Non-GAAP and non-IFRS financial measures

In addition to results reported in accordance with GAAP and IFRS as issued by the IASB in this offering memorandum, we have provided certain non-GAAP and non-IFRS financial measures such as EBITDA, Adjusted EBITDA, Segment Adjusted EBITDA, Adjusted Revenue, Free Cash Flow, Adjusted Free Cash Flow and Adjusted Operating Profit. Such information is reconciled to its closest GAAP or IFRS measure, as applicable, in accordance with SEC rules under "Summary-AAM Holdings Summary Consolidated Financial Data" and "Summary-Dowlais Summary Consolidated Financial Data."

AAM Holdings defines EBITDA to be earnings before interest expense, income taxes, depreciation and amortization. AAM Holdings defines Adjusted EBITDA as EBITDA excluding the impact of restructuring and acquisition-related costs, debt refinancing and redemption costs, gains or losses on the derivative associated with the Combination, gains or losses on equity securities, pension curtailment and settlement charges, impairment charges and non-recurring items. AAM Holdings defines Segment Adjusted EBITDA as EBITDA for its reportable segments excluding the impact of restructuring and acquisition-related costs, debt refinancing and redemption costs, gains or losses on the derivative associated with the Combination, gains or losses on equity securities, pension curtailment and settlement charges, impairment charges and non-recurring items. AAM Holdings defines Free Cash Flow to be net cash provided by operating activities less capital expenditures net of proceeds from the sale of property, plant and equipment and from government grants. AAM Holdings defines Adjusted Free Cash Flow as Free Cash Flow excluding the impact of cash payments for restructuring and acquisition-related costs and cash payments related to the Malvern fire, including payments for capital expenditures, net of recoveries.

Dowlais defines Adjusted Revenue as external revenue including Dowlais' share of revenue of equity accounted investments. Dowlais defines Adjusted Operating Profit as operating profit excluding items which are significant in size or volatility or by nature are non-trading or non-recurring and including the adjusted operating profit of equity accounted investments. Dowlais defines Adjusted EBITDA as Adjusted Operating Profit after adding back depreciation and impairment of property, plant and equipment and amortization of computer software and development costs, including that of equity accounted investments. Dowlais defines Free Cash Flow as cash generated after accounting for all trading costs, restructuring, pension contributions, and tax payments, but before any cash flows associated with financing activities (i.e. net cash from operating and investing activities). Dowlais defines Adjusted Free Cash Flow as Free Cash Flow adjusted for cash flows related to its demerger from Melrose Industries PLC, cash spend on AAM combination and net cash on business disposals.

We believe that EBITDA, Adjusted EBITDA, Segment Adjusted EBITDA, Adjusted Revenue, Free Cash Flow, Adjusted Free Cash Flow and Adjusted Operating Profit 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. We also use Segment Adjusted EBITDA as the measure of earnings to assess the performance of each segment and determine the resources to be allocated to the segments. We also believe Free Cash Flow and Adjusted Free Cash Flow are meaningful measures as they are commonly utilized by management and investors to assess our ability to generate cash flow from business operations to repay debt and return capital to our stockholders. EBITDA, Adjusted EBITDA, Free Cash Flow and Adjusted Free Cash Flow are also key metrics used in our calculation of incentive compensation. These non- GAAP and non-IFRS financial measures are not and should not be considered a substitute for any GAAP or IFRS measure. Additionally, non-GAAP and non-IFRS financial measures as presented may not be comparable to similarly titled measures reported by other companies.

GKN Powder Metallurgy serves both the automotive and industrial end markets.

Transaction overview

On January 29, 2025, we announced the terms of an offer (the "Offer") by AAM Holdings to acquire the entire issued and to be issued share capital of Dowlais. Under the terms of the Offer, shareholders of Dowlais will be entitled to receive, for each ordinary share of Dowlais (each, a "Dowlais Share" and, collectively, the "Dowlais Shares"), 43 pence per share in cash and 0.0881 new shares of common stock of AAM Holdings, par value $0.01 per share (each share, an "AAM Share" and, collectively, the "AAM Shares"). In addition to the consideration payable in connection with the Combination, shareholders of Dowlais also received the payment of a final cash dividend by Dowlais of 2.8 pence for each Dowlais Share paid on May 29, 2025 (the "FY24 Final Dividend").

The Combination has been unanimously approved by the Boards of Directors of AAM Holdings and Dowlais and by both companies' shareholders. Following the close of the transaction, the combined company will be headquartered in Detroit, Michigan and will be led by AAM's Chairman and CEO. The transaction is expected to close by the end of 2025, subject to the receipt of regulatory approvals and satisfaction of customary closing conditions.

We intend to use the net proceeds from this offering, together with borrowings under the Credit Agreement and cash on hand, (i) to pay the cash consideration payable in connection with the Combination and related fees and expenses, (ii) to repay in full all outstanding borrowings under the Dowlais Credit Facilities and to pay related fees, expenses and premiums, after which Dowlais Credit Facilities will be terminated, (iii) to fund the Dowlais Notes Change of Control Offer and (iv) the remainder, if any, for general corporate purposes, which may include, among other things, repayment of debt. See "Use of Proceeds."

Strategic rationale

AAM and Dowlais are leading global tier-one automotive suppliers specializing in driveline and metal forming technologies for internal combustion, electric and hybrid vehicles. The combination of AAM and Dowlais will create a leading global manufacturer with the scale, product portfolio, technology and global diversification required to lead and innovate in a transitioning business environment. The Combined Group is expected to have 48,000 associates and operate in 25 countries over 170 locations.

5

We believe that the Combined Group will benefit from a more diversified business model across both customers and geographies as well as the synergies expected to arise from the combination of AAM and Dowlais. This business will feature a robust cash-generative financial profile, a strong balance sheet, and a more competitive and margin enhancing position than the standalone businesses, enabling continued innovation, growth, and long-term value creation for shareholders as the industry transitions to alternate propulsion technologies.

The Combination will bring together two companies with highly complementary customer bases, geographic footprints, powertrain-agnostic product portfolios and manufacturing operations. It will benefit from an experienced management team and the significant leadership depth present in both organizations.

Leading global driveline and metal-forming supplier with significant size and scale: The Combined Group benefits from greater scale and diversification, leading to enhanced financial and operational resilience. We believe this greater scale enables the business to better adapt to demand fluctuations and macroeconomic events; strengthens relationships with customers and other industry stakeholders; provides a competitive cost base driven by economies of scale; greater sharing of resources for research, development and investment, including electric vehicle transition and new technologies; and increased agility and flexibility in a dynamic, fast-moving industry.

Comprehensive powertrain-agnostic product portfolio with leading technology: The Combination creates an industry-leading portfolio of products across a broad range of automotive segments supporting internal combustion engine, hybrid and electric powertrains. Our leading position in beam axles is complemented by Dowlais' strong position in side-shafts, and the two together position us to better compete for business with our existing and new customers. The metal forming and powder metallurgy product groups provide vertical integration capabilities as well as enhanced diversification with attractive and growing non-automotive industrial end markets. The Combined Group also benefits from enhanced scale to fund investments in future innovation across its powertrain-agnostic product portfolio.

Diversified customer base with expanded and balanced geographic presence: The Combined Group is positioned to take advantage of global markets by serving a wide range of vehicles with a well-diversified and complementary customer base. As adjusted for the Combination, the top three customers of the Group would account for only 48% of revenue with General Motors, Stellantis and Ford each representing 27%, 11% and 10%, respectively, as compared to approximately 68% of revenue for AAM standalone in the year ended December 31, 2024. Toyota, Volkswagen and Renault-Nissan will be the fourth, fifth and sixth largest customers, each representing 5%, 4% and 3% of sales, respectively. Additionally, the Combined Group is expected to benefit from a more balanced regional presence. AAM's position in pickup trucks and SUVs and Dowlais' position across multiple other vehicle segments globally would create an attractive business portfolio. The combined business will also have a strong foundation to serve the large and growing Chinese vehicle market, in particular with emerging domestic Chinese OEMs that are positioned for global growth, while also remaining favorably exposed to the profitable North American automotive market. As adjusted for the Combination, North America is expected to account for 57% of revenue, while Europe will account for 23%, the Asia-Pacific region will account for 18% and South America will account for the remaining 1% each for the year ended December 31, 2024, including Dowlais' joint venture operations

6

Compelling industrial logic with approximately $300 million of expected synergies: The complementary nature of AAM's and Dowlais' businesses is expected to enable the creation of annual run rate cost synergies of approximately $300 million, expected to be substantially achieved by the end of the third year after consummation of the Combination. We estimate the costs required to achieve our synergy plan are approximately equal to one year of savings. The AAM management team has a proven acquisition track record, having successfully integrated and delivered cost synergy value through the acquisitions of MPG and Tekfor Group. Additionally, the Dowlais management team has demonstrated a proven track record of restructuring resulting in operational improvements.

