations in the exchange rate.

**Interest rate risk**

This risk arises from the effects of fluctuations in interest rates applied to the Company's financial liabilities or assets and future cash flows and income. The Company evaluates its exposure to these risks: (i) comparing financial assets and liabilities denominated at fixed and floating interest rates and (ii) monitoring the variations of interest rates like SOFR and CDI. Accordingly, the Company may enter into interest rate swaps in order to reduce this risk.

[**Table of Contents**](#TOC)

***Interest rate sensitivity analysis***

The interest rate sensitivity analysis made by the Company considers the effects of an increase or reduction of 10 basis point (bps) on the average interest rate applicable to the floating part of its debt. The calculated impact, considering this variation in the interest rate totals R$32,377 as of December 31, 2022 (R$55,964 as of December 31, 2021) and would impact the Financial expenses account in the Consolidated Statements of Income. The specific interest rates to which the Company is exposed are related to the loans, financing, and debentures presented in Notes 15 and 16, and are mainly comprised by SOFR and CDI — Interbank Deposit Certificate.

**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 operates in a commodity market, net sales 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. Besides that, the Company may use derivative instruments for hedge purposes.

The Company is exposed to changes in the price of its products. This exposure is associated with the fluctuation of the sale price of the Company's products and the price of raw materials and other inputs used in the production process, mainly for operating in a commodity 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, considering the revenues and costs for the year ended on December 31, 2022, totals R$824,122 (R$783,751 as of December 31, 2021) and the variation in the price of raw materials and other inputs totals R$486,066 as of December 31, 2022 (R$437,210 as of December 31, 2021). The impact in 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.

**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 adopt the procedure of analyzing in details of the financial position of their customers, establishing a credit limit and constantly monitoring their balances. Regarding financial investments, the Company only carries out transactions with first-rate institutions and with low credit risk, as assessed by rating agencies and risk mitigation parameters defined in the Company's internal guidelines.

The Company is monitoring the spread of COVID-19, commonly known as coronavirus, throughout the many countries in which it operates. The COVID-19 virus continues to impact worldwide economic activity and pose the risk that customers and other business partners may be prevented from conducting certain business activities for an indefinite period of time, including due to shutdowns that may be requested or mandated by governmental authorities or otherwise elected by companies as a preventive measure. In addition, mandated government authority measures or other measures elected by companies as preventative measures may lead to our customers being unable to complete purchases or other activities. COVID-19 may have an adverse effect on trading and our operations and, given the uncertainty around the extent and timing of the potential future spread or mitigation and around the imposition or relaxation of protective measures, we cannot reasonably estimate the impact to our future results of operations, cash flows or financial condition.

**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) based on internal policies and benchmarks. The Key Performance Indicators (KPI) related to the "Capital Structure Management" objective are: WACC (Weighted Average Cost of Capital), Net Debt/EBITDA (Earnings before interest, income tax, depreciation and amortization), Coverage Ratio of Net Financial Expenses (EBITDA/Net Financial Expenses) and Debt/Total Capitalization Ratio. Net Debt is formed by the principal of the debt reduced by cash, cash equivalents and short-term investments (Notes 4, 15 and 16). Total Capitalization is formed by the Total Debt (composed of the principal of the debt) and the Equity (Note 24). The Company may change its capital structure, according to economic and financial conditions, in order to optimize its financial leverage and debt management. At the same time, the Company

[**Table of Contents**](#TOC)

seeks to improve its ROCE (Return on Capital Employed) through the implementation of working capital management and an efficient program of investments in property, plant and equipment.

**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.

On March 10, 1999, Gerdau S.A. obtained registration for the issuance of Level II ADSs, which began trading on the New York Stock Exchange the same day. Under the GGB symbol, these Level II ADSs are equivalent to one preferred share of Gerdau S.A (GGBR4).

J.P. Morgan Chase Bank, as depositary, has agreed to reimburse the Company for expenses it incurs that are related to the maintenance of the ADS program. The depositary has agreed to reimburse the Company for its continuing and annual stock exchange listing fees. It has also agreed to pay the standard out-of-pocket maintenance costs for the ADSs, and to reimburse the Company annually for certain investor relations programs or special promotional activities. In certain instances, the depositary has agreed to provide additional payments to the Company based on any applicable performance indicators relating to the ADS facility. There are limits on the amount of expenses for which the depositary will reimburse the Company, but the amount of reimbursement available to the Company is not necessarily tied to the amount of fees the depositary collects from investors. During calendar year 2022, the depositary reimbursed the Company in the amount of US$1,206,413 gross (US$844,489 net of withholding taxes).

The depositary collects its fees for delivery and surrender of ADSs directly from investors depositing shares or surrendering ADSs for the purpose of withdrawal or from intermediaries acting for them. The depositary collects fees for making distributions to investors by deducting those fees from the amounts distributed or by selling a portion of distributable property to pay the fees. The depositary may collect its annual fee for depositary services by deduction from cash distributions or by directly billing investors or by charging the book-entry system accounts of participants acting for them.

The fees that ADS holders may be required to pay or incur are the following:

**(a) Disclosure Controls and Procedures**

The Company has established disclosure controls and procedures to ensure that the information required to be disclosed by the Company in the reports that it files or submits under the Securities Exchange Act of 1934 as amended (the "Exchange Act") is recorded, processed, summarized and reported within the time periods specified in SEC rules and forms. And such information is accumulated and made known to the officers who certify the Company's financial reports and to other members of senior management and the Disclosure Committee as appropriate to allow timely decisions regarding required disclosure.

A control system, no matter how well designed and operated, can only provide reasonable, not absolute, assurance that the objectives of the control system will be met. Based on their evaluation as of December 31, 2022, the Chief Executive Officer and the Chief Financial Officer of the Company have concluded that the Company's disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended) are effective at a reasonable assurance level.

The Disclosure Committee is composed of the Chief Executive Officer, Gustavo Werneck, the Chief Financial Officer and Executive Vice President, Rafael Dorneles Japur, the Accounting Director, Clemir Uhlein, the Head of Corporate Communication, Pedro Torres Pinto and the Legal Director, Fabio Eduardo Spina. 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.

There have been no significant changes in the Company's internal control or other factors that could significantly affect these controls subsequent to the date of their most recent evaluation.

Please see Exhibits 12.01 and 12.02 for the certifications required by this Item.

**(b) Management's annual report on internal control over financial reporting**

The management of Gerdau S.A. is responsible for establishing and maintaining adequate internal control over Financial Reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934. The internal controls are designed 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. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management has documented and evaluated the effectiveness of the internal control over Financial Reporting of the Company as of December 31, 2022, in accordance with the criteria established in the Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). Based on the above evaluation, management has concluded that the Company maintained effective internal control over financial reporting as of December 31, 2022.

---

The Gerdau Code of Ethics and Conduct is the foundation that defines the Company's behavior and shows the commitment of conducting business ethically, which permeates the actions and relationships with employees, vendors, customers, shareholders and the community.

The Gerdau Code of Ethics and Conduct must be followed by all employees, Officers, President and Board of Directors, and meets all legal, ethics and compliance requirements applicable to publicly traded companies.

The current code is defined according to the Company's culture and the principle DO WHAT IS RIGHT. The code is organized with the chapters: safety above all; respect; obligation with third parties; conflict of interest; corruption prevention; laws and regulations; competition practices; accurate information; donation and sponsorship; protection of company property; data protection; disciplinary procedures; ethics helpline.

The code in the chapter "ethics helpline" instructs all to report suspected breaches or violations, with no fear of demotion, reprisal or retaliation. The Company has implemented an Ethics Helpline to which all employees and third parties may refer in the case of violations of the code, assuring confidentiality, anonymity, investigation of all cases, two-way communication for any needed follow-up and report of status to Risk Committee, Fiscal Council and Board of Directors.

The purpose and the contents of the current Code of Ethics and Conduct have been made public to all employees and board of directors, with their understanding and formal agreement, and have been the object of periodically in-company training. For suppliers, service providers and customers there is a Code of Ethics and Conduct with similar content.

The actual Code of Ethics and Conduct 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 incorporated by reference into this Annual Report 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.

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´s 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 Board of Auditors that consists of three but up to five members and three but up to five alternates and which has ordinary meetings every two months. The members of Gerdau S.A.'s Board of Auditors 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 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

[**Table of Contents**](#TOC)

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. As required by Brazilian law, members of the Board of Auditors must be college graduates or have held office for at least 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.

On December 14, 2021, the Board of Directors and Audit Committee of the Company approved the engagement of PricewaterhouseCoopers Auditores Independentes ("PwC") as its principal accountants for the fiscal year ending December 31, 2022, and will dismiss KPMG Auditores Independentes ("KPMG"), which served as the Company's independent auditors, upon completion of their audit of the consolidated financial statement as of December 31, 2021 and for the three years ended December 31, 2021 and the effectiveness of internal control over financial reporting as of December 31, 2021, and the issuance of their report thereon.

During the two fiscal years ended December 31, 2021, and the subsequent interim period through March 30, 2022, there were no: (1) disagreements with KPMG on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements if not resolved to their satisfaction would have caused them to make reference in connection with their opinion to the subject matter of the disagreement, or (2) reportable events.

The audit reports of KPMG on the consolidated financial statements of Gerdau and subsidiaries as of and for the years ended December 31, 2021 and 2020 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles.

During the fiscal years ended December 31, 2021, and 2020, and the subsequent interim through March 30, 2022, neither Gerdau S.A. nor anyone acting on its behalf has consulted with PwC regarding (1) the application of accounting principles to a specific transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company's financial statements or the effectiveness of internal control over financial reporting, and neither a written report or oral advice was provided to the Company that PwC concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue; (2) any matter that was the subject of a disagreement within the meaning of Item 16F(a)(1)(iv) of Form 20-F; or (3) any reportable event within the meaning of Item 16F(a)(1)(v) of Form 20-F.

| **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 the practices in Brazil in lieu of the provisions of the Corporate Governance Rules, except that it is 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 currently does not have a majority of independent directors serving on its board of directors (3 independent members out of 7 total members).

[**Table of Contents**](#TOC)

**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, but it is not 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; evaluating the recommendations of the agents of capital markets and financial and specialized agencies, to recommend to the Board principles and guidelines of Corporate Governance; reviewing and commenting on the information relating to Corporate Governance contained in the official documents of the Company for dissemination to the market and evaluating the performance of the Board as a whole.

