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 ~~six~~nine months ended ~~September 30,~~December 31, 2020 and 2019, are not necessarily indicative of results that may be expected for the year ending March 31, 2021. The accompanying condensed consolidated financial statements are unaudited and should be read in conjunction with the fiscal 2020 audited consolidated financial statements and notes thereto included in the Company's Form 10-K for the fiscal year ended March 31, 2020, filed with the Securities and Exchange Commission (the "SEC") on May 28, 2020.

Triumph 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 2 reportable segments: Systems & Support and 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; hydromechanical and electromechanical primary and secondary flight controls. Systems & Support also provides full life cycle solutions for commercial, regional and military aircraft. The Company’s extensive product and service offerings include full post-delivery value chain services that simplify the maintenance, repair, and overhaul (“MRO”) supply chain. Through its ground support equipment maintenance, component MRO and post-production supply chain activities, Systems & Support is positioned to provide integrated planeside repair solutions globally. Capabilities include metallic and composite aircraft structures; nacelles; thrust reversers; interiors; auxiliary power units; and a wide variety of pneumatic, hydraulic, fuel and mechanical accessories. Repair services generally involve the replacement and/or remanufacturing of parts, which is similar to the original manufacture of the part. The processes that the Company performs related to repair and overhaul services are essentially the repair of wear parts or replacement of parts that are beyond economic repair. The repair service generally involves remanufacturing a complete part or a component of a part.

Aerospace Structures consists of the Company’s operations that supply commercial, business, regional and military manufacturers with large metallic and composite structures and aircraft interior systems, including air ducting and thermal acoustic insulations systems. Products include wings; wing boxes; fuselage panels; horizontal and vertical tails; subassemblies such as floor grids; and aircraft interior systems, including air ducting and thermal acoustic insulations 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.

In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This ASU modifies the measurement of expected credit losses of certain financial instruments. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods. The amendments in this ASU should be applied on a modified retrospective basis to all periods presented. The Company adopted ASU 2016-13 effective April 1, 2020, and the impact on our consolidated financial statements of adoption was not significant.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. This ASU modifies the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosures. ASU 2018-13 is effective for annual periods beginning after December 15, 2019, and interim periods within those annual periods, with early adoption permitted. The amendments on changes ~~in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value~~

in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company adopted ASU 2018-13 effective April 1, 2020, and the adoption did not have a significant impact on its consolidated financial statement disclosures.

In August 2018, the FASB issued ASU 2018-14, Compensation—Retirement Benefits—Defined Benefit Plans—General (Subtopic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans, which modifies the annual disclosure requirements for defined benefit pension plans and other postretirement plans. The ASU does not modify interim disclosure requirements. ASU 2018-14 is effective for annual periods ~~beginning~~ending after December 15, 2020, with early adoption permitted. The amendments in this ASU should be applied on a retrospective basis to all periods presented. As the ASU does not modify interim disclosure requirements, the Company is currently evaluating the effect that ASU 2018-14 will have on its annual consolidated financial statements and related disclosures.

Effective April 1, 2020, the Company changed its method of accounting for the determination of the market-related value of assets (“MRVA”) for a class of assets (fixed income securities) within the qualified U.S. defined benefit plan (the “Plan”) which is used in determining the expected return on asset component of net periodic benefit income. This class of assets is comprised solely of the fixed income securities asset class held in the portfolio for the Plan, which provides a natural hedge (liability-hedging assets) against the changes in the recorded amount of net periodic pension cost. Refer to Note 15 in the Company’s Form 10-K for the fiscal year ended March 31, 2020, for its fair value disclosure by asset classification. The Company’s previous method of accounting was to calculate the MRVA for all the Plan’s assets recognizing investment gains and losses into the MRVA over a five-year period. The Company has changed its method of accounting and elected to use the fair value of our fixed income assets, which represent approximately 44% of the Plan’s assets, to determine the MRVA beginning in the second quarter of fiscal 2021. This change in accounting principle is preferable as it results in an expected return on asset component of net periodic benefit income that more accurately reflects the changes in the fair values of the fixed income securities. No change is being made to the accounting principle for the other classes of pension assets, which represent the remaining 56% of the pension asset portfolio for the Plan. The gains and losses for these other plan assets will continue to be amortized into the MRVA over a five-year period.

The change in accounting principle requires retrospective application and prospective disclosure. The Company applied the change effective April 1, 2020, and recorded a cumulative adjustment to equity as ~~for~~of the earliest period presented. The tables below represent the impact of this change on the condensed consolidated statements of operations (including earnings per share) and the condensed consolidated statements of comprehensive ~~loss~~(loss) income for the periods presented below. The change in accounting principle had no impact on the condensed consolidated statements of cash flows for these periods.

The tables below represent the impact of the change in accounting principle on the condensed consolidated statement of operations and the condensed consolidated statements of comprehensive loss for the three and ~~six~~nine months ended ~~September 30,~~December 31, 2020.

The table below represents the impact of the change in accounting principle on the condensed consolidated balance sheet as of March 31, 2020.

The preparation of the financial statements in conformity with U.S. GAAP 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.

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. 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. However, a subset of the Company’s current contracts includes significant financing components because the timing of the transfer of the underlying products and services under contract are at the customers’ discretion. For these contracts, the Company adjusts the transaction price to reflect the effects of the time value of money.

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 given the increased uncertainties surrounding the severity and duration of the impacts of the COVID-19 pandemic; however, actual results could differ materially from those estimates.

For the three months ended ~~September 30,~~December 31, 2020, cumulative catch-up adjustments resulting from changes in contract values and estimated costs that arose during the fiscal year decreased revenue, operating loss, net loss and loss per share by approximately ($37), $3,688, $3,688, and $0.07, respectively. For the three months ended December 31, 2019, cumulative catch-up adjustments resulting from changes in estimates increased net sales by approximately $4,722 and decreased operating income, net income, and earnings per share by approximately ($210), ($166), and $0.00, respectively.

For the nine months ended December 31, 2020, cumulative catch-up adjustments resulting from changes in contract values and estimated costs that arose during the fiscal year increased revenue and decreased operating loss, net loss and loss per share by approximately ~~$1,299, $10,052, $10,052,~~$4,577, $19,349, $19,349, and ~~$0.19,~~$0.37, respectively. For the ~~three~~nine months ended ~~September 30,~~December 31, 2019, cumulative catch-up adjustments resulting from changes in estimates increased net sales by approximately ~~$3,189~~$2,347 and decreased operating income, net income, and earnings per share by approximately ($~~5,127)~~16,393), ($~~4,050)~~12,950), and ($~~0.08), respectively.~~

For the six months ended September 30, 2020, cumulative catch-up adjustments resulting from changes in contract values and estimated costs that arose during the fiscal year increased revenue and decreased operating loss, net loss and loss per share by approximately $3,253, $13,647, $13,647, and $0.26, respectively. For the six months ended September 30, 2019, cumulative catch-up adjustments resulting from changes in estimates increased net sales by approximately $1,245 and decreased operating income, net income, and earnings per share by approximately ($12,270), ($9,693), and ($0.19)0.26), 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 contract assets and liabilities. Refer to Note 4 for further discussion.

In connection with several prior acquisitions, the Company assumed existing long-term contracts. Based on review of these contracts at the acquisition date, the Company concluded that the terms of certain contracts were either more or less favorable than could be realized in market transactions as of the date of the acquisition. As a result, the Company recognized acquired contract liabilities, net of acquired contract assets as of the acquisition date of each respective acquisition, based on the present value of the difference between the contractual cash flows of the executory contracts and the estimated cash flows had the contracts been executed at the acquisition date. The liabilities principally relate to long-term contracts that were initially executed several years prior to the respective acquisition. The Company measured these net liabilities in the year they were acquired under the measurement provisions of Accounting Standards Codification (“ASC”) 820, Fair Value Measurement, which is based on the price to transfer the obligation to a market participant at the measurement date, assuming that the net liabilities will remain outstanding in the marketplace. The portion of the Company's revenue resulting from transactions other than contracts with customers pertains to the amortization of these acquired contract ~~liabilities.~~liabilities as the related contractual performance obligations are satisfied. Adjustments to these liabilities due to significant changes in the total estimated costs of the contract are accounted for in a manner consistent with other loss contract reserves, with such adjustments recognized in cost of sales.

Trade and other receivables are recorded net of an allowance for expected credit losses. Trade and other receivables include amounts billed and currently due from customers and amounts retained by the customer pending contract completion. The Company performs ongoing credit evaluations of its customers and generally does not require collateral. The Company pools receivables that share underlying risk characteristics and records the 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. The Company writes off balances against the allowance for expected credit losses when collectibility is deemed remote. The Company's trade and other receivables are exposed to credit risk; however, the risk is limited due to the diversity of the customer base. For the three and ~~six~~nine months ended ~~September 30,~~December 31, 2020 and 2019, credit loss expense and write-offs were immaterial.

