Effect of New Accounting Standards and Other Regulatory Pronouncements

Accounting Standards Update 2023-07

On November 27, 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standard Update (ASU) 2023-07 -Improvements to Reportable Segment Disclosures (Topic 280). ASU 2023-07 enhances existing annual segment requirements to include disclosure of significant segment expenses and other segment items by reportable segment that are regularly used by the Chief Operating Decision Maker (CODM) to evaluate segment performance. This guidance also requires annual disclosure of the title and position of the CODM. ASU 2023-07 also expands interim segment disclosure requirements to include all existing annual segment disclosures in addition to the new disclosure requirements for significant segment expenses and other segment items. This guidance became effective at the beginning of our 2024 fiscal year for annual requirements, and will become effective at the beginning of our 2025 fiscal year for interim requirements, using a retrospective transition method. We adopted this guidance retrospectively on January 1, 2024 for the annual requirements and will adopt the interim requirements on January 1, 2025. We are currently assessing the impact that this standard will have on our consolidated financial statements.

Accounting Standards Update 2023-09

On December 14, 2023, the FASB issued ASU 2023-09 -Improvements to Income Tax Disclosures (Topic 740). ASU 2023-09 expands the existing disclosure requirements for the annual rate reconciliation between the effective tax rate and the statutory federal tax rate by requiring reconciliation items to be disaggregated by defined categories and disclosed as both percentages and amounts. ASU 2023-09 also requires the disaggregation of income taxes paid by jurisdiction for each annual period presented. This guidance becomes effective at the beginning of our 2025 fiscal year, and may be applied either retrospectively or prospectively. We expect to adopt this guidance on January 1, 2025 and are currently assessing the impact that this standard will have on our consolidated financial statements.

Securities and Exchange Commission (SEC) Rule

In the first quarter of 2024, the SEC adopted "The Enhancement and Standardization of Climate-Related Disclosures for Investors," a rule that expands disclosure requirements, including climate-related risks and financial statement impacts, as well as disclosures related to greenhouse gas (GHG) emissions. The annual disclosures related to climate-related risks and financial statement impacts are required beginning with our 2025 fiscal year and the disclosures related to GHG emissions are required beginning with our 2026 fiscal year. The GHG emissions disclosures are also subject to limited assurance requirements by 2029 and reasonable assurance requirements by 2033. We are currently assessing the impact that this rule will have on our consolidated financial statements. In April 2024, the SEC issued an order staying the rule pending legal review of the petitions challenging the rule. This order does not amend the compliance dates required by the rule.

2. INVENTORIES

We state our inventories at the lower of cost or net realizable value. The cost of our inventories is determined using the first-in first-out method. When we determine that our gross inventories exceed usage requirements, or if inventories become obsolete or otherwise not saleable, we record a provision for such loss as a component of our inventory accounts.

Inventories consist of the following:

3. GOODWILL AND INTANGIBLE ASSETS

Goodwill The following table provides a reconciliation of changes in goodwill for the three months ended March 31, 2024:

We conduct our annual goodwill impairment test in the fourth quarter of each year, as well as whenever adverse events or changes in circumstances indicate a possible impairment. In performing this test, we utilize a third-party valuation specialist to assist management in determining the fair value of our reporting units. Fair value of each reporting unit is estimated based on a combination of discounted cash flows and the use of pricing multiples derived from an analysis of comparable public companies multiplied against historical and/or anticipated financial metrics of each reporting unit. These calculations contain uncertainties as they require management to make assumptions including, but not limited to, market comparables, future cash flows of the reporting units, and appropriate discount and long-term growth rates. This fair value determination is categorized as Level 3 within the fair value hierarchy.

At March 31, 2024, accumulated goodwill impairment losses were $1,435.5 million. All remaining goodwill is attributable to our Driveline reporting unit.

Other Intangible Assets The following table provides a reconciliation of the gross carrying amount and associated accumulated amortization for AAM's other intangible assets, which are all subject to amortization:

Amortization expense for our intangible assets was $20.7 million for the three months ended March 31, 2024 and $21.4 million for the three months ended March 31, 2023. Estimated amortization expense for the years 2024 through 2028 is expected to be in the range of approximately $80 million to $85 million per year.

