Revenue Recognition and Contracts with Customers

12 Months Ended

Dec. 31, 2025

Revenue from Contract with Customer [Abstract]

Revenue Recognition and Contracts with Customers

Note 3. Revenue Recognition and Contracts with Customers

The Company generates revenue through the sale of products to customers in the OEM and aftermarket channels. OEM and aftermarket contracts generally include scheduling agreements that stipulate the pricing and delivery terms that identify the quantity and timing of the product to be transferred.

Disaggregated Revenue

For Net sales by region (determined based on country of shipment) and channel, refer to Note 25, Segments and Concentrations. We recognize virtually all of our revenues arising from performance obligations at a point in time. Less than 1% of our revenue is satisfied over time.

Contract Balances

The timing of revenue recognition, billings and cash collections results in unbilled receivables (contract assets) and billed accounts receivable, reported in Accounts, notes and other receivables – net, and customer advances and deposits (contract liabilities), reported in Accrued Liabilities, on the Consolidated Balance Sheets. Contract assets arise when the timing of billing to customers differs from the timing of revenue recognition. Contract assets are recognized when the revenue associated with the contract is recognized prior to billing and derecognized once invoiced in accordance with the terms of the contract. Contract liabilities are recorded in scenarios where we enter into arrangements where customers are

contractually obligated to remit cash payments in advance of us satisfying performance obligations and recognizing revenue. Contract liabilities are generally derecognized when revenue is recognized.

These assets and liabilities are reported on the Consolidated Balance Sheets on a contract-by-contract basis at the end of each reporting period.

The following table summarizes our contract assets and liabilities balances:


	2025		2024
	(Dollars in millions)
Contract assets—January 1	$	40	$	38
Contract assets—December 31	48		40
Change in contract assets—Increase/(Decrease)	$	8	$	2
Contract liabilities—January 1	$	(8)	$	(11)
Contract liabilities—December 31	(10)		(8)
Change in contract liabilities—(Increase)/Decrease	$	(2)	$	3

Performance Obligations

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, the performance obligation is satisfied. For product sales, typically each product sold to a customer represents a distinct performance obligation.

Performance obligations are supported by contracts with customers, providing a framework for the nature of the distinct goods, services or bundle of goods and services. The timing of satisfying the performance obligation is typically indicated by the terms of the contract. All performance obligations are expected to be satisfied within one year, with substantially all performance obligations being satisfied within a month.

The timing of satisfaction of our performance obligations does not significantly vary from the typical timing of payment, with most cash advances (contract liabilities) and unbilled receivables (contract assets) being settled within 3 months. For some contracts, we may be entitled to receive an advance payment.

