SUMMARY

        The following summary is qualified in its entirety by, and should be read in conjunction with, the more detailed information and financial statements (including the notes thereto) appearing elsewhere or incorporated by reference in this prospectus supplement and the accompanying prospectus. Because this is a summary it may not contain all the information that may be important to you. You should read the entire prospectus supplement and the accompanying prospectus, as well as any related free writing prospectus and the information incorporated by reference, before making an investment decision. Some of the statements in this "Summary" are forward-looking statements. Please see "Forward-Looking Statements" for more information regarding these statements.

Our Business

        We are a global Tier 1 supplier to the automotive industry. We design, engineer and manufacture driveline and metal forming products that are making the next generation of vehicles smarter, lighter, safer and more efficient. We employ over 20,000 associates, operating at nearly 80 facilities in 17 countries, to support our customers on global and regional platforms with a focus on quality, operational excellence and technology leadership.

        We are a primary supplier of driveline components to General Motors Company (GM) for its full-size rear-wheel drive (RWD) light trucks, sport utility vehicles (SUVs), and crossover vehicles manufactured in North America, supplying a significant portion of GM's rear axle and four-wheel drive and all-wheel drive (4WD/AWD) axle requirements for these vehicle platforms. We also supply GM with various products from our Metal Forming segment. Sales to GM were approximately 41% of our consolidated net sales in the first three months of 2020, 39% in the first three months of 2019, and 37% for the full year 2019.

        We also supply driveline system products to FCA US LLC (FCA) for heavy-duty Ram full-size pickup trucks and its derivatives, the AWD Jeep Cherokee, and a passenger car driveshaft program. In addition, we sell various products to FCA from our Metal Forming segment. Sales to FCA were approximately 16% of our consolidated net sales in the first three months of 2020, 12% in the first three months of 2019, and 17% for the full year 2019.

        We are also a supplier to Ford Motor Company (Ford) for driveline system products on certain vehicle programs, and we sell various products to Ford from our Metal Forming segment. Sales to Ford were approximately 12% of our consolidated net sales in the first three months of 2020, and approximately 9% for both the first three months and full year of 2019.

Recent Developments

        On May 8, 2020, Holdings filed its Quarterly Report for the quarter ended March 31, 2020, which included the following disclosure in "Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations" under the heading "Impact of Novel Coronavirus (COVID-19)" in the "Company Overview" Section:

        In March of 2020, COVID-19 was designated by the World Health Organization as a pandemic illness and began to significantly disrupt global automotive production. In an effort to mitigate the spread of COVID-19, many governmental and public health agencies in locations in which we operate implemented shelter-in-place orders or similar measures. Substantially all of our customers ceased or significantly reduced production, and the decline in production volumes has continued into the second quarter of 2020. As a result, substantially all of our manufacturing facilities have either temporarily suspended production or experienced significant reductions in volumes during this period. By the end of the first quarter of 2020, our manufacturing locations in Asia were beginning to stabilize and return to more normalized levels of production.

S-1


Table of Contents

        In addition, the Quarterly Report for the quarter ended March 31, 2020, included the following disclosure in the "Liquidity and Capital Resources" Section under the heading "COVID-19 Considerations Related to Liquidity and Capital Resources":

        At March 31, 2020, we had over $1.4 billion of liquidity consisting of approximately $683 million of cash and cash equivalents, approximately $691 million of available borrowings under our Revolving Credit Facility and approximately $86 million of available borrowings under foreign credit facilities. Further, we have no significant debt maturities before October 2022. Based on our liquidity profile and no significant debt maturities in 2020, as well as the measures that we are taking to conserve cash, we believe that we will have sufficient funds available to continue operating with no significant changes to our capital structure until such time as production returns to more normalized levels.

        For additional information, see Holdings' Quarterly Report for the quarter ended March 31, 2020 filed with the SEC on May 8, 2020, which is incorporated by reference herein.

        As an update, during the month of May 2020, AAM restarted its operations in North America and Europe and is currently in the process of ramping up production, along with our customers and supply base. In addition, AAM expects to have at least $1.2 billion of liquidity at June 30, 2020.

(a)
In 2019, we recorded a charge of $225 million to reduce the carrying value of our U.S. Casting operations to fair value less cost to sell upon reclassification of the assets and liabilities to held-for-sale, and a goodwill impairment charge of $440 million associated with the annual goodwill impairment test for our Metal Forming segment.

(b)
In 2019, we completed the sale of our U.S. Casting operations for $245 million, consisting of $185 million in cash, of which we received net proceeds of $141.2 million subsequent to certain customary closing adjustments, and a $60 million deferred payment obligation. As a result of the sale, we recorded a loss of $21.3 million.

(c)
In 2019, we recognized a gain on bargain purchase of $10.8 million associated with the acquisition of certain operations of Mitec Automotive AG.

(d)
In 2019, we offered a voluntary one-time lump sum payment option to certain eligible terminated vested participants in our U.S. pension plans that, if accepted, would settle our pension obligations to them. As a result of this settlement, we remeasured the assets and liabilities of our U.S. pension plans, which resulted in a non-cash charge of approximately $7.7 million, net of tax, related to the accelerated recognition of certain deferred losses.

(e)
We recorded a goodwill impairment charge in 2018 associated with the annual goodwill impairment test for our Casting and former Powertrain segments.

(f)
In 2018, we completed the sale of the aftermarket business associated with our former Powertrain segment for approximately $50 million, of which we received net proceeds of $47.1 million. As a result of the sale, we recorded a $15.5 million gain.

(g)
In 2018, we reached a settlement agreement related to a capital lease obligation that we had recognized as a result of the acquisition of MPG. This settlement resulted in a gain of $15.6 million, including accrued interest.

(a)
We define EBITDA to be earnings before interest expense, income taxes, depreciation and amortization. Adjusted EBITDA is defined as EBITDA excluding the impact of restructuring and acquisition-related costs, debt refinancing and redemption costs, gain (loss) on the sale of a business, impairment charges, pension settlements and non-recurring items. We believe that EBITDA and Adjusted EBITDA are meaningful measures of performance as they are commonly utilized by management and investors to analyze operating performance and entity valuation. Our management, the investment community and the banking institutions routinely use EBITDA and Adjusted EBITDA, together with other measures, to measure our operating performance relative to other Tier 1 automotive suppliers. EBITDA and Adjusted EBITDA should not be construed as income from operations, net income or cash flow from operating activities as determined under GAAP. Other companies may calculate EBITDA and Adjusted EBITDA differently.

(b)
In 2019, includes a net gain of $10.8 million of recognized gain on bargain purchase associated with the acquisition of certain operations of Mitec Automotive AG and $2.4 million of other non-recurring items. In 2018, includes a net gain of $15.6 million in connection with the settlement of capital lease obligations. In 2017, includes $24.9 million for an acquisition-related fair value adjustment to inventory and a net gain of $3.7 million related to a change of our method of accounting for indirect inventory.

RISK FACTORS

        You should carefully consider the specific risk factors set forth below as well as the other information contained or incorporated by reference in this prospectus supplement and the accompanying prospectus before deciding to invest in the notes. See Item 1A "Risk Factors" in Holdings' Annual Report on Form 10-K for the year ended December 31, 2019 and Quarterly Report on Form 10-Q for the three months ended March 31, 2020. Some factors in this section are "forward-looking statements." For a discussion of those statements and of other factors for investors to consider, see "Forward-Looking Statements."

Our business and financial condition have been, and may continue to be, adversely affected by the impact of COVID-19.

        Our business is subject to risks associated with public health issues, including pandemics such as COVID-19. COVID-19 has disrupted global economic markets and has led to significant reductions in global automotive production volumes. As a result of COVID-19, governmental and public health officials in substantially all of the locations in which we operate have mandated certain precautions to mitigate the spread of the disease, including shelter-in-place orders or similar measures. As such, we have temporarily suspended production, or experienced a significant reduction in production volumes, in substantially all of our manufacturing facilities.

        Our results of operations and financial condition have been, and may continue to be, adversely impacted by the actions taken to contain the impact of COVID-19, and the ultimate extent of such impact will depend on future developments, such as the duration and extent of the pandemic, its impact on: consumers and sales of the vehicles we support, our customers and our and their suppliers, how quickly normal economic conditions and our and our customers' operations can resume, and whether the pandemic leads to recessionary conditions. In addition, government sponsored economic stimulus programs in response to the pandemic may not be available to our customers, our suppliers or us or achieve their economic goals. Our supply chain also may be disrupted due to supplier closures or bankruptcies. Our operations may also be impacted by interruptions due to the direct impact of, or precautionary measures associated with, COVID-19 at our locations or those of our customers or suppliers.

        Further, COVID-19 could exacerbate other risks disclosed in this prospectus supplement and in Item 1A. "Risk Factors" as included in our Annual Report on Form 10-K for the year ended December 31, 2019. These risks include, but are not limited to, dependency on certain customers, dependency on certain global automotive market segments, risks and uncertainties associated with our company's global operations, dependency on certain key manufacturing facilities, cyclicality in the automotive industry, and disruptions in our supply chain and our customers' supply chain.

The notes do not restrict our ability to incur additional unsecured debt, including debt of our subsidiaries, or prohibit us from taking other action that could negatively impact holders of the notes and the notes will be structurally subordinated to the debt and other liabilities of subsidiaries that do not guarantee the notes.

        We are not restricted under the terms of the indenture or the notes from incurring additional indebtedness, including indebtedness of our subsidiaries.

        Not all of our subsidiaries will guarantee the notes. In the event of a bankruptcy, liquidation or reorganization of any of our non-guarantor subsidiaries, including any of our foreign subsidiaries, holders of their indebtedness and their trade creditors will generally be entitled to payment of their claims from the assets of those entities before any assets are made available for distribution to us. As a result, the notes will effectively be subordinated to the prior payment of all of the liabilities of our non-guarantor subsidiaries.

S-8


Table of Contents

        As of March 31, 2020, the non-guarantor Subsidiaries of AAM Inc. and MPG had total assets (net of intercompany receivables) of $2,789.8 million and total liabilities (net of intercompany notes and payables) of $913.5 million (including indebtedness of $102.7 million). In addition, on a consolidated basis, AAM had consolidated indebtedness of $3,733.4 million, net of debt issuance costs of $48.3 million. The terms of the indenture limit our ability to secure additional debt without also securing the notes and to enter into sale and leaseback transactions. However, these limitations are subject to numerous exceptions. See "—The notes are unsecured and effectively subordinated to our existing and future secured indebtedness" and "Description of the Notes—Material Covenants" in the prospectus supplement and the accompanying prospectus. In addition, the notes do not require us to achieve or maintain any minimum financial results relating to our financial position or results of operations. Our ability to recapitalize, incur additional debt, secure existing or future debt or take a number of other actions that are not limited by the terms of the indenture and the notes could have the effect of diminishing our ability to make payments on the notes when due.

The notes are unsecured and effectively subordinated to our existing and future secured indebtedness.

        Our obligations under the notes will not be secured by any of our assets, while our obligations under the Senior Secured Credit Facilities are secured on a first priority basis by all or substantially all of the assets of Holdings, AAM Inc. and each Subsidiary Guarantor, including a pledge of all capital stock of AAM Inc. and the Subsidiary Guarantors and a portion of the capital stock of the first tier foreign subsidiaries of Holdings, AAM Inc. and the Subsidiary Guarantors. Therefore, the lenders under the Senior Secured Credit Facilities and holders of any other secured debt that we or our subsidiaries may incur in the future, will have claims with respect to these assets that have priority over the claims of the holders of the notes.

        In the event that we are declared bankrupt, become insolvent or are liquidated or reorganized, holders of secured obligations will be entitled to be paid to the extent of the value of the assets securing such debt. Thereafter, holders of the notes will participate ratably with all holders of our other senior unsecured indebtedness, based upon the respective amounts owed to each holder or creditor, in our remaining assets, if any. In any of the foregoing events, we cannot assure you that there will be sufficient assets to pay amounts due on the notes. As a result, holders of the notes may receive less, ratably, than holders of our secured indebtedness.

        As of March 31, 2020, we had $1,728.8 million of secured indebtedness outstanding and approximately $691.4 million of secured debt available for additional borrowing under our Senior Secured Credit Facilities. As of June 5, 2020, we had $383.6 million outstanding under our Revolving Credit Facility (including $33.6 million for standby letters of credit issued against the facility) and had $541.4 million of borrowing capacity available under the Revolving Credit Facility. See "Description of Certain Other Indebtedness."

Our significant indebtedness could adversely affect our financial health and prevent us from fulfilling our obligations.

        We have now and will continue to have a significant amount of indebtedness. As of March 31, 2020, our total outstanding indebtedness was approximately $3,733.4 million, net of debt issuance costs of $48.3 million, of which $1,728.8 million was secured, and we had $691.4 million available for additional secured borrowing under our Senior Secured Credit Facilities.

        Our significant indebtedness could have material consequences. For example, it could:

S-9


Table of Contents

        Any of these risks could impact our ability to fund our operations or limit our ability to expand our business, which could have a material adverse effect on our business, financial condition and results of operations.

To service our indebtedness and fund our working capital and capital expenditures, we will require a significant amount of cash. Our ability to generate cash depends on many factors beyond our control.

        Our ability to make payments on our indebtedness will depend upon our future operating performance and our ability to generate cash flow in the future, which are subject to the impact of COVID-19, and general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. We cannot assure you that our business will generate sufficient cash flow from operations, or that future borrowings will be available to us, in an amount sufficient to enable us to pay our indebtedness or to fund our other liquidity needs. If the cash flow from our operating activities is insufficient, we may take actions, such as delaying or reducing capital expenditures, attempting to restructure or refinance our indebtedness prior to maturity, selling assets or operations or seeking additional equity capital. Any or all of these actions may be insufficient to allow us to service our debt obligations. Further, we may be unable to take any of these actions on commercially reasonable terms, if at all.

We may be unable to refinance our outstanding indebtedness, including the notes.

        We may need to refinance all or a portion of our indebtedness before the maturity date of the notes, including indebtedness under the indentures governing our senior notes. To the extent they remain outstanding, our 6.625% senior unsecured notes are due in 2022 (the "6.625% Notes"), our 6.25% senior unsecured notes are due in 2025 (the "6.25% Notes due 2025"), our 6.25% senior unsecured notes are due in 2026 (the "6.25% Notes due 2026") and our 6.50% senior unsecured notes are due in 2027 (the "6.50% Notes"). There can be no assurance that we will be able to obtain sufficient funds to enable us to repay or refinance our debt obligations on commercially reasonable terms or at all.

Covenants in our Credit Agreement, indenture and agreements that we may enter into in the future may limit our ability to operate our business.

        The Senior Secured Credit Facilities contains covenants that restrict our ability to make distributions or other payments to our investors. In addition, these agreements include covenants restricting the ability, among other things, of AAM Inc. to:

S-10


Table of Contents

        These restrictions could limit our ability to make borrowings, obtain debt financing, repurchase stock, refinance or pay principal or interest on our outstanding indebtedness, complete acquisitions for cash or debt or react to changes in our operating environment. Any credit agreement or indenture that we may enter into in the future may have similar restrictions.

        If we default under the Credit Agreement or any of our indentures because of a covenant breach or otherwise, all outstanding amounts thereunder could become immediately due and payable. We cannot assure you that we will be able to obtain a waiver under any credit agreement, indenture or similar instrument in the future should a default occur. We cannot assure you that we would have sufficient funds to repay all of the outstanding amounts under the Credit Agreement, indenture governing our senior secured notes and indentures governing our senior unsecured notes and the notes offered hereby, and any acceleration of amounts due would have a material adverse effect on our liquidity and financial condition.

A significant portion of our assets consists of goodwill and intangible assets.

        As of March 31, 2020, approximately 17% of our assets consisted of goodwill and intangible assets. The value of our assets and, in particular, our intangible assets will depend on market conditions, the availability of buyers and similar factors. By their nature, our intangible assets may not have a readily ascertainable market value or may not be readily saleable or, if saleable, there may be substantial delays in their liquidation.

We depend on cash from our subsidiaries to service our debt. If we do not receive cash distributions, dividends or other payments from our subsidiaries, we may be unable to make payments on the notes.

        We are dependent upon the earnings and cash flows of, and cash distributions, dividends and other payments from, our subsidiaries to provide the funds necessary to meet our debt service obligations, including the required payments on the notes. If we do not receive such cash distributions, dividends or other payments from our subsidiaries, we may be unable to pay the principal or interest on the notes. In addition, the Subsidiary Guarantors will rely on subsidiaries of their own as a source of funds to meet any obligations that might arise under their guarantees.

        Generally, the ability of a subsidiary to make cash available to its parent is affected by its own operating results and is subject to applicable laws and contractual restrictions contained in its debt instruments and other agreements.

        Although the Senior Secured Credit Facilities limit the extent to which our subsidiaries may restrict their ability to make dividend and other payments to us, these limitations are subject to significant qualifications and exceptions. As a result, although our subsidiaries may have cash, we or our Subsidiary Guarantors may be unable to obtain that cash to satisfy our obligations under the notes or the guarantees, as applicable.

Holdings' guarantee provides little, if any, additional credit support for the notes.

        Holdings is a holding company whose only material asset is the capital stock of AAM Inc. and MPG. Holdings' sole source of operating income and cash flow is currently derived from AAM Inc. and MPG. Accordingly, Holdings is dependent upon the earnings and cash flows of, and cash distributions, dividends and other payments from, AAM Inc. and MPG to provide the funds necessary

S-11


Table of Contents

to meet its obligations under its guarantee. As a result, Holdings' guarantee provides little, if any, additional credit support for the notes.

We may be unable to repurchase the notes upon a change of control.

        Under the indenture governing the notes offered hereby, each holder of notes may require us to repurchase all of such holder's notes at a purchase price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if certain "change of control" events occur. See "Description of the Notes—Change of Control."

        However, it is possible that we will not have sufficient funds when required under the indenture to make the required repurchase of the notes. If we fail to repurchase notes in that circumstance, we will be in default under the indenture governing the notes. If we are required to repurchase a significant portion of the notes, we may require third party financing. We cannot be sure that we would be able to obtain third party financing on acceptable terms, or at all.

        The agreements governing our other indebtedness contain, and future agreements may contain, prohibitions of certain events, including events that would constitute a change of control or an asset sale and including repurchases of or other prepayments in respect of the notes. The exercise by the holders of notes of their right to require us to repurchase the notes pursuant to a change of control offer could cause a default under these other agreements, even if the change of control itself does not, due to the financial effect of such repurchases on us. In the event a change of control offer is required to be made at a time when we are prohibited from purchasing notes, we could attempt to refinance the borrowings that contain such prohibition. If we do not obtain a consent or repay those borrowings, we will remain prohibited from purchasing notes. In that case, our failure to purchase tendered notes would constitute an event of default under the indenture which could, in turn, constitute a default under the other indebtedness. Finally, our ability to pay cash to the holders of notes upon a repurchase may be limited by our then existing financial resources.

There may be no public trading market for the notes.

        We have not applied and do not intend to apply for listing of the notes on any securities exchange or any automated quotation system. As a result, a market for the notes may not develop or, if one does develop, it may not be maintained. If an active market for the notes fails to develop or be sustained, the trading price and liquidity of the notes could be adversely affected.

