INDEPENDENT AUDITORS' REPORT


To the Participants in
A. M. Castle & Co. Employees' Profit Sharing Plan:

We have audited the accompanying statement of net assets available for benefits
of A. M. Castle & Co. Employees' Profit Sharing Plan (the "Plan") as of December
31, 2002, and the related statement of changes in net assets available for
benefits for the year 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 audit. Other auditors, who
have ceased operations, were engaged to audit the financial statements of the
Plan for the year ended December 31, 2001 and their report, dated May 31, 2002,
expressed an unqualified opinion on those statements.

We conducted our audit 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 audit provides a
reasonable basis for our opinion.

In our opinion, the 2002 financial statements referred to above present fairly,
in all material respects, the net assets available for benefits of A. M. Castle
& Co. Employees' Profit Sharing Plan as of December 31, 2002, and the changes in
net assets available for benefits for the year then ended, in conformity with
accounting principles generally accepted in the United States of America.

Our audit was performed for the purpose of forming an opinion on the basic 2002
financial statements taken as a whole. The accompanying supplemental schedule
listed in the table of contents 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. This schedule is the responsibility of the Plan's
management. Such schedule has been subjected to the auditing procedures applied
in the audit of the basic 2002 financial statements and, in our opinion, is
fairly stated in all material respects in relation to the basic 2002 financial
statements taken as a whole.

A. M. CASTLE & CO. EMPLOYEES' PROFIT SHARING PLAN

NOTES TO FINANCIAL STATEMENTS AS OF DECEMBER 31, 2002 AND 2001, AND
FOR THE YEAR ENDED DECEMBER 31, 2002
--------------------------------------------------------------------------------


1. DESCRIPTION OF THE PLAN

     The following description of A. M. Castle & Co. Employee's Profit Sharing
     Plan (the "Plan") is provided for general information purposes only.
     Participants should refer to the Plan document for more complete
     information

     General--The Plan was established on January 1, 1957. The Plan was amended
     and restated from time to time to provide a means for eligible (salaried
     and nonsalaried) employees to participate in the earnings of A. M. Castle &
     Co. in order to build a supplemental retirement fund and to provide
     additional disability and death benefits. Participants should refer to the
     Plan document for more complete information.

     The Plan is a defined contribution profit-sharing and 401(k) plan available
     to salaried and other eligible employees of A. M. Castle & Co. and certain
     of its subsidiaries (collectively referred to as the "Company"). Employees
     of the Company are eligible to become participants in the Plan upon
     completion of 30 days of service for the 401(k) portion of the Plan and 1
     year of service for the profit-sharing portion of the Plan. The Plan is
     subject to the provisions of the Employee Retirement Income Security Act of
     1974 ("ERISA").

     Trustee--ABN AMRO is the trustee of the Plan. The Plan's trust fund is
     administered under the terms of certain trust agreements between the
     Company and ABN AMRO. The trust agreements provide, among other things,
     that the trustee shall account for all investments, receipts and
     disbursements and other transactions and shall provide annually a report
     setting forth such transactions and the status of the fund at the close of
     the period.

     Transfers from Other Plans--Effective January 2, 2002, all the assets and
     liabilities of the plan participants of the Oliver Steel Plate Corporation
     Employees' Profit Sharing Plan were transferred into and merged with A. M.
     Castle & Co. Employees' Profit Sharing Plan.

     Participant Accounts--Each participant may contribute up to 17% of the
     participant's pretax compensation if an employee of A. M. Castle & Co. and
     16% if an employee of Oliver Steel Plate Corporation, as defined by the
     Plan, subject to Internal Revenue Code ("IRC") limitations. Contributions
     up to 5% of the participants after-tax compensation, as defined by the
     Plan, can also be made, but no more than 17% if an employee of A. M. Castle
     & Co. and 16% if an employee of Oliver Steel Plate Corporation. Similar to
     pretax contributions, the earnings on these contributions accumulate on a
     tax-deferred basis. Participants direct the investment of their participant
     contributions among various investment options offered by the Plan,
     including the common stock of the Company.

     Employer Contributions--The employer's matching contribution is 25% of each
     dollar the employee contributes to the Plan up to the first 6% of the
     participant's pretax compensation. The employer's matching contribution for
     employees of Oliver Steel Plate Corporation is 50% of each dollar the
     employee contributes to the plan up to the first 6% of the participant's
     pretax compensation. Additionally, the Company may also make profit-sharing
     contributions. The employer's profit-sharing contribution to the Plan is


                                   -4-




     determined at Company management's discretion as defined by the Plan. There
     was no Company profit-sharing contribution for the year ended December 31,
     2002. Company contributions are invested directly into A. M. Castle & Co.
     common stock.

     Company profit-sharing contributions are allocated to participants'
     accounts in the ratio of their yearly covered compensation to the total of
     all participants' yearly covered compensation.