The Company leases office space, manufacturing facilities, land, vehicles, and equipment. The Company determines if an agreement is or contains a lease at the lease inception date and recognizes right-of-use (“ROU”) assets and lease liabilities at the

lease commencement date. A ROU asset and corresponding lease liability are not recorded for leases with an initial term of 12 months or less (“short-term leases”).

ROU assets represent the Company's right to use an underlying asset during the lease term, and lease liabilities represent the Company's obligation to make lease payments arising from the lease. The determination of the length of lease terms is affected by

options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. The existence of significant economic incentive is the primary consideration when assessing whether the Company is reasonably certain of exercising an option in a lease. Both finance and operating lease ROU assets and liabilities are recognized at commencement date and measured as the present value of lease payments to be made over the lease term. As the interest rate implicit in the lease is not readily available for most of the Company's leases, the Company uses its estimated incremental borrowing rate in determining the present value of lease payments. The estimated incremental borrowing rate is derived from information available at the lease commencement date. The lease ROU asset recognized at commencement is adjusted for any lease payments related to initial direct costs, prepayments, and lease incentives.

For operating leases, lease expense is recognized on a straight-line basis over the lease term. For finance leases, lease expense comprises the amortization of the ROU assets recognized on a straight-line basis generally over the shorter of the lease term or the estimated useful life of the underlying asset and interest on the lease liability. Variable lease payments not dependent on a rate or index are recognized when the event, activity, or circumstance in the lease agreement upon which those payments are contingent is probable of occurring and are presented in the same line of the consolidated balance sheet as the rent expense arising from fixed payments. The Company has lease agreements with lease and non-lease components. Non-lease components are combined with the related lease components and accounted for as lease components for all classes of underlying assets.

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 ~~16%~~19% and 21% of total trade accounts receivable as of ~~September 30,~~December 31, 2020 and March 31, 2020, respectively. Trade and other accounts receivable from Bombardier Inc. ("Bombardier") include receivables from transition services and represented approximately ~~13%~~2% and 16% as of ~~September 30,~~December 31, 2020 and March 31, 2020, respectively. The Company had no other concentrations of credit risk of more than 10%.

Sales to Boeing for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, were ~~$361,770,~~$528,263, or ~~37%~~38% of net sales, of which ~~$104,547~~$164,520 and ~~$257,224~~$363,743 were from ~~the~~ Systems & Support and Aerospace Structures, respectively. Sales to Boeing for the ~~six~~nine months ended ~~September 30,~~December 31, 2019, were ~~$510,934,~~$742,495, or 34% of net sales, of which ~~$128,477~~$189,854 and ~~$382,457~~$552,641 were from ~~the~~ Systems & Support and Aerospace Structures, respectively. The percentage increase in sales to Boeing as compared with the prior period is driven entirely by military sales.

Sales to Gulfstream Aerospace Corporation (“Gulfstream”) for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, were ~~$90,203,~~$100,364, or 9%7% of net sales, of which ~~$1,764~~$2,166 and ~~$88,440~~$98,197 were from ~~the~~ Systems & Support and Aerospace Structures, respectively. Sales to Gulfstream for the ~~six~~nine months ended ~~September 30,~~December 31, 2019, were ~~$187,689,~~$268,917, or 12% of net sales, of which ~~$1,716~~$2,497 and ~~$185,973~~$266,421 were from ~~the~~ Systems & Support and Aerospace Structures, respectively.

No other single customer accounted for more than 10% of the Company’s net sales. However, the loss of any significant customer, including Boeing and Gulfstream, could have a material adverse effect on the Company and its operating subsidiaries.

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 impairment of assets held for sale (see Note 3), when measuring the long-lived asset impairment in the current period (see Note 10), and to its pension and postretirement plan assets (see Note 11).

For the ~~six~~nine months ended ~~September 30,~~December 31, 2020, the Company paid ~~$1,281~~$2,474 for income taxes, net of income tax refunds received. For the ~~six~~nine months ended ~~September 30,~~December 31, 2019, the Company paid ~~$2,724~~$4,370 for income taxes, net of income tax refunds received.

In May 2020, the Company’s Board of Directors committed to a plan to sell its composites manufacturing operations located in Milledgeville, Georgia and Rayong, Thailand. In August 2020, the Company entered into a definitive agreement with the buyer of the composites manufacturing operations in Georgia and Thailand. The transaction is expected to close in the ~~second half~~fourth quarter of fiscal ~~2021,~~year 2021. In the three months ended December 31, 2020, the Company recognized an impairment on the assets held for sale of $45,201 due to decreases in actual and expected performance of certain widebody programs within the disposal group that affected its estimated fair value less cost to sell. The impairment is presented on the accompanying consolidated statements of operations within loss on sale of assets and businesses. To measure the amount of the impairment, the Company compared the carrying value of the assets and liabilities of the disposal group with their estimated fair value less cost to sell as of the balance sheet date. The estimate of fair value is categorized as Level 2 within the fair value hierarchy. The key assumptions used in the estimate of fair value is the negotiated sales price of the assets and the ~~resulting gain or loss is not expected to be significant.~~assumption of the disposal group’s liabilities. As of ~~September 30,~~December 31, 2020, the operating results of the composites manufacturing operations are included within the Aerospace Structures reportable segment, and the related assets and liabilities are classified as held for sale on the accompanying condensed consolidating balance sheets.

In August 2020, the Company completed the transfer of the assets and certain liabilities associated with its Gulfstream G650 wing supply chain activities for cash proceeds net of transaction costs of approximately $52,000. The Company recognized a loss of approximately $747, which is presented on the accompanying condensed consolidated statements of operations within loss on sale of assets and businesses. The operating results of associated with the G650 wing supply chain activities were included within Aerospace Structures through the date of transfer.

In December 2019, the Company completed the sale of its manufacturing operations at its Nashville, TN, facility for cash proceeds net of transaction costs of approximately $58,000, including approximately $7,000 allocated as a premium paid by the buyer in exchange for a specified performance guarantee. The Company recognized a loss of approximately $64,000, which is presented on the consolidated statements of operations within loss on sale of assets and businesses. The operating results of the Nashville manufacturing operations are included in Aerospace Structures through the date of divestiture. Additionally, as part of the transaction, the Company agreed to transfer to the buyer, within 120 days from the date of closing, certain defined benefit pension assets and obligations of approximately $55,000 associated with the Nashville manufacturing operations. In accordance with applicable defined benefit pension plan accounting guidance, the transfer was treated as a settlement for purposes of the Company’s consolidated financial statements and resulted in accelerated recognition of previously unrecognized actuarial losses. The Company completed the transfer of the defined benefit pension assets and obligations in March 2020 and recognized a one-time settlement loss of approximately $28,000.

In September 2019, the Company completed the assignment of its E-2 Jets contract with Embraer for the manufacture of structural components for their program to AeroSpace Technologies of Korea Inc. ("ASTK"). As part of this transaction, the Company transferred certain assets and liabilities to ASTK and recognized a gain of approximately $10,000, which is presented on the accompanying condensed consolidated statements of operations within loss on sale of assets and businesses. The assets and liabilities transferred were included within Aerospace Structures through the date of divestiture.

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 13, Segments.

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 recognized when the revenue associated with the contract is recognized prior to billing and 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 six months ended September 30, 2020 and 2019, credit loss expense and write-offs related to contract assets were immaterial.~~

the three and nine months ended December 31, 2020 and 2019, 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 our 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, which 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 our contract assets and liabilities balances:

	September 30, 2020			March 31, 2020			Change			December 31, 2020			March 31, 2020			Change
Contract assets	$	209,424		$	267,079		$	(57,655	)	$	175,099		$	267,079		$	(91,980	)
Contract liabilities		(301,190	)		(386,585	)		85,395			(278,690	)		(386,585	)		107,895
Net contract liability	$	(91,766	)	$	(119,506	)	$	27,740		$	(103,591	)	$	(119,506	)	$	15,915

The Company recognized revenue due to changes in estimates associated with performance obligations satisfied or partially satisfied in previous periods of ~~$3,253.~~$4,577.

On August 17, 2020, the Company repaid the loans and other amounts outstanding under its revolving credit facility (the “Revolving Credit Facility”), which was governed by the Third Amended and Restated Credit Agreement, dated as of November 19, 2013 (as amended, the “Revolving Credit Agreement”) and terminated all commitment thereunder. The payment of $335,240 was made using a portion of the proceeds from the issuance of the Senior Secured First Lien Notes due 2024. The Company initially cash collateralized the letters of credit issued under the Revolving Credit Agreement but now have the ability to issue letters of credit under the Receivables Securitization Facility (as defined below).

On August 17, 2020, the Company entered into amendments to its receivables securitization facility (the “Receivables Securitization Facility”). The August amendments removed the covenants that required the Company to maintain certain financial ratios. As of ~~September 30,~~December 31, 2020, the maximum amount available under the Receivables Securitization Facility was $75,000, and the Company has the ability to reduce the facility amount to not less than $50,000. The actual amount available under the Receivables Securitization Facility at any point in time is dependent upon the balance of eligible accounts receivables as well as the amount of letters of credit outstanding.

