1.  Organization, Basis of Interim Presentation and Recent Developments

Unless the context otherwise indicates or requires, as used in this Quarterly Report on Form 10-Q, references to “we,” “us,” “our,” and the “Company” refer to Spirit AeroSystems Holdings, Inc. and its consolidated subsidiaries. References to “Spirit” refer only to our subsidiary, Spirit AeroSystems, Inc., and references to “Holdings” refer only to Spirit AeroSystems Holdings, Inc.

The Company provides manufacturing and design expertise in a wide range of fuselage, propulsion, and wing products and services for aircraft original equipment manufacturers (“OEM”) and operators through its subsidiaries including Spirit. The Company's headquarters are in Wichita, Kansas, with manufacturing and assembly facilities in Tulsa, Oklahoma; Prestwick, Scotland; Wichita, Kansas; Kinston, North Carolina; Subang, Malaysia; Saint-Nazaire, France; Biddeford, Maine; Woonsocket, Rhode Island; Belfast, Northern Ireland; Casablanca, Morocco; and Dallas, Texas.

The accompanying unaudited interim condensed consolidated financial statements include the Company’s financial statements and the financial statements of its majority-owned or controlled subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the instructions to Form 10-Q and Article 10 of Regulation S-X. The Company’s fiscal quarters are 13 weeks in length. Since the Company’s fiscal year ends on December 31, the number of days in the Company’s first and fourth quarters varies slightly from year to year. All intercompany balances and transactions have been eliminated in consolidation.

As part of the monthly consolidation process, the Company’s international subsidiaries that have functional currencies other than the U.S. dollar are translated to U.S. dollars using the end-of-month translation rate for balance sheet accounts and average period currency translation rates for revenue and income accounts. The subsidiaries in Prestwick, Scotland and Subang, Malaysia use the British pound as their functional currency. All other foreign subsidiaries and branches use the U.S. dollar as their functional currency.

In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments and elimination of intercompany balances and transactions) considered necessary to fairly present the results of operations for the interim period. The results of operations for the nine months ended September 28, 2023, are not necessarily indicative of the results that may be expected for the year ending December 31, 2023.

In connection with the preparation of the condensed consolidated financial statements, the Company evaluated subsequent events through the date the financial statements were issued. The interim financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company’s 2022 Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on February 17, 2023 (the “2022 Form 10-K”).

The Company's significant accounting policies are described in Note 3 Summary of Significant Accounting Policies to our consolidated financial statements in the 2022 Form 10-K.

2.  Adoption of New Accounting Standards

In September 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) ASU No. 2022-04, Liabilities-Supplier Finance Programs (Subtopic 405-50). The amendments in the update require additional qualitative and quantitative disclosure about supplier finance programs. The guidance does not affect the recognition, measurement, or financial statement presentation of supplier finance program obligations. ASU No. 2022-04 is effective on a retrospective basis for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, except for an amended disclosure requirement related to certain rollforward information, which is effective on a prospective basis for fiscal years beginning after December 15, 2023. The adoption of this guidance did not have a significant impact on the Company's consolidated financial statements, and the Company does not expect this guidance to have a material impact prospectively.

3.  New Accounting Pronouncements

In December 2022, the FASB issued ASU No. 2022-06, which defers the sunset date of Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting from December 31, 2022 to December 31, 2024. ASU No. 2022-06 was effective upon issuance. ASU No. 2022-06 provides temporary optional guidance for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting, providing optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. To date, the Company has not had a modification to which the application of this guidance is applicable. The Company will continue evaluating the potential impact of adopting this guidance on its consolidated financial statements, the impact of which is not expected to be material.

4.  Changes in Estimates

The Company has a periodic forecasting process in which management assesses the progress and performance of the Company’s programs. This process requires management to review each program’s progress by evaluating the program schedule, changes to identified risks and opportunities, changes to estimated revenues and costs for the accounting contracts (and options if applicable), and any outstanding contract matters. Risks and opportunities include but are not limited to management’s judgment about the cost associated with the Company’s ability to achieve the schedule, technical requirements (e.g., a newly-developed product versus a mature product), and any other program requirements. Due to the span of years it may take to completely satisfy the performance obligations for the accounting contracts (and options, if any) and the scope and nature of the work required to be performed on those contracts, the estimation of total revenue and costs is subject to many variables and, accordingly, is subject to change based upon judgment. The Company’s estimate of costs depends on maintaining continuing, uninterrupted production at its manufacturing facilities and its suppliers’ facilities. The continued fragility of the global aerospace supply chain may lead to interruptions in deliveries of or increased prices for components or raw materials used in the Company's products, labor disruptions, and could delay production and/or materially adversely affect the Company's business. When adjustments in estimated total consideration or estimated total cost are required, any changes from prior estimates for fully satisfied performance obligations are recognized in the current period as a cumulative catch-up adjustment for the inception-to-date effect of such changes. Cumulative catch-up adjustments are driven by several factors including production efficiencies, assumed rate of production, the rate of overhead absorption, changes to scope of work, and contract modifications. Cumulative catch-up adjustments are primarily related to changes in the estimated margin of contracts with performance obligations that are satisfied over time.

Changes in estimates could materially adversely affect the Company’s future financial performance. While certain increases in raw material costs can generally be passed on to the Company’s customers, in most instances the Company must fully absorb cost overruns. Some of the factors that may cause the costs incurred in fulfilling contracts to vary substantially from current estimates are technical problems, production rate changes, production stoppages, materials shortages, supplier difficulties, realization targets, existence of and execution to recovery plans caused by these factors, and multiple other events, including those identified in Item 1A. “Risk Factors” of the 2022 Form 10-K. The risk particularly applies to products such as the B787, A220, and A350, which are in forward loss positions.

During the third quarter ended September 28, 2023, the Company recognized unfavorable changes in estimates of $165.1, which included net forward loss charges of $101.1, and unfavorable cumulative catch-up adjustments related to periods prior to the third quarter of 2023 of $64.0. The forward losses in the third quarter were primarily driven by labor and production cost growth on the A350 program, additional labor and supply chain cost growth on the B787 program, increased factory performance and supply chain costs on the B767 program, and production costs incurred on the Sikorsky CH-53K program. The unfavorable cumulative catch-up adjustments primarily relate to increased factory performance costs and rework costs related to the quality issue on the B737 aft pressure bulkhead on the B737 program, and production cost overruns and foreign currency movements on the A320 program.

During the third quarter ended September 29, 2022, the Company recognized unfavorable changes in estimates of $54.0, which included net forward loss charges of $49.1, and unfavorable cumulative catch-up adjustments related to periods prior to the third quarter of 2022 of $4.9. The forward losses in the quarter ended September 29, 2022 were primarily driven by losses on the A350, B787, and RB3070 programs. Increased cost estimates for production on the A350 program resulted in a forward loss reflecting additional labor, freight, and other cost requirements driven by parts shortages and production and quality issues. The B787 program forward loss was driven by increased cost estimates for supply chain, rework, and fixed cost absorption. The

RB3070 nacelle program forward loss was driven by increased engineering cost estimates. The unfavorable cumulative catch-up adjustments primarily relate to adjustments for production schedule changes and increased costs on the A320 program.

Changes in estimates are summarized below:

5.  Accounts Receivable and Allowance for Credit Losses

Accounts Receivable, net

Accounts receivable represent the Company’s unconditional rights to consideration, subject to the payment terms of the contract, for which only the passage of time is required before payment. Unbilled receivables are reflected under contract assets on the Condensed Consolidated Balance Sheets. See also Allowance for Credit Losses, below.

Accounts receivable, net consists of the following:

	September 28, 2023		December 31, 2022
Trade receivables	$	579.4	$	477.9
Other	43.8		19.7
Less: allowance for credit losses	(12.9)		(8.1)
Accounts receivable, net	$	610.3	$	489.5

The Company has agreements (through its subsidiaries) to sell, on a revolving basis, certain trade accounts receivable balances with Boeing, Airbus Group SE and its affiliates (collectively, “Airbus”), and Rolls-Royce PLC and its affiliates (collectively, “Rolls-Royce”) to third-party financial institutions. These programs were primarily entered into as a result of customers seeking payment term extensions with the Company and they continue to allow the Company to monetize the receivables prior to their payment date, subject to payment of a discount. No guarantees are delivered under the agreements. The Company's ability to continue using such agreements is primarily dependent upon the strength of the applicable customer’s financial condition. Transfers under these agreements are accounted for as sales of receivables resulting in the receivables being

(U.S. Dollars in millions other than per share amounts)

derecognized from the Company's Condensed Consolidated Balance Sheets. For the nine months ended September 28, 2023, $2,657.0 of accounts receivable were sold via these arrangements. The proceeds from these sales of receivables are included in cash from operating activities in the Condensed Consolidated Statements of Cash Flows. The recorded net loss on sale of receivables was $36.5 for the nine months ended September 28, 2023 and is included in other income and expense. See Note 21 Other Income (Expense), Net.

Allowance for Credit Losses

During the nine months ended September 28, 2023, there have been no significant changes in the factors that influenced management’s current estimate of expected credit losses, nor changes to the Company’s accounting policies or Current Expected Credit Losses methodology. The beginning balances, current period activity, and ending balances of the allocation for credit losses on accounts receivable and contract assets were not material.

6.  Contract Assets and Contract Liabilities

Contract assets primarily represent revenues recognized for performance obligations that have been satisfied but for which amounts have not been billed. Contract assets, current are those that are expected to be billed to our customer within 12 months. Contract assets, long-term are those that are expected to be billed to our customer over periods greater than 12 months. No impairments to contract assets were recorded for the period ended September 28, 2023 or the period ended September 29, 2022. See also Note 5 Accounts Receivable and Allowance for Credit Losses.

Contract liabilities are established for cash received in excess of revenues recognized and are contingent upon the satisfaction of performance obligations. Contract liabilities primarily consist of cash received on contracts for which revenue has been deferred since the receipts are in excess of transaction price resulting from the allocation of consideration based on relative standalone selling price to future units (including those under option that the Company believes are likely to be exercised) with prices that are lower than standalone selling price. These contract liabilities will be recognized earlier if the options are not fully exercised, or immediately, if the contract is terminated prior to the options being fully exercised.