We have applied the practical expedient to not disclose the value of remaining performance obligations for contracts with an original expected term of one year or less.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Summary of Significant Accounting Policies (Policies)	12 Months Ended
Summary of Significant Accounting Policies (Policies)	Dec. 31, 2025
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Consolidated Financial Statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). All amounts presented are in millions, except per share amounts. We evaluate segment reporting in accordance with ASC 280, Segment Reporting. We concluded that Garrett operates in a single operating segment and a single reportable segment based on the operating results available and evaluated regularly by the chief operating decision maker (“CODM”), who is our Chief Executive Officer, to make decisions about resource allocation and performance assessment. The CODM makes operational performance assessments and resource allocation decisions on a consolidated basis, inclusive of all of the Company’s products across channels and geographies.
Use of Estimates	Use of Estimates The preparation of the Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates and assumptions are periodically reviewed and the effects of changes are reflected in the Consolidated Financial Statements in the period they are determined to be necessary.
Principles of Consolidation and Combination	Principles of Consolidation and Combination The Consolidated Financial Statements include the accounts of Garrett Motion Inc. and all of its subsidiaries in which a controlling financial interest is maintained. We consolidate entities that we control due to ownership of a majority voting interest, and we consolidate variable interest entities when we have variable interests and are the primary beneficiary. Our consolidation policy requires equity investments that we exercise significant influence over but in which we do not have a controlling financial interest to be accounted for using the equity method. Investments through which we are not able to exercise significant influence over the investee and which we do not have readily determinable fair values are accounted for under the cost method. All intercompany transactions and balances are eliminated in consolidation.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents include cash on hand and highly liquid investments having an original maturity of three months or less.
Restricted Cash	Restricted Cash Restricted cash primarily consists of bank deposits pledged as collateral to issue bank notes
Trade Receivables and Allowance for Doubtful Accounts	Trade Receivables and Allowance for Doubtful Accounts Trade accounts receivable are recorded at the invoiced amount as a result of transactions with customers. In accordance with ASC 326, Financial Instruments - Credit Losses, the Company maintains allowances for doubtful accounts for losses as a result of a customer’s inability to make required payments, estimated based on the expected credit losses over the contractual life of the receivables based on days past due as measured from the contractual due date and collection history. The Company also takes into consideration changes in economic conditions that may not be reflected in historical trends (for example, customers in bankruptcy, liquidation or reorganization). Receivables are written-off against the allowance for doubtful accounts when they are determined uncollectible. Such determination includes analysis and consideration of the particular conditions of the account, including time intervals since last collection, customer performance against agreed upon payment plans, solvency of customer and any bankruptcy proceedings.
Transfer of Financial Instruments	Transfer of Financial Instruments Sales and transfers of financial instruments are accounted for under ASC 860, Transfers and Servicing. The Company may discount and sell accounts receivables during the normal course of business. These receivables which are transferred to a third party without recourse to the Company and that meet the criteria of sales accounting as per ASC 860, are excluded from the amounts reported in the Consolidated Balance Sheets. The cash proceeds received from such sales are included in operating cash flows. The expenses associated with the factoring of receivables are recorded within Other expense, net in the Consolidated Statements of Operations. The Company may also receive bank notes in settlement of accounts receivables, primarily in the Asia Pacific region. Such bank notes are classified as notes receivables under Accounts, notes and other receivables – net in the Consolidated Balance Sheets. The collections of such bank notes are included in operating cash flows and any expenses related to discounting these are included within Other expense, net in the Consolidated Statements of Operations. The Company can hold the bank notes until maturity, exchange them with suppliers to settle liabilities, or sell them to third party financial institutions in exchange for cash.
Inventories	Inventories Inventories are stated at the lower of cost, determined on a first-in, first-out basis, including direct material costs and direct and indirect manufacturing costs, or net realizable value. Obsolete inventory is identified based on analysis of inventory for known obsolescence issues. The original equipment inventory on hand in excess of forecasted usage and lack of consumption in the previous 12 months is fully reserved, unless the value of such material is recoverable from either the vendor or the customer.
Property, Plant and Equipment, Net	Property, Plant and Equipment, Net Property, plant and equipment are recorded at cost less accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of assets, which are 10 to 50 years for buildings and improvements, 2 to 16 years for machinery and equipment, 3 to 10 years for tooling equipment, and 5 to 7 years for software. Maintenance and repairs are expensed as incurred. Impairment testing of long lived assets is completed by the Company in accordance with ASC 360, Property, Plant and Equipment. The testing is completed when a triggering event occurs, or at least on an annual basis to assess if any impairment triggering events existed during the year. If a triggering event occurs or is identified, the impairment testing is completed using the two-step impairment model. Asset classes are identified and tested for recoverability by comparing the net carrying value of the asset group to the undiscounted net cash flows to be generated from the use and eventual disposition of that asset group. If the carrying amount of an asset group is not recoverable, an impairment loss is recognized if the carrying amount exceeds the fair value. The impairment analysis was completed in 2025 with no triggering events identified.
Leases	Leases Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date of a lease (the “commencement date”) based on the present value of lease payments over the lease term. We determine if an arrangement is a lease at inception. Operating leases are included in Other assets, Accrued liabilities, and Other liabilities in our Consolidated Balance Sheets. Finance leases are included in Property, plant and equipment - net in our Consolidated Balance Sheets. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease where it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Variable lease payments are expensed in the period in which they occur. We have lease agreements with lease and non-lease components, which are generally accounted for separately. For machinery and equipment, we account for the lease and non-lease components as a single lease component. We account for short-term leases by recognizing lease payments in net income on a straight-line basis over the lease term and will not recognize any ROU assets and lease liabilities on the Consolidated Balance Sheet.
Goodwill	Goodwill Goodwill is subject to impairment testing annually, and whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. This testing compares carrying value to fair value of our single reporting unit. The Company recognizes an impairment charge for the amount by which the carrying value of the reporting unit exceeds the reporting unit´s fair value. However, any impairment should not exceed the amount of goodwill allocated to the reporting unit. Because we have a single reporting unit with a negative carrying value, no impairment was recognized.
Warranties and Guarantees	Warranties and Guarantees Expected warranty costs for products sold are recognized based on an estimate of the amount that eventually will be required to settle such obligations. These accruals are based on factors such as past experience, length of the warranty and various other considerations. Costs of product recalls, which may include the cost of the product being replaced as well as the customer’s cost of the recall, including labor to remove and replace the recalled part, are accrued as part of our warranty accrual at the time an obligation becomes probable and can be reasonably estimated. These estimates are adjusted from time to time based on facts and circumstances that impact the status of existing claims.
Sales Recognition	Sales Recognition Product sales are recognized when we transfer control of the promised goods to our customer, which is based on shipping terms. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring the promised goods, adjusted for any variable consideration such as price concessions or annual price adjustments as estimated at contract inception. Amounts billed but ultimately expected to be refunded to the customer are recorded as part of the customer pricing reserve within Accrued liabilities on the Consolidated Balance Sheet. In the sale of products in the OEM channel, the transaction price for these goods is generally equal to the agreed price of each unit and represents the standalone selling price for the unit. In the sale of products in the aftermarket channel, the terms of a contract or the historical business practice can give rise to variable consideration due to, but not limited to, discounts and rebates. We estimate variable consideration at the most likely amount we will receive from customers and reduce revenues recognized accordingly. We include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. We adjust our estimate of revenue at the earlier of when the value of consideration we expect to receive changes or when the consideration becomes fixed.
Research, Development and Engineering	Research, Development and Engineering Garrett conducts research, development and engineering (“RD&E”) activities which consist primarily of the development of new products and product applications. RD&E costs are included in Cost of goods sold. Customer reimbursements are netted against gross RD&E expenses as they are considered a recovery of cost. RD&E costs are charged to expense as incurred unless the Company has a contractual guarantee of reimbursement from the customer, in which case the related costs are capitalized. Total RD&E expenses, net of customer reimbursements, amounted to $151 million, $161 million and $163 million for the years ended December 31, 2025, 2024 and 2023, respectively. As of December 31, 2025 and 2024, $52 million and $29 million, respectively, of contractually reimbursable costs were capitalized. These amounts are recorded within Other current assets and Other assets in the Consolidated Balance Sheets.
Government Incentives	Government Incentives The Company receives incentives from governmental entities related to expenses, assets, and other activities. The associated terms of the incentives can vary by country. Government incentives are recorded in the financial statements in accordance with their purpose as a reduction of expense, a reduction of asset cost or other operating or non-operating income. Incentives are recognized when there is probable assurance that the Company will comply with the conditions for the incentives and a reasonable expectation that the funds will be received. Government incentives received prior to being earned are recognized as deferred income whereas incentives earned prior to being received are recognized as receivables. The Company recognized government incentives of $18 million, $19 million and $14 million for the years ended December 31, 2025, 2024 and 2023, respectively. These amounts are recorded in Cost of goods sold and Selling, general and administrative expenses in the Consolidated Statements of Operations.
Supplier Financing	Supplier Financing The Company has supplier financing arrangements with two third-party financial institutions under which certain suppliers may factor their receivables from Garrett. The Company also enters into arrangements with banking institutions to issue bankers acceptance drafts in settlement of accounts payables, primarily in the Asia Pacific region. The bankers acceptance drafts, or guaranteed bank notes, have a contractual maturity of six months or less, and may be held by suppliers until maturity, transferred to their suppliers, or discounted with financial institutions in exchange for cash. Supplier financing obligations outstanding and guaranteed bank notes outstanding are recorded within Accounts payable.
Environmental Matters	Environmental Matters The Company records liabilities for environmental assessments and remediation activities in the period in which it is probable that a liability has been incurred and the amount of that liability can be reasonably estimated. Estimated costs are recorded at undiscounted amounts, based on experience and assessments and are regularly evaluated. To the extent that the required remediation procedures change, or additional contamination is identified, the Company’s estimated environmental liabilities may also change. The liabilities are recorded in Accrued liabilities and Other liabilities in the Consolidated Balance Sheets.
Stock-Based Compensation	Stock-Based Compensation The principal awards issued under our stock-based compensation plans, which are described in Note 21, Stock-Based Compensation, are performance stock units and restricted stock units. The cost for such awards is measured at the grant date based on the fair value of the award. Compensation expense is recognized over the requisite service periods (generally the vesting period of the equity award) based on the Company's best estimate of ultimate performance against the award targets, and is included in Selling, general and administrative expenses in the Consolidated Statements of Operations. The Company accounts for forfeitures as they occur.
Pension Benefits	Pension Benefits We sponsor defined benefit pension plans covering certain employees, primarily in Switzerland, the U.S. and Ireland. For such plans, we are required to disaggregate the service cost component of net benefit costs and report those costs in the same line item or items in the Consolidated Statements of Operations as other compensation costs arising from services rendered by the pertinent employees during the period. The other non-service components of net benefit costs are required to be presented separately from the service cost component. We record the service cost component of Pension expense (income) in Cost of goods sold or Selling, general and administrative expenses. The remaining components of net benefit costs within Pension expense (income), primarily interest costs and assumed return on plan assets, are recorded in Non-operating expense (income). We recognize net actuarial gains or losses in excess of 10% of the greater of the fair value of plan assets or the plans’ projected benefit obligation (the corridor) annually in the fourth quarter each year (the “MTM Adjustment”). The MTM Adjustment is recorded in Non-operating expense (income).
Foreign Currency Translation	Foreign Currency Translation Assets and liabilities of subsidiaries operating outside the United States with a functional currency other than U.S. Dollars are translated into U.S. Dollars using year-end exchange rates. Sales, costs and expenses are translated at the average exchange rates in effect during the year. Foreign currency translation gains and losses are included as a component of Accumulated other comprehensive income ("AOCI").
Derivative Financial Instruments	Derivative Financial Instruments We minimize our risks from foreign currency exchange rate fluctuations through our normal operating and financing activities and, when deemed appropriate, through the use of derivative financial instruments. Derivative financial instruments are used to manage risk and are not used for trading or other speculative purposes. Derivative financial instruments that qualify for hedge accounting must be designated and effective as a hedge of the identified risk exposure at the inception of the contract. Accordingly, changes in fair value of the derivative contract must be highly correlated with changes in fair value of the underlying hedged item at inception of the hedge and over the life of the hedge contract. All derivatives are recorded on the Consolidated Balance Sheets as assets or liabilities and measured at fair value. For derivatives designated as cash flow hedges, the effective portion of the changes in fair value of the derivatives are recorded in AOCI and subsequently recognized in earnings when the hedged items impact earnings. Cash flows of such derivative financial instruments are classified consistent with the underlying hedged items. For derivatives designated as net investment hedges, provided the hedging relationship is highly effective, the changes in fair value of the derivatives are recorded in AOCI until the net investment is liquidated or sold.
Income Taxes	Income Taxes We account for income taxes pursuant to the asset and liability method which requires us to recognize current tax liabilities or receivables for the amount of taxes we estimate are payable or refundable for the current year and deferred tax assets and liabilities for the expected future tax consequences attributable to temporary differences between the financial statement carrying amounts and their respective tax bases of assets and liabilities and the expected benefits of net operating loss and credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period enacted. A valuation allowance is provided when it is more likely than not that a portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income and the reversal of deferred tax liabilities during the period in which related temporary differences become deductible. We reclassify taxes from AOCI to earnings as the items to which the tax effects relate are similarly reclassified.
Earnings per share	Earnings per share Basic earnings per share for the years ended December 31, 2025, 2024 and 2023 are calculated using the two-class method. In 2025 and 2024, the deferred stock units related to the stock-based compensation plan contain non-forfeitable rights to dividends and are considered as participating securities, while in 2023 our Series A Preferred Stock was considered a participating security prior to its conversion into Common Stock and cancellation pursuant to the Transaction. The two-class method requires an allocation of earnings to all securities that participate in dividends with common shares to the extent that each such security may share in the Company's earnings. Basic earnings per share are calculated by dividing undistributed earnings allocated to Common Stock by the weighted average number of common shares. Diluted earnings per share for the years ended December 31, 2025 and 2024 are calculated by applying the two-class method for participating securities and then incorporating the dilutive effects of other potential common shares, determined using methods such as the treasury stock method, to arrive at the most dilutive EPS. Diluted earnings per share for the year ended December 31, 2023 are calculated by evaluating the more dilutive impact of both the two-class method and the if-converted method. The two-class method uses net income available to common shareholders and assumes conversion of all potential shares other than the participating securities. The if-converted method uses net income and assumes conversion of all potential shares including the participating securities.
Related Party Transactions	Related Party Transactions We contract with Trane Technologies ("Trane") for the occasional purchase of goods and services. Mr. Paul Camuti, a director on our Board of Directors, served as an executive officer of Trane through December 31, 2024, and was considered a related party until that time. Our payments under the agreements with Trane amounted to $1 million for the year ended December 31, 2024, and were included in Cost of goods sold in our Consolidated Statement of Operations. The liability balance due to Trane as of December 31, 2024, was immaterial. We lease certain facilities and receive property maintenance services from Honeywell International ("Honeywell") which, as of April 30, 2021 was the owner of our Series B Preferred Stock that has since been fully redeemed by the Company, is a holder of our Common Stock and was also a holder of our Series A Preferred Stock prior to the Transaction, as discussed below and in Note 19, Equity. We also contract with Honeywell for the occasional purchase of certain goods and services. Lease and service agreements were made at commercial terms prevalent in the market at the time they were executed. Honeywell is not considered a related party subsequent to the Transaction, which occurred on June 6, 2023. Our payments under the agreements with Honeywell during the period that they were considered a related party amounted to $2 million for the year ended December 31, 2023 and were included in Cost of goods sold, and Selling, general and administrative expenses, in our Consolidated Statements of Operations. As discussed in Note 19, Equity, in order to effect the Transaction, on April 12, 2023 (the "Transaction Date"), the Company entered into separate definitive agreements (the "Series A Preferred Stock Agreements") with each of Centerbridge Partners, L.P. (“Centerbridge”) and funds managed by Oaktree Capital Management, L.P. (“Oaktree”), to effect a series of integrated transactions (collectively, the "Transaction") designed to simplify the Company's capital structure by converting all outstanding shares of Series A Preferred Stock into a single class of Common Stock, subject to certain conditions. Each of Centerbridge and Oaktree is a holder of our Common Stock and appoints a director to our Board of Directors. Mr. Kevin Mahony, who serves as a Senior Managing Director of Centerbridge, and Mr. Steven Tesoriere, who serves as a Managing Director and Co-Portfolio Manager of Oaktree, have been appointed to our Board of Directors as designees of Centerbridge and Oaktree, respectively. As described more fully in Note 19, Equity, in connection with the Transaction, we paid to Centerbridge and Oaktree an aggregate of approximately $570 million for the repurchase of shares of Series A Preferred Stock, plus an aggregate of approximately $10 million and 7,276,036 shares of Common Stock representing the Additional Amounts and Accumulated Dividends in respect of the repurchased shares of Series A Preferred Stock. Additionally, in connection with the conversion of the Series A Preferred Stock that each of Centerbridge and Oaktree held as of the conversion date, we issued to Centerbridge and Oaktree an aggregate of 65,334,277 shares of Common Stock upon the conversion of an equivalent number of shares of Series A Preferred Stock, plus Additional Amounts and Accumulated Dividends of approximately $9 million and 6,819,540 shares of Common Stock. In connection with the conversion of our Series A Preferred Stock, we issued to Honeywell, as a holder of our Series A Preferred Stock, 4,196,330 shares of Common Stock upon the conversion of an equivalent number of shares of Series A Preferred Stock, plus Additional Amounts and Accumulated Dividends of approximately $1 million and 438,009 shares of Common Stock. Additionally, Mr. John Petry, a director on our Board in 2023, serves as Managing Member of Sessa Capital (Master), L.P., which indirectly held shares of our Series A Preferred Stock prior to the conversion. In connection with the conversion of our Series A Preferred Stock, we issued to Sessa Capital and its affiliates, as holder of our Series A Preferred Stock, 16,592,384 shares of Common Stock upon the conversion of an equivalent number of shares of Series A Preferred Stock, plus Additional Amounts and Accumulated Dividends of approximately $2 million and 1,731,900 shares of Common Stock. During 2024, we repurchased from Centerbridge a total of 2,808,988 shares of Common Stock for $25 million under our share repurchase program. During 2025, we also repurchased from Oaktree a total of 7,500,000 shares of Common Stock for $103 million under our share repurchase program. The repurchased shares are held as treasury stock.

Factoring and Notes Receivable

Note 8. Factoring and Notes Receivable

The Company enters into arrangements with financial institutions to sell eligible trade receivables. The receivables are sold without recourse and the Company accounts for these arrangements as true sales. The Company also receives guaranteed bank notes without recourse, in settlement of accounts receivables, primarily in the Asia Pacific region. The Company can hold the bank notes until maturity, exchange them with suppliers to settle liabilities, or sell them to third-party financial institutions in exchange for cash. Bank notes sold to third-party financial institutions without recourse are likewise accounted for as true sales.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Note 2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of the Consolidated Financial Statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates and assumptions are periodically reviewed and the effects of changes are reflected in the Consolidated Financial Statements in the period they are determined to be necessary.