High margins, with strong earnings accretion, cash flow and balance sheet: The Combined Group's enhanced customer, geographic, and product diversification supports a best-in-class financial profile and greater free cash flow generation relative to our standalone business, with combined revenue of approximately $12 billion (calculated based on the unaudited pro forma financial information for the year ended December 31, 2024 included in the section of this offering memorandum entitled "Unaudited Pro Forma Condensed Combined Financial Information") and combined Adjusted EBITDA margin of approximately 14% (calculated based on AAM's definition of Adjusted EBITDA, the unaudited pro forma financial information for the year ended December 31, 2024 included in the section of this offering memorandum entitled "Unaudited Pro Forma Condensed Combined Financial Information" and certain other financial information of both AAM and Dowlais and assuming the full $300 million of estimated run rate synergies were achieved at the beginning of the period). See Basis of Presentation" regarding "combined" metrics, "Forward-Looking Statements" regarding synergies and "-AAM Holdings Summary Historical and Pro Forma Consolidated Financial Data" for a reconciliation of Adjusted EBITDA and Adjusted EBITDA margins to the most directly comparable GAAP metrics. The Combination could illustratively generate approximately $575 million of annual Adjusted Free Cash Flow when combining AAM historical annual average 2023 and 2024 Adjusted Free Cash Flow of approximately $225 million, Dowlais historical annual average 2023 and 2024 Adjusted Free Cash Flow of approximately $175 million excluding restructuring payments, synergy implementation costs and other items as per AAM's definition of Adjusted Free Cash Flow, and assuming full realization of annual run rate synergy potential of $300 million, and after giving effect to illustrative incremental interest expense and taxes of approximately $125 million. This illustrative free cash flow generation would represent approximately 5% of combined sales. In addition, we took a prudent approach to funding this acquisition through a combination of both cash and shares.

AAM's capital allocation policy will prioritize debt repayment while supporting organic growth until our net leverage ratio (defined as net debt (defined as total debt, less cash and cash equivalents) divided by the trailing 12 months of Adjusted EBITDA) is below 2.5 times, at which point AAM would be open to a more balanced capital allocation strategy, while continuing to target further net leverage reductions.

Competitive strengths

Sustained operational excellence and focus on cost management

We deliver operational excellence by leveraging our global standards, policies and best practices across all disciplines through the use of the AAM Operating System, which includes, among other elements, our S4 (S-to-the-fourth) safety system, Q4 (Q-to-the-fourth) quality system and E4 (E-to-the-fourth) energy and environmental sustainability system.

Our business is vertically integrated to reduce cost and mitigate risk. Our Metal Forming segment, in addition to supplying component parts to many external customers, is a key supplier to our Driveline segment, helping to ensure continuity of supply and high level of quality for parts to our largest manufacturing facilities.

During 2024, we launched 11 programs across our business units for our customers including GM, Stellantis, Mercedes-AMG and Audi. In the first half of 2025, we also announced a significant new business win with Volkswagen's Scout brand for their electrified Traveler SUV and Terra pickup truck.

Delivering exceptional quality, which is the foundation of our products' durability and reliability

AAM's Q4 internal quality assurance system drives continuous improvement to meet and exceed the growing expectations of our OEM customers.

In 2024, five of our global facilities received the GM Supplier Quality Excellence Award for outstanding quality performance during the 2023 performance year.

AAM was also recognized in 2024 for quality by several other customers including the Paccar 10 PPM Quality Award at our Hausach, Germany facility, the Ashok Leyland Certificate of Appreciation for Consistent Quality Performance at our Chennai, India facility and Pune, India facility, the Chery Excellent Supplier Award at our Changshu, China facility and the Jaguar Land Rover Quality Award at our Eisenach, Germany facility.

For the 2024 performance year, AAM was recognized by Ford with the Q1 Quality Award at our Bluffton, Indiana facility and our Pyeongtaek, South Korea facility.

Achieving technology leadership by delivering innovative products that enhance our product portfolio while increasing our total global served market

We are focused on securing and enhancing our core business, as the cash flows generated from our existing programs and products contribute to our research and development ("R&D") investments that are expected to bring the future of the automotive industry faster. We leverage the extensive capabilities of our Driveline and Metal Forming business units to serve the future platforms of our global OEM customers. Our e-beam axle design is well-positioned to compete in the electrified powertrains of the future, exemplified by the recent announcement of the Scout Terra and Scout Traveler programs, and showcase the innovative product design approach our customers rely upon. In addition, we are the named supplier for the Scout brand's front electric drive unit, showcasing our ability to bring our diverse product offerings together to support global OEMs and provide an integrated solution for their propulsion needs at a compelling value.

Our strategy

Securing and enhancing our core business

AAM has established a high-efficiency product portfolio that is designed to improve axle efficiency and fuel economy through innovative product design technologies. As our customers focus on reducing weight through the use of aluminum and other lightweighting alternatives, AAM is well positioned to offer innovative, industry leading solutions. Our portfolio includes high-efficiency axles, aluminum axles and AWD applications. AAM's lightweight axle technology features an innovative design, which offers significant mass reduction and increased fuel economy and efficiency that is scalable across multiple applications without the loss of performance or power.

We have secured our core business as we have been awarded multiple next-generation full-size pickup truck front and rear axle programs, sport utility vehicle programs and crossover vehicle programs with OEM customers, and by also being named as the axle supplier for GM's Chevrolet Colorado and GMC Canyon mid-size pickup trucks. Collectively, these awards secure a large portion of our revenues through 2030 and beyond. In addition, we believe we are favorably positioned for resurging quoting activity for ICE and hybrid powertrain programs as a result of slowing electric vehicle penetration in North America.

Our Metal Forming segment represents the largest automotive forging operation in the world, and provides engine, transmission, driveline and safety-critical components for light, commercial and industrial vehicles. We have developed advanced forging and machining process technologies to manufacture lightweight, highly precise and power-dense products. During 2024, our Metal Forming segment was awarded multiple internal combustion engine vehicle component programs by global OEMs.

We continue to evaluate our existing product portfolio for areas that are not core to our business in order to enhance AAM's ability to compete globally while remaining cost competitive. During 2024, we entered into a definitive agreement to sell our commercial vehicle axle business and related assets in India (AAM India Manufacturing Corporation Pvt., Ltd.) for a sales price of $65 million, subject to certain customary adjustments at closing. The sale closed on July 1, 2025. In addition, during the first quarter of 2025 we exited our 50% ownership of Hefei AAM and Liuzhou AAM in China and collected $30 million in proceeds as a result.

Also during 2024, AAM announced a new business award to supply components to a global OEM for its new modular platform that will support multiple propulsion systems, as well as new business awards to supply various electric vehicle components for multiple OEM customers, including electric drive gears for a European OEM.

We are focused on increasing our presence in global markets to support our customers' platforms

As our customers design their products for global markets, they will continue to require global support from their suppliers. For this reason, it is critical that we maintain a global presence in these markets in order to remain competitive for new contracts. To expand our global capabilities, we have established business offices and engineering centers of excellence in research and development, product testing and prototype development in North America, Europe and Asia.

We continue to evaluate and consider strategic opportunities that will complement our core strengths, supplement our diversification strategies and increase our presence in global markets, while providing future, profitable growth prospects. On January 29, 2025, we announced that we had reached an agreement with the Board of Directors of Dowlais Group plc (Dowlais) on the terms of a recommended cash and share offer to be made by AAM to acquire the entire issued and to be issued ordinary share capital of Dowlais for approximately $1.44 billion in cash and AAM shares. Our pending combination with Dowlais is a key step in achieving our goals of customer, product and geographic diversification.

Financing related to the combination

AAM Holdings expects to fund the cash portion of the consideration in connection with the Combination and related transactions costs using $843.0 million principal amount of borrowings under an incremental Tranche C Term Facility (as defined herein) under the Credit Agreement, the proceeds from this issuance of notes and cash on hand. See "Use of Proceeds."

This offering of notes is not contingent upon the completion of the Combination. As a result, we cannot assure you that the Combination will be consummated or, if consummated, that it will be consummated for the price, within the timeframe or on the terms and with the anticipated benefits we currently expect. However, in the event the Combination is not completed, the entire principal amount of secured notes and $600 million aggregate principal amount of unsecured notes, will be subject to a special mandatory redemption. See "Description of Secured Notes-Escrow of proceeds; Special Mandatory Redemption" and "Description of Unsecured Notes-Escrow of proceeds; Special Mandatory Redemption."

Credit agreement amendment

AAM Holdings and AAM Inc. are parties to an amended and restated credit agreement that was entered into on March 11, 2022 and has been subsequently amended by the Second Amendment, as defined below (as may be amended from time to time, the "Credit Agreement") which provides for a term loan A facility (the "Term Loan A Facility"), term loan B facility (the "Term Loan B Facility"), the incremental tranche C term facility (the "Tranche C Term Facility") and a multi-currency revolving credit facility (the "Revolving Credit Facility").

On February 24, 2025, AAM Holdings and AAM Inc. entered into the Second Amendment to the Amended and Restated Credit Facility and the Incremental Facility Agreement (the "Second Amendment"). The Second Amendment, among other things, (i) increased the maximum under the Revolving Credit Facility from $925.0 million to $1,495.0 million, effective upon closing of the Combination, (ii) provided for an $843.0 million incremental Tranche C Term Facility in connection with the Combination and (iii) extended the maturity of the Revolving Credit Facility and Term Loan A Facility for five years from the date of the Second Amendment, resetting for another five years upon the closing of the Combination.