On September 29, 2020, the Company entered into additional amendments to the Receivables Securitization Facility. The September amendments provide the Company with enhanced liquidity options by establishing a letter of credit facility under the Receivables Securitization Facility which effectively replaces a similar limited letter of credit facility under the Revolving Credit Facility Amendment. Pursuant to the letter of credit facility, the Company may request the Receivables 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 connection with the Receivables 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 Receivables Securitization Facility. Interest rates are based on the lesser of 0.75% or the London Interbank Offered Rate (“LIBOR”), plus a 2.50% fee on the drawn portion and 0.60% fee on the undrawn portion of the Receivables Securitization Facility. 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. At ~~September 30,~~December 31, 2020, there were $0 in borrowings and ~~$27,741~~$27,779 in letters of credit outstanding under the Receivables Securitization Agreement, primarily to support insurance policies. The Receivables Securitization Facility expires in December 2022.

The agreements governing the Receivables 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.

On August 17, 2020, the Company issued $700,000 principal amount of 8.875% Senior Secured First Lien Notes due 2024 (the “First Lien Notes”) pursuant to an indenture among the Company, the Guarantor Subsidiaries (as defined below) and U.S. Bank National Association, as trustee (the “First Lien Notes Indenture”). The First Lien Notes were sold at 100% of the principal amount and have an effective interest yield of 8.875%. Interest is payable semi-annually in cash in arrears on June 1 and December 1 of each year, commencing on December 1, 2020. In connection with the issuance of the First Lien Notes, the Company incurred approximately ~~$11,600~~$13,000 of costs, which were deferred and are being amortized over the term of the First Lien Notes.

The First Lien Notes and the guarantees are first lien secured obligations of the Company and the Guarantor Subsidiaries. The First Lien Notes:

The First Lien Notes are guaranteed on a full, senior secured, joint and several basis by each of the Company’s domestic restricted subsidiaries (the “Guarantor Subsidiaries”) that guarantees any of the Company’s Existing 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 First Lien Notes. Under certain circumstances, the guarantees may be released without action by, or consent of, the holder of the First Lien Notes.

The First Lien Notes and the guarantees will be 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 and will rank senior to those that secure the 2024 Notes (the “Collateral”). Under certain circumstances, the Collateral may be released without action by, or the consent of, the holders of the First Lien Notes. The 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.

Pursuant to an intercreditor agreement (the “Intercreditor Agreement”) between Wilmington Trust, National Association, in its capacity as the collateral trustee (the “Collateral Trustee”) and U.S. Bank National Association, in its capacity as second lien collateral agent for the 2024 Notes, the liens on the Collateral securing the First Lien Notes and all future first lien obligations will be made expressly senior to the liens securing the 2024 Notes.

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 First Lien Notes, will set forth therein the relative rights with respect to the Collateral as among the trustee for the 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 will generally control 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 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 First Lien Note holders may no longer be in control of such decisions.

The Company may redeem the First Lien Notes, in whole or in part, at any time or from time to time on or after February 1, 2023, 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 February 1, 2023, the Company may redeem the 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 First Lien Notes prior to June 1, 2023, with the net cash proceeds from certain equity offerings at a redemption price equal to 108.875% of their principal amount, together with 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 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 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 First Lien Notes Indenture requires, among other things, the Company to provide financial and current reports to holders of the First Lien Notes or file such reports electronically with the SEC. Furthermore, the First Lien Notes Indenture requires that the future net proceeds from certain asset sales will be required to repay the First Lien Notes at a premium of 106.656%, until the aggregate principal amount of Notes outstanding is $350,000 or less, provided that the Company may retain the first $100,000 of such net proceeds (subject to compliance with the asset sale covenants in the Company’s other outstanding indentures) or use it for certain other permitted purposes. 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.

On September 23, 2019, the Company issued $525,000 principal amount of 6.250% Senior Secured Notes due September 15, 2024 (the "2024 Notes"). The 2024 Notes were sold at 100% of principal amount and have an effective interest yield of 6.250%. Interest on the 2024 Notes is payable semiannually in cash in arrears on March 15 and September 15 of each year. The 2024 Notes are secured by second-priority liens on all of the Company's and the Guarantor Subsidiaries' assets that secure all of the indebtedness under the Credit Facility and certain hedging and cash management obligations.

On September 23, 2019, the Company called all outstanding 4.875% Senior Notes due 2021 (the "2021 Notes") and discharged the 2021 Notes by irrevocably depositing with the 2021 Notes trustee sufficient funds to pay all principal and accrued interest through October 23, 2019. On October 23, 2019, the Company redeemed $375,000 principal amount of the 2021 Notes with the proceeds of the 2024 Notes.

Interest on the 2025 Notes accrues at the rate of 7.750% per annum and is payable semiannually in cash in arrears on February 15 and August 15 of each year.

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:

September 30, 2020				March 31, 2020
December 31, 2020								December 31, 2020			March 31, 2020

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 our existing debt (Level 2 inputs).

Interest paid on indebtedness during the ~~six~~nine months ended ~~September 30,~~December 31, 2020 and 2019, amounted to ~~$52,806~~$79,382 and ~~$48,972,~~$60,885, respectively.

The Company follows the Income Taxes 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 de-recognition, 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 the 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 ~~September 30,~~December 31, 2020 and March 31, 2020, the total amount of unrecognized tax benefits was ~~$18,971~~$18,908 and $18,965, 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 ~~September 30,~~December 31, 2020, 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 these allowances. 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 2021 and future periods.

The effective income tax rate for the three months ended ~~September 30,~~December 31, 2020, was ~~(2.5)~~(1.0)% as compared with 21.0% for the three months ended ~~September 30,~~December 31, 2019. For the three months ended ~~September 30,~~December 31, 2020, the effective tax rate reflected a limitation on the recognition of tax benefits due to the full valuation allowance. The effective income tax rate for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, was ~~(0.5)~~(0.6)% as compared with 21.0% for the ~~six~~nine months ended ~~September 30,~~December 31, 2019. For the ~~six~~nine months ended ~~September 30,~~December 31, 2020, the effective tax rate reflected a limitation on the recognition of tax benefits due to the full valuation allowance.

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.

As of ~~September 30,~~December 31, 2020, the Company is not subject to any ongoing income tax examinations. The Company has ~~filed~~settled appeals infor a prior state examination related to fiscal years ended March 31, 1999 through March 31, 2005. The Company believes appropriate provisions for all outstanding issues have been made for all jurisdictions and all open years.

As disclosed in Note 3, in May 2020, the Company’s Board of Directors committed to a plan (i) to sell its composites manufacturing operations located in Milledgeville, Georgia and Rayong, Thailand and (ii) to transfer the assets and certain liabilities associated with its Gulfstream G650 wing supply chain activities (as disclosed in Note 3, this transaction closed in August 2020). These planned divestitures represent the divestiture of certain assets and liabilities of an operating business within the Aerospace Structures segment that the Company has identified as an asset group pursuant to the provisions of ASC 360, Property, Plant, and Equipment. As a result, as of May 31, 2020, the Company concluded that the planned divestitures represented a significant change in the manner in which the related asset group was expected to be used, and that the asset group therefore needed to be tested for recoverability. The asset group primarily consists of working capital, fixed assets and definite-lived intangible assets. The Company first determined that the relevant long-lived asset group was not recoverable by comparing the undiscounted cash flows expected to be generated by the long-lived asset group to the carrying value of the asset group. As a result, the Company estimated the fair value of the long-lived asset group and concluded that the asset group was impaired. The Company used a multi-period excess earnings approach to estimate the fair value of the long-lived asset group for purposes of testing the asset group for impairment. This method estimates fair value based on the expected future excess earnings stream attributable to the asset group. This method requires the use of several key assumptions, including revenue projections that consider historical and estimated future results, general economic and market conditions, as well as the impact of planned business and operational strategies. A discount rate of 15.0% was applied to the estimated future excess earnings and cash flows in order to estimate the fair value of the asset group as of the measurement date. The Company has determined that the lowest level of the inputs that are significant to the fair value measurement are unobservable inputs that fall within Level 3 of the fair value hierarchy.

In accordance with ASC 360, the Company allocated the resulting impairment to the specific long-lived assets within the asset group on a pro rata basis, except that the loss allocated to an individual long-lived asset of the group did not reduce the carrying amount of that asset below its estimated fair value. As a result, the Company recognized a total noncash impairment charge of $252,382 in the first quarter, primarily allocated to definite-lived intangible assets, which is presented as “Impairment of long-lived assets” on the condensed consolidated statements of operations.

The Company sponsors several defined benefit pension plans covering some of its employees. Certain employee groups 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 2,849,002 shares of common stock to this separate trust with an aggregate contribution value of approximately $40,000 on the contribution date. As a result of the contribution, the Company expects the approximately $58,000 required cash contribution for the fiscal year ending March 31, 2022, to be reduced to approximately $18,000.