	September 28, 2023		December 31, 2022		Change
Contract assets	$	616.9	$	502.2	$	114.7
Contract liabilities	(352.8)		(356.4)		3.6
Net contract assets (liabilities)	$	264.1	$	145.8	$	118.3

For the period ended September 28, 2023, the increase in contract assets reflects the net impact of more over time revenue recognition in relation to billed revenues during the period. The decrease in contract liabilities reflects the net impact of less deferred revenues recorded in excess of revenue recognized during the period. The Company recognized $66.4 of revenue that was included in the contract liability balance at the beginning of the period.

	September 29, 2022		December 31, 2021		Change
Contract assets	$	547.4	$	443.2	$	104.2
Contract liabilities	(361.7)		(387.0)		25.3
Net contract assets (liabilities)	$	185.7	$	56.2	$	129.5

For the period ended September 29, 2022, the increase in contract assets reflects the net impact of more over time revenue recognition in relation to billed revenues during the period. The decrease in contract liabilities reflects the net impact of less deferred revenues recorded in excess of revenue recognized during the period. The Company recognized $63.2 of revenue that was included in the contract liability balance at the beginning of the period.

8.  Inventory

Inventory consists of raw materials used in the production process, work-in-process, which is direct material, direct labor, overhead and purchases, and capitalized pre-production costs. Raw materials are stated at lower of cost (principally on an actual or average cost basis) or net realizable value. Capitalized pre-production costs include certain contract costs, including applicable overhead, incurred before a product is manufactured on a recurring basis. These costs are typically amortized over a period that is consistent with the satisfaction of the underlying performance obligations to which these relate.

	September 28, 2023		December 31, 2022
Raw materials	$	395.4	$	332.7
Work-in-process(1)	1,226.2		1,044.9
Finished goods	46.8		69.4
Product inventory	1,668.4		1,447.0
Capitalized pre-production	21.6		23.7
Total inventory, net	$	1,690.0	$	1,470.7

(1)Work-in-process inventory includes direct labor, direct material, overhead, and purchases on contracts for which revenue is recognized at a point in time as well as sub-assembly parts that have not been issued to production on contracts for which revenue is recognized over time using an input method. For the periods ended September 28, 2023 and December 31, 2022, work-in-process inventory includes $256.3 and $392.2, respectively, of costs incurred in anticipation of specific contracts and no impairments were recorded in the periods.

Product inventory, summarized in the table above, is shown net of valuation reserves of $148.3 and $136.8 as of September 28, 2023 and December 31, 2022, respectively.

Excess capacity and abnormal production costs are excluded from inventory and recognized as expense in the period incurred. Cost of sales for the three and nine months ended September 28, 2023 includes period expense of $56.4 and $152.9, respectively, for excess capacity production costs related to temporary B737 MAX, A320 and A220 production schedule changes, and abnormal production costs of $0.8 and $8.1, respectively, related to the temporary production pause.

9.  Property, Plant and Equipment, net

Property, plant and equipment, net consists of the following: 

 

	September 28, 2023		December 31, 2022
Land	$	30.1	$	30.1
Buildings (including improvements)	1,292.3		1,269.1
Machinery and equipment	2,439.6		2,365.1
Tooling	1,061.4		1,055.9
Capitalized software	338.3		336.1
Construction-in-progress	86.0		102.2
Total	5,247.7		5,158.5
Less: accumulated depreciation	(3,163.6)		(2,952.6)
Property, plant and equipment, net	$	2,084.1	$	2,205.9

Capitalized interest was $0.4 and $1.0 for the three months ended September 28, 2023 and September 29, 2022, respectively, and $3.8 and $2.9 for the nine months ended September 28, 2023 and September 29, 2022, respectively. Repair and maintenance costs are expensed as incurred. The Company recognized repair and maintenance costs of $32.1 and $43.7 for the three months ended September 28, 2023 and September 29, 2022, respectively, and $124.4 and $115.0 for the nine months ended September 28, 2023 and September 29, 2022, respectively.

(U.S. Dollars in millions other than per share amounts)

The Company capitalizes certain costs, such as software coding, installation, and testing, that are incurred to purchase or to create and implement internal-use computer software. Depreciation expense related to capitalized software was $5.6 and $5.0 for the three months ended September 28, 2023 and September 29, 2022, respectively, and $17.5 and $16.5 for the nine months ended September 28, 2023 and September 29, 2022, respectively.

The Company reviews capital and amortizing intangible assets (long-lived assets) for impairment on an annual basis or whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. For the period ended September 28, 2023, there were no events which would require the Company to update its impairment analysis.

10. Leases

The Company determines if an arrangement is a lease at the inception of a signed agreement. Operating leases are included in right-of-use (“ROU”) assets (long-term), short-term operating lease liabilities, and long-term operating lease liabilities on the Company’s Condensed Consolidated Balance Sheets. Finance leases are included in Property, Plant and Equipment, current maturities of long-term debt, and long-term debt.

ROU assets represent the right of the Company to use an underlying asset for the length of the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term.

To determine the present value of lease payments, the Company uses its estimated incremental borrowing rate or the implicit rate, if readily determinable. The estimated incremental borrowing rate is based on information available at the lease commencement date, including any recent debt issuances and publicly available data for instruments with similar characteristics. The ROU asset also includes any lease payments made and excludes lease incentives.

The Company's lease terms may include options to extend or terminate the lease and, when it is reasonably certain that an option will be exercised, those options are included in the net present value calculation. Leases with a term of 12 months or less, which are primarily related to automobiles and manufacturing equipment, are not recorded on the Condensed Consolidated Balance Sheets. The aggregate amount of lease cost for leases with a term of 12 months or less is not material.

The Company has lease agreements that include lease and non-lease components, which are generally accounted for separately. For certain leases (primarily related to IT equipment), the Company does account for the lease and non-lease components as a single lease component. A portfolio approach is applied to effectively account for the ROU assets and liabilities for those specific leases referenced above. The Company does not have any material leases containing variable lease payments or residual value guarantees. The Company also does not have any material subleases.

The Company currently has operating and finance leases for items such as manufacturing facilities, corporate offices, manufacturing equipment, transportation equipment, and vehicles. The majority of the Company's active leases have remaining lease terms that range between less than one year to 15 years, some of which include options to extend the leases for up to 30 years, and some of which include options to terminate the leases within one year.

Components of lease expense:

	For the Three  Months Ended				For the Nine Months Ended
	September 28, 2023		September 29, 2022		September 28, 2023		September 29, 2022

12.  Advance Payments

Advances on the B787 Program.  Boeing has made advance payments to Spirit under the B787 Special Business Provisions and General Terms Agreement (collectively, the “B787 Supply Agreement”) that are required to be repaid to Boeing by way of offset against the purchase price for future shipset deliveries. Advance repayments were initially scheduled to be spread evenly over the remainder of the first 1,000 B787 shipsets delivered to Boeing. On April 8, 2014, Spirit signed a memorandum of agreement with Boeing that suspended advance repayments related to the B787 program for a period of twelve months beginning April 1, 2014. Repayment recommenced on April 1, 2015, and any repayments that otherwise would have become due during such twelve-month period will offset the purchase price for shipsets 1001 through 1120. On December 21, 2018, Spirit signed a memorandum of agreement with Boeing that again suspended the advance repayments beginning with line unit 818. The advance repayments will resume at a lower rate of $0.45 per shipset at line number 1135 and continue through line number 1605.

In the event Boeing does not take delivery of a sufficient number of shipsets to repay the full amount of advances prior to the termination of the B787 program or the B787 Supply Agreement, any advances not then repaid will be applied against any outstanding payments then due by Boeing to us, and any remaining balance will be repaid in annual installments of $27 due on December 15th of each year until the advance payments have been fully recovered by Boeing. As of September 28, 2023, the

In an effort to minimize the disruption to Spirit's operations and its supply chain, Spirit and Boeing entered into a Memorandum of Agreement on April 12, 2019 (the “2019 MOA”), which included the terms and conditions for an advance payment to be made from Boeing to Spirit in the amount of $123.0, which was received during the third quarter of 2019. Spirit and Boeing entered into a Memorandum of Agreement on February 6, 2020, which extended the repayment date of the $123.0 advance received by Spirit under the 2019 MOA to 2022. $0.0 and $92.3 of advance payments received from Boeing were repaid in the nine months ended September 28, 2023 and September 29, 2022, respectively. There was no balance due as of September 28, 2023.

Advances on the A350 Program. During the three months ended June 29, 2023, the Company received an advance payment from Airbus of $50.0 under an agreement between Airbus S.A.S. and Spirit AeroSystems (Europe) Limited (“Spirit Europe”) signed on June 23, 2023 (the “A350 Agreement”). During the three months ended September 28, 2023, the Company received a second advance payment from Airbus of $50.0. These advances are required to be repaid along with a nominal fee to Airbus by way of offset against the purchase price of A350 FLE shipset deliveries in 2025. To the extent actual deliveries in 2025 are insufficient to offset the advance amount, any amount not offset against deliveries will be due and payable to Airbus on December 31, 2025. In connection with the A350 Agreement, Spirit Europe has pledged certain program assets including work in process inventories and raw materials at Spirit's Scotland facility in an amount sufficient to cover the advances.

Other.

13.  Fair Value Measurements

The FASB’s authoritative guidance on fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. It also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance discloses three levels of inputs that may be used to measure fair value:

Level 1 Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 1 assets and liabilities include debt and equity securities and derivative contracts that are traded in an active exchange market.

Level 2                      Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments and derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. Observable inputs, such as current and forward interest rates and foreign exchange rates, are used in determining the fair value of the interest rate swaps and foreign currency hedge contracts.

Level 3                 Unobservable inputs that are supported by little or no market activity and are significant to the fair value of assets and liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

At September 28, 2023, the Company’s long-term debt includes a senior secured term loan and senior notes described further under Note 15 Debt. The estimated fair value of the Company’s debt obligations is based on the quoted market prices for such obligations or the historical default rate for debt with similar credit ratings. The following table presents the carrying amount and estimated fair value of long-term debt. See also Note 14 Derivative and Hedging Activities and Note 16 Pension and Other Post-Retirement Benefits.