Principles of Consolidation and Combination

The Consolidated Financial Statements include the accounts of Garrett Motion Inc. and all of its subsidiaries in which a controlling financial interest is maintained. We consolidate entities that we control due to ownership of a majority voting interest, and we consolidate variable interest entities when we have variable interests and are the primary beneficiary. Our consolidation policy requires equity investments that we exercise significant influence over but in which we do not have a controlling financial interest to be accounted for using the equity method. Investments through which we are not able to exercise significant influence over the investee and which we do not have readily determinable fair values are accounted for under the cost method. All intercompany transactions and balances are eliminated in consolidation.

Cash and Cash Equivalents

Cash and cash equivalents include cash on hand and highly liquid investments having an original maturity of three months or less.

Restricted Cash

Restricted cash primarily consists of bank deposits pledged as collateral to issue bank notes (refer to Note 8, Factoring and Notes Receivable).

Trade Receivables and Allowance for Doubtful Accounts

Trade accounts receivable are recorded at the invoiced amount as a result of transactions with customers. In accordance with ASC 326, Financial Instruments - Credit Losses, the Company maintains allowances for doubtful accounts for losses as a result of a customer’s inability to make required payments, estimated based on the expected credit losses over the contractual life of the receivables based on days past due as measured from the contractual due date and collection history. The Company also takes into consideration changes in economic conditions that may not be reflected in historical trends (for example, customers in bankruptcy, liquidation or reorganization). Receivables are written-off against the allowance for doubtful accounts when they are determined uncollectible. Such determination includes analysis and consideration of the particular conditions of the account, including time intervals since last collection, customer performance against agreed upon payment plans, solvency of customer and any bankruptcy proceedings.

Transfer of Financial Instruments

Sales and transfers of financial instruments are accounted for under ASC 860, Transfers and Servicing. The Company may discount and sell accounts receivables during the normal course of business. These receivables which are transferred to a third party without recourse to the Company and that meet the criteria of sales accounting as per ASC 860, are excluded from the amounts reported in the Consolidated Balance Sheets. The cash proceeds received from such sales are included in operating cash flows. The expenses associated with the factoring of receivables are recorded within Other expense, net in the Consolidated Statements of Operations.

The Company may also receive bank notes in settlement of accounts receivables, primarily in the Asia Pacific region. Such bank notes are classified as notes receivables under Accounts, notes and other receivables – net in the Consolidated Balance Sheets. The collections of such bank notes are included in operating cash flows and any expenses related to discounting these are included within Other expense, net in the Consolidated Statements of Operations. The Company can hold the bank notes until maturity, exchange them with suppliers to settle liabilities, or sell them to third party financial institutions in exchange for cash.

Inventories

Inventories are stated at the lower of cost, determined on a first-in, first-out basis, including direct material costs and direct and indirect manufacturing costs, or net realizable value. Obsolete inventory is identified based on analysis of inventory for known obsolescence issues. The original equipment inventory on hand in excess of forecasted usage and lack of consumption in the previous 12 months is fully reserved, unless the value of such material is recoverable from either the vendor or the customer.

Property, Plant and Equipment, Net

Property, plant and equipment are recorded at cost less accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful lives of assets, which are 10 to 50 years for buildings and improvements, 2 to 16 years for machinery and equipment, 3 to 10 years for tooling equipment, and 5 to 7 years for software. Maintenance and repairs are expensed as incurred.

Impairment testing of long lived assets is completed by the Company in accordance with ASC 360, Property, Plant and Equipment. The testing is completed when a triggering event occurs, or at least on an annual basis to assess if any impairment triggering events existed during the year. If a triggering event occurs or is identified, the impairment testing is completed using the two-step impairment model. Asset classes are identified and tested for recoverability by comparing the net carrying value of the asset group to the undiscounted net cash flows to be generated from the use and eventual disposition of that asset group. If the carrying amount of an asset group is not recoverable, an impairment loss is recognized if the carrying amount exceeds the fair value. The impairment analysis was completed in 2025 with no triggering events identified.

Leases

Right-of-use (“ROU”) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date of a lease (the “commencement date”) based on the present value of lease payments over the lease term. We determine if an arrangement is a lease at inception. Operating leases are included in Other assets, Accrued liabilities, and Other liabilities in our Consolidated Balance Sheets. Finance leases are included in Property, plant and equipment - net in our Consolidated Balance Sheets. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. We use the implicit rate when readily determinable. The lease ROU asset also includes any lease payments

made and excludes lease incentives. Our lease terms may include options to extend or terminate the lease where it is reasonably certain that we will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Variable lease payments are expensed in the period in which they occur. We have lease agreements with lease and non-lease components, which are generally accounted for separately. For machinery and equipment, we account for the lease and non-lease components as a single lease component. We account for short-term leases by recognizing lease payments in net income on a straight-line basis over the lease term and will not recognize any ROU assets and lease liabilities on the Consolidated Balance Sheet.

Goodwill

Goodwill is subject to impairment testing annually, and whenever events or changes in circumstances indicate that the carrying amount may not be fully recoverable. This testing compares carrying value to fair value of our single reporting unit. The Company recognizes an impairment charge for the amount by which the carrying value of the reporting unit exceeds the reporting unit´s fair value. However, any impairment should not exceed the amount of goodwill allocated to the reporting unit. Because we have a single reporting unit with a negative carrying value, no impairment was recognized.

Warranties and Guarantees

Expected warranty costs for products sold are recognized based on an estimate of the amount that eventually will be required to settle such obligations. These accruals are based on factors such as past experience, length of the warranty and various other considerations. Costs of product recalls, which may include the cost of the product being replaced as well as the customer’s cost of the recall, including labor to remove and replace the recalled part, are accrued as part of our warranty accrual at the time an obligation becomes probable and can be reasonably estimated. These estimates are adjusted from time to time based on facts and circumstances that impact the status of existing claims. For additional information, see Note 23, Commitments and Contingencies.

Sales Recognition

Product sales are recognized when we transfer control of the promised goods to our customer, which is based on shipping terms. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring the promised goods, adjusted for any variable consideration such as price concessions or annual price adjustments as estimated at contract inception. Amounts billed but ultimately expected to be refunded to the customer are recorded as part of the customer pricing reserve within Accrued liabilities on the Consolidated Balance Sheet.

In the sale of products in the OEM channel, the transaction price for these goods is generally equal to the agreed price of each unit and represents the standalone selling price for the unit. In the sale of products in the aftermarket channel, the terms of a contract or the historical business practice can give rise to variable consideration due to, but not limited to, discounts and rebates.

We estimate variable consideration at the most likely amount we will receive from customers and reduce revenues recognized accordingly. We include estimated amounts in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. Our estimates of variable consideration and determination of whether to include estimated amounts in the transaction price are based largely on an assessment of our anticipated performance and all information (historical, current and forecasted) that is reasonably available to us. We adjust our estimate of revenue at the earlier of when the value of consideration we expect to receive changes or when the consideration becomes fixed.

Research, Development and Engineering

Garrett conducts research, development and engineering (“RD&E”) activities which consist primarily of the development of new products and product applications. RD&E costs are included in Cost of goods sold. Customer reimbursements are netted against gross RD&E expenses as they are considered a recovery of cost. RD&E costs are charged to expense as incurred unless the Company has a contractual guarantee of reimbursement from the customer, in which case the related costs are capitalized. Total RD&E expenses, net of customer reimbursements, amounted to $151 million, $161 million and $163 million for the years ended December 31, 2025, 2024 and 2023, respectively. As of December 31, 2025 and 2024, $52 million and $29 million, respectively, of contractually reimbursable costs were capitalized. These amounts are recorded within Other current assets and Other assets in the Consolidated Balance Sheets.

Government Incentives

The Company receives incentives from governmental entities related to expenses, assets, and other activities. The associated terms of the incentives can vary by country. Government incentives are recorded in the financial statements in accordance with their purpose as a reduction of expense, a reduction of asset cost or other operating or non-operating income. Incentives are recognized when there is probable assurance that the Company will comply with the conditions for the incentives and a reasonable expectation that the funds will be received. Government incentives received prior to being earned are recognized as deferred income whereas incentives earned prior to being received are recognized as receivables. The Company recognized government incentives of $18 million, $19 million and $14 million for the years ended December 31, 2025, 2024 and 2023, respectively. These amounts are recorded in Cost of goods sold and Selling, general and administrative expenses in the Consolidated Statements of Operations.

Supplier Financing

The Company has supplier financing arrangements with two third-party financial institutions under which certain suppliers may factor their receivables from Garrett. The Company also enters into arrangements with banking institutions to issue bankers acceptance drafts in settlement of accounts payables, primarily in the Asia Pacific region. The bankers acceptance drafts, or guaranteed bank notes, have a contractual maturity of six months or less, and may be held by suppliers until maturity, transferred to their suppliers, or discounted with financial institutions in exchange for cash. Supplier financing obligations outstanding and guaranteed bank notes outstanding are recorded within Accounts payable. The following table summarizes the activity related to our supplier financing obligations and guaranteed bank notes:


	Supplier Financing Obligations Outstanding		Guaranteed Bank Notes Outstanding
	(Dollars in millions)
Balance at December 31, 2023	$	68	$	193
Obligations added to the program	249		340
Obligations settled	(250)		(386)

Obligations settled	(271)		(326)
Foreign currency translation	(3)		6
Balance at December 31, 2025	$	69	$	158

Environmental Matters

The Company records liabilities for environmental assessments and remediation activities in the period in which it is probable that a liability has been incurred and the amount of that liability can be reasonably estimated. Estimated costs are recorded at undiscounted amounts, based on experience and assessments and are regularly evaluated. To the extent that the required remediation procedures change, or additional contamination is identified, the Company’s estimated environmental liabilities may also change. The liabilities are recorded in Accrued liabilities and Other liabilities in the Consolidated Balance Sheets.

Stock-Based Compensation

The principal awards issued under our stock-based compensation plans, which are described in Note 21, Stock-Based Compensation, are performance stock units and restricted stock units. The cost for such awards is measured at the grant date based on the fair value of the award. Compensation expense is recognized over the requisite service periods (generally the vesting period of the equity award) based on the Company's best estimate of ultimate performance against the award targets, and is included in Selling, general and administrative expenses in the Consolidated Statements of Operations. The Company accounts for forfeitures as they occur.