Bridge facilities

On January 29, 2025, in connection with the announcement of the Combination, AAM Holdings and AAM Inc. entered into a First Lien Bridge Credit Agreement (the "First Lien Bridge Facility"), and a Second Lien Bridge Credit Agreement (the "Second Lien Bridge Facility" and together with the First Lien Bridge Facility, the "Bridge Facilities").

Additionally, in connection with entry into the Second Amendment, on February 24, 2025, AAM Holdings and AAM Inc. entered into (i) an Amended and Restated First Lien Bridge Credit Agreement which will provide us with a $843.0 million interim loan facility in connection with the Combination (the "Amended and Restated First Lien Bridge Credit Agreement") and (ii) an Amended and Restated Second Lien Bridge Credit Agreement which will provide us with a $500.0 million interim loan facility in connection with the Combination (the "Amended and Restated Second Lien Bridge Credit Agreement", and together with the Amended and Restated First Lien Bridge Credit Agreement, the "Bridge Credit Agreements").

The amounts available under the Bridge Credit Agreements will be reduced by, among other things, the net proceeds we receive from this offering. We currently expect that the net proceeds of this offering, along with borrowings under our Credit Agreement and cash on hand, will be sufficient to fund the cash consideration of the Combination. While not anticipated, if and to the extent we do not receive sufficient net proceeds in this offering, we may be required to borrow additional amounts under our Credit Agreement or under the Bridge Credit Agreements in order to finance the Combination. The funding of the Bridge Credit Agreements is contingent upon the satisfaction of customary conditions the consummation of the Combination.

12

Certain of the initial purchasers are lenders under our Credit Agreement. In addition, certain of the initial purchasers and/or their affiliates provided the committed financing under the Bridge Credit Agreements. See "Plan of Distribution."

Transactions related to the outstanding debt of Dowlais

Repayment of the Dowlais Credit Facilities

In connection with the closing of the Combination, we intend to repay in full all outstanding borrowings of Dowlais under its £100 million and €100 million term loans as well as its £350 million, $660 million and €450 million revolving credit facilities (collectively, the "Dowlais Credit Facilities") and to pay related fees, expenses and premiums. Following such repayment, the Dowlais Credit Facilities will be terminated. As of June 30, 2025, the aggregate principal amount outstanding under the Dowlais Credit Facilities was $1.29 billion (based on the exchange rate included in this offering memorandum. See "Basis of Presentation").

Change of control offer for the Dowlais Notes

Following the closing of the Combination, AAM will be required to make a change of control offer for the outstanding Dowlais Notes (the "Dowlais Notes Change of Control Offer"). Pursuant to the terms of the note purchase agreement governing the Dowlais Notes (the "Note Purchase Agreement"), the consummation of the Combination will constitute a "Change of Control." Under the terms of the Note Purchase Agreement, the holders of the Dowlais Notes will have the right to require Dowlais to repurchase all of the holders' Dowlais Notes at a purchase price equal to 100% of the principal amount of the applicable Dowlais Notes, plus accrued and unpaid interest thereon to the repurchase date. Pursuant to the terms of the Note Purchase Agreement, the Dowlais Notes Change of Control Offer will be made within 15 business days after the closing of the Combination and the repurchase date will be not less than 30 days and not more than 60 days after the date on which we make the Dowlais Notes Change of Control Offer to the holders of the Dowlais Notes.

As of June 30, 2025, Dowlais had the following outstanding notes: (i) 5.77%. Series A Senior Notes due 2029, having the aggregate outstanding principal amount of $145,000,000, (ii) 5.97% Series B Senior Notes due 2031, having the aggregate outstanding principal amount of $48,000,000, (iii) 6.07% Series C Senior Notes due 2032, having the aggregate outstanding principal amount of $100,000,000, (iv) 6.26% Series D Senior Notes due 2034, having the aggregate outstanding principal amount of $102,000,000 and (v) 6.36% Series E Senior Notes due 2036, having the aggregate outstanding principal amount of $105,000,000, in each case, issued by GKN Industries Limited, a subsidiary of Dowlais, and guaranteed by Dowlais and certain of its subsidiaries (collectively, the "Dowlais Notes"). As of June 30, 2025, Dowlais had $500 million of Dowlais Notes outstanding.

The decision as to whether to tender the Dowlais Notes in the Dowlais Notes Change of Control Offer will be made by each holder of Dowlais Notes at their discretion and for this reason, we cannot accurately predict the outcome of the Dowlais Notes Change of Control Offer. Any remaining proceeds not used to fund the Dowlais Notes Change of Control Offer will be used for general corporate purposes, which may include, among other things, repayment of debt.

Transfer of U.S. subsidiaries of Dowlais to AAM and the related disposal offer

Following the closing of the Combination, Dowlais will consider selling to AAM all U.S. subsidiaries of Dowlais at fair value of the subsidiaries (the "Disposal"). AAM expects to fund the Disposal with cash on hand and, if needed, borrowings under the Revolving Credit Facility.

13

In accordance with the terms of the Notes Purchase Agreement, if this transaction occurs, Dowlais will be required to make a disposal offer (the "Disposal Offer") to the holders of the Dowlais Notes to repurchase the Dowlais Notes with the net proceeds (defined as cash consideration for the Disposal less payments of certain expenses, taxes and pension contributions) from the Disposal, at a purchase price equal to 100% of the principal amount of the applicable Dowlais Notes, plus accrued and unpaid interest thereon to the repurchase date. The Disposal Offer would be made concurrently with the Dowlais Notes Change of Control Offer and Dowlais would repurchase any Dowlais Notes tendered pursuant to the Disposal Offer concurrently with the Dowlais Notes tendered for repurchase in connection with the Dowlais Notes Change of Control Offer.

The decision as to whether to tender the Dowlais Notes in the Disposal Offer will be made by each holder of Dowlais Notes at their discretion and for this reason, we cannot accurately predict the outcome of the Disposal Offer.

The completion of the Dowlais Notes Change of Control Offer or the Disposal Offer will not be a condition to closing of the Combination.

The notes will be structurally subordinated to any Dowlais Notes that remain outstanding following completion of the Dowlais Notes Change of Control Offer and the Disposal Offer. See "Risk Factors-If the Dowlais Notes Change of Control Offer and the Disposal Offer are not fully accepted, the notes will be structurally subordinated to the Dowlais Notes."

Certain of the initial purchasers or their affiliates may be lenders under the Dowlais Credit Facilities or owners of the Dowlais Notes, in which case such initial purchasers or their affiliates may receive a portion of the net proceeds of this offering in connection with the repayment in full or in part of amounts outstanding under the Dowlais Credit Facilities or the Dowlais Notes following the Dowlais Notes Change of Control Offer (to the extent any such notes are tendered in the Dowlais Notes Change of Control Offer). See "Plan of Distribution."

Escrow arrangements

The issuance of the notes may occur prior to the date on which a copy of the Court Order sanctioning the Scheme is duly filed on behalf of Dowlais with the Registrar of Companies in England and Wales and the Scheme becomes effective in accordance with section 899 of the Companies Act 2006 (the "Scheme Effective Date"). If so, on the issue date, pending the occurrence of the Scheme Effective Date, AAM Inc. will deposit into segregated escrow accounts for each of the secured notes and the unsecured notes (i) an amount of cash equal to (1) in the case of the escrow account for the secured notes, the gross proceeds from the sale of such series of secured notes in this offering and (2) in the case of the escrow account for the unsecured notes, the gross proceeds from $600 million aggregate principal amount of unsecured notes and (ii) an amount of cash equal to (1) in the case of the escrow account for the secured notes, the amount of interest that would accrue on the secured notes from and including the issue date to, but excluding October 31, 2025 and (2) in the case of the escrow account for the unsecured notes, the amount of interest that would accrue on $600 million aggregate principal amount of unsecured from and including the issue date to, but excluding October 31, 2025. Prior to the release of the proceeds from escrow, the respective escrow accounts and the funds therein will be pledged on a first- priority basis as collateral for the benefit of holders of the applicable series of notes. If neither the Escrow Release Date nor a special mandatory redemption has previously occurred, no later than three business days prior to the end of each month (commencing October 31, 2025) and ending with the Escrow Outside Date (as defined herein), AAM Inc. will deposit (or cause to be deposited) in each escrow account an amount of additional cash equal to the interest that would accrue on the applicable series of notes from and including the last day of the then-current month to, but excluding, the last day of the next succeeding month.

14

Upon delivery to the escrow agent, the Secured Notes Trustee (as defined herein) and the Unsecured Notes Trustee (as defined herein) of an officer's certificate instructing the escrow agent to release the escrowed funds and certifying that (1) all conditions precedent to the Combination have been satisfied or waived in accordance with the terms of the Scheme documents as in effect on the date of this offering memorandum, without amendment or waiver in a manner that would be materially adverse to the holders of the secured notes, other than (A) the payment of the consideration to be paid for the Combination for which the escrowed funds are required (but subject to the payment of such consideration using the escrowed funds), and (B) such other conditions precedent that by their nature are to be satisfied at the time of completion of the Combination (but subject to the satisfaction or waiver of such conditions); (2) the Scheme Effective Date has occurred or substantially concurrently with the release of the escrowed funds will occur and (3) no Default or Event of Default has occurred and is continuing at the time of, or immediately after giving effect to, the Combination (clauses (1), (2) and (3), collectively, the "Escrow Conditions"), the escrowed funds will be released to AAM Inc. See "Description of Secured Notes-Escrow of proceeds; Special Mandatory Redemption" and "Description of Unsecured Notes-Escrow of proceeds; Special Mandatory Redemption." In addition, if the Escrow Conditions are satisfied, a deferred discount will be paid to the initial purchasers in connection with this offering.

