Organization, Consolidation and Presentation of Financial Statements [Abstract]
Background and Basis of Presentation	1. BACKGROUND AND BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements of Triumph Group, Inc. ("Triumph") have been prepared in conformity with accounting principles generally accepted in the United States ("U.S. GAAP") for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, the interim financial information includes all adjustments of a normal recurring nature necessary for a fair presentation of the results of operations, financial position, and cash flows. The results of operations for the three and nine months ended December 31, 2023 and 2022, are not necessarily indicative of results that may be expected for the year ending March 31, 2024. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the fiscal 2023 audited consolidated financial statements and notes thereto included in the Company's Form 10-K for the fiscal year ended March 31, 2023, filed with the Securities and Exchange Commission (the "SEC") on May 24, 2023. Triumph Group, Inc. ("Triumph" or the "Company") is a Delaware corporation which, through its operating subsidiaries, designs, engineers, manufactures, and sells products for the global aerospace original equipment manufacturers ("OEMs") of aircraft and aircraft components and repairs and overhauls aircraft components and accessories for commercial airline, air cargo carrier, and military customers on a worldwide basis. Triumph and its subsidiaries (collectively, the "Company") are organized based on the products and services that they provide. The Company has two reportable segments: Systems & Support and Interiors (formerly Aerospace Structures). Systems & Support consists of the Company’s operations that provide integrated solutions, including design; development; and support of proprietary components, subsystems and systems, as well as production of complex assemblies using external designs. Capabilities include hydraulic, mechanical and electromechanical actuation, power, and control; a complete suite of aerospace gearbox solutions, including engine accessory gearboxes and helicopter transmissions; active and passive heat exchange technology; fuel pumps, fuel metering units, and Full Authority Digital Electronic Control fuel systems; and hydromechanical and electromechanical primary and secondary flight controls. As disclosed in Note 3, in December 2023 the Company entered into a definitive agreement with AAR Corp. (“AAR”), to sell Systems & Support's maintenance, repair, and overhaul operations located in Wellington, Kansas; Grand Prairie, Texas; San Antonio, Texas; Hot Springs, Arkansas; and Chonburi, Thailand (“Product Support”). As a result of this agreement, effective in the third quarter of fiscal 2024, the Company has classified the Product Support results of operations for all periods presented as discontinued operations, and has classified the assets and liabilities of the disposal group as held for sale, and these operations are no longer reported as part of the Systems & Support reportable segment. Interiors (formerly Aerospace Structures) consists of the Company’s operations that have historically supplied commercial, business, and regional manufacturers with large metallic structures and continues to supply aircraft interior systems, including air ducting and thermal acoustic insulations systems. Subsequent to the divestitures disclosed in Note 3, the remaining operations of Interiors are those that supply commercial and regional manufacturers with aircraft interior systems. The accompanying condensed consolidated financial statements include the accounts of Triumph and its wholly-owned subsidiaries. Intercompany accounts and transactions have been eliminated from the accompanying condensed consolidated financial statements. The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Revenue Recognition and Contract Balances The Company's revenue is principally from contracts with customers to provide design, development, manufacturing, and support services associated with specific customer programs. The Company regularly enters into long-term master supply agreements that establish general terms and conditions and may define specific program requirements. Many agreements include clauses that provide sole supplier status to the Company for the duration of the program’s life. Purchase orders (or authorizations to proceed) are issued pursuant to the master supply agreements. Additionally, a majority of the Company’s agreements with customers include options for future purchases. Such options primarily reduce the administrative effort of issuing subsequent purchase orders and do not represent material rights granted to customers. The Company generally enters into agreements directly with its customers and is the principal in all current contracts. The identification of a contract with a customer for purposes of accounting and financial reporting requires an evaluation of the terms and conditions of agreements to determine whether presently enforceable rights and obligations exist. Management considers a number of factors when making this evaluation that include, but are not limited to, the nature and substance of the business exchange, the specific contractual terms and conditions, the promised products and services, the termination provisions in the contract, as well as the nature and execution of the customer’s ordering process and how the Company is authorized to perform work. Generally, presently enforceable rights and obligations are not created until a purchase order is issued by a customer for a specified number of units of product or services. Therefore, the issuance of a purchase order is generally the point at which a contract is identified for accounting and financial reporting purposes. Management identifies the promises to the customer. Promises are generally explicitly stated in each contract, but management also evaluates whether any promises are implied based on the terms of the agreement, past business practice, or other facts and circumstances. Each promise is evaluated to determine if it is a performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service. The Company considers a number of factors when determining whether a promise is a distinct performance obligation, including whether the customer can benefit from the good or service on its own or together with other resources that are readily available to the customer, whether the Company provides a significant service of integrating goods or services to deliver a combined output to the customer, or whether the goods or services are highly interdependent. The Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs for OEMs. The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. Typically, the transaction price consists solely of fixed consideration but may include variable consideration for contractual provisions such as unpriced contract modifications, cost-sharing provisions, and other receipts or payments to customers. The Company identifies and estimates variable consideration, typically at the most likely amount the Company expects to receive from its customers. Variable consideration is only included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for the contract will not occur, or when the uncertainty associated with the variable consideration is resolved. Consideration paid or payable to a customer is reflected as a reduction in net revenues when the amounts paid are not related to a distinct good or service at the later of when the related revenue is recognized or when the Company pays or promises to pay the consideration to the customer. The Company's contracts with customers generally require payment under normal commercial terms after delivery with payment typically required within 30 to 120 days of delivery. The Company generally is not subject to collecting sales tax and has made an accounting policy election to exclude from the transaction price any sales and other similar taxes collected from customers. As a result, any such collections are accounted for on a net basis. The total transaction price is allocated to each of the identified performance obligations using the relative stand-alone selling price. The objective of the allocation is to reflect the consideration that the Company expects to receive in exchange for the products or services associated with each performance obligation. Stand-alone selling price is the price at which the Company would sell a promised good or service separately to a customer. Stand-alone selling prices are established at contract inception, and subsequent changes in transaction price are allocated on the same basis as at contract inception. When stand-alone selling prices for the Company’s products and services are not observable, the Company uses either the “Expected Cost Plus a Margin” or "Adjusted Market Assessment" approaches to estimate stand-alone selling price. Expected costs are typically derived from the available periodic forecast information. Revenue is recognized when or as control of promised products or services transfers to a customer and is recognized at the amount allocated to each performance obligation associated with the transferred products or services. Service sales, principally representing repair, maintenance, and engineering activities are recognized over the contractual period or as services are rendered. Sales under long-term contracts with performance obligations satisfied over time are recognized using either an input or output method. The Company recognizes revenue over time as it performs on these contracts because of the continuous transfer of control to the customer as represented by contractual terms that entitle the Company to the reimbursement of costs plus a reasonable profit for work performed to manufacture products for which the Company has no alternate use or for work performed on a customer-owned asset. With control transferring over time, revenue is recognized based on the extent of progress toward completion of the performance obligation. The Company generally uses the cost-to-cost input method of progress for its contracts because it best depicts the transfer of control to the customer that occurs as work progresses. Under the cost-to-cost method, the extent of progress toward completion is measured based on the proportion of costs incurred to date to the total estimated costs at completion of the performance obligation. The Company reviews its cost estimates on contracts on a periodic basis, or when circumstances change and warrant a modification to a previous estimate. Cost estimates are largely based on negotiated or estimated purchase contract terms, historical performance trends, and other economic projections. Significant factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, asset utilization, and anticipated labor agreements. Revenue and cost estimates are regularly monitored and revised based on changes in circumstances. Impacts from changes in estimates of net sales and cost of sales are recognized on a cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a performance obligation’s percentage of completion. Forward loss reserves for anticipated losses on long-term contracts are recorded in full when such losses become evident, to the extent required, and are included in contract liabilities on the accompanying condensed consolidated balance sheets. The Company believes that the accounting estimates and assumptions made by management are appropriate; however, actual results could differ materially from those estimates. For the three and nine months ended December 31, 2023, cumulative catch-up adjustments resulting from changes in estimated contract values and contract costs during the periods were immaterial. For the three months ended December 31, 2022 , cumulative catch-up adjustments resulting from changes in estimates increased net sales, operating income, net income, and earnings per diluted share by approximately $ 1,459 , $ 748 , $ 748 , and $ 0.01 , respectively. For the nine months ended December 31, 2022 , cumulative catch-up adjustments resulting from changes in estimates increased net sales, operating income, net income, and earnings per diluted share by approximately $ 13,360 , $ 20,151 , $ 20,151 , and $ 0.30 , respectively. Revenues for performance obligations that are not recognized over time are recognized at the point in time when control transfers to the customer. For performance obligations that are satisfied at a point in time, the Company evaluates the point in time when the customer can direct the use of and obtain the benefits from the products and services. Generally, the shipping terms determine the point in time when control transfers to customers. Shipping and handling activities are not considered performance obligations and related costs are included in cost of sales as incurred. Differences in the timing of revenue recognition and contractual billing and payment terms result in the recognition of contract assets and liabilities. Refer to Note 4 for further discussion. Concentration of Credit Risk The Company’s trade and other accounts receivable are exposed to credit risk. However, the risk is limited due to the diversity of the customer base and the customer base’s wide geographical area. Trade accounts receivable from The Boeing Company ("Boeing") (representing commercial, military, and space) represented approximately 13 % and 13 % of total trade accounts receivable, including receivables presented within assets held for sale - current, as of December 31, 2023 and March 31, 2023 , respectively. As of March 31, 2023, trade and other receivables from Daher Aerospace Inc. ("Daher") include receivables that largely corresponded with payables associated with transition services and represented approximately 20 % as of March 31, 2023. The transition services agreement with Daher contractually expired as of June 30, 2023, and remaining receivables and payables as of that date were not significant. The Company had no other concentrations of credit risk of more than 10%. Sales to Boeing from continuing operations for the nine months ended December 31, 2023, were $ 200,577 , or 24 % of net sales, of which $ 123,323 and $ 77,254 were from Systems & Support and Interiors, respectively. Sales to Boeing for the nine months ended December 31, 2023, included within discontinued operations were approximately $ 31,366 . Sales to Boeing from continuing operations for the nine months ended December 31, 2022, were $ 238,750 , or 30 % of net sales, of which $ 110,290 and $ 128,460 were from Systems & Support and Interiors, respectively. Sales to Boeing for the nine months ended December 31, 2022, included within discontinued operations were approximately $ 27,066 . No other single customer accounted for more than 10% of the Company’s net sales. However, the loss of any significant customer, including Boeing, could have a material adverse effect on the Company and its operating subsidiaries. Warrants On December 1, 2022, the Company’s board of directors declared a distribution to holders of the Company’s shares of common stock in the form of warrants to purchase shares of common stock (the “Warrants”). Holders of common stock received three Warrants for every ten shares of common stock held as of December 12, 2022 (the "Record Date"). The Company issued approximately 19.5 million Warrants on December 19, 2022, to holders of record of common stock as of the close of business on the Record Date. Each Warrant represented the right to purchase initially one share of common stock, at an exercise price of $ 12.35 per Warrant, subject to certain anti-dilution adjustments. Payment for shares of common stock on exercise of Warrants could have been made in (i) cash or (ii) under certain circumstances, certain of the Company's outstanding notes (the "Designated Notes"). The common stock warrants are accounted for as derivative liabilities in accordance with ASC 815-40 and included within accrued liabilities on the accompanying condensed consolidated balance sheets. The Company measured the Warrants at fair value as of the issuance date using a Monte Carlo pricing model, a Level 3 fair value measurement (as described below), due to the level of market activity. Inherent in the option pricing simulation are assumptions related to expected stock-price volatility, expected life and risk-free interest rate. The Company estimates the volatility of the Warrants based on implied and historical volatility of the Company’s common stock. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the Warrants. The expected life of the Warrants is based on the Company’s ability to redeem the Warrants, subject to a 20 calendar-day notice period, as well as the automatic acceleration of the Expiration Date following the Price Condition Date. During the three months ended December 31, 2022, due to increased trading volume, the Company began remeasuring outstanding Warrants using the Warrants trading price, a Level 1 fair value measurement (as described below). The Warrants are remeasured at each balance sheet date. Warrants remeasurement adjustments are recognized in warrant remeasurement gain, net on the accompanying condensed consolidated statements of operations. At distribution, the fair value of the Warrants was $ 19,500 . Approximately 7.7 million of Warrants were exercised in the six months ended September 30, 2023, resulting in total cash proceeds, net of transaction costs, of approximately $ 79,961 , and $ 8,532 of warrants remeasurement gain was recognized in the six months ended September 30, 2023. On July 6, 2023 , the Company redeemed all of the approximately 11.4 million remaining outstanding Warrants for a total redemption price of approximately $ 11 pursuant to its June 16, 2023, notice of redemption. Contingencies Contingences are existing conditions, situations or circumstances involving uncertainty as to possible gain or loss that will ultimately be resolved when future events occur or fail to occur. Such contingencies include, but are not limited to environmental obligations, litigation, regulatory investigations and proceedings, product quality, and gains or losses resulting from other events and developments. Liabilities for loss contingencies are accrued in the amount of the Company's best estimate for the ultimate loss when a loss is considered probable of having been incurred and is reasonably estimable. When there appears to be a range of possible costs with equal likelihood, liabilities are based on the low-end of such range. Disclosure is provided for material loss contingencies when a loss is probable but a reasonable estimate cannot be made, and when it is reasonably possible that a loss will be incurred or the amount of a loss will exceed the recorded provision. The Company regularly reviews contingencies to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the loss or range of loss can be made. Contingencies that might result in gains are generally not accrued until the contingencies are resolved and the gain is realized or realizable. Refer to Note 12 for further disclosure. Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements when measuring the warrants (refer to the above disclosure), when disclosing the fair value of its long-term debt not recorded at fair value (see Note 6), and to its pension and postretirement plan assets (see Note 9). Supplemental Cash Flow Information For the nine months ended December 31, 2023 and 2022 the Company paid $ 4,962 and $ 3,838 , respectively f or income taxes, net of income tax refunds received.