Derivatives Accounted for as Hedges

Cash Flow Hedges – Foreign Currency Forward Contract

The Company has entered into currency forward contracts, each designated as a cash flow hedge upon the date of execution, for the purpose of reducing the variability of cash flows and hedging against the foreign currency exposure for forecasted payroll, pension and vendor disbursements that are expected to be made in the British Pound Sterling. The hedging program implemented is intended to reduce foreign currency exposure, and the associated forward currency contracts hedge forecasted transactions through June 2024.

The following table summarizes the notional amounts (representing the gross contract/notional amount of the derivatives outstanding) and fair values of the derivative instruments in the Condensed Consolidated Balance Sheets as of September 28, 2023, and December 31, 2022. The foreign currency exchange contracts are measured within Level 1 of the Fair Value hierarchy. See Note 13 Fair Value Measurements.

Within the next 12 months, the Company expects to recognize a loss of ($6.3) in earnings related to the foreign currency forward contracts. As of September 28, 2023, the maximum term of the hedged forecasted transaction was 9 months. Generally, the Company has agreements with its counterparties that contain a provision whereby if the Company defaults on its existing credit facilities and payment of the loans extended under such facilities is accelerated, the Company could be declared in default under its agreements, which may result in the early termination of the outstanding derivatives governed by such agreements and the payment of an early termination amount.

Derivatives Not Accounted for as Hedges

During the nine months ended September 28, 2023, all foreign currency forward contracts were designated as hedges, and the Company applied hedge accounting to all foreign currency forward contracts.

During the nine months ended September 29, 2022, the Company entered into foreign currency forward contracts in the amount of $291.5 to minimize the risk of currency exchange rate movements on the Company's planned settlement of the repayable investment agreement between the Company and the U.K.'s Department for Business, Energy and Industrial Strategy. During the nine-month period ended September 29, 2022, these foreign currency forward contracts were settled, and new contracts were entered into in the amount of $293.7, which were also settled during the period. The Company did not designate these forward contracts as hedges or apply hedge accounting to the forward contracts. For the nine months ended September 29, 2022, the Company recorded a net gain of $1.6 to other income on the Condensed Consolidated Statements of Operations related to the foreign currency forward contracts.

(1)    In July 2022, the Company adopted and communicated to participants a plan to terminate the Company's Pension Value Plan A (“PVP A”). As further described in the Company's 2021 Form 10-K, the PVP A consists of pension plans which were frozen as of the date Holdings became a standalone company and commenced operations. During the three months ended September 29, 2022, the PVP A plan was amended, providing for an enhancement to benefits the Company is providing to certain U.S. employees in conjunction with the plan termination. The estimated liability impact of this plan amendment, $71.7, was recognized immediately as a non-cash, pre-tax non-operating charge for amortization of prior service costs.

(2) Includes a $64.6 settlement charge for the PVP A during the nine months ended September 28, 2023. Includes a $0.9 settlement charge for the PVP A during the three months ended September 29, 2022, and a ($1.4) settlement credit for PVP B related to final asset distribution in the nine months ended September 29, 2022.

The components of net periodic pension expense (income) and other benefit income, other than the service cost component, are included in Other income (expense), net in the Company's Condensed Consolidated Statements of Operations. See Note 21 Other Income (Expense), Net.

As disclosed in the Company's 2022 Form 10-K, effective October 1, 2021, the Company spun off a portion of the existing PVP A, to a new plan called PVP B (“PVP B”). As part of the PVP B plan termination process, a lump sum offering was provided during 2021 for PVP B participants and the final asset distribution was completed in the first quarter of 2022. At September 28, 2023, a pension reversion asset of $61.4 is recorded on the Restricted plan assets line item on the Company’s Condensed Consolidated Balance Sheets. Restricted plan assets are expected to be reduced over the next six years as they are

24

Spirit AeroSystems Holdings, Inc. 

Notes to the Condensed Consolidated Financial Statements (unaudited)

(U.S. Dollars in millions other than per share amounts)

distributed to employees under a qualified compensation and benefit program. Restricted plan assets are valued at fair value with gain or loss on fair value adjustments recognized within other income. The underlying investments' fair value measurement levels under the FASB's authoritative guidance on fair value measurements are Level 2, see Note 13 Fair Value Measurements.

Separately, during the nine months ended September 28, 2023, the Company received an excess plan asset reversion of $179.5 of cash from PVP A. During the nine months ended September 29, 2022, the Company withdrew $34.0 of cash from PVP B, which represented an excess plan assets reversion. These transactions were accounted for as a negative contribution and are included on the Pension plans employer contributions line item on the Condensed Consolidated Statements of Cash Flows for the nine months ended September 28, 2023 and September 29, 2022. Excise tax of $35.9 and $6.8 related to the reversion of excess plan assets was separately recorded to the Other income (expense), net line item on the Company's Condensed Consolidated Statements of Operations for the nine months ended September 28, 2023 and September 29, 2022, respectively. See also Note 21 Other Income (Expense), Net.

As disclosed in the Company's 2022 Form 10-K, in July 2022, the Company adopted and communicated to participants a plan to terminate the PVP A. During the nine months ended September 28, 2023, the Company recognized non-cash, pre-tax non-operating accounting charges of $64.6 related to the plan termination, primarily reflecting the accounting for a group annuity purchase made in the first quarter of 2023, which resulted in a settlement charge related to the accelerated recognition of the actuarial losses for the PVP A plan that were previously included in the Accumulated other comprehensive loss line item in the Stockholders' Equity section of the Company's Condensed Consolidated Balance Sheets.

In connection with the special accounting related to the termination of the PVP A plan, discussed above, a subsequent interim measurement of the Company's U.S. pension and other postretirement plan assets and obligations was completed during the three months ended September 29, 2022. The interim measurement, including the estimated impact of the plan termination liability and enhanced benefits liability noted above, prior to the current period settlement loss and amortization of prior service cost impacts included in Net Periodic Pension Expense above, was recorded to the Accumulated other comprehensive loss line item in the Stockholders' Equity section of the Company's Condensed Consolidated Balance Sheet for the period ended September 29, 2022.

Employer Contributions

Other than the reversion of excess plan assets noted above, which was accounted for as a negative contribution, the Company's expected contributions for the current year have not significantly changed from those described in the Company's 2022 Form 10-K.

17.  Stock Compensation

Holdings has established the stockholder-approved Amended and Restated 2014 Omnibus Incentive Plan (the “Omnibus Plan”), to grant cash and equity awards of Holdings' Class A Common Stock, par value $0.01 per share (the “Common Stock”), to certain individuals. Holdings has established the Long-Term Incentive Plan (the “LTIP”) under the Omnibus Plan to grant equity awards to certain employees of the Company.

The Company recognized a net total of $8.6 and $10.4 of stock compensation expense for the three months ended September 28, 2023 and September 29, 2022, respectively, and a net total of $27.8 and $28.7 of stock compensation expense for the nine months ended September 28, 2023 and September 29, 2022, respectively.

During the nine months ended September 28, 2023, 560,190 time or service-based restricted stock units (“RSUs”) were granted with an aggregate date fair values of $18.8 under the Company's LTIP. Awards vest over a three-year period, beginning on the date of grant. Values for these awards are based on the value of Common Stock on the grant date.

During the nine months ended September 28, 2023, 231,927 performance-based restricted stock units (“PBRSUs”) were granted with an aggregate grant date fair value of $12.0 under the Company’s LTIP. These awards are earned based on Holdings’ total shareholder return relative to its peer group over a three-year performance period. Values for these awards are initially measured on the grant date using the estimated payout levels derived from a Monte Carlo valuation model.

During the nine months ended September 28, 2023, 116,006 PBRSUs were granted with an aggregate grant date fair value of $4.0 under the Company’s LTIP. These awards are earned based on pre-established 2024 - 2025 free cash flow goals. Values for these awards are based on the dividend adjusted value of Common Stock on the grant date.

During the nine months ended September 28, 2023, 116,006 PBRSUs were granted with an aggregate grant date fair value of $4.0 under the Company’s LTIP. These awards are earned based on pre-established goals of revenue growth over a three-year performance period. Values for these awards are based on the dividend adjusted value of Common Stock on the grant date.

During the nine months ended September 28, 2023, 42,065 shares of restricted Common Stock and 39,005 non-employee director restricted stock units (“DRSUs”) were granted to the Board of Directors of the Company (the “Board”) with an aggregate grant date fair value of $2.0. Both types of awards vest if the non-employee director remains continuously in service for the entire one-year term to which the grant relates. If the non-employee director incurs a termination for any reason before the end of the term (before the annual meeting of stockholders following the grant), the awards are forfeited. Upon vesting, shares relating to restricted Common Stock awards are delivered to the director free of restriction; however, vested shares of Common Stock underlying DRSUs are not delivered to the director until the date that the director leaves the Board. Values for these awards are based on the value of Common Stock on the grant date.

During the nine months ended September 28, 2023, 466,597 shares of Common Stock with an aggregate grant date value of $22.5 vested under the Company's LTIP. Additionally, 41,096 shares of Common Stock previously granted to the Board vested with an aggregate grant date fair value of $1.3, and 22,155 DRSUs previously awarded to the Board vested with an aggregate grant date fair value of $0.7.

The Company maintains the Spirit AeroSystems Holdings, Inc. Employee Stock Purchase Plan (the “ESPP”) which became effective on October 1, 2017 and was amended and restated on October 21, 2022. Under the amended plan, the per-share purchase price for the Company's Common stock purchased under the ESPP is 85% of the lower of (a) the fair market value of a share on the first day of the applicable offering period or (b) the fair market value of a share on the applicable purchase date.

The Company recognized $0.9 and $1.5 of stock compensation expense related to the ESPP for the three and nine months ended September 28, 2023. The Company recognized no stock compensation expense related to the ESPP for the three and nine months ended September 29, 2022.

18. Income Taxes

The process for calculating the Company’s income tax expense involves estimating actual current taxes due plus assessing temporary differences arising from differing treatment for tax and accounting purposes that are recorded as deferred tax assets and liabilities. Deferred tax assets are periodically evaluated to determine their recoverability and whether a valuation allowance is necessary.