In addition to the defined benefit pension plans, the Company provides certain healthcare ~~and life insurance~~ benefits for eligible retired employees. Such benefits are unfunded. ~~Employees achieve eligibility to participate in these contributory plans upon retirement from~~No active ~~service if they meet specified age and years of service requirements. Election to participate for some~~ employees ~~must be made at the date of retirement. Qualifying dependents at the date of retirement may also be~~are eligible for these benefits. The vast majority of eligible retirees receive a fixed-dollar benefit they can use to purchase healthcare services. A handful of eligible retirees receive traditional retiree medical ~~coverage.~~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. From time to time, changes have been made to the benefits provided to various groups of plan participants. Premiums charged to most retirees for medical coverage prior to age 65 are based on years of service and are adjusted annually for changes in the cost of the plans as determined by an independent actuary. In addition to this medical inflation cost-sharing feature, the plans also have provisions for deductibles, co-payments, coinsurance percentages, out-of-pocket limits, schedules of reasonable fees, preferred provider networks, coordination of benefits with other plans and a Medicare carve-out.

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 our evaluation of data from fund managers and comparable market data.

The Company reports financial performance based on the following 2 reportable segments: Systems & Support and Aerospace Structures. 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.

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.

During the three months ended ~~September 30,~~December 31, 2020 and 2019, the Company had foreign sales of ~~$96,734~~$78,440 and ~~$185,957,~~$164,832, respectively. During the ~~six~~nine months ended ~~September 30,~~December 31, 2020 and 2019, the Company had foreign sales of ~~$188,931~~$267,370 and ~~$361,297,~~$526,130, respectively.

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.

As the Company completes its restructuring plans as disclosed in Note 15, including the disposal of certain facilities, the Company may be exposed to additional costs such as environmental remediation obligations, lease termination costs, 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.

As disclosed in the Company's Form 10-K for the fiscal year ended March 31, 2020, during the fiscal years ended March 31, 2017 and 2016, the Company committed to restructuring plans involving certain of its businesses, as well as the consolidation of certain of its facilities. With the exception of certain consolidations to be completed in future years, these plans were substantially complete as of March 31, 2020. During the ~~six~~nine months ended ~~September 30,~~December 31, 2020, the Company incurred costs of ~~$4,536, $17,698,~~$5,725, $20,580, and $6,442, within Systems ~~and~~& Support, Aerospace Structures, and its corporate headquarters, respectively, for total restructuring costs of ~~$28,676~~$32,747 associated with new restructuring plans. Of the restructuring costs within Aerospace Structures, approximately $13,097 pertained to facility closures with the remainder primarily related to postemployment benefits arising from reductions in force and third-party consulting costs. The restructuring costs within Systems & Support and Corporate are primarily related to postemployment benefits arising from reductions in force and third-party consulting costs. We estimate that we will incur consolidated restructuring costs of approximately $34,000 for the fiscal year ended March 31, 2021, with costs being incurred in each of our segments for third-party consulting costs and severance, primarily related to our ~~cost-reductions, of approximately $32,000 to $34,000 for the fiscal year ended March 31, 2021.~~cost-reduction initiatives.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion should be read in conjunction with the condensed consolidated financial statements and notes thereto contained elsewhere herein.

We are a major supplier to the aerospace industry and have two reportable segments: (i) Systems & Support, whose companies’ revenues are derived from integrated solutions, including design, development and support of proprietary components, subsystems and systems, production of complex assemblies using external designs, as well as full life cycle solutions for commercial, regional and military aircraft; and (ii) Aerospace Structures, whose companies supply commercial, business, regional, and military manufacturers with large metallic and composite structures and produce close-tolerance parts primarily to customer designs and model-based definition, including a wide range of aluminum, hard metal and composite structure capabilities.

During the fiscal year ended March 31, 2020, the Company divested of a number of its assets and operations, including the sale of its manufacturing operations at its Nashville, TN, facility (the “Nashville divestiture”) and the assignment of its E-2 Jets contract with Embraer for the manufacture of structural components for their program to AeroSpace Technologies of Korea Inc. ("ASTK"). The operating results of the Nashville manufacturing operations are included in Aerospace Structures through the date of divestiture or assignment. Collectively, these transactions are referred to as the “fiscal 2020 divestitures.” The Company recognized combined net losses of $56.9 million associated with the fiscal 2020 divestitures, which are presented within loss on sale of assets and businesses, net on the condensed consolidated statements of operations included on the Company's Form 10-K for the fiscal year ended March 31, 2020, filed with the SEC on May 28, 2020.

Significant financial results for the ~~second~~third quarter of the fiscal year ending March 31, 2021, include:

The Company has committed to several plans (which were initiated in fiscal 2016) that incorporated the restructuring of certain of its businesses as well as the consolidation of certain of its facilities. As of March 31, 2020, with the exception of three pending facility closures to be completed in fiscal 2021 or 2022 and the COVID-19 pandemic related actions discussed below, the Company has substantially completed these plans. For the ~~six~~nine months ended ~~September 30,~~December 31, 2020 and 2019, the Company incurred ~~$28.7~~$32.7 million and ~~$8.7~~$13.5 million in restructuring costs, respectively.

In March 2020, in response to anticipated head winds resulting from the impact of COVID-19 on the aerospace industry, including the impact on global air travel, we implemented certain cost-reduction actions to improve our financial health, align capacity with expected demand, and ensure our long term competitiveness. This has included, amongst others, the reduction of indirect staff and temporary workers, reduction of overtime and the selective implementation of furloughs across our business to reduce costs while delivering on customer commitments. The actions taken to reduce headcount and reduce base pay are estimated to result in approximately $85.0 million of savings for fiscal 2021, net of severance costs. We are also reducing discretionary spending as well as reducing or deferring research and development and capital expenditures. In March 2020, we also suspended the declaration and/or payment of dividends until further notice. When combined with reductions in travel, corporate events, and other expenses, Triumph expects savings to operating cash flows of approximately $120.0 million in fiscal 2021, which does not reflect the restructuring charges described above. While, as of ~~September 30,~~December 31, 2020, we remain on track to realize the estimated $120.0 million in fiscal 2021 operating cash flow savings, there can be no assurance that we will achieve such savings in the anticipated amounts and timeline. Unrelated to COVID-19, the Company currently expects certain material cash outflows related to the completion of certain previously announced consolidation and shutdown costs with sunsetting programs and certain increased working capital outflows, both within Aerospace Structures.

While the long-term outlook for the aerospace industry remains positive due to the fundamental drivers of air travel demand, current expectations are that it will take 3-4 years for travel to return to calendar 2019 levels and a few years beyond that for the industry to return to long-term trend growth, although there can be no assurance that such period will not be longer. To balance the supply and demand given the COVID-19 shock and to preserve long-term potential and competitiveness, our customers have decided to reduce the production rates of several of their commercial aircraft programs. These rate decisions were based on assessments of the demand environment. There is significant uncertainty with respect to when commercial air traffic levels will begin to recover, and whether and at what point capacity will return to and/or exceed pre-COVID-19 levels. The Company will work with its customers to closely monitor the key factors that affect backlog and future demand, including customers’ evolving manufacturing plans, the widebody replacement cycle and the cargo market, but such impact could be material and make it difficult to compare periods.

The Company expects COVID-19 to reduce demand for commercial aviation aftermarket due to the recent sharp decreases in ~~flights;~~flights, as well as reduce demand for commercial aviation production as OEMs have lowered their related delivery rate assumptions.

The COVID-19-related reduction in OEM production rates may result in additional costs to produce and deliver our products, which

may not be mitigated through our cost-reduction initiatives and could negatively impact earnings and cash flows, particularly with respect to our fixed-price contracts.

The Company is unable at this time to reasonably estimate potential future additional financial impacts or a range of loss, if any, due to continued uncertainties related to the impacts of COVID-19 on our operations, supply chain and customers, future changes to OEM production rates, supply chain impacts, and/or the results of negotiations with particular customers. Any such impacts, including any changes in our estimates, could have a material adverse effect on our financial position, results of operations, and/or cash flows.

For example, the Company expects that, in the event that its customers are unable to resume aircraft deliveries consistent with provided assumptions, the continued absence of revenue, earnings, and cash flows associated with those deliveries would continue to have a material impact on our operating results. In the event that future OEM production rate increases occur at a slower rate or take longer than the Company is currently assuming, the Company expects that the growth in inventory and other cash flow impacts associated with production would decrease. However, while any prolonged delays in planned OEM production rate increases could mitigate the impact on our liquidity, it could significantly increase the overall expected costs to manufacture our products, which would reduce operating margins and/or increase abnormal production costs in the future. Additionally, the declines in global air travel are expected to result in reduced demand for MRO services and uncertainty exists related to the length of time until air travel returns to historical levels.

From fiscal 2015 to fiscal 2019, our Aerospace Structures business unit experienced operating and forward losses on its production of the Boeing 747-8 fuselage for Boeing, Gulfstream G280 wing for Israel Aerospace Industries, Ltd ("IAI") and Gulfstream G650 wing for Gulfstream. Further discussion is included below regarding the significant developments of these and other key programs.