4. LONG-TERM DEBT

Long-term debt consists of the following:

Senior Secured Credit Facilities Our Senior Secured Credit Facilities are comprised of the Revolving Credit Facility, Term Loan A Facility and Term Loan B Facility. The Revolving Credit Facility and Term Loan A Facility mature in the first quarter of 2027 and the Term Loan B Facility matures in the fourth quarter of 2029. At March 31, 2024, we had $892.3 million available under the Revolving Credit Facility. This availability reflects a reduction of $32.7 million primarily for standby letters of credit issued against the facility. In the first quarter of 2023, we paid $25.0 million on our Revolving Credit Facility that had been drawn in the fourth quarter of 2022.

As of March 31, 2024, we have prepaid $19.5 million of the outstanding principal on our Term Loan A Facility and $18.6 million of the outstanding principal on our Term Loan B Facility. These payments satisfy our obligation for principal payments under the Term Loan A Facility through the end of 2024 and under the Term Loan B Facility through the end of 2026.

The Senior Secured Credit Facilities provide back-up liquidity for our foreign credit facilities. We intend to use the availability of long-term financing under the Senior Secured Credit Facilities to refinance any current maturities related to such debt agreements that are not otherwise refinanced on a long-term basis in their local markets, except where otherwise reclassified to Current portion of long-term debt on our Condensed Consolidated Balance Sheet.

Redemption of 6.25% Notes Due 2026 In the first quarter of 2024, we completed an open market repurchase of our 6.25% Notes due 2026 of $1.7 million.

Repayment of Tekfor Group Indebtedness In the first quarter of 2024, we repaid $6.6 million of outstanding indebtedness that we assumed upon our acquisition of Tekfor in June 2022.

Foreign credit facilities and Other We utilize local currency credit facilities to finance the operations of certain foreign subsidiaries. At March 31, 2024, $42.4 million was outstanding under our foreign credit facilities, as compared to $51.8 million at December 31, 2023. At March 31, 2024, an additional $83.4 million was available under our foreign credit facilities.

Weighted-Average Interest Rate The weighted-average interest rate of our long-term debt outstanding was 7.1% at both March 31, 2024 and December 31, 2023.

5. DERIVATIVES

Our business and financial results are affected by fluctuations in global financial markets, including currency exchange rates and interest rates. Our hedging policy has been developed to manage these risks to an acceptable level based on management’s judgment of the appropriate trade-off between risk, opportunity and cost. We do not hold financial instruments for trading or speculative purposes.

Currency derivative contracts From time to time, we use foreign currency forward contracts to reduce the effects of fluctuations in exchange rates relating to certain foreign currencies. As of March 31, 2024 and December 31, 2023, we had currency forward contracts outstanding with a total notional amount of $227.3 million and $206.9 million, respectively, that hedge our exposure to changes in foreign currency exchange rates for certain payroll expenses into the fourth quarter of 2026 and the purchase of certain direct and indirect inventory and other working capital items into the fourth quarter of 2024.

Fixed-to-fixed cross-currency swap In 2022, we entered into a fixed-to-fixed cross-currency swap to reduce the variability of functional currency equivalent cash flows associated with changes in exchange rates on certain Euro-based intercompany loans. We had notional amounts outstanding under fixed-to-fixed cross-currency swaps of €200.0 million at both March 31, 2024 and December 31, 2023, which were equivalent to $215.8 million and $220.7 million, respectively. The fixed-to-fixed cross-currency swap hedges our exposure to changes in exchange rates on the intercompany loans through the second quarter of 2024.

Variable-to-fixed interest rate swaps In 2023, we entered into variable-to-fixed interest rate swaps to reduce the variability of cash flows associated with interest payments on our variable rate debt. As of March 31, 2024, we have $700.0 million notional amount hedged in relation to our variable-to-fixed interest rate swaps into the third quarter of 2027, $200.0 million of which continues into the fourth quarter of 2029.

The following table summarizes the reclassification of pre-tax derivative gains and losses into net income (loss) from accumulated other comprehensive income (loss) for those derivative instruments designated as cash flow hedges under Accounting Standards Codification (ASC) 815 -Derivatives and Hedging:

See Note 7 - Reclassifications out of Accumulated Other Comprehensive Income (Loss) (AOCI) for amounts recognized in other comprehensive income during the three months ended March 31, 2024 and 2023.