**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 Compensation Committee to advise the full Board on employee and executive compensation and recruitment, incentive-compensation plans and related matters, but, although such committee has a separate charter, it is not composed by a majority of independent directors.

**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. 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 establishes operating principles for governance, and it observes the requirements of the Brazilian Securities Commission (CVM) and it has adhered to the Level I listing standards of the B3. Furthermore, Gerdau S.A. also has the following corporate policies: (i) Securities Trading Policy; (ii) Related-Party Transactions Policy; (iii) "Information Disclosure Policy ;(iv) Risk Management Policy; (v) Compliance Policy; (vi) Sustainability Policy; (vii) Anti-Corruption Policy; (viii) Human Rights Policy; (ix) Tax Policy ; (x) Integrated Policy; and (xi) Code of Ethics and Conduct.

**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 and in its submissions to the U.S. Securities and Exchange Commission.

**Report of Independent Registered Public Accounting Firm (include PwC report)**

To the Board of Directors and Shareholders of Gerdau S.A.

**Opinions on the Financial Statements and Internal Control over Financial Reporting**

We have audited the accompanying consolidated balance sheet of Gerdau S.A. and its subsidiaries (the "Company") as of December 31, 2022, and the related consolidated statements of income, comprehensive income, changes in equity and cash flows for the year ended December 31, 2022, including the related notes (collectively referred to as the "consolidated financial statements"). We also have audited the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in *Internal Control - Integrated Framework* (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2022, and the results of its operations and its cash flows for the year ended December 31, 2022, in conformity with International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB). Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2022, based on criteria established in *Internal Control - Integrated Framework* (2013) issued by the COSO.

**Basis for Opinions**

The Company's management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management's Annual Report on Internal Control over Financial Reporting appearing under Item 15(b). Our responsibility is to express opinions on the Company's consolidated financial statements and on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audit of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinions.

**Definition and Limitations of Internal Control over Financial Reporting**

A company's internal control over financial reporting is a process designed 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 (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) 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 (iii) 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.

[**Table of Contents**](#TOC)

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

**Critical Audit Matters**

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

**Goodwill Impairment Assessment**

As described in Notes 2.8, 11 and 30 to the consolidated financial statements, the Company has a consolidated goodwill balance of R$11,634,464 thousand as of December 31, 2022 and the goodwill balance associated with the with the North America and Special Steel cash generating units ("CGUs") were R$7,417,015 thousand and R$3,844,314 thousand, respectively. Management performs impairment tests of goodwill for each of its CGUs at least annually, or whenever changes in events or circumstances indicate that the carrying value of goodwill may be impaired. When the carrying amount of the asset exceeds its recoverable amount, the Company recognizes an impairment charge. The recoverable amount is the higher of fair value less costs of disposal and value in use. The Company's management determined the recoverable amount based on value in use, using a discounted cash flow model. The cash flow projections used by management to estimate the recoverable amount of goodwill includes significant judgments and assumptions relating to growth rates and discount rates.

The principal considerations for our determination that performing procedures relating to goodwill impairment assessment is a critical audit matter are the significant judgments by management when developing the recoverable amounts of the Company's CGUs. This, in turn, led to a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating management's significant assumptions, including growth and discount rates. In addition, the audit effort involved the use of professionals with specialized skill and knowledge to assist in performing these procedures and evaluating the audit evidence obtained.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to management's impairment assessment. These procedures also included, among others, testing management's process for developing a reliable estimate; evaluating the appropriateness of the discounted cash flow model; testing the completeness and accuracy of underlying data used in the model; and evaluating the reasonableness of the significant assumptions used by management related to discount and growth rates by considering (i) the current and past performance of the cash generating units, (ii) the consistency with available external market and industry data, and (iii) whether these assumptions were consistent with evidence obtained in other areas of the audit. Professional with specialized skill and knowledge were used to assist in the evaluation of the Company's use of the discounted cash flow model and the discount rate assumption.

**Recoverability of deferred tax assets**

As described in Notes 2.10 and 8 to the consolidated financial statements, the Company has a net amount of R$2,068,136 thousand of deferred tax credits ("IRPJ and CSLL") in its consolidated balance sheet as of December 31, 2022. The assessment of the recoverability of these deferred tax assets is dependent on the generation of future taxable income, which is supported by projections prepared by management. These assessments consider the historical profitability of the Company and its subsidiaries, expectations of continuous profitability and estimates of the recovery of deferred tax assets over future years. The future taxable income projections used by management to estimate the recoverability of these deferred tax assets includes significant judgments and assumptions relating to growth rates and discount rates as well as movements in the temporary tax differences.

The principal considerations for our determination that performing procedures relating to the recoverability of deferred tax assets is a critical audit matter are ; (i) a high degree of auditor judgment, subjectivity in applying our procedures relating to the reasonableness of the estimated recoverability of deferred tax assets through the assessment of the Company's ability to generate sufficient future taxable income; (ii) assessing the significant judgments and assumptions; and (iii) professionals with specialized skills and knowledge were used to assist in performing these procedures and evaluating the audit evidence.

[**Table of Contents**](#TOC)

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the completeness, accuracy and integrity of the tax data, significant assumptions and the future taxable income used to assess the recoverability of deferred tax assets. These procedures also included, among others, (i) evaluating the reasonableness of management's assessment of future taxable income generation; (ii) testing the completeness and accuracy of tax loss carryforwards and temporary tax differences, (iii) evaluating the appropriateness of the valuation method and the reasonableness of the projection for the recoverability of deferred tax assets; and (iv) evaluating the completeness, accuracy and sufficiency of disclosures. Professional with specialized skill and knowledge were used to assist in the evaluation of the tax calculation bases.

We have audited the accompanying consolidated balance sheets of Gerdau S.A. and subsidiaries (the Company) as of December 31, 2021, the related consolidated statements of income, comprehensive income, changes in equity, and cash flows for each of the years in the two year period ended December 31, 2021 and the related notes (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021, and the results of its operations and its cash flows for each of the years in the two year period ended December 31, 2021, in conformity with International Financial Reporting Standards, as issued by the International Accounting Standards Board.

We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.

#### NOTE 1 — GENERAL INFORMATION
Gerdau S.A. is a publicly traded corporation *(sociedade anônima)* with its corporate domicile in the city of São Paulo, Brazil. Gerdau S.A and subsidiaries (collectively referred to as the "Company") is a leading producer of long steel in the Americas and one of the largest suppliers of special steel in the world. In Brazil, the Company also produces flat steel and iron ore, activities which expanded the product mix and made its operations even more competitive. The Company believes it is the largest recycler in Latin America and around the world it transforms each year millions of tons of scrap into steel, reinforcing its commitment to sustainable development of the regions where it operates. Gerdau is listed on the São Paulo, New York and Madrid stock exchanges.

The Consolidated Financial Statements of Gerdau S.A and subsidiaries were approved by the Board of Directors on March 31, 2023.

#### NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING PRACTICES
2.1 — Basis of Presentation

The Company's Consolidated Financial Statements have been prepared in accordance with and are in compliance with 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 significant to the Consolidated Financial Statements are stated in Note 2.17. The Consolidated Financial Statements have been prepared using historical cost as its basis, except for the valuation of certain financial instruments, which are measured at fair value.

The Company adopted all applicable standards and revisions of standards and interpretations issued by the IASB or the IFRS Interpretations Committee that are effective as of December 31, 2022.

a) Investments in Subsidiaries

The Company's consolidated financial statements include the financial statements of Gerdau S.A. and all its subsidiaries. The Company controls an entity when it is exposed or has the right to variable returns arising from their involvement with the entity and has the ability to affect those returns due to the power exercised over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the Company. They are deconsolidated from the date that control ceases.

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 business combinations, 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 identified assets and liabilities acquired. Intercompany transactions and balances are eliminated in the consolidation process. Gains or losses resulting from transactions among consolidated entities of the Company are also eliminated.

b) Investments in Joint ventures and Associate companies

Joint ventures are those in which the control is held jointly by the Company and one or more partners. An associate company is one in which the Company exercises significant influence, but over which it does not have control. Investments in joint ventures and associate companies are recorded under the equity accounting method.

c) Equity in Earnings of Unconsolidated Companies

According to this method, investments are recognized in the consolidated balance sheet at acquisition cost and are adjusted subsequently based on the Company's share in the earnings and in other changes in the net assets of the Associates and Joint Ventures. The balances of the investments can also be reduced due to impairment losses. Furthermore, dividends received from these companies are recorded as reductions in the value of the investments.

[**Table of Contents**](#TOC)

2.2 —Foreign Currency Translation

a) Functional and Reporting Currency

The functional currency of an entity is the currency of the primary economic environment where it operates. The Consolidated Financial Statements are presented in Brazilian Reais (R$), which is the functional and reporting currency of the Company. The functional currencies of the subsidiaries located in other countries are the currencies of the respective countries, with the conversion to Reais being carried out as disclosed in items b) and c) below. All balances were rounded to the nearest thousand, unless otherwise stated.

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 functional currency of the Company and the reporting currency of its Consolidated Financial Statements, at the exchange rates at the dates of the transactions.

c) Translation of financial statements in foreign currency

The results of operations and financial position of all subsidiaries included in the consolidated financial statements, along with equity investments, which have functional currencies different from the Company's reporting currency are translated into the reporting currency as follows:

&nbsp;&nbsp;&nbsp;&nbsp;**i)** Asset and liability balances are translated at the exchange rate in effect at the balance sheet date;

**ii)** Income and expenses are translated using the average monthly exchange rates for the year;

**iii)** Translation gains and losses resulting from the above methodology are recognized in Equity, in the Statement of Comprehensive Income, in the account named "Other reserves - Cumulative translation adjustment"; and

**iv)** The amounts presented in the cash flow are extracted from the converted changes in assets, liabilities and results.

d) Hyperinflation in Argentina

Argentina is considered a country with hyperinflation and for this reason, the financial information of the subsidiaries located in this country are being updated so that their values are shown in the monetary unit of measurement at the end of the year, which considers the effects measured by the inflation rates in this country.

2.3 — Financial Assets

At initial recognition, a financial asset is classified as measured at amortized cost, at fair value through profit or loss or at fair value through other comprehensive income. Financial assets are not reclassified subsequent to initial recognition, unless the Company changes the business model for the management of financial assets. The Company performs an evaluation of the business model objective in which a financial asset is held in the portfolio because this better reflects the way in which the business is managed.