Divested Operations and Assets Held For Sale	3. DIVESTED OPERATIONS AND ASSETS HELD FOR SALE Fiscal 2024 Divestiture and Discontinued Operations In December 2023, the Company’s Board of Directors committed to a plan, and the Company entered into a definitive agreement with AAR, to sell Product Support for cash proceeds of $ 725,000 subject to adjustments related to the closing balance sheet and certain transaction expenses; the adjustments will be estimated at closing and are expected to be finalized during the first half of fiscal 2025. Product Support companies provide aftermarket maintenance, repair, and overhaul solutions for commercial, regional and military aircraft. The transaction is expected to close during the fourth quarter of fiscal 2024 and result in a significant gain. As a result of this planned transaction, effective in the third quarter of fiscal 2024, we have classified our results of operations for all periods presented to reflect Product Support as discontinued operations and classified the assets and liabilities of this disposal group as held for sale. Under the terms of the purchase agreement, we will continue to guarantee the performance of certain of the divested legal entities pursuant to pre-existing performance guarantee agreements covering existing contracts with specific customers that are expected to be fully satisfied within the next twelve months. There is no limitation to the maximum potential future liabilities under these guarantee agreements; however, we are fully indemnified by the buyer, AAR, against such losses that may arise from their failure to perform under the related contracts. Other than these guarantees, a short-term transition services agreement, commercial purchases and sales which are not significant and are entered into in the ordinary course of business, and other customary short-term transitional activities, the Company will have no further continuing involvement with Product Support. On February 6, 2024, the Company provided holders of the 2028 First Lien Notes with a conditional notice of redemption to redeem approximately $ 120,000 of the 2028 First Lien Notes (as defined in Note 6 below) at a redemption price equal to 103 % of the aggregate principal amount plus accrued and unpaid interest . The Company also provided holders of the 2025 Notes (as defined in Note 6 below) with a conditional notice of redemption to redeem up to all of the outstanding 2025 Notes at 100 % of the aggregate principal amount plus accrued and unpaid interest. Both redemptions are conditioned on the closing of the sale of Product Support, and the unsecured redemption will only occur after the Company conducts an asset sale offer whereby it will first offer the proceeds allocated to redeem the 2025 Notes to repurchase the 2028 First Lien Notes at 100 % of the aggregate principal amount plus accrued and unpaid interest. In the event that the Company redeems more than $ 140,000 of the 2028 First Lien Notes pursuant to the asset sale offer, the redemption of the 2025 Notes will be reduced dollar-for-dollar by the amount of the 2028 First Lien Notes that are redeemed above $ 140,000 . If the Company redeems more than $ 575,621 of 2028 First Lien Notes pursuant to the asset sale offer, the redemption of the 2025 Notes will not occur. As a result of this planned transaction, effective in the third quarter of fiscal 2024, we have classified our results of operations for all periods presented to reflect Product Support as discontinued operations and classified the assets and liabilities of this disposal group as held for sale. The following table shows the results of Product Support within discontinued operations for each of the periods presented: Three Months Ended December 31, Nine Months Ended December 31, 2023 2022 2023 2022 Major line items constituting pretax (loss) income of discontinued operations Net sales $ 64,855 $ 67,194 $ 197,560 $ 180,735 Operating costs and expenses: Cost of sales (exclusive of depreciation shown separately below) 49,703 50,188 148,058 132,653 Selling, general and administrative 8,749 4,772 19,247 14,414 Depreciation and amortization 2,144 826 3,625 2,642 Restructuring — — — 1,777 60,596 55,786 170,930 151,485 Operating income 4,259 11,408 26,630 29,250 Interest expense and other, net 6,004 5,592 18,602 17,464 (Loss) income from discontinued operations before income taxes ( 1,745 ) 5,816 8,028 11,786 Income tax expense 2,246 376 3,459 1,232 (Loss) income from discontinued operations $ ( 3,991 ) $ 5,440 $ 4,569 $ 10,554 The Company's accounting policy to allocate to discontinued operations other consolidated interest that is not directly attributable to or related to other operations of the entity based on the ratio of net assets to be sold or discontinued less debt that is required to be paid as a result of the disposal transaction to the sum of total net assets of the consolidated group plus consolidated debt, adjusted for debt that will be assumed by the buyer; debt that is required to be paid as a result of the disposal transaction; and debt that can be directly attributed to other operations of the entity. In applying the above policy, the Company allocated interest expense to discontinued operations of approximately $ 5,945 and $ 5,215 in the three months ended December 31, 2023 and 2022, respectively, and $ 16,428 and $ 17,932 in the nine months ended December 31, 2023 and 2022, respectively. The following table shows the major classes of assets and liabilities held for sale: December 31, March 31, 2023 2023 ASSETS Carrying amount of major classes of assets included as part of discontinued operations: Trade and other receivables, less allowance for credit losses 3,011 and $ 2,905 $ 43,080 $ 40,659 Contract assets 17,647 16,287 Inventory, net 87,129 80,161 Prepaid expenses and other current assets 2,087 2,989 Property and equipment, net 26,161 28,178 Other, net 4,538 2,488 Total assets of the disposal group classified as held-for-sale in the statement of financial position $ 180,642 $ 170,762 LIABILITIES Carrying amount of major classes of liabilities included as part of discontinued operations: Accounts payable $ 21,788 $ 24,357 Contract liabilities 104 387 Accrued expenses 9,726 9,669 Other noncurrent liabilities 598 65 Total liabilities of the disposal group classified as held-for-sale in the statement of financial position $ 32,216 $ 34,478 The accompanying condensed consolidated statements of cash flows do not present cash flows from discontinued operations separately from cash flows from continuing operations. Cash provided by operating activities related to discontinued operations totaled $ 18,610 and $ 14,586 for the nine months ended December 31, 2023 and 2022, respectively. Cash used in investing activities related to discontinued operations totaled $( 3,023 ) and $( 2,660 ) for the nine months ended December 31, 2023 and 2022, respectively. Cash used in financing activities was immaterial. Fiscal 2023 Divestitures In January 2022, the Company’s Board of Directors committed to a plan to sell its manufacturing operations located in Stuart, Florida. In February 2022, the Company entered into a definitive agreement with the buyer of these manufacturing operations. This transaction closed in July 2022. The Company recognized a gain of approximately $ 96,800 , net of transaction costs in fiscal year 2023. In the nine months ended December 31, 2023 , the Company paid $ 6,800 to the buyer of the Stuart manufacturing operations and recognized a loss of approximately $ 3,900 due to the resolution of claims by the buyer related to the accounts payable representation and warranty under the purchase agreement and the finalization of certain purchase price adjustments related to the transferred working capital of the divested operations. Additionally, in the nine months ended December 31, 2023 , the Company recognized a loss on sale of approximately $ 8,300 related to an adjustment that would have reduced the fiscal 2023 gain on sale. Other claims for indemnification with the Buyer of the Stuart facility (refer to Note 12) remain outstanding. The operating results of the Stuart, Florida, manufacturing operations are included within the Interiors reportable segment through the date of divestiture.