The following table summarizes the amount and location of gains and losses recognized in the Condensed Consolidated Statements of Operations for those derivative instruments not designated as hedging instruments under ASC 815:

6. FAIR VALUE

ASC 820 -Fair Value Measurement defines fair value as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” The definition is based on an exit price rather than an entry price, regardless of whether the entity plans to hold or sell the asset. This guidance also establishes a fair value hierarchy to prioritize inputs used in measuring fair value as follows:

•Level 1: Observable inputs such as quoted prices in active markets;

•Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and

•Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop

its own assumptions.

Financial instruments The estimated carrying value of our financial assets and liabilities that are recognized at fair value on a recurring basis, using available market information and other observable data, are as follows:

The carrying values of our cash, accounts receivable, accounts payable and accrued liabilities approximate their fair values due to the short-term maturities of these instruments. The carrying values of our borrowings under the foreign credit facilities approximate their fair value due to the frequent resetting of the interest rates.

We have an investment in the equity securities of REE Automotive, which are measured at fair value each reporting period with changes in fair value reported through an unrealized holding gain or loss within Other income (expense), net in our Condensed Consolidated Statement of Operations. As of March 31, 2024, our investment in REE shares was valued at $0.9 million based on a closing price on that date of $5.84 per share.

We estimated the fair value of the amounts outstanding on our debt using available market information and other observable data, to be as follows:

7. RECLASSIFICATIONS OUT OF ACCUMULATED OTHER COMPREHENSIVE INCOME (LOSS) (AOCI)

Reclassification adjustments and other activity impacting accumulated other comprehensive income (loss) during the three months ended March 31, 2024 and March 31, 2023 are as follows(in millions):

8. EMPLOYEE BENEFIT PLANS

The components of net periodic benefit cost (credit) are as follows:

The noncurrent liabilities associated with our pension and other postretirement benefit plans are classified as Postretirement benefits and other long-term liabilities on our Condensed Consolidated Balance Sheets. As of March 31, 2024 and December 31, 2023, we have a noncurrent pension liability of $72.7 million and $74.7 million, respectively. As of March 31, 2024 and December 31, 2023, we have a noncurrent other postretirement benefits liability of $268.4 million and $268.9 million, respectively.

Due to the availability of our pre-funded pension balances (previous contributions in excess of prior required pension contributions), we expect our regulatory pension funding requirements in 2024 to be less than $1.0 million. We expect our cash payments for other postretirement benefit obligations in 2024, net of GM cost sharing, to be approximately $11.0 million.

9. PRODUCT WARRANTIES

We record a liability for estimated warranty obligations at the dates our products are sold. These estimates are established using sales volumes and internal and external warranty data where there is no payment history and historical information about the average cost of warranty claims for customers with prior claims. We estimate our costs based on the contractual arrangements with our customers, existing customer warranty terms and internal and external warranty data, which includes a determination of our warranty claims and actions taken to improve product quality and minimize warranty claims. We continuously evaluate these estimates and our customers' administration of their warranty programs. We monitor actual warranty claim data and adjust the liability, as necessary, on a quarterly basis.

The following table provides a reconciliation of changes in the product warranty liability:

10. REVENUE FROM CONTRACTS WITH CUSTOMERS

Net sales recognized from contracts with customers, disaggregated by segment and geographical location, are presented in the following table for the three months ended March 31, 2024 and 2023. Net sales are attributed to regions based on the location of production. Intersegment sales have been excluded from the table.

Contract Assets and Liabilities

The following table summarizes our beginning and ending balances for accounts receivable and contract liabilities associated with our contracts with customers(in millions):

Contract liabilities relate to deferred revenue associated with various settlements and commercial agreements for which we have a future performance obligation to the customer. We recognize this deferred revenue into revenue over the life of the associated program as we satisfy our performance obligations to the customer. We do not have contract assets as defined in ASC 606. We amortized previously recorded contract liabilities into revenue as we satisfied performance obligations with our customers of approximately $4.0 million and $7.6 million for the three months ended March 31, 2024 and 2023, respectively.