**a) Financial assets at amortized cost**

These assets are measured subsequently to initial recognition at the amortized cost using the effective interest method. The amortized cost is reduced by impairment losses. Interest income, foreign exchange gains and losses and impairment are recognized directly in income. Any gain or loss on derecognition is recognized on statement of income.

**b) Financial assets measured at fair value through profit or loss**

These assets are measured subsequently to initial recognition at the fair value. The net result, including interest, is recognized directly in income.

[**Table of Contents**](#TOC)

**c) Financial assets measured at fair value through other comprehensive income**

These assets are measured subsequently to initial recognition at fair value. Interest income calculated using the effective interest method, exchange gains and losses and impairment are recognized in the statement of income. Other net results are recognized in other comprehensive income. In derecognition, the accumulated result in other comprehensive income is reclassified to the statement of income.

**d) Impairment of financial assets**

The Company measures the impairment of financial assets in an amount equal to the Expected credit loss. In determining whether the credit risk of a financial asset has increased significantly since the initial recognition and in estimating the expected credit losses, the Company considers reasonable and supportable information that is significant and available without undue cost or effort. This includes quantitative and qualitative information and analysis, based on the Company's historical experience, credit assessment and considering forward-looking information. The impairment loss of financial assets was calculated based on the credit risk analysis, which includes the historical losses, the individual situation of the clients, the situation of the economic group to which they belong, the real guarantees for the debts and the evaluation of the legal advisors and is considered sufficient to cover possible losses on amounts receivable, in addition to a prospective assessment that takes into account the change or expectation of change in economic factors that affect expected credit losses, which will be determined based on probabilities weighted. The Company presents the impairment of the financial assets in the Statement of Income in the line of Impairment of financial assets.

**e) Derecognition**

The Company derecognizes a financial asset when expire the contractual rights of the cash flows of the asset, or when the Company transfers the contractual rights of that cash flows in a transaction in which substantially all the risks and benefits of the financial asset are transferred or in which the Company neither transfers nor maintains substantially all the risks and benefits of the financial asset and also does not retain control over the financial asset.

**f) Offset**

Financial assets and liabilities are offset and the net amount presented in the balance sheet when, and only when, the Company currently has a legally enforceable right to offset the amounts and intends to settle them on a net basis or to realize the asset and settle the liability simultaneously.

**g) Financial Instruments**

A financial asset is measured at amortized cost if it meets both of the following conditions and is not designated as measured at fair value through profit or loss: it is maintained within a business model whose objective is to maintain financial assets to receive contractual cash flows; and its contractual terms generate, at specific dates, cash flows that are related only to payment of principal and interest outstanding amounts.

A debt instrument is measured at fair value through other comprehensive income if it meets both of the following conditions and is not designated as measured at fair value through profit or loss: it is maintained within a business model whose objective is achieved both by receipt of contractual cash flows and sale of financial assets; and its contractual terms generate, on specific dates, cash flows that are only payments of principal and interest on the outstanding principal amount. In the initial recognition of an investment in an equity instrument that is not held for trading, the Company may irrevocably choose to present subsequent changes in the fair value of the investment in other comprehensive income. This choice is made investment by investment.

The Company performs an evaluation of the business model objective in which a financial asset is held in the portfolio because this better reflects the way in which the business is managed, and the information is provided to Management. The information considered includes: the policies and objectives stipulated for the portfolio and the practical operation of those policies. They include the question of whether Management's strategy focuses on obtaining contractual interest income, maintaining a certain interest rate profile, matching the duration of financial assets with the duration of related liabilities or expected outflows of cash, or the realization of cash flows through the sale of assets; how the performance of the portfolio is evaluated and reported to the Company's Management; the risks that affect the performance of the business model (and the financial asset held in that business model) and the manner in which those risks are managed; the frequency, volume and timing of sales of financial assets in prior periods, the reasons for such sales and their expectations about future sales.

[**Table of Contents**](#TOC)

**h) Evaluation on whether contractual cash flows are only payments of principal and interest**

For the purposes of this valuation, the 'principal' is defined as the fair value of the financial asset at the initial recognition. 'Interest' is defined as a consideration for the time value of money and for the credit risk associated with the principal amount outstanding over a given period of time and for the other underlying risks and costs of borrowing (e.g. liquidity risk and costs administrative costs), as well as a profit margin.

The Company considers the contractual terms of the instrument to assess whether contractual cash flows are only principal and interest payments. This includes assessing whether the financial asset contains a contractual term that could change the timing or value of the contractual cash flows so that it would not meet that condition. In making this assessment, the Company considers: contingent events that modify the value or the time of cash flows; terms that may adjust the contractual rate, including variable rates; the prepayment and the extension of the term; and terms that limit the Company's access to cash flows of specific assets (for example, based on the performance of an asset).

The prepayment is consistent with the principal and interest payments criterion if the prepayment amount represents, for the most part, unpaid principal and interest amounts on the outstanding principal amount - which may include additional compensation on the early termination of the contract.

2.4 — Inventories

Inventories are measured at the lower of historical cost of acquisition or production and net realizable value. The acquisition and production costs include transportation, storage and non-recoverable taxes.

Net realizable value is the estimated sale price in the ordinary course of business less the estimated costs of completion and directly related selling expenses. Information regarding the allowance for adjustments to net realizable value is presented in Note 6.

2.5 — Property, Plant and Equipment

Property, plant and equipment are stated at historical cost, monetarily adjusted when applicable, less depreciation, except for land, which is not depreciated. The Company recognizes monthly to the construction costs of qualified assets, which are assets that, necessarily, require a substantial period of time to be finished for its intended use, the borrowing costs as part of the acquisition cost of the property, plant and equipment under construction based on the following capitalization criteria: (a) the capitalization period begins when the property, plant and equipment item is under construction in process and the capitalization of borrowing costs ceases 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 for the acquisition of property, plant and equipment; (c) borrowing costs capitalized do not exceed the interest expenses during the capitalization period; 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.

Depreciation is calculated under the straight-line method at rates that take into consideration the estimated useful life of the asset, its level of utilization and the estimated residual value of the asset at the end of its useful life. The estimated residual value and useful life of the assets are reviewed and adjusted, if necessary, at each year-end.

Subsequent costs are added to the carrying amount 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 carrying amount of replaced items is written-off. Other repairs and maintenance are recognized directly in income when incurred.

Mining exploration rights are classified as Land and Buildings in the Property, plant and equipment account. Exploration expenditures are recognized as expenses until the technical feasibility and commercial viability of mining activity is established and thereafter subsequent costs are capitalized. Costs for the development of new iron ore reserves or to expand the capacity of operating mines are capitalized and amortized based on the amount of iron ore extracted. Stripping costs (costs associated with removal of waste and other residual materials) incurred during the development phase of a mine, before production phase, are registered as part of the depreciable cost of asset. Subsequently, these costs are depreciated over the useful life of the mine. Spending on waste removal, after the start of production of the mine, are treated as production costs. Depletion of mines is calculated based on units of production.

The net book value of property, plant and equipment items is immediately impaired to its recoverable amount when the residual balance exceeds the recoverable amount.

[**Table of Contents**](#TOC)

2.6 — Goodwill

Goodwill represents the excess of the acquisition cost over the fair value net of the assets acquired, liabilities assumed and identifiable contingent liabilities of a subsidiary, joint venture, or associate company, at the respective acquisition date.

Goodwill is recorded as an asset and recorded under "Goodwill" account. Goodwill is not amortized and is subject to impairment tests annually or whenever there are indications of potential impairment. Any impairment loss is recorded as an expense in the income statement and cannot be reversed. Goodwill is allocated to the operating segments, which represents the lowest level at which goodwill is monitored by management.

Goodwill that forms part of the carrying amount of an investment in an associate or a joint venture is not separately recognized. The entire carrying amount of the investment in associate or joint venture 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 it carrying amount.

When a subsidiary, joint venture or associate is sold, goodwill is included in the determination of gains and losses on disposal.

2.7 — Other Intangible Assets

Other intangible assets are stated at acquisition cost, less accumulated amortization and impairment losses, when applicable. Intangible assets consist mainly of assets which represent the capacity to generate economic benefits from companies acquired based on relationships with customers and suppliers, software and others. Software development expenditures are capitalized when all aspects of the standard are met, in particular, the technical feasibility of completing the asset so that it is available for use.

Intangible assets with definite useful lives are amortized taking into consideration their actual use or a method that reflects their consumption of economic benefits. The net book value of intangible assets is impaired immediately to its recoverable value when the residual balance exceeds the recoverable amount (Note 2.8).

Intangible assets acquired in a business combination are recorded at fair value, less accumulated amortization and impairment losses, when applicable. Intangible assets that have a defined useful life are amortized over their useful lives using an amortization method that reflects the period of economic benefit use of the intangible asset to record amortization through the period of use of that intangible and is recorded in the cost of sales account. The intangible relationship with customers and suppliers is amortized based on an accelerated method that considers the expected future economic benefit provided over time by these new acquired customers and suppliers.

The Company reviews the amortization period and amortization method for its intangible assets with definite useful lives at the end of each year.

2.8 — Provision for Impairment of Assets and Reversal of Impairment

At each balance sheet date, the Company performs an assessment to determine whether there is evidence that the carrying amount of long-lived assets might be 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 to selling 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 be impaired, 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 recognizes a reduction in the book value of the asset (Impairment). The reduction to the recoverable amount of the asset is recorded as an expense. Goodwill impairment, after recognized, is not allowed to be reversed, even if circumstances that resulted in the impairment changes. Other assets impairment may be reversed if circumstances that resulted in the impairment no longer exists, but in these circumstances the reversal of impairment is limited to the residual depreciated balance of the asset at the time of the reversal, determined as if the impairment had not been recorded.

The Company does not believe there is a reasonable likelihood that a material change in the estimates or assumptions used to calculate long-lived asset impairment losses may occur. 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.

