NOTE 7 – INCOME AND SOCIAL CONTRIBUTION TAXES

In Brazil, income taxes include federal income tax (IR) and social contribution (CS), which represents an additional federal income tax. The statutory rates for income tax and social contribution are 25% and 9%, respectively, and are applicable for the periods ended on March 31, 2023 and 2022. The foreign subsidiaries of the Company are subject to taxation at rates ranging between 23% and 35%. The differences between the Brazilian tax rates and the rates of other countries are presented under “Difference in tax rates in foreign companies” in the reconciliation of income tax and social contribution below.

a) Reconciliations of income and social contribution taxes at statutory rates to amounts presented in the Statement of Income are as follows:

	For the three-month period ended
	March 31, 2023			March 31, 2022
Income before income taxes		4,242,342			4,510,133

* On September 24, 2021, the Federal Supreme Court finalized the judgment of Topic 962, deciding unanimously that the IR and CS levy was not due on the amounts related to interests (Selic rate) on tax lawsuits. Thus, the effects of such judgment were considered to the tax calculation applied to the interests recorded in the period, related to the tax credit arising from the final and unappealable decision of the actions that discussed the inclusion of ICMS in the PIS/COFINS calculation basis.

Trade accounts payable - imports		1,261,079		1,724,019
		6,853,622		6,618,923

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 result in a relevant change in 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 March 31, 2023, 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.

NOTE 14 - FINANCIAL INSTRUMENTS

a) General considerations - Gerdau S.A. and its subsidiaries enter into transactions with financial instruments whose risks are managed through market strategies discussed and shared with senior management and in accordance with internal guidelines and control systems for exposure limits to them. All financial instruments are recorded in the accounting books and presented as short-term investments, trade accounts receivable, trade accounts payable – domestic market, trade accounts payable – debtor risk, trade accounts payable - imports, loans and financing, debentures, related parties, fair value of derivatives, obligations with FIDC, other current assets, other non-current assets, other current liabilities and other non-current liabilities.

The Company has derivatives and non-derivative instruments, such as the hedge for some operations under hedge accounting. These operations are intended to protect the Company against exchange rate fluctuations on foreign currency loans, interest rate and commodity prices fluctuations. These transactions are carried out considering direct active or passive exposures, without leverage.

b) Fair Value — the Fair Value of the financial instruments is as follows:

	March 31, 2023				December 31, 2022
	Book		Fair		Book		Fair
	value		value		value		value
Assets
Short-term investments		3,243,455		3,243,455		2,959,135		2,959,135

Other non current liabilities		505,729		505,729		533,681		533,681

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 14.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 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, 12 and 13). Total Capitalization is formed by the Total Debt (composed of the principal of the debt) and the Equity (Note 17). 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 12 and 13, respectively.

Sensitivity analysis:

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

Impacts on Statements of Income
Assumptions	Percentage of change			March 31, 2023		March 31, 2022
Foreign currency sensitivity analysis		5	%		69,854		85,712
Interest rate sensitivity analysis		10 bps			28,793		48,256
Sensitivity analysis of changes in prices of products sold		1	%		188,723		203,305
Sensitivity analysis of changes in raw material and commodity prices		1	%		114,566		115,876
Sensitivity analysis of currency forward contracts		5	%		5,767		728
Commodity contracts		5	%		1,010		18,862

Foreign currency sensitivity analysis: As of March 31, 2023, 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$ 69,854 (R$ 85,712 as of March 31, 2022). 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$ 28,793 as of March 31, 2023 (R$ 48,256 as of March 31, 2022) 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 12 and 13, 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 March 31, 2023, totals R$ 188,723 (R$ 203,305 as of March 31, 2022) and the variation in the price of raw materials and other inputs totals R$ 114,566 as of March 31, 2023 (R$ 115,876 as of March 31, 2022). 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$ 5,767 as of March 31, 2023 (R$ 728 as of March 31, 2022) 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 14.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$ 1,010 as of March 31, 2023 (R$ 18,862 as of March 31, 2022), 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 14.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.