Pension Benefits

We sponsor defined benefit pension plans covering certain employees, primarily in Switzerland, the U.S. and Ireland. For such plans, we are required to disaggregate the service cost component of net benefit costs and report those costs in the same line item or items in the Consolidated Statements of Operations as other compensation costs arising from services rendered by the pertinent employees during the period. The other non-service components of net benefit costs are required to be presented separately from the service cost component. We record the service cost component of Pension expense (income) in Cost of goods sold or Selling, general and administrative expenses. The remaining components of net benefit costs within Pension expense (income), primarily interest costs and assumed return on plan assets, are recorded in Non-operating expense (income). We recognize net actuarial gains or losses in excess of 10% of the greater of the fair value of plan assets or the plans’ projected benefit obligation (the corridor) annually in the fourth quarter each year (the “MTM Adjustment”). The MTM Adjustment is recorded in Non-operating expense (income).

Foreign Currency Translation

Assets and liabilities of subsidiaries operating outside the United States with a functional currency other than U.S. Dollars are translated into U.S. Dollars using year-end exchange rates. Sales, costs and expenses are translated at the average exchange rates in effect during the year. Foreign currency translation gains and losses are included as a component of Accumulated other comprehensive income ("AOCI").

Derivative Financial Instruments

We minimize our risks from foreign currency exchange rate fluctuations through our normal operating and financing activities and, when deemed appropriate, through the use of derivative financial instruments. Derivative financial instruments are used to manage risk and are not used for trading or other speculative purposes. Derivative financial instruments that qualify for hedge accounting must be designated and effective as a hedge of the identified risk exposure at the inception of the contract. Accordingly, changes in fair value of the derivative contract must be highly correlated with changes in fair value of the underlying hedged item at inception of the hedge and over the life of the hedge contract.

All derivatives are recorded on the Consolidated Balance Sheets as assets or liabilities and measured at fair value. For derivatives designated as cash flow hedges, the effective portion of the changes in fair value of the derivatives are recorded in AOCI and subsequently recognized in earnings when the hedged items impact earnings. Cash flows of such derivative financial instruments are classified consistent with the underlying hedged items. For derivatives designated as net investment hedges, provided the hedging relationship is highly effective, the changes in fair value of the derivatives are recorded in AOCI until the net investment is liquidated or sold.

Income Taxes

We account for income taxes pursuant to the asset and liability method which requires us to recognize current tax liabilities or receivables for the amount of taxes we estimate are payable or refundable for the current year and deferred tax assets and liabilities for the expected future tax consequences attributable to temporary differences between the financial statement carrying amounts and their respective tax bases of assets and liabilities and the expected benefits of net operating loss and credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in operations in the period enacted. A valuation allowance is provided when it is more likely than not that a portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income and the reversal of deferred tax liabilities during the period in which related temporary differences become deductible.

We reclassify taxes from AOCI to earnings as the items to which the tax effects relate are similarly reclassified.

Earnings per share

Basic earnings per share for the years ended December 31, 2025, 2024 and 2023 are calculated using the two-class method. In 2025 and 2024, the deferred stock units related to the stock-based compensation plan contain non-forfeitable rights to dividends and are considered as participating securities, while in 2023 our Series A Preferred Stock was considered a participating security prior to its conversion into Common Stock and cancellation pursuant to the Transaction. The two-class method requires an allocation of earnings to all securities that participate in dividends with common shares

to the extent that each such security may share in the Company's earnings. Basic earnings per share are calculated by dividing undistributed earnings allocated to Common Stock by the weighted average number of common shares.

Diluted earnings per share for the years ended December 31, 2025 and 2024 are calculated by applying the two-class method for participating securities and then incorporating the dilutive effects of other potential common shares, determined using methods such as the treasury stock method, to arrive at the most dilutive EPS. Diluted earnings per share for the year ended December 31, 2023 are calculated by evaluating the more dilutive impact of both the two-class method and the if-converted method. The two-class method uses net income available to common shareholders and assumes conversion of all potential shares other than the participating securities. The if-converted method uses net income and assumes conversion of all potential shares including the participating securities. See Note 22, Earnings Per Share for further details.

Related Party Transactions

We contract with Trane Technologies ("Trane") for the occasional purchase of goods and services. Mr. Paul Camuti, a director on our Board of Directors, served as an executive officer of Trane through December 31, 2024, and was considered a related party until that time. Our payments under the agreements with Trane amounted to $1 million for the year ended December 31, 2024, and were included in Cost of goods sold in our Consolidated Statement of Operations. The liability balance due to Trane as of December 31, 2024, was immaterial.

We lease certain facilities and receive property maintenance services from Honeywell International ("Honeywell") which, as of April 30, 2021 was the owner of our Series B Preferred Stock that has since been fully redeemed by the Company, is a holder of our Common Stock and was also a holder of our Series A Preferred Stock prior to the Transaction, as discussed below and in Note 19, Equity. We also contract with Honeywell for the occasional purchase of certain goods and services. Lease and service agreements were made at commercial terms prevalent in the market at the time they were executed. Honeywell is not considered a related party subsequent to the Transaction, which occurred on June 6, 2023.

Our payments under the agreements with Honeywell during the period that they were considered a related party amounted to $2 million for the year ended December 31, 2023 and were included in Cost of goods sold, and Selling, general and administrative expenses, in our Consolidated Statements of Operations.

As discussed in Note 19, Equity, in order to effect the Transaction, on April 12, 2023 (the "Transaction Date"), the Company entered into separate definitive agreements (the "Series A Preferred Stock Agreements") with each of Centerbridge Partners, L.P. (“Centerbridge”) and funds managed by Oaktree Capital Management, L.P. (“Oaktree”), to effect a series of integrated transactions (collectively, the "Transaction") designed to simplify the Company's capital structure by converting all outstanding shares of Series A Preferred Stock into a single class of Common Stock, subject to certain conditions. Each of Centerbridge and Oaktree is a holder of our Common Stock and appoints a director to our Board of Directors. Mr. Kevin Mahony, who serves as a Senior Managing Director of Centerbridge, and Mr. Steven Tesoriere, who serves as a Managing Director and Co-Portfolio Manager of Oaktree, have been appointed to our Board of Directors as designees of Centerbridge and Oaktree, respectively. As described more fully in Note 19, Equity, in connection with the Transaction, we paid to Centerbridge and Oaktree an aggregate of approximately $570 million for the repurchase of shares of Series A Preferred Stock, plus an aggregate of approximately $10 million and 7,276,036 shares of Common Stock representing the Additional Amounts and Accumulated Dividends in respect of the repurchased shares of Series A Preferred Stock. Additionally, in connection with the conversion of the Series A Preferred Stock that each of Centerbridge and Oaktree held as of the conversion date, we issued to Centerbridge and Oaktree an aggregate of 65,334,277 shares of Common Stock upon the conversion of an equivalent number of shares of Series A Preferred Stock, plus Additional Amounts and Accumulated Dividends of approximately $9 million and 6,819,540 shares of Common Stock.

In connection with the conversion of our Series A Preferred Stock, we issued to Honeywell, as a holder of our Series A Preferred Stock, 4,196,330 shares of Common Stock upon the conversion of an equivalent number of shares of Series A Preferred Stock, plus Additional Amounts and Accumulated Dividends of approximately $1 million and 438,009 shares of Common Stock.

Additionally, Mr. John Petry, a director on our Board in 2023, serves as Managing Member of Sessa Capital (Master), L.P., which indirectly held shares of our Series A Preferred Stock prior to the conversion. In connection with the conversion of our Series A Preferred Stock, we issued to Sessa Capital and its affiliates, as holder of our Series A Preferred Stock, 16,592,384 shares of Common Stock upon the conversion of an equivalent number of shares of Series A Preferred Stock, plus Additional Amounts and Accumulated Dividends of approximately $2 million and 1,731,900 shares of Common Stock.

During 2024, we repurchased from Centerbridge a total of 2,808,988 shares of Common Stock for $25 million under our share repurchase program. During 2025, we also repurchased from Oaktree a total of 7,500,000 shares of Common Stock for $103 million under our share repurchase program. The repurchased shares are held as treasury stock.

Long-term Debt and Credit Agreements

Note 15. Long-term Debt and Credit Agreements

Long Term Debt

Senior Notes

On May 21, 2024, Garrett Motion Holdings Inc. and Garrett LX I S.à.r.l. (the "Issuers"), wholly owned subsidiaries of the Company, completed an offering of $800 million in aggregate principal amount of 7.75% Senior Unsecured Notes due 2032 (the "2032 Senior Notes"). The 2032 Senior Notes mature on May 31, 2032. The Company incurred $12 million of debt issuance costs, which have been capitalized and will be amortized on a straight-line basis.

The 2032 Senior Notes are guaranteed by the Company and each of the Company's wholly owned subsidiaries that guarantee obligations under the existing Credit Agreement (as defined below), subject to certain exceptions. The proceeds

from the sale of the 2032 Senior Notes, together with cash on hand, were used to repay approximately $800 million of term loan indebtedness, as described below, and to pay related fees and expenses.

Term Loans

On January 30, 2025, the Company entered into the Restatement Agreement, which amended and restated the Existing Credit Agreement. Pursuant to the Restatement Agreement, the Company refinanced in full its $692 million U.S. Dollar term loan facility (the "2021 Dollar Term Facility") under the Existing Credit Agreement with a new $692 million term loan (the "2025 Dollar Term Facility") in an aggregate principal amount of $692 million. The 2025 Dollar Term Facility will mature on January 30, 2032.

The principal outstanding and carrying amounts of our long-term debt as of December 31, 2025 and 2024 are as follows:


			December 31,
(Dollars in millions)	Maturity Date	Interest Rate	2025		2024
2021 Dollar Term Facility	April 30, 2028	SOFR plus 275 bps	$	—	$	692
2025 Dollar Term Facility	January 30, 2032	SOFR plus 200 bps	637		—
2032 Senior Notes	May 31, 2032	7.75%	800		800
Other			2		1
Total principal outstanding			1,439		1,493
Less: unamortized deferred financing costs			(21)		(22)
Less: current portion of long-term debt			(7)		(7)
Total long-term debt			$	1,411	$	1,464

The following table summarizes the minimum scheduled principal repayments of long-term debt as of December 31, 2025:


	December 31,
	(Dollars in millions)
2026	$	7
2027	7
2028	9
2029	7
2030	7
Thereafter	1,402
Total payments on long-term debt	$	1,439

New Revolving Facility and Letters of Credit

Also on January 30, 2025, pursuant to the Restatement Agreement, the Company replaced its existing $600 million revolving commitments under the Existing Credit Agreement with new revolving commitments under the Credit Agreement in an aggregate principal amount of $630 million (the "New Revolving Facility" and, together with the New Term Loans, the "Credit Facilities"). The maturity date of the New Revolving Facility is January 30, 2030.

Under the New Revolving Facility, the Company may use up to $125 million for the issuance of letters of credit to its subsidiaries. Letters of credit are available for issuance under the Credit Agreement on terms and conditions customary for financings of this kind, which issuances will reduce availability under the New Revolving Facility. As of December 31, 2025, the Company had no borrowings outstanding under the New Revolving Facility, no outstanding letters of credit, and available borrowing capacity of $630 million. As of December 31, 2024, the Company had no borrowings outstanding under the Revolving Facility, no outstanding letters of credit, and available borrowing capacity of $600 million.