2.9 — Financial Liabilities and Equity Instruments

a) Financial liabilities

Financial liabilities are classified as amortized cost or at fair value through profit or loss. A financial liability is classified as fair value through profit or loss if it is classified as held for trading, it is a derivative, or it is designated as such at initial recognition. Financial liabilities measured at fair value through profit or loss are measured at fair value and the net result, including interest, is recognized in the income statement. Other financial liabilities are subsequently measured at amortized cost using the effective interest method. Interest expense, exchange gains and losses are recognized in income.

b) Derecognition

The Company derecognizes a financial liability when its contractual obligation is withdrawn, canceled or expired. The Company also derecognizes a financial liability when the terms are modified and the cash flows of the modified liability are substantially different, in which case a new financial liability based on the modified terms is recognized at fair value. In the derecognition of a financial liability, the difference between the carrying amount extinguished and the consideration paid (including any non-cash assets transferred or liabilities assumed) is recognized in the income statement.

c) Derivative Instruments and hedging

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 quotations obtained from market participants, at fair value at the balance sheet date.

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 beginning of hedge coverage and on an ongoing basis, whether the derivatives used in hedge transactions are highly effective in offsetting changes in the fair value or cash flows of hedged items. When a cash flow hedge instrument is sold, terminated, expired or exercised, the hedge is discontinued prospectively, but the cumulative unrealized gain or loss is recognized in the comprehensive income statement. The cumulative gain and loss is transferred from the comprehensive income and recognized in the income statement when the hedged transaction is recognized in the statement of income. When no more than one transaction is expected to occur, the accumulated gain or loss is immediately transferred to the income statement. In cases of net investment hedges, the amount recorded in the statement of comprehensive income is written off and recognized in the statement of income when the disposal of the hedged investment occurs. In addition, changes in the fair value of financial instruments not characterized as hedges are recognized in the line of (Loss) Gains on financial instruments, net, in the statement of income.

**d) Equity instruments**

The equity component is initially recognized by the difference between the fair value of the compound financial instrument as a whole and the fair value of the liability component. Any directly attributable transaction costs are allocated to the liability and equity components in proportion to their initial carrying amounts.

2.10 — Current and Deferred Income and Social Contribution Taxes

Current income and social contribution tax expense is calculated in conformity with enacted tax rate in effect at the balance sheet date in the countries where the Company's subsidiaries, associates and joint venture 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 in accordance with the tax bases. The expense for income tax and social contribution taxes comprises current and deferred taxes. Current tax and deferred tax are recognized in income unless they are recognized for a business combination, or for items directly recognized in equity through other comprehensive income.

Current tax is the estimated tax payable or receivable on the taxable income or loss for the year, at the tax rates effective at the balance sheet date. Deferred income tax and social contribution are recognized in its total on the differences generated between assets and liabilities recognized for tax purposes and corresponding to amounts recognized in the Financial Statements. However, deferred income and social contribution taxes are not recognized arising from the initial recognition of assets and liabilities in a transaction other than a business combination and that do not affect the tax basis. Income and social contribution taxes are determined based on

[**Table of Contents**](#TOC)

tax rates (and laws) effective at the balance sheet date and applicable when the respective income and social contribution taxes is paid. 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 the temporary differences can be used, and tax losses can be compensated and are presented in the balance sheet on a net basis in assets or liabilities, based on the balance of each subsidiary.

Deferred tax assets recorded for tax loss carryforwards are supported by projections of taxable income based on technical feasibility studies submitted annually to the Board of Directors of the Company and its subsidiaries, when applicable. These studies consider historical profitability of the Company and its subsidiaries, expectations of continuous profitability and estimates of the recovery of deferred tax assets over future years. Other deferred tax assets arising from temporary differences, mainly tax provision, are recognized according to their estimate of realization. Deferred income tax and social contribution assets are reviewed at each reporting date and will be reduced to the extent that their realization is not more likely than not based on future taxable income.

The Company recognizes a provision for tax matters only if a past event gives rise to a present obligation. The Company determines whether a present obligation exists at the end of the year considering all available evidence, including, for example, the opinion of legal advisors. The Company also considers whether it is more likely than not that there will be an outflow of assets and whether a reliable estimate can be made.

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 21 and 27.

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 plan assets, when applicable, and the related costs are recognized over the employees' service period. Any employee benefit plan surpluses are also recognized up to the probable amount of reduction in future contributions by the Company.

Actuarial remeasurement 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 in Note 21.

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, return on plan assets, future increases in health care costs, and rate of future compensation increases. In addition, the Company and its actuary use 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. The disclosures of relevant assumptions and estimates related to this matter are described in Note 21.

2.12 — Other Current and Non-current Assets and Liabilities

Other current and non-current assets and liabilities 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 are adjusted by contractual financial charges plus foreign exchange variation, when applicable. These contracts have an expiration date, with the possibility of extension of time by agreement between the parties. Sales and purchases of raw materials and products are made under terms and conditions contractually established between the parties.

2.14 — Dividends and Interest on equity

The bylaws of Gerdau S.A. requires dividends of not less than 30% of the annual net income adjusted by 5% representing the constitution of legal reserve, and the constitution of tax incentives reserve; therefore, Gerdau S.A. records a liability 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

[**Table of Contents**](#TOC)

above. Brazilian Law 9,249/95 provides that a company may, at its sole discretion, consider dividends distributions to shareholders to be considered as interest on own capital, subject to specific limitations, which has the effect of a taxable deduction in the determination of income tax and social contribution. The limitation is the greater of (i) shareholders' equity multiplied by the TJLP (Long-Term Interest Rate) rate or (ii) 50% of the net income in the fiscal year. This expense is not recognized for the purpose of preparing the financial statements and therefore does not impact net income.

2.15 — Revenue Recognition

Net sales are presented net of taxes and discounts. The significant judgment made by the Company is presented in Note 2.17 and regarding revenue recognition it considers that revenue is derived from the single performance obligation to transfer its products under arrangements in which the transfer of control of the products and the fulfillment of the Company's performance obligation occur at the same time and that revenue from the sale of goods is recognized when the Company has transferred control of the goods to the buyer and the buyer obtains the benefits from the goods, the potential cash flows and the amount of revenue (the transaction price) can be measured reliably, and the consideration is to be transferred, which means it is probable that the Company will collect the consideration to which it is entitled to in exchange for the goods.

The significant judgment also considers whether the customer has obtained control over the asset depends on when the goods are made available to the carrier or the buyer takes possession of the goods, depending on the delivery terms. For the Company's operations, generally the criteria to recognize revenue has been met when its products are delivered to its customers (CIF term) or to a carrier who will transport the goods to its customers (FOB term) and these are the point in time when the Company has completed its performance obligations. Revenue is measured at the transaction price of the consideration received or receivable, the amount the Company expects to be entitled to.

The Company's products follow industry production standards for its applications. Historically, only a small portion of the Company's products are returned or have claims filed against the sale as result of quality complaints or other problems. Claims may be one of the following: product shipped and billed to an end customer that did not meet industry quality standards, such as physical defects in the goods, goods shipped to the wrong location or goods shipped outside acceptable time parameters. The Company estimates the consideration for such claims and reduces the amount of revenue recognized.

The warranties and claims arise when the product fails on the criteria mentioned above. Sales-related warranties associated with the goods cannot be purchased separately and they serve as an assurance that the products sold comply with agreed specifications. Accordingly, the Company accounts for warranties in accordance with IAS 37. Warranties and claims represent immaterial amounts to the Company.

2.16 — Investments in Environmental Protection and Environmental liabilities

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 recorded as expense. Liabilities are recorded when environmental assessments or remedial efforts are probable, and the cost can be reasonably estimated based on discussions with the environmental authorities and other assumptions significant 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 when the aggregate amount of the obligation and the amount and timing of cash disbursements are established or can be reliably estimated.

2.17 — Use of Judgements and Estimates

The preparation of the Consolidated Financial Statements requires estimates to record certain assets, liabilities and other transactions. To make these estimates, Management uses 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. As such, the Consolidated Financial Statements include estimates with respect to estimates referring mainly to revenue recognition (Note 2.15), the recoverable amount of goodwill and long-lived assets (Note 30), provisions for tax, civil and labor claims (Note 19), recoverability of deferred tax assets (Note 8), estimates in selecting interest rates, return on assets, mortality tables and expectations for salary increases (Note 21), and long-term incentive plans through the selection of the valuation model and rates (Note 27). Actual results could differ from those estimates.

2.18 — Business Combinations for the Financial Statements

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. Amounts related to the Company's interest in the acquired company before the acquisition date, and that were 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 for under the acquisition method. The cost of the acquisition is measured at the fair values (at the date of the transaction) of the assets transferred, liabilities incurred or assumed, and equity instruments issued by the Company in exchange for 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 shareholders' 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.

c) Increases/decreases in non-controlling interests

Subsequent increases/decreases in interest in subsidiaries, after the Company has obtained control, are treated as acquisitions/reductions of shares from non-controlling shareholders. The identifiable assets and liabilities of the acquired entity are not subject to a further revaluation and the positive or negative difference between the cost of such subsequent acquisitions/reductions and the net amount disbursed/received from the Company's proportional portion is recorded in 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.

2.19 — Segment Information

The bodies responsible for making operational decisions, allocating resources and evaluating performance include the Board of Executive Officers and the Board of Directors, collectively, the "senior management". The information presented to the senior management with the respective performance of each segment is derived from the records kept in accordance with IFRS, with some reallocations between the segments.

The Company's segments are as follows: Brazil Operations (includes operations of steel and iron ore in Brazil, except Special Steel), North America Operations (includes all operations in North America, including the joint venture in Mexico, with the exception of Special Steel), South America Operations (includes all operations in South America, except Brazil and includes the Joint venture in Dominican Republic and Colombia) and Special Steel Operations (including special steel operations in Brazil and in the United States and the joint venture in Brazil).

2.20 — Earnings per Share

The tables presented in Note 25 reconcile net income to the amounts used to calculate basic and diluted earnings per share. The Company has no instruments considered antidilutive that should be excluded from the calculation of diluted EPS.

The calculation of basic EPS has been based on the profit attributable to shareholders and weighted-average number of shares outstanding. The calculation of diluted EPS has been based on the profit attributable to shareholders and weighted-average number of shares outstanding after adjustment for the effects of all dilutive potential shares.

[**Table of Contents**](#TOC)

2.21 — Long-term incentive plans

The Company settles its Long-term incentive plans by delivering its own shares, which are held in treasury until the exercise of the options by the employees. Additionally, the Company granted the following long-term incentive plans: Restricted Shares and Performance Shares, as presented in Note 27.