A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. When determining the amount of net deferred tax assets that are more likely than not to be realized, the Company assesses all available positive and negative evidence. The weight given to the positive and negative evidence is commensurate with the extent the evidence may be objectively verified. As such, it is generally difficult for positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to outweigh objective negative evidence of recent financial reporting losses.

Based on these criteria and the relative weighting of both the positive and negative evidence available, and in particular the activity surrounding our prior earnings history, including the forward losses previously recognized in the U.S., the Company has recorded a valuation allowance against U.S. deferred tax assets. Increases in the valuation allowances recorded against U.S. deferred tax assets in the nine months ended September 28, 2023 were $112.6. This is comprised of ($0.4) related to other comprehensive income (“OCI”) and $113.0 from continuing operations. As of September 28, 2023, the total net U.S. deferred tax asset before the valuation allowance was $544.9 and the total net U.S. valuation allowance was $547.7. The net U.S. deferred tax liability after valuation allowances was $2.8.

(U.S. Dollars in millions other than per share amounts)

The Company has determined a valuation allowance on certain U.K. deferred tax assets is needed based upon cumulative losses generated in the U.K. Increases in the valuation allowances recorded against U.K. deferred tax assets in the nine-month period ended September 28, 2023 were $46.9. This is comprised of $0.0 related to other comprehensive income (“OCI”) and $46.9 from continuing operations, including utilization of net operating losses. As of September 28, 2023, the total net U.K. deferred tax asset before the valuation allowance was $322.1 and the total net U.K. valuation allowance was $326.2. The net U.K. deferred tax liability after valuation allowance was $4.1.

The Company files income tax returns in all jurisdictions in which it operates. The Company establishes reserves to provide for additional income taxes that may be due upon audit. These reserves are established based on management’s assessment as to the potential exposure attributable to permanent tax adjustments and associated interest. All tax reserves are analyzed quarterly and adjustments made as events occur that warrant modification.

In general, the Company records income tax expense each quarter based on its estimate as to the full year’s effective tax rate. Certain items, however, are given discrete period treatment and the tax effects for such items are therefore reported in the quarter that an event arises. Events or items that may give rise to discrete recognition include excess tax benefits with respect to share-based compensation, finalizing amounts in income tax returns filed, finalizing audit examinations for open tax years, expiration of statutes of limitations, and changes in tax law.

The (0.16%) effective tax rate for the nine months ended September 28, 2023 differs from the (6.49%) effective tax rate for the same period of 2022 primarily due to changes in the valuation allowances recorded on U.S. and U.K. deferred tax assets, nondeductible interest expense and nondeductible excise tax. As the Company is currently reporting a pre-tax loss for the nine months ended September 28, 2023, an increase in the effective tax rate results in an increase of income tax benefits while a decrease in the rate results in a reduction of income tax benefits.

As allowed by the Coronavirus Aid, Relief, and Economic Security Act, the Company has filed a claim for a pre-tax employee retention credit of $18.8 for 2020 and $1.0 for 2021. The outstanding pre-tax employee retention credit refund claim as of September 28, 2023 is $2.2.

The Company's federal audit is conducted under the Internal Revenue Service Compliance Assurance Process (“CAP”) program and is essentially complete for the 2020 tax year. The Company will continue to participate in the CAP program for 2021 through 2023. The CAP program's objective is to resolve issues in a timely, contemporaneous manner and eliminate the need for a lengthy post-filing examination. The Company has an open tax audit in the Kingdom of Morocco for tax years ending prior to the Company's ownership of the Moroccan legal entity. There are ongoing audits in other jurisdictions that are not material to the financial statements and the Company believes appropriate provisions for all outstanding tax issues have been made for all jurisdictions and years.

On July 11, 2023, the U.K. Finance Bill 2023 Number 2, also known as the Spring Finance Bill 2023, received Royal Assent. This legislation is effective for periods beginning after December 31, 2023 and has no impact on the current financial statements.

19.  Equity

Earnings per Share Calculation

Basic net income per share is computed using the weighted-average number of outstanding shares of Common Stock during the measurement period. Diluted net income per share is computed using the weighted-average number of outstanding shares of Common Stock and, when dilutive, potential outstanding shares of Common Stock during the measurement period. Diluted earnings per share includes any dilutive impact of service-based restricted stock units, director restricted stock units, restricted stock awards, and performance-based restricted stock units.

The Company accounts for treasury stock under the cost method and includes treasury stock as a component of stockholders’ equity. As of September 28, 2023, no treasury shares have been reissued or retired.

The total authorization amount remaining under the current share repurchase program is approximately $925.0. During the nine-month period ended September 28, 2023, the Company did not repurchase any shares of its Common Stock under this

share repurchase program. Share repurchases are currently on hold. The Credit Agreement imposes restrictions on the Company’s ability to repurchase shares.

The following table sets forth the computation of basic and diluted earnings per share:

Included in the outstanding Common Stock were 0.1 million and 0.4 million of issued but unvested shares at September 28, 2023 and September 29, 2022, respectively, which are excluded from the basic Earnings Per Share (“EPS”) calculation.

Shares of Common Stock of 0.6 million and 0.7 million, respectively, were excluded from diluted EPS as a result of incurring a net loss for the three and nine months ended September 28, 2023, as the effect would have been antidilutive. Additionally, diluted EPS for the three and nine months ended September 28, 2023 excludes 0.2 million shares that may be dilutive shares of Common Stock in the future but were not included in the computation of diluted EPS because the effect was either antidilutive or the performance condition was not met.

Shares of Common Stock of 0.5 million and 0.6 million, respectively, were excluded from diluted EPS as a result of incurring a net loss for the three and nine months ended September 29, 2022, as the effect would have been antidilutive. Additionally, diluted EPS for the three and nine months ended September 29, 2022 excludes 0.3 million shares that may be dilutive shares of Common Stock in the future but were not included in the computation of diluted EPS because the effect was either antidilutive or the performance condition was not met.

Accumulated Other Comprehensive Loss

Accumulated Other Comprehensive Loss is summarized by component as follows:

20.  Commitments, Contingencies and Guarantees

Litigation

On February 10, 2020, February 24, 2020, and March 24, 2020, three separate private securities class action lawsuits were filed against the Company in the U.S. District Court for the Northern District of Oklahoma, its former Chief Executive Officer, Tom Gentile III, former Chief Financial Officer, Jose Garcia, and former Controller (principal accounting officer), John Gilson. On April 20, 2020, the Class Actions were consolidated by the court (the “Consolidated Class Action”), and on July 20, 2020, the plaintiffs filed a Consolidated Class Action Complaint which added Shawn Campbell, the Company’s former Vice President for the B737NG and B737 MAX program, as a defendant. Allegations in the Consolidated Class Action include (i) violations of Section 10(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 10b-5 promulgated thereunder against the Company and Messrs. Gentile, Garcia, and Gilson, (ii) violations of Section 20(a) of the Exchange Act against the individual defendants, and (iii) violations of Section 10(b) of the Exchange Act and Rule 10b-5(a) and (c) promulgated thereunder against all defendants.

On June 11, 2020, a shareholder derivative lawsuit (the “Derivative Action 1”) was filed against the Company (as nominal defendant), all members of the Company’s then serving Board of Directors, and Messrs. Garcia and Gilson in the U.S. District Court for the Northern District of Oklahoma. Allegations in the Derivative Action 1 include (i) breach of fiduciary duty, (ii) abuse of control, and (iii) gross mismanagement. On October 5, 2020, a shareholder derivative lawsuit (the “Derivative Action 2” and, together with Derivative Action 1, the “Derivative Actions”) was filed against the Company (as nominal defendant), all then serving members of the Company’s Board of Directors, and Messrs. Garcia and Gilson in the Eighteenth Judicial District, District Court of Sedgwick County, Kansas. Allegations in the Derivative Action 2 include (i) breach of fiduciary duty, (ii) waste of corporate assets, and (iii) unjust enrichment. The Company and the individual defendants have denied, and continue to deny, the allegations in the Derivative Actions.

The facts underlying the Consolidated Class Action and Derivative Actions relate to the accounting process compliance independent review (the “Accounting Review”) discussed in the Company’s January 30, 2020 press release and described under Management's Discussion and Analysis of Financial Condition and Results of Operations - Accounting Review in Part II, Item 7 of the Annual Report on Form 10-K for the year ended December 31, 2019, and its resulting conclusions. The Company voluntarily reported to the SEC the determination that, with respect to the third quarter of 2019, the Company did not comply with its established accounting processes related to potential third quarter contingent liabilities received after the quarter-end. On March 24, 2020, the Staff of the SEC Enforcement Division informed the Company that it had determined to close its inquiry without recommending any enforcement action against the Company. In addition, the facts underlying the Consolidated Class Action and Derivative Actions relate to the Company’s disclosures regarding the B737 MAX grounding and Spirit’s production rate (and related matters) after the grounding.

On September 18, 2020, the Company and individual defendants filed a motion to dismiss the Consolidated Class Action. That motion was granted by the U.S. District Court on January 7, 2022, which denied leave to amend and dismissed the Consolidated Class Action with prejudice. On February 4, 2022, the plaintiffs in the Consolidated Class Action appealed this

29

Spirit AeroSystems Holdings, Inc. 

Notes to the Condensed Consolidated Financial Statements (unaudited)

(U.S. Dollars in millions other than per share amounts)

decision to the Tenth Circuit Court of Appeals (the “Appellate Court”). On August 21, 2023, the Appellate Court affirmed the dismissal of the Consolidated Class Action. The Derivative Actions remain stayed at this point.

On May 3, 2023, a private securities class action lawsuit was filed in the U.S. District Court for the Southern District of New York against the Company, its former Chief Executive Officer, Tom Gentile III, and its Senior Vice President and Chief Financial Officer, Mark J. Suchinski. The lawsuit was brought on behalf of certain purchasers of securities of the Company, who allege purported misstatements and omissions concerning alleged faulty production controls and the alleged incorrect installation of fittings on certain B737 MAX planes (the “Securities Class Action”). The specific claims in the Securities Class Action include (i) violations of Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder against all defendants, and (ii) violations of Section 20(a) of the Exchange Act against the individual defendants. Lead plaintiff and counsel in the Securities Class Action were appointed on October 20, 2023. The Company believes that the claims in this lawsuit are without merit and intends to defend against them vigorously.