Separate from the New Revolving Facility, the Company has a bilateral letter of credit facility with outstanding letters of credit of $10 million and $8 million at December 31, 2025 and 2024, respectively. The letters of credit typically support customs arrangements and other obligations at its local affiliates.

Amendments to the Credit Agreement

On August 6, 2025, the Company entered into Amendment No. 1 (the "First Amendment") to the Credit Agreement, which reduced the Applicable Rate to the Adjusted Term SOFR Rate plus 2.00% per annum in the case of Term Benchmark Loans and the Alternate Base Rate plus 1.00% per annum in the case of ABR Loans.

Security

The Credit Facilities are secured on a first-priority basis by: (i) a perfected security interest in the equity interests of each direct material subsidiary of each guarantor under the Credit Facilities and (ii) perfected security interests in, and mortgages on, substantially all tangible and intangible personal property and material real property of each of the guarantors under the Credit Facilities, subject, in each case, to certain exceptions and limitations, including the agreed guaranty and security principles.

Interest Rate and Fees

The 2032 Senior Notes bear interest at a rate of 7.75% per annum. Interest on the 2032 Senior Notes is payable semi-annually in arrears on May 31 and November 30 of each year, commencing on November 30, 2024.

The 2025 Dollar Term Facility is subject to an interest rate equal to, at the Company's option, the Adjusted Term SOFR Rate plus 2.00% per annum in the case of Term Benchmark Loans and the Alternate Base Rate plus 1.00% per annum in the case of ABR Loans.

The New Revolving Facility, when drawn, will bear interest at a rate equal to the applicable benchmark plus an applicable margin that varies based on the Company's leverage ratio. The applicable margin for revolving borrowings ranges from 2.25% to 1.75% per annum in the case of Term Benchmark Loans and 1.25% to 0.75% per annum in the case of ABR Loans.

Accordingly, the interest rates for the Credit Facilities will fluctuate during the term of the Credit Agreement based on changes in the ABR, SOFR and other applicable benchmark rates or future changes in our leverage ratio. Interest payments with respect to the Term Loan Facilities are required either on a quarterly basis (for ABR loans) or at the end of each interest period (for SOFR loans) or, if the duration of the applicable interest period exceeds three months, then every three months.

In addition to paying interest on outstanding borrowings under the Revolving Facility, the Company is required to pay a quarterly commitment fee based on the unused portion of the New Revolving Facility, which is determined by our leverage ratio and ranges from 0.25% to 0.50% per annum.

Prepayments

2032 Senior Notes

The Issuers may redeem some or all of the 2032 Senior Notes at its option prior to May 31, 2027, at a redemption price equal to 100% of the principal amount of the 2032 Senior Notes redeemed, plus a customary "make-whole" premium, plus accrued and unpaid interest excluding, the redemption date.

At any time prior to May 31, 2027, the Issuers may also redeem up to 40% of the aggregate principal amount of the 2032 Senior Notes with funds in an aggregate amount not to exceed the net cash proceeds from certain equity offerings at a redemption price equal to 107.750% of principal plus accrued and unpaid interest. The issuers may redeem the 2032 Senior Notes at its option, in whole at any time or in part from time to time, at the following redemption prices:

•from May 31, 2027 to May 30, 2028: Redemption Price equal to 103.875% of principal plus accrued and unpaid interest;

•from May 31, 2028 to May 30, 2029: Redemption Price equal to 101.938% of principal plus accrued and unpaid interest; and

•from May 31, 2029 and Thereafter: Redemption Price equal to 100% of principal plus accrued and unpaid interest

Additionally, the Issuers may redeem all, but not part, of the 2032 Senior Notes upon the occurrence of specified tax events as described in the indenture.

Term Loans

The Company is obligated to make quarterly principal payments throughout the term of the 2025 Dollar Term Facility according to the amortization provisions in the Credit Agreement. Such payments may be reduced from time to time in accordance with the terms of the Credit Agreement as a result of the application of loan prepayments made by us, if any, prior to the scheduled date of payment thereof.

We may voluntarily prepay borrowings under the Credit Agreement without premium or penalty, subject to a 1.00% prepayment premium in connection with certain repricing events in connection with the 2025 Dollar Term facility during the period from the Credit Agreement Closing Date to the date that is six months following the First Amendment Closing Date and customary "breakage” costs with respect to SOFR and EURIBOR loans. We may also reduce the commitments under the New Revolving Facility, in whole or in part, in each case, subject to certain minimum amounts and increments.

The Credit Agreement also contains certain mandatory prepayment provisions in the event that we incur certain types of indebtedness, receive net cash proceeds from certain non-ordinary course asset sales or other dispositions of property or, starting with the fiscal year ending on December 31, 2024, 0.50% of excess cash flow on an annual basis (with step-downs to 25% and 0% subject to compliance with certain leverage ratios), in each case subject to terms and conditions customary for financings of this kind.

During the year ended December 31, 2024, we made early debt repayments totaling $985 million on our €450 million secured first-lien Euro term loan facility and our $700 million secured first-lien U.S. Dollar term loan facility. Both term loans were fully repaid as of December 31, 2024. The early repayments resulted in incremental amortization of debt issuance costs of $27 million, included within Interest expense in the Consolidated Statement of Operations.

During the year ended December 31, 2025, we made an early debt repayment of $50 million on our 2025 Dollar Term Facility. The early repayment resulted in incremental amortization of debt issuance costs of $1 million, included within Interest expense in the Consolidated Statement of Operations.

Representations and Warranties

The Credit Agreement contains certain representations and warranties (subject to certain agreed qualifications) that are customary for financings of this kind.

Certain Covenants

2032 Senior Notes

The 2032 Senior Notes contain certain covenants that limit the ability of the Company and its restricted subsidiaries to incur certain additional debt, incur certain liens securing debt, pay certain dividends or make other restricted payments, make certain investments, make certain asset sales, and enter into certain transactions with affiliates. These covenants are subject to a number of exceptions, limitations, and qualifications as set forth in the 2032 Senior Notes indenture. Additionally, the indenture contains certain change of control provisions that, under certain conditions, would require the Company to make an offer to repurchase all of the outstanding 2032 Senior Notes at a price equal to 101% of the aggregate principal amount, plus accrued and unpaid interest. The indenture also contains customary events of default.

Term Loans

The Credit Agreement contains certain affirmative and negative covenants customary for financing of this type. The New Revolving Facility also contains a financial covenant requiring the maintenance of a consolidated total leverage ratio of not greater than 4.7 times as of the end of each fiscal quarter if, on the last day of any such fiscal quarter, the aggregate amount of loans and letters of credit (excluding backstopped or cash collateralized letters of credit and other letters of credit with an aggregate face amount not exceeding $30 million) outstanding under the New Revolving Facility exceeds 35% of the aggregate commitments thereunder.

As of December 31, 2025, the Company was in compliance with all its financing covenants.

Defined Benefit Pension and Post-Employment Plans

Note 24. Defined Benefit Pension and Post-Employment Plans

We sponsor several funded U.S. and non-U.S. defined benefit pension and post-employment plans. Pension benefits for many of our U.S. employees are provided through a non-contributory, qualified defined benefit plan. We also sponsor defined benefit pension plans in Switzerland and Ireland. Other pension and post-employment plans outside of the U.S. are not material to the Company either individually or in the aggregate.

The following tables summarize the balance sheet impact, including the benefit obligations, assets and funded status associated with our pension and post-employment plans.

The main actuarial assumptions used in determining the benefit obligations and net periodic benefit (income) cost for the benefit plans are presented in the following table as weighted averages.


	Pension and Post-Employment Benefits
	U.S. Plans						Non-U.S. Plans
	2025		2024		2023		2025		2024		2023
Actuarial assumptions used to determine benefit obligations as of December 31:
Discount rate	5.49	%	5.68	%	5.02	%	2.68	%	2.21	%	2.36	%
Expected annual rate of compensation increase	3.00	%	3.00	%	3.00	%	1.92	%	2.11	%	2.38	%
Interest credited to accounts (1)	—	%	—	%	—	%	2.50	%	2.65	%	2.65	%
Actuarial assumptions used to determine net periodic benefit (income) cost for years ended December 31:
Discount rate—benefit obligation	5.68	%	5.02	%	5.21	%	2.21	%	2.36	%	2.91	%
Discount rate—service cost	5.67	%	5.05	%	5.23	%	2.21	%	2.36	%	2.91	%

(1)Only applicable to the defined benefit pension plan in Switzerland.

The discount rates for the pension and post-employment plans reflect the current rates at which the associated liabilities could be settled at the measurement date of December 31, 2025. To determine the discount rates, we use a modeling process that involves matching the expected cash outflows of our benefit plans to a yield curve constructed from a portfolio of high quality, fixed-income debt instruments. We use the single weighted-average yield of this hypothetical portfolio as a discount rate benchmark.

For both our U.S. and non-U.S. defined benefit pension and post-employment plans, we estimate the service and interest cost components of net period benefit (income) cost by utilizing a full yield curve approach in the estimation of these cost components by applying the specific spot rates along the yield curve used in the determination of the benefit obligation to their underlying projected cash flows. This approach provides a more precise measurement of service and interest costs by improving the correlation between projected cash flows and their corresponding spot rates.

For non-U.S. benefit plans, actuarial assumptions reflect economic and market factors relevant to each country.

The following amounts relate to our pension plans with accumulated benefit obligations exceeding the fair value of plan assets.


	December 31,
	U.S. Plans				Non-U.S. Plans
	2025		2024		2025		2024
	(Dollars in millions)
Projected benefit obligation	$	—	$	—	$	17	$	85
Accumulated benefit obligation	—		—		14		84
Fair value of plan assets	—		—		8		78

Our U.S. pension asset investment strategy focuses on maintaining a diversified portfolio using various asset classes in order to achieve market exposure and diversification on a risk adjusted basis. Our target allocations are as follows: 91% liability-hedging fixed income investments, 8% global equity securities, and 1% real estate investments. Fixed income investments include corporate and government issues with a target duration close to that of the plan liability. Global equity securities include mutual funds that invest in companies located both inside and outside the United States. The real estate fund invests in real estate investment trusts – companies that purchase office buildings, hotels and other real estate property. Our assets are reviewed on a daily basis to ensure that we are within the targeted asset allocation ranges and, if necessary, asset balances are adjusted back within target allocations.

Our non-U.S. pension and post-employment assets are typically managed by decentralized fiduciary committees. Our non-U.S. investment policies are different for each country as local regulations, funding requirements, and financial and tax considerations are part of the funding and investment allocation process in each country.