**2.22 — Leasing Operations**

The Company, as a lessee, recognizes a right-of-use asset that represents its right to use the leased asset and a lease liability that represents its obligation to make lease payments. Exemptions are available for short-term leases and low-value items. The Company recognizes new assets and liabilities for its operating leases. The Company recognizes a depreciation of rights of use assets and financial expense on lease obligations. Variable elements of payments related to leases (such as, for example, a lease for machinery and/or equipment with parts of payments based on the productivity of the asset) are not considered in the calculation of the liability, being recorded as operating expense. The discount rates used by the Company were obtained in accordance with market conditions.

**2.23 — Tax Claims**

The Company and its subsidiaries are party in judicial and administrative proceedings involving tax matters, as disclosed in Note 19. In note 2.17, the Company discloses that provisions for tax liabilities require the use of judgments and estimates.

The Company discloses different taxes related to indirect taxes (ICMS, IPI, PIS and COFINS) and they fall into the scope of IAS 37, which establishes that a liability is a present obligation of the entity arising from past events and the settlement of which is expected to result in an outflow from the entity of resources embodying economic benefits. In these tax discussions, past events give rise to present obligations, which based on all available evidence, resulted in a more likely than not present obligation. Contingent liabilities are not recognized, since the possibility of an outflow of resources embodying economic benefits is not more likely than not. Since contingent liabilities may develop in a way not initially expected, they are assessed continually to determine whether an outflow of resources embodying economic benefits has become probable. If it becomes probable that an outflow of future economic benefits will be required for an item previously dealt with as a contingent liability, a provision is recognized in the financial statements of the period in which the change in probability occurs.

Contingent liabilities disclosures related to income taxes (IRPJ and CSLL) also fall into the scope of IAS 37, while tax provisions related to income taxes fall into the scope of IAS 12. Management considers the guidance in IFRIC 23, with the assistance of its legal advisors, to record tax provisions in accordance with applicable laws and appropriately considers uncertainties over income taxes for purposes of recognition and measurement. The assessment provided by the Company in these cases considers whether it is probable that a taxation authority will accept an uncertain tax treatment and a provision is recognized when the uncertain income tax treatment is no longer probable that it will be accepted by the taxation authority. During every fiscal year, the Company reassess its judgment and estimates to check if the facts and circumstances on which the judgment or estimate was based changed as a result of new information that affects the judgment or estimate.

**2.24 — Trade accounts payable (domestic market, debtor risk and imports)**

Trade accounts payable balances are obligations payable for the acquisition of goods or services in the normal course of business, being classified as current liabilities due to maturity of up to one year in the Balance Sheet and in the Cash Flow variations are presented as an increase or decrease in trade accounts payable. These amounts are initially recognized at fair value and subsequently measured at amortized cost.

In import operations of coal and other raw materials abroad, the supplier may request the issuance of a letter of credit or similar risk mitigation instrument to ship the products, being the costs associated with issuing the letter of credit recognized as a financial expense.

The breakdown of trade accounts payable balances is presented in Note 14.

**2.25 — New IFRS and Interpretations of the IFRIC (International Financial Reporting Interpretations Committee)**

The issued and/or reviewed IFRS standards made by the IASB that are effective for the year started in 2022 had no impact on the Company's Financial Statements. In addition, the IASB issued/reviewed some IFRS standards, which have mandatory adoption for the year 2023 and/or after, and the Company does not expect material impacts on its Financial Statements.

[**Table of Contents**](#TOC)

-Issuance of IFRS 17 – Insurance contracts. This standard replaces standard IFRS 4 – Insurance contracts and defines the principles for recognition, measurement, presentation and disclosure of insurance contracts. This standard is effective for fiscal years beginning on/or after January 1, 2023. The Company will not have an impact on its Financial Statements with the effective of this standard, as it does not issue insurance contracts.

- Amendment to IAS 1 - Classification of liabilities as Current or Non-current. It clarifies aspects to be considered for the classification of liabilities as Current Liabilities or Non-current Liabilities. This amendment to the standard is effective for fiscal years beginning on/or after January 1, 2023. The Company does not expect material impacts on its Financial Statements.

- Amendment to IAS 1 and Disclosure of Accounting Policies. It clarifies aspects to be considered in the disclosure of accounting policies. This amendment to the standard is effective for fiscal years beginning on/or after January 1, 2023. The Company does not expect material impacts on its Financial Statements.

- Amendment to IAS 8 – Definition of Accounting Estimates. It clarifies aspects to be considered in the definition of accounting estimates. This amendment to the standard is effective for fiscal years beginning on/or after January 1, 2023. The Company does not expect material impacts on its Financial Statements.

- Amendment to IAS 12 – Deferred Tax related to Assets and Liabilities arising from a Single Transaction. It clarifies aspects to be considered when recognizing deferred tax assets and liabilities related to taxable temporary differences and deductible temporary differences. This amendment to the standard is effective for fiscal years beginning on/or after January 1, 2023. The Company does not expect material impacts on its Financial Statements.

- Amendment to IFRS 16 – Lease Liability in a Sale and Leaseback. It clarifies aspects to be considered in the accounting treatment of an asset transfer in a sale. This amendment to the standard is effective for fiscal years beginning on/or after January 1, 2024. The Company does not expect material impacts on its Financial Statements.

- Amendment to IAS 1 – Non-current Liabilities with Covenants. It clarifies aspects of separate classifications in the balance sheet of current and non-current assets and liabilities, establishing the presentation based on liquidity when it provides information that is reliable and more relevant. This amendment to the standard is effective for fiscal years beginning on/or after January 1, 2024. The Company does not expect material impacts on its Financial Statements.

**2.26 - Risk of disease outbreaks and health pandemic: COVID-19**

The risks arising from disease outbreaks, epidemics and pandemics, notably those arising from the COVID-19 pandemic, can significantly contribute to the deterioration of economic conditions and could, among other consequences, (i) negatively impact global demand for steel or lower market prices for products, which could result in a continued reduction in the Company's sales, operating income and cash flows; (ii) make it more difficult or costly to obtain finance for operations or refinance debt in the future; (iii) harm the financial condition of some of our customers and suppliers; and (iv) reduce investment programs. The Company believes that it has no evidence of any going concern risk. However, changes that deteriorate the economic and business environment, or relevant changes in the economy or financial market that lead to an increase in risk perception or reduction of liquidity and refinancing capacity, if manifested in a greater intensity than that anticipated in the scenarios contemplated by Management, may lead the Company to review its projections and, eventually, may affect the Company's ability to meet its obligations and/or lead to the recognition of losses due to the non-recoverability of its assets. The Company maintains constant monitoring of commodity price, interest rate and exchange rate risks, credit risk management and capital management (Note 17.c).

**2.27 - Risks of international conflicts**

The Russian invasion of Ukraine could have a material adverse effect on the overall macroeconomic environment, which might include demand for steel and iron ore and prices, as well as increasing energy costs. Both the conflict itself and the sanctions imposed (and further sanctions that may be imposed), as well as potential Russian responses to sanctions, have had and could have further destabilizing effects on financial markets and certain commodity markets. The conflict could escalate militarily both regionally and globally; any substantial escalation would have a material adverse effect on macroeconomic conditions. In addition, sanctions may remain in place beyond the duration of any military conflict and have a long-lasting impact on the region and globally and could adversely impact the Company's results of operations and financial condition.

&nbsp;&nbsp;&nbsp;&nbsp;(1) Company jointly controlled by Gerdau Next S.A. with Randon Serviços e Participações Ltda. for exploring the activity of providing leasing services for heavy or agricultural machinery and equipment, railway modules and containers, as well as heavy and light commercial vehicles, intended for road and rail transport.

&nbsp;&nbsp;&nbsp;&nbsp;(2) Company jointly controlled by Gerdau Next S.A. with Spacetime Labs – STA do Brasil Sistemas de Informação S.A. for activity focused on the development of artificial intelligence and robotic systems for basic industries.

Although the Company owns more than 50% of Gerdau Corsa S.A.P.I. de C.V. and Gerdau Summit Aços Fundidos e Forjados S.A., it does not consolidate the financial statements of these joint venture entities, due to joint control agreements with the other shareholders that prevent the Company from controlling the decisions in conducting the joint venture's business.

On November 30, 2021, the Company, together with Grupo Córdova (comprised of Corcre, S.A.P.I. de C.V. and Juan Angel Córdova Creel), concluded the stages of the corporate reorganization of operations in Mexico involving its subsidiary Sidertúl, S.A. de C.V. (Sidertúl) and the joint venture Gerdau Corsa, S.A.P.I. de C.V. (Gerdau Corsa) and its subsidiary Aceros Corsa, S.A. de C.V. (Aceros Corsa). The corporate reorganization was approved by the shareholders of the companies involved, as well as by the Comisión Federal de Competencia Económica – COFECE and took effect as of December 1, 2021. The corporate reorganization of the companies Sidertúl and Aceros Corsa by Gerdau Corsa is part of the process of reorganization and simplification of the corporate structure in Mexico, with the objective of: (i) strengthening the financial structure of Gerdau Corsa, with the reduction of leverage and financial expenses; (ii) centralizing the main business activities, generating greater operational efficiency for the companies involved; and (iii) optimizing internal processes, creating synergy in activities and economies of scale by reducing administrative, operational and tax costs. Additionally, the corporate reorganization reinforces the Company's commitment to its operations in Mexico. As a result of the corporate reorganization, the Company increased its interest in Gerdau Corsa from 70% to 75%, maintaining joint control of this company with Grupo Córdova.

As a result of this corporate reorganization of operations in Mexico, the Company recognized a gain in 2021 of R$193,651, which is calculated as the difference between the carrying amount and the fair value of Sidertúl and R$193,334 for the recycling to income of the cumulative translation adjustments, which is required as the Company lost Sidertúl control, as presented in the statement of comprehensive income. The corporate reorganization resulted in the loss of control of Sidertúl and as required by IFRS, the Company carried out a proportional write-off of goodwill from the North America segment in the amount of R$549,898, as described in Note 11, measured on the basis of the relative values of the operation disposed of and the portion of the cash-generating unit retained.

**3.5 — Acquisition of subsidiary**

On November 30, 2020, the Company, through its subsidiary Gerdau Aços Longos SA, concluded, after complying with the respective precedent conditions, including the approval of the Administrative Council for Economic Defense - CADE, the acquisition of 96.35% of the total and voting shares issued by Siderúrgica Latino-Americana S.A.

The foreign subsidiaries of the Company are subject to taxation at rates ranging between 23% and 35%, without considering there are subsidiaries abroad with zero tax rate, which have mainly financial activities.