     Vesting--Participant contributions and earnings thereon are at all times
     100% vested. For employer matching and profit-sharing contributions to the
     Plan and any earnings thereon, participants, after completing one calendar
     year of service, will be one-third vested. Upon completion of three years
     of service, participants will become two-thirds vested in the matching
     401(k) portion of the Plan until completion of five years of service, at
     which time they will become fully vested in both the 401(k) and
     profit-sharing portions of the Plan. In addition, the Plan contains
     provisions under which the entire amount credited to a participant's
     account is distributable upon a participant's disability or death.

     Forfeitures--Employer contributions may be reduced by the amount of
     employee forfeitures. The amount of forfeitures, which reduced employer
     contributions for the year ended December 31, 2002 was $41,319. At December
     31, 2002, there were unallocated forfeitures of $92,138.

     Allocations of Income--Earnings of the Plan, as defined, are allocated to
     participants' accounts based on the proportion of each participant's
     account balance within each fund to the total account balance.

     Participant Loans--Participants may borrow a minimum of $1,000 and a
     maximum or the lesser of $50,000 or 50% of their vested account balances
     from the amount in their accounts for a specified time period, as defined
     in the Plan document. Interest is charged on outstanding loans at two
     percentage points above the prime rate in effect at the time of the loan.
     Loan rates are established at the beginning of each quarter. Loans are
     secured by the balance in the participant's account. Upon termination of
     employment, participant loans (if in default) are first deducted from
     participant equity, with the remaining equity balance distributed to the
     participant.

     Payment of Benefits--Distributions from the Plan will not be made until a
     participant retires, dies or otherwise terminates employment with the
     Company. Distributions are made in cash in a lump sum or an installment
     basis or can be rolled over to another plan or an individual's IRA account.
     Distributions are recorded when paid.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Accounting--The accompanying financial statements have been
     prepared in accordance with accounting principles generally accepted in the
     United States of America.

     Use of Estimates-- The preparation of financial statements in conformity
     with accounting principles generally accepted in the United States of
     America requires the use of estimates and assumptions that affect the
     reported amounts of net assets available for benefits and changes therein.
     Actual results could differ from those estimates. The Plan utilizes various
     investment instruments, including mutual funds, and common stock.
     Investment securities, in general, are exposed to various risks, such as
     interest rate, credit and overall market volatility. Due to the level of
     risk associated with certain investment securities, it is reasonably
     possible that changes in the values of investment securities will occur in
     the near term and that such changes could materially affect the amounts
     reported in the financial statements.

                                      -5-




     Investment Valuation and Income Recognition--Net appreciation
     (depreciation) in fair value of investments is calculated as the difference
     between market value at January 1 or date of purchase, if subsequent to
     January 1, and market value at year-end.

     Investments are stated at fair value, based on quoted market prices as of
     the last day of the year. Interest and dividends earned on investments, but
     not yet received, are included in the statements of net assets available
     for benefits. Participant loans are valued at the outstanding loan
     balances.

     Contributions--Participant contributions are recorded in the period in
     which the Company makes payroll deductions from the Plan's participants.

     Benefit Payments--Benefit payments to participants are recorded upon
     distribution. There are no amounts allocated to accounts of persons who
     have elected to withdraw from the Plan but have not yet been paid at
     December 31, 2002 and 2001.

     Administrative Expenses--Administrative and trustee expenses are paid by
     the Company, with the exception of loan issuance and maintainance fees,
     which are paid by the Plan.

5. FEDERAL INCOME TAX STATUS

     The Internal Revenue Service has determined and informed the Company by a
     letter dated August 2, 2002, that the Plan and related trust were designed
     in accordance with applicable sections of the Internal Revenue Code. The
     Plan has been amended since receiving the determination letter; however,
     the Plan management believes that the Plan is designed and is currently
     being operated in compliance with the applicable requirements of the
     Internal Revenue Code. Therefore, no provision for income taxes has been
     included in the Plan's financial statements.

6. PLAN TERMINATION

     Although the Company has not expressed any intent to do so, it reserves the
     right under the Plan to discontinue its contributions at any time and
     terminate the Plan subject to the provisions set forth in ERISA. In the
     event of termination of the Plan, no part of the trust fund shall revert to
     the Company. The trust fund shall be distributed to the participants and
     beneficiaries as of the date of termination in the ratio that the credit
     balances in their accounts bear to the total credit balance of the accounts
     of all participants.

                                      -7-




7. RELATED-PARTY TRANSACTIONS

     ABN AMRO acts as trustee for the Plan and manages its investments.
     Additionally, certain Plan investments are shares of a mutual fund managed
     by the trustee, ABN AMRO. Transactions in such investments, including loans
     made to plan participants, qualify as party-in-interest transactions, which
     are exempt from the prohibited transaction rules.

     As described in Note 1, the Plan invests in the common stock of the plan
     sponsor, A. M. Castle & Co.