If the Escrow Conditions are not satisfied on or prior to the later of (i) June 29, 2026 and (ii) such later date (if any) as AAM Holdings and Dowlais may agree to extend the "Long Stop Date" (as defined in the Co-operation Agreement in accordance with the Co-operation Agreement) (such later date, the "Escrow Outside Date"), or such earlier date if AAM Inc. determines in its sole discretion that the Escrow Conditions cannot be satisfied or AAM Inc. notifies the escrow agent, the Secured Notes Trustee and the Unsecured Notes Trustee in writing that AAM Inc. will not pursue the consummation of the Combination and/or the Scheme lapses or is terminated (such earliest date, the "Special Termination Date"), AAM Inc. will be required to redeem all of the outstanding secured notes and $600 million aggregate principal amount of the unsecured notes on the third business day thereafter at a price equal to 100% of the initial issue price of such notes, together with accrued and unpaid interest on such notes, if any, to, but excluding, the date of such special mandatory redemption. Escrowed funds would be released and applied to pay for any such redemption. See "Description of Secured Notes-Escrow of proceeds; Special Mandatory Redemption" and "Description of Unsecured Notes-Escrow of proceeds; Special Mandatory Redemption."

If the issuance of the notes occurs on or after the Scheme Effective Date, none of the escrow provisions described in this offering memorandum will be applicable, no proceeds of this offering will be deposited into the escrow accounts and all such proceeds will be provided to AAM Inc. on the issue date for use as described under "Use of Proceeds." We may elect to increase the amount of unsecured notes being offered hereby in order to fund the redemption or other repayment in full of our outstanding unsecured 6.50% Senior Notes due 2027 and related fees and expenses, in which case we would expect to increase the offering size of the unsecured notes by approximately $500 million to $1.1 billion. Even if more than $600 million aggregate principal amount of unsecured notes is issued in this offering, the special mandatory redemption provisions described herein will only apply to $600 million aggregate principal amount of unsecured notes and the amount of proceeds from the unsecured notes that is deposited into escrow upon issuance will remain equal to the gross proceeds of $600 million aggregate principal amount of unsecured notes. See "Risk Factors-Risks Related to the Unsecured Notes-If we issue more than $600 million aggregate principal amount of unsecured notes in this offering, the special mandatory redemption provisions will only apply to $600 million aggregate principal amount of unsecured notes and will not apply to the entire aggregate principal amount of the unsecured notes." and "Description of Notes-Escrow of Proceeds; Special Mandatory Redemption."

References in this offering memorandum to the "Escrow Release Date" refer to (i) the issue date, if this offering closes on or after the Scheme Effective Date and (ii) otherwise, the date of release of the escrowed notes proceeds from escrow.

AAM Holdings summary historical and pro forma consolidated financial data

The summary consolidated financial data of AAM Holdings for each of the years ended December 31, 2024, 2023 and 2022 and as of December 31, 2024 and 2023 have been derived from our audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024, which is incorporated by reference herein. The balance sheet data of AAM Holdings presented as of December 31, 2022 has been derived from AAM Holdings' audited consolidated financial statements not incorporated by reference herein.

The summary consolidated financial data for AAM Holdings for the six months ended June 30, 2025 and 2024 have been derived from our unaudited consolidated financial statements incorporated by reference in this offering memorandum. The balance sheet data of AAM Holdings presented as of June 30, 2024 has been derived from AAM Holdings' unaudited consolidated financial statements not incorporated by reference herein. The unaudited consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, include all adjustments, consisting of normal recurring adjustments, necessary for a fair statement of the results for those periods.

The unaudited pro forma combined information for the twelve months ended June 30, 2025 gives effect to the Combination as if it had occurred on January 1, 2024. The unaudited pro forma condensed combined financial statements are based on the historical consolidated financial statements of AAM Holdings and Dowlais. The unaudited pro forma condensed combined financial statements reflect pro forma adjustments for: (i) reclassifications resulting from differences in AAM and Dowlais' accounting policies or changes to financial statement presentation to conform the financial statements of AAM and Dowlais; (ii) adjustments to Dowlais financial statements for differences in accounting treatment and/or financial statement presentation between IFRS and GAAP; and (iii) to reflect the Combination and estimated transaction and financing costs anticipated to be incurred in connection with the Combination. The unaudited pro forma condensed combined statement of income for the twelve months ended June 30, 2025 has been calculated by subtracting the unaudited pro forma condensed consolidated statement of income data for the six months ended six months ended June 30, 2024 from the unaudited pro forma condensed combined statement of income for the twelve months ended December 31, 2024, and adding the unaudited pro forma condensed combined statement of income data for the six months ended June 30, 2025. The summary unaudited pro forma consolidated financial information is presented for illustrative purposes only and is not necessarily indicative of what the actual consolidated results of operations would have been had the Combination and related financings been completed on the date indicated or what such results would be for future periods. The summary historical and unaudited pro forma consolidated financial data presented below should be read in conjunction with the other information included or incorporated by reference herein, including the information included under the headings "The Transactions," "Dowlais Summary Consolidated Financial Data," "Capitalization," "Unaudited Pro Forma Condensed Combined Financial Statements," "Management's Discussion and Analysis of Financial Condition and Results of Operations of Dowlais" as well as "Management's Discussion and Analysis of Financial Condition and Results of Operations" in AAM Holdings' Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2025, which are incorporated by reference herein, and the audited consolidated financial statements and the unaudited consolidated financial statements and related notes thereto included or incorporated by reference in this offering memorandum.

(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, gains or losses on the derivative associated with the Combination, gains or losses on equity securities, pension curtailment and settlement charges, impairment charges 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 banking institutions routinely use EBITDA and Adjusted EBITDA, together with other measures, to measure our operating performance relative to other Tier 1 automotive suppliers and to assess the relative mix of Adjusted EBITDA by segment. We also believe that Adjusted EBITDA is a meaningful measure as it is used for operational planning and decision-making purposes. EBITDA and Adjusted EBITDA are also key metrics used in our calculation of incentive compensation. These non-GAAP financial measures are not and should not be considered a substitute for, and should not be considered in isolation from, any GAAP measure. Additionally, non-GAAP financial measures as presented by us may not be comparable to similarly titled measures reported by other companies.

(a) We define Free Cash Flow to be net cash provided by operating activities less capital expenditures net of proceeds from the sale of property, plant and equipment. Adjusted Free Cash Flow is defined as Free Cash Flow excluding the impact of cash payments for restructuring and acquisition-related costs and cash payments related to the Malvern fire, including payments for capital expenditures, net of recoveries. We believe Free Cash Flow and Adjusted Free Cash Flow are meaningful measures as they are commonly utilized by management and investors to assess our ability to generate cash flow from business operations to repay debt and return capital to our stockholders. Free Cash Flow and Adjusted Free Cash Flow are also key metrics used in our calculation of incentive compensation. These non-GAAP financial measures are not and should not be considered a substitute for, and should not be considered in isolation from, any GAAP measure. Additionally, non-GAAP financial measures as presented by us may not be comparable to similarly titled measures reported by other companies.

(1) On January 29, 2025, in connection with the announcement of the Combination, AAM Holdings and AAM Inc. entered into the First Lien Bridge Facility and the Second Lien Bridge Facility. As of June 30, 2025, no amounts were outstanding under the Bridge Facilities. We currently expect that the net proceeds of this offering, along with borrowings under our Credit Agreement and cash on hand, will be sufficient to fund the cash consideration of the Combination. While not anticipated, if and to the extent we do not receive sufficient net proceeds in this offering, we may be required to borrow additional amounts under our Credit Agreement or under the Bridge Credit Agreements in order to finance the Combination.

(2) As of June 30, 2025, $897.1 million was available under the Revolving Credit Facility, which reflected a reduction of $27.9 million for standby letters of credit issued against the facility. As of June 30, 2025, after giving effect to the Transactions and the application of proceeds as described in "Use of Proceeds," we would have had $1.5 billion available under the Revolving Credit Facility, which would reflect a reduction of $27.9 million for standby letters of credit issued against the facility.

