Exhibit 99.1

GERDAU S.A.

Condensed consolidated

interim financial information

at September 30, 2006 and 2005

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Shareholders

Gerdau S.A.

We have reviewed the accompanying condensed consolidated balance sheets of Gerdau S.A. and its subsidiaries (the “Company”) as of September 30, 2006 and 2005, and the related condensed consolidated statements of income, of comprehensive income, of cash flows and of changes in shareholders’ equity for each of the three-month and nine-month periods ended September 30, 2006 and 2005.  This interim financial information is the responsibility of the Company’s management.

The review of the interim financial information of: (a) Gallatin Steel Company, a 50% owned joint venture, whose equity investment amounted to 1.1% and 1.1% of total consolidated assets as of September 30, 2006 and September 30, 2005, respectively, and whose equity in income amounted to 9.5% and 5.8%, and 4.6 % and 2.6% of income before taxes on income and minority interests for the three-month and nine-month periods ended September 30, 2006 and for the three-month and nine-month periods ended September 30, 2005, respectively; and (b) Aços Villares S.A. a subsidiary, whose total assets as of September 30, 2006, and net sales for the three-month and nine-month periods ended September 30, 2006, constituted 6.0%, 6.7 % and 6.5 %, respectively, of the related consolidated totals; have been carried out by other auditors.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States).  A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters.  It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States), the objective of which is the expression of an opinion regarding the financial statements taken as a whole.  Accordingly, we do not express such an opinion.

Based on our review and the review performed by the other auditors, we are not aware of any material modifications that should be made to the accompanying condensed consolidated interim financial information for it to be in conformity with accounting principles generally accepted in the United States of America.

We previously audited in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet as of December 31, 2005, and the related consolidated statements of income, of comprehensive income, of changes in shareholders’ equity and of cash flows for the year then ended (not presented herein) of Gerdau S.A. and its subsidiaries, and in our report dated May 2, 2006 we expressed an unqualified opinion on those consolidated financial statements.  In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2005, is fairly stated in all material respects in relation to the consolidated balance sheet from which it has been derived.

2.1          Accounting practices

The accompanying condensed consolidated financial information has been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”), which differ in certain aspects from the accounting practices adopted in Brazil (“Brazilian GAAP”) applied by the Company in the preparation of its statutory financial statements and for other legal and regulatory purposes. The consolidated financial statements for statutory purposes are prepared in Brazilian reais.

The condensed consolidated financial information as of and for the three-month and nine-month periods ended September 30, 2006 and 2005 is unaudited.  However, in the opinion of management, this financial information includes all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the consolidated financial position, results of operations and cash flows for the interim periods presented.  The results for the three-month period and nine-month period ended September 30, 2006 are not necessarily indicative of the results to be expected for the entire year.

This condensed financial information has been prepared on substantially the same basis as the consolidated financial statements as of and for the year ended December 31, 2005 and should be read in conjunction therewith.

The year-end condensed balance sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

2.2          Recently issued accounting standards

In February 2006, the Financial Accounting Standards Board (“FASB”) issued Statement on Financial Accounting Standards (“SFAS”) No. 155 “Accounting for Certain Hybrid Financial Instruments”. SFAS No. 155 amends SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities”, and SFAS No. 140, “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities”. SFAS 155 resolves issues addressed in Statement 133 Implementation Issue No. D1, “Application of Statement 133 to Beneficial Interest in Securitized Financial Assets”.

SFAS 155:

a.Permits fair value remeasurement for any hybrid financial instrument that contains an embedded derivative that otherwise would require bifurcation;

b.Clarifies that interest-only strips and principal-only strips are not subject to the requirements of Statement 133;

c.Establishes a requirement to evaluate interests in securitized financial assets to identify interests that are freestanding derivatives or that are hybrid financial instruments that contain en embedded derivative requiring bifurcation;

d.Clarifies that concentrations of credit risk in the form of subordination are not embedded derivatives;

e.Amends Statement 140 to eliminate the prohibition on a qualifying special purpose entity from holding a derivative financial instrument that pertains to a beneficial interest other than another derivative financial instrument.

This Statement is effective for all financial instruments acquired or issued after the beginning of an entity’s first fiscal year that begins after September 15, 2006. The impact of these statement on the Company is dependent on events that could occur in the future periods, and as such, an estimate of the impact cannot be determined until these future events occurs.

In March 2006, the FASB issued SFAS No. 156 “Accounting for Servicing of Financial Assets”. SFAS 156 amends SFAS No. 140, that establishes, among other things, the accounting for all separately recognized servicing assets and servicing liabilities. SFAS 156 amends SFAS 140 to require that all separately  recognized servicing assets and servicing liabilities be initially measured at fair value, if practicable. SFAS 156 permits, but does not require, the subsequent measurement of separately recognized servicing assets and servicing liabilities at fair value. An entity that uses derivative instruments to mitigate the risks inherent in servicing assets and servicing liabilities is required to account for those derivative instruments at fair value. Under this Statement, an entity can elect subsequent fair value measurement to account for its separately recognized servicing assets and servicing liabilities. By electing that option, an entity may simplify its accounting because this Statement permits recognition of the potential offsetting changes in fair value of those servicing assets and servicing liabilities and derivative instruments in the same accounting period. An entity shall adopt this Statement as of the beginning of its fiscal year that begins after September 15, 2006. Earlier adoption is permitted as of the beginning of an entity’s fiscal year, provided the entity has not yet issued financial statements, including interim financial statements, for any period of that fiscal year. The impact of these statement on the Company is dependent on events that could occur in the future periods, and as such, an estimate of the impact cannot be determined until these future events occurs.