Under "Trade Accounts Payable - Domestic Market", the Company presents balances payable arising from the acquisition of goods and services in the domestic markets of each of the countries where the Company and its subsidiaries operate.

The Company has contracts with financial institutions in order to allow its suppliers to anticipate their receivables through an operation called "Trade Accounts Payable – Debtor Risk". In this operation, suppliers can transfer, at their discretion, the right to receive the securities to a financial institution, which, in turn, becomes the holder of the rights of the suppliers' receivables. The average discount rate on risk transactions carried out by our suppliers with financial institutions in Brazil and with subsidiaries in the United States was based on market conditions. The transfer of the right to receive the Company's securities, at the supplier's discretion, does not change the payment term, nor does it imply the payment of interest by the Company, as the financial cost of such transfer is the responsibility of the supplier.

The balances presented as "Trade Accounts Payable - Imports" substantially refer to the purchase of coal and other raw materials abroad, where in commercial transactions the supplier may require the issuance of a letter of credit or similar risk mitigation instrument to ship the products. On December 31, 2022, contracts negotiated via letter of credit had a payment term of up to 180 days and rates that also varied, depending on market conditions.

The Company permanently monitors the composition of the portfolio and the conditions established with suppliers, which have not undergone significant changes in relation to what had been practiced historically.

The fair values of Loans and Financing and Debentures are based on market premises, which may take into consideration discounted cash flows using equivalent market rates and credit rating. All other financial instruments, which are recognized in the Consolidated Financial Statements at their carrying amount, are substantially similar to those that would be obtained if they were traded in the market. However, because there is no active market for these instruments, differences could exist if they were settled in advance. The fair value hierarchy of the financial instruments above are presented in Note 17.g.

c) Risk factors that could affect the Company's and its subsidiaries' businesses:

**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 operates in a commodity market, net sales 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. Furthermore, the Company may contract derivatives in order to reduce this risk.

**Interest rate risk:** this risk arises from the effects of fluctuations in interest rates applied to the Company's financial liabilities or assets and future cash flows and income. The Company evaluates its exposure to these risks: (i) comparing financial assets and liabilities denominated at fixed and floating interest rates and (ii) monitoring the variations of interest rates like SOFR and CDI. Accordingly, the Company may enter into interest rate swaps in order to reduce this risk.

**Exchange rate risk:** this risk is related to the possibility of fluctuations in exchange rates affecting the amounts of financial assets or liabilities or of future cash flows and income. The Company assesses its exposure to the exchange rate by measuring the difference between the amount of its assets and liabilities in foreign currency. The Company understands that the accounts receivables originated from exports, its cash and cash equivalents denominated in foreign currencies and its investments abroad are more than equivalent to its liabilities denominated in foreign currency. Since the management of these exposures occurs at each operation level, if there is a mismatch between assets and liabilities denominated in foreign currency, the Company may contract derivative financial instruments in order to mitigate the effect of exchange rate fluctuations.

**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 adopt the procedure of analyzing in details of the financial position of their customers, establishing a credit limit and constantly monitoring their balances. Regarding financial

[**Table of Contents**](#TOC)

investments, the Company only carries out transactions with first-rate institutions and with low credit risk, as assessed by rating agencies and risk mitigation parameters defined in the Company's internal guidelines.

**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) based on internal policies and benchmarks. The Key Performance Indicators (KPI) related to the "Capital Structure Management" objective are: WACC (Weighted Average Cost of Capital), Net Debt/EBITDA (Earnings before interest, income tax, depreciation and amortization), Coverage Ratio of Net Financial Expenses (EBITDA/Net Financial Expenses) and Debt/Total Capitalization Ratio. Net Debt is formed by the principal of the debt reduced by cash, cash equivalents and short-term investments (notes 4, 15 and 16). Total Capitalization is formed by the Total Debt (composed of the principal of the debt) and the Equity (Note 24). The Company may change its capital structure, according to economic and financial conditions, in order to optimize its financial leverage and debt management. At the same time, the Company seeks to improve its ROCE (Return on Capital Employed) through the implementation of working capital management and an efficient program of investments in property, plant and equipment. In the long term, the Company seeks to remain within the parameters below, admitting occasional variations in the short term:

---

| | |
|:---|:---|
| Net debt/EBITDA | Less or equal to 1.5 times |
| Gross debt limit | R$12 billion |
| Average maturity | more than 6 years |

---

These key indicators are used to monitor objectives described above and may not necessarily 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 and financing, and debentures are presented in Notes 15 and 16, respectively.

#### Sensitivity analysis:
The Company performed a sensitivity analysis, which can be summarized as follows:

#### Impacts on Statements of Income

---

| | | | |
|:---|:---|:---|:---|
| **Assumptions** | **Percentage of change** | **2022** | **2021** |
| Foreign currency sensitivity analysis | 5% | 113778 | 19036 |
| Interest rate sensitivity analysis | 10 bps | 32377 | 55964 |
| Sensitivity analysis of changes in prices of products sold | 1% | 824122 | 783451 |
| Sensitivity analysis of changes in raw material and commodity prices | 1% | 486066 | 437210 |
| Currency forward contracts | 5% | 9507 |  |
| Commodity contracts | 5% | 2899 | 4892 |

---

**Foreign currency sensitivity analysis:** As of December 31, 2022, the Company is mainly exposed to variations between the Real and the Dollar. The sensitivity analysis carried out by the Company considers the effects of a 5% increase or decrease between the Real and the Dollar in its non-hedged debts, trade accounts receivable - exports from Brazil and trade accounts payable - imports (also including the variation between the Argentinian Peso and the Dollar). In this analysis, if the Real/Argentinian Peso appreciates against the Dollar, this would represent a gain of R$113,778 (R$19,036 as of December 31, 2021). If the Real/Argentinian Peso depreciates against the Dollar, this would represent an expense of the same amount.

The net values of other assets and other liabilities in foreign currencies do not present significant risks of impacts due to fluctuations in the exchange rate.

**Interest rate sensitivity analysis:** The interest rate sensitivity analysis made by the Company considers the effects of an increase or reduction of 10 basis point (bps) on the average interest rate applicable to the floating part of its debt. The calculated impact, considering this variation in the interest rate totals R$32,377 as of December 31, 2022 (R$55,964 as of December 31, 2021) and would impact the Financial expenses account in the Consolidated Statements of Income. The specific interest rates to which the Company is exposed are related to the loans, financing, and debentures presented in Notes 15 and 16, and are mainly comprised by SOFR and CDI — Interbank Deposit Certificate.

**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 sale price of the Company's products and the price of raw materials and other inputs used in the production process, mainly for operating in a commodity 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, considering the revenues and costs for the year ended on December 31, 2022, totals R$824,122 (R$783,451 as of December 31, 2021) and the variation in the price of raw materials and other inputs totals R$486,066 as of December 31, 2022 (R$437,210 as of December 31, 2021). The impact in 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 currency forward contracts:** the Company has exposure to dollar forward contracts for some of its assets and liabilities. The sensitivity analysis carried out by the Company considers the effects of a 5% increase or decrease in the Dollar against the Brazilian Real/Argentinian Peso, and its effects on the mark to market of these derivatives. A 5% increase in the Dollar against the Real/Argentinian Peso represents an income of R$9,507 (R$0 as of December 31, 2021) and a 5% decrease in the Dollar against the Real/Argentinian Peso represents an expense of the same amount. Forward contracts in Dollar/Real/Argentinian Peso were intended to cover asset and liability positions in Dollars and the effects of the mark to market of these contracts were recorded in the Consolidated Statement of Income. Dollar forward contracts to which the Company is exposed are presented in note 17.e.

**Sensitivity analysis of commodity forward contracts:** the Company has exposure to Commodity forward contracts (coal, natural gas and nickel) for some of its liabilities. The sensitivity analysis carried out by the Company considers the effects of a 5% increase or decrease in the price of the commodity, and its effects on the mark to market of these derivatives. A 5% increase in the price of the commodity represents an income of R$2,899 (R$4,892 as of December 31, 2021), and a 5% decrease in the price of the commodity represents an expense of the same amount. Coal forward contracts were intended to cover liability positions and the mark to market effects of these contracts were recorded in the Consolidated Statement of Income. Commodity forward contracts to which the Company is exposed are presented in Note 17.e.

e) Operations with derivative financial instruments

**Risk management objectives and strategies:** In order to execute its strategy of sustainable growth, the Company implements risk management strategies in order to mitigate market risks.

The objective of derivative transactions is always related to mitigating market risks as stated in our policies and guidelines. The monitoring of the effects of these transactions is performed monthly by the Financial Risk Management Committee, which validates the mark to market of these transactions. All derivative financial instruments are recognized at fair value in the Consolidated Financial Statements of the Company.

[**Table of Contents**](#TOC)

**Policy for use of derivatives:** The Company is exposed to various market risks, including changes in exchange rates, commodities prices and interest rates. The Company uses derivatives and other financial instruments to reduce the impact of such risks on the fair value of its assets and liabilities or in future cash flows and income. The Company has established policies to evaluate the market risks and to approve the use of derivative transactions related to these risks. The Company enters into derivative financial instruments solely to manage the market risks mentioned above and never for speculative purposes. Derivative financial instruments are used only when they have a related position (asset or liability exposure) resulting from business operations, investments and financing.

**Policy for determining fair value:** the fair value of derivative financial instruments is determined using models and other valuation techniques, including future prices and market curves.

Derivative transactions may include: interest rate and/or currency swaps, currency futures contracts and currency options contracts.

**Currency forward contracts:** The Company contracted forward contract operations, through which it receives a fixed dollar amount and pays a fixed Argentinian peso amount, both in local currency. Counterparties are always top-tier financial institutions with low credit risk.

The derivatives instruments can be summarized and categorized as follows:

f) Net investment hedge

The Company designated as hedge of part of its net investments in subsidiaries abroad the operations of Ten/Thirty Years Bonds. As a consequence, the effect of exchange rate changes on these debts on the amount of US$1.1 billion (designated as a hedge) has been recognized in the Statement of Comprehensive Income.

The Company demonstrated effectiveness of the hedge as of its designation dates and demonstrated the high effectiveness of the hedge from the contracting of each debt for the acquisition of these companies abroad, whose effects were measured and recognized directly in the Statement of Comprehensive Income as an unrealized gain, net of taxes, in the amount R$488.146 for the year ended on December 31, 2022 (loss of R$695,102 for the year ended on December 31, 2021).