Spirit is also involved in litigation in the Appellate Court with its former Chief Executive Officer, Larry Lawson over Lawson's disputed violation of a restrictive covenant in his retirement and consulting agreement. On October 19, 2021, the U.S. District Court for the District of Kansas (the “District Court”) ruled in favor of Lawson and awarded him $44.8 for benefits withheld in connection with the disputed violation, as well as post-judgment interest at the rate of 4.25%. Spirit appealed the judgment to the Appellate Court. On February 27, 2023, the Appellate Court issued an opinion reversing the District Court decision and concluding that Lawson had violated the terms of the restrictive covenant and remanded for the District Court to address whether the restrictive covenant that Lawson violated was enforceable under Kansas law. On June 15, 2023, the District Court held that the restrictive covenant was enforceable as a matter of Kansas law. The District Court entered judgment in favor of Spirit on June 27, 2023. Lawson has appealed the District Court’s latest decision, and filed his opening appellate brief before the Appellate Court on October 20, 2023. Spirit will continue to defend its position vigorously on appeal. A liability for the full amount of the award issued on October 19, 2021, plus accrued interest through March 28, 2023, was recognized and remains accrued in the Condensed Consolidated Balance Sheets as of December 31, 2022 and September 28, 2023.

From time to time, in the ordinary course of business and similar to others in the industry, the Company receives requests for information from government agencies in connection with their regulatory or investigational authority. Such requests can include subpoenas or demand letters for documents to assist the government in audits or investigations. The Company reviews such requests and notices and takes appropriate action. Additionally, the Company is subject to federal and state requirements for protection of the environment, including those for disposal of hazardous waste and remediation of contaminated sites. As a result, the Company is required to participate in certain government investigations regarding environmental remediation actions.

In addition to the items addressed above, from time to time, the Company is subject to, and is presently involved in, litigation, legal proceedings, or other claims arising in the ordinary course of business. While the final outcome of these matters cannot be predicted with certainty, considering, among other things, the meritorious legal defenses available, the Company believes that, on a basis of information presently available, none of these items, when finally resolved, will have a material adverse effect on the Company’s long-term financial position or liquidity.

Customer and Vendor Claims

The Company receives, and is currently subject to, customer and vendor claims arising in the ordinary course of business, including, but not limited to, those related to product quality and late delivery. The Company accrues for matters when losses are deemed probable and reasonably estimable. In evaluating matters for accrual and disclosure purposes, the Company takes into consideration multiple factors including without limitation its historical experience with matters of a similar nature, the specific facts and circumstances asserted, the likelihood of an unfavorable outcome, and the severity of any potential loss. Any accruals deemed necessary are reevaluated at least quarterly and updated as matters progress over time.

The Company has evaluated and refined management’s original estimate of costs related to rework on the B787 aircraft, including a preliminary assessment related to rework on the forward section of the fuselage, for which the Company identified an additional fit and finish issue in the prior year. The Company continues to coordinate with Boeing to complete the necessary rework.

As described in Note 27 Subsequent Events, on October 12, 2023, the Company entered into a Memorandum of Agreement (the “MOA”) with Boeing. Among other things, the MOA includes a broad release of liability and claims through October 12, 2023, by both parties relating to Boeing's Commercial Airplanes division and its airplane programs under the General Terms Agreement for the B787 program and the General Terms Agreement for the B737, B747, B767, and B777 programs.

Contingencies

As described in Note 27 Subsequent Events, on October 12, 2023, the Company entered into the MOA with Boeing. Among other things, the MOA establishes certain recurring shipset price increases for the B787, and as a result the Company will reverse certain liabilities, including a certain amount of forward losses and material right obligation related to the B787 program in the fourth quarter of 2023.

In the third quarter of 2023, the Company updated its estimated cost to satisfy all customer firm orders on the A350 and A220 production programs. Based on forecasted backlog and rates of production, each of these programs anticipates production will extend beyond the period of time for which the Company has recorded forward losses. The Company has recorded forward losses for forecasted production on the A220 and A350 programs through the end of 2025. The Company is in active negotiations with its A220 and A350 customer, regarding, among other things, elements of price. Management has evaluated the probability that the unexercised options to complete the performance obligations for periods beyond the period of time for which it has recorded forward losses is not currently probable. While the Company does not currently believe incremental losses are evident on these programs, if negotiations with its customer do not achieve a result which eliminates or reduces the potential for incremental losses, or other strategic alternatives are abandoned, the Company believes it is reasonably possible it would record cumulative incremental losses across these programs between $0.0 and $255.0 million.

On April 12, 2023, the Company issued a notice of escapement to Boeing related to the quality issue on the B737 Vertical Fin Attach Fittings. The remediation of the quality issue requires the Company to rework B737 units within its production system and reimburse Boeing for repairs on previously delivered units in their factory and warranty costs related to units in service. As of June 29, 2023, the Company had completed the required rework on available units located at its factory in Wichita, KS. The impact to production costs is reflected within the reported total gross margins and did not materially change from the preliminary cost estimate of approximately $31.0 estimated as of March 31, 2023. Based upon informal communications to date with our customer, we believe Boeing has completed the required rework on approximately half of the affected units within its factory. The Company has not received a claim from Boeing for rework completed to date. However, the Company has made an estimate of the cost to Boeing for the units repaired to date of $23.0 for the period ended June 29, 2023. This amount is recorded as contra revenue. As described in Note 27 Subsequent Events, on October 12, 2023, the Company entered into the MOA with Boeing. Among other things, the MOA includes a broad release of liability and claims through October 12, 2023, by both parties relating to Boeing's Commercial Airplanes division and its airplane programs under the General Terms Agreement for the B787 program and the General Terms Agreement for the B737, B747, B767, and B777 programs. As a result, the Company will reverse the $23.0 contra revenue adjustment recorded in the three months ended June 29, 2023 during the three months ending December 31, 2023.

Guarantees

Contingent liabilities in the form of letters of guarantee have been provided by the Company. Outstanding guarantees were $22.8 and $13.9 at September 28, 2023 and December 31, 2022, respectively.

Restricted Cash - Collateral Requirements

The Company was required to maintain $22.2 and $19.6 of restricted cash as of September 28, 2023 and December 31, 2022, respectively, related to certain collateral requirements for obligations under its workers’ compensation programs. Restricted cash is included in Other assets in the Company's Condensed Consolidated Balance Sheets.

Indemnification

The Company has entered into customary indemnification agreements with its directors, and its bylaws and certain executive employment agreements include indemnification and advancement provisions. Pursuant to the terms of the bylaws and, with respect to Jose Garcia, his employment agreement, the Company is providing Messrs. Garcia and Gilson and all other individual defendants with defense costs and provisional indemnity with respect to the Consolidated Class Action and Derivative Actions, as well as for Mr. Gentile with regard to the Securities Class Action, as appropriate. Under the bylaws and any applicable agreements, the Company agrees to indemnify each of these individuals against claims arising out of events or occurrences related to that individual’s service as the Company’s agent or the agent of any of its subsidiaries to the fullest extent legally permitted.

The Company has agreed to indemnify parties for specified liabilities incurred, or that may be incurred, in connection with transactions they have entered into with the Company. The Company is unable to assess the potential number of future claims that may be asserted under these indemnities, nor the amounts thereof (if any). As a result, the Company cannot estimate the maximum potential amount of future payments under these indemnities and therefore, no liability has been recorded.

Service and Product Warranties and Extraordinary Rework

Provisions for estimated expenses related to service and product warranties and certain extraordinary rework are evaluated on a quarterly basis. These costs are accrued and are recorded to unallocated cost of goods sold. These estimates are established using historical information on the nature, frequency, and average cost of warranty claims, including the experience of industry peers. In the case of new development products or new customers, the Company considers other factors including the experience of other entities in the same business and management judgment, among others. Service warranty and extraordinary work is reported in current liabilities and other liabilities on the Company's Condensed Consolidated Balance Sheets.

The warranty balance presented in the table below includes unresolved warranty claims that are in dispute in regard to their value as well as their contractual liability. The Company estimated the total costs related to some of these claims; however, there is significant uncertainty surrounding the disposition of these disputed claims and as such, the ultimate determination of the provision’s adequacy requires significant management judgment. The amount of the specific provisions recorded against disputed warranty claims was $2.3 as of September 28, 2023 and December 31, 2022. These specific provisions represent the Company’s best estimate of probable warranty claims. Should the Company incur higher than expected warranty costs and/or discover new or additional information related to these warranty provisions, the Company may incur additional charges that exceed these recorded provisions. The Company utilized available information to make appropriate assessments, however the Company recognizes that data on actual claims experience is of limited duration and therefore, claims projections are subject to significant judgment. The amount of the reasonably possible disputed warranty claims in excess of the specific warranty provision was $3.4 as of September 28, 2023 and December 31, 2022.

The following is a roll forward of the service warranty and extraordinary rework balance at September 28, 2023:

Balance, December 31, 2022	$	74.9
Charges (release) to costs and expenses	0.1
Payouts	(2.2)
Exchange rate	(0.2)
Balance, September 28, 2023	$	72.6

The repayable investment obligation, which was denominated in GBP, was included on the Company’s Condensed Consolidated Balance Sheet as of December 31, 2021, as $41.7 recorded to the Other current liabilities line item and $301.9 recorded to the Other non-current liabilities line item. In January 2022, the Company made repayments of $25.6 to the UK’s Department for Business Energy and Industrial Strategy for units sold, including interest, in respect to the agreement. In April 2022, the deed of release settled the remaining outstanding repayment obligation, including current year interest accrual and foreign currency measurement impacts, in exchange for a payment of $292.8. The portion of the payments related to interest expense and the portion of the payments related to principal repayment are included in net cash used in operating activities and net cash used in financing activities, respectively, on the Company's Condensed Consolidated Statement of Cash Flows for the period ended September 29, 2022.

(5) The three and nine months ended September 29, 2022 include a gain of $10.0 related to the termination of a previously existing joint venture agreement within the period.