11. RESTRUCTURING AND ACQUISITION-RELATED COSTS

In 2022, we completed our acquisition of Tekfor Group (Tekfor) and in 2023 initiated certain restructuring actions associated with the acquired entities. We expect to incur restructuring costs associated with the acquired entities throughout 2024.

In the first quarter of 2024, we initiated a global restructuring program (the 2024 Program) focused on optimizing our cost structure. We expect to incur costs under the 2024 Program into 2026.

A summary of our restructuring activity for the first three months of 2024 and 2023 is shown below:

As part of our restructuring actions, we incurred total severance charges of approximately $0.2 million and $0.3 million during the three months ended March 31, 2024 and 2023, respectively. We also incurred total implementation costs of approximately $1.2 million and $3.7 million during the three months ended March 31, 2024 and 2023, respectively. Implementation costs consist primarily of plant exit costs. We incurred $0.2 million of costs related to restructuring actions associated with Tekfor and $1.2 million of costs under the 2024 Program in the three months ended March 31, 2024. We have incurred $2.3 million of total restructuring costs related to restructuring actions associated with Tekfor. Approximately $1.1 million of our total restructuring costs for the three months ended March 31, 2024 related to our Metal Forming segment, while the remainder were corporate costs. Substantially all of our total restructuring costs for the three months ended March 31, 2023 related to our Metal Forming segment. We expect to incur approximately $10 million to $20 million of total restructuring charges in 2024 associated with Tekfor and the 2024 Program.

The following table represents a summary of integration charges incurred primarily related to our acquisition of Tekfor:

Integration expenses primarily reflect costs incurred for information technology infrastructure and enterprise resource planning systems, and consulting fees incurred in conjunction with integration activities. Total restructuring charges and acquisition-related charges are presented on a separate line item titled Restructuring and acquisition-related costs in our Condensed Consolidated Statements of Operations and totaled $2.5 million and $4.8 million for the three months ended March 31, 2024 and March 31, 2023, respectively.

12. INCOME TAXES

We adjust our effective tax rate each quarter based on our estimated annual effective tax rate. We also record the tax impact of certain discrete, unusual or infrequently occurring items, including changes in judgment about valuation allowances and the effects of changes in tax laws or rates on deferred tax balances, in the interim period in which they occur. In addition, jurisdictions with a projected loss for the year or a year-to-date loss where no tax benefit can be recognized are excluded from the estimated annual effective tax rate. The impact of such an exclusion could result in a higher or lower effective tax rate during a particular quarter, based upon the mix and timing of actual earnings versus annual projections.

Our income tax expense and effective income tax rate for the three months ended March 31, 2024 and 2023 are as follows:

During the three months ended March 31, 2024 and 2023, in computing our estimated annual effective tax rate, we recorded a full valuation allowance against the deferred tax asset on the current year estimated disallowed interest expense in the U.S. In addition, during the three months ended March 31, 2023, we recorded a valuation allowance against a portion of the deferred tax asset on prior year disallowed interest expense in the U.S. and reduced our liability for unrecognized income tax benefits and related interest and penalties as a result of a change in estimate on previously recorded unrecognized tax benefits in certain jurisdictions, resulting in net tax expense of $3.4 million during the three months ended March 31, 2023.

Our effective income tax rate for the three months ended March 31, 2024 varies from our effective income tax rate for the three months ended March 31, 2023 primarily as a result of the mix of earnings on a jurisdictional basis and the impact of the discrete items noted above.

For the three months ended March 31, 2024, our effective income tax rate varies from the U.S. federal statutory rate primarily due to the unfavorable impact related to the disallowed interest expense deductions in the U.S. and tax expense related to global intangible low-taxed income (GILTI), net of the favorable impact of certain foreign tax rates and the impact of tax credits. For the three months ended March 31, 2023, our effective income tax rate varies from the U.S. federal statutory rate primarily due to the unfavorable impact related to the disallowed interest expense deductions in the U.S. and tax expense related to GILTI, net of the impact of the reduction in unrecognized tax benefits, favorable foreign tax rates and the impact of tax credits.

In accordance with the guidance in ASC 740 -Income Taxes, we review the likelihood that we will realize the benefit of deferred tax assets and estimate whether recoverability of our deferred tax assets is "more likely than not" based on the available evidence. If we experience lower than projected earnings in certain jurisdictions in future periods, it is reasonably possible that changes in valuation allowances could be recognized and such changes could be material to our financial statements.