In April 2006, the FASB issued FASB Staff Position No. FIN 46(R)-6, “Determining the Variability to Be Considered in Applying FASB Interpretation No. 46(R)” (“FSP FIN 46(R)-6”). FSP FIN 46(R)-6 requires that the determination of the variability to be considered in applying FIN 46R be based on an analysis of the design of the entity. In evaluating whether an interest with a variable interest entity creates or absorbs variability, FSP FIN 46(R)-6 focuses on the role of a contract or arrangement in the design of an entity, regardless of its legal form or accounting classification. Guidance in FSP FIN 46(R)-6 must be applied prospectively

F-10

beginning September 1, 2006 to all entities to which the Company first becomes involved with and to all entities previously required to be analyzed under FIN 46R when a reconsideration event occurs under paragraph 7 of FIN 46R. The impact of these statement on the Company is dependent on events that could occur in the future periods, and as such, an estimate of the impact cannot be determined until these future events occurs.

In July 2006, the FASB released FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an interpretation of FASB Statement No. 109” (FIN 48). FIN48 prescribes a comprehensive model for the financial statement recognition, measurement, presentation and disclosure of income tax uncertainties with respect to positions taken or expected to be taken in income tax returns. The Company will adopt the guidance in FIN 48 as from January 1, 2007. Management is currently evaluating the effect of SFAS 157 on the Company’s financial condition and results of operations.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements”. SFAS 157 defines fair value, establishes a framework for measuring fair value under generally accepted accounting principles and enhances disclosures about fair value measurements. SFAS 157 retains the exchange price notion and clarifies that the exchange price is the price that would be received for an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants on the measurement date. SFAS 157 is effective for the Company’s financial statements for the year beginning on January 1, 2008, with earlier adoption permitted. Management is currently evaluating the effect of SFAS 157 on the Company’s financial condition and results of operations. The Company is in the process of evaluating the financial impact of adopting SFAS No. 157.

In September 2006, the FASB issued Statement No. 158 “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R)”. Among other items, SFAS No 158 requires recognition of the overfunded or underfunded status of an entity’s defined benefit postretirement plan as an asset or liability in the financial statements, requires the measurement of defined benefit postretirement plan assets and obligations as of the end of the employer’s fiscal year, and requires recognition of the funded status of defined benefit postretirement plans in other comprehensive income. The recognition of the funded status of the benefits is effective for fiscal years ending after December 15, 2006 on a prospective basis. The requirement to measure defined benefit plans assets and liabilities is effective for the Company for the year ending December 31, 2008. Management is currently evaluating the effect of SFAS 158 on the Company’s financial condition.

2.3          Currency translation

The Company has selected the United States dollar as its reporting currency. The U.S. dollar amounts have been translated following the criteria established in SFAS No. 52, “Foreign Currency Translation” from the financial statements expressed in the local currency of the countries where Gerdau and each subsidiary operates.

The Company’s main operations are located in Brazil, the United States, Canada, Spain and Chile. The local currency is the functional currency for those operations. These financial statements, except for those of the subsidiaries located in the United States which already prepare their financial statements in United States dollars, are translated from the functional currency into the US dollar. Assets and liabilities are translated at the exchange rate in effect at the end of each period. Average exchange rates are used for the translation of revenues, expenses, gains and losses in the statement of income. Capital contributions, treasury stock transactions and dividends are translated using the exchange rate as of the date of the transaction. Translation gains and losses resulting from the translation methodology described above are recorded directly in “Cumulative other comprehensive loss” within shareholders’ equity. Gains and losses on foreign currency denominated transactions are included in the consolidated statement of income.

2.4          Controlling shareholder

As of September 30, 2006, the Company’s parent, Metalúrgica Gerdau S.A. (“MG”, collectively with its subsidiaries and affiliates, the “Conglomerate”) owned 42.99% (December 31, 2005 and September 30, 2005 - 44.80%) of the total capital of the Company.  MG’s share ownership consisted of 75.73% (in all periods presented) of the Company’s voting common shares and 25.10% (December 31, 2005 and September 30, 2005 — 28.38%) of its non-voting preferred shares.

2.5          Stock Based Compensation Plans

Gerdau Ameristeel Corp (“Gerdau Ameristeel”) and its subsidiaries and Gerdau S.A. maintain stock based compensation plans.  The Company accounts for the stock-based compensation plans as from January 1, 2006 under SFAS 123 — R (“SFAS 123R”) “Shared-based payment”. SFAS 123R addresses the accounting for employee stock options and eliminates the alternative use of the intrinsic value method of accounting that was provided in Statement 123 as originally issued.  This statement requires a public entity to measure the cost of employee services received in exchange for an award of equity instruments, based on the grant-date fair value of the award. That cost will be recognized over the period during which an employee is required to provide services in exchange for the award (vesting period). The grant-date fair value of employee share options and similar instruments is estimated using option-pricing models adjusted to the unique characteristics of those instruments.