(3) Pursuant to the terms of the Note Purchase Agreement, the Dowlais Notes Change of Control Offer will be made within 15 business days after the closing of the Combination and the repurchase date will be not less than 30 days and not more than 60 days after the date on which we make the Dowlais Notes Change of Control Offer to the holders of the Dowlais Notes. Pursuant to the terms of the Notes Purchase Agreement, if the Disposal occurs, Dowlais will be required to make the Disposal Offer to the holders of the Dowlais Notes to repurchase the Dowlais Notes with the net proceeds from the Disposal. If the Disposal occurs, Dowlais intends to make the Disposal Offer concurrently with the Dowlais Notes Change of Control Offer and repurchase any Dowlais Notes tendered pursuant to the Disposal Offer concurrently with the Dowlais Notes tendered for repurchase in connection with the Dowlais Notes Change of Control Offer. As of June 30, 2025, Dowlais had $500 million of Dowlais Notes outstanding and the fair value of the Dowlais Notes was $585 million. The decision as to whether to tender the Dowlais Notes in the Dowlais Notes Change of Control Offer or the Disposal Offer will be made by each holder of Dowlais Notes at their discretion and for this reason, we cannot accurately predict the outcome of the Dowlais Notes Change of Control Offer or the Disposal Offer. Any remaining proceeds not used to fund the Dowlais Notes Change of Control Offer will be used for general corporate purposes, which may include, among other things, repayment of debt. For purposes of the table above, we have assumed that none of the Dowlais Notes will be tendered in the Dowlais Notes Change of Control Offer or the Disposal Offer, and that none of the sources of funds will be used to fund the Dowlais Notes Change of Control Offer (and, accordingly, all such funds that may be used to fund the Dowlais Notes Change of Control Offer have been added to Cash and cash equivalents in the Pro Forma As Adjusted column). See "Summary-Transactions Related to the Outstanding Debt of Dowlais."

Business activities

Dowlais develops and delivers precisely engineered solutions for the automotive industry through its two high-technology engineering businesses: GKN Automotive and GKN Powder Metallurgy.

GKN automotive

GKN Automotive is a global leader in the development and production of sideshafts, proposhafts, AWD systems and advanced differentials and a trusted partner to automotive OEMs globally. Its products drive the wheels of light vehicles around the world and it has been a pioneer in the development of eDrive systems, remaining at the forefront of electric vehicle powertrain technology. While its core Driveline product group works with all types of powertrains, including electric, hybrid and traditional engines, its ePowertrain product group has potential for growth with new EV platforms. As more vehicles adopt electric powertrains, demand for larger joints and higher installation rates present a growth opportunity. Additionally, its strong market position in China, via joint venture SDS with local partner HUAYU Automotive Systems Co. Ltd ("HASCO"), gives GKN Automotive a unique advantage in expanding alongside the fast-growing Chinese OEM Market. SDS is the leading supplier of driveline products to the Chinese market, supplying 9 of the top 10 OEMs in China, with ten manufacturing facilities located in the country. SDS' share with local Chinese OEMs continues to grow. As of June 30, 2025, Dowlais' has received £178 million in cumulative dividends from JV operations since 2023.

GKN Automotive operates 48 manufacturing locations across Europe, the Americas, Asia Pacific and China, as well as five technology and innovation centers, with around 24,000 employees globally (including joint ventures).

GKN powder metallurgy

GKN Powder Metallurgy is a global leader in the production of sintered metal products for the automotive and industrial sectors and a world-class manufacturer of atomised metal powders. Its world-class engineering expertise and sustainable technology enables the design and production of parts with complex geometries, higher densities and improved physical properties.

Strategic goals

The Dowlais Group's purpose is engineering transformation for a sustainable world. This forms part of the Dowlais Group's wider strategic framework within which its purpose, its strategy and its values of agility, accountability and ambition are all aligned.

28

The Dowlais Group's overall strategy is focused on three pillars:

· Lead: The Dowlais Group aims to lead in both market position and financial performance by consistently prioritising operational excellence. This is achieved through implementing best in class manufacturing, commercial and procurement processes, as well as maintaining strict discipline in managing working capital.
· Transform: Continuous improvement and agility are central to the Dowlais Group's operations. It is digitising and optimising manufacturing processes, improving their production footprint to enhance competitiveness, and driving innovation in its product portfolio to support the transition to electrified mobility.
· Accelerate: The Dowlais Group is positioned for organic growth while remaining open to value- accretive M&A opportunities at the appropriate time. Its approach is prudent and disciplined, targeting opportunities that align with its portfolio strategy and deliver shareholder value.

Lead

The Dowlais Group continues to build on its position as a portfolio of market-leading, high- technology engineering businesses, with a clear focus on delivering industry-leading financial performance and shareholder value. The Dowlais Group delivered a 0.1% adjusted operating margin expansion in 2024, despite a 6.4% year-on-year decline in adjusted revenue, demonstrating resilience and operational agility in a volatile market environment. In Powder Metallurgy, 56% of new business wins were attributed to EV or propulsion-agnostic products, demonstrating the business's alignment with evolving market demands and its strategic focus on supporting the electrification transition.

Transform

The Dowlais Group continues to take a disciplined approach to investing in its portfolio, with a focus on transitioning to a powertrain-agnostic business model that is resilient to global market fluctuations and well-positioned to deliver sustainable, profitable growth and cash generation. In 2024, the Dowlais Group made the decision to right size engineering investment in the business' eDrive systems product line to optimize capital allocation, with gross engineering spend on the ePowertrain product line totaling £95.8 million, expected to reduce to approximately £60 million by the end of 2025. This proactive step reflects its strategy of balancing disciplined investment with long-term profitability, ensuring that it is better positions to navigate the increasing volatility in the battery electric vehicle market.

In Powder Metallurgy, the order book grew by 2% in 2024, with 56% of new business wins attributed to EV or propulsion-agnostic products, reinforcing its strategic focus on supporting the electrification transition. The Dowlais Group has continued to expand production capacity in Mexico and relocating production from its Mosel plant in Germany to its newly opened facility in Hungary, enhancing regional competitiveness and operational efficiency.

Accelerate

At the start of 2024, GKN Powder Metallurgy established a new leadership team and developed a clear strategic and commercial plan to accelerate a range of options including a potential sale. The Dowlais Group also disposed of its entire interest in its GKN Hydrogen business to Langley Holdings plc, eliminating future cash losses associated with the funding of the Hydrogen operations. The Combination with AAM is expected to accelerate the realization of shareholder value through the establishment of a global automotive supplier with market-leading capabilities, better positioned together to navigate both the short-term challenges and long-term market dynamics in the automotive sector.

29

Regulatory environment

The Dowlais Group is subject to regulation from national and international regulatory authorities concerning, among other things: (i) working conditions of employees, in particular in connection with environmental hazards in the workplace; (ii) restrictions arising from economic sanctions, export controls and customs; (iii) product liability claims, in particular in connection with products supplied to global production programs or to consumer end-markets; and (iv) compliance with anti- bribery, anti-corruption and anti-money laundering legislation.

In order to ensure compliance with these regulations, the Dowlais Group regularly monitors existing legal and regulatory matters, both at the group-wide and operating segment levels. The Dowlais Group has a robust control framework in place in order to identify and assess principal risks, underpinned by comprehensive corporate governance and compliance procedures which are periodically reviewed and updated as needed, in line with best practice. Furthermore, the Dowlais Group also maintains insurance coverage for the risks associated with the operations of its businesses, and conducts diligence before purchasing strategic and value enhancing targets to ensure compliance with applicable regulations. The Dowlais Group's businesses have received certification in respect of quality management, environmental management and health and safety procedures from the International Organisation for Standardisation.

Environmental, tax and health and safety regulations

The Dowlais Group operates global facilities that are subject to a broad array of environmental laws and regulations relating to pollution, the health and safety of employees, protection of the public, protection of the environment, the storage and handling of hazardous substances and waste materials and the clean-up of contaminated properties. It is the policy of the Dowlais Group to comply with all relevant laws and regulations. The Dowlais Group actively manages these risks through regular compliance and performance improvement assessments and key performance indicators and the engagement of competent health, safety and environmental coordinators at each of its sites. However, violations of applicable laws and regulations, in particular provisions of environmental and health and safety laws, or changes in such laws and regulations (such as the imposition of more stringent standards for discharges into the environment), could result in litigation and damage to the reputation of the Dowlais Group as above, temporary or permanent restrictions on the operations of the facilities of the Dowlais Group, damages, fines, clean-up costs or other civil or criminal sanctions and/or increased costs of compliance (including capital expenditures).

As an organization with global operations, the Dowlais Group will conduct business in countries subject to complex tax rules, which may be interpreted in different ways. Changes in tax law could result in higher tax expense and payments.

The nature of the Dowlais Group's operating activities exposes the Dowlais Group to a range of health and safety risks if such operations are not properly managed and conducted. Dowlais' employees work in environments where maintaining the highest standards of operational health and safety is critical.

Product liability

As a supplier to major vehicle manufacturers and other customers, it is imperative that Dowlais' products are safe to use and meet quality requirements. A defect in the design or manufacturing process, a failure of controls, or the inadequate performance of Dowlais' suppliers could result in Dowlais supplying products that are unsafe or of inadequate quality. Many of Dowlais' automotive products are considered safety critical and are the subject of vehicle safety and industry regulations.

30

Anti-corruption and sanction regulation

Conducting business on a worldwide basis requires the Dowlais Group to comply with anti- corruption laws and regulations such as the US Foreign Corrupt Practices Act of 1977 and the UK Bribery Act 2010. Additionally, as a result of conducting business in foreign countries, the Dowlais Group will be exposed to a risk of violating anti-corruption laws and sanctions regulations applicable in those countries where it, its partners or agents operate.

While the Dowlais Group has policies and procedures designed to assist its compliance with applicable anti-corruption laws and sanctions regulations, it seeks to continuously improve its systems of internal controls, to remedy any weaknesses that are identified through appropriate corrective action depending on the circumstances, including additional training, improvement of internal controls and oversight and deployment of additional resources. The Dowlais Group also takes appropriate action in case of any breach of the Dowlais Group's rules and procedures which might include disciplinary measures, suspensions of employees and ultimately termination of such employees.