If you are able to resell your notes, many other factors may affect the price you receive, which may be lower than you believe to be appropriate.

        If you are able to resell your notes, the price you receive will depend on many other factors that may vary over time, including:

        As a result of these factors, you may only be able to sell your notes at prices below those you believe to be appropriate, including prices below the price you paid for them.

S-12


Table of Contents

Our financial performance and other factors could adversely impact our ability to make payments on the notes.

        Our ability to make scheduled payments with respect to our indebtedness, including the notes, will depend on our financial and operating performance, which, in turn, is subject to prevailing economic conditions and to financial, business and other factors beyond our control.

An adverse rating of the notes may cause their trading price to fall.

        If a rating agency rates the notes, it may assign a rating that is lower than the ratings assigned to our other debt. Rating agencies also may lower ratings on the notes or our other debt in the future. If rating agencies assign a lower-than-expected rating or reduce, or indicate that they may reduce, their ratings of our debt in the future, the trading price of the notes could significantly decline.

The indenture governing the notes will not include many of the covenants typically associated with comparably rated debt securities.

        Although the notes are expected to be rated below investment grade at the time of this offering by both Standard & Poor's and Moody's Investors Service, they lack the protection for holders of a number of restrictive covenants typically associated with comparably rated public debt securities, including limitations on the incurrence of additional unsecured indebtedness, payment of dividends and other restricted payments, sale of assets and the use of proceeds therefrom, transactions with affiliates and dividend and other payment restrictions affecting subsidiaries. The primary restrictive covenants contained in the indenture under which the notes will be issued will limit only AAM Inc.'s ability, Holdings' ability and the Subsidiary Guarantors' ability to create certain liens, enter into certain sale-leaseback transactions and consolidate, merge or transfer assets.

Federal and state statutes allow courts, under specific circumstances, to void guarantees and require note holders to return payments received from guarantors.

        AAM Inc.'s creditors or the Subsidiary Guarantors' creditors could challenge the issuance of the notes and the related guarantees as fraudulent conveyances or on other grounds. Under federal bankruptcy law and comparable provisions of state fraudulent transfer laws, the delivery of the notes or the guarantees could be found to be a fraudulent transfer and declared void if a court determined that AAM Inc. or the relevant Subsidiary Guarantor, at the time it incurred the indebtedness evidenced by the note or its guarantee, as applicable, (1) delivered the note or guarantee, as applicable, with the intent to hinder, delay or defraud its existing or future creditors; or (2) received less than reasonably equivalent value or did not receive fair consideration for the delivery of the note or guarantee, as applicable, and any of the following three conditions apply:

        In addition, any payment by AAM Inc. or that guarantor pursuant to the notes or its guarantee, as applicable, could be voided and required to be returned to AAM Inc. or that guarantor, or to a fund for the benefit of the creditors of AAM Inc. or that guarantor, as applicable. In any such case, the right of noteholders to receive payments in respect of the notes from AAM Inc. or any such guarantor, as applicable, would be effectively subordinated to all indebtedness and other liabilities of AAM Inc. or that guarantor.

S-13


Table of Contents

        The indenture governing the notes will limit the liability of each Subsidiary Guarantor on its guarantee to the maximum amount that such Subsidiary Guarantor can incur without risk that its guarantee will be subject to avoidance as a fraudulent transfer. We cannot assure you that this limitation will protect such guarantees from fraudulent transfer challenges or, if it does, that the remaining amount due and collectible under the guarantees would suffice, if necessary, to pay the notes in full when due.

        If a court declares the notes or guarantees to be void, or if the notes or guarantees must be limited or voided in accordance with their terms, any claim a noteholder may make against us or any amounts payable on the notes would, with respect to amounts claimed against AAM Inc. or the guarantors, be subordinated to our indebtedness and the indebtedness of our guarantors, including trade payables. The measures of insolvency for purposes of these fraudulent transfer laws will vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer has occurred. Generally, however, AAM Inc. or a guarantor would be considered insolvent if:

        On the basis of historical financial information, recent operating history and other factors, we believe that AAM Inc. on a consolidated basis, after giving effect to the issuance of the notes and the guarantee of the notes, will not be insolvent, will not have unreasonably small capital for the business in which it is engaged and will not have incurred debts beyond its ability to pay such debts as they mature. We cannot assure you, however, as to what standard a court would apply in making these determinations or that a court would agree with our conclusions in this regard.

A financial failure by any Subsidiary Guarantor may hinder payment on the notes, as well as the enforcement of remedies under any subsidiary guarantees.

        If any of the Subsidiary Guarantors subsequently becomes a debtor subject to insolvency proceedings under the bankruptcy code, it may result in delays in the payment of the notes and in the exercise of enforcement remedies under the notes or any subsidiary guarantees. Provisions under the bankruptcy code or general principles of equity that could result in the impairment of your rights include the automatic stay, avoidance of preferential transfers by a trustee or a debtor-in-possession, limitations of collectability of unmatured interest or attorneys' fees and forced restructuring of the notes.

An increase in market interest rates could result in a decrease in the value of the notes.

        In general, as market interest rates rise, notes bearing interest at a fixed rate generally decline in value because the premium, if any, over market interest rates will decline. Consequently, if you purchase the notes and market interest rates increase, the market value of your notes may decline. We cannot predict the future level of market interest rates.

S-14


Table of Contents

If the notes are rated investment grade at any time by both Standard & Poor's and Moody's Investors Service and no default or event of default has occurred or is continuing, AAM Inc. may elect to suspend the guarantees of the Subsidiary Guarantors, and the holders of the notes will lose the protection of these guarantees.

        The indenture governing the notes contains guarantees by the Subsidiary Guarantors that may, at the election of AAM Inc., be suspended and cease to have any effect from and after the first date when the notes are rated investment grade by both Standard & Poor's and Moody's Investors Service. If at any time after such suspension or cessation the credit rating of the notes is downgraded from an investment grade rating by Standard & Poor's or Moody's Investors Service, then the guarantees by the Subsidiary Guarantors will be reinstated. See "Description of the Notes—Material Covenants—Future subsidiary guarantors."

USE OF PROCEEDS

        We estimate that we will receive net proceeds from this offering of approximately $394,000,000, after deducting the underwriting discounts and our expenses related to this offering, which are payable by us.

        We intend to use the net proceeds of the offering to fund the redemption of 100% of our 6.625% Notes, including the payment of accrued interest, and the remainder for general corporate purposes, which may include the repayment of indebtedness. As of the date of this prospectus supplement, $350 million aggregate principal amount of our 6.625% Notes remained outstanding. Our 6.625% Notes bear interest at the rate of 6.625% per year and mature on October 15, 2022.

DESCRIPTION OF CERTAIN OTHER INDEBTEDNESS

        In 2017, Holdings and AAM Inc. entered into the Credit Agreement (as defined below). In connection with the Credit Agreement, Holdings, AAM Inc. and certain of their restricted subsidiaries entered into a Collateral Agreement and Guarantee Agreement with the financial institutions party thereto. The Credit Agreement included a $100.0 million term loan A facility (the "Term Loan A Facility"), a $1.55 billion term loan B facility (the "Term Loan B Facility") and a $932 million multi-currency revolving credit facility (the "Revolving Credit Facility," and together with the Term Loan A Facility and the Term Loan B Facility, the "Senior Secured Credit Facilities").

        In July 2019, Holdings, AAM Inc., and certain subsidiaries of Holdings entered into the First Amendment (the "First Amendment") to the Credit Agreement. The First Amendment, among other things, established $340 million in incremental term loan A commitments under the Credit Agreement with a maturity date of July 29, 2024, reduced the availability under the Revolving Credit Facility from $932 million to $925 million and extended the maturity date of the Revolving Credit Facility from April 6, 2022 to July 29, 2024, and modified the applicable margin with respect to interest rates under the Term Loan A Facility and interest rates and commitment fees under the Revolving Credit Facility. The applicable margin and the maturity date for the Term Loan B Facility remain unchanged. The proceeds of $340 million from the loans borrowed under such incremental term loan A commitments were used to repay all of the outstanding loans under the existing Term Loan A Facility and a portion of the outstanding Term Loan B Facility, resulting in no additional indebtedness. This also satisfies all principal payment requirements under the Term Loan B Facility until maturity in 2024. We expensed $5.1 million for the write-off of the unamortized debt issuance costs related to the existing Term Loan A Facility and a portion of the unamortized debt issuance costs related to our Term Loan B Facility that we had been amortizing over the expected life of the borrowings.

        In December 2019, we used a portion of the cash proceeds from the Casting Sale to make a payment on our Term Loan B Facility, which included a principal payment of $59.8 million and $0.4 million in accrued interest. We also expensed approximately $1.0 million for the write-off of the unamortized debt issuance costs that we had been amortizing over the expected life of the borrowing.

        In April 2020, Holdings, AAM Inc., and certain subsidiaries of Holdings entered into the Second Amendment (the "Second Amendment") to the Credit Agreement (as amended by the First Amendment and the Second Amendment, the "Credit Agreement"). For the period from April 1, 2020 through March 31, 2022 (the "Amendment Period"), the Second Amendment, among other things replaced the total net leverage ratio covenant with a new senior secured net leverage ratio covenant, reduced the minimum levels of the cash interest expense coverage ratio covenant, and modified certain covenants restricting the ability of Holdings, AAM and certain subsidiaries of Holdings to create, incur, assume or permit to exist certain additional indebtedness and liens and to make certain restricted payments, voluntary payments and distributions. The Second Amendment also increased the maximum levels of the total net leverage ratio covenant after the Amendment Period, modified the applicable margin with respect to interest rates under the Term Loan A Facility and interest rates and commitment fees under the Revolving Credit Facility, and increased the minimum adjusted London Interbank Offered Rate for Eurodollar-based loans under the Term Loan A Facility and Revolving Credit Facility. The applicable margin for the Term Loan B Facility remains unchanged.

        At March 31, 2020, $691.4 million was available under the Revolving Credit Facility. This availability reflects a reduction of $33.6 million for standby letters of credit issued against the facility. Further, in April 2020, we drew an additional $150.0 million on the Revolving Credit Facility. The proceeds of the Revolving Credit Facility are used for general corporate purposes.

        The Senior Secured Credit Facilities provide back-up liquidity for our foreign credit facilities. We intend to use the availability of long-term financing under the Senior Secured Credit Facilities to refinance any current maturities related to such debt agreements that are not otherwise refinanced on a

long-term basis in their local markets, except where otherwise reclassified to current portion of long-term debt on our Consolidated Balance Sheet.

6.625% Notes

        In 2012, we issued $550.0 million of 6.625% senior unsecured notes due 2022. Net proceeds from the 6.625% Notes were used to fund the purchase and redemption of $250.0 million of the outstanding 5.25% senior unsecured notes, including the payment of interest, the redemption of $42.5 million aggregate principal amount of our 9.25% notes, certain pension obligations and for other general corporate purposes.

        In the second quarter of 2018, we voluntarily redeemed a portion of our 6.625% Notes. This resulted in a principal payment of $100.0 million, and a payment of $0.8 million in accrued interest. During 2018, we expensed $0.8 million for the write-off of a portion of the remaining unamortized debt issuance costs that we had been amortizing over the expected life of the borrowing and $3.3 million for an early redemption premium.

        In January 2020, we issued an irrevocable notice to the holders of our 6.625% Notes to voluntarily redeem a portion of our 6.625% Notes in February 2020. This resulted in a principal payment of $100 million and $2.0 million in accrued interest in February 2020. We expensed approximately $0.4 million for the write-off of the unamortized debt issuance costs that we had been amortizing over the expected life of the borrowing, and approximately $1.1 million for the payment of an early redemption premium. We expect to redeem the remainder of the outstanding 6.625% Notes with the proceeds from this offering.

6.50% Notes due 2027 and 6.25% Notes due 2025

        On March 23, 2017, we issued $700.0 million in aggregate principal amount of 6.25% senior notes due 2025 and $500.0 million in aggregate principal amount of 6.50% senior notes due 2027. Proceeds from the 6.25% Notes due 2025 and the 6.50% Notes, together with borrowings under the Senior Secured Credit Facilities, were used primarily to fund the cash consideration related to our acquisition of MPG, related fees and expenses, refinance certain existing indebtedness of MPG and borrowings under our previous revolving credit facility, which has been replaced by our new Revolving Credit Facility. We incurred debt issuance costs of $37.2 million in 2017 related to the 6.25% Notes due 2025 and the 6.50% Notes.

6.25% Notes Due 2026

        In 2018, we issued $400.0 million in aggregate principal amount of 6.25% senior notes due 2026. Proceeds from the 6.25% Notes due 2026 were used primarily to fund the tender offer for and subsequent redemption of our previously outstanding 6.25% senior notes due 2021. We paid debt issuance costs of $6.6 million during 2018 related to the 6.25% Notes due 2026.

Foreign Credit Facilities

        We utilize local currency credit facilities to finance the operations of certain foreign subsidiaries. At March 31, 2020, $102.7 million was outstanding under our foreign credit facilities and an additional $86.0 million was available, as compared to December 31, 2019, when $106.0 million was outstanding under our foreign credit facilities and an additional $89.1 million was available.

DESCRIPTION OF THE NOTES

        We will issue 6.875% senior notes due 2028 (the "notes") pursuant to an indenture dated as of November 3, 2011, as amended and supplemented from time to time, among American Axle & Manufacturing, Inc., as issuer, American Axle & Manufacturing Holdings, Inc., as guarantor, the Subsidiary Guarantors (as defined herein), and U.S. Bank National Association, as trustee. The terms of the notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act of 1939, as amended.

        The following description is only a summary of the material provisions of the notes and the indenture. This description does not purport to be complete, and is subject to, and is qualified in its entirety by reference to, all of the provisions of the notes and the indenture. We urge you to read the indenture and the form of the notes, which you may obtain from us upon request. You will find the definitions of capitalized terms used in this description under the heading "—Certain Definitions." As used in this description, all references to the "Issuer," "we," "us" or "our" mean American Axle & Manufacturing, Inc., excluding, unless otherwise expressly stated or the context otherwise requires, its subsidiaries, all references to "Holdings" mean American Axle & Manufacturing Holdings, Inc., our parent corporation, excluding, unless otherwise expressly stated or the context otherwise requires, its subsidiaries, and all reference to "MPG" mean Metaldyne Performance Group Inc., a wholly owned subsidiary of Holdings, excluding, unless otherwise expressly stated or the context otherwise requires, its subsidiaries. Holdings has no material operations or assets other than its ownership of 100% of the issued and outstanding common stock of the Issuer and MPG.

General

        The notes initially will be limited to $400 million aggregate principal amount. The indenture provides that we have the ability to issue additional notes in series, including additional notes of the same series, having the same ranking and the same interest rate, maturity and other terms, as the notes issued hereby. Any additional notes having the same terms as the notes offered hereby and designated as the same series and class of notes will, together with the notes offered hereby, constitute a single series of the notes under the indenture. However, in the event that any such additional notes are not fungible with the notes for U.S. federal income tax purposes, such non-fungible additional notes will be issued with a separate CUSIP number so that they are distinguishable from the notes. The notes will mature on July 1, 2028. The notes will be payable at the office of the paying agent, which initially will be an office or agency of the trustee, or an office or agency maintained by us for such purpose, in the Borough of Manhattan, The City of New York.

        The notes will bear interest at the rate of 6.875% per year on the principal amount from June 12, 2020, or from the most recent date to which interest has been paid or provided for, until July 1, 2028. Interest will be payable on the notes semi-annually in arrears on January 1 and July 1 of each year, commencing on January 1, 2021, to holders of record at the close of business on the December 15 or June 15 immediately preceding such interest payment date. Each payment of interest on the notes will include interest accrued from the period commencing on and including the immediately preceding interest payment day (or, if none, June 12, 2020) through the day before the applicable interest payment date (or redemption date, as the case may be). Any payment required to be made on any day that is not a business day will be made on the next succeeding business day.

        Interest will cease to accrue on a note upon its maturity or redemption. We may not reissue a note that has matured or been redeemed or otherwise canceled, except for registration of transfer, exchange or replacement of such note.

Guarantees

        Holdings, MPG and each of the other Subsidiary Guarantors will, jointly and severally, fully and unconditionally guarantee on a senior unsecured basis the Issuer's obligations under the notes and the indenture.

        Each guarantee by a Subsidiary Guarantor will provide by its terms that it will be automatically, fully and unconditionally released and discharged upon:

        The obligations of each Subsidiary Guarantor under its guarantee will be limited as necessary to prevent that guarantee from constituting a fraudulent conveyance or fraudulent transfer under applicable law.

Ranking

        The indebtedness evidenced by the notes and the guarantees will be unsecured and will rank pari passu in right of payment to the senior indebtedness of the Issuer and the Guarantors, respectively.

        The notes are unsecured obligations of the Issuer. Secured debt and other secured obligations of the Issuer (including obligations with respect to the Credit Agreement) will be effectively senior to the notes to the extent of the value of the assets securing such debt or other obligations.

        As of March 31, 2020, after giving effect to the offering of the notes, the planned redemption of the remaining $350 million principal amount of our 6.625% Notes, there would have been outstanding:

        Not all of our Subsidiaries will guarantee the notes. In the event of a bankruptcy, liquidation or reorganization of any of our non-guarantor Subsidiaries, including any of our foreign Subsidiaries, holders of their indebtedness and their trade creditors will generally be entitled to payment of their claims from the assets of those entities before any assets are made available for distribution to us. As a result, the notes will effectively be subordinated to the prior payment of all of the liabilities of our non-guarantor Subsidiaries.

        As of March 31, 2020, the non-guarantor Subsidiaries of AAM Inc. and MPG had total assets (net of intercompany receivables) of $2,789.8 million and total liabilities (net of intercompany notes and payables) of $913.5 million (including indebtedness of $102.7 million).

Optional Redemption

        On and after July 1, 2023, we will be entitled at our option to redeem all or a portion of these notes upon not less than 10 nor more than 60 days' notice, at the redemption prices (expressed in percentages of principal amount on the redemption date), plus accrued and unpaid interest to the redemption date (subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on July 1 of the years set forth below:

2023

    103.438 %

2024

    101.719 %

2025 and thereafter

    100.000 %

        Prior to July 1, 2023, we will be entitled at our option to redeem all or a portion of the notes at a redemption price equal to 100% of the principal amount of the notes plus the Applicable Premium plus accrued and unpaid interest to the redemption date (subject to the right of holders on the relevant record date to receive interest due on the relevant interest payment date). Notice of such redemption must be mailed by first-class mail to each holder's registered address or delivered electronically, not less than 10 nor more than 60 days prior to the redemption date.