Revenue Recognition and Contracts with Customers	4. REVENUE RECOGNITION AND CONTRACTS WITH CUSTOMERS Disaggregation of Revenue The Company disaggregates revenue based on the method of measuring satisfaction of the performance obligation either over time or at a point in time. Additionally, the Company disaggregates revenue based upon the end market where products and services are transferred to the customer. The Company’s principal operating segments and related revenue are discussed in Note 11. The following table shows disaggregated net sales satisfied overtime and at a point in time (excluding intercompany sales) for the three and nine months ended December 31, 2023 and 2022: Three Months Ended Nine Months Ended 2023 2022 2023 2022 Systems & Support Satisfied over time $ 73,289 $ 77,559 $ 230,959 $ 222,109 Satisfied at a point in time 166,786 140,077 484,590 409,436 Revenue from contracts with customers 240,075 217,636 715,549 631,545 Amortization of acquired contract liabilities 800 442 1,965 1,832 Total Systems & Support revenue 240,875 218,078 717,514 633,377 Interiors Satisfied over time $ 37,067 $ 37,692 $ 97,712 $ 155,740 Satisfied at a point in time 7,013 5,892 18,230 15,987 Revenue from contracts with customers 44,080 43,584 115,942 171,727 Total Interiors revenue 44,080 43,584 115,942 171,727 Total revenue $ 284,955 $ 261,662 $ 833,456 $ 805,104 The following table shows disaggregated net sales by end market (excluding intercompany sales) for the three and nine months ended December 31, 2023 and 2022: Three Months Ended Nine Months Ended 2023 2022 2023 2022 Systems & Support OEM Commercial $ 98,178 $ 76,975 $ 275,805 233,319 OEM Military 61,149 61,705 190,758 180,901 MRO Commercial 35,089 30,485 106,938 84,910 MRO Military 38,328 39,093 117,835 111,729 Non-aviation 7,331 9,378 24,213 20,686 Revenue from contracts with customers 240,075 217,636 715,549 631,545 Amortization of acquired contract liabilities 800 442 1,965 1,832 Total Systems & Support revenue $ 240,875 $ 218,078 $ 717,514 633,377 Interiors OEM Commercial $ 44,078 $ 42,992 $ 114,819 163,877 MRO Commercial — 437 704 2,808 Non-aviation 2 155 419 5,042 Revenue from contracts with customers 44,080 43,584 115,942 171,727 Total Interiors revenue 44,080 43,584 115,942 171,727 Total revenue $ 284,955 $ 261,662 $ 833,456 805,104 Contract Assets and Liabilities Contract assets primarily represent revenues recognized for performance obligations that have been satisfied or partially satisfied but for which amounts have not been billed. This typically occurs when revenue is recognized over time but the Company's contractual right to bill the customer and receive payment is conditional upon the satisfaction of additional performance obligations in the contract, such as final delivery of the product. Contract assets are typically derecognized when billed in accordance with the terms of the contract. The Company pools contract assets that share underlying risk characteristics and records an allowance for expected credit losses based on a combination of prior experience, current economic conditions and management’s expectations of future economic conditions, and specific collectibility matters when they arise. Contract assets are presented net of this reserve on the condensed consolidated balance sheets. For the three and nine months ended December 31, 2023 and 2022, credit loss expense and write-offs related to contract assets were immaterial. Contract liabilities are recorded when customers remit contractual cash payments in advance of the Company satisfying performance obligations under contractual arrangements, including those with performance obligations to be satisfied over a period of time. Contract liabilities other than those pertaining to forward loss reserves are derecognized when or as revenue is recognized. Contract modifications can also impact contract asset and liability balances. When contracts are modified to account for changes in contract specifications and requirements, the Company considers whether the modification either creates new or changes the existing enforceable rights and obligations. Contract modifications that are for goods or services that are not distinct from the existing contract, due to the significant integration with the original good or service provided, are accounted for as if they were part of that existing contract. The effect of a contract modification to an existing contract on the transaction price and the Company's measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct and at relative stand-alone selling price, they are accounted for as a new contract and performance obligation and are recognized prospectively. Contract balances are classified as assets or liabilities on a contract-by-contract basis at the end of each reporting period. The following table summarizes the Company's contract assets and liabilities balances: December 31, 2023 March 31, 2023 Change Contract assets $ 89,406 $ 86,740 $ 2,666 Contract liabilities ( 40,182 ) ( 44,558 ) 4,376 Net contract asset $ 49,224 $ 42,182 $ 7,042 The change in contract assets is the result of revenue recognized in excess of amounts billed during the nine months ended December 31, 2023. The change in contract liabilities is the result of revenue recognized in excess of receipt of additional customer advances during the nine months ended December 31, 2023. For the nine months ended December 31, 2023, the Company recognized $ 18,359 of revenue that was included in the contract liability balance at the beginning of the period. Performance Obligations Customers generally contract with the Company for requirements in a segment relating to a specific program, and the Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs. A single contract may contain multiple performance obligations consisting of both recurring and nonrecurring elements. As of December 31, 2023, the Company has the following unsatisfied, or partially unsatisfied, performance obligations that are expected to be recognized in the future as noted in the table below. The Company expects options to be exercised in addition to the amounts presented below. Total Less than 1 year 1 - 3 years 4 - 5 years More than 5 Unsatisfied performance obligations $ 1,594,870 $ 979,462 $ 604,881 $ 10,527 $ —