The Boeing 737 MAX program represented approximately 5% of revenue for the fiscal year ended March 31, 2020, and approximately 3% of revenues for the nine months ended December 31, 2020. ~~The continued grounding~~During the three months ended December 31, 2020, the Federal Aviation Administration and the Agência Nacional de Aviação Civil of Brazil approved the 737 MAX has had a minimal unfavorable effect on our results to date. Boeing has recently resumed production operations and updated the delivery rate assumptions. Boeing’s assumptions include the timing and conditions of return to ~~service,~~flight which was quickly followed by Transport Canada and the ~~expected impact of COVID-19, as well as the timing of regulatory approvals that will enable~~European Union Aviation Safety Agency in January 2021. Boeing resumed 737 MAX deliveries in the three months ended December 31, 2020, delivering 27 aircraft. Conditions are expected to ~~resume.~~

improve as COVID vaccination distribution accelerates, and Boeing has projected further 737 MAX rate increases in the latter half of calendar year 2021. The International Air Transport Association has predicted a 55% increase in passengers traveling in 2021 to 2.8 billion passengers.

Boeing has predicted that revenue passenger miles will return to 2019 levels in approximately three years. Boeing has planned 737 MAX gradual rate increases to 31 per month in early calendar year 2022 with further gradual increases corresponding with market demand. In January, Boeing stated that it has approximately ~~450~~410 airplanes in inventory ~~at March 31, 2020,~~ and has ~~also~~ assumed that the ~~majority~~balance of 737 MAX airplanes produced during the grounding and included within inventory will be delivered ~~during~~by the ~~first~~close of calendar year after the resumption of deliveries, although at a slower pace than our previous assumptions due to COVID-19. The slower production and delivery rate ramp-ups reflect commercial airline industry uncertainty due to the impact of COVID-19. Based on the above assumption, Triumph expects2022. While we expect to see ~~declines~~gradual increases in 737 MAX revenue across both of ~~its operating~~our reportable segments in ~~its~~ fiscal ~~2021. A~~year 2022 based on these assumptions, a resurgence of COVID-19 that results in additional delays or shut downs could ~~further exacerbate~~degrade this expectation.

As of ~~March~~December 31, 2020, Triumph’s production on this program has ~~substantially~~ completed from its Hawthorne, California, facility, with the remaining production from its Grand Prairie, Texas, facility expected to ~~complete~~be completed in ~~late fiscal 2021.~~early to mid-fiscal 2022. Facility exit plans are underway at both locations and are expected to result in additional cost to exit of approximately ~~$20.0~~$10.0 million through mid-fiscal 2022 and result in projected cash uses.

In May 2020, the Company reached agreement to the accelerated transfer of the G280 wing program to IAI and Korean Aerospace Industries. The Company completed the final wing assembly in July 2020 and has closed its manufacturing operations at the leased Tulsa factory as of the end of October 2020.

In the first quarter of fiscal 2019, the Company reached an agreement with Gulfstream to optimize the supply chain on the Company's G650 work scope. The G650 wing box and wing completion work, which had been coproduced across three facilities at both companies, are being consolidated into Gulfstream’s facilities in Savannah, Georgia. The Company completed the manufacturing of its final wing box in July 2019. In August 2020, the Company completed the transfer of its remaining G650 wing supply chain activity and engineering services to Gulfstream. The company continues to produce G650 flaps and wing components under a separate supply agreement.

In September 2017, the Company reached an agreement with Boeing to supply the wing, vertical tail and horizontal tail structures for the new T-7 Red Hawk, originally known as the Boeing T-X, for the U.S. Air Force. In September 2018, the U.S. Air Force awarded the contract to Boeing. In fiscal 2020, the Company continued supply chain analysis in support of Boeing's preliminary design. Risks related to development and recurring productions costs are possible and could result in future forward losses.

Although none of the development or production programs noted above individually are expected to have a material impact on our net revenues, they do have the potential, either individually or in the aggregate, to materially and negatively impact our consolidated results of operations if future changes in estimates result in the need for a forward loss provision. Absent any such loss provisions, we do not anticipate that any of these programs will significantly dilute our future consolidated margins, although a prolonged impact of COVID-19 could result in changes in expectations.

In May 2020, the Company’s Board of Directors committed to a plan (i) to sell its composites manufacturing operations located in

Milledgeville, Georgia and Rayong, Thailand and (ii) to transfer the assets and certain liabilities associated with its Gulfstream

G650 wing supply chain activities. As noted above, the Company completed the transfer of its G650 wing supply chain activity and engineering services to Gulfstream in August 2020. Also in August 2020, the Company entered into a definitive agreement with the buyer of the composites manufacturing operations in Georgia and Thailand. During the ~~six~~nine months ended ~~September 30,~~December 31, 2020, the assets that are the subject of these transactions represented, in the aggregate, approximately ~~$93.1~~$116.3 million of the ~~$976.9 million~~$1.40 billion of consolidated net sales (or approximately ~~9.5%~~8.3% of consolidated net sales), entirely within Aerospace Structures. The transaction for the composites manufacturing operations are expected to close in late-fiscal 2021. As disclosed in Note 3, the Company recognized an impairment loss on the assets of the composites manufacturing operations of approximately $45.2 million.

The following includes a discussion of our consolidated and business segment results of operations. The Company's diverse structure and customer base do not provide for precise comparisons of the impact of price and volume changes to our results. However, we have disclosed the significant variances between the respective periods.

We prepare and publicly release annual audited and quarterly unaudited financial statements prepared in accordance with U.S. GAAP. In accordance with Securities and Exchange Commission (the "SEC") rules, we also disclose and discuss certain non-GAAP financial measures in our public filings and earning releases. Currently, the non-GAAP financial measures that we disclose are Adjusted EBITDA, which is our net loss before interest, income taxes, amortization of acquired contract liabilities, legal settlements, loss on divestitures, depreciation and amortization; and Adjusted EBITDAP, which is Adjusted EBITDA, before pension expense or benefit, including the effects of curtailments, settlements, and other early retirement incentives. We disclose Adjusted EBITDA on a consolidated and Adjusted EBITDAP on a consolidated and a reportable segment basis in our earnings releases, investor conference calls and filings with the SEC. The non-GAAP financial measures that we use may not be comparable to similarly titled measures reported by other companies. Also, in the future, we may disclose different non-GAAP financial measures in order to help our investors more meaningfully evaluate and compare our future results of operations with our previously reported results of operations.

We view Adjusted EBITDA and Adjusted EBITDAP as operating performance measures and, as such, we believe that the U.S. GAAP financial measure most directly comparable to such measures is net loss. In calculating Adjusted EBITDA and Adjusted EBITDAP, we exclude from net loss the financial items that we believe should be separately identified to provide additional analysis of the financial components of the day-to-day operation of our business. We have outlined below the type and scope of these exclusions and the material limitations on the use of these non-GAAP financial measures as a result of these exclusions. Adjusted EBITDA and Adjusted EBITDAP are not measurements of financial performance under U.S. GAAP and should not be considered as a measure of liquidity, as an alternative to net loss, or as an indicator of any other measure of performance derived in accordance with U.S. GAAP. Investors and potential investors in our securities should not rely on Adjusted EBITDA or Adjusted EBITDAP as a substitute for any U.S. GAAP financial measure, including net loss. In addition, we urge investors and potential investors in our securities to carefully review the reconciliation of Adjusted EBITDA and Adjusted EBITDAP to net loss set forth below, in our earnings releases, and in other filings with the SEC and to carefully review the U.S. GAAP financial information included as part of our Quarterly Reports on Form 10-Q and our Annual Reports on Form 10-K that are filed with the SEC, as well as our quarterly earnings releases, and compare the U.S. GAAP financial information with our Adjusted EBITDA and Adjusted EBITDAP.

Adjusted EBITDA and Adjusted EBITDAP are used by management to internally measure our operating and management performance and by investors as a supplemental financial measure to evaluate the performance of our business that, when viewed with our U.S. GAAP results and the accompanying reconciliation, we believe provides additional information that is useful to gain an understanding of the factors and trends affecting our business. We have spent more than 20 years expanding our product and service capabilities, partially through acquisitions of complementary businesses. Due to the expansion of our operations, which included acquisitions, our net loss has included significant charges for depreciation and amortization. Adjusted EBITDA and Adjusted EBITDAP exclude these charges and provide meaningful information about the operating performance of our business, apart from charges for depreciation and amortization. We believe the disclosure of Adjusted EBITDA and Adjusted EBITDAP helps investors meaningfully evaluate and compare our performance from quarter to quarter and from year to year. We also believe Adjusted EBITDA and Adjusted EBITDAP are measures of our ongoing operating performance because the isolation of noncash charges, such as depreciation and amortization, and nonoperating items, such as interest, income taxes, pension and other postretirement benefits, provides additional information about our cost structure and, over time, helps track our operating progress. In addition, investors, securities analysts, and others have regularly relied on Adjusted EBITDA and Adjusted EBITDAP to provide financial measures by which to compare our operating performance against that of other companies in our industry.