The Company has applied the modified prospective application method to account for the implementation of SFAS 123R, which consists on recognizing costs of services rendered as from January 1, 2006 according to the grant-date fair value of stock options instruments, but does not require to restate previous year financial statements, and instead requires pro forma disclosures of net income and earnings per share for the effects on compensation had the grant-date fair value been adopted in prior periods. Under this transition method, compensation cost for stock options plans as from January 1, 2006, include the applicable amount of: (a) compensation cost for all share based instruments granted prior to, but not yet vested, as of January 1, 2006 (based on the grant-date fair value in accordance with the provisions of SFAS 123), and (b) compensation cost for all share based instruments granted after January 1, 2006 (based on the grant-date fair value estimated in accordance with the new provisions of SFAS 123R).

Through December 31, 2005, the Company applied the intrinsic value method established by Accounting Principles Board (“APB”) Opinion Nº 25, “Accounting for Stock Issued to Employees” to account compensation for stock based compensation.

The Company and its subsidiary Gerdau Ameristeel have several stock based compensation plans. A brief summary of those plans is presented below:

Gerdau Plan

The Extraordinary Stockholders’ General Meeting of Gerdau held on April 30, 2003 decided, based on a plan approved by an Annual Stockholders’ meeting and up to the limit of authorized capital, to grant options to purchase shares to management, employees or individuals who render services to the Company or to entities under its control, and approved the creation of the “Long Term Incentive Program”. Under the plan, the Board of Directors may grant options to purchase shares at an exercise price established by the Board of Directors and that can be exercised after a vesting period and up to 5 years after vested.

F-12

Gerdau Ameristeel Plans

(a)           For the year ended December 31, 2004, Gerdau Ameristeel’s Human Resources Committee adopted the 2004 Long-Term Incentive Stakeholder Plan (the “2004 Stakeholder Plan”). The 2004 Stakeholder Plan is designed to reward the  senior management of Gerdau Ameristeel with a share of Gerdau Ameristeel’s profits after a capital charge. Awards, calculated in dollars, are invested in phantom common shares at a price equal to the closing price of the common shares on the New York Stock Exchange on the date of the grant, and vest in equal installments on each of the four anniversary dates of the date of grant. Payouts will be calculated based on the closing price of Common Shares of Gerdau Ameristeel on the New York Stock Exchange on the vesting date and will be paid as soon as practicable following vesting. An award of approximately $14.0 million was earned by participants in the 2004 Stakeholder Plan for the year ended December 31, 2004 and was granted on March 1, 2005. The award is being accrued over the vesting period. No further awards will be made under this plan.

(b)          For the year commencing January 1, 2005, the Human Resources Committee adopted the 2005 Long-Term Incentive Plan (the “2005LTI Plan”). The 2005 LTI Plan is designed to reward the senior management of Gerdau Ameristeel with bonuses based on the achievement of return on capital invested targets. Bonuses which have been earned are awarded after the end of the year in the form of cash, stock appreciation rights (“SARs”), and/or options. The portion of any bonus which is payable in cash is to be paid in the form of phantom stock. The number of shares of phantom stock awarded to a participant is determined by dividing the cash bonus amount by the fair market value of a Common Share of Gerdau Ameristeel at the date the award of phantom stock is made based on the weighted average trading price of the Common Shares on the New York Stock Exchange. Phantom stock and SARs vest 25% on each of the first four anniversaries of the date of the award.Phantom stock will be paid out following vesting on the basis of a cash payment. The number of options awarded to a participant is determined by dividing the non-cash amount of the bonus by the fair market value of a Common Share at the date the award of the options is made. The value of the options is determined by the Committee based on a Black Scholes or other method for determining option values). Options vest 25% on each of the first four anniversaries of the date of the award. Options may be exercised following vesting. Options have a maximum term of 10 years. The maximum number of options able to be granted under this plan is 6,000,000. An award of approximately $3.0 million was earned by participants in 2005 and is payable 50% in options and 50% in phantom stock. On March 20, 2006, Gerdau Ameristeel issued 202,478 options under this plan. The award is being accrued over the vesting period.

(c)           Under Gerdau Ameristeel’s Stock-Based Option Plan, Gerdau Ameristeel was permitted to grant options to employees and directors to acquire up to a maximum of 3,041,335 common shares. The exercise price was based on the closing price of common shares on the trading date previous to the date the options are issued. The options have a maximum term of 10 years, have a vesting term of various periods as determined by the Plan administrator at the time of grant, and are exercisable in installments. The remaining 501,000 options outstanding under this plan expire on various dates up to April 13, 2008. No grants have been made under this plan since 1998.