Long-Term Debt	6. LONG-TERM DEBT Long-term debt consists of the following: December 31, March 31, 2023 2023 Finance leases $ 14,809 $ 14,816 Senior secured first lien notes due 2028 1,200,000 1,200,000 Senior notes due 2025 435,621 499,024 Other notes 1,939 — Less: debt issuance costs ( 21,217 ) ( 22,058 ) 1,631,152 1,691,782 Less: current portion 3,342 3,162 $ 1,627,810 $ 1,688,620 Receivables Securitization Program In connection with the Company's receivables securitization facility (the "Securitization Facility"), the Company sells on a revolving basis certain eligible accounts receivable to Triumph Receivables, LLC, a wholly-owned special-purpose entity, which in turn sells a percentage ownership interest in the receivables to commercial paper conduits sponsored by financial institutions. The Company is the servicer of the trade accounts receivable under the Securitization Facility. Interest rates are based on the Bloomberg Short Term Bank Yield Index ("BSBY"), plus a 2.25 % fee on the drawn portion and a fee ranging from 0.45 % to 0.50 % on the undrawn portion of the Securitization Facility. The drawn fee may be reduced to 2.00 % depending on the credit rating of the Company. Collateralized letters of credit incur fees at a rate of 0.125 %. The Company secures its trade accounts receivable, which are generally non-interest-bearing, in transactions that are accounted for as borrowings pursuant to ASC 860, Transfers and Servicing . The Company has established a letter of credit facility under the Securitization Facility. Under the provisions of the letter of credit facility, the Company may request the Securitization Facility’s administrator to issue one or more letters of credit that will expire no later than 12 months after the date of issuance, extension or renewal, as applicable. In December 2023, the Company amended the Securitization Facility, decreasing the purchase limit from $ 100,000 to $ 75,000 , modifying certain other terms, and extending the term through December 2025. As of December 31, 2023 , the maximum amount available under the Securitization Facility was $ 75,000 . The actual amount available under the Securitization Facility at any point in time is dependent upon the balance of eligible accounts receivable as well as the amount of letters of credit outstanding. At December 31, 2023, there were $ 0 in borrowings and $ 19,623 in letters of credit outstanding under the Securitization Agreement, primarily to support insurance policies. The agreements governing the Securitization Facility contain restrictions and covenants, including limitations on the making of certain restricted payments; creation of certain liens; and certain corporate acts such as mergers, consolidations and the sale of all or substantially all the Company's assets. Senior Secured First Lien Notes due 2028 On March 14, 2023, the Company issued $ 1,200,000 principal amount of 9.000 % Senior Secured First Lien Notes due March 15, 2028, pursuant to an indenture among the Company, the Guarantor Subsidiaries, and U.S. Bank National Association, as trustee (the “2028 First Lien Notes”). The 2028 First Lien Notes were sold at 100 % of the principal amount and have an effective interest yield of 9.000 %. Interest is payable semiannually in cash in arrears on March 15 and September 15 of each year , commencing on September 15, 2023. In the nine months ended December 31, 2023 , the Company recognized a gain of approximately $ 3,400 related to an adjustment to its deferred debt issuance costs, a portion of which related to fiscal 2023. The total issuance costs incurred i n connection with the issuance of the 2028 First Lien Notes are now approximately $ 23,000 and are being amortized over the term of the 2028 First Lien Notes. The 2028 First Lien Notes and the guarantees are first lien secured obligations of the Company and the Guarantor Subsidiaries. The 2028 First Lien Notes: (i) rank equally in right of payment to any existing and future senior indebtedness of the Company and Guarantor Subsidiaries, including the 2025 Notes (as defined below); (ii) are effectively senior to all existing and future second lien obligations and all existing and future unsecured indebtedness of the Company and the Guarantor Subsidiaries (including the 2025 Notes), but only to the extent of the value of the Collateral (as defined below), and after giving effect to any permitted additional first lien secured obligations and other permitted liens of senior or equal priority); (iii) are senior in right of payment to all future subordinated indebtedness of the Company and the Guarantor Subsidiaries; (iv) are secured by the Collateral on a pari passu basis with any future permitted additional first lien secured obligations, subject to the Collateral Trust Agreement; (v) are effectively subordinated to any existing and future obligations of the Company and the Guarantor Subsidiaries that are secured by assets that do not constitute the Collateral, in each case, to the extent of the value of the assets securing such obligations; and (vi) are structurally subordinated to all existing and future indebtedness and other liabilities of the Company’s existing and future subsidiaries that do not guarantee the 2028 First Lien Notes, including the Securitization Facility. The 2028 First Lien Notes are guaranteed on a full, senior, joint and several basis by each of the Company’s domestic restricted subsidiaries (the “Guarantor Subsidiaries”) that guarantees the 2025 Notes. In the future, each of the Company’s domestic restricted subsidiaries (other than any domestic restricted subsidiary that is a receivable subsidiary) that (1) is not an immaterial subsidiary, (2) becomes a borrower under any of its material debt facilities or (3) guarantees (a) any of the Company’s indebtedness or (b) any indebtedness of the Company’s domestic restricted subsidiaries, in the case of either (a) or (b), incurred under any of the Company’s material debt facilities, will guarantee the 2028 First Lien Notes. Under certain circumstances, the guarantees may be released without action by, or consent of, the holders of the 2028 First Lien Notes. The 2028 First Lien Notes and the guarantees are secured, subject to permitted liens, by first-priority liens on substantially all of the Company’s and the Guarantor Subsidiaries’ assets (including certain of the Company’s real estate assets), whether now owned or hereafter acquired, other than certain excluded property, which liens will secure permitted additional first lien obligations on a pari passu basis, subject to the Collateral Trust Agreement (the “Collateral”). Under certain circumstances, the Collateral may be released without action by, or the consent of, the holders of the 2028 First Lien Notes. The 2028 First Lien Notes and the guarantees will not be secured by the assets of Non-Guarantor Subsidiaries (as defined below), which include the unrestricted subsidiaries to whom certain of the Company’s accounts receivables are and may in the future be sold to support borrowing under the Receivables Securitization Facility. A collateral trust agreement (the “Collateral Trust Agreement”) among the Company, the Guarantor Subsidiaries, the Collateral Trustee and U.S. Bank National Association, in its capacity as the trustee for the 2028 First Lien Notes, sets forth therein the relative rights with respect to the Collateral as among the trustee for the 2028 First Lien Notes and certain subsequent holders of first lien obligations and covering certain other matters relating to the administration of security interests. The Collateral Trust Agreement generally controls substantially all matters related to the Collateral, including with respect to decisions, distribution of proceeds or enforcement. Pursuant to the Collateral Trust Agreement, on the issue date of the 2028 First Lien Notes the Collateral Trustee will control certain matters related to the Collateral that the Collateral Trust Agreement specifies are in its discretion. If the Company incurs certain types of additional first lien obligations, the Controlling First Lien Holders (as defined in the Collateral Trust Agreement) will have the right to control decisions relating to the Collateral that are outside the Collateral Trustee’s discretion under the Collateral Trust Agreement and the 2028 Note holders may no longer be in control of such decisions. The Company may redeem the 2028 First Lien Notes, in whole or in part, at any time or from time to time on or after March 15, 2025, at specified redemption prices, plus accrued and unpaid interest, if any, to the redemption date. At any time or from time to time prior to March 15, 2025, the Company may redeem the 2028 First Lien Notes, in whole or in part, at a redemption price equal to 100 % of their principal amount plus a make whole premium, together with accrued and unpaid interest, if any, to the redemption date. In addition, the Company may redeem up to 40 % of the aggregate principal amount of the outstanding 2028 First Lien Notes prior to March 15, 2025, with the net cash proceeds from certain equity offerings at a redemption price equal to 109.000 % of their principal amount, together with accrued and unpaid interest, if any, to the redemption date. The Company may redeem, at any time from time to time before March 15, 2025, up to 10 % of the aggregate principal amount of the notes per annum, at a redemption price equal to 103 % of the aggregate principal amount plus accrued and unpaid interest, if any, to the redemption date. If the Company experiences specific kinds of changes of control, the Company is required to offer to purchase all of the 2028 First Lien Notes at a purchase price of 101 % of their principal amount, plus accrued and unpaid interest, if any, to the date of purchase. The 2028 First Lien Notes Indenture contains covenants that, among other things, limit the ability of the Company and its restricted subsidiaries to: (i) incur additional indebtedness; (ii) pay dividends or make other distributions; (iii) make other restricted payments and investments; (iv) create liens; (v) incur restrictions on the ability of restricted subsidiaries to pay dividends or make certain other payments; (vi) sell assets, including capital stock of restricted subsidiaries; (vii) enter into sale and leaseback transactions; (viii) merge or consolidate with other entities; and (ix) enter into transactions with affiliates. In addition, the 2028 First Lien Notes Indenture requires, among other things, the Company to provide financial and current reports to holders of the 2028 First Lien Notes or file such reports electronically with the SEC. These covenants are subject to a number of exceptions, limitations and qualifications set forth in the Indenture, as well as suspension periods in certain circumstances. Senior Notes Due 2025 On August 17, 2017, the Company issued $ 500,000 principal amount of 7.750 % Senior Notes due August 15, 2025 (the "2025 Notes", and, together with the 2028 First Lien Notes, the “Senior Notes”). The 2025 Notes were sold at 100 % of the principal amount and have an effective interest yield of 7.750 %. Interest is payable semiannually in cash in arrears on February 15 and August 15 of each year, commencing on February 15, 2018. In connection with the issuance of the 2025 Notes, the Company incurred approximately $ 8,779 of costs, which were deferred and are being amortized on the effective interest method over the term of the 2025 Notes. The 2025 Notes are the Company's senior unsecured obligations and rank equally in right of payment with all of its other existing and future senior unsecured indebtedness and senior in right of payment to all of its existing and future subordinated indebtedness. The 2025 Notes are guaranteed on a full, joint and several basis by each of the Guarantor Subsidiaries. The Company may redeem some or all of the 2025 Notes at 100 % of their principal amount, plus accrued and unpaid interest, if any, to the redemption date. The Company is obligated to offer to repurchase the 2025 Notes at a price of (i) 101 % of their principal amount plus accrued and unpaid interest, if any, as a result of certain change-of-control events and (ii) 100 % of their principal amount plus accrued and unpaid interest, if any, in the event of certain asset sales. These restrictions and prohibitions are subject to certain qualifications and exceptions. The indenture governing the 2025 Notes (the "2025 Indenture") contains covenants that, among other things, limit the Company's ability and the ability of any of the guarantor subsidiaries to (i) grant liens on its assets, (ii) make dividend payments, other distributions or other restricted payments, (iii) incur restrictions on the ability of the Guarantor Subsidiaries to pay dividends or make other payments, (iv) enter into sale and leaseback transactions, (v) merge, consolidate, transfer or dispose of substantially all of their assets, (vi) incur additional indebtedness, (vii) use the proceeds from sales of assets, including capital stock of restricted subsidiaries, and (viii) enter into certain transactions with affiliates. In the nine months ended December 31, 2023, approximately $ 13,404 in principal amount of the 2025 Notes were used to pay the exercise price for approximately 0.9 million Warrants. In August, the Company executed a 10b5-1 repurchase plan agreement with a third-party (the "Agent") granting the Agent the authority to repurchase on the open market up to $ 50,000 in principal amount of the 2025 Notes, subject to specific conditions, including daily volume and market prices. Pursuant to this agreement, i n the nine months ended December 31, 2023 , the Company used approximately $ 48,062 to redeem $ 50,000 principal amount of the 2025 Notes. The extinguishment gains on these transactions totaled approximately $ 1,700 . Financial Instruments Not Recorded at Fair Value Carrying amounts and the related estimated fair values of the Company's long-term debt not recorded at fair value in the consolidated financial statements are as follows: December 31, 2023 March 31, 2023 Carrying Fair Carrying Fair $ 1,631,152 $ 1,728,754 $ 1,691,782 $ 1,676,879 The fair value of the long-term debt was calculated based on either interest rates available for debt with terms and maturities similar to the Company's existing debt arrangements or broker quotes on the Company's existing debt (Level 2 inputs). Interest paid on indebtedness during the nine months ended December 31, 2023 and 2022, amounted to $ 75,108 and $ 89,225 , respectively.