Included on the Company's Condensed Consolidated Balance Sheet for the nine months ended September 28, 2023 is a liability related to the customer financing of $180.0 from Boeing received in the nine months ended September 28, 2023. Per the original terms of the agreement, $90.0 of the advance was to be repaid in the first quarter of 2024 and the other $90.0 of the advance was to be repaid in 2025. Given those terms, $90.0 of the advance is included in the Other current liabilities line item and the additional $90.0 is included in the Other non-current liabilities line item as of September 28, 2023. Per the terms of the MOA signed with Boeing on October 12, 2023 (see Note 27 Subsequent Events), the repayment dates have been amended to delay the payments such that $90.0 is payable in December 2025 and the remaining $90.0 is payable in equal $45.0 installments in December 2026 and 2027.

23.  Segment Information

The Company operates in three principal segments: Commercial, Defense & Space and Aftermarket. Approximately 81% and 82% of the Company's net revenues for the three and nine months ended September 28, 2023 came from the Company's two largest customers, Boeing and Airbus. Boeing represents a substantial portion of the Company's revenues across segments. Airbus represents a substantial portion of revenues in the Commercial segment. The Company's primary profitability measure to review a segment’s operating performance is segment operating income before corporate selling, general and administrative expenses and research and development.

Corporate selling, general and administrative expenses include centralized functions such as accounting, treasury and human resources that are not specifically related to the Company's operating segments and are not allocated in measuring the operating segments’ profitability and performance and net profit margins. Research and development includes research and development efforts that benefit the Company as a whole and are not unique to a specific segment. These items are not specifically related to the Company’s operating segments and are not utilized in measuring the operating segments’ profitability and performance.

The Company’s Commercial segment includes design and manufacturing of forward, mid, and rear fuselage sections and systems, struts/pylons, nacelles (including thrust reversers) and related engine structural components, wings, and wing components (including flight control surfaces), as well as other miscellaneous structural parts for large commercial aircraft and/or business/regional jets. Sales from this segment are primarily to the aircraft OEMs or engine OEMs of large commercial aircraft and/or business/regional jet programs. Approximately 69% and 65% of Commercial segment net revenues came from the Company's contracts with Boeing for the nine months ended September 28, 2023, and September 29, 2022, respectively. Approximately 24% and 27% of Commercial segment net revenues came from the Company's contracts with Airbus for the nine months ended September 28, 2023, and September 29, 2022, respectively. The Commercial segment manufactures products at the Company's facilities in Wichita, Kansas; Tulsa, Oklahoma; Kinston, North Carolina; Prestwick, Scotland; Casablanca, Morocco; Belfast, Northern Ireland; and Subang, Malaysia.  The Commercial segment also includes an assembly plant for the A350 XWB aircraft in Saint-Nazaire, France.

The Company's Defense & Space segment includes design and manufacturing of fuselage, strut, nacelle, and wing aerostructures (primarily) for U.S. Government defense programs, including Boeing P-8, C40, and KC-46 Tanker, which are commercial aircraft that are modified for military use. The segment also includes fabrication, bonding, assembly, testing tooling, processing, engineering analysis, and training on fixed wing aircraft aerostructures, missiles and hypersonics work, including solid rocket motor throats and nozzles and re-entry vehicle thermal protections systems, forward cockpit and cabin, and fuselage work on rotorcraft aerostructures. Sales from this segment are primarily to the prime contractors on various U.S. Government defense program contracts for which the Company is a sub-contractor. A significant portion of the Company's Defense & Space segment revenues are represented by defense business that is classified by the U.S. Government and cannot be specifically described. A significant portion of Defense & Space segment net revenues came from the Company's contracts with two individual customers for the nine months ended September 28, 2023, and September 29, 2022. The Defense & Space segment manufactures products at the Company's facilities in Wichita, KS; Tulsa, OK; Biddeford, ME; Woonsocket, RI; Belfast, Northern Ireland; and Prestwick, Scotland.

The Company's Aftermarket segment includes design, manufacturing, and marketing of spare parts and maintenance, repair, and overhaul (“MRO”) services, repairs for flight control surfaces and nacelles, radome repairs, rotable assets, engineering services, advanced composite repair, and other repair and overhaul services. Approximately 47% and 47% of Aftermarket segment net revenues came from the Company's contracts with a single customer for the nine months ended September 28, 2023, and September 29, 2022, respectively. The Aftermarket segment manufactures products at the Company's facilities in Wichita, KS; Tulsa, OK; Kinston, North Carolina; Dallas, TX; Prestwick, Scotland; Casablanca, Morocco; and Belfast, Northern Ireland.

  The Company’s segments are consistent with the organization and responsibilities of management reporting to the chief operating decision-maker for the purpose of assessing performance. The Company’s definition of segment operating income differs from Operating income as presented in its primary financial statements and a reconciliation of the segment and consolidated results is provided in the table set forth below.

 While some working capital accounts are maintained on a segment basis, much of the Company’s assets are not managed or maintained on a segment basis. Property, plant, and equipment, including tooling, is used in the design and production of

34

Notes to the Condensed Consolidated Financial Statements (unaudited)

(U.S. Dollars in millions other than per share amounts)

products for each of the segments and, therefore, is not allocated to any individual segment. In addition, cash, prepaid expenses, other assets, and deferred taxes are managed and maintained on a consolidated basis and generally do not pertain to any particular segment. Raw materials and certain component parts are used in aerostructure production across all segments. Work-in-process inventory is identifiable by segment but is managed and evaluated at the program level. As there is no segmentation of the Company’s productive assets, depreciation expense (included in fixed manufacturing costs and selling, general and administrative expenses) and capital expenditures, no allocation of these amounts has been made solely for purposes of segment disclosure requirements.

The following table shows segment revenues and operating income (loss) for the nine months ended September 28, 2023 and September 29, 2022:

	Three Months Ended				Nine Months Ended

Total operating loss	$	(133.7)	$	4.5	$	(349.2)	$	(142.4)

(1) The three and nine months ended September 28, 2023 include excess capacity production costs of $54.3 and $147.0, respectively, related to the temporary B737 MAX, A320 and A220 production schedule changes, costs of $0.8 and $7.9, respectively, related to temporary production pause, and $0.0 and $6.3, respectively, of restructuring costs. The nine months ended September 29, 2022 includes the impact of $23.9 of the total charge in relation to the suspension of activities in Russia as described in Management's Discussion and Analysis of Financial Condition and Results of Operations - Global Economic Conditions and COVID-19. The three and nine months ended September 29, 2022 include $29.9 and $119.8, respectively, of excess capacity costs related to the temporary B737 MAX, A320 and A220 production schedule changes, abnormal costs of $0.3 and $9.8, respectively, of temporary workforce adjustment costs as a result of the COVID-19 pandemic, net of U.S. employee retention credit and U.K government subsidies, and net $0.0 and ($25.5), respectively, of restructuring costs and other costs, including partial offset related to the Aviation Manufacturing Jobs Protection ("AMJP") Program.

(2) The three and nine months ended September 28, 2023 include excess capacity production costs of $2.1 and $5.9 related to the temporary B737 production schedule changes, costs of $0.0 and $0.2, respectively, related to temporary production pause, and $0.0 and $0.9, respectively, of restructuring costs. The three and nine months ended September 29, 2022 include excess capacity costs of $1.5 and $6.3, respectively, related to temporary B737 production schedule changes, and $0.0 and ($2.3), respectively, of restructuring costs and partial offset related to AMJP.

(3) The three and nine months ended September 28, 2023 include $0.0 and $0.0, respectively, of restructuring costs and $0.0 and ($2.4), respectively, of benefit related to the settlement of a contingent consideration obligation related to the Applied Aerodynamics acquisition. The nine months ended September 29, 2022 includes $4.2 of the total charge in relation to the suspension of activities in Russia as described in Management's Discussion and Analysis of Financial Condition and Results of Operations - Global Economic Conditions and COVID-19. The three and nine months ended September 29, 2022 include $0.0 and ($1.9), respectively, of partial offset related to AMJP.

24.  Restructuring Costs

The Company's results of operations for the nine months ended September 28, 2023 include restructuring costs related to the Voluntary Separation Program (“VSP”) that was offered to reduce structural costs by reducing indirect headcount. Participants in the VSP received a lump sum severance payment based on their years of Company service.

Restructuring costs are presented separately as a component of operating loss on the Condensed Consolidated Statements of Operations. The total restructuring costs for the three and nine months ended September 28, 2023 were $0.0 and $7.2,

35

Spirit AeroSystems Holdings, Inc. 

Notes to the Condensed Consolidated Financial Statements (unaudited)

(U.S. Dollars in millions other than per share amounts)

respectively, of which, $6.3 was included in segment operating margins for the Commercial Segment and $0.9 was included in segment operating margins for the Defense & Space Segment.

The Company's results of operations for the nine months ended September 29, 2022 includes restructuring costs related to actions the Company has taken to align costs to updated production levels that have been directed by the Company's customers (restructuring activity). Largely beginning in the first quarter of 2020, the Company's customers, including Boeing and Airbus, significantly reduced their overall production rates as a result of the COVID-19 pandemic and, in the case of Boeing, the B737 MAX grounding. The restructuring activity materially affected the scope of operations and manner in which business is conducted by the Company compared to periods prior to the restructuring activities.

The total restructuring costs for the three and nine months ended September 29, 2022 were $0.0 and $0.2, respectively, and are included in segment operating margins for the Commercial Segment.

25. Supplier Financing

The Company has provided certain suppliers with access to a supply chain financing program through a facility with a third-party financing institution. The Company's suppliers' ability to access the program is primarily dependent upon the strength of the Company's financial condition and certain qualifying criteria. This program was primarily entered into as a result of the Company seeking payment term extensions with production suppliers, and the program allows these suppliers to monetize their receivables prior to the contractual payment date, subject to payment of a discount. The capacity of the program is limited to $97.0 at any point in time. If a supplier's request exceeds the program limit, then it will be honored when capacity is available. Under the supply chain financing program, the Company agrees to pay the third-party financing institution the stated amount of confirmed invoices from its designated suppliers on the original maturity dates of the invoices, and suppliers have the ability to be paid from the third-party financing institution on an accelerated basis. The Company’s suppliers’ election to sell one or more of the Company’s confirmed obligations under the supply chain financing program is optional. The Company's responsibility is limited to making payment on the terms originally negotiated with its suppliers for up to 120 days, regardless of whether the suppliers elect to sell their receivables to the third-party financing institution. The Company or the third-party financing institution may terminate the agreement upon at least 45 days’ notice.