Set forth below are descriptions of the financial items that have been excluded from our net income to calculate Adjusted EBITDA and Adjusted EBITDAP and the material limitations associated with using these non-GAAP financial measures as compared with net loss from continuing operations:

Management compensates for the above-described limitations ofby using non-GAAP measures only to supplement our U.S. GAAP results and to provide additional information that is useful to gain an understanding of the factors and trends affecting our business.

The following table shows our Adjusted EBITDA and Adjusted EBITDAP reconciled to our net (loss) income for the indicated periods (in thousands):

Organic cost of sales adjusted for intersegment sales decreased ~~$177.5~~$136.7 million, or ~~32.2%~~28.6% with additional declines from the Nashville and G650 divestitures of ~~$62.7~~$68.8 million. Organic cost of sales decreased primarily due to the lower volumes described ~~above.~~above as well as a $10.0 million partial reversal of prior loss reserves. These decreases were partially offset by an approximately $23.7 million impairment loss recognized in cost of sales on certain rotable inventory that primarily arose as a result of customer fleet retirement announcements resulting from the COVID-19 pandemic. Organic gross margin for the three months ended ~~September 30,~~December 31, 2020, was ~~20.6%~~20.0% compared with ~~21.0%~~24.0% for the three months ended ~~September 30,~~December 31, 2019. The gross margin for the three months ended ~~September 30,~~December 31, 2020, decreased primarily as a result of the ~~changes in sales mix,~~impairment of impairment rotable inventory, as cost-reduction actions offset absorption related increases.

Gross margin for the three months ended ~~September 30,~~December 31, 2020, included net favorable cumulative catch-up adjustments on long-term contracts of ~~$10.1~~$3.7 million. The favorable cumulative catch-up adjustments to operating income included gross favorable adjustments of ~~$25.1~~$17.0 million and gross unfavorable adjustments of ~~$15.1~~$13.3 million.

Organic segment operating ~~loss~~income decreased by ~~$51.0~~$47.8 million, or ~~66.6%~~67.1%, primarily due to the decreased volumes and the impairment of rotable inventory described above, partially offset by decreased restructuring costs of $0.6 million as well as ~~increased restructuring costs of $7.5 million partially offset by~~ decreases in administrative compensation cost of ~~$6.7~~$7.1 million and intangible asset amortization expense of ~~$7.5~~$7.6 million, the latter being the result of the first quarter impairment disclosed in Note 10. The Nashville and G650 divestitures contributed ~~an immaterial amount~~approximately $4.2 million of operating income in the three months ended ~~September 30,~~December 31, 2019.

Corporate operations incurred expenses of ~~$19.7~~$58.4 million for the three months ended ~~September 30,~~December 31, 2020, as compared with ~~$14.9~~$73.8 million for the three months ended ~~September 30,~~December 31, 2019.

The decrease was primarily due to a prior year gain from curtailment of other postretirement benefits of $49.5 million, partially offset by additional expense in the prior year from pension curtailment losses and special termination benefits of $35.1 million, as well as changes in actuarial assumptions and experience.

The effective income tax rate for the three months ended ~~September 30,~~December 31, 2020, was ~~(2.5)~~(1.0)% compared with 21.0% for the three months ended ~~September 30,~~December 31, 2019.

Business Segment Performance — Three months ended ~~September 30,~~December 31, 2020, compared with three months ended ~~September 30,~~December 31, 2019

We report our financial performance based on the following two reportable segments: Systems & Support and Aerospace Structures. The Company's Chief Operating Decision Maker ("CODM") utilizes Adjusted EBITDAP as a primary measure of profitability to evaluate performance of its segments and allocate resources.

The results of operations among our reportable segments vary due to differences in competitors, customers, extent of proprietary deliverables and performance. For example, Systems & Support, which generally includes proprietary products and/or arrangements where we become the primary source or one of a few primary sources to our customers, our unique manufacturing capabilities command a higher margin. Also, OEMs are increasingly focusing on assembly activities while outsourcing more manufacturing and repair to third parties, and as a result, are less of a competitive force than in previous years. This compares towith Aerospace Structures, which generally includes long-term sole-source or preferred supplier contracts and the success of these programs provides a strong foundation for our business and positions us well for future growth on new programs and new derivatives.

Refer to Note 1 for further details regarding the operations and capabilities of each of our reportable segments.

We currently generate a majority of our revenue from clients in the commercial aerospace industry, the military, the business jet industry and the regional airline industry. Our growth and financial results are largely dependent on continued demand for our products and services from clients in these industries. If any of these industries experiences a downturn, our clients in these sectors may conduct less business with us. The loss of one or more of our major customers or an economic downturn in the commercial airline or the military and defense markets could have a material adverse effect on our business.

Cost of sales decreased due to the sales decrease noted above as well as sales mix and the results of the Company’s restructuring and cost-reduction activities. The Company also recognized a $10.0 million partial reversal of prior loss reserves. These decreases were partially offset by an approximately $23.7 million impairment loss recognized in cost of sales on certain rotable inventory that primarily arose as a result of customer fleet retirement announcements resulting from the COVID-19 pandemic. Gross margin decreased primarily as a result of the ~~changes in sales mix,~~impairment of rotable inventory, as cost-reduction actions offset absorption related ~~increases.~~increases and sales mix shifted to more profitable programs.

Operating income decreased primarily due to the decreased sales noted above as well as the impairment of rotable inventory. These decreases in operating income were partially offset by decreased administrative compensation cost of ~~$3.5~~$1.7 million and restructuring expense of ~~$4.1~~$3.6 million. The decrease in Adjusted EBITDAP year over year is due to the same factors that decreased operating ~~income.~~income with the exception of the rotable inventory asset impairment, which is excluded from Adjusted EBITDAP.

Systems & Support operating income as a percentage of segment sales decreased to ~~11.6%~~7.2% for the three months ended ~~September 30,~~December 31, 2020, as compared with ~~17.7%~~17.0% for the three months ended ~~September 30,~~December 31, 2019, due to the factors described above. ~~These same factors contributed to~~The exclusion of the ~~decrease~~rotable inventory asset impairment from Adjusted EBITDAP combined with the effect of sales mix and restructuring and cost-reduction activities described above resulted in an increase in Adjusted EBITDAP margin ~~year over year.~~to 18.0% from 17.3%.

Aerospace Structures: Aerospace Structures net sales decreased by ~~$193.8~~$206.6 million, or ~~45.9%~~56.0%, to ~~$228.8~~$162.4 million for the three months ended ~~September 30,~~December 31, 2020, from ~~$422.6~~$369.0 million for the three months ended ~~September 30,~~December 31, 2019. Organic net sales decreased by ~~$130.8~~$131.0 million, with additional declines from the Nashville and G650 divestitures of ~~$63.0~~$75.6 million. Organic net sales decreased due to the planned reductions on sunsetting programs (i.e., 747-8, G280, G550), the transitioned workscope on the E-2 Jet program, as well as the impacts of the COVID-19 pandemic and resulting production rate decreases primarily on commercial programs. Net sales for the three months ended ~~September 30,~~December 31, 2020, included ~~$11.9~~$4.6 million in total nonrecurring revenues, as compared with ~~$12.3~~$8.9 million in total nonrecurring revenues for the three months ended ~~September 30,~~December 31, 2019.

Aerospace Structures cost of sales decreased by ~~$188.2~~$178.8 million, or ~~49.0%~~57.0%, to ~~$196.1~~$134.7 million for the three months ended ~~September 30,~~December 31, 2020, from ~~$384.3~~$313.6 million for the three months ended ~~September 30,~~December 31, 2019. Organic cost of sales decreased by ~~$125.5~~$110.0 million, with an additional reduction in cost of sales from the Nashville and G650 divestitures of ~~$62.7~~$68.8 million. Organic gross margin for the three months ended ~~September 30,~~December 31, 2020, was ~~14.0%~~17.0% compared with ~~10.3%~~16.6% for the three months ended ~~September 30,~~December 31, 2019. The decrease in organic cost of sales is due to decrease in sales noted above. The gross margin included net favorable cumulative catch-up adjustments of ~~$9.1~~$4.0 million. The net favorable cumulative catch-up adjustments included gross favorable adjustments of ~~$24.2~~$17.0 million and gross unfavorable adjustments of ~~$15.0~~$13.0 million.

The Nashville and G650 divestitures contributed approximately $4.2 million of operating income in the three months ended December 31, 2019. The decrease in Adjusted EBITDAP year over year is due to the same factors that decreased operating income except for the decreased intangible asset amortization, which is excluded from Adjusted EBITDAP.

Aerospace Structures operating ~~loss~~income as a percentage of segment sales decreased to ~~(1.1)%~~2.7% for the three months ended ~~September 30,~~December 31, 2020, as compared with ~~operating income as a percentage of segment sales of 3.2%~~4.9% for the three months ended ~~September 30,~~December 31, 2019, due to the decrease in operating

Systems & Support: Systems & Support net sales decreased by ~~$172.5~~$247.3 million, or ~~25.9%~~24.6%, to ~~$494.1~~$758.2 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, from ~~$666.6~~$1,005.5 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2019. Sales decreased primarily due the impact of the COVID-19 pandemic and decreased sales volumes on commercial narrowbody and widebody programs, partially offset by increases in military platforms.