Governmental, legal or arbitration proceedings

In the ordinary course of its business, Dowlais may, at any given time, be involved in various inquiries, administrative proceedings and litigation relation to environmental and safety matters, personal injury, product liability, labor and employment, contracts, sale of property, intellectual property, tax, and other matters, some of which may allege substantial monetary damages. These matters are managed internally by the Dowlais Group and, where appropriate, may involve the assistance of external advisers. Assessments of lawsuits and claims can involve a series of complex judgments about future events, can rely heavily on estimates and assumptions, and are otherwise subject to significant uncertainties. As a result, there can be no certainty that the Dowlais Group will not ultimately incur charges in excess of presently recorded liabilities. The inherent uncertainties involved in pending or threatened legal matters, some of which are beyond the Dowlais Group's control, and the large or indeterminate damages sought in some of these matters are such that an adverse ruling, settlement, unfavorable development or increase in accruals with respect to these matters could result in future charges that could be material to the Dowlais Group's result of operations or cash flows in any particular reporting period.

Management's discussion and analysis of financial condition and results of operations of Dowlais

Introduction

The following discussion and analysis should be read in conjunction with the financial information of Dowlais Group plc set out in the section of this offering memorandum entitled "Index to Dowlais Consolidated Financial Statements". The financial information included in this section has been extracted without material adjustment from the financial information in the section of this offering memorandum entitled "Index to Dowlais Consolidated Financial Statements" or has been extracted without material adjustment from the Dowlais Group's accounting records, which formed the underlying basis of the financial information referred to in the financial information of the Dowlais Group set out in the section of this offering memorandum entitled "Index to Dowlais Consolidated Financial Statements."

The Dowlais Group's consolidated financial statements were historically prepared in accordance with IFRS whereas AAM's consolidated financial statements were historically and are expected to continue to be prepared in accordance with U.S. GAAP. U.S. GAAP differs from IFRS in a number of significant respects. AAM has not prepared, and does not currently intend to prepare, its financial statements or the financial statements of the Combined Group in, or reconcile them to, IFRS and hence has not quantified these differences for prospective investors. In making an investment decision, prospective investors must rely on their own examination of the AAM group, the terms of the Combination and the financial information contained in this offering memorandum.

Dowlais is a specialist engineering group focused on the automotive sector, generating growth through a portfolio of transformative and innovative businesses that advance the world's transition to sustainable vehicles. The Dowlais Group comprises of the GKN Automotive and GKN Powder Metallurgy businesses.

GKN Automotive is a global technology and systems engineer which designs, develops, manufactures and integrates an extensive range of driveline technologies, including electric vehicle ("EV") components with 48 manufacturing facilities in 18 countries. While its core Driveline product group works with all types of powertrains, including electric, hybrid, and traditional engines, its ePowertrain product group has potential for growth with new EV platforms. As more vehicles adopt electric powertrains, demand for larger joints and higher installation rates presents a growth opportunity. Additionally, its strong market position in China, via the joint venture SDS with HASCO, gives GKN Automotive a unique advantage in expanding alongside the fast- growing Chinese OEM market.

GKN Powder Metallurgy is a global leader in precision powder metal parts for the automotive and industrial sectors, as well as the production of powder metal. The business has a strong and diversified core portfolio, serving both industrial and automotive markets. It has also developed significant opportunities to generate incremental growth, including expanding into high-potential EV-ready product categories, such as iron powder for LFP batteries and sintered magnets for electric motors. GKN Powder Metallurgy operates globally with 31 manufacturing plants and two technology centers across 11 countries.

GKN Hydrogen formed part of the Dowlais Group, offering reliable and secure hydrogen storage solutions, until its sale on 29 July 2024.

Industry trends

The vast majority of components supplied by GKN Automotive and GKN Powder Metallurgy are for light vehicles, which comprise passenger cars and light trucks weighing up to 6 tons.

Global light vehicle production ("GLVP") in H1 2025 was estimated at 44.9 million units, representing a year-on-year increase of approximately 3.1%. However, excluding China, GLVP declined by 0.7% over the same period. Market conditions remained volatile, particularly due to trade tensions and the imposition of import tariffs by the United States. Tariffs announced by the US administration in April 2025, along with additional measures on imports from Mexico and Canada, disrupted production flows and weighed on the near to medium term outlook for GLVP. In July 2025, the US administration announced a further wave of tariffs targeting imports from the European Union, Canada, Japan and Korea, amongst others, adding to the macroeconomic uncertainty for the remainder of the year.

In H1 2025, regionally, Asia continued to lead global production, with China producing 14.8 million vehicles and the rest of Asia contributing 11.0 million vehicles. EMEA accounted for 9.9 million vehicles, followed by the Americas at 9.2 million vehicles. China had strong momentum in the first half of the year as production grew by 11.7% year-on-year, followed by the rest of Asia where production grew by 3.1%. In contrast, production declined by 3.1% and 2.4% in EMEA and the Americas respectively.

In 2024, GLVP was estimated at 89.5 million units, reflecting a 1.1% decline year-on-year, per S&P Global Mobility. GLVP has faced significant headwinds in recent years. From 2022 to 2023, GLVP grew by approximately 10%, this momentum reversed in 2024 as inventory replenishment neared completion, consumer demand softened due to high interest rates and inflation, and battery electric vehicle ("BEV") penetration slowed amid the withdrawal of government subsidies.

In 2024, Asia remained the largest producer of light vehicles regionally, with China producing 30.1 million vehicles and the rest of Asia 21.6 million vehicles. EMEA produced 19.4 million vehicles, followed by the Americas at 18.4 million vehicles. While China's production grew 3.6% year-on- year, production declined by 4.1%, 4.5% and 1.0% in EMEA, the rest of Asia and the Americas, respectively.

GLVP forecasts have remained volatile throughout the first half of the year. In 2024, volatilities in the global transition to EVs saw significant drops in production volumes across a number of the Dowlais Group's customers' vehicle platforms. This volatility significantly impacted the ePowertrain product group, where high-value content on a small number of vehicle platforms created a significant revenue headwind. While the Dowlais Group remains committed to the transition to BEV, the pace of change is expected to be slower than initially anticipated. As BEV adoption slows, hybrids-both Hybrid Electric Vehicles and Plug-in Hybrid Electric Vehicles-are increasingly being used as transitional technologies. Governments and consumers view hybrids as a compromise that reduce emissions without the charging infrastructure challenges associated with BEVs. The Dowlais Group's powertrain-agnostic products, such as sideshafts and ePowertrain components, are compatible with hybrids, allowing Dowlais to benefit from this transitional phase.

Since March 2025, the U.S. administration has announced several new tariffs, including a 10% universal base tariff, sector-specific tariffs on automotive imports, and additional reciprocal tariffs targeting individual countries. While the reciprocal tariffs have been temporarily paused until July 26, concerns about their potential impact on consumer demand have already led to downward revisions in industry forecasts. However, a subsequent pause in implementation and exemption for USMCA compliant goods helped improve market sentiment.

33

In April, S&P revised its 2025 industry outlook. In March, it had projected GLVP at 89.5 million units, but this was revised down to 87.9 million units in April-a year-over- year decline of 1.7%, or 3.3% when excluding China. The revisions reflect more cautious expectations for North America, where production is forecast to fall by 9.3%, and for Europe, which is expected to decline by 3.1%. Given the ongoing uncertainty around tariffs, forecasts remain volatile, and further revisions appear likely.

As of its latest forecast, S&P now projects 2025 GLVP at 89.9 million units, implying modest year- on-year growth of 0.4%. Excluding China, a decline of 1.3% is anticipated. For H2 2025, S&P forecasts a 2.2% decline in production compared to the same period in 2024, with China expected to contract by 2.4%, a reversal from the strong growth seen in the first half.

Looking further ahead, 2026 forecasts have also been revised downward, with GLVP growth now expected at 1.1%, down from the previously projected 2.0%.

In the medium term, S&P expects GLVP to grow at a CAGR of approximately 1% and reach around 95 million units by 2030.

Recent transactions and events

On February 28, 2023, Melrose Industries PLC ("Melrose") transferred the entire shareholding of GKN Industries Limited and GKN Powder Metallurgy Holdings Limited to Dowlais such that all the related entities became owned directly or indirectly by Dowlais.

On April 20, 2023, Melrose made a distribution to its shareholders of Dowlais shares with one Dowlais share issued for every Melrose share held. Prior to April 20, 2023, the ultimate parent company and controlling party of the Dowlais Group was Melrose Industries PLC, a public company limited by shares and incorporated in England & Wales.

In early 2024 the Dowlais Group started a process to identify suitable investment partners for the Hydrogen business. On July 29, 2024, the Dowlais Group disposed of its entire interest in its GKN Hydrogen business to Langley Holdings plc, for nominal consideration. This disposal aligns with the Dowlais Group's strategy to focus on businesses where it can add most value through operational improvement initiatives while ensuring fair treatment for all stakeholders involved throughout this process.