        In addition, we may on any one or more occasions prior to July 1, 2023 redeem up to 35% of the original principal amount of the notes (calculated after giving effect to any issuance of additional notes) with the Net Cash Proceeds of one or more Equity Offerings at a redemption price of 106.875% of the principal amount thereof plus accrued and unpaid interest, if any, to the applicable redemption date (subject to the right of holders on the relevant record date to receive interest due on the relevant interest payment date); provided that:

        Holders of the notes to be redeemed will receive notice of such redemption at least 10 days, but not more than 60 days, before the redemption date. At the Issuer's option, a notice of redemption may be conditioned on the satisfaction of one or more conditions. If so conditioned, such a notice of redemption shall state that, in the Issuer's discretion, the redemption date may be delayed until such time as any or all of such conditions shall be satisfied (or waived by the Issuer in its discretion), or such redemption may not occur and such notice may be rescinded in the event that any or all of such conditions have not been satisfied (or waived by the Issuer in its discretion) by the redemption date, or the redemption date so delayed. Once a notice of redemption is delivered (or, in the event of a notice of conditional redemption, once the conditions set forth therein are satisfied), the notes to be redeemed will become due and payable on the redemption date, or the redemption date so delayed, at the redemption price, plus accrued and unpaid interest to the redemption date, or the redemption date so delayed. If less than all the notes are to be redeemed at any time, the trustee will select notes to be redeemed on a pro rata basis or by any other method the trustee deems fair and appropriate. Unless we default in payment of the redemption price, on and after the date of redemption, or the redemption date so delayed, interest will cease to accrue on the notes or portions thereof called for redemption.

Change of Control

        Upon the occurrence of a Change of Control, the Issuer will make an offer (a "Change of Control Offer") to each holder to repurchase all or any part of each holder's notes at a purchase price (the "Change of Control Purchase Price") equal to 101% of the principal amount thereof, plus accrued and

S-22


Table of Contents

unpaid interest, if any, to the repurchase date. Within 30 days following any Change of Control, the Issuer will (i) cause a notice of the Change of Control Offer to be sent at least once to the Dow Jones News Service or similar business news service in the United States; and (ii) send, by first-class mail or deliver electronically, with a copy to the trustee, a notice to each registered holder stating: (1) that a Change of Control has occurred and a Change of Control Offer is being made pursuant to the indenture and that all notes timely tendered will be accepted for payment; (2) the Change of Control Purchase Price and the repurchase date, which shall be, subject to any contrary requirements of applicable law, a business day no earlier than 10 days nor later than 60 days from the date such notice is mailed (the "Change of Control Payment Date"); (3) the circumstances and relevant facts regarding the Change of Control (including information with respect to pro forma historical income, cash flow and capitalization after giving effect to the Change of Control); and (4) the procedures that holders of notes must follow in order to tender their notes (or portions thereof) for payment, and the procedures that holders of notes must follow in order to withdraw an election to tender notes (or portions thereof) for payment.

        The Issuer shall comply with the requirements of Rule 14e of the Exchange Act, and any other securities laws or regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of notes in connection with a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with the terms of the notes or the indenture, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the notes or the indenture by virtue of such compliance.

        On the Change of Control Payment Date, the Issuer will, to the extent lawful, (1) accept for payment all notes or portions thereof properly tendered pursuant to the Change of Control Offer; (2) deposit with the paying agent an amount equal to the Change of Control Purchase Price in respect of all notes or portions thereof properly tendered and (3) deliver or cause to be delivered to the trustee the notes properly accepted together with an officers' certificate stating the aggregate principal amount of notes or portions thereof being purchased by the Issuer. The paying agent will promptly mail to each registered holder of notes properly tendered the Change of Control Purchase Price for such notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each holder a new note equal in principal amount to any unpurchased portion of the notes surrendered by such holder, if any; provided that each such new note will be in a principal amount of $1,000 or an integral multiple thereof.

        The Issuer will publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date. The Issuer will not be required to make a Change of Control Offer upon a Change of Control if a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth herein and all other provisions of the indenture and terms of the notes applicable to a Change of Control Offer made by the Issuer and purchases all notes validly tendered and not withdrawn under such Change of Control Offer.

Material Covenants

        Consolidation, merger, sale or conveyance.    (a) The indenture provides that neither the Issuer nor Holdings may consolidate with or merge into any other Person or convey, transfer or lease their properties and assets substantially as an entirety to any Person, unless:

S-23


Table of Contents

        In case of any such consolidation, merger, conveyance or transfer, the successor entity will succeed to and be substituted for the Issuer or Holdings, as the case may be, as obligor or guarantor on the notes, as the case may be, with the same effect as if it had been named in the indenture as the Issuer or Holdings, as the case may be.

        (b)   No Subsidiary Guarantor may consolidate with or merge into any other Person or convey, transfer or lease their properties and assets substantially as an entirety to any Person, unless:

        Limitation on liens.    The Issuer and Holdings will not, and will not permit any Restricted Subsidiary to, create, incur, issue, assume or guarantee any indebtedness for money borrowed ("Debt") secured by a Mortgage upon any Operating Property, or upon shares of Capital Stock or Debt issued by any Restricted Subsidiary and owned by the Issuer or Holdings or any Restricted Subsidiary, whether owned at the date of the indenture (November 3, 2011) or thereafter acquired, without effectively providing concurrently that the notes of each series then outstanding under the indenture are secured equally and ratably with or, at our option, prior to such Debt so long as such Debt shall be so secured.

        The foregoing restriction shall not apply to, and there shall be excluded from Debt in any computation under such restriction, Debt secured by:

S-24


Table of Contents

        Notwithstanding the restrictions described above, the Issuer, Holdings and any Restricted Subsidiaries may create, incur, issue, assume or guarantee Debt secured by Mortgages without equally and ratably securing the notes of each series then outstanding if, at the time of such creation, incurrence, issuance, assumption or guarantee, after giving effect thereto and to the retirement of any Debt which is concurrently being retired, the aggregate amount of all such Debt secured by Mortgages which would otherwise be subject to such restrictions (other than any Debt secured by Mortgages permitted as described in clauses (1) through (7) of the immediately preceding paragraph) plus all Attributable Debt of the Issuer, Holdings and the Restricted Subsidiaries in respect of Sale and Leaseback Transactions with respect to Operating Properties (with the exception of such transactions which are permitted under clauses (1) through (4) of the first sentence of the first paragraph under "—Limitation on sale and leaseback transactions" below) does not exceed 10% of Consolidated Net Tangible Assets.

        Limitation on sale and leaseback transactions.    The Issuer and Holdings will not, and will not permit any Restricted Subsidiary to, enter into any Sale and Leaseback Transaction with respect to any Operating Property unless:

S-25


Table of Contents

        Future subsidiary guarantors.    The Issuer will cause each of the Subsidiaries that is not a Subsidiary Guarantor and that guarantees any Guarantee Indebtedness of the Issuer or any Guarantor to execute and deliver to the trustee a supplemental indenture pursuant to which such Subsidiary will unconditionally guarantee, on a joint and several basis, the full and prompt payment of the principal of, premium, if any, and interest in respect of the notes on an unsecured and unsubordinated basis and all other obligations under the indenture.

        The guarantee of the notes by any Subsidiary Guarantor will be released and discharged as described under "—Guarantees."

        The obligations of each Subsidiary Guarantor will be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor and after giving effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its guarantee or pursuant to its contribution obligations under the indenture, result in the obligations of such Subsidiary Guarantor under its guarantee not constituting a fraudulent conveyance or fraudulent transfer under federal or state law.

        Following the first day (the "Suspension Date"):

        Holdings, the Issuer and their Subsidiaries will not be subject to the provisions of this covenant.

        In addition, upon the occurrence of a Suspension Date, the Issuer may elect, by delivering written notice thereof to the trustee, to suspend the guarantees of the Subsidiary Guarantors.

        If at any time the notes' credit rating is downgraded from an Investment Grade Rating by any Ratings Agency or if a Default or Event of Default occurs and is continuing, then (i) this covenant will

S-26


Table of Contents

thereafter be reinstated, unless and until the notes subsequently attain an Investment Grade Rating and no Default or Event of Default is in existence (in which event this covenant shall no longer be in effect for such time that the notes maintain an Investment Grade Rating and no Default or Event of Default is in existence) and (ii) the guarantees of the Subsidiary Guarantors previously suspended will be automatically reinstated.

        There can be no assurance that the notes will ever achieve or maintain an Investment Grade Rating.

Events of Default; Waiver and Notice

        An event of default is defined in the indenture as:

        When we refer to a "Significant Subsidiary," we mean any Subsidiary that would constitute a "significant subsidiary" within the meaning of Article 1 of Regulation S-X of the Securities Act of 1933, as amended (the "Securities Act") as in effect on the date of the indenture.

        The indenture provides that:

S-27


Table of Contents

        Under the indenture, the trustee must give to the holders of notes notice of all uncured defaults known to it with respect to the notes within 90 days after such a default occurs (the term default to include the events specified above without notice or grace periods); provided that, except in the case of default in the payments of principal of, any premium on, any of the notes, the trustee will be protected in withholding such notice if it in good faith determines that the withholding of such notice is in the interests of the holders of the notes.

        No holder of any notes may institute any action under the indenture unless:

        The holders of a majority in aggregate principal amount of the notes affected and then outstanding will have the right, subject to certain limitations, to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the notes. The indenture provides that if an event of default occurs and is continuing, the trustee, in exercising its rights and powers under the indenture, will be required to use the degree of care of a prudent man in the conduct of his own affairs. The indenture further provides that the trustee shall not be required to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties under the indenture unless it has reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is reasonably assured to it.

        We must furnish to the trustee within 120 days after the end of each fiscal year a statement of the Issuer signed by one of the officers of the Issuer to the effect that a review of our activities during such year and our performance under the indenture and the terms of the notes has been made, and, to the knowledge of the signatories based on such review, we have complied with all conditions and covenants of the indenture or, if we are in default, specifying such default.

Modification of the Indenture

        The Issuer and the trustee may, without the consent of the holders of the notes issued under the indenture, enter into supplemental indentures for, among others, one or more of the following purposes:

        With certain exceptions, the indenture, the Holdings guarantee or the rights of the holders of the notes may be modified by us and the trustee with the consent of the holders of a majority in aggregate principal amount of the notes then outstanding, but no such modification may be made without the consent of the holder of each outstanding note affected thereby that would:

Discharge of the Indenture

        The Issuer may satisfy and discharge its obligations under the indenture by delivering to the trustee for cancelation all outstanding notes or by depositing with the trustee or the paying agent after the notes have become due and payable, whether at stated maturity, or any redemption date, or otherwise, cash sufficient to pay all of the outstanding notes and paying all other sums payable under the indenture by the Issuer.

Governing Law

        The indenture, the notes and the guarantee are governed by and construed in accordance with the laws of the State of New York.

S-29


Table of Contents

Book-Entry System

        The notes will be represented by one or more global securities. Each global security will be deposited with, or on behalf of, The Depository Trust Company ("DTC"), and be registered in the name of a nominee of DTC. Except circumstances described below, the notes will not be issued in definitive form.

        Upon the issuance of a global security, DTC will credit on its book-entry registration and transfer system the accounts of persons designated by the underwriters with the respective principal amounts of the notes represented by the global security. Ownership of beneficial interests in a global security will be limited to persons that have accounts with DTC or its nominee ("participants") or persons that may hold interests through participants. Owners of beneficial interests in the notes represented by the global securities will hold their interests pursuant to the procedures and practices of DTC. Ownership of beneficial interests in a global security will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to interests of persons other than participants). The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. Such limits and such laws may impair the ability to transfer beneficial interests in a global security.

        So long as DTC or its nominee is the registered owner of a global security, DTC or its nominee, as the case may be, will be considered the sole owner or holder of the notes presented by that global security for all purposes under the indenture. Except as provided below, owners of beneficial interests in a global security will not be entitled to have notes represented by that global security registered in their names, will not receive or be entitled to receive physical delivery of notes in definitive form and will not be considered the owners or holders thereof under the indenture. Beneficial owners will not be holders and will not be entitled to any rights provided to the holders of notes under the global securities or the indenture. Payment of principal amounts on notes registered in the name of DTC or its nominee will be made to DTC or its nominee, as the case may be, as the registered owner of the relevant global security. None of the Issuer, Holdings, the trustee, any paying agent or the registrar for the notes will have any responsibility or liability for any aspect of the records relating to or payment made on account of beneficial interests in a global security or for maintaining, supervising or reviewing any records relating to such beneficial interests.

        We expect that DTC or its nominees, upon receipt of any payment of the principal amount, will credit immediately participants' accounts with payments in amounts proportionate to their respective beneficial interests in the principal amount of the relevant global security as shown on the records of DTC or its nominee. We also expect that payments by participants to owners of beneficial interests in a global security held through such participants will be governed by standing instructions and customary practices, as is the case with securities held for the accounts of customers in bearer form or registered in "street name," and will be the responsibility of such participants.

        If DTC is at any time unwilling or unable to continue as a depository and a successor depository is not appointed by us within 90 days or if an event of default has occurred and is continuing, we will issue notes in definitive form in exchange for the entire global security for the notes. In any such instance, an owner of a beneficial interest in a global security will be entitled to physical delivery in definitive form of notes represented by such global security equal in principal amount to such beneficial interest and to have such notes registered in its name. Notes so issued in definitive form will be issued as registered notes in denominations of $1,000 principal amount and integral multiples thereof, unless otherwise specified by the Issuer.

MATERIAL U.S. FEDERAL INCOME TAX CONSIDERATIONS

        The following is a general discussion of material U.S. federal income tax consequences of the acquisition, ownership and disposition of the notes by initial holders of the notes, but does not purport to be a complete analysis of all the potential tax considerations. This discussion is based upon the U.S. Internal Revenue Code of 1986, as amended (the "Code"), the Treasury regulations thereunder and administrative rulings and court decisions, all as of the date hereof, and all of which are subject to change, possibly retroactively. Unless otherwise stated, this discussion is limited to the tax consequences to those persons who are original beneficial owners of the notes ("Holders") who purchase notes at their original issue price for cash and who hold such notes as capital assets within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not consider any specific facts or circumstances that may apply to a particular Holder (including, for example, a financial institution, dealers and certain traders in securities, an insurance company, a tax-exempt organization, a partnership or other pass-through entity or arrangement for U.S. federal income tax purposes (or an investor therein), an expatriate, a real estate investment trust, a regulated investment company, a holder of the 6.625% Notes whose notes are redeemed in a substantially concurrent transaction, a person subject to special tax accounting rules that apply as a result of gross income with respect to the notes being taken into account on an applicable financial statement or a person that holds securities as part of a straddle, hedge, conversion transaction, or other integrated investment). This discussion also does not address the tax consequences to U.S. Holders (as defined herein) that have a functional currency other than the U.S. dollar. In addition, this discussion does not address U.S. federal alternative minimum tax, the Medicare tax on net investment income or estate and gift tax consequences or any aspect of state, local or foreign taxation. We have not sought any ruling from the Internal Revenue Service (the "IRS") with respect to the statements made and the conclusions reached in this discussion, and we cannot assure you that the IRS will agree with such statements and conclusions.

        For purposes of this discussion, a "U.S. Holder" means a Holder that is, for U.S. federal income tax purposes (1) an individual who is a citizen or resident of the United States, (2) a corporation or other entity taxable as a corporation created or organized in the United States or under the laws of the United States, any state thereof or the District of Columbia, (3) an estate whose income is includible in gross income for U.S. federal income tax purposes regardless of its source, or (4) a trust (a) whose administration is subject to the primary supervision of a U.S. court and which has one or more U.S. persons who have the authority to control all substantial decisions of the trust or (b) if a valid election to be treated as a U.S. person is in effect with respect to such trust. A Non-U.S. Holder is a Holder that is neither a U.S. Holder nor a partnership for U.S. federal income tax purposes.

        If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds the notes, the U.S. federal income tax treatment of its partners generally will depend on the status of its partners and the activities of the partnership. If you are a partner of a partnership acquiring the notes, you should consult your tax advisor about the tax consequences of acquiring, holding and disposing of the notes.

        In certain circumstances, we may be obligated to pay amounts in excess of stated principal on the notes or retire the notes before their stated maturity dates (see "Description of the Notes—Optional Redemption," "Description of the Notes—Change of Control"). Notwithstanding these possibilities, we do not believe that the notes are contingent payment debt instruments for U.S. federal income tax purposes, and, consequently, we do not intend to treat the notes as contingent payment debt instruments. If, notwithstanding our view, the notes were treated as contingent payment debt instruments, a Holder subject to U.S. federal income taxation generally could be required to accrue ordinary income at a rate in excess of the stated interest rate on such notes and to treat as ordinary income (rather than capital gain) any gain recognized on a sale or other taxable disposition of such

S-35


Table of Contents

notes. The remainder of this discussion assumes that the notes will not be treated as contingent payment debt instruments for U.S. federal income tax purposes.

        PROSPECTIVE INVESTORS ARE URGED TO CONSULT THEIR INDEPENDENT TAX ADVISORS REGARDING THE U.S. FEDERAL TAX CONSEQUENCES OF ACQUIRING, HOLDING, AND DISPOSING OF THE NOTES, AS WELL AS ANY TAX CONSEQUENCES THAT MAY ARISE UNDER THE LAWS OF ANY FOREIGN, STATE, LOCAL, OR OTHER TAXING JURISDICTION.

U.S. Federal Income Taxation of U.S. Holders

Payments of Interest

        Interest on the notes generally will be taxable to a U.S. Holder as ordinary interest income at the time it is accrued or is received in accordance with the U.S. Holder's method of accounting for tax purposes.

Taxable Disposition

        In general, a U.S. Holder will recognize gain or loss upon the sale, exchange, redemption or other taxable disposition of the notes measured by the difference between (1) the amount of cash and fair market value of property received (except to the extent such cash or property is attributable to accrued but unpaid interest, which is treated as interest as described above) and (2) the U.S. Holder's adjusted tax basis in the notes. A U.S. Holder's adjusted tax basis in the notes generally will equal the cost of the notes to the U.S. Holder. Any gain or loss generally will be long-term capital gain or loss if such notes had been held by such U.S. Holder for more than one year at the time of such sale, exchange, redemption or other taxable disposition. In the case of non-corporate U.S. Holders, long-term capital gain is subject to preferential rates of U.S. federal income tax. The deductibility of capital losses by U.S. Holders is subject to limitations.

U.S. Federal Income Taxation of Non-U.S. Holders

Payments of Interest

        Subject to the discussions of FATCA and backup withholding below, payments of interest on the notes to a Non-U.S. Holder, that are not effectively connected with a U.S. trade or business of the Non-U.S. Holder, generally will not be subject to U.S. federal withholding tax, provided that:

S-36


Table of Contents

        The requirements set forth in the bulleted clauses above are known as the "Portfolio Interest Exception."

        If a Non-U.S. Holder cannot satisfy the requirements of the Portfolio Interest Exception, payments of interest made to such Non-U.S. Holder will be subject to 30% U.S. federal withholding tax unless the beneficial owner of the note provides us or our agent, as the case may be, with a properly executed:

        The certification requirements described above also may require the Non-U.S. Holder to provide its U.S. taxpayer identification number.

        Each Non-U.S. Holder is urged to consult its own independent tax advisor about the specific methods for satisfying these requirements. A claim for exemption will not be valid if the person receiving the applicable form has actual knowledge or reason to know that statements on the form are false.

        If interest on the notes is effectively connected with a U.S. trade or business of the Non-U.S. Holder (and if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment), the Non-U.S. Holder, although exempt from the U.S. federal withholding tax described above (provided that the certification requirements described above are satisfied), will be subject to U.S. federal income tax on such interest on a net income basis in the same manner as if it were a U.S. Holder. In addition, if such Non-U.S. Holder is a foreign corporation and interest on the note is effectively connected with its U.S. trade or business (and if required by an applicable treaty, attributable to a U.S. permanent establishment), such Holder may be subject to a branch profits tax equal to 30% (or lower income tax treaty rate) in respect of such interest.