The fair values of both our U.S. and non-U.S. pension and post-employment plans assets by asset category are as follows:

Equity funds, corporate bond funds, government bond funds, real estate funds, swap funds and short-term investments are valued either by bids provided by brokers or dealers or quoted prices of securities with similar characteristics. Other includes private equity and hedge funds. These investments are valued at estimated fair value based on quarterly financial information received from the investment advisor and/or general partner.

Our general funding policy for qualified defined benefit pension plans is to contribute amounts at least sufficient to satisfy regulatory funding standards. We were not required to make any contributions to our U.S. pension plan in 2025. In 2025, contributions of $6 million were made to our non-U.S. pension plans to satisfy regulatory funding requirements. In 2026, we expect to make contributions of cash and/or marketable securities of approximately $5 million to our non-U.S. pension plans to satisfy regulatory funding standards. Contributions for both our U.S. and non-U.S. pension and post-employment plans do not reflect benefits paid directly from Company assets.

Benefit payments, including amounts to be paid from Company assets, and reflecting expected future service, as appropriate, are expected to be paid as follows:

Cybersecurity Risk Management, Strategy, and Governance [Line Items]
Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]	Risk Management and Strategy Our cybersecurity objective is to protect against data privacy breaches, information theft, and external and insider cyber threats through the use of a combination of cyber technologies, policies, and procedures. We have processes to identify, assess, monitor and mitigate material risks from cybersecurity threats, which are part of the Company’s overall enterprise risk management ("ERM") process and have been embedded in the Company’s operating procedures, internal controls and information systems. To that end, we take a holistic approach to securing our data and business systems from attack, compromise or loss. The Company has cybersecurity capability that is managed by a dedicated Chief Information Security Officer (“CISO”) whose team is responsible for leading the Company-wide cybersecurity strategy, policy, standards, architecture, and processes. The Security Operations Center ("SOC") provides visibility across all information technology assets and includes proactive cyber security threat detection technology to facilitate the identification of misconfigurations to mitigate threats and prevent data loss. As part of the Company’s holistic approach to cybersecurity, we have implemented programs and technology associated with threat hunting, vulnerability scanning, and threat detection and response technology. As part of its cybersecurity risk management, the Company delivers specific education to the organization on how to identify potential cybersecurity risks and protect the Company’s resources and information. This training is mandatory for all employees globally on a regular basis and may be supplemented by various testing initiatives including periodic phishing tests. The Company uses third-party expertise for periodic effectiveness testing of its prevention, detection, and response capabilities. The Company also requires all third-party service providers to meet specific cybersecurity requirements, including risk assessment and monitoring activities. In addition, third-party service providers with access to the Company's network have additional obligations including a requirement to undertake cybersecurity training. While Garrett focuses heavily on prevention and detection, response and recovery plans, service agreements and partner engagements are in place should there be a need for us to respond to a cybersecurity attack. The Company's response process includes identifying the incident; notifying the executive team, activating the crisis team, assessing the business risk and materiality of the incident; managing the recovery of operations; and performing a post-incident analysis. The Company maintains business continuity and disaster recovery plans. The Company also engages in cyber crisis response simulation to assess our incident response ability and effectiveness. No cybersecurity incidents have occurred that materially affected, or are reasonably likely to materially affect, the Company, including its business strategy, results of operations or financial condition during the year ended December 31, 2025. Notwithstanding the extensive approach we take to cybersecurity, we may not be successful in preventing or mitigating a cybersecurity incident that could have a material adverse effect on us in the future. See Item 1A. "Risk Factors" for a discussion of cybersecurity risks.

(1) State taxes in Michigan and Indiana make up the majority (greater than 50 percent) of the tax effect in this category.

(2) Amounts reflected as net of related foreign tax credits.

The effective tax rate increased by 3.1 percentage points in 2025 compared to 2024. The increase was primarily due to additional unrecognized tax benefits in Switzerland and China as well as prior year benefits associated with the release

of valuation allowance related to deferred tax assets in Brazil (net of U.S. branch taxes) and prior year benefits associated with statute of limitation expiration and settlement of audits in Switzerland and Korea. These increases were partially offset by the revaluation of deferred tax assets related to intellectual property transferred within China which was subject to tax at different rates.

The effective tax rate decreased by 7.0 percentage points in 2024 compared to 2023. The decrease was primarily due to releases of reserves due to statute of limitation expirations and settlements with taxing authorities and release of valuation allowance related to deferred tax assets in Brazil (net of U.S. branch taxes). In addition, there was prior year expense due to rate change impact on deferred tax assets attributable to the certification by the Chinese government of the High and New Technology Enterprise status of the Company’s China operations, which reduced the tax rate to 15% for the respective entity. These increases were partially offset by prior year tax benefits in Switzerland due to law changes (net of valuation allowance) and in Korea for prior year tax settlements.

Deferred tax assets (liabilities)

The tax effects of temporary differences and tax carryforwards which give rise to future income tax benefits and payables are as follows:


	December 31,
	2025		2024
	(Dollars in millions)
Deferred tax assets:
Intangibles and fixed assets	$	114	$	112

Accruals and reserves	31		29
Net operating losses and other tax attribute carryforwards	42		34
Outside basis differences	1		29
Other	94		70
Total deferred tax assets	282		274
Valuation allowance	(37)		(29)
Net deferred tax assets	$	245	$	245
Deferred tax liabilities:
Outside basis differences	$	(41)	$	(18)
Other	(26)		(45)
Total deferred tax liabilities	(67)		(63)
Net deferred tax asset	$	178	$	182

As of December 31, 2025, the Company had foreign net operating loss carryforwards of approximately $67 million with the majority in the below jurisdictions:


Jurisdiction	Expiration Period	Net Operating Loss Carryforwards
		(Dollars in millions)
Brazil	Indefinite	$	54
Luxembourg	2039	10

Other	Various	3
		$	67

We also have net operating loss carryforwards in certain U.S. state jurisdictions, the tax effect of which is not significant.

We maintain a valuation allowance of $37 million against a portion of total deferred tax assets. In the event we determine that we will not be able to realize our net deferred tax assets in the future, we will reduce such amounts through an increase to tax expense in the period such determination is made. Conversely, if we determine that we will be able to

realize net deferred tax assets in excess of the carrying amounts, we will decrease the recorded valuation allowance through a reduction to tax expense in the period that such determination is made. Our valuation allowance increased $8 million from last year. Our balance sheet presents a deferred tax asset of $210 million and a deferred tax liability of $32 million after considering jurisdictional netting.

The Company does not intend to permanently reinvest the undistributed earnings of our foreign subsidiaries and have recorded a deferred tax liability, mainly consisting of withholding taxes, of $23 million as of December 31, 2025.

The following table summarizes the activity related to the Company’s uncertain tax positions (excluding interest and penalties and related tax attributes):


	December 31,
	2025		2024		2023
	(Dollars in millions)
Change in unrecognized tax benefits:

Expiration of the statute of limitations for the assessment of taxes	(11)		(17)		(8)

Foreign currency translation	1		(2)		—
Balance at end of year	$	55	$	48	$	66

As of December 31, 2025, 2024, and 2023 there were $55 million, $48 million, and $66 million, respectively, of unrecognized tax benefits that, if recognized, would be recorded as a component of tax expense.

Estimated interest and penalties related to uncertain tax benefits are classified as a component of tax expense in the Consolidated Statements of Operations and totaled $4 million of expense, $2 million of benefit, and $5 million of expense for the years ended December 31, 2025, 2024, and 2023, respectively. Accrued interest and penalties were $36 million, $32 million, and $34 million, as of December 31, 2025, 2024, and 2023, respectively.

We are currently under audit in multiple jurisdictions, primarily India for tax years 2022 through 2024 and U.S. for tax years 2018 through 2020. Based on the outcome of these examinations, or as a result of the expiration of statutes of limitations for specific jurisdictions, it is possible that certain unrecognized tax benefits for tax positions taken on previously filed tax returns will significantly change from those recorded as liabilities in our financial statements.

Earnings Per Share [Abstract]

Earnings Per Share

Note 22. Earnings Per Share

Basic earnings per share ("EPS") for the years ended December 31, 2025, and 2024, and 2023 is computed using the two-class method. In 2025 and 2024, the DSUs related to the stock-based compensation plan contain non-forfeitable rights to dividends and are considered as participating securities, while in 2023 our Series A Preferred Stock was considered a participating security prior to its conversion into Common Stock and cancellation pursuant to the Transaction. The two-

class method requires an allocation of earnings to all securities that participate in dividends with common shares to the extent that each such security may share in the Company's earnings. Basic EPS is then calculated by dividing undistributed earnings allocated to common stock by the weighted average number of common shares outstanding for the period. Under the two-class method, the impact of these participating securities was immaterial for the years ended December 31, 2025 and 2024.

Diluted EPS for the years ended December 31, 2025 and 2024 is calculated by applying the two-class method for participating securities and then incorporating the dilutive effect of other potential common shares, determined using methods such as the treasury stock method, to arrive at the most dilutive EPS.

Diluted EPS for the year ended December 31, 2023 was calculated by evaluating the impact of both the two-class method and the if-converted method. The two-class method uses net income available to common shareholders and assumes conversion of all potential shares other than the participating securities. The if-converted method uses net income and assumes conversion of all potential shares including the participating securities. Diluted EPS for the year ended December 31, 2023 was disclosed under the two-class method.

The details of the EPS calculations for the years ended December 31, 2025, 2024 and 2023 are as follows:


	Year Ended December 31
	2025		2024		2023

For the periods where a net loss attributable to common shareholders is present, dilutive securities have been excluded from the calculation of diluted net loss per share attributable to common stockholders as including them would have been anti-dilutive. For the year ended December 31, 2023, the weighted-average number of unvested RSUs and other contingently issuable shares excluded from the computations was 1,490,117 shares.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Financial Instruments and Fair Value Measures

Note 17. Financial Instruments and Fair Value Measures

Credit and Market Risk

We continually monitor the creditworthiness of our customers to which we grant credit terms in the normal course of business. The terms and conditions of our credit sales are designed to mitigate or eliminate concentrations of credit risk with any single customer.

Foreign Currency Risk Management

The Company is exposed to market risks from changes in currency exchange rates. These exposures may impact future earnings and/or operating cash flows. Our exposure to market risk for changes in foreign currency exchange rates arises from international financing activities between subsidiaries, foreign currency denominated monetary assets and liabilities and transactions arising from international trade.

We hedge currency exposures with natural offsets to the fullest extent possible and, once these opportunities have been exhausted, through foreign currency exchange forward contracts. The forward currency exchange contracts are intended to mitigate exposure to foreign exchange rate volatility and the associated impact on earnings related to forecasted foreign currency commitments. Certain of these forward currency exchange contracts are designated as cash flow hedges, whereby the gains and losses on these derivatives are recorded in AOCI until the underlying transactions are recognized in earnings.