(d)          A subsidiary of the Company, Gerdau Ameristeel US Inc. (“Ameristeel”), had several stock compensation plans for its employees. Under the terms of the Transaction Agreement relating to the 2002 merger with Co-Steel Inc., minority shareholders of Ameristeel exchanged shares of Ameristeel stock and options for stock and options of Gerdau Ameristeel at an exchange rate of 9.4617 shares and options of Gerdau Ameristeel for each Ameristeel share or option. This exchange took place on March 31, 2003. All amounts presented in the discussion below have been restated to reflect the historical shares at the exchanged value. In September 1996, Ameristeel’s Board of Directors approved the Ameristeel Corporation Equity Ownership Plan (the “Equity Ownership Plan”), which provided for grants of common stock, options to purchase common stock and SARs. After conversion into common shares of Gerdau Ameristeel, the maximum number of common shares issuable under the plan is 4,152,286. All issued options and shares of issued common stock become one-third vested two years from the grant date, and one third in each of the subsequent two years from the grant

F-13

date. All grants were at the estimated fair market value of the common stock on the grant date, determined based on an independent appraisal as of the end of the previous year-end. Options may be exercised for 10 years from the grant date. In July 1999, Ameristeel’s Board of Directors approved a Stock Purchase/SAR Plan (the “SAR Plan”) available to essentially all employees. The SAR Plan authorized 946,170 shares of common stock to be sold to employees during three offering periods, July through September in each of 1999, 2002 and 2005. Employees who purchased stock were awarded stock appreciation rights (“SARs”) equal to four times the number of shares purchased. SARs were granted at fair value at the date of the grant. The SARs become exercisable at the rate of 25% annually from the grant date and may be exercised for 10 years from the grant date. The SARs are recorded as a liability and benefits are charged to expense. In July 2002, Ameristeel’s Board of Directors approved the issuance of SARs that were granted to officers with exercise prices granted at fair value at the date of grant. 6,244,722 SARs were authorized and issued. The SARs become one-third vested two years from the grant date, and one third in each of the subsequent two years from the grant date. SARs may be exercised for 10 years from the grant date. The SARs are recorded as a liability and benefits are charged to expense. In the nine months ended September 30, 2006, the Company recognized $400 of stock compensation costs related to the options issued during the first quarter. The remaining unrecognized compensation cost related to unvested awards at September 30, 2006 was approximately $500 and the weighted-average period of time over which this cost will be recognized is 3 years.

(e)           Under the employment agreement of the Gerdau Ameristeel’s President and Chief Executive Officer (the “Executive”), effective as of June 1, 2005, the Executive is entitled to participate in a long-term incentive arrangement which provides that Gerdau Ameristeel will deliver 1,749,526 Common Shares as long as the Executive is Chief Executive Officer of Gerdau Ameristeel on June 1, 2015.In addition, the Executive is entitled to an amount of Common Shares equal to the amount of cash dividends payable on such Common Shares, plus an amount in cash equal to 75% of the amount by which US$25 million exceeds, on June 1, 2015, the value of the 1,749,526 Common Shares, the amount of cash dividends payable on such Common Shares, plus the value of certain shares of Gerdau S.A. stock or American Depository Receipts of Gerdau S.A. awarded pursuant to the Executive’s  separate employment agreement with Gerdau S.A., dated as of June 1, 2005, as long as the Executive is Chief Executive Officer of the Company on June 1, 2015.In order to secure Gerdau Ameristeel’s obligations to deliver such Common Shares, the subsidiary will deposit in trust such Common Shares over a period beginning at the end of the first year following the commencement of the start date and ending 10 years thereafter or such earlier date if the Executive is separated from service in certain circumstances. In the event that the Executive has a separation from service prior to June 1, 2015, due to termination without cause, termination by the Executive for any reason or termination for death or disability, the Executive will, in each instance, be entitled to a calculated portion of the Executive’s long-term incentive.  The award is being accrued over the service period.  During the nine months ended September 30, 2006, 240,907 shares were issued to the trust under this agreement. Gerdau S. A. has deposited 275,050 preferred shares of its own emission in the same trust

Methodology and assumptions used to estimate grant-date fair value

The Company has selected the Black-Scholes model to estimate the grant-date fair value of stock based compensation. Under SFAS 123R the Company is required to estimate forfeitures when determining the stock based compensation expense as opposed to recognizing the forfeitures and the corresponding reduction in expense when they occur. The following weighted-average assumptions were used to estimate the compensation expense following the fair value method for compensation in stock of Gerdau S.A. and of Gerdau Ameristeel Corp., as appropriate.

Assumptions for options granted during the nine-months ended September 30, 2006:

2.7          Acquisitions

(a) Corporación Sidenor S.A.

On January 10, 2006 the Company concluded the acquisition of 40% of Corporación Sidenor S.A. (“Sidenor”), a Spanish steel producer with operations in Spain and Brazil. The Santander Group, the Spanish financial conglomerate, and an entity owned by executives of Sidenor contemporaneously acquired 40% and 20% of Sidenor, respectively. Purchase price for the acquisition of 100% of Sidenor consists of a fixed price of Euro 443,820 plus a variable contingent price which is payable only by the Company. The fixed price paid by the

F-18

Company on January 10, 2006 for its 40% interest in Sidenor amounted to Euro 165.828 (US$ 200,082). Santander Group holds a put option to sell their interest in Sidenor to the Company, after 5 years from the purchase, at a fixed price plus accrued interests computed using a fixed interest rate. Also, the Company has agreed to guarantee to the Santander Group the payment of an agreed amount (equal to the fixed price under the put option referred to above plus accrued interest computed using the same fixed interest rate) after 6 years from the purchase in the event that Santander Group has not sold the shares acquired up to such date or, if the Santander Group sells its interest at a price higher or lower than the agreed amount the difference will be paid by Santander Group to the Company or by the Company to Santander Group, respectively. The guarantee may be exercised by the Santander Group at any time after 6 years.

As of September 30, 2006, certain tax credits in the Spanish operation of Sidenor have been used. Part of the contingent variable price was dependent on the use of such tax credits and the Company is contractually obligated to pay to the former shareholders of Sidenor an amount equivalent to 70% of the tax credits used. As a result of this, the Company will make an additional payment of Euro 24,605 (US$29,817), which was recorded as an additional purchase price. The amount payable does not accrue interest and its fair value has been estimated at Euro 19,930 (US$ 24,152), which was recorded as additional purchase price consideration. During the third quarter ended September 30, 2006, the Company has paid 3,098 euros (US$ 3,929) regarding the use of those tax credits.

The Company has concluded that Corporación Sidenor is a variable interest entity (VIE) as defined by FIN 46(R) “Consolidation of Variable Interest Entities” and that the Company is the primary beneficiary. As a result, as from the acquisition date the Company has consolidated Corporación Sidenor and its subsidiaries which include Aços Villares S.A., a Brazilian specialty steel producer on which Corporación Sidenor has a 58% voting interest.

The Company has made a preliminary computation of the estimated fair value of assets and liabilities of Corporación Sidenor and its subsidiaries. The Company expects to complete a comprehensive analysis of the fair value of assets acquired and liabilities assumed until December 31, 2006. According to the preliminary computation of estimated fair value of assets and liabilities of Corporación Sidenor and its subsidiaries, the Company has concluded there is no goodwill on this acquisition. During the three months ended September 30, 2006 the Company has finalized the appraisal of property and equipment acquired for Corporación Sidenor and Forjanor S.L. (but not yet for Aços Villares which is expected to be finalized by year-end); the recognition of the effect of such appraisal have modified the amounts allocated on a preliminary basis as of June 30, 2006, as follows:

As result of the recognition of the appraisal referred to above, the amount of goodwill originally determined as of June 30, 2006 has been modified to an excess of fair value of assets acquired and liabilities assumed in relation to the purchase price which was allocated to reduce the value of long-lived assets acquired.

The Company’s  obligation  to purchase from  Santander Group its 40% interest in Corporación Sidenor is recorded in Minority Interest. As of September 30, 2006, such obligation amounts to $256,220.

6Commitments and contingencies

The Company is party to claims with respect to certain taxes, civil and labor matters. Management believes, based in part on advice from legal counsel, that the provision for contingencies is sufficient to meet probable and reasonably estimable losses from unfavorable rulings, and that the ultimate resolution will not have a significant effect on the consolidated financial position as of September 30, 2006, although it may have a significant effect on future results of operations or cash flows.

The following table summarizes the contingent claims and related judicial deposits:

	Contingencies			Judicial deposits
	September 30,		December	September 30,		December
Claims	2006	2005	31, 2005	2006	2005	31, 2005
Tax	133,444	87,892	103,345	52,916	55,996	52,548

	188,110	111,868	127,849	76,112	61,160	62,186

Probable losses on tax matters, for which a provision was recorded

All contingencies described in the section below correspond to instances where the Company is challenging the legality of taxes and contributions. The description of the contingent losses includes a description of the tax or contribution being challenged, the current status of the litigations as well as the amount of the probable loss which has been provided as of September 30, 2006.

·Of the total provision, $36,839 relates to a provision recorded by the subsidiary Gerdau Açominas on demands made by the Federal Revenue Secretariat regarding Import Taxes, Taxes on Industrialized Products (“IPI — Imposto sobre Produtos Industrializados”) and related legal increases, due to transactions carried out under drawback concession granted and afterwards annulled by DECEX (Foreign Operations Department). The Federal Revenue Secretariat claims these operations were not in conformity with the legislation. Management does not agree with the administrative decision which has annulled the drawback concession and believes all transactions were carried out under the law. The Company has proposed an injunction on this issue, and now this matter is under analysis of Superior Court of Justice (“Superior Tribunal de Justiça — STJ”).

·$22,268 related to amounts for State Value Added Tax  (“Imposto Sobre Circulação de Mercadorias e Serviços” - ICMS), the majority of which is related to credit rights involving the Finance Secretary and the State Courts of First Instance in the state of Minas Gerais.

·$3,373 related to Social Contribution on Net Income (“Contribuição Social Sobre o Lucro”) (CSSL). The amounts refer to challenges of the constitutionality of the contribution in 1989, 1990 and 1992. Some proceedings are pending decision, most of them in the Superior Courts.

·$9,196 related to Corporate Income Tax (“Imposto Renda de Pessoa Jurídica - IRPJ), for which administrative appeals have been filed.

·$15,236 corresponds to contributions due to the social security authorities which are related to suits for annulment by the Company in progress in the Federal Court of First Instance in the state of Rio de Janeiro. The

F-26

amount provided also refers to lawsuits questioning the position of the National Institute of Social Security (“Institutio Nacional da Seguridade Social” - INSS) in terms of charging INSS contributions on profit sharing payments made by the subsidiary Gerdau Açominas and several INSS assessments due to services contracted from third parties, in which the INSS accrued debts related to the last ten years and assessed Gerdau Açominas as jointly responsible. The assessments were reaffirmed by the INSS when challenged by the Company and are currently being challenged by Gerdau Açominas in annulment proceedings with deposit in court of the amount being discussed, since the Company understands that the right to set up part of the credits had expired, and that, in any event, the Company is not responsible.