Taxable Disposition

        Except with respect to accrued and unpaid interest and subject to the discussion of backup withholding below, a Non-U.S. Holder will not be subject to U.S. federal income tax on gain realized on the sale, exchange or other disposition of the notes, unless (a) that Holder is an individual who is present in the United States for 183 days or more during the taxable year and certain other requirements are met or (b) the gain is effectively connected with the conduct of a U.S. trade or business of the Holder (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment or fixed base). Accrued and unpaid interest realized on a sale, exchange or other disposition of a note will be subject to U.S. federal income tax to the extent interest would have been subject to U.S. federal income tax as described under "—U.S. Federal Income Taxation of Non-U.S. Holders—Payments of Interest."

        Gain realized by a Non-U.S. Holder described in clause (a) above generally will be subject to tax at a rate of 30% (or a lower applicable income tax treaty rate, provided certain certification requirements are met) to the extent of the excess of such Holder's U.S.-source capital gains during the tax year over U.S.-source capital losses during such tax year. Gain realized by a Non-U.S. Holder described in clause (b) above generally will be subject to U.S. federal income tax in the same manner as a U.S. Holder. In addition, if such Non-U.S. Holder is a foreign corporation and gain on the note is effectively connected with its U.S. trade or business (and if required by an applicable treaty, is

S-37


Table of Contents

attributable to a U.S. permanent establishment), such Holder may be subject to a branch profits tax equal to 30% (or lower income tax treaty rate) in respect of such gain.

Information Reporting and Backup Withholding

        We will, where required, report to Holders and the IRS the amount of any interest paid on the notes in each calendar year and the amounts of U.S. federal tax withheld, if any, with respect to payments. A noncorporate U.S. Holder may be subject to information reporting and to backup withholding at a current rate of 24% with respect to payments of principal and interest made on the notes, or on proceeds of the disposition of the notes before maturity, unless that U.S. Holder provides a correct taxpayer identification number or proof of an applicable exemption, and otherwise complies with applicable requirements of the information reporting and backup withholding rules.

        Under the Treasury regulations, backup withholding generally will not apply to payments made by us or our agent (in its capacity as such) to a Non-U.S. Holder if such Non-U.S. Holder has provided the required certification that it is not a U.S. person on an IRS Form W-8BEN or IRS Form W-8BEN-E, as applicable, or has otherwise established an exemption (provided that neither we nor our agent has actual knowledge that such Holder is a U.S. person or that the conditions of any exemption are not in fact satisfied).

        Payments of the proceeds from the sale of the notes to or through a foreign office of a broker will not be subject to information reporting or backup withholding, except if the broker is (1) a U.S. person, (2) a "controlled foreign corporation," (3) a foreign person 50% of more of whose gross income for certain periods is effectively connected with a U.S. trade or business or (4) a foreign partnership, if at any time during its taxable year, one or more of its partners are U.S. persons who in the aggregate hold more than 50% of the income or capital interest in the partnership or if, at any time during its taxable year, the foreign partnership is engaged in a U.S. trade or business, unless the Non-U.S. Holder establishes an exception as specified in the Treasury regulations regarding backup withholding and information reporting, as applicable.

        Backup withholding is not an additional tax. Any amount withheld under the backup withholding rules will be refunded or credited against the Holder's U.S. federal income tax liability, provided that the required information is furnished to the IRS in a timely manner.

FATCA

        Sections 1471-1474 of the Code and the Treasury regulations thereunder (commonly referred to as "FATCA"), when applicable, impose a U.S. federal withholding tax of 30% on certain types of payments, including payments of U.S. source interest, made to (i) "foreign financial institutions" unless they agree to collect and disclose to the IRS information regarding their direct and indirect U.S. account holders or (ii) certain non-financial foreign entities unless they certify that they do not have any "substantial United States owners" (as defined in the Code) or furnish identifying information regarding each substantial United States owner (generally by providing an IRS Form W-8BEN-E). In certain circumstances, the relevant foreign financial institution or non-financial foreign entity may qualify for an exemption from these rules, which exemption is typically evidenced by providing appropriate documentation (such as an IRS Form W-8BEN-E). In addition, an intergovernmental agreement between the United States and the jurisdiction of a foreign financial institution may modify these rules.

        You are urged to consult your own tax advisors regarding FATCA and the application of these requirements to your investment in the notes.

        The underwriting agreement provides that the underwriters will purchase all the notes if any of them are purchased. The underwriting agreement also provides that if an underwriter defaults, the purchase commitments of non-defaulting underwriters may also be increased or the offering may be terminated.

        The underwriters initially propose to offer the notes to the public at the public offering price that appears on the cover page of this prospectus supplement. The underwriters may offer the notes to selected dealers at the public offering price. After the initial offering, the underwriters may change the public offering price and any other selling terms. The underwriters may offer and sell notes through certain of their affiliates. The expenses of the offering, not including the underwriting discount, are estimated to be approximately $1,000,000 and are payable by us.

        In the underwriting agreement, we have agreed that we will indemnify the underwriters against certain liabilities, including liabilities under the Securities Act, or contribute to payments that the underwriters may be required to make in respect of those liabilities.

        The notes are a new issue of securities, and there is currently no established trading market for the notes. We do not intend to apply for the notes to be listed on any securities exchange or to arrange for the notes to be quoted on any quotation system. Certain of the underwriters have advised us that they intend to make a market in the notes, but they are not obligated to do so. The underwriters may discontinue any market making in the notes at any time at their sole discretion. Therefore, we cannot assure you that a liquid trading market will develop for the notes, that you will be able to sell your notes at a particular time or that the prices that you receive when you sell will be favorable.

        In connection with this offering of the notes, the underwriters may engage in overallotment, stabilizing transactions and syndicate covering transactions in accordance with Regulation M under the Exchange Act. Overallotment involves sales in excess of the offering size, which creates a short position for the underwriters. Stabilizing transactions involve bids to purchase the notes in the open market for the purpose of pegging, fixing or maintaining the price of the notes, as applicable. Syndicate covering transactions involve purchases of the notes in the open market after the distribution has been completed in order to cover short positions. Stabilizing transactions and syndicate covering transactions may cause the price of the notes to be higher than it would otherwise be in the absence of those

S-39


Table of Contents

transactions. If any underwriter engages in stabilizing or syndicate covering transactions, it may discontinue them at any time.

        The underwriters, together with their respective affiliates, are full service financial institutions engaged in various activities, which activities may include securities trading, commercial and investment banking, financial advisory, investment management, investment research, principal investment, hedging, financing and brokerage activities. The underwriters and their respective affiliates have provided, and in the future may provide, certain investment banking, commercial banking and financial advisory services to us and our affiliates, for which they have received, and in the future would receive, customary fees. Certain of the underwriters or their affiliates are agents, lenders or arrangers under the Senior Secured Credit Facilities. If the underwriters or their affiliates have a lending relationship with us, certain of those underwriters or their affiliates routinely hedge, certain of those underwriters or their affiliates are likely to hedge and certain others of those underwriters or their affiliates may hedge their credit exposure to us consistent with their customary risk management policies. Typically, these underwriters and their affiliates would hedge such exposure by entering into transactions that consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offering hereby. Any such short credit default swap or positions could adversely affect future trading prices of the notes offered hereby. The underwriters and their affiliates may also make investment recommendations and/or public or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments. To the extent the underwriters or their affiliates own any of the 6.625% Notes they may receive a portion of the net proceeds of this offering. U.S. Bancorp Investments, Inc., one of the underwriters, is an affiliate of the trustee. One of Holdings' directors is an officer of the parent of Huntington Securities, Inc.

Settlement

        We expect that delivery of the notes will be made to investors on or about June 12, 2020, which will be the third business day following the date of this prospectus supplement (such settlement being referred to as "T+3"). Under Rule 15c6-1 under the Exchange Act, trades in the secondary market are required to settle in two business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade notes on the day of pricing will be required, by virtue of the fact that the notes initially settle in T+3, to specify an alternate settlement arrangement at the time of any such trade to prevent a failed settlement. Purchasers of the notes who wish to trade the notes prior to their date of delivery hereunder should consult their advisors.

Offering Restrictions

        The notes are offered for sale in the United States and in jurisdictions outside the United States, subject to applicable law.

European Economic Area and the United Kingdom

        The notes are not intended to be offered, sold or otherwise made available to and should not be offered, sold or otherwise made available to any retail investor in the European Economic Area ("EEA") or in the United Kingdom ("UK").

RISK FACTORS

        Your investment in the securities involves certain risks. In consultation with your own financial and legal advisers, you should carefully consider whether an investment in the securities is suitable for you. The securities are not an appropriate investment for you if you do not understand the terms of the securities or financial matters generally. Risks relating to the securities will be set forth in the relevant prospectus supplement for the offering of such securities. In addition, certain factors that may adversely affect the business of AAM Inc. (as defined below) or Holdings (as defined below) are discussed in our periodic reports referred to in "Where You Can Find More Information," below. For example, Holdings' Annual Report on Form 10-K for the fiscal year ended December 31, 2019, contains a discussion of significant risks that could be relevant to an investment in the securities. You should not purchase the securities described in this prospectus unless you understand and know you can bear all of the investment risks involved.

WHERE YOU CAN FIND MORE INFORMATION

        We are required to comply with the reporting requirements of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and, in accordance with those requirements, we file combined reports, proxy statements and other information with the Securities and Exchange Commission (the "SEC"). Unless the context otherwise requires, the terms "the Company," "we," "us", "our" and "AAM" refer to collectively (i) American Axle & Manufacturing, Inc., or AAM Inc., a Delaware corporation, and its direct and indirect subsidiaries, (ii) American Axle & Manufacturing Holdings, Inc., or Holdings, a Delaware corporation, and the direct parent corporation of AAM Inc. and (iii) Metaldyne Performance Group Inc., or MPG, a Delaware corporation and a wholly owned subsidiary of Holdings and its direct and indirect subsidiaries. Holdings has no material operations or assets other than its ownership of 100% of the issued and outstanding common stock of AAM Inc. and MPG.

        You can call the SEC's toll-free number at 1-800-SEC-0330 for further information. The SEC maintains a website at www.sec.gov that contains reports, proxy and information statements and other information regarding companies like ours that file with the SEC electronically. The documents can be found by searching the EDGAR archives at the SEC's website. Our SEC filings and other information about us may also be obtained from our website at www.aam.com, although information on our website does not constitute a part of this prospectus. Material that we have filed may also be inspected at the library of the New York Stock Exchange, 20 Broad Street, New York, New York 10005.

        The SEC allows us to "incorporate by reference" the information we file with them, which means that we can disclose important information to you by referring you to those documents that are considered part of this prospectus. Later information that we file will automatically update and supersede this information. We incorporate by reference the documents listed below and any future filings we make with the SEC under Section 13(a), 13(c), 14 or 15(d) of the Exchange Act (other than information furnished under Items 2.02 or 7.01 of Form 8-K) (i) after the date of the filing of this registration statement and prior to effectiveness and (ii) until the offering of the particular securities covered by a prospectus supplement or term sheet has been completed. This prospectus is part of a registration statement filed with the SEC.

PROSPECTUS

        This prospectus is part of a registration statement that we filed with the SEC utilizing a "shelf" registration process. Under this shelf process, any combination of the following securities may be sold in one or more offerings:

        The terms of the securities will be determined at the time of offering.

        We will refer to the debt securities, debt warrants, common stock warrants, warrant shares, the guarantees of the debt securities, common stock and preferred stock, or any combination of those securities, proposed to be sold under this prospectus and the applicable prospectus supplement or term sheet as the "offered securities." The offered securities, together with any debt securities, common stock and preferred stock issuable upon exercise of debt warrants, common stock warrants, warrant shares or conversion or exchange of other offered securities, as applicable, will be referred to as the "securities."

        You should rely only on the information contained or incorporated by reference in this prospectus or prospectus supplement. We have not authorized any other person to provide you with different information. If anyone provides you with different or inconsistent information, you should not rely on it. We are not making an offer to sell these securities in any jurisdiction where the offer or sale is not permitted. You should assume that the information appearing in this prospectus, prospectus supplement, or any documents incorporated by reference is accurate only as of the date on the front cover of the applicable document. Our business, financial condition, results of operations and prospects may have changed since then.


PROSPECTUS SUPPLEMENT OR TERM SHEET

        This prospectus provides you with a general description of the debt securities, warrants to purchase debt securities, common stock warrants, warrant shares, common stock and preferred stock we may offer. Each time we sell securities, we will provide a prospectus supplement or term sheet that will contain specific information about the terms of that offering and whether securities are being offered by us, a selling security holder or both. The prospectus supplement or term sheet to be attached to the front of this prospectus will describe: the terms of the securities offered, any initial public offering price, the price paid to us for the securities, the net proceeds to us, the manner of distribution and any underwriting compensation and the other specific material terms related to the offering of these securities. The prospectus supplement or term sheet may also add to, update or change information contained in this prospectus, and accordingly, to the extent inconsistent, information in this prospectus is superseded by the information in the prospectus supplement or term sheet. You should read both this prospectus and any prospectus supplement or term sheet together with the additional information described under the heading "Where You Can Find More Information."

FORWARD-LOOKING STATEMENTS

        Certain statements contained in this prospectus, or any accompanying prospectus supplement and the documents incorporated herein or therein by reference are forward-looking in nature, such as statements concerning our expectations, beliefs, plans, objectives, goals, strategies, and future events or performance. Such statements are "forward-looking" statements within the meaning of the Private Securities Litigation Reform Act of 1995 and relate to trends and events that may affect our future financial position and operating results. The terms such as "will," "may," "could," "would," "plan," "believe," "expect," "anticipate," "intend," "project," "target," and similar words or expressions, as well as statements in future tense, are intended to identify forward-looking statements.

        Forward-looking statements should not be read as a guarantee of future performance or results, and will not necessarily be accurate indications of the times at, or by, which such performance or results will be achieved. Forward-looking statements are based on information available at the time those statements are made and/or management's good faith belief as of that time with respect to future events and are subject to risks and may differ materially from those expressed in or suggested by the forward-looking statements. Important factors that could cause such differences include, but are not limited to:

Table of Contents

        It is not possible to foresee or identify all such factors and we make no commitment to update any forward-looking statement or to disclose any facts, events or circumstances after the date hereof that may affect the accuracy of any forward-looking statement.


DESCRIPTION OF DEBT SECURITIES

        We may issue debt securities in one or more distinct series. This section summarizes the material terms of the debt securities that are common to all series. Most of the financial terms and other specific material terms of any series of debt securities that we offer will be described in a prospectus supplement or term sheet to be attached to the front of this prospectus. Furthermore, since the terms of specific debt securities may differ from the general information we have provided below, you should rely on information in the prospectus supplement or term sheet that contradicts different information below.

        As required by federal law for all debt securities of companies that are publicly offered, the debt securities are governed by a document called an "indenture." An indenture is a contract between us and a financial institution acting as trustee on your behalf. Unless otherwise indicated in a prospectus supplement, the trustee will be U.S. Bank National Association. The trustee has two main roles. First,

5


Table of Contents

the trustee can enforce your rights against us if we default. There are some limitations on the extent to which the trustee acts on your behalf, described in the sixth paragraph under "Events of Default." Second, the trustee performs certain administrative duties for us.

        The term "trustee" refers to the senior trustee or the subordinated trustee, as appropriate. We will refer to the indenture that governs the debt securities, as amended from time to time, as the "Indenture." The Indenture is subject to and governed by the Trust Indenture Act of 1939, as amended (the "TIA").

        The following summary does not purport to be complete, and is subject to, and is qualified in its entirety by reference to, all of the provisions of the debt securities and the Indenture. We urge you to read the Indenture and the form of the debt securities, which you may obtain from us upon request. As used in this description, all references to "AAM Inc.," "our company," the "issuer," "we," "us" or "our" mean American Axle & Manufacturing, Inc., excluding, unless otherwise expressly stated or the context otherwise requires, its subsidiaries, including those acting as Subsidiary Guarantors (as defined below), and all references to "Holdings" mean American Axle & Manufacturing Holdings, Inc., our parent corporation, excluding, unless otherwise expressly stated or the context otherwise requires, its subsidiaries. Holdings has no material operations or assets other than its ownership of 100% of the issued and outstanding common stock of American Axle & Manufacturing, Inc., and Metaldyne Performance Group Inc. ("MPG"). The Subsidiary Guarantors are MPG and certain of AAM Inc.'s and MPG's current and future subsidiaries ("Subsidiary Guarantors").

General

        The debt securities will be AAM Inc.'s obligations which may be secured or unsecured. The senior unsecured securities will rank equally with all of our other unsecured and unsubordinated indebtedness and will be guaranteed by Holdings and/or any Subsidiary Guarantors, if applicable. The Holdings guarantee and any Subsidiary guarantees will rank equally with all of their other unsecured and unsubordinated indebtedness. Terms of secured debt securities and the related Holdings guarantee and any Subsidiary guarantees will be more fully described in a prospectus supplement. The subordinated securities will be subordinated in right of payment to the prior payment in full of AAM Inc.'s senior indebtedness as more fully described in a prospectus supplement or term sheet. The subordinated debt securities will be guaranteed on a subordinated basis by Holdings, and, if applicable, the Subsidiary Guarantors, as more fully described in a prospectus supplement or term sheet.

        The Indenture provides that any debt securities proposed to be sold under this prospectus and the attached prospectus supplement or term sheet, including the guarantee by Holdings and any Subsidiary guarantees ("offered debt securities") and any debt securities issuable upon the exercise of debt warrants or upon conversion or exchange of other offered securities ("underlying debt securities"), as well as other unsecured debt securities, may be issued under the Indenture in one or more series.

        You should read the prospectus supplement or term sheet for the material terms of the offered debt securities and any underlying debt securities, including the following:

6


Table of Contents

7


Table of Contents

        For purposes of this prospectus, any reference to the payment of principal or premium or interest, if any, on the debt securities will include additional amounts if required by the terms of the debt securities.

        The Indenture does not limit the amount of debt securities that may be issued thereunder from time to time. Debt securities issued under the Indenture, when a single trustee is acting for all debt securities issued under the Indenture, are called the "indenture securities." The Indenture also provides that there may be more than one trustee thereunder, each with respect to one or more different series of indenture securities. See "Resignation of Trustee" below. At a time when two or more trustees are acting under the Indenture, each with respect to only certain series, the term "indenture securities" means the one or more series of debt securities with respect to which each respective trustee is acting. In the event that there is more than one trustee under the Indenture, the powers and trust obligations of each trustee described in this prospectus will extend only to the one or more series of indenture securities for which it is trustee. If two or more trustees are acting under the Indenture, then the indenture securities for which each trustee is acting would be treated as if issued under separate indentures.

        The Indenture does not contain any provisions that give you protection in the event we issue a large amount of debt or we are acquired by another entity.

        We refer you to the prospectus supplement or term sheet for information with respect to any deletions from, modifications of or additions to the Events of Default or our covenants that are described below, including any addition of a covenant or other provision providing event risk or similar protection.

        We have the ability to issue indenture securities with terms different from those of indenture securities previously issued and, without the consent of the holders thereof, to reopen a previous issue of a series of indenture securities and issue additional indenture securities of that series unless the reopening was restricted when that series was created.

        Unless otherwise specified in the applicable prospectus supplement or term sheet, the debt securities will be denominated in U.S. dollars and all payments on the debt securities will be made in U.S. dollars.

        Payment of the purchase price of the debt securities must be made in immediately available funds.

        As used in this prospectus, "Business Day" means any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which commercial banks are authorized or required by law, regulation or executive order to close in The City of New York; provided, however, that, with respect to foreign currency debt securities, the day is also not a day on which commercial banks are authorized or required by law, regulation or executive order to close in the Principal Financial Center (as defined below) of the country issuing the specified currency (or, if the specified currency is the euro, the day is also a day on which the Trans-European Automated Real Time Gross Settlement Express Transfer ("TARGET") System is operating, which we refer to as a "TARGET Business Day"); and provided further that, with respect to debt securities as to which LIBOR is an applicable interest rate basis, the day is also a London Business Day.

        "London Business Day" means a day on which commercial banks are open for business (including dealings in the designated LIBOR Currency) in London.

8


Table of Contents

        "Principal Financial Center" means (i) the capital city of the country issuing the specified currency or (ii) the capital city of the country to which the designated LIBOR Currency relates, as applicable, except that the term "Principal Financial Center" means the following cities in the case of the following currencies:

Currency   Principal Financial Center
U.S. dollars   The City of New York
Australian dollars   Sydney
Canadian dollars   Toronto
New Zealand dollars   Auckland
South African rand   Johannesburg
Swiss francs   Zurich

and in the event the LIBOR Currency is the euro, the "Principal Financial Center" is London.

        The authorized denominations of debt securities denominated in U.S. dollars will be $2,000 and integral multiples of $1,000 thereafter. The authorized denominations of foreign currency debt securities will be set forth in the applicable prospectus supplement or term sheet.

Optional Redemption, Repayment and Repurchase

        If specified in a prospectus supplement or term sheet, we may redeem the debt securities at our option, in whole at any time or in part from time to time, at a redemption price as set forth in the applicable prospectus supplement or term sheet.

        We will mail notice of any redemption at least 30 days, but not more than 60 days, before the date of redemption to each holder of the debt securities to be redeemed. If less than all of the debt securities are to be redeemed at any time, the trustee will select debt securities to be redeemed on a pro rata basis or by any other method the trustee deems fair and appropriate. Unless we default in payment of the redemption price, on and after the date of redemption, interest will cease to accrue on the debt securities or portions thereof called for redemption.

        Regardless of anything in this prospectus to the contrary, if a debt security is an OID Note (as defined below) (other than an Indexed Note), the amount payable in the event of redemption or repayment prior to its stated maturity will be the amortized face amount on the redemption or repayment date, as the case may be. The amortized face amount of an OID Note will be equal to (i) the issue price specified in the applicable prospectus supplement or term sheet plus (ii) that portion of the difference between the issue price and the principal amount of the OID Note that has accrued at the yield to maturity described in the prospectus supplement or term sheet (computed in accordance with generally accepted U.S. bond yield computation principles) by the redemption or repayment date. However, in no case will the amortized face amount of an OID Note exceed its principal amount.

        We may at any time purchase debt securities at any price in the open market or otherwise. We may hold, resell or surrender for cancellation any debt securities that we purchase.

Conversion and Exchange

        If any debt securities are convertible into or exchangeable for other securities, the prospectus supplement or term sheet will explain the terms and conditions of the conversion or exchange, including the conversion price or exchange ratio (or the calculation method), the conversion or exchange period (or how the period will be determined), if conversion or exchange will be mandatory or at the option of the holder or us, provisions for adjusting the conversion price or the exchange ratio and provisions affecting conversion or exchange in the event of the redemption of the underlying debt securities. These terms may also include provisions under which the number or amount of other

9


Table of Contents

securities to be received by the holders of the debt securities upon conversion or exchange would be calculated according to the market price of the other securities as of a time stated in the prospectus supplement or term sheet.

Issuance of Securities in Registered Form

        We may issue the debt securities in registered form, in which case we will issue them in book-entry form only. Debt securities issued in book-entry form will be represented by global securities. We also will have the option of issuing debt securities in non-registered form as bearer securities if we issue the securities outside the United States to non-U.S. persons. In that case, the prospectus supplement or term sheet will set forth the mechanics for holding the bearer securities, including the procedures for receiving payments, for exchanging the bearer securities for registered securities of the same series, and for receiving notices. The prospectus supplement or term sheet will also describe the requirements with respect to our maintenance of offices or agencies outside the United States and the applicable U.S. federal tax law requirements.

        Book-Entry Holders.    We will issue registered debt securities in book-entry form only, unless we specify otherwise in the applicable prospectus supplement or term sheet. This means debt securities will be represented by one or more global securities registered in the name of a depositary that will hold them on behalf of financial institutions that participate in the depositary's book-entry system. These participating institutions, in turn, hold beneficial interests in the debt securities held by the depositary or its nominee. These institutions may hold these interests on behalf of themselves or customers.

        Under the Indenture, only the person in whose name a debt security is registered is recognized as the holder of that debt security. Consequently, for debt securities issued in book-entry form, we will recognize only the depositary as the holder of the debt securities and we will make all payments on the debt securities to the depositary. The depositary will then pass along the payments it receives to its participants, which, in turn, will pass the payments along to their customers who are the beneficial owners. The depositary and its participants do so under agreements they have made with one another or with their customers; they are not obligated to do so under the terms of the debt securities.

        As a result, investors will not own debt securities directly. Instead, they will own beneficial interests in a global security, through a bank, broker or other financial institution that participates in the depositary's book-entry system or holds an interest through a participant. As long as the debt securities are represented by one or more global securities, investors will be indirect holders, and not holders of the debt securities.

        Street Name Holders.    In the future, we may issue debt securities in certificated form or terminate a global security. In these cases, investors may choose to hold their debt securities in their own names or in "street name." Debt securities held in street name are registered in the name of a bank, broker or other financial institution chosen by the investor, and the investor would hold a beneficial interest in those debt securities through the account he or she maintains at that institution.

        For debt securities held in street name, we will recognize only the intermediary banks, brokers and other financial institutions in whose names the debt securities are registered as the holders of those debt securities and we will make all payments on those debt securities to them. These institutions will pass along the payments they receive to their customers who are the beneficial owners, but only because they agree to do so in their customer agreements or because they are legally required to do so. Investors who hold debt securities in street name will be indirect holders, and not holders, of the debt securities.

        Legal Holders.    Our obligations, as well as the obligations of the applicable trustee and those of any third parties employed by us or the applicable trustee, run only to the legal holders of the debt securities. We do not have obligations to investors who hold beneficial interests in global securities, in

10


Table of Contents

street name or by any other indirect means. This will be the case whether an investor chooses to be an indirect holder of a debt security or has no choice because we are issuing the debt securities only in book-entry form.

        For example, once we make a payment or give a notice to the holder, we have no further responsibility for the payment or notice even if that holder is required, under agreements with depositary participants or customers or by law, to pass it along to the indirect holders but does not do so. Similarly, if we want to obtain the approval of the holders for any purpose (for example, to amend the Indenture or to relieve us of the consequences of a default or of our obligation to comply with a particular provision of the Indenture), we would seek the approval only from the holders, and not the indirect holders, of the debt securities. Whether and how the holders contact the indirect holders is up to the holders.

        When we refer to you, we mean those who invest in the debt securities being offered by this prospectus, the prospectus supplement or term sheet whether they are the holders or only indirect holders of those debt securities. When we refer to your debt securities, we mean the debt securities in which you hold a direct or indirect interest.

        Special Considerations for Indirect Holders.    If you hold debt securities through a bank, broker or other financial institution, either in book-entry form or in street name, we urge you to check with that institution to find out:

Interest and Interest Rates

        Each debt security will begin to accrue interest from the date it is originally issued. The related prospectus supplement or term sheet will specify each debt security as a "Fixed Rate Note," a "Floating Rate Note," an "Amortizing Note" or an "Indexed Note" and describe the method of determining the interest rate, including any spread and/or spread multiplier. For an Indexed Note, the related prospectus supplement or term sheet also will describe the method for the calculation and payment of principal and interest. The prospectus supplement or term sheet for a Floating Rate Note or Indexed Note may also specify a maximum and a minimum interest rate.

        A debt security may be issued as a Fixed Rate Note or a Floating Rate Note or as a Note that combines fixed and floating rate terms.

        Interest rates offered with respect to debt securities may differ depending upon, among other things, the aggregate principal amount of debt securities purchased in any single transaction. Debt securities with similar variable terms but different interest rates, as well as debt securities with different variable terms, may be offered concurrently to different investors. Interest rates or formulas and other

11


Table of Contents

terms of debt securities are subject to change from time to time, but no such change will affect any debt security already issued or as to which an offer to purchase has been accepted.

        Interest on the debt securities denominated in U.S. dollars will be paid by check mailed on an Interest Payment Date (as defined below) other than a Maturity Date (as defined below) to the persons entitled thereto to the addresses of such holders as they appear in the security register or, at our option, by wire transfer to a bank account maintained by the holder. The principal of, premium, if any, and interest on debt securities denominated in U.S. dollars, together with interest accrued and unpaid thereon, due on the Maturity Date will be paid in immediately available funds upon surrender of such debt securities at the corporate trust office of the trustee in The City of New York, or, at our option, by wire transfer of immediately available funds to an account with a bank designated at least 15 calendar days prior to the Maturity Date by the applicable registered holder, provided the particular bank has appropriate facilities to receive these payments and the particular debt security is presented and surrendered at the office or agency maintained by us for this purpose in the Borough of Manhattan, The City of New York, in time for the trustee to make these payments in accordance with its normal procedures.

        The prospectus supplement or term sheet for Fixed Rate Notes will describe a fixed interest rate payable semiannually in arrears on the dates specified in such term sheet or prospectus supplement (each, with respect to Fixed Rate Notes, an "Interest Payment Date"). Interest on Fixed Rate Notes will be computed on the basis of a 360-day year of twelve 30-day months. If the stated maturity date, any redemption date or any repayment date (together referred to as the "Maturity Date") or an Interest Payment Date for any Fixed Rate Note is not a Business Day, principal of, premium, if any, and interest on that Note will be paid on the next Business Day, and no interest will accrue from and after the Maturity Date or Interest Payment Date. Interest on Fixed Rate Notes will be paid to holders of record as of each Regular Record Date. A "Regular Record Date" will be the fifteenth day (whether or not a Business Day) next preceding the applicable Interest Payment Date.

        Each interest payment on a Fixed Rate Note will include interest accrued from, and including, the issue date or the last Interest Payment Date, as the case may be, to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be.

        We may issue original issue discount debt securities (including zero coupon debt securities) ("OID Notes"), which are debt securities issued at a discount from the principal amount payable on the Maturity Date. There may not be any periodic interest payments on OID Notes. For OID Notes, interest normally accrues during the life of the OID Note and is paid on the Maturity Date. Upon a redemption, repayment or acceleration of the maturity of an OID Note, the amount payable will be determined as set forth under "—Optional Redemption, Repayment and Repurchase." This amount normally is less than the amount payable on the stated maturity date.

        We may issue amortizing debt securities, which are Fixed Rate Notes for which combined principal and interest payments are made in installments over the life of each debt securities ("Amortizing Notes"). Payments on Amortizing Notes are applied first to interest due and then to the reduction of the unpaid principal amount. The related prospectus supplement or term sheet for an Amortizing Note will include a table setting forth repayment information.

        Each Floating Rate Note will have an interest rate basis or formula. That basis or formula may be based on:

        The prospectus supplement or term sheet will also indicate any spread and/or spread multiplier, which would be applied to the interest rate formula to determine the interest rate. Any Floating Rate Note may have a maximum or minimum interest rate limitation. In addition to any maximum interest rate limitation, the interest rate on the Floating Rate Notes will in no event be higher than the maximum rate permitted by New York law, as the same may be modified by United States law for general application. Floating Rate Notes will have a minimum interest rate of 0.0%

        We will appoint a calculation agent to calculate interest rates on the Floating Rate Notes. Unless we identify a different party in the prospectus supplement or term sheet, the paying agent will be the calculation agent for each Note.

        Unless otherwise specified in a prospectus supplement or term sheet, the "Calculation Date," if applicable, relating to an Interest Determination Date (as described below under "—Date Interest Rate is Determined") will be the earlier of (i) the tenth calendar day after such Interest Determination Date or, if such day is not a Business Day, the next succeeding Business Day, or (ii) the Business Day immediately preceding the relevant Interest Payment Date or the Maturity Date, as the case may be.

        Upon the request of the beneficial holder of any Floating Rate Note, the calculation agent will provide the interest rate then in effect and, if different, when available, the interest rate that will become effective on the next Interest Reset Date for the Floating Rate Note.

        Change of Interest Rate.    The interest rate on each Floating Rate Note may be reset daily, weekly, monthly, quarterly, semiannually, annually or on some other specified basis (each, an "Interest Reset Date"). The Interest Reset Date will be:

13


Table of Contents

        The related prospectus supplement or term sheet will describe the initial interest rate or interest rate formula on each Note. That rate is effective until the following Interest Reset Date. Thereafter, the interest rate will be the rate determined on each Interest Determination Date. Each time a new interest rate is determined, it becomes effective on the following Interest Reset Date. If any Interest Reset Date is not a Business Day, then the Interest Reset Date is postponed to the next Business Day, except, in the case of LIBOR and EURIBOR Notes, if the next Business Day is in the next calendar month, the Interest Reset Date is the immediately preceding Business Day.

        Date Interest Rate Is Determined.    The Interest Determination Date for all CD and CMT Rate Notes is the second Business Day before the Interest Reset Date and for all LIBOR Notes will be the second London Business Day immediately preceding the applicable Interest Reset Date (unless the LIBOR Currency is Sterling, in which case the Interest Determination Date will be the Interest Reset Date).

        The Interest Determination Date for Treasury Rate Notes will be the day of the week in which the Interest Reset Date falls on which Treasury bills of the Index Maturity are normally auctioned. Treasury bills are usually sold at auction on Monday of each week, unless that day is a legal holiday, in which case the auction is usually held on Tuesday. Sometimes, the auction is held on the preceding Friday. If an auction is held on the preceding Friday, that day will be the Interest Determination Date relating to the Interest Reset Date occurring in the next week.

        The Interest Determination Date for all Commercial Paper, Federal Funds and Prime Rate Notes will be the first Business Day preceding the Interest Reset Date.

        The Interest Determination Date for EURIBOR Notes will be the second TARGET Business Day immediately preceding the applicable Interest Reset Date.

        The Interest Determination Date for an Eleventh District Cost of Funds Rate Note is the last Business Day of the month immediately preceding the applicable Interest Reset Date in which the Federal Home Loan Bank of San Francisco published the applicable rate.

        The Interest Determination Date relating to a Floating Rate Note with an interest rate that is determined by reference to two or more interest rate bases will be the most recent Business Day which is at least two Business Days before the applicable Interest Reset Date for each interest rate for the applicable Floating Rate Note on which each interest rate basis is determinable.

        Payment of Interest.    Interest is paid as follows:

14


Table of Contents

        Each interest payment on a Floating Rate Note will include interest accrued from, and including, the issue date or the last Interest Payment Date, as the case may be, to but excluding the applicable Interest Payment Date or the Maturity Date, as the case may be.

        Interest on a Floating Rate Note will be payable beginning on the first Interest Payment Date after its issue date to holders of record at the close of business on each Regular Record Date, which is the fifteenth day (whether or not a Business Day) next preceding the applicable Interest Payment Date, unless the issue date falls after a Regular Record Date and on or prior to the related Interest Payment Date, in which case payment will be made to holders of record at the close of business on the Regular Record Date next preceding the second Interest Payment Date following the issue date. If an Interest Payment Date (but not the Maturity Date) is not a Business Day, then the Interest Payment Date will be postponed to the next Business Day, except in the case of LIBOR and EURIBOR Notes, if the next Business Day is in the next calendar month, the Interest Payment Date will be the immediately preceding Business Day. If the Maturity Date of any Floating Rate Note is not a Business Day, principal of, premium, if any, and interest on that Note will be paid on the next Business Day, and no interest will accrue from and after the Maturity Date.

        Accrued interest on a Floating Rate Note is calculated by multiplying the principal amount of a Note by an accrued interest factor. The accrued interest factor is the sum of the interest factors calculated for each day in the period for which accrued interest is being calculated. The interest factor for each day is computed by dividing the interest rate in effect on that day by (1) the actual number of days in the year, in the case of Treasury Rate Notes or CMT Rate Notes, or (2) 360, in the case of other Floating Rate Notes. The interest factor for Floating Rate Notes for which the interest rate is calculated with reference to two or more interest rate bases will be calculated in each period in the same manner as if only one of the applicable interest rate bases applied. All percentages resulting from any calculation are rounded to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upward. For example, 9.876545% (or .09876545) will be rounded to 9.87655% (or .0987655). Dollar amounts used in the calculation are rounded to the nearest cent (with one-half cent being rounded upward).

        CD Rate Notes.    The "CD Rate" for any Interest Determination Date is the rate on that date for negotiable U.S. dollar certificates of deposit having the Index Maturity described in the related prospectus supplement or term sheet, as published in H.15 prior to 3:00 P.M., New York City time, on the Calculation Date, for that Interest Determination Date under the heading "CDs (secondary market)." The "Index Maturity" is the period to maturity of the instrument or obligation with respect to which the related interest rate basis or formula will be calculated.

Indexed Notes

        We may issue debt securities for which the amount of interest or principal that you will receive will not be known on your date of purchase. Interest or principal payments for these types of debt securities, which we call "Indexed Notes," are determined by reference to securities, financial or non-financial indices, currencies, commodities, interest rates, or a composite or baskets of any or all of the above. Examples of indexed items that may be used include a published stock index, the common stock price of a publicly traded company, the value of the U.S. dollar versus the Japanese yen, or the price of a barrel of West Texas intermediate crude oil.

        If you purchase an Indexed Note, you may receive a principal amount at maturity that is greater than or less than the Note's face amount, and an interest rate that is greater than or less than the interest rate that you would have earned if you had instead purchased a conventional debt security issued by us at the same time with the same maturity. The amount of interest and principal that you will receive will depend on the structure of the Indexed Note and the level of the specified indexed item throughout the term of the Indexed Note and at maturity. Specific information pertaining to the method of determining the interest payments and the principal amount will be described in the prospectus supplement or term sheet, as well as additional risk factors unique to the Indexed Note,

certain historical information for the specified indexed item and certain additional United States federal tax considerations.

Renewable Notes

        We may issue Renewable Notes ("Renewable Notes") which are debt securities that will automatically renew at their stated maturity date unless the holder of a Renewable Note elects to terminate the automatic extension feature by giving notice in the manner described in the related prospectus supplement or term sheet.

        The holder of a Renewable Note must give notice of termination at least 15 but not more than 30 days prior to a Renewal Date. The holder of a Renewable Note may terminate the automatic extension for less than all of its Renewable Notes only if the terms of the Renewable Note specifically permit partial termination. An election to terminate the automatic extension of any portion of the Renewable Note is not revocable and will be binding on the holder of the Renewable Note. If the holder elects to terminate the automatic extension of the maturity of the Note, the holder will become entitled to the principal and interest accrued up to the Renewal Date. The related prospectus supplement or term sheet will identify a stated maturity date beyond which the Maturity Date cannot be renewed.

        If a Renewable Note is represented by a Global Security, DTC or its nominee will be the holder of the Note and therefore will be the only entity that can exercise a right to terminate the automatic extension of a Note. In order to ensure that DTC or its nominee will exercise a right to terminate the automatic extension provisions of a particular Renewable Note, the beneficial owner of the Note must instruct the broker or other DTC participant through which it holds an interest in the Note to notify DTC of its desire to terminate the automatic extension of the Note. Different firms have different cut-off times for accepting instructions from their customers and, accordingly, each beneficial owner should consult the broker or other participant through which it holds an interest in a Note to ascertain the cut-off time by which an instruction must be given for delivery of timely notice to DTC or its nominee.

Extendible Notes

        We may issue Notes whose stated Maturity Date may be extended at our option (an "Extendible Note") for one or more whole-year periods (each, an "Extension Period"), up to but not beyond a stated maturity date described in the related prospectus supplement or term sheet (but not to exceed 30 years from the date of issue).

        We may exercise our option to extend the Extendible Note by notifying the applicable trustee (or any duly appointed paying agent) at least 45 but not more than 60 days prior to the then effective Maturity Date. If we elect to extend the Extendible Note, the trustee (or paying agent) will mail (at least 40 days prior to the Maturity Date) to the registered holder of the Extendible Note a notice (an "Extension Notice") informing the holder of our election, the new Maturity Date and any updated terms. Upon the mailing of the Extension Notice, the maturity of that Extendible Note will be extended automatically as set forth in the Extension Notice.

        However, we may, not later than 20 days prior to the Maturity Date of an Extendible Note (or, if that date is not a Business Day, prior to the next Business Day), at our option, establish a higher interest rate, in the case of a Fixed Rate Note, or a higher spread and/or spread multiplier, in the case of a Floating Rate Note, for the Extension Period by mailing or causing the applicable trustee (or paying agent) to mail notice of such higher interest rate or higher spread and/or spread multiplier to the holder of the Note. The notice will be irrevocable.

24


Table of Contents

        If we elect to extend the maturity of an Extendible Note, the holder of the Note will have the option to instead elect repayment of the Note by us on the then effective Maturity Date. In order for an Extendible Note to be so repaid on the Maturity Date, we must receive, at least 15 days but not more than 30 days prior to the Maturity Date:

        If an Extendible Note is represented by a Global Security, DTC or its nominee will be the holder of that Note and therefore will be the only entity that can exercise a right to repayment. To ensure that DTC or its nominee timely exercises a right to repayment with respect to a particular Extendible Note, the beneficial owner of that Note must instruct the broker or other participant through which it holds an interest in the Note to notify DTC of its desire to exercise a right of repayment. Different firms have different cut-off times for accepting instructions from their customers and, accordingly, each beneficial owner should consult the broker or other participant through which it holds an interest in an Extendible Note to determine the cut-off time by which an instruction must be given for timely notice to be delivered to DTC or its nominee.

Global Securities

        What Is a Global Security?    As noted above, we usually will issue debt securities as registered securities in book-entry form only. A global security represents one or any other number of individual debt securities. Generally, all debt securities represented by the same global securities will have the same terms.

        Each debt security issued in book-entry form will be represented by a global security that we deposit with and register in the name of a financial institution or its nominee that we select. The financial institution that we select for this purpose is called the depositary. Unless we specify otherwise in the applicable prospectus supplement or term sheet, The Depository Trust Company, New York, New York, known as DTC, will be the depositary for all debt securities issued in book-entry form.

        A global security may not be transferred to or registered in the name of anyone other than the depositary or its nominee, unless special termination situations arise. We describe those situations below under "Special Situations when a Global Security Will Be Terminated." As a result of these arrangements, the depositary, or its nominee, will be the sole registered owner and holder of all debt securities represented by a global security, and investors will be permitted to own only beneficial interests in a global security. Beneficial interests must be held by means of an account with a broker, bank or other financial institution that in turn has an account with the depositary or with another institution that has an account with the depositary. Thus, an investor whose security is represented by a global security will not be a holder of the debt security, but only an indirect holder of a beneficial interest in the global security.

25


Table of Contents

        Special Considerations for Global Securities.    As an indirect holder, an investor's rights relating to a global security will be governed by the account rules of the investor's financial institution and of the depositary, as well as general laws relating to securities transfers. The depositary that holds the global security will be considered the holder of the debt securities represented by the global security.

        If debt securities are issued only in the form of a global security, an investor should be aware of the following:

        Special Situations When a Global Security Will Be Terminated.    In a few special situations described below, a global security will be terminated and interests in it will be exchanged for certificates in non-book-entry form (certificated securities). After that exchange, the choice of whether to hold the certificated debt securities directly or in street name will be up to the investor. Investors must consult their own banks or brokers to find out how to have their interests in a global security transferred on termination to their own names, so that they will be holders. We have described the rights of holders and street name investors under "Issuance of Securities in Registered Form" above.

26


Table of Contents

        The special situations for termination of a global security are as follows:

        The prospectus supplement or term sheet may list situations for terminating a global security that would apply only to the particular series of debt securities covered by the prospectus supplement or term sheet. If a global security is terminated, only the depositary, and not we or the applicable trustee, is responsible for deciding the names of the institutions in whose names the debt securities represented by the global security will be registered and, therefore, who will be the holders of those debt securities.

Payment and Paying Agents

        We will pay interest to the person listed in the trustee's records as the owner of the debt security at the close of business on a particular day in advance of each due date for interest, even if that person no longer owns the debt security on the interest due date. That day, usually about two weeks in advance of the interest due date, is called the "record date." Because we will pay all the interest for an interest period to the holders on the record date, holders buying and selling debt securities must work out between themselves the appropriate purchase price. The most common manner is to adjust the sales price of the debt securities to prorate interest fairly between buyer and seller based on their respective ownership periods within the particular interest period. This prorated interest amount is called "accrued interest."

        Payments on Global Securities.    We will make payments on a global security in accordance with the applicable policies of the depositary as in effect from time to time. Under those policies, we will make payments directly to the depositary, or its nominee, and not to any indirect holders who own beneficial interests in the global security. An indirect holder's right to those payments will be governed by the rules and practices of the depositary and its participants, as described under "What Is a Global Security?".

        Payments on Certificated Securities.    We will make payments on a certificated debt security as follows. We will pay interest that is due on an interest payment date by check mailed on the interest payment date to the holder at his or her address shown on the trustee's records as of the close of business on the regular record date. We will make all payments of principal and premium, if any, by check at the office of the applicable trustee in New York, New York and/or at other offices that may be specified in the prospectus supplement or term sheet or in a notice to holders, against surrender of the debt security.

        Alternatively, if the holder asks us to do so, we will pay any amount that becomes due on the debt security by wire transfer of immediately available funds to an account at a bank in New York City, on the due date. To request payment by wire, the holder must give the applicable trustee or other paying agent appropriate transfer instructions at least 15 Business Days before the requested wire payment is due. In the case of any interest payment due on an interest payment date, the instructions must be given by the person who is the holder on the relevant regular record date. Any wire instructions, once properly given, will remain in effect unless and until new instructions are given in the manner described above.

        Payment When Offices Are Closed.    If any payment is due on a debt security on a day that is not a Business Day, we will make the payment on the next day that is a Business Day. Payments made on the

27


Table of Contents

next Business Day in this situation will be treated under the Indenture as if they were made on the original due date, except as otherwise indicated in the attached prospectus supplement or term sheet. Such payment will not result in a default under any debt security or the Indenture, and no interest will accrue on the payment amount from the original due date to the next day that is a Business Day.

Material Covenants

        Consolidation, Merger, Sale or Conveyance.    The Indenture provides that AAM Inc. or Holdings may not consolidate with or merge into any other entity or convey, transfer or lease their properties and assets substantially as an entirety to any entity, unless:

        In case of any such consolidation, merger, conveyance or transfer, the successor entity will succeed to and be substituted for AAM Inc. or Holdings, as the case may be, as obligor or guarantor on the debt securities, as the case may be, with the same effect as if it had been named in the Indenture as AAM Inc. or Holdings, as the case may be.

        Limitation on Liens.    AAM Inc. and Holdings will not, and will not permit any Restricted Subsidiary to, create, incur, issue, assume or guarantee any indebtedness for money borrowed ("Debt") secured by a Mortgage upon any Operating Property, or upon shares of capital stock or Debt issued by any Restricted Subsidiary and owned by AAM Inc. or Holdings or any Restricted Subsidiary, whether owned at the date of the Indenture or thereafter acquired, without effectively providing concurrently that the debt securities of each series then outstanding under the Indenture are secured equally and ratably with or, at our option, prior to such Debt so long as such Debt shall be so secured.

        The foregoing restriction shall not apply to, and there shall be excluded from Debt in any computation under such restriction, Debt secured by:

        Notwithstanding the restrictions described above, AAM Inc., Holdings and any Restricted Subsidiaries may create, incur, issue, assume or guarantee Debt secured by Mortgages without equally and ratably securing the debt securities of each series then outstanding if, at the time of such creation, incurrence, issuance, assumption or guarantee, after giving effect thereto and to the retirement of any Debt which is concurrently being retired, the aggregate amount of all such Debt secured by Mortgages which would otherwise be subject to such restrictions (other than any Debt secured by Mortgages permitted as described in clauses (1) through (7) of the immediately preceding paragraph) plus all Attributable Debt of AAM Inc., Holdings and the Restricted Subsidiaries in respect of Sale and Leaseback Transactions with respect to Operating Properties (with the exception of such transactions which are permitted under clauses (1) through (4) of the first sentence of the first paragraph under "—Limitation on Sale and Leaseback Transactions" below) does not exceed 10% of Consolidated Net Tangible Assets.

        "Consolidated Tangible Assets" means the aggregate of all assets of Holdings (including the value of all existing Sale and Leaseback Transactions and any assets resulting from finance leases or the capitalization of other long-term lease obligations in accordance with GAAP) appearing on the most recent available consolidated balance sheet of Holdings at their net book values, after deducting related depreciation, applicable allowances and other properly deductible items, and after deducting all goodwill, trademarks, tradenames, patents, unamortized debt discount and expenses and other like intangibles, all prepared in accordance with GAAP.

        "Consolidated Current Liabilities" means the aggregate of the current liabilities of Holdings appearing on the most recent available consolidated balance sheet of Holdings, all in accordance with GAAP. In no event shall Consolidated Current Liabilities include any obligation of Holdings or its Subsidiaries issued under a revolving credit or similar agreement if the obligation issued under such agreement matures by its terms within 12 months from the date thereof but by the terms of such agreement such obligation may be renewed or extended or the amount thereof reborrowed or refunded at the option of Holdings, our company or any Subsidiary for a term in excess of 12 months from the date of determination.

Events of Default

        An event of default is defined in the Indenture as:

31


Table of Contents

        When we refer to a "Significant Subsidiary," we mean any Subsidiary that would constitute a "significant subsidiary" within the meaning of Article 1 of Regulation S-X of the Securities Act as in effect on the date of the Indenture.

        The Indenture provides that:

        Under the Indenture, the trustee must give to the holders of debt securities notice of all uncured defaults known to it with respect to the debt securities within 90 days after such a default occurs (the term default to include the events specified above without notice or grace periods); provided that, except in the case of default in the payments of principal of or any premium on, any of the debt securities, the trustee will be protected in withholding such notice if it in good faith determines that the withholding of such notice is in the interests of the holders of the debt securities.

        No holder of any debt securities may institute any action under the Indenture unless:

        The holders of a majority in aggregate principal amount of the debt securities affected and then outstanding will have the right, subject to certain limitations, to direct the time, method and place of conducting any proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee with respect to the debt securities. The Indenture provides that, if an event of default occurs and is continuing, the trustee, in exercising its rights and powers under the Indenture, will be required to use the degree of care of a prudent man in the conduct of his own affairs. The Indenture further provides that the trustee shall not be required to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties under the Indenture unless it has reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is reasonably assured to it.

32


Table of Contents

        We must furnish to the trustee within 120 days after the end of each fiscal year a statement of our company signed by one of the officers of our company to the effect that a review of our activities during such year and our performance under the Indenture and the terms of the debt securities has been made, and, to the knowledge of the signatories based on such review, we have complied with all conditions and covenants of the Indenture or, if we are in default, specifying such default.

Modification of the Indenture

        We, the trustee and, if applicable, Holdings and any Subsidiary Guarantors, may, without the consent of the holders of the debt securities issued under the Indenture, enter into supplemental indenture for, among others, one or more of the following purposes:

        With certain exceptions, the Indenture, the Holdings guarantee, any Subsidiary guarantee or the rights of the holders of the debt securities may be modified by us and the trustee with the consent of the holders of a majority in aggregate principal amount of the debt securities then outstanding, but no such modification may be made without the consent of the holder of each outstanding debt security affected thereby that would:

Defeasance

        The following provisions will be applicable to each series of debt securities unless we state in the applicable prospectus supplement or term sheet that the provisions of covenant defeasance and full defeasance will not be applicable to that series.

33


Table of Contents

        Covenant Defeasance.    Under current United States federal tax law, we can make the deposit described below and be released from some of the restrictive covenants in the Indenture under which the particular series was issued. This is called "covenant defeasance." In that event, you would lose the protection of those restrictive covenants but would gain the protection of having money and government securities set aside in trust to repay your debt securities. If you hold subordinated securities, you also would be released from the subordination provisions described in the applicable prospectus supplement or term sheet. In order to achieve covenant defeasance, we must do the following:

        If we accomplish covenant defeasance, you can still look to us for repayment of the debt securities if there were a shortfall in the trust deposit or the trustee is prevented from making payment. In fact, if one of the remaining Events of Default occurred (such as our bankruptcy) and the debt securities became immediately due and payable, there might be a shortfall. Depending on the event causing the default, you may not be able to obtain payment of the shortfall.

        Full Defeasance.    If there is a change in United States federal tax law, as described below, we can legally release ourselves from all payment and other obligations on the debt securities of a particular series (called "full defeasance") if we put in place the following other arrangements for you to be repaid:

34


Table of Contents

        If we ever did accomplish full defeasance, as described above, you would have to rely solely on the trust deposit for repayment of the debt securities. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever became bankrupt or insolvent. If you hold subordinated securities, you would also be released from the subordination provisions described in the applicable prospectus supplement or term sheet.

Discharge of the Indenture

        We may satisfy and discharge our obligations under the Indenture by delivering to the trustee for cancellation all outstanding debt securities or by depositing with the trustee or the paying agent after the debt securities have become due and payable, whether at stated maturity, or any redemption date, or otherwise, cash sufficient to pay all of the outstanding debt securities and paying all other sums payable under the Indenture by our company.

Form, Exchange and Transfer of Certificated Registered Securities

        If registered debt securities cease to be issued in book-entry form, they will be issued:

        Holders may exchange their certificated securities for debt securities of smaller denominations or combined into fewer debt securities of larger denominations, as long as the total principal amount is not changed.

        Holders may exchange or transfer their certificated securities at the office of their trustee. We have appointed the trustee to act as our agent for registering debt securities in the names of holders transferring debt securities. We may appoint another entity to perform these functions or perform them ourselves.

        Holders will not be required to pay a service charge to transfer or exchange their certificated securities, but they may be required to pay any tax or other governmental charge associated with the transfer or exchange. The transfer or exchange will be made only if our transfer agent is satisfied with the holder's proof of legal ownership.

        If we have designated additional transfer agents for your debt security, they will be named in your prospectus supplement or term sheet. We may appoint additional transfer agents or cancel the appointment of any particular transfer agent. We may also approve a change in the office through which any transfer agent acts.

        If any certificated securities of a particular series are redeemable and we redeem less than all the debt securities of that series, we may block the transfer or exchange of those debt securities during the period beginning 15 days before the day we mail the notice of redemption and ending on the day of that mailing, in order to freeze the list of holders to prepare the mailing. We may also refuse to register transfers or exchanges of any certificated securities selected for redemption, except that we will continue to permit transfers and exchanges of the unredeemed portion of any debt security that will be partially redeemed.

35


Table of Contents

        If a registered debt security is issued in book-entry form, only the depositary will be entitled to transfer and exchange the debt security as described in this subsection, since it will be the sole holder of the debt security.

Resignation of Trustee

        The trustee may resign or be removed with respect to one or more series of indenture securities provided that a successor trustee is appointed to act with respect to these series. In the event that two or more persons are acting as trustee with respect to different series of indenture securities under the Indenture, each of the trustees will be a trustee of a trust separate and apart from the trust administered by any other trustee.

The Trustee Under the Indenture

        U.S. Bank National Association is one of a number of banks with which we maintain ordinary banking relationships and from which we may have obtained credit facilities and lines of credit.

Certain Considerations Relating to Foreign Currencies

        Debt securities denominated or payable in foreign currencies may entail significant risks. These risks include the possibility of significant fluctuations in the foreign currency markets, the imposition or modification of foreign exchange controls and potential illiquidity in the secondary market. These risks will vary depending upon the currency or currencies involved and will be more fully described in the applicable prospectus supplement or term sheet.


DESCRIPTION OF GUARANTEES

The Guarantees

        This section summarizes some of the terms of the guarantees by Holdings and/or any relevant Subsidiary Guarantor. Most of the financial terms and other specific material terms of any guarantees that we offer will be described in a prospectus supplement or term sheet to be attached to the front of this prospectus. Furthermore, since the terms of specific guarantees may differ from the general information we have provided below, you should rely on information in the prospectus supplement or term sheet that contradicts different information below.

        Each guarantee by Holdings and/or any Subsidiary Guarantors may:

        The obligations of each Subsidiary Guarantor under its guarantee will be limited as necessary to prevent that guarantee from constituting a fraudulent conveyance or fraudulent transfer under applicable law.

        Not all of our subsidiaries will guarantee the debt securities. In the event of a bankruptcy, liquidation or reorganization of any of these non-guarantor subsidiaries, these non-guarantor

36


Table of Contents

subsidiaries will pay holders of their debts and their trade creditors before they will be able to distribute any of their assets to us.

        Each guarantee by a Subsidiary Guarantor will provide by its terms that it will be automatically and unconditionally released and discharged in accordance with its terms as more fully described in the applicable prospectus supplement or term sheet.


DESCRIPTION OF DEBT WARRANTS

        We may issue (either separately or together with other offered securities) debt warrants to purchase underlying debt securities issued by us ("offered debt warrants"). We will issue the debt warrants under warrant agreements (each a "debt warrant agreement") to be entered into between us and a bank or trust company, as warrant agent (the "debt warrant agent"), identified in the prospectus supplement or term sheet.

        Because this section is a summary, it does not describe every aspect of the debt warrants and the debt warrant agreement. We urge you to read the debt warrant agreement because it, and not this description, defines your rights as a holder of debt warrants. We will file the form of debt warrant agreement with the SEC. See "Where You Can Find More Information" for information on how to obtain a copy of the debt warrant agreement.

General

        You should read the prospectus supplement or term sheet for the material terms of the offered debt warrants, including the following:

        The prospectus supplement or term sheet will also contain a discussion of the United States federal income tax considerations relevant to the offering.

        Debt warrant certificates will be exchangeable for new debt warrant certificates of different denominations. No service charge will be imposed for any permitted transfer or exchange of debt warrant certificates, but we may require payment of any tax or other governmental charge payable in connection therewith. Debt warrants may be exercised and exchanged and debt warrants in registered

37


Table of Contents

form may be presented for registration of transfer at the corporate trust office of the debt warrant agent or any other office indicated in the prospectus supplement or term sheet.

Exercise of Debt Warrants

        Each offered debt warrant will entitle the holder thereof to purchase the amount of underlying debt securities at the exercise price set forth in, or calculable from, the prospectus supplement or term sheet relating to the offered debt warrants. After the close of business on the expiration date, unexercised debt warrants will be void.

        Debt warrants may be exercised by payment to the debt warrant agent of the applicable exercise price and by delivery to the debt warrant agent of the related debt warrant certificate, properly completed. Debt warrants will be deemed to have been exercised upon receipt of the exercise price and the debt warrant certificate or certificates.

        Upon receipt of this payment and the properly completed debt warrant certificates, we will, as soon as practicable, deliver the amount of underlying debt securities purchased upon exercise.

        If fewer than all of the debt warrants represented by any debt warrant certificate are exercised, a new debt warrant certificate will be issued for the unexercised debt warrants. The holder of a debt warrant will be required to pay any tax or other governmental charge that may be imposed in connection with any transfer involved in the issuance of underlying debt securities purchased upon exercise.

Modifications

        There are three types of changes we can make to a debt warrant agreement and the debt warrants issued thereunder.

        Changes Requiring Your Approval.    First, there are changes that cannot be made to your debt warrants without your specific approval. Those types of changes include modifications and amendments that:

        Changes Not Requiring Approval.    The second type of change does not require any vote by holders of the debt warrants. This type of change is limited to clarifications and other changes that would not materially adversely affect the interests of holders of the debt warrants.

        Changes Requiring a Majority Vote.    Any other change to the debt warrant agreement and the debt warrants requires a vote in favor by holders of a majority in number of the then outstanding unexercised debt warrants affected thereby. Most changes fall into this category.

No Rights as Holders of Underlying Debt Securities

        Before the warrants are exercised, holders of the debt warrants are not entitled to payments of principal, premium or interest, if any, on the related underlying debt securities or to exercise any rights whatsoever as holders of the underlying debt securities.

38

DESCRIPTION OF WARRANTS TO PURCHASE COMMON STOCK

        Holdings may issue (either separately or together with other offered securities) warrants to purchase common stock of Holdings ("common warrants"). We will issue the common warrants under warrant agreements (each, a "common warrant agreement") to be entered into between Holdings and a bank or trust company, as warrant agent (the "common warrant agent"), identified in the prospectus supplement or term sheet.

        Because this section is a summary, it does not describe every aspect of the common warrants and common warrant agreement.

General

        You should read the prospectus supplement or term sheet for the material terms of the offered common warrants, including the following:

        The prospectus supplement or term sheet will also contain a discussion of the United States federal income tax considerations relevant to the offering.

        Certificates representing common warrants will be exchangeable for new common warrant certificates of different denominations. We will not impose a service charge for any permitted transfer or exchange of common warrant certificates, but we may require payment of any tax or other governmental charge payable in connection therewith. Common warrants may be exercised at the corporate trust office of the common warrant agent or any other office indicated in the prospectus supplement or term sheet.

Exercise of Common Warrants

        Each offered common warrant will entitle the holder thereof to purchase the number of shares of Holdings' common stock at the exercise price set forth in, or calculable from, the prospectus supplement or term sheet relating to the common warrants. After the close of business on the applicable expiration date, unexercised common warrants will be void.

39


Table of Contents

        Common warrants may be exercised by payment to the common warrant agent of the exercise price and by delivery to the common warrant agent of the related common warrant certificate, with the reverse side thereof properly completed. Common warrants will be deemed to have been exercised upon receipt of the exercise price and the common warrant certificate or certificates. Upon receipt of the payment and the properly completed common warrant certificates, we will, as soon as practicable, deliver the shares of common stock purchased upon the exercise.

        If fewer than all of the common warrants represented by any common warrant certificate are exercised, a new common warrant certificate will be issued for the unexercised offered common warrants. The holder of an offered common warrant will be required to pay any tax or other governmental charge that may be imposed in connection with any transfer involved in the issuance of common stock purchased upon exercise.

Modifications

        There are three types of changes Holdings can make to a common warrant agreement and the common warrants issued thereunder.

        Changes Requiring Your Approval.    First, there are changes that cannot be made to your common warrants without your specific approval. Those types of changes include modifications and amendments that:

        Changes Not Requiring Approval.    The second type of change does not require any vote by holders of the common warrants. This type of change is limited to clarifications and other changes that would not materially adversely affect the interests of the holders of the common warrants.

        Changes Requiring a Majority Vote.    Any other change to the common warrant agreement requires a vote in favor by holders of not fewer than a majority in number of the then outstanding unexercised common warrants affected thereby. Most changes fall into this category.

Common Warrant Adjustments

        The terms and conditions on which the exercise price of and/or the number of shares of common stock covered by a common warrant are subject to adjustment will be set forth in the common warrant agreement and the prospectus supplement or term sheet. The terms will include provisions for adjusting the exercise price and/or the number of shares of common stock covered by the common warrant; the events requiring the adjustment; the events upon which we may, in lieu of making the adjustment, make proper provisions so that the holder of a common warrant, upon exercise thereof, would be treated as if the holder had exercised the common warrant prior to the occurrence of the events; and provisions affecting exercise in the event of certain events affecting the common stock.

No Rights as Stockholders

        Holders of common warrants are not entitled, by virtue of being holders, to receive dividends or to vote, consent or receive notice as our stockholders in respect of any meeting of stockholders for the election of our directors or for any other matter, or exercise any other rights whatsoever as our stockholders.

Table of Contents


DESCRIPTION OF COMMON STOCK

        The following summary describes elements of Holdings' Certificate of Incorporation and Bylaws.

        Holdings' authorized capital stock consists of (i) 150,000,000 shares of common stock, par value $.01 per share, of which 112,544,942 shares were issued and outstanding as of February 11, 2020, (ii) 10,000,000 shares of preferred stock, par value $.01 per share of which no shares are issued and outstanding and (iii) 40,000,000 shares of series common stock, par value $.01 per share, of which no shares are issued and outstanding. The following description of Holdings' capital stock and related matters is qualified in its entirety by reference to the Certificate of Incorporation and the Bylaws, copies of which are on file with the SEC.

Common Stock

        Holders of common stock are entitled to one vote per share on all matters to be voted upon by the stockholders. The holders of common stock do not have cumulative voting rights in the election of directors. Holders of common stock are entitled to receive dividends if, as and when dividends are declared from time to time by Holdings' Board of Directors out of funds legally available therefor, after payment of dividends required to be paid on outstanding preferred stock or series common stock (as described below), if any. In the event of liquidation, dissolution or winding up of Holdings, the holders of common stock are entitled to share ratably in all assets remaining after payment of liabilities and accrued but unpaid dividends and liquidation preferences on any outstanding preferred stock or series common stock of Holdings. The common stock has no preemptive or conversion rights and is not subject to further calls or assessment by Holdings. There are no redemption or sinking fund provisions applicable to the common stock. The common stock sold by Holdings in an offering pursuant to this prospectus, when sold to the underwriters of such offering in the manner described in this prospectus and the prospectus supplement or term sheet relating to such offering will be, and all currently outstanding common stock of Holdings is, duly authorized, validly issued, fully paid and non-assessable.

Preferred Stock and Series Common Stock

        The Certificate of Incorporation authorizes the Board of Directors to establish one or more series of preferred stock and series common stock and to determine, with respect to any series of preferred stock or series common stock, the terms and rights of such series, including (i) the designation of the series, (ii) the number of shares of the series, which number the Board may thereafter (except where otherwise provided in the preferred stock or series common stock designation) increase or decrease (but not below the number of shares thereof then outstanding), (iii) whether dividends, if any, will be cumulative or non-cumulative and the dividend rate of the series, (iv) the dates at which dividends, if any, will be payable, (v) the redemption rights and price or prices, if any, for shares of the series, (vi) the terms and amounts of any sinking fund provided for the purchase or redemption of shares of the series, (vii) the amounts payable on shares of the series in the event of any voluntary or involuntary liquidation, dissolution or winding-up of the affairs of Holdings, (viii) whether the shares of the series will be convertible into shares of any other class or series, or any other security, of Holdings or any other corporation, and, if so, the specification of such other class or series or such other security, the conversion price or prices or rate or rates, any adjustments thereof, the date or dates as of which such shares shall be convertible and all other terms and conditions upon which such conversion may be made, (ix) restrictions on the issuance of shares of the same series or of any other class or series, and (x) the voting rights, if any, of the holders of such series. The authorized shares of preferred stock and series common stock, as well as shares of common stock, will be available for issuance without further action by Holdings' stockholders, unless such action is required by applicable law or the rules of any stock exchange or automated quotation system on which Holdings' securities may be listed or traded.

41


Table of Contents

        Although the Board has no intention at the present time of doing so, it could issue a series of preferred stock or series common stock that could, depending on the terms of such series, impede the completion of a merger, tender offer or other takeover attempt. The Board will make any determination to issue such shares based on its judgment as to the best interests of Holdings and its stockholders. The Board, in so acting, could issue preferred stock or series common stock having terms that could discourage an acquisition attempt or other transaction that some, or a majority, of Holdings' stockholders might believe to be in their best interests or in which stockholders might receive a premium for their stock over the then-current market price of such stock.

Authorized but Unissued Capital Stock

        Delaware law does not require stockholder approval for any issuance of authorized shares. However, the listing requirements of the New York Stock Exchange, which would apply so long as the common stock remains listed on the New York Stock Exchange, require stockholder approval of certain issuances equal to or exceeding 20% of the then outstanding voting power or then outstanding number of shares of common stock. These additional shares may be used for a variety of corporate purposes, including future public offerings to raise additional capital or to facilitate acquisitions.

        One of the effects of the existence of unissued and unreserved common stock, preferred stock and series common stock may be to enable Holdings' Board of Directors to issue shares to persons friendly to current management, which issuance could render more difficult or discourage an attempt to obtain control of Holdings by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of Holdings' management and possibly deprive the stockholders of opportunities to sell their shares of common stock at prices higher than prevailing market prices.

The Delaware General Corporation Law

        Holdings is a Delaware corporation subject to Section 203 of the Delaware General Corporation Law (the "DGCL"). Section 203 provides that, subject to certain exceptions specified therein, a Delaware corporation shall not engage in certain "business combinations" with any "interested stockholder" for a three-year period following the time that such stockholder became an interested stockholder unless (i) the corporation has elected in its certificate of incorporation not to be governed by Section 203 (Holdings has not made such an election), (ii) prior to such time, the board of directors of the corporation approved either the business combination or the transaction which resulted in the stockholder becoming an interested stockholder, (iii) upon consummation of the transaction which resulted in the stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction commenced (excluding certain shares), or (iv) at or subsequent to such time, the business combination is approved by the board of directors of the corporation and by the affirmative vote of at least 662/3% of the outstanding voting stock which is not owned by the interested stockholder. The three-year prohibition also does not apply to certain business combinations proposed by an interested stockholder following the announcement or notification of certain extraordinary transactions involving the corporation and a person who had not been an interested stockholder during the previous three years or who became an interested stockholder with the approval of a majority of the corporation's directors. The term "business combination" is defined generally to include mergers or consolidations between a Delaware corporation and an "interested stockholder," transactions with an "interested stockholder" involving the assets or stock of the corporation or its majority-owned subsidiaries and transactions which increase an interested stockholder's percentage ownership of stock. Except as specified in Section 203 of the DGCL, an "interested stockholder" is defined to include any person, other than the corporation and any direct or indirect majority-owned subsidiary, that is (x) the owner of 15% or more of the outstanding voting stock of the corporation, or is an affiliate or associate of the corporation and was

42


Table of Contents

the owner of 15% or more of the outstanding voting stock of the corporation, at any time within three years immediately prior to the relevant date or (y) the affiliates and associates of any such person.

        Under certain circumstances, Section 203 makes it more difficult for a person who would be an "interested stockholder" to effect various business combinations with a corporation for a three-year period. The provisions of Section 203 may encourage companies interested in acquiring Holdings to negotiate in advance with Holdings' Board of Directors, because the stockholder approval requirement would be avoided if the Board of Directors approves either the business combination or the transaction which results in the stockholder becoming an interested stockholder. Such provisions also may have the effect of preventing changes in Holdings' Board of Directors and may make it more difficult to accomplish transactions which stockholders may otherwise deem to be in their best interests.

Certificate of Incorporation; Bylaws

        The Certificate of Incorporation and the Bylaws contain certain provisions that could make more difficult the acquisition of Holdings by means of a tender offer, a proxy contest or otherwise.

        Classified Board.    The Certificate of Incorporation provides that Holdings' Board of Directors will be divided into three classes of directors, with the classes to be as nearly equal in number as possible. As a result, approximately one-third of the Board of Directors will be elected each year. The classification of directors will have the effect of making it more difficult for stockholders to change the composition of Holdings' Board. The Certificate of Incorporation provides that, subject to any rights of holders of Preferred Stock or Series Common Stock to elect additional directors under specified circumstances, the number of directors will be fixed in the manner provided in the Bylaws. The Certificate of Incorporation and the Bylaws provide that the number of directors will be fixed from time to time exclusively pursuant to a resolution adopted by the Board, but must consist of not less than three directors. In addition, the Certificate of Incorporation provides that, subject to any rights of holders of Preferred Stock, and unless the Board otherwise determines, any vacancies will be filled only by the affirmative vote of a majority of the remaining directors, though less than a quorum. The Holdings' Board of Directors currently consists of eight directors, but will be increased to 11 members as a condition to, and effective upon, the completion of the merger with MPG.

        Removal of Directors.    Under the DGCL, unless otherwise provided in the Certificate of Incorporation, directors serving on a classified board may be removed by the stockholders only for cause. In addition, the Certificate of Incorporation and the Bylaws provide that directors may be removed only for cause and only upon the affirmative vote of holders of at least 75% of the voting power of all the then outstanding shares of stock entitled to vote generally in the election of directors ("Voting Stock"), voting together as a single class.

        Stockholder Action.    The Certificate of Incorporation and the Bylaws provide that stockholder action can be taken only at an annual or special meeting of stockholders and may not be taken by written consent in lieu of a meeting. The Certificate of Incorporation and the Bylaws provide that special meetings of stockholders can be called only by Holdings' Chief Executive Officer or pursuant to a resolution adopted by the Board. Stockholders are not permitted to call a special meeting or to require that the Board call a special meeting of stockholders. Moreover, the business permitted to be conducted at any special meeting of stockholders is limited to the business brought before the meeting pursuant to the notice of meeting given by Holdings.

        Advance Notice Procedures.    The Bylaws establish an advance notice procedure for stockholders to make nominations of candidates for election as directors, or bring other business before an annual or special meeting of stockholders of Holdings (the "Stockholders Notice Procedure"). The Stockholders Notice Procedure provides that only persons who are nominated by, or at the direction of the Board of Directors, the Chairman of the Board, or by a stockholder who has given timely written notice to the

43


Table of Contents

Secretary of Holdings prior to the meeting at which directors are to be elected, will be eligible for election as directors of Holdings. The Stockholders Notice Procedure also provides that at an annual meeting only such business may be conducted as has been brought before the meeting pursuant to the notice of meeting delivered by Holdings or by, or at the direction of, the Chairman of the Board or by a stockholder who is entitled to vote at the meeting and who has given timely written notice to the Secretary of Holdings of such stockholder's intention to bring such business before such meeting. Under the Stockholders Notice Procedure, for notice of stockholder nominations to be made at an annual meeting to be timely, such notice must be received by Holdings not less than 70 days nor more than 90 days prior to the first anniversary of the previous year's annual meeting (or, if the date of the annual meeting is advanced by more than 20 days or delayed by more than 70 days from such anniversary date, not earlier than the 90th day prior to such meeting and not later than the later of (x) the 70th day prior to such meeting and (y) the 10th day after public announcement of the date of such meeting is first made). Notwithstanding the foregoing, in the event that the number of directors to be elected is increased and there is no public announcement naming all of the nominees for director or specifying the size of the increased Board of Directors made by Holdings at least 80 days prior to the first anniversary of the preceding year's annual meeting, a stockholder's notice will be timely, but only with respect to nominees for any new positions created by such increase, if it is received by Holdings not later than the 10th day after such public announcement is first made by Holdings. Under the Stockholders Notice Procedure, for notice of a stockholder nomination to be made at a special meeting at which directors are to be elected to be timely, such notice must be received by Holdings not earlier than the 90th day before such meeting and not later than the later of (x) the 70th day prior to such meeting and (y) the 10th day after the public announcement of the date of such meeting is first made. In addition, under the Stockholders Notice Procedure, a stockholder's notice to Holdings proposing to nominate a person for election as a director or relating to the conduct of business other than the nomination of directors must contain certain specified information. If the Chairman of the Board or other officer presiding at a meeting determines that a person was not nominated, or other business was not brought before the meeting, in accordance with the Stockholders Notice Procedure, such person will not be eligible for election as a director, or such business will not be conducted at such meeting, as the case may be.

        Proxy Access.    The Bylaws contain a proxy access provision which allows eligible stockholders who comply with the requirements set forth in the ByLaws to include their own director nominees in Holdings' proxy statement along with the candidates nominated by the Board. Pursuant to the proxy access provision, a stockholder, or group of up to 20 stockholders, owning an aggregate of 3% or more of Holdings' outstanding capital stock continuously for at least three years, may nominate a candidate for election to the Board and such candidate will be included in Holdings' proxy statement for the applicable annual meeting of Holdings' stockholders. Holdings will not be required, however, to include in its proxy statement more stockholder nominees than that number constituting the greater of (i) two and (ii) 20% of the total number of directors of Holdings then serving on the Board.

        Liability of Directors; Indemnification.    The Certificate of Incorporation provides that a director will not be personally liable for monetary damages to Holdings or its stockholders for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the DGCL. The Certificate of Incorporation also provides that each current or former director, officer, employee or agent of Holdings, or each such person who is or was serving or who had agreed to serve at the request of Holdings as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise (including the heirs, executors, administrators or estate of such person), will be indemnified by Holdings to the full extent permitted by the DGCL, as the same exists or may in the future be amended (but, in the case of any such amendment, only to the extent that such amendment permits Holdings to provide broader indemnification rights than said law permitted Holdings to provide prior to such amendment). The Certificate of Incorporation also specifically authorizes Holdings to enter into agreements with any

44

person providing for indemnification greater or different than that provided by the Certificate of Incorporation.

        Amendment.    The Certificate of Incorporation provides that the affirmative vote of the holders of at least 75% of the voting power of the outstanding shares of Voting Stock, voting together as a single class, is required to amend provisions of the Certificate of Incorporation relating to the prohibition of stockholder action without a meeting; the number, election and term of Holdings' directors; and the removal of directors. The Certificate of Incorporation further provides that the Bylaws may be amended by the Board or by the affirmative vote of the holders of at least 75% of the outstanding shares of Voting Stock, voting together as a single class.

        The description set forth above is intended as a summary only and is qualified in its entirety by reference to the Certificate of Incorporation and the Bylaws, copies of which are exhibits to the Registration Statement of which this prospectus is a part.

        The registrar and transfer agent for the common stock is Computershare Trust Co. of New York.

Listing

        Holdings' common stock is listed on the New York Stock Exchange under the symbol "AXL."


DESCRIPTION OF PREFERRED STOCK

        Under Holdings' Certificate of Incorporation, it is authorized to adopt resolutions providing for the issuance, in one or more series, of up to 10,000,000 shares of preferred stock, $.01 par value, with the powers, preferences and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof adopted by the Board of Directors or a duly authorized committee thereof.

        Because this section is a summary, it does not describe every aspect of Holdings' preferred stock. We urge you to read Holdings' Certificate of Incorporation and the certificate of designations creating your preferred stock because they, and not this description, define your rights as a holder of preferred stock. Holdings has filed the Certificate of Incorporation and will file the certificate of designations with the SEC. See "Where You Can Find More Information" for information on how to obtain copies of these documents.

        The specific material terms of any preferred stock proposed to be sold under this prospectus and an attached prospectus supplement or term sheet will be described in the prospectus supplement or term sheet. If so indicated in the prospectus supplement or term sheet, the terms of the offered preferred stock may differ from the terms set forth below.

General

        Unless otherwise specified in the prospectus supplement or term sheet relating to the offered preferred stock, each series of preferred stock will rank on a parity as to dividends and distribution of assets upon liquidation and in all other respects with all other series of preferred stock. The preferred stock will, when issued, be fully paid and nonassessable and holders thereof will have no preemptive rights.

        You should read the prospectus supplement or term sheet for the material terms of the preferred stock offered thereby, including the following:

45


Table of Contents

        Subject to Holdings' Certificate of Incorporation and to any limitations contained in its outstanding preferred stock, Holdings may issue additional series of preferred stock, at any time or from time to time, with the powers, preferences and relative, participating, optional or other special rights and qualifications, limitations or restrictions thereof, as the Board of Directors or any duly authorized committee thereof may determine, all without further action of its stockholders, including holders of its then outstanding preferred stock.

        If applicable, the prospectus supplement or term sheet will also contain a discussion of the material United States federal income tax considerations relevant to the offering.

Dividends

        Holders of preferred stock will be entitled to receive cash dividends, when, as and if declared by the Board of Directors, out of Holdings' assets legally available for payment, at the rate and on the dates set forth in the prospectus supplement or term sheet. Each dividend will be payable to holders of record as they appear on Holdings' stock books on the record date fixed by the Board of Directors. Dividends, if cumulative, will be cumulative from and after the date set forth in the applicable prospectus supplement or term sheet.

        Holdings may not:

if there are arrearages in dividends or failure in the payment of the sinking fund or redemption obligations on any of Holdings' preferred stock and, in the case of the first bullet point above, if

46


Table of Contents

dividends in full for the current quarterly dividend period have not been paid or declared on any of Holdings' preferred stock.

        Dividends in full may not be declared or paid or set apart for payment on any series of preferred stock unless:

        Any dividends declared or paid when dividends are not so declared, paid or set apart in full will be shared ratably by the holders of all series of preferred stock in proportion to the respective arrearages and undeclared and unpaid current cumulative dividends. No interest, or sum of money in lieu of interest, will be payable in respect of any dividend payment or payments that may be in arrears.

Conversion and Exchange

        If the preferred stock will be convertible into or exchangeable for common stock or other securities, the prospectus supplement or term sheet will set forth the terms and conditions of that conversion or exchange, including the conversion price or exchange ratio (or the method of calculating the same), the conversion or exchange period (or the method of determining the same), whether conversion or exchange will be mandatory or at the option of the holder or us, the events requiring an adjustment of the conversion price or the exchange ratio and provisions affecting conversion or exchange in the event of the redemption of that preferred stock. These terms may also include provisions under which the number of shares of common stock or the number or amount of other securities to be received by the holders of that preferred stock upon conversion or exchange would be calculated according to the market price of the common stock or those other securities as of a time stated in the prospectus supplement or term sheet.

Liquidation Rights

        In the event of Holdings' voluntary or involuntary liquidation, dissolution or winding up, the holders of each series of the preferred stock will be entitled to receive out of the assets that are available for distribution to stockholders, before any distribution of assets is made to holders of any junior stock, liquidating distributions in the amount set forth in the applicable prospectus supplement or term sheet plus all accrued and unpaid dividends. If, upon Holdings' voluntary or involuntary liquidation, dissolution or winding up, the amounts payable with respect to the preferred stock are not paid in full, the holders of preferred stock of each series will share ratably in the distribution of assets in proportion to the full respective preferential amounts to which they are entitled. After payment of the full amount of the liquidating distribution to which they are entitled, the holders of the preferred stock will not be entitled to any further participation in any distribution of assets. Holdings' consolidation or merger with or into any other corporation or corporations or a sale of all or substantially all of its assets will not be deemed to be a liquidation, dissolution or winding up for purposes of these provisions.

Redemption

        If so provided in the prospectus supplement or term sheet, the offered preferred stock may be redeemable in whole or in part at Holdings' option at the times and at the redemption prices set forth therein.

        If dividends on any series of preferred stock are in arrears or Holdings has failed to fulfill its sinking fund or redemption obligations with respect to any series of preferred stock, Holdings may not

47


Table of Contents

purchase or redeem shares of preferred stock or any other capital stock ranking on a parity with or junior to the preferred stock as to dividends or upon liquidation, nor permit any subsidiary to do so, without in either case the consent of the holders of at least two-thirds of each series of preferred stock then outstanding; provided, however, that:

Voting Rights

        Except as indicated below or in the prospectus supplement or term sheet, or except as expressly required by applicable law, the holders of the preferred stock will not be entitled to vote. As used herein, the term "applicable preferred stock" means those series of preferred stock to which the provisions described herein are expressly made applicable by resolutions of the Board of Directors.

        If the equivalent of six quarterly dividends payable on any shares of any series of applicable preferred stock are in default (whether or not the dividends have been declared or the defaulted dividends are consecutive), the number of directors will be increased by two and the holders of all outstanding series of applicable preferred stock, voting as a single class without regard to series, will be entitled to elect the two additional directors until four consecutive quarterly dividends are paid or declared and set apart for payment, if the shares are cumulative, or until all arrearages in dividends and dividends in full for the current quarterly period are paid or declared and set apart for payment, if the shares are non-cumulative, whereupon all voting rights described herein will be divested from the applicable preferred stock. The holders of applicable preferred stock may exercise their special class voting rights at meetings of the stockholders for the election of directors or at special meetings for the purpose of electing directors, in either case at which the holders of not less than one-third of the aggregate number of shares of applicable preferred stock are present in person or by proxy.

        The affirmative vote of the holders of at least two-thirds of the outstanding shares of any series of preferred stock will be required:

        In addition, the affirmative vote of the holders of a majority of all the shares of Holdings' preferred stock then outstanding will be required to increase the authorized amount of preferred stock.


SPECIAL PROVISIONS RELATING TO FOREIGN CURRENCY DEBT SECURITIES

General

        Unless otherwise indicated in the applicable prospectus supplement or term sheet, the debt securities will be denominated in U.S. dollars, payments of principal of, premium, if any, and interest on the debt securities will be made in U.S. dollars and payment of the purchase price of the debt securities must be made in immediately available funds. If any of the debt securities ("Foreign

48


Table of Contents

Currency Debt Securities") are to be denominated or payable in a currency (a "specified currency") other than U.S. dollars, the following provisions will apply in addition to, and to the extent inconsistent therewith will replace, the description of general terms and provisions of debt securities set forth in the accompanying prospectus and elsewhere in this prospectus.

        A prospectus supplement or term sheet with respect to any Foreign Currency Debt Security (which may include information with respect to applicable current foreign exchange controls) is a part of this prospectus and prospectus supplement or term sheet. Any information concerning exchange rates is furnished as a matter of information only and should not be regarded as indicative of the range of or trends in fluctuations in currency exchange rates that may occur in the future.

Currencies

        We may offer Foreign Currency Debt Securities denominated and/or payable in a specified currency or specified currencies. Unless otherwise indicated in the applicable prospectus supplement or term sheet, purchasers are required to pay for Foreign Currency Debt Securities in the specified currency. At the present time, there are limited facilities in the United States for conversion of U.S. dollars into specified currencies and vice versa, and banks may elect not to offer non-U.S. dollar checking or savings account facilities in the United States. However, if requested on or prior to the fifth Business Day preceding the date of delivery of the Foreign Currency Debt Securities, or by such other day as determined by the agent who presents such offer to purchase Foreign Currency Debt Securities to us, such agent may be prepared to arrange for the conversion of U.S. dollars into the specified currency set forth in the applicable prospectus supplement or term sheet to enable the purchasers to pay for the Foreign Currency Debt Securities. Each such conversion will be made by the agents on such terms and subject to such conditions, limitations and charges as the agents may from time to time establish in accordance with their regular foreign exchange practices. All costs of exchange will be borne by the purchasers of the Foreign Currency Debt Securities.

        Information about the specified currency in which a particular Foreign Currency Debt Security is denominated and/or payable, including historical exchange rates and a description of the currency and any exchange controls, will be set forth in the applicable prospectus supplement or term sheet.

Payment of Principal and Interest

        The principal of, premium, if any, and interest on Foreign Currency Debt Securities are payable by us in the specified currency. Currently, banks do not generally offer non-U.S. dollar-denominated account facilities in their offices in the United States, although they are permitted to do so. Accordingly, a holder of Foreign Currency Debt Securities will be paid in U.S. dollars converted from the specified currency unless the holder is entitled to elect, and does elect, to be paid in the specified currency, or as otherwise specified in the applicable prospectus supplement or term sheet.

        Any U.S. dollar amount to be received by a holder of a Foreign Currency Debt Security will be based on the highest bid quotation in The City of New York received by an agent for us specified in the applicable prospectus supplement or term sheet (the "Exchange Rate Agent") at approximately 11:00 A.M., New York City time, on the second Business Day preceding the applicable payment date from three recognized foreign exchange dealers (one of whom may be the Exchange Rate Agent) selected by the Exchange Rate Agent and approved by us for the purchase by the quoting dealer of the specified currency for U.S. dollars for settlement on the payment date in the aggregate amount of the specified currency payable to all holders of Foreign Currency Debt Securities scheduled to receive U.S. dollar payments and at which the applicable dealer commits to execute a contract. If three bid quotations are not available, payments will be made in the specified currency. All currency exchange costs will be borne by the holder of the Foreign Currency Debt Security by deductions from such payments.

Table of Contents

        Unless otherwise indicated in the applicable prospectus supplement or term sheet, a holder of Foreign Currency Debt Securities may elect to receive payment of the principal of, and premium, if any, and interest on the Foreign Currency Debt Securities in the specified currency by transmitting a written request for such payment to the corporate trust office of the trustee in The City of New York on or prior to the regular record date or at least fifteen calendar days prior to Maturity Date, as the case may be. This request may be in writing (mailed or hand delivered) or sent by cable, telex or other form of facsimile transmission. A holder of a Foreign Currency Debt Security may elect to receive payment in the specified currency for all principal, premium, if any, and interest payments and need not file a separate election for each payment. This election will remain in effect until revoked by written notice to the trustee, but written notice of any revocation must be received by the trustee on or prior to the regular record date or at least fifteen calendar days prior to the Maturity Date, as the case may be. Holders of Foreign Currency Debt Securities whose debt securities are to be held in the name of a broker or nominee should contact their brokers or nominees to determine whether and how an election to receive payments in the specified currency may be made.

        Unless otherwise specified in the applicable prospectus supplement or term sheet, if the specified currency is other than U.S. dollars, a beneficial owner of the related global security who elects to receive payments of principal, premium, if any, and/or interest, if any, in the specified currency must notify its participant through which it owns its beneficial interest on or prior to the applicable record date or at least fifteen calendar days prior to the Maturity Date, as the case may be, of such beneficial owner's election. The participant must notify the depositary of such election on or prior to the third Business Day after such record date or at least 12 calendar days prior to the Maturity Date, as the case may be, and the depositary will notify the trustee of such election on or prior to the fifth Business Day after such record date or at least ten calendar days prior to the Maturity Date, as the case may be. If complete instructions are received by the participant from the beneficial owner and forwarded by the participant to the depositary, and by the depositary to the trustee, on or prior to such dates, then the beneficial owner will receive payments in the specified currency. See "Description of Debt Securities—Global Securities" in the accompanying prospectus.

        Principal and interest on Foreign Currency Debt Securities paid in U.S. dollars will be paid in the manner specified in the accompanying prospectus supplement or term sheet and this prospectus with respect to debt securities denominated in U.S. dollars. Interest on Foreign Currency Debt Securities paid in the specified currency will be paid by check mailed on an Interest Payment Date other than a Maturity Date to the persons entitled thereto to the addresses of such holders as they appear in the security register or, at our option, by wire transfer to a bank account maintained by the holder in the country of the specified currency. The principal of, premium, if any, and interest on Foreign Currency Debt Securities, together with interest accrued and unpaid thereon, due on the Maturity Date will be paid, in the specified currency in immediately available funds upon surrender of such debt securities at the corporate trust office of the trustee in The City of New York, or, at our option, by wire transfer to such bank account of immediately available funds to an account with a bank designated at least 15 calendar days prior to the Maturity Date by the applicable registered holder, provided the particular bank has appropriate facilities to make these payments and the particular Foreign Currency Debt Security is presented and surrendered at the office or agency maintained by us for this purpose in the Borough of Manhattan, The City of New York, in time for the trustee to make these payments in accordance with its normal procedures.

Payment Currency

        If a specified currency is not available for the payment of principal, premium or interest with respect to a Foreign Currency Debt Security due to the imposition of exchange controls or other circumstances beyond our control, we will be entitled to satisfy our obligations to holders of Foreign Currency Debt Securities by making such payment in U.S. dollars on the basis of the noon buying rate

50


Table of Contents

in The City of New York for cable transfers of the specified currency as certified for customs purposes (or, if not so certified, as otherwise determined) by the Federal Reserve Bank of New York (the "Market Exchange Rate") as computed by the Exchange Rate Agent on the second Business Day prior to such payment or, if not then available, on the basis of the most recently available Market Exchange Rate or as otherwise indicated in an applicable prospectus supplement or term sheet. Any payment made under these circumstances in U.S. dollars where the required payment is in a specified currency will not constitute a default under the Indenture with respect to the Debt Securities.

        All determinations referred to above made by the Exchange Rate Agent will be at its sole discretion and will, in the absence of manifest error, be conclusive for all purposes and binding on the holders of the Foreign Currency Debt Securities.

        AS INDICATED ABOVE, AN INVESTMENT IN FOREIGN CURRENCY DEBT SECURITIES OR CURRENCY INDEXED DEBT SECURITIES INVOLVES SUBSTANTIAL RISKS, AND THE EXTENT AND NATURE OF SUCH RISKS CHANGE CONTINUOUSLY. AS WITH ANY INVESTMENT IN A SECURITY, PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR OWN FINANCIAL AND LEGAL ADVISORS AS TO THE RISKS ENTAILED IN AN INVESTMENT IN FOREIGN CURRENCY DEBT SECURITIES OR CURRENCY INDEXED DEBT SECURITIES. SUCH DEBT SECURITIES ARE NOT AN APPROPRIATE INVESTMENT FOR PROSPECTIVE PURCHASERS WHO ARE UNSOPHISTICATED WITH RESPECT TO FOREIGN CURRENCY MATTERS.


PLAN OF DISTRIBUTION

        We may sell the offered securities:

        Any underwriters or agents will be identified and their discounts, commissions and other items constituting underwriters' compensation and any securities exchanges on which the securities are listed will be described in the applicable prospectus supplement or term sheet.

        We (directly or through agents) may sell, and the underwriters may resell, the offered securities in one or more transactions, including negotiated transactions, at a fixed public offering price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices.

        In order to facilitate the offering of the debt securities, the underwriters or agents may engage in transactions that stabilize, maintain or otherwise affect the price of the debt securities and our common stock. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the underwriters or agents of a greater number of debt securities than they are required to purchase in the offering. "Covered" short sales are sales made in an amount not greater than the underwriters' or agents' option to purchase additional debt securities from us in the offering. The underwriters or agents may close out any covered short position by either exercising the option to purchase additional debt securities or purchasing debt securities in the open market. In determining the source of debt securities to close out the covered short position, the underwriters or agents will consider, among other things, the price of debt securities available for purchase in the open market as compared to the price at which they may purchase debt securities through the option. "Naked" short sales are sales in excess of the option. The underwriters or agents must close out any naked short position by purchasing debt securities in open market. A naked short position is more likely to be created if the underwriters or agents are concerned that there

51


Table of Contents

may be a downward pressure on the price of the debt securities in the open market after pricing that could adversely affect investors who purchase in the offering. Stabilizing transactions consist of certain bids for or purchases of the debt securities made by the underwriters or agents in the open market prior to the completion of the offering. Any of these activities may stabilize or maintain the market price of the debt securities above independent market levels. The underwriters or agents are not required to engage in these activities, and may end any of these activities at any time.

        In connection with the sale of offered securities, the underwriters or agents may receive compensation from us or from purchasers of the offered securities for whom they may act as agents. The underwriters may sell offered securities to or through dealers, who may also receive compensation from purchasers of the offered securities for whom they may act as agents. Compensation may be in the form of discounts, concessions or commissions. Underwriters, dealers and agents that participate in the distribution of the offered securities may be underwriters as defined in the Securities Act of 1933 (the "Act"), and any discounts or commissions received by them from us and any profit on the resale of the offered securities by them may be treated as underwriting discounts and commissions under the Act.

        We will indemnify the underwriters and agents against certain civil liabilities, including liabilities under the Act, or contribute to payments they may be required to make in respect of such liabilities.

        Underwriters, dealers and agents may engage in transactions with, or perform services for, us or our affiliates in the ordinary course of their businesses.

        If so indicated in the prospectus supplement or term sheet relating to a particular series or issue of offered securities, we will authorize underwriters, dealers or agents to solicit offers by certain institutions to purchase the offered securities from us under delayed delivery contracts providing for payment and delivery at a future date. These contracts will be subject only to those conditions set forth in the prospectus supplement or term sheet, and the prospectus supplement or term sheet will set forth the commission payable for solicitation of these contracts.


LEGAL MATTERS

        The validity of the Holdings and AAM Inc. securities will be passed upon for us by Shearman & Sterling LLP, 599 Lexington Avenue, New York, New York 10022. David E. Barnes, who is General Counsel of Holdings and AAM Inc., will give us an opinion about the validity of the guarantees by the Subsidiary Guarantors. Mr. Barnes owns Holdings common stock.


EXPERTS

        The consolidated financial statements, and the related financial statement schedule, incorporated in this prospectus by reference from Holdings' Annual Report on Form 10-K, and the effectiveness of Holdings' internal control over financial reporting have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report, which is incorporated herein by reference. Such consolidated financial statements and financial statement schedule have been so incorporated in reliance upon the report of such firm given upon their authority as experts in accounting and auditing.