Systems & Support cost of sales decreased by ~~$109.8~~$139.2 million, or ~~23.5%~~19.8%, to ~~$358.1~~$564.7 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, from ~~$467.9~~$703.9 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2019. Gross margin for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, was ~~27.5%~~25.5% compared with ~~29.8%~~30.0% for the ~~six~~nine months ended ~~September 30,~~December 31, 2019. Cost of sales decreased due to the sales decrease noted above as well as sales mix and the results of the Company’s restructuring and cost-reduction ~~activities.~~activities as well as a $10.0 million partial reversal of prior loss reserves. These decreases were partially offset by an approximately $23.7 million impairment loss recognized in cost of sales on certain rotable inventory that primarily arose as a result of customer fleet retirement announcements resulting from the COVID-19 pandemic. Gross margin decreased primarily as a result of the changes in sales mix and the impairment of rotable inventory, as cost-reduction actions offset absorption related increases.

Systems & Support operating income decreased by ~~$51.4~~$89.8 million, or ~~48.3%~~54.8%, to ~~$55.0~~$74.0 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, from ~~$106.4~~$163.8 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2019. Operating income decreased primarily due to the decreased sales and factors affecting cost of sales noted above, partially offset by reductions in administrative compensation cost of ~~$5.2~~$6.9 million and restructuring costs of ~~$3.7~~$7.2 million. The decrease in Adjusted EBITDAP year over year is due to the same factors that decreased operating ~~income.~~income, with the exception of the rotable inventory asset impairment, which is excluded from Adjusted EBITDAP.

Systems & Support operating income as a percentage of segment sales decreased to ~~27.5%~~9.8% for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, as compared with ~~29.8%~~16.3% for the ~~six~~nine months ended ~~September 30,~~December 31, 2019, due to the factors described above. These same

factors contributed to the decrease in Adjusted EBITDAP margin to 14.9% from 16.5% year over ~~year.~~year, with the exception of the rotable inventory asset impairment, which is excluded from Adjusted EBITDAP.

Aerospace Structures: Aerospace Structures net sales decreased by ~~$355.1~~$561.7 million, or ~~42.2%~~46.4%, to ~~$486.7~~$649.1 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, from ~~$841.8~~$1,210.7 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2019. Organic net sales decreased by ~~$222.4~~$353.4 million, with additional declines from the Nashville and G650 divestitures of ~~$132.7~~$208.2 million. Organic net sales decreased due to the planned reductions on sunsetting programs (i.e., 747-8, G280, G550), the transitioned workscopes on the E-2 Jets and G650 programs, as well as the impacts of the COVID-19 pandemic and resulting production rate decreases primarily on commercial programs. Net sales for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, included ~~$33.9~~$38.5 million in total nonrecurring revenues, as compared with ~~$20.2~~$29.1 million in total nonrecurring revenues for the ~~six~~nine months ended ~~September 30,~~December 31, 2019.

Aerospace Structures cost of sales decreased by ~~$321.0~~$499.8 million, or ~~43.2%~~47.3%, to ~~$421.6~~$556.3 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, from ~~$742.6~~$1,056.1 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2019. Organic cost of sales decreased by ~~$188.6~~$298.6 million, with an additional reduction in cost of sales from the Nashville and G650 divestitures of ~~$132.4~~$201.2 million. Organic gross margin for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, was ~~13.2%~~14.3% compared with ~~13.9%~~14.7% for the ~~six~~nine months ended ~~September 30,~~December 31, 2019. The decrease in organic cost of sales is due to decrease in sales noted above. Organic gross margin decreased primarily as a result of increased product costs due to the lower sales volumes partially offset by the results of the Company’s restructuring and cost reduction activities and certain favorable customer settlements. The gross margin included net favorable cumulative catch-up adjustments of ~~$12.7~~$18.7 million. The net favorable cumulative catch-up adjustments included gross favorable adjustments of ~~$42.7~~$47.2 million and gross unfavorable adjustments of ~~$29.9~~$28.5 million. The net unfavorable cumulative catch-up adjustment for the ~~six~~nine months ended ~~September 30,~~December 31, 2019, was ~~$11.8~~$16.2 million.

Aerospace Structures operating income decreased by ~~$284.5~~$298.1 million, or ~~1098.9%~~678.6%, to an operating loss of ~~$258.6~~$254.2 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, from operating income of ~~$25.9~~$43.9 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2019. The decrease ~~to an~~in organic operating ~~loss~~income was ~~nearly all organic and~~ primarily the result of the decreases noted above as well as the $252.4 million long-lived asset impairment described above and an increase in restructuring costs of ~~$17.7~~$20.6 million partially offset by decreased administrative compensation cost of $7.3 million and intangible asset amortization expense of $18.6 million, the ~~current period~~latter being the result of the reduction in the carrying value of the long-lived ~~asset~~assets impaired in the first quarter impairment ~~charges~~as disclosed in Note 10. The Nashville and G650 divestitures contributed approximately $4.5 of ~~$252.4 million.~~ operating income in the nine months ended December 31, 2019.The decrease in Adjusted EBITDAP year over year is due to the same factors that decreased operating income except for the long-lived asset impairment charges, which are excluded from Adjusted EBITDAP.

Aerospace Structures operating loss as a percentage of segment sales decreased to ~~(53.1)~~(39.2)% for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, as compared with operating income as a percentage of segment sales of ~~3.1%~~3.6% for the ~~six~~nine months ended ~~September 30,~~December 31, 2019, due to the decrease in operating income as noted above. These same factors as noted above for the Adjusted EBITDAP contributed to the decrease in Adjusted EBITDAP margin to 3.2% from 7.5% year over year.

Our working capital needs are generally funded through our current cash and cash equivalents, cash flows from operations, and proceeds from the Securitization Facility. During the ~~six~~nine months ended ~~September 30,~~December 31, 2020, we had a net cash outflow of ~~$239.7~~$195.9 million from operating activities, a decrease of ~~$229.1~~$235.2 million, compared with a net cash ~~outflow~~inflow of ~~$10.6~~$39.3 million for the ~~six~~nine months ended ~~September 30,~~December 31, 2019. Cash flows from operations were unfavorably impacted by increased disbursements to our suppliers relative to the receipts from our customers, as we were unable to reduce volumes of our material purchases at the same rates that our sales declined from the impacts of COVID-19. Cash flows included ~~increased~~steady inventory levels and lower accounts payable. Additionally, of the ~~$52.0~~approximately $51.6 million in cash proceeds from the transfer of the assets and certain liabilities associated with the ~~G560~~G650 wing supply chain activities, approximately $39.4 million was received as of September 30, 2020, with the balance of approximately $12.6 million to be received in the third quarter as part of a net working capital settlement. Approximately $50.5$50.3 million of the cash proceeds were allocated to the settlement of existing relationships derived from operations and therefore are classified within operating cash ~~flows when received.~~flows. The remaining ~~$1.5~~$1.3 million of the cash proceeds were allocated to the productive assets transferred as part of the transaction and are classified within investing cash flows. ~~We expect cash~~Cash flows from operations began to recover ~~somewhat~~ in the second half of the fiscal year and we expect this to be maintained in the fourth fiscal quarter assuming there are no additional extended shut-downs of operations due to the pandemic. Cash flows from operations also included approximately ~~$20.0~~$30.0 million in the liquidation of prior period customer advances against current period deliveries.

In March 2020, in response to anticipated head winds resulting from the impact of COVID-19 on the aerospace industry, including the impact on global air travel, we implemented certain cost-reduction actions to improve our financial health, align capacity with expected demand, and ensure our long term competitiveness. This has included, amongst others, the reduction of indirect staff and temporary workers, reduction of overtime and the selective implementation of furloughs across our business to reduce costs while delivering on customer commitments. The actions taken to reduce headcount and reduce base pay are estimated to result in approximately $85.0 million of savings for fiscal 2021, net of severance costs. We are also reducing discretionary spending as well as reducing or deferring research and development and capital expenditures. In March 2020, we also suspended the declaration and/or payment of dividends until further notice. When combined with reductions in travel, corporate events, and other expenses, Triumph expects savings to operating cash flows of approximately $120.0 million in fiscal 2021, which does not reflect the restructuring charges described above. While, as of ~~September 30,~~December 31, 2020, we remain on track to realize the estimated $120.0 million in fiscal 2021 operating cash flow savings, there remains pandemic related operating risk in the remaining quarter of fiscal 2021. Accordingly, there can be no assurance that we will achieve such savings in the anticipated amounts and timeline. Unrelated to COVID-19, the Company currently expects certain material cash outflows related to the completion of certain previously announced consolidation and shutdown costs with sunsetting programs and certain increased working capital outflows, both within Aerospace Structures.