[**Table of Contents**](#TOC)

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 abroad mentioned above against positive and negative changes in the exchange rate. This objective is consistent with the Company's risk management strategy. Prospective and retrospective tests demonstrated the effectiveness of these instruments.

g) Measurement of fair value:

IFRS 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. The standard also establishes a three-level hierarchy 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 (unadjusted) in active markets for identical assets and liabilities.

Level 2 - Inputs other than quoted prices included in Level 1 available, where (unadjusted) 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, 2022, 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 on a recurring basis and subject to disclosure requirements of IFRS 7 as of December 31, 2022 and December 31, 2021, are as follows:

The Company's tax advisors confirm that the procedures adopted by the Company regarding the tax treatment of profits earned abroad and the goodwill amortization, which led to the aforementioned lawsuits, have complied with the strict legality and, therefore, these lawsuits are classified as possible loss (but not likely).

Brazilian federal authorities and the judiciary branch are investigating certain issues relating to Administrative Board of Tax Appeals (CARF) proceedings, as well as specific political contributions made by the Company, with the purpose of determining whether the Company engaged in any illegal conduct. The Company previously disclosed that, in addition to its interactions with Brazilian authorities, the Company was providing information requested by the U.S. Securities and Exchange Commission ("SEC"). The Company has since been informed by the SEC's staff that it has closed its inquiry and therefore is not seeking any further information from the Company regarding these matters. The Company believes it is not possible at this time to predict the term or outcome of the proceedings in Brazil, and that there currently is not enough information to determine whether a provision for losses is required or any additional disclosures. Neither the Company, its controlling shareholders, board members and executive officers are part of any ongoing criminal publicly disclosed investigations, procedures or legal actions associated to the investigations made by the Brazilian federal authorities and judiciary branch related to CARF proceedings and political contributions made by the Company.

**Subsequent Event**

In compliance with Circular Letter No. 1/2023/CVM/SNC/SEP of February 13, 2023, the Company carried out a survey of its processes. The Company believes that, based on the opinion of its legal advisors, at this time, no cases were identified that could represent impacts on its financial statements arising from the decision of the STF on res judicata in tax matters that occurred on 02/08/2023.

b) Civil contingencies

**b.1)** A lawsuit arising from the request by 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 – Secretaria de Direito Econômico), the final opinion was that a cartel exists. The lawsuit was therefore forwarded to the Administrative Council for Economic Defense (CADE) for judgment, which resulted in a fine to the Company and other long steel producers, on September 23, 2005, an amount equivalent to 7% of gross revenues in the year before the Administrative Proceeding was commenced, excluding taxes (fine of R$245,070, updated by the judicial accountant on August 1, 2013 to R$417,820).

Two lawsuits challenge the investigation conducted by the Competition Defense System and its merits judgment, whose grounds are procedural irregularities, especially the production of evidence, based on an economic study, to prove the inexistence of a cartel. The Court, upon offer of bank guarantee letter, granted the suspension of the effects of CADE's decision. Both actions were dismissed, and their respective appeals were also rejected by the Federal Regional Court of the 1<sup>st</sup> Region.

Against both decisions, appeals were lodged with the Superior Court of Justice and the Federal Supreme Court, after admissibility judgment, the appeal to the Superior Court of Justice was admitted and well as substitution of the guarantee offered by insurance guarantee in a decision of October 8, 2019.

In the same order in which the Vice president Judge gave suspensive effect to the Special Appeal, in order to change the guarantee, the Extraordinary Appeal was dismissed, on the grounds of violation of res judicata with recognized general repercussion. Against this decision, the Company filed an Internal Appeal for the TRF1 Plenary, which was dismissed.

In a unanimous vote, the STJ annulled the fine and recognized that there was no due process of law, as CADE would have concluded without the necessary study of the market and the facts (Cf. STJ, REsp n.º 1.979.138 - DF (2021/0405949-3), Judge Benedito Gonçalves).

The STJ's decision is subject to appeal by the Brazilian government and Gerdau will continue to seek all appropriate legal remedies to defend its rights.

The Company denies having been engaged in any type of anti-competitive conduct and it is certain that it has not practiced the conduct attributed to it, understanding shared by its legal consultants.

**b.2)** The Company and its subsidiaries are parties to other demands of a civil nature that collectively have a discussion amount of approximately R$552,515. For these demands, no accounting provision was recorded, since they were considered as possible losses, based on the opinion of its legal counsel.

**c) Labor Contingencies**

The Company and its subsidiaries are parties to other labor claims that together have an amount of approximately R$820,032. For these claims, no accounting provision was made, since these were considered as possible losses, based on the opinion of its legal counsel.

#### III) Judicial deposits
The Company has judicial deposits related to tax, labor and civil lawsuits as listed below:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  |  | **2022** |  | **2021** |
| Tax |  | 1,603,136 |  | 1,449,699 |
| Labor |  | 67,911 |  | 73,709 |
| Civil |  | 154,852 |  | 135,971 |
|  |  | 1,825,899 |  | 1,659,379 |

---

The balance of tax judicial deposits as of December 31, 2022 includes the amount of R$1,504,984, which corresponds to judicial deposits made up to June 2017, referring to the same discussion on the inclusion of the ICMS in the tax base of PIS and COFINS and awaits termination of the lawsuits before the Brazilian courts in order to be returned to the Company.

The Company and its subsidiaries made judicial deposits and accounting provisions, which in turn were updated in accordance with the SELIC rate, which were referred to the unpaid amounts of PIS and COFINS since 2009, because the collection of which was fully suspended, due to the mentioned judicial deposits.

On March 15, 2017, the Brazilian Federal Supreme Court (STF — Supremo Tribunal Federal) ruled on a claim related to this matter, and by 6 votes to 4, concluded: "The ICMS does not comprise the tax base for PIS and COFINS assessment purposes". The STF decision, in principle, affects all the nine judicial proceedings, due to its general repercussion. Eight of these lawsuits already have a final favorable decision, and the gain was recognized when the decision was final and unappealable, considering for the purposes of calculation the exclusion of the ICMS informed in the invoices, as recognized in the final and unappealable decisions, and is preparing the documents to carry out the qualification of its credit and be able to start the compensation procedures and/or have already qualified before the Federal Revenue Service of Brazil. It is important to note that the Company still has a lawsuit for repetition of undue payments, which is awaiting the respective final and unappealable decision. In this lawsuit the Company seeks the recognition of R$683 million (R$643 million, net of related expenses) referring to credits prior to the filing of the lawsuit.

On May 13, 2021, the Federal Supreme Court ruled the Embargoes for Declaration that the National Treasury Attorney's Office had opposed, alleging that the Supreme Court's decision was silent on certain points, and requesting the modulation of the effects of the decision. In that judgment, the STF accepted, in part, the Embargoes for Declaration, to modulate the effects of the judgment whose production took place after March 15, 2017 (date on which RE No. 574.706 was judged), except for lawsuits or administrative proceedings filed up to that date, and rejected the embargoes regarding the allegation of omission, obscurity or contradiction and, in the point related to the ICMS excluded from the calculation basis of the PIS-COFINS contributions, it signed the understanding that it is the ICMS informed in the invoice.

[**Table of Contents**](#TOC)

After this judgment, the concept of virtually certain for the purposes of the entry of economic benefits and recognition of the asset and the corresponding gain started to be demonstrated. Thus, even though there was no final and unappealable decision on two lawsuits that were pending of judgment, the Company recognized in 2021, with sufficient reliability, the amounts of tax credits to which it is entitled, referring to credits prior to the filing of the lawsuits.

The amounts recognized in the Company's results related to the recovery of credits arising from the ICMS in the tax base of PIS and COFINS lawsuits (net of related expenses) was R$1.2 billion in 2021, of which, R$393,3 million in the Other Operating Income line and R$788.7 million in the Tax Credits Monetary Update line

Due to the economic moment strongly impacted by the pandemic caused by COVID-19, as well as the fact that the procedural legislation expressly provides the equivalence of cash and guarantee insurance, the subsidiary Gerdau Aços Longos S.A. requested the replacement of the amounts deposited by it over the years regarding the Inclusion of ICMS in the tax base of PIS and COFINS for a guarantee insurance presented by the Company, in the amount of R$1.7 billion, which complies with all the requirements established by the PGFN (Attorney General of the National Treasury) and can be converted into income at any time, ensuring that the Public Treasury receives all the amounts that may eventually be due at the end of the process.

In the lower court decision, therefore, there was a decision to release the funds deposited by the Company. The Public Treasury appealed to the Court and obtained a decision reversing the release of the amounts. The Company, then, filed a complaint to settle divergence between the decision handed down by Federal Judge, member of the 4<sup>th</sup> Specialized Panel of the Federal Regional Court of the 2<sup>nd</sup> Region, in the case files of process nº 50003743-37.2020.4.02.0000, and the jurisprudence of the Supreme Court (Theme nº 69). With an initially favorable injunction, the decision was later suspended to await the statement by the National Treasury regarding the fine for bad faith litigation applied to the Company. After the manifestation, which did not bring any additional element in relation to the fine for bad faith litigation applied, the Minister understood that the Complaint was not applicable due to the lack of exhaustion of ordinary channels.

The fine for bad faith litigation, applied due to the allegation of alleged attempt to mislead the Judiciary, was canceled by the Federal Regional Court of the 2<sup>nd</sup> Region, when it partially granted, unanimously, the interlocutory appeal filed by the Company. In December 2022, after judgment of the Declaration Embargoes opposed by the National Treasury, which upheld the favorable decision for the Company and the fine was definitively terminated.

**IV) Eletrobras Compulsory Loan — Centrais Elétricas Brasileiras S.A. (Eletrobras)**

The Compulsory Loan, instituted by the Brazilian government in order to expand and improve the energy sector of the country was charged and collected from industrial consumers with monthly consumption equal or greater than to 2000kwh through the "electricity bills" issued by the electric power distribution companies, was converted into credits to the taxpayers based on the annual value of these contributions made between 1977 and 1993. The legislation sets a maximum 20 years period to return the compulsory loan to the taxpayers, providing Eletrobras the possibility of anticipating this return through the conversion of those loans in shares of its own issuance.