The balance of confirmed obligations outstanding to suppliers who elect to participate in the supply chain financing program is included in the Company’s accounts payable balance on the Company’s Condensed Consolidated Balance Sheets. As of September 28, 2023, the balance of confirmed obligations outstanding was $112.7, an increase of $10.7 over the balance as of December 31, 2022 of $102.0. In the comparable prior year period, confirmed obligations outstanding were $103.5 as of September 29, 2022, an increase of $44.6 over the balance as of December 31, 2021. The changes in each period primarily reflect purchases from suppliers related to production levels during the respective periods.

26.  Acquisitions

T.E.A.M., Inc.

On November 23, 2022, Spirit AeroSystems Textiles, LLC, a fully owned subsidiary of Spirit AeroSystems, Inc. (“Spirit Textiles”) closed its purchase of substantially all of the assets and all of the liabilities of T.E.A.M., Inc., a Rhode Island corporation, which is engaged in the business of manufacturing and engineering textiles, composites, and textile and composite products, for cash consideration of $31.3. The acquisition was accounted for as a business combination in accordance with ASC Topic 805, Business Combinations. The purchase price has been allocated among assets acquired and liabilities assumed at fair value based on information currently available, with the excess purchase price recorded as goodwill, which is fully allocated to the Defense & Space segment. As of December 31, 2022, the Company had preliminarily concluded, but not finalized, its assessment and purchase price allocation of the acquisition. The final fair value determination was subject to a contractual post-closing working capital true-up, which the Company concluded in the three months ended March 30, 2023. The final purchase price allocation resulted in $0.6 adjustments to the assets acquired and the liabilities assumed that were recorded as of the acquisition date, which were included in the Condensed Consolidated Balance Sheet as of December 31, 2022. The adjusted assets acquired and the liabilities assumed included $8.3 of property, plant, and equipment, $1.7 of working capital, $13.5 of intangible assets and $7.7 allocated to goodwill, which is expected to be deductible for tax purposes. Operating income for the third quarter of 2023 was immaterial and reported within the Defense & Space segment.

There were no acquisition-related expenses for the nine months ended September 28, 2023. Acquisition-related expenses were $0.5 and $0.6 for the for the three and nine months ended September 29, 2022, respectively.

27. Subsequent Events

On October 12, 2023, Spirit and The Boeing Company executed the MOA to support production stability. The MOA establishes recurring shipset price increases for the B787 program effective for LN 1164 through LN 1605, recurring shipset price adjustments on the B737 program effective from the first delivery in 2026 through June 2033, releases of liabilities and claims through the effective date of the MOA by both parties relating to Boeing’s Commercial Airplanes division and its airplane programs under the General Terms Agreement for the B787 program and the General Terms Agreement for the B737, B747, B767 and B777 programs unless explicitly excluded within the MOA, Boeing provided funding for tooling and capital through 2025 for certain planned and potential B737 and B787 rate increases, amendment of repayment dates for outstanding customer financing, and changes to terms governing assignments. Regarding the tooling and capital funding, approximately $100.7 was received during the fourth quarter of 2023.

As a result of the MOA, which was executed in the fourth quarter, we expect to reverse liabilities, including previously recorded forward losses and material right obligation on the B787 program of between approximately $350.0 to $370.0 in the fourth quarter of 2023 which represents a preliminary estimate which could be subject to change based on certain performance during the fourth quarter. Regarding the $180.0 of advances received as customer financing in the quarter ended June 29, 2023, per the terms of the MOA, the repayment dates were amended. The amended repayment dates require repayment of $90.0 in December 2025 and equal payments of $45.0 in December 2026 and 2027. Additionally and separate from the range above, related to the release of claims, we will be reversing liabilities for certain claims received and other anticipated claims on our balance sheet in the fourth quarter of 2023 including the $23.0 of anticipated claims related to the Boeing 737 Vertical Fin Attach Fittings previously disclosed.

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

Unless the context otherwise indicates or requires, as used in this Quarterly Report on Form 10-Q (this “Quarterly Report”), references to “we,” “us,” “our,” and the “Company” refer to Spirit AeroSystems Holdings, Inc. and its consolidated subsidiaries. References to “Spirit” refer only to our subsidiary, Spirit AeroSystems, Inc., and references to “Holdings” refer only to Spirit AeroSystems Holdings, Inc.

International Association of Machinists and Aerospace Workers Contract Actions

As noted in our 2022 Form 10-K, as of December 31, 2022, approximately 55% of our U.S. employees were represented by the International Association of Machinists and Aerospace Workers (“IAM”) pursuant to an agreement with a then-existing expiration date of June 24, 2023. Active negotiations between the Company and the IAM Bargaining Committee began on May 1, 2023 and continued until IAM represented employees voted on the contract offer on June 21, 2023. The result of the vote was to reject the Company’s offer and to strike. In response, the Company suspended its Wichita operations impacted by IAM employees on June 22, 2023. IAM represented employees began to strike following the expiration of the contract on June 24, 2023. The Company and IAM representatives, with the assistance of a mediator from the Federal Mediation and Conciliation Service, engaged in further negotiations beginning on June 25, 2023. The result of this negotiation was a revised four-year contract offer, which was ratified by IAM represented employees on June 29, 2023. The Company began restoring operations on June 30, 2023, and fully resumed operations as the IAM workforce returned to work on July 5, 2023.

Following the vote to strike on June 22, 2023, the Company quickly implemented strategies to minimize, defer or eliminate discretionary spend, in the near term.

The IAM negotiations impacted all programs at the Wichita, Kansas site, including the B737 program. Based on current estimates of future production rates, Spirit’s labor costs will be higher than the previous IAM contract by approximately $80.0 million annually. Financial impacts through the third quarter of 2023 include strike disruption charges of $8.1 million recorded to other operating expense on the Consolidated Statements of Operations.

Global Economic Conditions and COVID-19

Global economic conditions impact our results of operations. Our business operations depend on, among other things, sufficient OEM orders (without suspension) from airlines and the financial resources of airlines, our suppliers, other companies, and individuals.

The continued fragility of the global aerospace supply chain may lead to interruptions in deliveries of or increased prices for components or raw materials used in our products, labor disruptions, and could delay production and/or materially adversely affect our business. Energy, freight, raw material, and other costs have been impacted by, and may continue to be impacted by, the war in Ukraine and the war in the Middle East. Prolonged global inflationary pressures have also impacted these costs in addition to increased interest costs and labor costs. In certain situations, we have the ability to recover certain abnormal inflationary impacts through contractual agreements with our customers; however, we anticipate that we will experience reduced levels of profitability related to inflationary impacts until such time as the rate of inflation subsides to normal historical levels. Our associated estimates of such costs, where applicable, use the most recent information available. The economic impact of inflation, together with the impact of increases in interest rates and actions taken to attempt to reduce inflation, may have a significant effect on the global economy, air travel, our supply chain, and our customers, and, as a result, on our business.

In addition, Russia’s invasion of Ukraine, the resultant sanctions and other measures imposed by the U.S. and other governments, and other related impacts have resulted in economic and political uncertainty and risks. In response to the Russian invasion of Ukraine, and the associated U.S. sanctions, the Company suspended all sanctioned activities relating to Russia, primarily consisting of sales and service activities. In the twelve months ended December 31, 2022, we recorded an aggregate pre-tax loss of $29.1 million related to adjustments of certain assets and liabilities associated with sanctioned Russian business activities. The charges are included on the Consolidated Statements of Operations for the twelve months ended December 31, 2022. The suspended activities’ impacts to prospective revenues, net income, net assets, cash flow from operations, and the Company’s Consolidated Financial Position are not material. Continuation or significant expansion of economic disruption or escalation of the conflict, or other geopolitical events of a similar nature, including the war in the Middle East, could have a material adverse effect on orders from our customers, the public’s ability or willingness to continue to travel, and/or our results of operations.

The lingering and secondary effects of the COVID-19 pandemic continue to have a significant negative impact on the aviation industry, our customers, and our business globally. Due to the uncertain nature of current conditions around the world,

38

and the capability of conditions to evolve rapidly, we are unable to predict accurately the impact that COVID-19 or similar events will have on our business going forward.

We expect that our operating environment will continue to remain dynamic and evolve through 2023. We continue to monitor and evaluate related risks and uncertainties relating to macroeconomic conditions and the COVID-19 pandemic, including the items discussed in Item 1A. “Risk Factors” in our 2022 Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on February 17, 2023 (the “2022 Form 10-K”).

B737 Program

The B737 MAX program is a critical program to the Company. For the twelve months ended December 31, 2022, 2021, and 2020 approximately 45%, 35%, and 19% of our net revenues, respectively, were generated from sales of components to Boeing for the B737 aircraft, as compared to 53% for the twelve months ended December 31, 2019, which was the most recent period to exclude impacts from the B737 MAX grounding and the COVID-19 pandemic. While we have entered into long-term supply agreements with Boeing to continue to provide components for the B737 for the life of the aircraft program, including commercial and military P-8 derivatives, Boeing does not have any obligation to purchase components from us for any replacement for the B737 that is not a commercial derivative model as defined by the Special Business Provisions and the General Terms Agreement (collectively, the “Sustaining Agreement”) between Spirit and Boeing. The Sustaining Agreement is a requirements contract and Boeing can reduce the purchase volume at any time.

In March 2019, the B737 MAX fleet was grounded in the U.S. and internationally following the 2018 and 2019 accidents involving two B737 MAX aircraft. In November 2020, the FAA issued an order rescinding the grounding of the B737 MAX and published an Airworthiness Directive specifying design changes to be made before the aircraft returned to service. Boeing’s deliveries of the B737 MAX resumed in the fourth quarter of 2020. Since November 2020, regulators from Brazil, Canada, the EU, U.K., India, and other countries have taken similar actions to unground the B737 MAX and permit return to service. Additionally, the Civil Aviation Administration of China released a report on April 14, 2023 which conveys the message that the B737 MAX has been reviewed and deliveries to carriers of new B737 MAX airplanes could resume. As of the end of September 2023, approximately 90% of China’s B737 MAX fleet spread amongst twelve Chinese carriers have resumed passenger flights.