Other Income Tax Matters

During their examination of our 2015 U.S. federal income tax return, the Internal Revenue Service (IRS) asserted that income earned by a Luxembourg subsidiary from its Mexican branch operations should be categorized as foreign base company sales income (FBCSI) under Section 954(d) of the Internal Revenue Code and recognized currently as taxable income on our 2015 U.S. federal income tax return. As a result of this assertion, the IRS issued a Notice of Proposed Adjustment (NOPA). AAM disagreed with the NOPA, believes that the proposed adjustment is without merit and contested the matter through the IRS's administrative appeals process. No resolution was reached in the appeals process and, in September 2022, the IRS issued a Notice of Deficiency. The IRS subsequently issued a Notice of Tax Due in December 2022 and AAM paid the assessed tax and interest of $10.1 million in January 2023. We filed a claim for refund for the amount of tax and interest paid related to this matter for the 2015 tax year and, in December 2023, we filed suit in the U.S. Court of Federal Claims.

We believe, after consultation with tax and legal counsel, that it is more likely than not that our structure did not give rise to FBCSI, and it's likely that we will be successful in ultimately defending our position. As such, we have not recorded any impact of the IRS’s proposed adjustment in our condensed consolidated financial statements as of, and for the three months ended, March 31, 2024 and March 31, 2023, with the exception of the cash payment and associated income tax receivable of $10.1 million paid by AAM to the IRS in 2023. As of March 31, 2024, in the event AAM is not successful in defending its position, the potential additional income tax expense, including estimated interest charges, related to tax years 2015 through 2023, is estimated to be in the range of approximately $300 million to $350 million.

Negative or unexpected outcomes of tax examinations and audits, and any related litigation, could have a material adverse impact on our results of operations, financial condition and cash flows. We will continue to monitor the progress and conclusions of all ongoing audits and other communications with tax authorities and will adjust our estimated liability as necessary. As of March 31, 2024 and December 31, 2023, we have recorded a liability for unrecognized income tax benefits and related interest and penalties of $30.4 million and $38.1 million, respectively.

13. EARNINGS (LOSS) PER SHARE (EPS)

We present EPS using the two-class method. This method allocates undistributed earnings between common shares and non-vested share-based payment awards that entitle the holder to non-forfeitable dividend rights. Our participating securities are our non-vested restricted stock units.

The following table sets forth the computation of our basic and diluted EPS available to shareholders of common stock (excluding participating securities):

Basic and dilutive loss per share are the same for the three months ended March 31, 2023 because the effect of potentially dilutive stock-based compensation would have been antidilutive. Excluded potentially dilutive shares were 0.2 million for the three months ended March 31, 2023.

14. SEGMENT REPORTING

Our business is organized into Driveline and Metal Forming segments, with each representing a reportable segment under ASC 280 -Segment Reporting. The results of each segment are regularly reviewed by the chief operating decision maker to assess the performance of the segment and make decisions regarding the allocation of resources to the segments.

Our product offerings by segment are as follows:

•Driveline products consist primarily of front and rear axles, driveshafts, differential assemblies, clutch modules, balance shaft systems, disconnecting driveline technology, and electric and hybrid driveline products and systems for light trucks, sport utility vehicles (SUVs), crossover vehicles, passenger cars and commercial vehicles; and

•Metal Forming products consist primarily of engine, transmission, driveline and safety-critical components for traditional internal combustion engine and electric vehicle architectures including light vehicles, commercial vehicles and off-highway vehicles, as well as products for industrial markets.

We 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 define EBITDA to be earnings before interest expense, income taxes, depreciation and amortization. Segment Adjusted EBITDA is defined as EBITDA for our reportable segments excluding the impact of restructuring and acquisition-related costs, debt refinancing and redemption costs, unrealized gains or losses on equity securities, pension curtailment and settlement charges and non-recurring items.

The following tables represent information by reportable segment for the three months ended March 31, 2024 and 2023(in millions):

The following table represents a reconciliation of Total Segment Adjusted EBITDA to consolidated income (loss) before income taxes for the three months ended March 31, 2024 and 2023:
