2 INDEPENDENT AUDITORS' REPORT The Benefits Committee Quanex Corporation Houston, Texas Re: Quanex Corporation Hourly Bargaining Unit Employees Savings Plan We have audited the accompanying statements of net assets available for benefits of the Quanex Corporation Hourly Bargaining Unit Employees Savings Plan ("the Plan") as of December 31, 1999 and 1998, and the related statements of changes in net assets available for benefits for the years then ended. These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, such financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 1999 and 1998, and the changes in net assets available for benefits for the years then ended in conformity with accounting principles generally accepted in the United States of America. Our audits were conducted for the purpose of forming an opinion on the basic financial statements taken as a whole. The accompanying supplemental schedule of investments as of December 31, 1999 is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. The supplemental schedule is the responsibility of the Plan's management. This supplemental schedule has been subjected to the auditing procedures applied in our audits of the basic financial statements and, in our opinion, are fairly stated in all material respects when considered in relation to the basic financial statements taken as a whole. /s/ DELOITTE & TOUCHE, LLP - -------------------------- DELOITTE & TOUCHE, LLP June 2, 2000

5 QUANEX CORPORATION HOURLY BARGAINING UNIT EMPLOYEES SAVINGS PLAN NOTES TO FINANCIAL STATEMENTS YEARS ENDED DECEMBER 31, 1999 AND 1998 A. DESCRIPTION OF THE PLAN The following description of the Quanex Corporation Hourly Bargaining Unit Employees Savings Plan (the "Plan") provides only general information. Participants should refer to the Plan document for more complete information. (1) General. The Plan became effective January 1, 1989 and is sponsored by Quanex Corporation (the "Company"). The Plan is a defined contribution Plan, which is subject to the Employee Retirement Income Security Act of 1974 ("ERISA"). The Plan is a voluntary savings plan in which union hourly employees of the MACSTEEL divisions of the Company are eligible to participate after completing three months of active service. Fidelity Management Trust Company ("Fidelity" or the "Trustee") holds the assets of the Plan in trust. The Benefits Committee (the "Committee"), appointed by the Company's Board of Directors, serves as the Plan administrator. (2) Contributions. Participants may elect to contribute up to 15 percent of their before-tax or after-tax compensation as defined by the Plan agreement. (3) Participant Accounts. Each participant's account is credited with the participant's contribution and an allocation of investment income, which is based on individual participant account balances as of the end of the period in which the income is earned. (4) Vesting. Participants are immediately vested in their contributions and the related earnings. (5) Payment of Benefits. Upon termination of service, the participant may elect to receive a lump sum distribution equal to the total amount of vested benefits in his or her account. Terminated participants with an account balance of less than $5,000 will automatically receive a lump sum distribution. B. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (1) Accounting Basis. The financial statements of the Plan are prepared on the accrual basis of accounting in accordance with generally accepted accounting principles. (2) Investment Valuation. The Plan recognizes net appreciation or depreciation in the fair value of its investments. Investments are reflected at fair value in the financial statements. Fair value of mutual fund assets is determined using a quoted net asset value. Fair value for Quanex Corporation unitized common stock, which is listed on the New York Stock Exchange, is determined using the last recorded sales price. The recorded value of the common/commingled trust is at face value, which is fair value. (3) Use of Estimates. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein and disclosure of contingent assets and liabilities. Actual results could differ from these estimates.

6 (4) Administrative Expenses. The Company pays all administrative expenses, except redemption fees imposed on certain Fidelity funds. (5) Payment of Benefits. Benefit payments are recorded when paid. C. INVESTMENTS The following presents investments that represent 5 percent or more of the Plan's net assets.

RELATED PARTY TRANSACTIONS Certain Plan investments are shares of mutual funds managed by Fidelity. Fidelity is the trustee as defined by the Plan and, therefore, these transactions qualify as party-in-interest transactions. In addition, the Plan invests in shares of Quanex Corporation unitized common stock. Quanex Corporation is the Plan sponsor as defined by the Plan and, therefore, these transactions also qualify as party-in-interest transactions. As of December 31, 1999 and 1998, the value of Quanex Corporation common stock held by the Plan was $159,039 and $199,494, respectively. E. PLAN TERMINATION Although it has not expressed any intention to do so, the Company has the right under the Plan to terminate the Plan at any time subject to the provisions set forth in ERISA. In the event of Plan termination, the assets held by the Trustee under the Plan will be valued and fully vested, and each participant will be entitled to distributions respecting his or her account. F. FEDERAL INCOME TAX STATUS The Plan is subject to specific rules and regulations related to employee benefit plans under the Department of Labor and the Internal Revenue Service (the "IRS"). The Plan has received a favorable letter of tax determination dated April 25, 1997. As such, the Plan is a qualified trust under Sections 401(a) and 401(k) of the Internal Revenue Code (the "Code") and, as a result, is exempt from federal income tax under Section 501(a) of the Code. The Company believes the Plan is currently designed and being operated in compliance with the applicable requirements of the Code. The Company believes the Plan was qualified and the related trust was tax-exempt as of the federal statement dates.

7 G. TRANSFER OF ASSETS On December 3, 1997, Michigan Seamless Tube Company, the Gulf States Tube and the Tube Group Office divisions of Quanex Corporation (the "Tube Group") were sold to Vision Metals, Inc. In plan years 1999 and 1998, assets of the Plan attributable to the Tube Group employees in the amount of $7,703 and $4,700,123, respectively, were transferred to the new qualified savings plan established by Vision Metals, Inc. H. SUBSEQUENT EVENTS Effective February 1, 2000 the employees at MACSTEEL's Fort Smith, Arkansas facility who were covered by a collective bargaining agreement became participants in the Plan. Their account balances in the Quanex Employee Savings Plan will be transferred to the Plan on June 30, 2000.