·$15,561  related to the Emergency Capacity Charge (“Encargo de Capacidade Emergencial” — ECE), as well as $9,896 related to the Extraordinary Tariff Recomposition (“Recomposição Tarifária Extraordinária — RTE), which are charges included in the electric energy bills of the Company’s plants. According to the Company, these charges are of a tax nature and, as such, are incompatible with the National Tax System provided in the Federal Constitution. For this reason, the constitutionality of this charge is being challenged in court. The lawsuits are in progress in the Federal Justice of the First Instance of the states of São Paulo and Rio Grande do Sul, as well as in the Federal Regional Courts of the 1st , 2nd, , 3 rd , 4 th and 5 th Regions. The Company has fully deposited in court the amount of the disputed charges.

·The Company is also defending other taxes in the amount of $21,076, for which a provision has been made following advice from Company’s legal counsel.

Possible or remote losses on tax matters for which no provision was recorded

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

·The Company is defendant in debt foreclosures filed by the State of Minas Gerais to demand ICMS credits arising mainly from the sales of products to commercial exporters. The total amount of the processes is $15,381. The Company did not set up a provision for contingency in relation to these processes, since it considers this tax is not payable, because products for export are exempted from ICMS.

·The Company and its subsidiary Gerdau Açominas are defendants in tax foreclosures filed by the state of Minas Gerais, which demand ICMS credits on the export of semi-finished manufactured products. The total amount demanded is $132,132. The Company did not set up a provision for contingency in relation to these processes since it considers the tax as not payable, because the products do not fit in the definition of semi-finished manufactured products defined by the federal complementary law and, therefore, are not subject to ICMS.

·The Company has entered into Fiscal Recovering Program (“Programa de Recuperação Fiscal” — REFIS) on December 6, 2000, which allowed the Company to pay PIS and Cofins debts on installments. Brazilian fiscal authorities are discussing the legality of $18,452 in credits acquired from third parties and used to offset fines and interests incurred by the Company, under the terms of the Program. Brazilian fiscal authorities understand those credits should be offset in first place against taxes due by the owners of the credits, and only after that they would be eligible to be transferred to third parties, but this understanding is based only on a Resolution of the Management Committee of REFIS, and not in the relevant law, according to Company’s legal counsel. On May 2006, the Company has obtained a favorable outcome on the judgment of the injunction conducted by the Company.

Unrecognized contingent tax assets

Management believes the realization of certain contingent assets is possible. However, no amount has been recognized for these contingent tax assets that would only be recognized upon final realization of the gain:

·Among them is a court-ordered debt security issued in 1999 in favor of the Company by the state of Rio de Janeiro in the amount of $12,225 arising from an ordinary lawsuit regarding non-compliance with the Loan Agreement for Periodic Execution in Cash under the Special Industrial Development Program - PRODI. Due to the default by the State of Rio de Janeiro and the non-regulation of the Constitutional Amendment 30/00, which granted the government a ten-year moratorium for the payment of securities issued to cover court-order debt not related to food, the Company understands realization of this credit in 2006 or in the following years is only possible.

·The Company and its subsidiary Gerdau Açominas  and Margusa — Maranhão Gusa S.A. are claming recovery of IPI premium credits. Gerdau S.A. and its subsidiary Margusa — Maranhão Gusa S.A. have filed administrative appeals, which are pending judgment. With regard to the subsidiary Gerdau Açominas S.A., the claims were filed directly to the courts and a decision unfavorable to Gerdau Açominas was issued and has been appealed by Gerdau Açominas. The Company estimates a credit in the amount of $153,577.

Labor contingencies

The Company is also defending labor proceedings, for which there is a provision as of September 30, 2006 of $42,628. None of these lawsuits refers to individually significant amounts, and the lawsuits mainly involve claims due to overtime, health and risk premiums, among others. The balances of deposits in court related to labor contingencies, at September 30, 2006, totaled $15,098.

Other contingencies

The Company is also defending in court civil proceedings arising from the normal course of its operations and has accrued $10,927 for these claims. Escrow deposits related to these contingencies, at September 30, 2006, amount to $8,099.

Other contingent liabilities with remote or possible chances of loss, involving uncertainties as to their occurrence, and therefore, not included in the provision for contingencies, are comprised by:

·An antitrust process involving Gerdau S.A. related to the representation of two civil construction syndicates in the state of São Paulo that alleged that Gerdau S.A. and other long steel producers in Brazil divide customers among them, violating the antitrust legislation. After investigations carried out by the National Secretariat of Economic Law — (“Secretaria de Direito Econômico”- SDE) and based on public hearings, the SDE is of the opinion that a cartel existed. This conclusion was also supported by an earlier opinion of the Secretariat for Economic Monitoring (“Secretaria de Acompanhamento Econômico” — SEAE). The process was sent to the Administrative Council for Economic Defense — (“Conselho Administrativo de Defesa Econômica” — CADE), for judgment.

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

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

On July 26, 2006, due to a reversal of terms of the decision pronounced by CADE, the Company appealed to the Justice using a new ordinary lawsuit which point out irregularities in the administrative procedures

F-28

conducted by CADE. The federal judge designated for the analysis of the fact decided, on August, 30, 2006 to suspend the effect of CADE decision until  a final decision is taken with respect to this judicial process. This ordinary lawsuit proceeds together with the injunction originally proposed on CADE.

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

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

·There is a civil lawsuit filed against Gerdau Açominas , regarding the termination of a contract for the supply of slag and indemnities for losses and damages. The amount of the claim, at September 30, 2006 was approximately $22,056. Gerdau Açominas  contested all bases for the lawsuit and filed a counterclaim for the termination of the contract and indemnity for breach of contract. The judge declared the contract to be terminated, since such demand was common to both parties. With regards to the remaining discussion, the judge understood that both parties were at fault and judged unfounded the requests for indemnity. This decision was maintained by the Court of Civil Appeals of the state of Minas Gerais (CCPMG) and is based on expert evidence and interpretation of the contract. The process went to the High Court of Justice and returned to CCPMG for the judgment of the appeal. Gerdau Açominas  believes that a loss from the case is remote, since it understands that a change in the judgment is unlikely.

Insurance claim

A civil lawsuit was filed by Sul América Cia Nacional de Seguros on August 4, 2003 against Gerdau Açominas  and Banco Westdeustsche Landesbank Girozentrale, New York Branch (WestLB), for the payment of $15,814 which was deposited in court to settle an insurance claim made by Gerdau Açominas. The insurer pleads uncertainty in relation to whom payment should be made and alleges that the Company is resisting in receiving and settling it. The lawsuit was contested by both the bank (which claimed having no right over the amount deposited, solving the question raised by Sul América) and the Company (which claimed inexistence of uncertainty and justification to refuse the payment, since the amount owed by Sul América is higher than stated). After this pleading, Sul América claimed fault in the bank’s representation, and this matter is therefore already settled, which resulted collection by Gerdau Açominas in December 2004 of the amount deposited by the insurer. Gerdau Açominas has also claimed on a judicial proceeding the amount recognized by the insurers, previous to the civil lawsuit commented above. These proceedings are included in the main lawsuit, and the Company expects to be successful with this claim.

The civil lawsuits arise from the accident on March 23, 2002 with the blast furnace regenerators of the Presidente Arthur Bernardes mill, which resulted in stoppage of several activities, material damages to the steel mill equipment and loss of profits. The equipment, as well as loss of profits arising from the accident, was covered by an insurance policy. The report on the event, as well as the loss claim was filed with IRB - Brasil Resseguros S.A., and the Company received an advance of $28,516 during 2002.

In 2002, a preliminary estimate of indemnities related to the coverage of loss of profits and material damages, in the total amount of approximately $50,593, was recorded, based on the amount of fixed costs incurred during the period of partial stoppage of the steel mill and on the expenses incurred to recover the equipment temporarily. This estimate is close to the amount of the advance received, plus the amount proposed by the insurance company as a complement for settling the indemnity. Subsequently, new amounts were added to the discussion, as demonstrated in the Company’s appeal, although they were not accounted for as well as other

F-29

costs to recover damage caused by the accident. When confirmed, those recoveries will be recorded in the financial statements. The suit meets with the engineering and accounting skills in progress, when the pointed value will be demonstrated judicially by the Company.

Based on the opinion of its legal advisors, management considers that losses from other contingencies are remote, and that eventual losses would not have a material adverse effect on the consolidated results of operations, consolidated financial position of the Company or its future cash flows.

7Shareholders’ equity

7.1Share capital

As of September 30, 2006, 231,607,008 shares of Common stock and 435,986,042 shares of Preferred stock had been issued. The share capital of the Company is comprised of Common shares and Preferred shares, all without par value. The authorized capital of the Company is comprised of 400,000,000 Common shares and 800,000,000 Preferred shares. Only the Common shares are entitled to vote. There are no redemption provisions associated with the Preferred shares.  The Preferred shares have preferences in respect of the proceeds on liquidation of the Company.

At a meeting of shareholders held on March 31, 2006, shareholders approved a bonus to both common and preferred shareholders of 50 shares per 100 shares held with the stock bonus made  effective on April 12, 2006. On the same date the Company increased capital with capitalization of reserves, in the total amount of $1,220,231 ($796,898 for preferred shares and $423,333 for common shares). Preferred shares and common shares resulting from the capitalization were issued through the stock bonus referred above.

At September 30, 2006, the Company held in treasury 5,120,775 preferred shares at a cost of $46,167 (4,568,543 preferred shares at September 30, 2005 and December 31, 2005, after giving retroactive effect of stock bonus approved on March 31, 2006 both at a cost of $21,951).

7.2Dividends

On August 14, 2006, the Company has credited $106,643 as dividends as an anticipation of the minimum statutory dividend of the fiscal year 2006.