Further to the announcement on March 21, 2024, the Dowlais Group commenced a share buyback program on April 4, 2024 of its ordinary shares for up to a maximum aggregate consideration of £50 million, of which £32 million was completed as of June 30, 2025 (as noted below, the share buyback program was discontinued). The purpose of the share buyback program was to reduce the Dowlais Group's share capital and therefore the shares purchased under the program have been cancelled. Following the announcement regarding the recommended combination with AAM on January 29, 2025, the Dowlais Group cancelled the share buyback program with immediate effect.

In the last quarter of 2024, the Dowlais Group successfully refinanced part of its term loan debt through the issuance of US$500 million of notes in the US private placement market. The notes have maturities in the range of 5 - 12 years. Following the note issuance, the notes were repaid in full, with the full $400 million of the term loan debt having been repaid as of June 30, 2025. Post refinancing, the Dowlais Group continues to be funded through two core banking facilities comprised of a multi-currency revolving credit facility and term loan facility, and the US private placement notes resulting in combined debt facilities of £1,831 million. The revolving credit and term loan facilities have an initial maturity date of April 20, 2026, and the Dowlais Group has the option to extend the maturity of the revolving credit facility by up to two years, at its sole discretion.

Revenue was £2,181 million for the six months ended June 30, 2025, a decrease of £108 million, or 4.7%, from £2,289 million in the six months ended June 30, 2024. Of this decrease, 2.5% was due to the impact of changes in translational foreign exchange rates compared to the prior year. In addition, the following impacted each of the segments:

· GKN Automotive: Revenue declined 3.9% year-on-year to £1,710 million, primarily driven by a 7.6% decrease in Driveline revenue. Driveline revenues declined 7.6%, of which 2.9% related to the impact of foreign exchange movements, compared to a 0.7% decline in light vehicle production volumes outside China, largely due to adverse customer mix and timing, as the phasing out of older programs was not fully compensated by new platform ramp-ups, which are expected to be more second-half weighted. Revenue from the ePowertrain product line grew 4.1% year-on-year, net of a 0.9% decline due to the impact of foreign exchange movements. This was largely due to a lower comparison base in H1 2024 and a recovery in volume on an AWD platform previously impacted by production delays.
· GKN Powder Metallurgy: Revenue declined 7.5% year-on-year to £471 million. The impact of changes in foreign exchange rates made up 3.0% of this decrease, with the remaining 4.4% decline largely driven by lower volumes in in Europe and North America, partially offset by volume growth in China. Revenue in the Sinter product line declined by 6.3%, of which foreign exchange rates accounted for a decrease of 3.3%, and the Powder product line was 15.8% lower compared to prior year mainly as result of customer/platform mix and a 2.3% reduction due to foreign exchange movements. The Acceleration Platforms product line performed strongly during the period with significant growth in metallic products resulting in growth of 2.9%, in particular due to revenue growth in thermal management products for AI infrastructure customers, which was offset by negative changes of 1.8% in foreign exchange rates.

Cost of sales

Cost of sales was £1,866 million for the six months ended June 30, 2025, a decrease of £77 million, or 4.0%, from £1,943 million in the six months ended June 30, 2024. Changes in foreign exchange rates made up 2.5% of the 4.0% decrease, with the remaining 1.5% reflecting the decline in sales volumes during the first six months of 2025.

Selling, general and administrative expenses (SG&A expenses)

SG&A expenses were £300 million for the six months ended June 30, 2025, a decrease of £132 million, or 30.6%, from £432 million in the six months ended June 30, 2024. The decrease in SG&A includes a £22 million decrease in R&D overhead costs following the Group's strategic decision to right size its engineering investment in the ePowertrain product line, and a decrease of £85 million in relation to the following items:

· Restructuring costs of £36 million were included in SG&A expenses for the six months ended June 30, 2025, a decrease of £13 million from £49 million in the six months ended June 30, 2024. This included £27 million of restructuring costs recorded in the GKN Automotive segment, compared with a charge of £43 million in the six months ended June 30, 2024, primarily relating to footprint consolidation actions as the business continues to address its cost base and deliver transformational programs. Costs incurred in the six months ended June 30, 2025 include direct costs relating to the closure of GKN Automotive plants in Köping, Sweden and Roxboro, North Carolina together with direct costs of expansion of the Group's production capacity in Mexico, and continued transfer of manufacturing from Mosel, Germany to Miskolc, Hungary. Restructuring costs also included a charge of £7 million recorded in the Powder Metallurgy segment relating to the optimization of headcount and reorganization of activities under the new commercial strategy, compared with a charge of £4 million in the six months ended June 30, 2024.

36

· Credits related to unrealized gains on derivatives and associated financial assets and liabilities of £49 million were recorded in SG&A expenses in the six months ended June 30, 2025, compared with charges related to losses of £35 million in the six months ended June 30, 2024. These are primarily forward foreign currency exchange contracts where hedge accounting is not applied and are entered into to mitigate the potential volatility of future cash flows, on long-term foreign currency customer and supplier contracts, including foreign exchange movements on the associated financial liabilities.
· SG&A expenses in the six months ended June 30, 2025 also included (i) a charge of £92 million related to amortization of intangible assets acquired in business combinations, compared to a charge of £96 million in the six months ended June 30, 2024; and (ii) costs of £16 million incurred in relation to the proposed combination with AAM.

Share of result of equity accounted investments, net of tax

The share of results of equity accounted investments, net of tax was £31 million for the six months ended June 30, 2025, an increase of £2 million, or 6.9%, from £29 million in the six months ended June 30, 2024. This increase was primarily due to stronger performance in the largest of the Dowlais Group's equity accounted investments, based in China.

Finance costs

Finance costs were £58 million for the six months ended June 30, 2025, a decrease of £11 million, or 14.7%, from £68 million in the six months ended June 30, 2024. The decrease primarily relates to fair value changes on other financial assets, which decreased from a charge of £9 million in the six months ended June 30, 2024 to a charge of £nil in 2025.

Finance income

Finance income was £6 million for the six months ended June 30, 2025, an increase of £4 million, or 200.0%, from £2 million in the six months ended June 30, 2024, reflecting increased bank interest receivable.

Tax

The Group's tax charge was £5 million for the six months ended June 30, 2025, compared with a tax credit of £25 million in the six months ended June 30, 2024, reflecting a £24 million reduction in deferred tax credit.

Revenue was £4,337 million in the financial year 2024, a decrease of £527 million, or 10.8%, from £4,864 million in the financial year 2023. Of this decrease, 3.4% was due to the impact of changes in translational foreign exchange rates compared to the prior year, with the British pound sterling strengthening against several currencies (at average exchange rates), particularly the US Dollar and the Euro. In addition, the following impacted each of the segments:

· GKN Automotive: Revenue declined 11.8% year-on-year to £3,391 million largely due to the impact of lower volumes and product mix in the ePowertrain product line, which continued to be impacted by volatility in BEV production volumes, driven by low double-digit decline in AWD systems, high single-digit decline in ePowertrain components and significant decline in eDrive systems. Driveline revenues declined 3.2% before considering the foreign exchange impact mentioned above, slightly outperforming a declining GLVP outside China of 3.3%, as it continued to demonstrate the resilience of its broad portfolio and scale across customers, platforms and geographies.
· GKN Powder Metallurgy: Revenue declined 6.9% year-on-year to £946 million. Of this decrease, 3.1% was due to customer/platform mix in the North American Sinter business, and 3.3% was due to the impact of changes in foreign exchange rates.

38

Cost of sales

Cost of sales was £3,691 million in the financial year 2024, a decrease of £416 million, or 10.1%, from £4,107 million in the financial year 2023. This decrease mostly reflected the decline in sales volumes during the financial year 2024.

Selling, general and administrative expenses (SG&A expenses)

SG&A expenses were £813 million in the financial year 2024, a decrease of £445 million, or 35.4%, from £1,258 million in the financial year 2023. This decrease was primarily due to the £449 million goodwill impairment charge recorded in the financial year 2023 relating to the Powder Metallurgy segment. The remaining £4 million increase in SG&A included a decrease of £69 million reflecting the impact of changes in foreign exchange rates and a reduction in spend in administrative expenses, offset by an increase of £73 million in relation to the following items:

· Restructuring costs of £145 million were included in SG&A expenses in the financial year 2024, an increase of £25 million from £120 million in the financial year 2023. This included £125 million of restructuring costs recorded in the GKN Automotive segment, compared with a charge of £109 million in the financial year 2023, primarily relating to significant footprint consolidation actions as the business continues to address its cost base and deliver transformational programs. Significant costs incurred in the year ended December 31, 2024 include direct costs relating to the closure of a GKN Automotive plant in Roxboro, North Carolina and direct costs of expansion in Mexico as new product lines are added to the facility, and continued transfer of manufacturing from Mosel, Germany to Miskolc, Hungary. Further costs have also been incurred reflecting the Dowlais Group's strategic decision to right size its engineering investment in the ePowertrain product line, with a primary focus on eDrive systems, to optimize capital allocation. Restructuring costs also included a charge of £17 million recorded in the Powder Metallurgy segment relating to the optimization of headcount and reorganization of activities under the new commercial strategy, compared with a charge of £10 million in the financial year 2023.
· Charges related to unrealized losses on derivatives and associated financial assets and liabilities of £71 million were recorded in SG&A expenses in the financial year 2024, compared with a credit related to gains of £16 million in the financial year 2023. These are primarily forward foreign currency exchange contracts where hedge accounting is not applied and are entered into to mitigate the potential volatility of future cash flows, on long-term foreign currency customer and supplier contracts, including foreign exchange movements on the associated financial liabilities.
· SG&A expenses in the financial year 2024 also included (i) a charge of £191 million related to amortization of intangible assets acquired in business combinations, compared to a charge of £197 million in the financial year 2023; (ii) a loss of £8 million relating to the disposal of the Hydrogen business on 29 July 2024 for nominal consideration (2023: £nil); (iii) a credit of £27 million recorded on the release of a warranty provision originally recognized as a fair value item on historical acquisitions. In the financial year 2023, a credit of £17 million was recognized relating to loss making contracts (previously recognized as a fair value item on historical acquisitions); and (iv) a charge of £1 million related to demerger costs (2023: £42 million).