Earnings per Share

Earnings Per Share [Abstract]
Earnings per Share	7. EARNINGS PER SHARE The calculation of basic earnings per share is based on (loss) income from continuing operations, (loss) income from discontinued operations, or net (loss) income divided by the weighted average number of common shares considered outstanding during the periods. The calculation of diluted earnings per share reflects the effect of all potentially dilutive securities (principally outstanding warrants and outstanding restricted stock units) and is based on (loss) income from continuing operations, (loss) income from discontinued operations, or net (loss) income divided by the diluted weighted average number of common shares considered outstanding during the periods. As disclosed in Note 2, the Warrants permitted the tendering of Designated Notes in payment of the exercise price. In computing diluted earnings per share, the Company applies the if-converted method to the warrants and such warrants are assumed to be exercised and the Designated Notes are assumed to be tendered unless tendering cash would be more advantageous to the warrant holder. Interest (net of tax) on any Designated Notes assumed to be tendered is added back as an adjustment to the (loss) income from continuing operations numerator as the warrants are transactions related to continuing operations. The (loss) income from continuing operations numerator is also adjusted for any nondiscretionary adjustments based on income (net of tax) including, for example, warrant remeasurement gains and losses recognized in the period. If cash exercise is more advantageous, the Company applies the treasury stock method to the warrants when calculating diluted earnings per share. The following is a reconciliation between the weighted average outstanding shares used in the calculation of basic and diluted earnings per share: Three Months Ended December 31, Nine Months Ended December 31, (in thousands) 2023 2022 2023 2022 Numerator: Numerator for basic earnings per share: (Loss) income from continuing operations $( 11,911 ) $ 5,512 $( 39,930 ) $ 96,582 Effect of Dilutive Securities: Warrants — ( 5,730 ) — ( 5,730 ) Numerators for diluted earnings per share: (Loss) income from continuing operations available to common stockholders after assumed conversions $( 11,911 ) $( 218 ) $( 39,930 ) $ 90,852 (Loss) income from discontinued operations, net of tax ( 3,991 ) 5,440 4,569 10,554 Net (loss) income available to common stockholders after assumed conversions $( 15,902 ) $ 5,222 $( 35,361 ) $ 101,406 Denominator: Denominator for basic earnings per share Weighted average common shares outstanding - basic 76,895 65,066 73,200 64,969 Effect of Dilutive Securities: Warrants — 3,169 — 1,056 Restricted stock units — 219 — 321 Dilutive potential common shares — 3,388 — 1,377 Denominator for basic earnings per share Weighted average common shares outstanding - diluted 76,895 68,454 73,200 66,346 Earnings (loss) per share: Basic (loss) earnings per share - continuing operations $( 0.15 ) $ 0.09 $( 0.55 ) $ 1.49 Basic (loss) earnings per share - discontinued operations ( 0.05 ) 0.08 0.06 0.16 Basic (loss) earnings per share $( 0.20 ) $ 0.17 $( 0.49 ) $ 1.65 Diluted (loss) earnings per share - continuing operations $( 0.15 ) $- $( 0.55 ) $ 1.37 Diluted (loss) earnings per share - discontinued operations ( 0.05 ) 0.08 0.06 0.16 Diluted (loss) earnings per share $( 0.20 ) $ 0.08 $( 0.49 ) $ 1.53 (1) For the three and nine months ended December 31, 2023 , no shares and approximately 6.2 million shares, respectively, that could potentially dilute earnings per share as a result of warrants outstanding during the respective periods were not included in diluted weighted average common shares outstanding because to do so would be anti-dilutive. For the three and nine months ended December 31, 2023 and 2022 , the shares that could potentially dilute earnings per share in the future related to stock options and non-vested share-based compensation that were not included in diluted weighted average common shares outstanding because to do so would have been anti-dilutive were immaterial.

Income Taxes

Income Taxes	9 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	8. INCOME TAXES The Company follows the Income Taxe s topic of ASC 740, which prescribes a recognition threshold and measurement attribute criteria for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return, as well as guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The Company's policy is to release the tax effects from accumulated other comprehensive income when all of the related assets or liabilities that gave rise to the accumulated other comprehensive income have been derecognized. The Company has classified uncertain tax positions as noncurrent income tax liabilities unless expected to be paid in one year. Penalties and tax-related interest expense are reported as a component of income tax expense and are not significant. As of December 31, 2023 and March 31, 2023, the total amount of unrecognized tax benefits was $ 12,340 and $ 12,085 , respectively, most of which would impact the effective rate, if recognized. The Company does not anticipate that total unrecognized tax benefits will be reduced in the next 12 months. As of December 31, 2023, the Company has a valuation allowance against principally all of its net deferred tax assets given insufficient positive evidence to support the realization of the Company’s deferred tax assets. The Company intends to continue maintaining a valuation allowance on its deferred tax assets until there is sufficient positive evidence to support the reversal of all or some portion of this allowance. A reduction in the valuation allowance could result in a significant decrease in income tax expense in the period that the release is recorded. However, the exact timing and amount of the reduction in its valuation allowance is unknown at this time and will be subject to the earnings level the Company achieves during fiscal 2024 and future periods. The effective income tax rate for the three months ended December 31, 2023, was ( 9.9 )% as compared with 0.4 % for the three months ended December 31, 2022. The effective income tax rate for the nine months ended December 31, 2023 was ( 9.2 %) as compared with 2.7 % for the nine months ended December 31, 2022. For the three and nine months ended December 31, 2023, the effective tax rate in all periods reflected a limitation on the recognition of tax benefits due to the full valuation allowance and tax expense primarily related to foreign operations. With few exceptions, the Company is no longer subject to U.S. federal, state, or local income tax examinations for fiscal years ended before March 31, 2014, or foreign income tax examinations by tax authorities for fiscal years ended before March 31, 2013. The Company believes appropriate provisions for all outstanding issues have been made for all jurisdictions and all open years.