As of December 31, 2025 and 2024, we had outstanding designated and undesignated forward currency exchange contracts with aggregate gross notional amounts of $1,374 million and $928 million, respectively, to hedge foreign currencies, principally the U.S. Dollar, Swiss Franc, British Pound, Euro, Chinese Yuan, Japanese Yen, Mexican Peso, New Romanian Leu, Czech Koruna, Australian Dollar and Korean Won.

The Company uses fixed-to-fixed cross-currency swap contracts to mitigate the foreign currency risk on its 2032 Senior Notes. The cross-currency swap contracts are designated as cash flow hedges, with changes in the fair value of the derivatives recorded in AOCI and reclassified into earnings based upon changes in the spot rate remeasurement of the underlying debt. The Company also uses cross-currency swap contracts to hedge net investments in foreign subsidiaries. These cross-currency swap contracts are designated as net investment hedges, and the gains and losses on these derivatives are recorded in AOCI until the net investment is liquidated or sold.

Interest Rate Risk Management

The Company is also exposed to market value risk associated with interest rate fluctuations on its variable rate term loan debt. To manage interest rate exposure, the Company enters into interest rate swap contracts. Certain of these interest rate swap contracts are designated as cash flow hedges, whereby the gains and losses on these derivatives are recorded in AOCI until the underlying transactions are recognized in earnings.

Fair Value of Financial Instruments

The FASB’s accounting guidance 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 (exit price). Financial and nonfinancial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The following table sets forth the Company’s financial assets and liabilities that were accounted for at fair value on a recurring basis as of December 31, 2025 and 2024:


					Fair Value
	Notional Amounts				Assets					Liabilities
	December 31, 2025		December 31, 2024		December 31, 2025		December 31, 2024			December 31, 2025		December 31, 2024

Cash Flow Hedges

During 2023, the Company entered into float-to-fixed interest rate swap contracts with an aggregate notional amount of $200 million and maturities in July 2024 and October 2024. The Company also entered into a float-to-fixed cross-currency swap contract comprised of an amortizing swap with an aggregate notional amount of €280 million ($300 million) and notional exchanges in June 2026, June 2027, and June 2028. The interest rate swap and cross-currency swap contracts were early settled in 2024, resulting in net gains of $18 million recorded to Interest expense and a $4 million loss recorded to Non-operating expense in the Consolidated Statement of Operations.

During 2024, in order to mitigate foreign currency risk on its 2032 Senior Notes, the Company entered into fixed-to-fixed cross-currency swap contracts with an aggregate notional amount of €507 million ($550 million) and notional exchanges in May 2027, May 2028, May 2029 and May 2030. Changes in the fair value of the cross-currency swap contracts are recognized in AOCI and reclassified to Non-operating income in the Consolidated Statement of Operations, based upon changes in the spot rate remeasurement of the underlying debt. The net interest settlements on the cross-currency swap contract are recorded in Interest expense in the Consolidated Statements of Operations.

In 2025, the Company entered into float-to-fixed interest rate swap contracts with an aggregate notional amount of $675 million and maturities in January 2028, January 2029, January 2030 and January 2031, of which an interest rate swap contract with a notional amount of $50 million was early settled during the year. Changes in the fair value of the interest rate swap contracts are recorded in AOCI and will be reclassified to Interest expense in the Consolidated Statement of Operations upon maturity. Amounts recognized related to the early settlement of the interest rate swap contract during the year were immaterial.

The Company also has outstanding forward currency exchange contracts with maturities up to 18 months and an aggregate notional amount of $637 million and $331 million as of December 31, 2025 and 2024, respectively. These forward currency exchange contracts have been designated as cash flow hedges to mitigate foreign currency exposures

primarily on our inventory purchases and manufacturing costs. The gains and losses on the forward currency exchange contracts are recorded in AOCI and reclassified to Cost of goods sold in the Consolidated Statement of Operations when the underlying transactions are recognized in earnings.

All of the Company’s cash flow hedges are assessed as highly effective.

Net Investment Hedges

The Company has designated cross-currency swaps with an aggregate notional amount of €1,157 million ($1,225 million) and €858 million ($965 million) as of December 31, 2025 and 2024, respectively, as net investment hedges of the Company’s Euro-denominated operations. In 2025, a cross-currency swap contract with a notional amount of €224 million ($265 million) was early settled. The fair values of the net investment hedges were net liabilities of $124 million and net assets of $70 million as of December 31, 2025 and 2024, respectively. No ineffectiveness has been recorded on the net investment hedges.

Non-Designated Derivatives

As of December 31, 2024, the Company had outstanding float-to-fixed interest rate swap contracts with an aggregate notional amount of €450 million ($470 million) and maturities of April 2025, April 2026 and April 2028. Changes in the fair value of the undesignated interest rate swap contracts are recorded in Interest expense in the Consolidated Statements of Operations. These interest rate swap contracts were early settled in 2025.

The Company also has outstanding forward currency exchange contracts with maturities generally up to 3 months and an aggregate notional amount of $737 million and $597 million as of December 31, 2025 and 2024, respectively. These derivatives are not designated as hedging instruments and are adjusted to fair value through Non-operating (income) expense in the Consolidated Statements of Operations.

Effect of Derivatives on the Statements of Operations and Statements of Comprehensive Income (Loss)

The following tables present the pretax impact that changes in the fair values of derivatives designated as cash flow hedges and net investment hedges had on OCI, AOCI and earnings:


	Year Ended December 31,
	2025		2024		2023
	(Dollars in millions)
Cash flow hedges
Gain (loss) reclassified from AOCI to income:
Cost of goods sold	$	4	$	3	$	23
Interest expense (1)	7		4		3
Non-operating income (2)	(65)		26		(10)
Gain (loss) recognized in other comprehensive income (loss)	1		(7)		(18)

Net investment hedges
Gain (loss) recognized in other comprehensive income (loss)	(165)		63		(8)

(1) Includes a settlement loss of $3 million for the year ended December 31, 2024.

(2) Includes a settlement loss of $4 million for the year ended December 31, 2024.

The following table summarizes the pretax gain (loss) that changes in the fair values of derivatives not designated as hedging instruments had on earnings:


		Year Ended December 31,
		2025		2024		2023
Contract Type	Location	(Dollars in millions)
Interest rate swaps	Interest expense (1)	$	—	$	9	$	(9)
Forward currency exchange contracts	Non-operating income	24		27		(11)

(1) Includes interest income of $6 million offset by marked-to-market remeasurement losses of $6 million for the year ended December 31, 2025. Includes settlement gain of $22 million and interest income of $24 million partially offset by marked-to-market remeasurement losses of $37 million, for the year ended December 31, 2024. Includes marked-to-market remeasurement losses of $33 million partially offset by interest income of $24 million for the year ended December 31, 2023.

Fair Value Measurement

The foreign currency exchange, interest rate swap and cross-currency swap contracts are valued using market observable inputs. As such, these derivative instruments are classified within Level 2. The assumptions used in measuring fair value of the cross-currency swap contracts are considered Level 2 inputs, which are based upon market observable interest rate curves, cross currency basis curves, credit default swap curves, and foreign exchange rates.

The carrying value of Cash, cash equivalents and restricted cash, Account receivables and Notes and Other receivables contained in the Consolidated Balance Sheets approximates fair value.

The following table sets forth the Company’s financial assets and liabilities that were not carried at fair value:


	December 31, 2025
	Carrying Value		Fair Value
	(Dollars in millions)
Term Loan Facilities	$	626	$	639
2032 Senior Notes	790		850

The Company determined the fair value of its long-term debt and related current maturities utilizing transactions in the listed markets for similar liabilities. As such, the fair value of the Term Loan Facilities and related current maturities is considered Level 2. The fair value of the 2032 Senior Notes was determined using quoted prices from daily exchange traded markets and is classified as a Level 1 measurement.

Stock-Based Compensation

Stock-Based Compensation

Note 21. Stock-Based Compensation

2021 Long-Term Incentive Plan

On May 25, 2021, the Garrett Motion Inc. 2021 Long-Term Incentive Plan (the “Long-Term Incentive Plan”) was adopted. The Long-Term Incentive Plan provides for the grant of stock options, stock appreciation rights, performance awards, restricted stock units, restricted stock, other stock-based awards, and cash-based awards to employees and non-employee directors of Garrett or its affiliates, and independent contractors or consultants of Garrett. The maximum aggregate number of shares of our Common Stock that may be issued under the Long-Term Incentive Plan is 31,280,476 shares. As of December 31, 2025, an aggregate of 11,011,551 shares of our Common Stock were awarded, net of forfeitures and 20,268,925 shares of our Common Stock were available for future issuance under the Long-Term Incentive Plan.

Restricted Stock Units ("RSUs") and Deferred Stock Units ("DSUs")

RSUs are issued to certain key employees and directors at fair market value at the date of grant. RSUs typically vest over 3 to 5 years and when vested, each unit entitles the holder to one share of our Common Stock. In addition, non-employee directors may elect to receive all or part of their annual retainer fees in the form of DSUs which vest upon grant. Each DSU represents the right to receive one share of our Common Stock. DSUs are settled on the earlier of (1) a change in control, or (2) the six months after the director ceases serving on the Board. The following table summarizes information about RSU and DSU activity:


	Number of Restricted and Deferred Stock Units	Weighted Average Grant Date Fair Value Per Share
Non-vested at December 31, 2023	3,035,445	$	7.86
Granted	1,391,412	9.45
Vested	(1,428,791)	7.54
Forfeited	(152,195)	8.46

Non-vested at December 31, 2024	2,845,871	$	8.76
Granted	1,316,459	9.95
Vested	(1,331,324)	8.61
Forfeited	(232,355)	8.91

Non-vested at December 31, 2025	2,598,651	$	9.43

As of December 31, 2025, there was $13 million of total unrecognized compensation cost related to unvested RSUs, which is expected to be recognized over a weighted-average period of 1.70 years.

Performance Stock Units ("PSUs")

As of December 31, 2025, an aggregate of 5,346,162 PSU awards were granted to officers and certain key employees under the Long-Term Incentive Plan, which, upon vesting, entitles the holder to shares of our Common Stock. The actual number of shares an employee receives for each PSU depends on the Company’s performance against various measures.

PSUs are generally earned based on the Company's performance over a three-year period, measured in terms of Adjusted EBITDA and Adjusted EBITDA margin, with some PSUs earned based on achieving certain criteria over new business awards. PSU payouts may range from 0% to 200% of the target award, depending on the level of achievement of these financial and operational metrics.

Additionally, certain PSUs were also granted in 2023, 2024 and 2025 that included a performance measure for relative total shareholder return (“rTSR”) with stock price hurdles measured over a three-year performance period. Each grantee is granted a target level of PSUs and may earn between 0% and 200% of the target level depending on the achievement of the rTSR.

