ABOUT THIS PROSPECTUS
 
This prospectus is part of a registration statement that we filed with the Securities and Exchange Commission, or the SEC, utilizing a “shelf” registration process. Under this shelf process, we, together with the selling stockholders, may sell the securities described in this prospectus in one or more offerings. This prospectus provides you with a general description of the securities we and the selling stockholders may offer. Each time we and the selling stockholders sell securities, we and the selling stockholders will provide a prospectus supplement that will contain specific information about the terms of that offering. The prospectus supplement may also add, update or change information contained in this prospectus. You should read both this prospectus and any prospectus supplement together with additional information described under the heading “Where You Can Find More Information.” You should rely only on the information contained in or incorporated by reference in this prospectus and any prospectus supplement. Neither we nor the selling stockholders have authorized anyone to provide you with information other than the information contained or incorporated by reference in this prospectus or any prospectus supplement. Neither we nor the selling stockholders are making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. The information contained in this prospectus speaks only as of the date of this prospectus and the information in the documents incorporated or deemed to be incorporated by reference in this prospectus speaks only as of the respective dates those documents were filed with the SEC. Unless otherwise indicated or the context otherwise requires, in this prospectus: “A. M. Castle”, the “Company,” “we,” “us” and “our” refer to A. M. Castle & Co. and its subsidiaries.
 
A. M. CASTLE & CO.
 
We believe that we are a leading distributor and provider of processed specialty metals and plastics to a wide range of commercial customers serving principally the North American market, but with a significantly growing global presence. Our business is organized into two reportable segments, Metals and Plastics. Our Metals segment is primarily focused on supplying, processing and distributing engineered and specialized grades of metals including specialty steel, titanium, aluminum and high performance nickel alloys in a variety of forms such as plates, sheet, round bar, hexagon, square and flat bars, tubing and coil. Our Metals segment performs processing services to meet customer requirements, including cutting, grinding, shearing, heat treating, burning and annealing. Our Plastics segment stocks and distributes a wide variety of plastics in forms that include plate, rod, tube, clear sheet, tape, gaskets and fittings. Processing activities within our Plastics segment are based on customer specification and include cut to length, cut to shape, bending and forming.
 
We were originally incorporated in Illinois in 1890 and reincorporated in Delaware in 1966. In 2001, we reincorporated in Maryland by merging into a subsidiary incorporated in Maryland. Our corporate and executive offices are located at 3400 N. Wolf Road, Franklin Park, Illinois 60131, and our telephone number at that address is (847) 455-7111. We maintain a website at www.amcastle.com. The information contained in our website is not a part of, and is not incorporated by reference into, this prospectus.
 
RISK FACTORS
 
Before you invest in our common stock, in addition to the other information, documents or reports incorporated by reference in this prospectus and in any prospectus supplement, you should carefully consider the risk factors set forth in the section entitled “Risk Factors” in any prospectus supplement as well as in “Part I, Item 1A. Risk Factors,” in our most recent annual report on Form 10-K, and in “Part II, Item 1A. Risk Factors,” in our quarterly reports on Form 10-Q filed subsequent to such Form 10-K, which are incorporated by reference into this prospectus and any prospectus supplement in their entirety, as the same may be updated from time to time by our future filings under the Exchange Act. Each of the risks described in these sections and documents could materially and adversely affect our business, financial condition, results of operations and prospects, and could result in a loss of your investment.

USE OF PROCEEDS
 
Unless otherwise indicated in a prospectus supplement, the net proceeds from the sale of the securities by A. M. Castle will be used for retirement of debt and general corporate purposes. We will not receive any of the proceeds from the sale of shares by the selling stockholders.
 
DIVIDEND POLICY
 
We paid no dividends in 2005. We have declared and paid a dividend of $0.06 per share on our common stock in each of the quarters of 2006 and the first quarter of 2007. Our current dividend policy anticipates the payment of quarterly dividends in the future. The declaration and payment of dividends to holders of common stock will be in the discretion of our Board of Directors, will be subject to contractual restrictions contained in our then-existing credit facilities and will be dependent upon our future earnings, cash flows, financial condition and capital requirements, general business conditions, legal, tax, regulatory and other factors our Board of Directors deems relevant. In addition, under the terms of our charter, so long as any shares of Series A Cumulative Convertible Preferred Stock, which we refer to as our Series A Preferred Stock, remain outstanding, we may not pay or declare dividends on our common stock unless we are current on our Series A Preferred Stock dividends, in which case we may pay cash dividends with respect to our common stock in an amount not to exceed $.50 per share per year. Upon the conversion of all of the Series A Preferred Stock, the existing limitation to keep dividends no greater than $.50 per share of common stock will no longer exist. Under the terms of the Series A Preferred Stock, we have a right to convert all outstanding Series A Preferred Stock if our closing common stock price on any date after November 22, 2007 exceeds $13.38 per share on the stock exchange on which our common stock is traded.
 
SELLING STOCKHOLDERS
 
We have included 2,000,000 shares owned by the selling stockholders in the registration statement of which this prospectus is a part. We have agreed to pay the fees and expenses of the registration of the shares of the selling stockholders.

(1) The shares being sold by the selling stockholders are held of record by W.B. & Co. W. B. & Co. is a nominee partnership. Simpson Estates, Inc. and Patrick J. Herbert, III serve as general partners of W.B. & Co. Patrick J. Herbert, III is President of Simpson Estates, Inc. The principal business address of these entities is c/o Simpson Estates, Inc., 30 North LaSalle St., Suite 1232, Chicago, Illinois 60602-2504.
 
(2) Includes 1,793,722 shares that are issuable upon conversion of our Series A Preferred Stock.
 
(3) Assumes the issuance of 3,000,000 shares which may be offered by the Company pursuant to this prospectus.
 
(4) Patrick J. Herbert, III is the trustee.
 
(5) United States Trust Company, N.A. is the trustee.
 
In November 2002, we sold the Series A Preferred Stock in a private placement to a number of current shareholders mainly comprised of W.B. & Co., an Illinois partnership of which Patrick J. Herbert, III, a director of the Company, is a general partner, for an aggregate purchase price of $12,000,000. Each share of the Series A Preferred Stock has an initial conversion price of $6.69 per share of common stock, participates on an as-converted basis with any dividends declared and paid on the common stock and is entitled to receive a preferred cumulative dividend payable at an annual rate of 8% of the sum of $1,000 plus any accumulated and unpaid dividends, reduced by the amount of dividends paid on the common stock into which the share of Series A Preferred Stock is convertible. To the extent dividends paid on the common stock would yield a return in excess of the dividend on the Series A Preferred Stock, then subsequent dividends payable in respect of the Series A Preferred Stock will be reduced by the amount of such excess. We agreed to register the common stock issuable upon conversion of the Series A Preferred Stock under the Securities Act of 1933 and have it listed on the stock exchange on which our common stock is traded. The common stock ownership reported in the above table is calculated and shown as if the shares of Series A Preferred Stock were converted into common stock.

They use words such as “aim,” “anticipate,” “believe,” “could,” “estimate,” “expect,” “intend,” “may,” “plan,” “project,” “should,” “will be,” “will continue,” “will likely result,” “would” and other words and terms of similar meaning in conjunction with a discussion of future operating or financial performance or future events. You should read statements that contain these words carefully, because they discuss our future expectations, contain projections of our future results of operations or of our financial position or state other “forward-looking” information.
 
The factors listed under “Risk Factors,” as well as any cautionary language in this prospectus and any accompanying prospectus supplements, provide examples of risks, uncertainties and events that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements. Although we believe that our expectations are based on reasonable assumptions, actual results may differ materially from those in the forward-looking statements as a result of various factors, including, but not limited to, those described above under the heading “Risk Factors” and elsewhere in this prospectus and any accompanying prospectus supplements. Before you invest in our common stock, you should read this prospectus and any accompanying prospectus supplements completely and with the understanding that our actual future results may be materially different from what we expect.
 
Forward-looking statements speak only as of the date of this prospectus and any accompanying prospectus supplements as applicable. Except as required under federal securities laws and the rules and regulations of the SEC, we do not have any intention, and do not undertake, to update any forward-looking statements to reflect events or circumstances arising after the date of this prospectus or any accompanying prospectus supplements as applicable, whether as a result of new information, future events or otherwise. As a result of these risks and uncertainties, readers are cautioned not to place undue reliance on the forward-looking statements included in this prospectus or that may be made elsewhere from time to time by, or on behalf of, us.

Item 15.   Indemnification of Directors and Officers
 
Section 2-405.2 of the Maryland General Corporation Law permits a Maryland corporation to include in its charter a provision limiting the liability of its directors and officers to the corporation and its stockholders for money damages except for liability resulting from (a) actual receipt of an improper benefit or profit in money, property or services for the amount of the benefit or profit in money, property or services actually received or (b) active and deliberate dishonesty established by a final judgment which is material to the cause of action. Our charter contains such a provision which eliminates directors’ and officers’ liability to the maximum extent permitted by Maryland law.
 
Section 2-418 of Maryland General Corporation Law requires a corporation (unless its charter provides otherwise, which our charter does not) to indemnify a director or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he is made a party by reason of his service in that capacity. Maryland law permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made a party by reason of their service in those or other capacities unless it is established that (a) the act or omission of the director or officer was material to the matter giving rise to the proceeding and (1) was committed in bad faith or (2) was the result of active and deliberate dishonesty, (b) the director or officer actually received an improper personal benefit in money, property or services or (c) in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful. However, under Maryland law, a Maryland corporation may not indemnify for an adverse judgment in a suit by or in the right of the corporation or for a judgment of liability on the basis that personal benefit was improperly received, unless in either case a court orders indemnification and then only for expenses. In addition, Maryland law permits a corporation to advance reasonable expenses to a director or officer upon the corporation’s receipt of (x) a written affirmation by the director or officer of his good faith belief that he has met the standard of conduct necessary for indemnification by the corporation and (y) a written undertaking by him or on his behalf to repay the amount paid or reimbursed by the corporation if it is ultimately determined that the standard of conduct was not met.
 
Our by-laws require us to indemnify to the fullest extent permitted by Maryland law in effect from time to time any person who is a present or former director, officer or employee of the Company and who is made a party to any proceeding (including any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative) by reason of such person’s service in such capacity or as a director, officer, partner, trustee or employee of any other corporation, partnership, joint venture, trust, employee benefit plan or other enterprise which he served as such at the request of the Company against all


II-1


Table of Contents

judgments, penalties, fines, settlements and reasonable expenses actually incurred by him in connection with such proceeding, unless it is established that (a) the act or omission of such person was material to the matter giving rise to the proceeding and was committed in bad faith or was the result of active and deliberate dishonesty or (b) such person actually received an improper personal benefit in money, property or services or (c) in the case of any criminal proceeding, such person had reasonable cause to believe that the act or omission was unlawful. We may, with the approval of our Board of Directors, provide such indemnification to a person who served a predecessor of the Company in any of the capacities described above and to any agent of the Company or a predecessor of the Company.
 
We maintain a directors’ and officers’ liability insurance policy. The policy insures our directors and officers against unindemnified losses ensuing from certain wrongful acts in their capacities as directors and officers and reimburses us for those losses for which we have lawfully indemnified the directors and officers. This policy contains various exclusions, none of which apply to this offering.

Item 17.   Undertakings
 
(a) The undersigned Registrant hereby undertakes:
 
(1) To file, during any period in which offers or sales are being made of securities registered hereby, a post-effective amendment to this registration statement:
 
(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;
 
(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the


II-2


Table of Contents

form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;
 
(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;
 
provided, however, that paragraphs (i), (ii) and (iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Securities and Exchange Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.
 
(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.
 
(4) That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:
 
(A) Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and
 
(B) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.
 
(5) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities:
 
The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:
 
(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;


II-3


Table of Contents

 
(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;
 
(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and
 
(iv) Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.
 
(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
 
(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrants pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