Cash flows used in investing activities for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, decreased ~~$6.3~~$39.3 million from the ~~six~~nine months ended ~~September 30,~~December 31, 2019. Cash flows used in investing activities for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, included cash from the sales of assets and businesses of ~~$1.5~~$2.4 million, primarily from the transfer of the G650 wing supply chain activities disclosed above, offset by capital expenditures of ~~$12.8~~$19.0 million. Cash flows ~~used in~~provided by investing activities for the ~~six~~nine months ended ~~September 30,~~December 31, 2019, included payments on a working capital true-up from the prior period sale of assets net of current period proceeds from sales of assets of $~~0.6~~50.0 million with additional investing outflows from capital expenditures of ~~$17.0~~$27.3 million.

Cash flows provided by financing activities for the ~~six~~nine months ended ~~September 30,~~December 31, 2020, were ~~$203.2~~$197.7 million, compared with cash flows used in financing activities for the ~~six~~nine months ended ~~September 30,~~December 31, 2019, of ~~$38.4~~$101.9 million. In March, the Company drew on its Credit Facility (as defined below), bringing the outstanding balance as of March 31, 2020, to $400.0 million. This was done as part of a comprehensive precautionary approach to increase the Company’s cash position and maximize its financial flexibility, in light of the current volatility in the global markets resulting from the COVID-19 pandemic. In the ~~six~~nine months ended ~~September 30,~~December 31, 2020, the following significant financing cash flow events occurred:

The remainder of financing cash flows pertain primarily to borrowings and payments under finance leases. As of ~~September 30,~~December 31, 2020, we had ~~$440.2~~$477.3 million of cash on hand and ~~$47.3~~$47.2 million was available under the Company's Receivables Securitization Facility (subject to any additional constraints arising from the balance of eligible receivables at that time) after giving effect to approximately ~~$27.7~~$27.8 million in outstanding letters of credit, all of which were accruing interest at LIBOR plus applicable basis points totaling approximately 3.50% per annum.

We have taken a number of actions to improve liquidity. We have implemented cost reduction actions as described above. We are also working with our customers and supply chain to accelerate receipts and conserve cash. The transfer of the assets and certain liabilities associated with the G650 wing supply chain activities reduced related contractual obligations by approximately $100.3 million as compared towith March 31, 2020. We are also deferring certain employer payroll tax payments pursuant to the Coronavirus Aid, Relief, and Economic Security (“CARES”) Act. We will evaluate additional programs if passed by the U.S. Government. We believe, based on an assessment of current market conditions, that cash flows from operations and borrowings under the Receivables Securitization Facility, or other sources of liquidity, will be sufficient to meet anticipated cash requirements for our current operations for at least the next 12 months. We are evaluating additional funding options from the U.S. Government via the U.S. Treasury and various Federal Reserve programs. We have in the past and expect to continue to evaluate the debt and other capital markets and may seek to consummate one or more transactions including a refinancing of a portion of our outstanding indebtedness, the issuance of equity (including convertible securities), the repurchase or redemption of outstanding indebtedness, or may otherwise seek transactions to extend debt maturities or obtain additional flexibility. Any of these transactions could impact our financial results. We may also use asset sale proceeds for one or more of these purposes to the extent we are able to do so in accordance with our outstanding agreements. These transactions could increase our total amount of secured indebtedness or be dilutive to stockholders. However, the COVID-19 crisis may constrain the debt and other capital markets and our ability to access the debt and other capital markets may be reduced. There can be no assurance that such funding sources will be available to us on terms favorable to us, if at all. In the event that the overall aviation market experiences delayed recoveries and divesture opportunities do not occur, the availability under the Receivables Securitization Facility may be fully utilized and additional funding sources may be needed. There can be no assurances if or when we will consummate any such transactions or the timing thereof.

The 2022 Notes, the 2024 Notes, the First Lien Notes, and the 2025 Notes (collectively, the "Senior Notes") are the Company's senior obligations and rank equally in right of payment with all of its other existing and future senior indebtedness and senior in right of payment to all of its existing and future subordinated indebtedness. The Senior Notes are guaranteed on a full, joint and several basis by each of the Guarantor Subsidiaries.

Pursuant to the documentation governing the Senior Notes, the Company may redeem some or all of its Senior Notes prior to their stated maturities, subject to certain limitations set forth in the indenture governing the applicable Senior Notes and, in certain cases,

subject to significant prepayment premiums. The Company is obligated to offer to repurchase the Senior Notes at specified prices as

a result of certain change-of-control events and a sale of all or substantially all of its assets. These restrictions and prohibitions are subject to certain qualifications and exceptions.

The indentures governing the Senior Notes, as well as the Receivables Securitization Facility, contain covenants and restrictions 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 or investments; (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 (in the case of the Senior Notes); and (viii) enter into transactions with affiliates. The Company is currently in compliance with all covenants under its debt documents.

The only consolidated subsidiaries of the Company that are not guarantors of the 2022 Notes, the 2024 Notes, the First Lien Notes, and the 2025 Notes (the "Non-Guarantor Subsidiaries") are: (i) the receivables securitization special purpose entity, and (ii) the foreign operating subsidiaries.

The First Lien Notes, and the guarantees are thereon are secured, subject to permitted liens, by first-priority liens on the Collateral, and the 2024 Notes and the guarantees thereon are secured, subject to permitted liens, by second-priority liens on the Collateral. The 2024 Notes, the First Lien Notes, and the guarantees thereon are not secured by the assets of Non-Guarantor Subsidiaries. Some of the Company’s assets are excluded from the Collateral.

The following tables present summarized financial information of the Company and the Guarantor Subsidiaries on a combined basis. The combined summarized financial information eliminates intercompany balances and transactions among the Company and the Guarantor Subsidiaries and equity in earnings and investments in any Guarantor Subsidiaries or Non-Guarantor Subsidiaries. The summarized financial information is provided in accordance with the reporting requirements of Rule 13-01 under SEC Regulation S-X for the issuer and Guarantor Subsidiaries.

In the summarized financial information above, the balances reported as of March 31, 2020, have been adjusted as compared to those reported on Form 10-K for the year ended March 31, 2020, including adjustments to conform to our current period presentation.

~~Regarding the Company’s pension plan, the~~The Company has ~~requested approval from the IRS to change~~changed the plan year for its pension plan from April 1 through March 31 (the “Existing Plan Year”) to October 1 through September 30 (the “Proposed Plan Year”). ~~If approved, the~~The change ~~will take effect on~~is effective as of October 1, ~~2020, and is expected to improve~~2020. The change in plan year improves the Plan’s funded status used in the determination of the Company’s required pension contributions. Because April 1, 2020, represented a trough for financial markets reacting to the COVID-19 pandemic, an Employee Retirement Income Security Act of 1974 (“ERISA”) funding valuation performed at this date produced a funded status that is anomalously low. The Company has projected that the impact of this black swan event can be minimized by changing the plan year to October 1, which ~~will provide~~provides a more accurate evaluation of the plan’s funded status, and ~~the Company expects that this could~~is expected to reduce required pension contributions over the next five fiscal years. Additionally, the Company has also changed the asset valuation method it uses to report the funded status of its pension plan. Refer to Note 1 for further details on this change in accounting principle.

For the fiscal year ending March 31, 2021, the Company is not required to make contributions to its U.S. defined benefit pension plan under the terms of the Employee Retirement Income Security Act of 1974 and the Pension Protection Act of 2006. Additionally, as disclosed on the Form 8-K dated December 17, 2020, the Company contributed 2,849,002 shares of common stock to Vought Aircraft Industries Inc., Master Defined Benefit Trust (the "Trust"), which is the funding vehicle for the Vought Aircraft Industries, Inc. Hourly Retirement Plan. The closing price of the Company’s common stock on the New York Stock Exchange on the date of the contribution was $14.04 per share (for an aggregate contribution value of approximately $40.0 million). This contribution is forecast to reduce the approximately $58.0 million fiscal year 2022 required cash contribution to approximately $18.0 million.

The Company's critical accounting policies are discussed in Management's Discussion and Analysis of Financial Condition and Results of Operations and notes accompanying the condensed consolidated financial statements that appear in the Annual Report on Form 10-K for the fiscal year ended March 31, 2020, and Exhibit 99.1 to the Form 8-K dated December 17, 2020. Except as otherwise disclosed in the condensed consolidated financial statements and accompanying notes included in this report, there were no material changes subsequent to the filing of the Annual Report on Form 10-K for the fiscal year ended March 31, 2020, in the Company's critical accounting policies or in the assumptions or estimates used to prepare the financial information appearing in this report.

This report contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 relating to our future operations and prospects, including statements that are based on current projections and expectations about the markets in which we operate, and our beliefs concerning future performance and capital requirements based upon current available information. Such statements are based on our beliefs as well as assumptions made by and information currently available to us. When used in this document, words like “may,” “might,” “will,” “expect,” “anticipate,” “believe,” “potential,” "plan," "estimate," and similar expressions are intended to identify forward-looking statements.