Brazilian corporations are permitted to distribute interest on equity, similar to a dividend distribution, which is deductible for income tax purposes. The amount payable may not exceed 50% of the greater of net income for the year or retained earnings, as measured under Brazilian Corporate Law. It also may not exceed the product of the Taxa de Juros Longo Prazo (“TJLP”) (long-term interest rate) and the balance of shareholders’ equity, as measured under Brazilian Corporate Law.

Payment of interest on equity is beneficial to the Company when compared to making a dividend payment, since it is deductible for income tax purposes. The related tax benefit is recorded in the consolidated statement of income. Income tax is withheld from the stockholders with respect to interest on equity at the rate of 15%.

8Earnings per share (EPS)

Pursuant to SFAS No. 128, “Earnings per Share” the following tables reconcile net income to the amounts used to calculate basic and diluted EPS. Computations of EPS presented below have been retroactively adjusted to reflect stock bonus approved on March 31, 2006 to both common and preferred shareholders of 50 shares per 100 shares held.

9Derivative instruments

The use of derivatives by the Company is limited. Derivative instruments are used to manage clearly identifiable foreign exchange and interest rate risks arising out of the normal course of business.

Gerdau and Gerdau Açominas

As part of its normal business operations, Gerdau and Gerdau Açominas have obtained U.S. dollar denominated debt at fixed rates which exposes them to market risk from changes in foreign exchange and interest rates. Changes in the rate of the Brazilian real against the U.S. dollar expose Gerdau and Gerdau Açominas to foreign exchange gains and losses which are recognized in the statement of income and also to changes in the amount of Brazilian reais necessary to pay such U.S. dollar denominated debt. Changes in interest rates on their fixed rate debt expose Gerdau and Gerdau Açominas to changes in fair value on its debt. In order to manage such risks, Gerdau and Gerdau Açominas used to enter into derivative instruments, primarily cross-currency interest rate swap contracts, but also interest rate swaps. Under the swap contracts Gerdau and Gerdau Açominas have the right to receive on maturity United States dollars plus accrued interest at a fixed rate and have the obligation to pay Brazilian reais at a variable rate based on the CDI rate.

Although such instruments mitigate the foreign exchange and interest rate risks, they do not necessarily eliminate them. The Company generally does not hold derivative instruments for trading purposes.

F-32

All swaps have been recorded at fair value and realized and unrealized losses are presented in the consolidated statement of income under “Gain (losses) on derivatives, net”.

No cross-currency interest rate swaps are outstanding as of September 30, 2006. The notional amount of such cross-currency interest rate swaps amounted $22,116 as of September 30, 2005 and $7,902 as of December 31, 2005, with remaining maturity dates between December 2005 and March 2006 as of September 30, 2005 and between January 2006 and March 2006 as of December 31, 2005. Interest rate payable was between 85.55% to 92.8% of CDI as of September 30, 2005 and between 85.55% and 92.8% of CDI as of December 31, 2005. No unrealized losses were accounted for as of September 30, 2006, but $23 was recorded as an unrealized gain and $10,344 as unrealized losses as of  September 30, 2005, and $6,786 were recorded as a loss as of December 31, 2005.

Gerdau Açominas also entered into interest rate swaps where it receives a fixed interest rate in U.S. dollars and pays a variable interest rate based on LIBOR. The agreements have a notional value of $323,125 and expiration date between November 2008 and November 2011.  The aggregate fair value of this interest rate swap, which represents the amount that would be paid if the agreements were terminated at September 30,2006, is a gain of approximately $3,700 (gain of $1,294 at September 30, 2005 and gain of $2,233 at December 31, 2005).

Gerdau Açominas also entered on a reverse swap where it receives a variable amount of interest based on JIBOR in japanese yens, and pays a fixed interest rate in US dollars, with a notional amount of $267,000. This swap has a final maturity date on September 14, 2016. The aggregate fair value of this swap, which represents the amount that would be paid if the agreements were terminated at September 30, 2006 is a loss of $4,073 (no unrealized loss as of September 30, 2005 and as of December 31, 2005 as the reverse swap was entered into after such dates).

Operations in South America

The Company has granted options to the minority shareholders of Sipar Aceros S.A. as part of the purchase agreements of that company by which those shareholders may sell their shares in Sipar Aceros S.A. and settlement can be made (at the option of the Company or of the shareholders depending on the agreement) either in cash or in shares of Gerdau . Such options are accounted for at its estimated fair value, in the amount of $1,592 as of September 30, 2006, under Other long term liabilities ($5,818 as of December 31, 2005). The Company has a commitment to acquire an additional interest in Diaco which can be settled at the option of the counterparty either in cash or in shares of Gerdau; such commitment is, accounted for at its estimated fair value, in the amount of $49,571, recorded under Other long term assets ($7,529 as of December 31, 2005).

Gerdau Ameristeel Corporation

In order to reduce its exposure to changes in the fair value of its Senior Notes, Gerdau Ameristeel entered into interest rate swaps subsequent to the refinancing of its debt.  The agreements have a notional value of $200,000 and expiration dates of July 15, 2011. Gerdau Ameristeel receives a fixed interest rate and pays a variable interest rate based on LIBOR. The aggregate mark-to-market (fair value) of the interest rate agreements, which represents the amount that would be paid if the agreements were terminated at September 30, 2006 was approximately a loss $2,040  (losses of $1,772 as of September 30, 2005 and $1,170 at December 31, 2005).