Prior to the conversion of the credits into shares, those credits were monetary corrected through an indexer and quantifier, called Standard Unit (SU). However, the compulsory loan was charged to the companies in their monthly electricity bills, consolidated during the year, and only indexed by the SU in January of the following year, resulting in a lack of monthly monetary correction during the years of collection, as well as interest. This procedure imputed to taxpayers' considerable financial losses, particularly during the periods when the monthly inflation rates stood at high levels. In order to claim the appropriate interest and monetary correction subtracted by the methodology applied by Eletrobras, the Company (understood to be legally entities existing at the time and that later became part of Gerdau S.A.) filed lawsuits claiming credits resulting from differences on the monetary correction of principal, interest, default interest and other accessory amounts owed by Eletrobras due to the compulsory loans.

The Company maintain lawsuits pending before the Judiciary, dealing with the subject, with final and unappealable decisions on the merits, favorable to the Company. Regarding one of these processes, involving Gerdau S.A. and its subsidiary Seiva SA – Florestas e Indústrias, on November 25, 2020 a decision was issued that ratified the expert report prepared by the court expert appointed by the Court, establishing the amount to be received in favor of the companies. This decision was maintained by the Court of Justice of the State of Rio de Janeiro in judgment on August 10, 2021, and on September 10, 2021 Eletrobras made the judicial deposit/payment of the amount of the sentence determined by the Judiciary Branch of the State of Rio January, duly increased by interests and loss charges. Thus, considering the current procedural stage, the Company concludes that said asset, until then treated as contingent, due to uncertainties as to the term, form and amount that would be effectively paid and currently defined, fulfilled the accounting characteristics related to the entry of economic benefits, pursuant to paragraph 35 of IAS 37, which implied the recognition by the

[**Table of Contents**](#TOC)

Company, in the 3<sup>rd</sup> quarter of 2021, of gain in the statement of income in the amount of R$1,391,280, net of fees and related expenses. The Company clarifies that on December 21, 2021 the entire amount was deposited in the Company's account, after the presentation of a guarantee insurance. The Company reinforces that the decision that fixed the amount due in favor of Gerdau was maintained in all instances of the Judiciary Branch of the State of Rio de Janeiro, having been rejected the request for suspension by the Superior Court of Justice – STJ; and that it takes care of definitive execution, based on a final judicial enforcement order, no longer subject to deconstitution of any nature before the Judiciary, leaving only appeals and measures with remote possibilities of acceptance, in view of its only delaying nature.

The other lawsuits pending before the Judiciary, dealing with this subject, with final and unappealable decisions on the merits, favorable to the Company, total approximately R$73 million.

**V) Other contingent assets (Subsequent event)**

On February 2, 2023, Gerdau S.A. and its subsidiaries Gerdau Açominas S.A. and Gerdau Aços Longos S.A. were successful in a lawsuit of tax nature, regarding the right to PIS and COFINS credits on scrap purchases. Due to the final and unappealable decision of the court, which occurred on this date, Gerdau S.A. and its subsidiaries will be entitled to recognize a credit of approximately R$800 million in the statement of income (principal plus monetary restatement, minus legal fees and taxes). This amount, until then disclosed as Other contingent assets, reached the level of virtually certain, resulting in the recognition of the tax asset, which is expected to be monetized within a period of up to 5 years.

a) Post-employment defined benefit pension plan

The Company's Canadian and US subsidiaries sponsor defined benefit plans (Canadian Plan and American Plan), collectively referred to as the North American Plans, that cover substantially all their employees and provide supplemental benefits to employees during retirement.

The Company and its subsidiaries in Brazil sponsor a defined benefit pension plan (Brazilian plans), managed by Gerdau - Sociedade de Previdência Privada (GPrev), a closed supplementary pension plan, which were settled in 2010 and include only participants who decided not to transfer the reserve to a new defined contribution plan and, therefore, opted to maintain the benefit settled in the defined benefit plan, which has been adjusted by the INPC (National Consumer Price Index).

The assumptions adopted for pension plans can have a significant effect on the amounts disclosed and recorded for these plans. Due to the migration process and the closing of the Brazilian pension plans in 2010, the Company is not calculating the potential effects of changes in discount rates and expected return rate on assets for these plans. The potential effects of changes to the North American Plans on the Consolidated Statement of Income are presented below:

The investment strategy for the Brazilian Plan is based on a long-term macroeconomic scenario. This scenario assumes a reduction in Brazil's sovereign risk, moderate economic growth, stable levels of inflation, exchange rates and moderate interest rates.

The Canadian and American subsidiaries have 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 the Company. To reach 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. These subsidiaries retain 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 50% in shares, 40% in debt securities and 10% in alternative securities, and for Brazilian Plan it is close to 100% in fixed income.

IFRS requires the Company to disclose revenues from external customers for each product and service, or each group of similar products and services, unless the necessary information is not available and the cost to develop it would be excessive. Management does not consider this information useful for its decision-making process, because it would aggregate sales in different markets and in different currencies, subject to the effects of changes in exchange rates. Furthermore, the trends of steel consumption and the price dynamics of each product or group of products in different countries and different markets within these countries are poorly correlated

[**Table of Contents**](#TOC)

and, as a result, the information would not be useful and would not serve to reach any conclusions about historical trends. Considering this scenario and considering that the information of revenue from external customers by product and service is not maintained by the Company on a consolidated basis and the cost to obtain this information would be excessive compared to the benefits of the information, the Company does not present revenue by product and service.

**NOTE 29 — INSURANCE**

#### NOTE 30 — IMPAIRMENT OF ASSETS
The Company performs tests for impairment of assets, notably 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. The impairment test of these assets are assessed based on the analysis of facts or circumstances that may indicate the need to perform the impairment test and are performed at least annually, for groups of cash generating units containing goodwill, in December, or whenever changes in events or circumstances indicate that the goodwill and other long-lived assets may be impaired.

To determine the recoverable amount of each cash generating unit, the Company uses the discounted cash flow method, using as basis, financial and economic projections for each one. The projections are prepared by taking into consideration observed changes in the economic scenario in the market where the Company operates, as well as assumptions with respect to future results and the historical profitability of each segment.

The Company maintains its monitoring of the steel market in order to identify any deterioration, significant drop in demand from steel consuming sectors (notably automotive and construction), stoppage of industrial plants or significant changes in the economy or financial market that result in increased perception of risk or reduction of liquidity and refinancing capacity.

30.1 Other assets Impairment test

In 2022 and 2021, no impairment losses were recognized for other long-lived assets, notably property, plant and equipment.

In the fourth quarter of 2020, due to the lack of expectation of future use of some assets in two industrial plants, tests performed on other long-lived assets identified impairment losses in property, plant and equipment in the amount of R$411,925, of which R$69,570 in the Special Steel segment and R$342,355 in the North America segment, resulting from a recoverable amount below the book value. These losses were determined based on the difference between the book value and the recoverable amount of these assets, which represents their value in use (higher between the fair value net of disposal expenses and their value in use). These losses were recorded in the line of Impairment of non-financial assets in the Consolidated Statements of Income.

The post-tax discount rates used for this test are the same as presented in Note 30.2 of the goodwill impairment test.

30.2 Goodwill impairment test

The Company has four operating segments, which represents the lowest level in which goodwill is monitored by the Company. In 2022, 2021 and 2020, no impairment losses were recognized for goodwill.

The period for projecting the cash flows for the goodwill impairment test was five years. The assumptions used to determine the value in use based on the discounted cash flow method include analysis prepared in dollars, such as: projected cash flows based on management estimates for future cash flows, exchange rates, discount rates and growth rates. The cash flow projections already reflect

[**Table of Contents**](#TOC)

a competitive scenario, as well as macroeconomic challenges in some geographies in which the Company operates. The perpetuity was calculated considering stable operating margins, levels of working capital and investments. The perpetuity growth rates considered in the 2022 test were: a) North America: 3% (3% in December 2021); b) Special Steel: 3% (3% in December 2021); c) South America: 3% (3% in December 2021); and d) Brazil: 3% (3% in December 2021).

The post-tax discount rates used were determined taking into consideration market information available on the date of performing the impairment test. The Company adopted distinct rates for each business segment tested with the purpose of reflecting the differences among the markets in which each segment operates, as well as the risks associated to each of them. The post-tax discount rates used were: a) North America: 9.75% (9.50% in December 2021); b) Special Steel: 10.75% (10.50% in December 2021); c) South America: 18.00% (15.00% in December 2021); and d) Brazil 11.75%: (11.25% in December 2021). As required by the accounting standard, the Company made a calculation to determine the discount rates, before income tax and social contribution (gross rate of tax effects) and this calculation resulted in the following discount rates for each segment: a) North America 12.28% (12.05% in December 2021); b) Special Steel: 13.81% (13.29% in December 2021); c) South America: 26.47% (21.21% in December 2021); and d) Brazil: 15.56% (15.13% in December 2021).

Discounted cash flows are compared to the book value of each segment and result in the recoverable amount that exceeded book value as shown below: a) North America: R$10,426 million (R$5,769 million in 2021); b) Special Steel: R$5,299 million (R$4,238 million in 2021); c) South America: R$1,074 million (R$2,248 million in 2021); and d) Brazil: R$3,632 million (R$8,994 million in 2021).

The Company performed a sensitivity analysis in the assumptions of discount rate and perpetuity growth rate, due to the potential impact in the discounted cash flows.

An increase of 0.5 percentage points in the discount rate of each segment's cash flow would result in a recoverable amount that exceeded book value as shown below: a) North America: R$8,749 million (R$4,337 million in 2021); b) Special Steel: R$4,329 million (R$3,301 million in 2021); c) South America: R$953 million (R$2,057 million in 2021); and d) Brazil: R$2,306 million (R$7,582 million in 2021).

On the other hand, a decrease of 0.5 percentage points in the perpetuity growth rate of the cash flow of each business segment would result in a recoverable amount that exceeded book value as shown below: a) North America: R$9,161 million (R$4,679 million in 2021); b) Special Steel: R$4,586 million (R$3,545 million in 2021); c) South America: R$1,011 million (R$2,135 million in 2021); and d) Brazil: R$2,673 million (R$7,962 million in 2021).

The Company will maintain over the next year its constant monitoring of the steel market in order to identify any deterioration, significant drop in demand from steel consuming sectors (notably automotive and construction), stoppage of industrial plants or activities significant changes in the economy or financial market that result in increased perception of risk or reduction of liquidity and refinancing capacity. Although the projections made by the Company provide a more challenging scenario than that in recent years, the events mentioned above, if manifested in a greater intensity than that anticipated in the assumptions made by management, may lead the Company to revise its projections of value in use and eventually result in impairment losses.