The awards associated with the rTSR performance measures are considered to have a market condition. A Monte-Carlo simulation model was used to determine the grant date fair value by simulating a range of possible future stock prices for the Company over the performance period. This model requires an input of assumptions including the simulation term, the risk-free interest rate, a volatility estimate for the Company’s shares, and a dividend yield estimate. The simulation term was the period of time between performance period start date and the performance end date. The risk-free interest rate assumption was based on observed interest rates from the Treasury Constant Maturity yield curve consistent with the simulation term. The Company’s volatility estimate was based on the historical volatilities of peers over a historical period consistent with the simulation term. The dividend yield in the model is set to zero as recipients of the award are entitled to dividend equivalents on shares that vest. The fair value of the PSUs granted in 2023, 2024 and 2025 were estimated using the following assumptions:


Monte Carlo Assumptions	PSUs Granted in 2025	PSUs Granted in 2024	PSUs Granted in 2023
Volatility	38.02%	41.35%	85.01%
Dividend yield	0.00%	0.00%	0.00%
Risk-free interest rate	3.93%	4.25%	4.26%

The following table summarizes information about PSU activity related to both the Stock Incentive Plan and the Long-Term Incentive Plan for each of the periods presented:


	Number of Performance Stock Units	Weighted Average Grant Date Fair Value Per Share
Non-vested at December 31, 2023	2,828,787	$	8.80
Granted	1,171,883	10.89
Vested	(1,031,104)	8.67
Forfeited	(499,160)	8.61

Non-vested at December 31, 2024	2,470,406	$	9.89
Granted	1,243,166	10.88
Vested	(276,338)	6.79
Forfeited	(199,576)	9.67

Non-vested at December 31, 2025	3,237,658	$	10.49

The fair value of the TSR-based PSUs is based on the output of the Monte Carlo simulation model noted above. The fair values of the PSUs not containing a market condition are based on the fair market value of the Company’s common stock at the grant date. The number of underlying shares to be issued will be based on actual performance achievement over the performance period.

The fair value of each PSU grant is amortized monthly into compensation expense on a graded vesting (accelerated) basis over a vesting period of 36 months. The accrual of compensation costs is based on our estimate of the final expected value of the award and is adjusted as required for the performance-based conditions.

As of December 31, 2025, there was $13 million of total unrecognized compensation cost related to unvested PSUs, which is expected to be recognized over a weighted average period of 1.74 years.

Dividend Equivalents

All RSUs, DSUs and PSUs granted contain rights that entitle the recipient of an award to a dividend equivalent in the amount and form equal to any dividends that would have been paid on the shares of Common Stock underlying the awards had such shares been outstanding on the record dates. Dividend equivalents are accrued on each award from the grant date until the award vests (or the underlying shares are issued in the case of DSUs). The accrual is based on the dividends declared on the Company's Common Stock during the vesting period. The dividend equivalents are not paid out until the underlying award has vested and settled. The dividend equivalents are subject to the same vesting and settlement conditions as the awards. If the award does not vest, the accrued dividend equivalent is forfeited.

Series A Preferred Stock

On April 30, 2021, in connection with emergence from bankruptcy, the Company issued 247,757,290 shares of the Company's Series A Preferred Stock to affiliated funds of Centerbridge, affiliated funds of Oaktree (together with Centerbridge, the "C&O Investors"), and certain other investors and parties.

On the Transaction Date, the Company entered into separate definitive agreements (the “Agreements”) with each of Centerbridge and Oaktree to effect the “Transaction designed to simplify the Company’s capital structure by converting all outstanding shares of Series A Preferred Stock into a single class of Common Stock, subject to certain conditions.

Under the terms of the Agreements, the Company agreed to purchase a total of $570 million in shares of Series A Preferred Stock from the C&O Investors at a cash price per share to be based on the volume-weighted average price of the Common Stock for the fifteen trading days following the announcement of the transactions (the “15 Days VWAP”), subject to a minimum price of $7.875 per share and a maximum price of $8.50 per share. The 15 Days VWAP was subsequently established at a value of $8.177 per share.

Additionally, under the terms of the Agreements, all holders of Series A Preferred Stock, including the C&O Investors, were entitled to receive (i) $0.853509 per share of Series A Preferred Stock, representing accumulated and unpaid preference dividends through June 30, 2023 on each share of Series A Preferred Stock (the “Accumulated Dividends”), which would be paid out in shares of Common Stock valued at the 15 Days VWAP, and (ii) $0.144375 per share of Series A Preferred Stock, representing the preference dividends that would have accrued on the Series A Preferred Stock through September 30, 2023 (the “Additional Amounts”), which would be paid out in cash.

In the second quarter of 2023, the Company completed the following steps in connection with the Transaction:

•The Company issued 25,577,517 shares of Common Stock to holders of the Series A Preferred Stock in respect of the Accumulated Dividends, with immaterial cash payments made in lieu of issuing fractional shares;

•The Company paid approximately $35 million in aggregate to holders of the Series A Preferred Stock in respect of the Additional Amounts, consisting of $10 million to the C&O Investors in consideration of shares to be repurchased and $25 million to all holders in consideration of shares to be converted, which Additional Amounts were considered to be a deemed dividend;

•The Company repurchased 69,707,719 shares of Series A Preferred Stock from the C&O Investors at the 15 Days VWAP for an aggregate purchase price of $570 million; and

•The remaining 175,337,712 shares of Series A Preferred Stock were converted into 175,337,712 shares of Common Stock, and trading of the Series A Preferred Stock on Nasdaq was subsequently suspended.

The Agreements were accounted for as freestanding physically settled forward purchase contracts. The Agreements were initially recorded at fair value and then remeasured through earnings until the establishment of the 15 Days VWAP, whereupon the Agreements were subsequently measured based on the amount of consideration to be paid at settlement. A Monte-Carlo simulation model was used to determine the Transaction Date fair value of the Agreements by simulating a range of possible future stock prices for the Company through the expected settlement date of the Agreements. The significant assumptions utilized in estimating the fair value of the Agreements include: (i) a dividend yield of 0.0%; (ii) an expected volatility of 40.0%; (iii) a risk-free interest rate of 4.23% based on observed interest rates from the Treasury Constant Maturity yield curve consistent with the simulation term; and (iv) a starting share price of $8.25 based on the market price of the Common Stock as of the Transaction Date.

The initial fair value of the Agreements represented a forward purchase liability of $4 million. A loss of $13 million was recognized in Non-operating expense in the Consolidated Statement of Operations to reflect the subsequent remeasurement of fair value of the Agreements due to changes in the market price of the Company’s Common Stock. The difference between the fair value of consideration transferred under the Agreements and the carrying value of the repurchased Series A Preferred Stock, amounting to $201 million, was recorded to Retained Deficit as a deemed dividend on the repurchase of Series A Preferred Stock from the C&O Investors as part of the Transaction. A liability for excise tax, amounting to $6 million, was also recorded to Retained Deficit as a deemed dividend.

The following table summarizes the effects of the Transaction on the Consolidated Financial Statements as of and for the year ended December 31, 2023:


	Series A Repurchase		2023 Conversion		Settlement of Accumulated Dividends		Excise tax on Series A Repurchase		Total

The Company incurred $9 million of Transaction-related costs for the year ended December 31, 2023, primarily for legal and advisory services that are included in Selling, general and administrative expenses in the Consolidated Statement of Operations.

Common Stock

Cash dividends paid to shareholders of our Common Stock for the year ended December 31, 2025 were as follows (in millions, except per share amounts):


	Quarterly Dividends
	2025
	Per Share		Total
First quarter	$	0.06	$	12
Second quarter	0.06		13
Third quarter	0.06		11
Fourth quarter	0.08		16

Dividends payable on shares of Common Stock to be distributed under the Company's Long-Term Incentive Plan will be paid if and when such shares are distributed. See also Note 21, Stock-Based Compensation for further discussion.

Treasury Stock

Treasury stock represents shares of the Company's Common Stock that have been issued and subsequently repurchased by the Company or withheld to satisfy withholding tax obligations in connection with equity award vestings, and that have not been retired or cancelled. The Company accounts for treasury stock under the cost method and includes treasury stock as a component of Equity (Deficit) on the Consolidated Balance Sheet. The Company accounts for the reissuance of treasury stock using the average cost method. The Company did not reissue or retire any shares of treasury stock during the year ended December 31, 2025.

Share Repurchase Program

On December 4, 2024, the Company announced that the Board of Directors had authorized a $250 million share repurchase program valid January 1, 2025 until December 31, 2025. During the year ended December 31, 2025, the Company repurchased 16,890,791 shares of Common Stock for $208 million under the program. These repurchases include a total of 7,500,000 shares of Common Stock for $103 million from funds affiliated with Oaktree Capital Management, L.P., a related party. The repurchased shares are held as treasury stock. The 2025 share repurchase program expired on December 31, 2025.

On December 3, 2025, the Board of Directors authorized a new $250 million share repurchase program valid January 1, 2026 until December 31, 2026. The timing, as well as the number and value of shares repurchased under the program, will depend on a variety of factors. The Company is not obligated to purchase any shares under the repurchase program, and the program may be suspended, modified, or discontinued at any time without prior notice.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

Note 23. Commitments and Contingencies

We are involved in various lawsuits, claims and proceedings incident to the operation of our businesses, including those pertaining to product liability, product safety, environmental, health and safety, intellectual property, employment, commercial and contractual matters and various other matters. We regularly assess the likelihood of adverse judgments or outcomes in these matters, as well as potential ranges of possible losses based on a careful analysis of each matter. We identify below the individual proceedings where we believe a material loss is reasonably possible or probable, and we accrue for matters when we believe that losses are probable and the amount of the potential loss is reasonably estimable. It is inherently difficult to determine whether a loss is probable or reasonably possible or to estimate the size or range of the potential loss. Accordingly, while we believe that appropriate accruals have been established for losses that are probable and can be reasonably estimated, it is possible that adverse outcomes from such proceedings could exceed the amounts accrued by an amount that could be material to our financial position, results of operations or cash flows.

Brazilian Tax Matters

In September 2020, the Brazilian tax authorities issued an infraction notice against Garrett Motion Industria Automotiva Brasil Ltda, challenging the use of certain tax credits (“Befiex Credits”) between January 2017 and February 2020. The infraction notice results in a loss contingency that may or may not ultimately be incurred by the Company. The estimated total amount of the contingency as of December 31, 2025, was $26 million, including penalties and interest. The Company believes, based on management’s assessment and the advice of external legal counsel, that it has meritorious arguments in connection with the infraction notice and any liability for the infraction notice is currently not probable. Accordingly, no accrual has been taken at this time.

Warranties and Guarantees

In the normal course of business, we issue product warranties and product performance guarantees. We accrue for the estimated cost of product warranties and performance guarantees based on contract terms and historical experience at the time of sale to the customer. Adjustments to initial obligations for warranties and guarantees are made as changes to the obligations become reasonably estimable. Product warranties and product performance guarantees are included in Accrued liabilities and Other Liabilities. The following table summarizes information concerning our recorded obligations for product warranties and product performance guarantees.