Share of result of equity accounted investments, net of tax

The share of results of equity accounted investments, net of tax was £61 million in the financial year 2024, an increase of £10 million, or 19.6%, from £51 million in the financial year 2023. This increase was primarily due to consistent stronger performance in the largest of the Dowlais Group's equity accounted investments, based in China.

39

Finance costs

Finance costs were £131 million in the financial year 2024, an increase of £30 million, or 29.7%, from £101 million in the financial year 2023. The main driver of the increase was interest charges on bank loans and overdrafts, which were £26 million higher compared to the preceding year due to a full-year impact of the post demerger capital structure and draw-down on the revolving credit facility in the year.

Finance income

Finance income was £22 million in the financial year 2024, a decrease of £7 million, or 24.1%, from £29 million in the financial year 2023. In the prior year, finance income included the benefit of one-off foreign exchange gains of £22 million on loans with the Melrose Group up to the date of demerger. Offsetting this reduction was an £11 million release of accrued interest relating to a settlement agreement reached with German tax authorities in respect of prior years.

Tax

The tax credit was £47 million in the financial year 2024 compared to a tax credit of £27 million in the financial year 2023. The increased credit reflects the increase in loss before tax after adjusting for disallowable expenses, which included a £45 million credit related to a settlement agreement reached with German tax authorities in respect of the years 2010 to 2021.

Cash flows

Six months ended June 30, 2025 versus the six months ended June 30, 2024

The following table sets out financial information extracted from the cash flow statement for the six months ended June 30, 2025 and June 30, 2024:

For the six months

Net cash used in investing activities (51 ) (29 )
Net cash generated from/(used in) financing activities 5 (16 )
Net decrease in cash and cash equivalents, net of bank overdrafts (35 ) (10 )

Net cash from operating activities

Net cash from operating activities was £11 million for the six months ended June 30, 2025, compared to £35 million in the six months ended June 30, 2024. The reduction of £24 million primarily reflects adverse working capital movement of £3 million compared with the six months ended June 30, 2024, restructuring cash payments of £63 million being £12 million higher than the six months ended June 30, 2024, in support of ongoing performance improvement and footprint rationalization efforts, cash paid in 2025 relating to the AAM combination of £7 million, and an increase in tax paid of £5 million.

Net cash used in investing activities

Net cash used in investing activities was £51 million for the six months ended June 30, 2025, compared to £29 million in the six months ended June 30, 2024. The increase of £22 million primarily reflects lower dividends received from equity accounted investments of £45 million in 2025 compared with £70 million received in the six months ended June 30, 2024.

40

Net cash from/(used in) financing activities

Net cash from financing activities was £5 million for the six months ended June 30, 2025, compared to cash used in financing activities of £16 million in the six months ended June 30, 2024, with the difference reflecting increased net drawings on borrowing facilities of £62 million in 2025 compared with £44 million in the six months ended June 30, 2024.

Year ended December 31, 2024 versus year ended December 31, 2023

The following table sets out financial information extracted from the cash flow statements for the financial years 2024 and 2023.

For the year ended
December 31,
2024 2023
£ million
Net cash generated from operating activities 120 239
Net cash used in investing activities (119 ) (194 )
Net cash generated from/(used in) financing activities 17 23
Net increase/(decrease) in cash and cash equivalents, net of bank overdrafts 18 68

Net cash from operating activities

Net cash from operating activities was £120 million in the financial year 2024, compared to £239 million in the financial year 2023. The reduction of £119 million includes adverse working capital movement of £53 million, an increase in restructuring costs of £35 million and increased interest paid of £28 million. This was partially offset by demerger cash costs of £4 million, being £44 million lower than the preceding year (£48 million).

Net cash used in investing activities

Net cash used in investing activities was £119 million in the financial year 2024, compared to cash used in investing activities of £194 million in the financial year 2023. This was mainly due to lower capital expenditure of £191 million in the financial year 2024, a decrease of £104 million compared to £295 million in the financial year 2023, as it was adjusted to align with lower volumes and no material expenditure was incurred on new production facilities, primarily associated with footprint restructuring initiatives. This was partially offset by lower proceeds received from disposal of property, plant and equipment of £4 million, compared with £33 million in the financial year 2023.

Net cash from/(used in) financing activities

Net cash from financing activities was £17 million in the financial year 2024, compared to cash from financing activities of £23 million in the financial year 2023. The Dowlais Group implemented a share buy-back scheme in the financial year 2024, acquiring shares worth £26 million during the year. The Dowlais Group paid an interim and final dividend to equity shareholders in 2024, totaling £58 million. In the financial year 2023 the Dowlais Group paid an interim dividend of £19 million, but no final dividend as Dowlais Group plc did not exist at December 31, 2022. These reductions were offset by net drawings and repayments on borrowing facilities and cash settlements with related parties increasing to £129 million in the financial year 2024, compared with £93 million in the financial year 2023.

41

Liquidity and capital resources

Available cash and cash equivalents and debt facilities are reviewed regularly to ensure sufficient funds are available to support the Dowlais Group's activities.

The Dowlais Group's primary sources of liquidity are cash generated from operating activities and funds available under its multi-currency term loan, revolving credit facility and US private placement notes. At June 30, 2025, the Dowlais Group's cash and cash equivalents balance, net of overdrafts was £267 million (December 31, 2024: £323 million and December 31, 2023: £313 million), and a further £462 million (December 31, 2024: £534 million and December 31, 2023: £590 million) was available under the revolving credit facility, translating to a total liquidity position of £729 million (December 31, 2024: £857 million and December 31, 2023: £903 million).

As of June 30, 2025, the Dowlais Group's net indebtedness was £1,034 million, comprising:

(i) cash and cash equivalents of £325 million;
(ii) net of bank overdrafts of £58 million, current interest-bearing loans and borrowings of £185 million and non-current interest-bearing loans and borrowings of £1,116 million.

As of December 31, 2024, the Dowlais Group's net indebtedness was £968 million, comprising:

(i) cash and cash equivalents of £336 million;
(ii) net of bank overdrafts of £13 million and non-current interest-bearing loans and borrowings of £1,291 million.

In addition to the above, the Dowlais Group continues to be funded by its committed bank facility that includes a multi-currency denominated term loan of £100 million and €100 million as well as a multi-currency denominated revolving credit facility of £350 million, US$660 million and €450 million. The revolving credit and term loan facilities have an initial maturity date of April 20, 2026, however the Dowlais Group has the option to extend the maturity of the revolving credit facility by up to two years, at its sole discretion.

As of June 30, 2025, the Dowlais Group had 35% of its drawn debt at fixed interest rate. This is made up of the US private placement notes and interest rate swaps. The maturity dates of the interest rate swaps are aligned with those of the underlying debt facilities. The Dowlais Group's effective interest rate was 6.3%, in line with prior years.

As of December 31, 2024, the Dowlais Group had 46% of its drawn debt at fixed interest rates. The average interest rate payable on the Dowlais Credit Facilities and Dowlais Notes, net of the impact of interest rate hedging, was 6.3% for the year ended December 31, 2024.

Loans drawn under these facilities are guaranteed by Dowlais Group plc and certain of its subsidiaries. There is no security over any of the Dowlais Group's assets in respect of these facilities.

Working capital

The Dowlais Group has a small number of uncommitted working capital programs, which provide favorable financing terms on eligible customer receipts and competitive financing terms to suppliers on eligible supplier payments.

Businesses that participate in these customer-related finance programs have the ability to choose whether to receive payment earlier than the normal due date, for specific customers on a non- recourse basis.

Some suppliers may utilize the Dowlais Group's supplier finance programs, which are provided by a limited number of the Dowlais Group's relationship banks. There is no cost to the Dowlais Group for providing these programs to its suppliers. These arrangements do not change the date suppliers are due to be paid by Dowlais, and therefore there is no additional impact on the Dowlais Group's liquidity.

Critical accounting policies

The preparation of financial statements requires management to exercise judgment in applying the Dowlais Group's accounting policies. It also requires the use of certain critical accounting estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses. Actual results may differ from these estimates. The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimate is revised and in any affected future periods. There were no critical judgments made by management, however key sources of estimation uncertainty were identified in respect of key assumptions underpinning value in use calculations in goodwill impairment tests and assumptions applied in calculating the accounting values for retirement benefit obligations.

Further discussion of the critical accounting policies that are relevant to included in Note 2 to the financial information of the Dowlais Group in the section of this offering memorandum entitled "Index to Dowlais Consolidated Financial Statements."