Pension and Other Postretiremen

Pension and Other Postretirement Benefit Plans	9 Months Ended

Retirement Benefits [Abstract]
Pension and Other Postretirement Benefit Plans	9. PENSION AND OTHER POSTRETIREMENT BENEFIT PLANS The Company sponsors several defined benefit pension plans covering some of its employees. Most employees are ineligible to participate in the plans or have ceased to accrue additional benefits under the plans based upon their service to the Company or years of service accrued under the defined benefit pension plans. Benefits under the defined benefit plans are based on years of service and, for most non-represented employees, on average compensation for certain years. It is the Company’s policy to fund at least the minimum amount required for all qualified plans, using actuarial cost methods and assumptions acceptable under U.S. Government regulations (and for non-U.S. plans, acceptable under local regulations), by making payments into a separate trust. The Company contributed 3,200,000 shares of common stock to this separate trust with an aggregate contribution value of approximately $ 39,136 on the contribution date. As a result of the contribution, the Company expects the approximately $ 14,700 required cash contribution to its U.S. defined benefit pension plans for the fiscal year ending March 31, 2024, to be reduced to zero , and the excess contribution value will reduce future required cash contributions. In addition to the defined benefit pension plans, the Company provides certain healthcare benefits for eligible retired employees. Such benefits are unfunded. No active employees are eligible for these benefits. The vast majority of eligible retirees receive a fixed-dollar benefit they can use to purchase healthcare services. A small number of eligible retirees receive traditional retiree medical benefits for which the company pays all premiums. All retirees who are eligible for these traditional benefits are Medicare-eligible. Current plan documents reserve the right to amend or terminate the plans at any time, subject to applicable collective bargaining requirements for represented employees. In accordance with the Compensation – Retirement Benefits topic of ASC 715, the Company has recognized the funded status of the benefit obligation as of the date of the last re-measurement, on the accompanying condensed consolidated balance sheets. The funded status is measured as the difference between the fair value of the plan’s assets and the pension benefit obligation or accumulated postretirement benefit obligation, of the plan. In order to recognize the funded status, the Company determined the fair value of the plan assets. The majority of the plan assets are publicly traded investments, which were valued based on the market price as of the date of re-measurement. Investments that are not publicly traded were valued based on the estimated fair value of those investments based on the Company's evaluation of data from fund managers and comparable market data or using the net asset value as a practical expedient. Net Periodic Benefit Plan Costs The components of net periodic benefit income for the Company's postretirement benefit plans are shown in the following table: Pension Benefits Three Months Ended December 31, Nine Months Ended December 31, 2023 2022 2023 2022 Components of net periodic benefit income: Service cost $ 100 $ 169 $ 300 $ 511 Interest cost 20,117 16,290 60,350 48,869 Expected return on plan assets ( 26,252 ) ( 30,326 ) ( 78,754 ) ( 90,973 ) Amortization of prior service credits 26 26 77 77 Amortization of net loss 7,523 7,725 22,568 23,174 Net periodic benefit expense (income) $ 1,514 $ ( 6,116 ) $ 4,541 $ ( 18,342 ) The Company recognized net periodic benefit income from its other postretirement benefits plan of approximately $ 4,467 and $ 4,581 for the nine months ended December 31, 2023 and 2022, respectively.

Segments

Segments	9 Months Ended
	Dec. 31, 2023
Segment Reporting [Abstract]
Segments	11. SEGMENTS The Company reports financial performance based on the following two reportable segments: Systems & Support and Interiors. The Company’s reportable segments are aligned with how the business is managed, and the Company's views of the markets it serves. The Chief Operating Decision Maker (the "CODM") evaluates performance and allocates resources based upon review of segment information. The CODM utilizes earnings before interest, income taxes, depreciation and amortization, and pension (“Adjusted EBITDAP”) as a primary measure of segment profitability to evaluate performance of its segments and allocate resources. Financial information for Systems & Support differs from information reported in prior periods as this reportable segment no longer includes the results of operations of Product Support which have been reclassified for all periods as discontinued operations. Segment Adjusted EBITDAP is total segment revenue reduced by operating expenses (less depreciation and amortization) identifiable with that segment. Corporate includes general corporate administrative costs and any other costs not identifiable with one of the Company’s segments. The Company does not accumulate net sales information by product or service or groups of similar products and services, and therefore the Company does not disclose net sales by product or service because to do so would be impracticable.