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:

		Notional value		Amount receivable				Amount payable
Contracts	Position	March 31, 2023	December 31, 2022	March 31, 2023		December 31, 2022		March 31, 2023		December 31, 2022

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$ 129,992 for the three-month period ended on March 31, 2023 (gain of R$ 1,115,178 for the three-month period ended on March 31, 2022).

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 March 31, 2023, 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 March 31, 2023 and December 31, 2022, are as follows:

	Fair Value Measurements at Reporting Date Using
	Balance per financial statements				Quoted Prices in Non-Active Markets for Similar Assets (Level 2)

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.

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^st 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$ 577,534. 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$ 931,211. 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:

	March 31, 2023		December 31, 2022
Tax		1,722,258		1,603,136
Labor		70,978		67,911
Civil		162,890		154,852
		1,956,126		1,825,899

The balance of tax judicial deposits as of March 31, 2023 includes the amount of R$ 1,546,815 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. 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

In 2020, 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^th Specialized Panel of the Federal Regional Court of the 2^nd 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^nd 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 Company, in the 3^rd 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

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 recognized a credit of R$ 828 million in the statement of income (principal minus legal fees recognized in the line of Other Operating Income, plus monetary restatement recognized in the Tax credits monetary update line and deducted from taxes recognized in the income and social contribution taxes line). This amount, until then disclosed as Other contingent assets, reached the level of virtually certain, resulting in the recognition of the asset in Tax credits, which is expected to be monetized within a period of up to 5 years.

NOTES TO THE CONDENSED CONSOLIDATED INTERIM FINANCIAL STATEMENTS

as of March 31, 2023

(In thousands of Brazilian Reais – R$, unless otherwise stated)

(Unaudited) 

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 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 23 – IMPAIRMENT OF ASSETS

The impairment test of goodwill and other long-lived assets is tested based on the analysis and identification of facts or circumstances that may involve the need to perform the impairment test. The Company performs impairment tests of goodwill and other long-lived assets, based on projections of discounted cash flows, which take into account assumptions such as: cost of capital, growth rate and adjustments applied to flows in perpetuity, methodology for working capital determination, investment plans, and long-term economic-financial forecasts.

To determine the recoverable amount of each business segment, the Company uses the discounted cash flow method, taking as basis, financial and economic projections for each segment. The projections are updated to take into consideration any observed changes in the economic environment of the market in which the Company operates, as well as premises of expected results and historical profitability of each segment.

The impairment test of goodwill allocated to the business segments is carried out annually in December and it is anticipated if events or circumstances indicate that it is necessary. In the test carried out in the year 2022, the Company carried out a sensitivity analysis of the discount rate and perpetuity growth rate using the analysis of the scenario described above, given its potential impacts on cash flows, where an increase of 0.5% in the cash flow discount rate for each segment would result in an recoverable amount exceeding the carrying amount as shown below: a) North America: R$ 8,749 million; b) Special Steels: R$ 4,329 million; c) South America: R$ 953 million; and d) Brazil: R$ 2,306 million. On the other hand, a decrease of 0.5 % in the perpetuity growth rate of the cash flow of each business segment would result in a recoverable amount exceeding the book value as shown below: a) North America: R$ 9,161 million; b) Special Steels: R$ 4,586 million; c) South America: R$ 1,011 million; and d) Brazil: R$ 2,673 million.

The Company concluded that there are no indications that demand the performance of the impairment test of goodwill and other long-lived assets for the period ended on March 31, 2023.

The Company will maintain over 2023 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 relevant 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 challenging scenario, events that impact economic environment and business, 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.

NOTE 24 - SUBSEQUENT EVENTS

I) On April 28, 2023, the Company proposed the anticipation of the mandatory minimum dividend on income of the current fiscal year, stipulated in its Bylaws, to be paid in the form of interest on equity, which will be calculated and credited on the shareholding interest owned on May 15, 2023, in the amount of R$ 892.0 million (R$ 0.51 per common and preferred share), with payment on May 29, 2023, which was submitted and approved by the Board of Directors on May 2, 2023.