Commitments And Contingencies [Abstract]
Commitments and Contingencies	12. COMMITMENTS AND CONTINGENCIES Environmental Matters Certain of the Company's business current or former operations and facilities are subject to a number of federal, state, local and foreign environmental laws and regulations. In August 2023, a panel of three arbitrators made an interim decision in an ongoing arbitration between Triumph Aerostructures, LLC (“TAS”), a wholly owned subsidiary of the Company, and Northrop Grumman Systems Corporation (“Northrop”) related to ongoing responsibility for environmental remediation costs at four formerly occupied properties that had been previously operated by Northrop. Although the interim decision indicated that TAS would have certain ongoing responsibility for remediation at the properties, given the ongoing nature of the dispute and unresolved claims for damages and counterclaims, it is not possible to reasonably estimate the extent of TAS’s economic responsibility as it pertains to three of the properties. Approximately $ 1,300 has been accrued as a legal judgment loss and is management's best estimate of the remediation costs at the remaining fourth property. Further hearing on the matter is anticipated to occur in the second half of fiscal 2024. TAS intends to vigorously defend itself in this matter, including potentially seeking to set aside any adverse decision from the arbitration panel. While the Company currently expects that the final resolution of this matter will not have a material effect on its results from operations and cash flows, the assessment is subjective and requires the exercise of judgment, and the ultimate impact on operations could be in the range of a loss of up to $ 27,000 , with such loss resulting in annual cash expenditures not likely to exceed $ 1,000 to $ 2,000 in a given year. Commercial Disputes and Litigation Throughout the course of the Company’s programs, disputes with suppliers or customers could arise regarding unique contractual requirements, quality, costs or impacts to production schedules. If the Company is unable to successfully and equitably resolve such claims and assertions, its business, financial condition, results of operations, customer relationships and related transactions could be materially adversely affected. In the ordinary course of business, the Company is involved in disputes, claims and lawsuits with employees, suppliers and customers, as well as governmental and regulatory inquiries, that it deems to be immaterial. Some may involve claims or potential claims of substantial damages, fines, penalties or injunctive relief. While the Company cannot predict the outcome of any pending or future litigation or proceeding and no assurances can be given, the Company does not believe that any pending matter will have a material effect, individually or in the aggregate, on its financial position or results of operations. Divestitures, Disposals, Guarantees, and Indemnifications As disclosed in Note 3, we have engaged in a number of divestitures. In connection with divestitures and related transactions, the Company from time to time has indemnified and has been indemnified by third parties against certain liabilities that may arise in connection with, among other things, business activities prior to the completion of the respective transactions. The term of these indemnifications, which typically pertain to environmental, tax and product liabilities, is generally indefinite. As of December 31, 2023, no indemnification assets or liabilities have been recorded. As it relates to certain divestitures, disputes have arisen or may continue to arise between the Company and the acquirer subsequent to the completion and closing of the divestiture transaction. Such disputes have included or may include amounts payable to or from the buyer for closing working capital adjustments to the purchase price as well as claims regarding alleged violations of contractual terms, representations, and warranties of the sale agreements, among other matters. The outcome of such disputes typically involve negotiations between the Company and the acquirer, but could also lead to litigation between the parties, including as disclosed further below, and the ultimate claims made by the parties against each other could be material. As of December 31, 2023, we have accrued for our estimate of probable losses associated with such disputes, but losses in excess of those currently accrued could be incurred and may be material. The Company has received notification of claims which allege certain bases for indemnification and damages relating to certain divestitures. The relevant agreements generally contain limits on certain damages that may be payable under the relevant agreements. For example, the divestiture agreement relating to the sale of the Stuart facility contains an $ 18,750 general cap on breaches of representations (other than certain specified representations) and a $ 25,000 cap on breaches of certain specified representations related to contracts and product warranties, in each case absent certain circumstances, including fraud or breaches of fundamental or tax representations. As disclosed in Note 3, on June 16, 2023, the Company entered into a settlement agreement with the buyer of the Stuart facility resolving a working capital dispute with the buyer resulting in an amount of $ 2,400 payable to the Company and resolving claims by the buyer related to the accounts payable representation and warranty under the purchase agreement resulting in an amount of $ 9,200 payable to the buyer, with such amount applicable to the general cap referred to above. The amounts were settled on a net basis by the Company paying $ 6,800 to the buyer. The purchaser of the Stuart facility also commenced litigation against the Company on December 12, 2023, seeking additional indemnification for damages claimed to be approximately $ 130,000 for losses allegedly arising from the knowing breach of certain representations and warranties regarding the financial condition of TAS and the products manufactured by TAS and alleged failures to disclose known and widespread paint issues and certain supplier and production issues at the facility prior to the closing. While the Company cannot predict the outcome of any pending or future litigation, proceeding, or claim and no assurances can be given, the Company intends to vigorously defend claims brought against it and does not believe that any pending matter will have a material effect, individually or in the aggregate, on its financial position or results of operations. If the Company is unable to successfully and equitably resolve such claims and assertions, its business, financial condition, and results of operations could be materially adversely affected. Additionally, in connection with certain divestitures, the Company has obtained customer consent to assign specified long-term contracts to the acquirer of the divested business by entering into consent-to-assignment agreements among the customer, the acquirer, and the Company. Pursuant to certain of these agreements, the Company remains a co-obligor under the contract pursuant to guarantee agreements with the customer that predate the divestiture transaction. The term of these obligations typically covers a period of 2 to 5 years from the date of divestiture. There is no limitation to the maximum potential future liabilities under these contracts; however, the Company is typically indemnified by acquirers against such losses that may arise from the acquirers’ failure to perform under the assigned contracts. As of December 31, 2023 , no related indemnification assets or liabilities or guarantee liabilities have been recorded, and the Company has not been called upon to act as co-obligor under such arrangements through that date. Also, in connection with certain divestitures, the Company has assigned lease facility agreements to the acquirers and entered into agreements to act as a co-obligor under the lease agreement in the event of non-performance under the lease by the assignee. The Company is generally indemnified by the assignee or other third party to the transaction. On May 2, 2023, the Company received a letter from a lessor associated with one such transaction to assert the lessor’s rights against the Company as guarantor. The lease payment associated with the lease is approximately $ 130 per month over a lease term ending December 31, 2031, although the landlord has acknowledged its duty to mitigate damages by re-leasing the property. The Company expects to be fully indemnified for any amounts payable under such guarantee. As the Company has completed the disposal of certain facilities, it may be exposed to additional costs such as environmental remediation obligations, lease termination costs, or customer or supplier claims which may have a material effect on its financial position or results of operations when such matters arise and a reasonable estimate of the costs can be made. For example, in the year ended March 31, 2023, the Company withdrew from the IAM National Pension Fund (the “Fund), which is a multiemployer pension plan to which the Company previously contributed on behalf of certain of its represented employees. Such withdrawal occurred as part of the Company’s exit of its Spokane, Washington, composites manufacturing operations. In April 2023, the Company received a letter from the Fund confirming the Company’s complete withdrawal from the Fund and indicating that the Company’s portion of the unfunded vested benefits (the “Withdrawal Liability”) was estimated to be approximately $ 14,644 , payable in quarterly installments of approximately $ 400 over a period of approximately thirteen years. The Withdrawal Liability is subject to further adjustment based on the finalization of the Fund’s actuarial valuation for the plan year ending December 31, 2021, (i.e., the applicable plan year preceding the date of the Company’s withdrawal). As of December 31, 2023, the Company's liability for this obligation is included on the accompanying condensed consolidated balance sheets is approximately $ 13,415 , representing its estimate of the remaining obligation based on the letter received from the Fund. The Company is in the process of reviewing and responding to the withdrawal liability assessment, and it is possible the Withdrawal Liability could be reduced during that process.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended

Accounting Policies [Abstract]
Revenue Recognition and Contract Balances	Revenue Recognition and Contract Balances The Company's revenue is principally from contracts with customers to provide design, development, manufacturing, and support services associated with specific customer programs. The Company regularly enters into long-term master supply agreements that establish general terms and conditions and may define specific program requirements. Many agreements include clauses that provide sole supplier status to the Company for the duration of the program’s life. Purchase orders (or authorizations to proceed) are issued pursuant to the master supply agreements. Additionally, a majority of the Company’s agreements with customers include options for future purchases. Such options primarily reduce the administrative effort of issuing subsequent purchase orders and do not represent material rights granted to customers. The Company generally enters into agreements directly with its customers and is the principal in all current contracts. The identification of a contract with a customer for purposes of accounting and financial reporting requires an evaluation of the terms and conditions of agreements to determine whether presently enforceable rights and obligations exist. Management considers a number of factors when making this evaluation that include, but are not limited to, the nature and substance of the business exchange, the specific contractual terms and conditions, the promised products and services, the termination provisions in the contract, as well as the nature and execution of the customer’s ordering process and how the Company is authorized to perform work. Generally, presently enforceable rights and obligations are not created until a purchase order is issued by a customer for a specified number of units of product or services. Therefore, the issuance of a purchase order is generally the point at which a contract is identified for accounting and financial reporting purposes. Management identifies the promises to the customer. Promises are generally explicitly stated in each contract, but management also evaluates whether any promises are implied based on the terms of the agreement, past business practice, or other facts and circumstances. Each promise is evaluated to determine if it is a performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service. The Company considers a number of factors when determining whether a promise is a distinct performance obligation, including whether the customer can benefit from the good or service on its own or together with other resources that are readily available to the customer, whether the Company provides a significant service of integrating goods or services to deliver a combined output to the customer, or whether the goods or services are highly interdependent. The Company’s performance obligations consist of a wide range of engineering design services and manufactured components, as well as spare parts and repairs for OEMs. The transaction price for a contract reflects the consideration the Company expects to receive for fully satisfying the performance obligations in the contract. Typically, the transaction price consists solely of fixed consideration but may include variable consideration for contractual provisions such as unpriced contract modifications, cost-sharing provisions, and other receipts or payments to customers. The Company identifies and estimates variable consideration, typically at the most likely amount the Company expects to receive from its customers. Variable consideration is only included in the transaction price to the extent it is probable that a significant reversal of cumulative revenue recognized for the contract will not occur, or when the uncertainty associated with the variable consideration is resolved. Consideration paid or payable to a customer is reflected as a reduction in net revenues when the amounts paid are not related to a distinct good or service at the later of when the related revenue is recognized or when the Company pays or promises to pay the consideration to the customer. The Company's contracts with customers generally require payment under normal commercial terms after delivery with payment typically required within 30 to 120 days of delivery. The Company generally is not subject to collecting sales tax and has made an accounting policy election to exclude from the transaction price any sales and other similar taxes collected from customers. As a result, any such collections are accounted for on a net basis. The total transaction price is allocated to each of the identified performance obligations using the relative stand-alone selling price. The objective of the allocation is to reflect the consideration that the Company expects to receive in exchange for the products or services associated with each performance obligation. Stand-alone selling price is the price at which the Company would sell a promised good or service separately to a customer. Stand-alone selling prices are established at contract inception, and subsequent changes in transaction price are allocated on the same basis as at contract inception. When stand-alone selling prices for the Company’s products and services are not observable, the Company uses either the “Expected Cost Plus a Margin” or "Adjusted Market Assessment" approaches to estimate stand-alone selling price. Expected costs are typically derived from the available periodic forecast information. Revenue is recognized when or as control of promised products or services transfers to a customer and is recognized at the amount allocated to each performance obligation associated with the transferred products or services. Service sales, principally representing repair, maintenance, and engineering activities are recognized over the contractual period or as services are rendered. Sales under long-term contracts with performance obligations satisfied over time are recognized using either an input or output method. The Company recognizes revenue over time as it performs on these contracts because of the continuous transfer of control to the customer as represented by contractual terms that entitle the Company to the reimbursement of costs plus a reasonable profit for work performed to manufacture products for which the Company has no alternate use or for work performed on a customer-owned asset. With control transferring over time, revenue is recognized based on the extent of progress toward completion of the performance obligation. The Company generally uses the cost-to-cost input method of progress for its contracts because it best depicts the transfer of control to the customer that occurs as work progresses. Under the cost-to-cost method, the extent of progress toward completion is measured based on the proportion of costs incurred to date to the total estimated costs at completion of the performance obligation. The Company reviews its cost estimates on contracts on a periodic basis, or when circumstances change and warrant a modification to a previous estimate. Cost estimates are largely based on negotiated or estimated purchase contract terms, historical performance trends, and other economic projections. Significant factors that influence these estimates include inflationary trends, technical and schedule risk, internal and subcontractor performance trends, business volume assumptions, asset utilization, and anticipated labor agreements. Revenue and cost estimates are regularly monitored and revised based on changes in circumstances. Impacts from changes in estimates of net sales and cost of sales are recognized on a cumulative catch-up basis, which recognizes in the current period the cumulative effect of the changes on current and prior periods based on a performance obligation’s percentage of completion. Forward loss reserves for anticipated losses on long-term contracts are recorded in full when such losses become evident, to the extent required, and are included in contract liabilities on the accompanying condensed consolidated balance sheets. The Company believes that the accounting estimates and assumptions made by management are appropriate; however, actual results could differ materially from those estimates. For the three and nine months ended December 31, 2023, cumulative catch-up adjustments resulting from changes in estimated contract values and contract costs during the periods were immaterial. For the three months ended December 31, 2022 , cumulative catch-up adjustments resulting from changes in estimates increased net sales, operating income, net income, and earnings per diluted share by approximately $ 1,459 , $ 748 , $ 748 , and $ 0.01 , respectively. For the nine months ended December 31, 2022 , cumulative catch-up adjustments resulting from changes in estimates increased net sales, operating income, net income, and earnings per diluted share by approximately $ 13,360 , $ 20,151 , $ 20,151 , and $ 0.30 , respectively. Revenues for performance obligations that are not recognized over time are recognized at the point in time when control transfers to the customer. For performance obligations that are satisfied at a point in time, the Company evaluates the point in time when the customer can direct the use of and obtain the benefits from the products and services. Generally, the shipping terms determine the point in time when control transfers to customers. Shipping and handling activities are not considered performance obligations and related costs are included in cost of sales as incurred. Differences in the timing of revenue recognition and contractual billing and payment terms result in the recognition of contract assets and liabilities. Refer to Note 4 for further discussion.
Concentration of Credit Risk	Concentration of Credit Risk The Company’s trade and other accounts receivable are exposed to credit risk. However, the risk is limited due to the diversity of the customer base and the customer base’s wide geographical area. Trade accounts receivable from The Boeing Company ("Boeing") (representing commercial, military, and space) represented approximately 13 % and 13 % of total trade accounts receivable, including receivables presented within assets held for sale - current, as of December 31, 2023 and March 31, 2023 , respectively. As of March 31, 2023, trade and other receivables from Daher Aerospace Inc. ("Daher") include receivables that largely corresponded with payables associated with transition services and represented approximately 20 % as of March 31, 2023. The transition services agreement with Daher contractually expired as of June 30, 2023, and remaining receivables and payables as of that date were not significant. The Company had no other concentrations of credit risk of more than 10%. Sales to Boeing from continuing operations for the nine months ended December 31, 2023, were $ 200,577 , or 24 % of net sales, of which $ 123,323 and $ 77,254 were from Systems & Support and Interiors, respectively. Sales to Boeing for the nine months ended December 31, 2023, included within discontinued operations were approximately $ 31,366 . Sales to Boeing from continuing operations for the nine months ended December 31, 2022, were $ 238,750 , or 30 % of net sales, of which $ 110,290 and $ 128,460 were from Systems & Support and Interiors, respectively. Sales to Boeing for the nine months ended December 31, 2022, included within discontinued operations were approximately $ 27,066 . No other single customer accounted for more than 10% of the Company’s net sales. However, the loss of any significant customer, including Boeing, could have a material adverse effect on the Company and its operating subsidiaries.
Warrants	Warrants On December 1, 2022, the Company’s board of directors declared a distribution to holders of the Company’s shares of common stock in the form of warrants to purchase shares of common stock (the “Warrants”). Holders of common stock received three Warrants for every ten shares of common stock held as of December 12, 2022 (the "Record Date"). The Company issued approximately 19.5 million Warrants on December 19, 2022, to holders of record of common stock as of the close of business on the Record Date. Each Warrant represented the right to purchase initially one share of common stock, at an exercise price of $ 12.35 per Warrant, subject to certain anti-dilution adjustments. Payment for shares of common stock on exercise of Warrants could have been made in (i) cash or (ii) under certain circumstances, certain of the Company's outstanding notes (the "Designated Notes"). The common stock warrants are accounted for as derivative liabilities in accordance with ASC 815-40 and included within accrued liabilities on the accompanying condensed consolidated balance sheets. The Company measured the Warrants at fair value as of the issuance date using a Monte Carlo pricing model, a Level 3 fair value measurement (as described below), due to the level of market activity. Inherent in the option pricing simulation are assumptions related to expected stock-price volatility, expected life and risk-free interest rate. The Company estimates the volatility of the Warrants based on implied and historical volatility of the Company’s common stock. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected remaining life of the Warrants. The expected life of the Warrants is based on the Company’s ability to redeem the Warrants, subject to a 20 calendar-day notice period, as well as the automatic acceleration of the Expiration Date following the Price Condition Date. During the three months ended December 31, 2022, due to increased trading volume, the Company began remeasuring outstanding Warrants using the Warrants trading price, a Level 1 fair value measurement (as described below). The Warrants are remeasured at each balance sheet date. Warrants remeasurement adjustments are recognized in warrant remeasurement gain, net on the accompanying condensed consolidated statements of operations. At distribution, the fair value of the Warrants was $ 19,500 . Approximately 7.7 million of Warrants were exercised in the six months ended September 30, 2023, resulting in total cash proceeds, net of transaction costs, of approximately $ 79,961 , and $ 8,532 of warrants remeasurement gain was recognized in the six months ended September 30, 2023. On July 6, 2023 , the Company redeemed all of the approximately 11.4 million remaining outstanding Warrants for a total redemption price of approximately $ 11 pursuant to its June 16, 2023, notice of redemption.
Contingencies	Contingencies Contingences are existing conditions, situations or circumstances involving uncertainty as to possible gain or loss that will ultimately be resolved when future events occur or fail to occur. Such contingencies include, but are not limited to environmental obligations, litigation, regulatory investigations and proceedings, product quality, and gains or losses resulting from other events and developments. Liabilities for loss contingencies are accrued in the amount of the Company's best estimate for the ultimate loss when a loss is considered probable of having been incurred and is reasonably estimable. When there appears to be a range of possible costs with equal likelihood, liabilities are based on the low-end of such range. Disclosure is provided for material loss contingencies when a loss is probable but a reasonable estimate cannot be made, and when it is reasonably possible that a loss will be incurred or the amount of a loss will exceed the recorded provision. The Company regularly reviews contingencies to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the loss or range of loss can be made. Contingencies that might result in gains are generally not accrued until the contingencies are resolved and the gain is realized or realizable. Refer to Note 12 for further disclosure.
Fair Value Measurements	Fair Value Measurements Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. When determining fair value measurements for assets and liabilities required to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact and also considers assumptions that market participants would use when pricing an asset or liability. The fair value hierarchy has three levels of inputs that may be used to measure fair value: Level 1—Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2—Unadjusted quoted prices in active markets for similar assets or liabilities, or unadjusted quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability; and Level 3—Unobservable inputs for the asset or liability. The Company has applied fair value measurements when measuring the warrants (refer to the above disclosure), when disclosing the fair value of its long-term debt not recorded at fair value (see Note 6), and to its pension and postretirement plan assets (see Note 9).
Supplemental Cash Flow Information	Supplemental Cash Flow Information For the nine months ended December 31, 2023 and 2022 the Company paid $ 4,962 and $ 3,838 , respectively f or income taxes, net of income tax refunds received.

Debt instrument, redemption, description	On February 6, 2024, the Company provided holders of the 2028 First Lien Notes with a conditional notice of redemption to redeem approximately $120,000 of the 2028 First Lien Notes (as defined in Note 6 below) at a redemption price equal to 103% of the aggregate principal amount plus accrued and unpaid interest. The Company also provided holders of the 2025 Notes (as defined in Note 6 below) with a conditional notice of redemption to redeem up to all of the outstanding 2025 Notes at 100% of the aggregate principal amount plus accrued and unpaid interest. Both redemptions are conditioned on the closing of the sale of Product Support, and the unsecured redemption will only occur after the Company conducts an asset sale offer whereby it will first offer the proceeds allocated to redeem the 2025 Notes to repurchase the 2028 First Lien Notes at 100% of the aggregate principal amount plus accrued and unpaid interest. In the event that the Company redeems more than $140,000 of the 2028 First Lien Notes pursuant to the asset sale offer, the redemption of the 2025 Notes will be reduced dollar-for-dollar by the amount of the 2028 First Lien Notes that are redeemed above $140,000. If the Company redeems more than $575,621 of 2028 First Lien Notes pursuant to the asset sale offer, the redemption of the 2025 Notes will not occur.