At this time, domestic air travel demand is near 2019 levels and we expect international air travel demand to approach 2019 levels in the near future. As a result, we expect that the B737 MAX and other narrowbody production rates will recover to pre-pandemic levels before widebody production rates. We expect that air travel demand will continue to improve from 2022 levels. For additional information, see Item 1A, “Risk Factors” in the 2022 Form 10-K.

The B737 MAX 7 and MAX 10 models are currently going through Federal Aviation Administration (“FAA”) certification activities. In December 2022, an extension for certification of these two models to December 31, 2024 was granted when the U.S. Congress passed the Fiscal Year 2023 Omnibus Appropriations Bill. If Boeing is unable to achieve certification of these models or the entry into service is inconsistent with current assumptions, future revenues, earnings, and cash flows are likely to be adversely impacted.

On April 12, 2023, we issued a notice of escapement to Boeing related to the quality issue on the B737 Vertical Fin Attach Fittings. The remediation of the quality issue requires us to rework B737 units within our production system and reimburse Boeing for repairs on previously delivered units in their factory and warranty costs related to units in service. As of June 29, 2023, we have completed the required rework on available units located at our factory in Wichita, KS. The impact to production costs is reflected within the reported total gross margins and did not materially change from the preliminary cost estimate of approximately $31.0 million estimated as of March 31, 2023. Based upon informal communications to date with our customer, we believe Boeing has completed the required rework on approximately half of the affected units within its factory. We have not received a claim from Boeing for rework completed to date. However, we have made an estimate of the cost to reimburse Boeing for the units repaired to date of $23.0 million for the period ended June 29, 2023. This amount is recorded as contra revenue. As mentioned in Note 27 Subsequent Events to our condensed consolidated financial statements included in Part I of this Quarterly Report, on October 12, 2023, we entered into a Memorandum of Agreement (the “MOA”) with Boeing. Among other things, the MOA includes a broad release of liability and claims through October 12, 2023, by both parties relating to Boeing's Commercial Airplanes division and its airplane programs under the General Terms Agreement for the B787 program and the General Terms Agreement for the B737, B747, B767, and B777 programs. As a result, we will reverse the $23.0 million of contra revenue adjustment recorded in the three months ended June 29, 2023 in the three months ending December 31, 2023.

39

B787 Program

In the year ended December 31, 2020, production rate decreases from our customer on the B787 program resulted in incremental forward loss charges of $192.5 million. During the year ended December 31, 2021, the combination of further production rate decreases from our customer and estimated costs of rework and engineering changes resulted in incremental forward loss charges of $153.5 million. During the year ended December 31, 2022, our estimates for further production rate decreases and build schedule changes, supply chain costs, and other costs, including costs of rework, drove additional forward loss charges of $93.5 million. For the nine months ended September 28, 2023, our updated estimates drove an additional $93.0 million of forward loss primarily related to the impact of the IAM agreement, additional labor and supply chain cost growth. As mentioned in Note 27 Subsequent Events to our condensed consolidated financial statements included in Part I of this Quarterly Report, on October 12, 2023, we entered into the MOA with Boeing. Among other things, this MOA establishes certain recurring shipset price increases for the B787, and as a result we will reverse certain liabilities, including a certain amount of forward losses and material right obligation related to the B787 program in the three months ending December 31, 2023. Additional production rate changes, changes in cost assessments, claims, labor work stoppages, supply chain cost changes, or changes to the scope of quality issues and any associated rework, could result in an incremental loss provision.

Airbus Programs

In the year ended December 31, 2020, the A350 program recorded forward loss charges of $147.9 million associated with customer driven production rate changes. During the year ended December 31, 2021, the A350 program recorded forward loss charges of $55.2 million related to customer driven production rate changes and quality-related costs. The A350 program recorded additional forward loss charges of $105.7 million for the year ended December 31, 2022 related to estimated quality-related costs, non-recurring engineering and tooling costs, and additional labor, freight, and other cost requirements driven by parts shortages, production and quality issues, and customer production rate changes. For the nine months ended September 28, 2023, our updated estimates drove a $65.0 million incremental estimated forward loss on the A350 program, driven by the impact of schedule changes and other supply chain cost growth.

The A220 wing program recorded additional forward losses of $25 million for the year ended December 31, 2022, primarily related to the bankruptcy of a supplier and associated failure of the supplier to deliver key parts on the program. For the nine months ended September 28, 2023, our updated estimates drove a $108.3 million incremental estimated forward loss on the A220 wing program, driven by estimated supply chain costs including certain non-recurring cost estimates, schedule changes, and foreign exchange headwinds.

Critical Accounting Estimates

Goodwill

Goodwill is assessed for impairment annually on the first day of the fourth quarter, or whenever events or circumstances indicate that it is more likely than not that the estimated fair value of a reporting unit is below its carrying value.

For the year ended December 31, 2022, in accordance with our annual assessment policy, we opted to bypass the qualitative assessment and performed a quantitative assessment to test goodwill for impairment.

As part of our impairment assessment, we utilized a third-party to assist us with estimating the fair value of each of our respective reporting units under both the income approach and the market approach with equal weighing applied to the results of each approach. These approaches require making assumptions regarding long-term growth rates, revenue and earnings projections, estimation of cash flows, discount rates, and market and company-specific factors.

The results of our annual assessment indicated that the fair value substantially exceeded the carrying value for each reporting unit, and as a result, no impairment existed as of the annual assessment date during the fourth quarter of 2022. Further, we have not identified any indications of impairment that would prompt an interim impairment assessment for the quarter ended September 28, 2023.

Changes in Estimates

During the third quarter of 2023, we recognized unfavorable changes in estimates of $165.1 million, which included net forward loss charges of $101.1 million, and unfavorable cumulative catch-up adjustments related to periods prior to the third quarter of 2023 of $64.0 million. The forward losses in the third quarter were primarily driven by labor and production cost growth on the A350 program, additional labor and supply chain cost growth on the B787 program, increased factory performance and supply chain costs on the B767 program, and production costs incurred on the Sikorsky CH-53K program. The unfavorable cumulative catch-up adjustments primarily relate to increased factory performance costs and rework costs related to the quality issue on the B737 aft pressure bulkhead on the B737 program, and production cost overruns and foreign currency movements on the A320 program. As referenced above, we utilize a periodic forecasting process to assess the progress and performance of our programs. We may continue to experience forward losses in the future as a result of production schedule impacts from our customers, increases in costs related to persistent inflation, or other factors resulting in cost estimates higher than our original forecast.

During the same period in the prior year, we recognized total unfavorable changes in estimates of $54.0 million, which included net forward loss charges of $49.1 million, and unfavorable cumulative catch-up adjustments related to periods prior to the third quarter of 2022 of $4.9 million.

Three Months Ended September 28, 2023 as Compared to Three Months Ended September 29, 2022

Revenue.  Net revenue for the three months ended September 28, 2023 was $1,438.9 million, an increase of $162 million, or 12.7%, compared to net revenue of $1,276.9 million for the same period in the prior year. The increase in revenue was primarily driven by increased Boeing deliveries and increased Defense and Space revenue. Approximately 81% and 83% of Spirit’s net revenues for the third quarter of 2023 and 2022, respectively, came from our two largest customers, Boeing and Airbus.

Total deliveries to Boeing increased to 108 shipsets during the third quarter of 2023, compared to 90 shipsets delivered in the same period of the prior year, primarily driven by the continued production ramp up of the B737 program along with additional B787 deliveries. Total deliveries to Airbus decreased to 165 shipsets during the third quarter of 2023, compared to 176 shipsets delivered in the same period of the prior year, primarily driven by a decrease in A320 deliveries partially offset by additional A220 deliveries in the current quarter. Deliveries for business/regional jet components increased to 59 shipsets delivered during the third quarter of 2023, compared to 50 shipsets delivered in the same period of the prior year. In total, deliveries increased to 332 shipsets during the third quarter of 2023, compared to 316 shipsets delivered in the same period of the prior year.

Gross (Loss) Profit.  Gross loss was ($53.6) million for the three months ended September 28, 2023, compared to gross profit of $82.9 million for the same period in the prior year. The increase in loss from the prior year period was primarily driven by higher unfavorable cumulative catch-up adjustments and higher forward losses, as detailed below. In the third quarter of 2023, we recognized $56.4 million of excess capacity production costs driven by cost overruns and production schedule changes on B737 MAX, A220 and A320 programs, compared to excess capacity cost of $31.4 million in the same period of the prior year. In the third quarter of 2023, we recognized $64.0 million of unfavorable cumulative catch-up adjustments related to periods prior to the third quarter of 2023, and $101.1 million of net forward loss charges. As mentioned in the Note 4 Changes in Estimates to our condensed consolidated financial statements included in Part I of this Quarterly Report, the forward losses recorded in the third quarter of 2023 were primarily driven by labor and production cost growth on the A350 program, additional labor and supply chain cost growth on the B787 program, increased factory performance and supply chain costs on the B767 program, and production costs incurred including the impact of the IAM agreement on the Sikorsky CH-53K program. In the third quarter of 2022, we recorded $4.9 million of unfavorable cumulative catch-up adjustments related to periods prior to the third quarter of 2022, and $49.1 million of net forward loss charges primarily driven by increased cost estimates for production on the A350 program, increased engineering cost estimates on the RB3070 program, and increased cost estimates for supply chain, rework, and fixed cost absorption on the B787 program.

42

SG&A and Research and Development.  Current period SG&A was higher than in the prior year period by $0.1 million, primarily due to increased bids and proposals in Defense & Space, partially offset by reductions in incentives and purchased services. More research and development activity drove expenses $0.8 million higher for the three months ended September 28, 2023, as compared to the same period in the prior year.

Operating (Loss) Income.  Operating loss for the three months ended September 28, 2023 was ($133.7) million, a decrease of $138.2 million, compared to operating income of $4.5 million for the same period in the prior year. The variance reflects the higher unfavorable cumulative catch-up adjustments and higher forward losses detailed above.

Interest Expense and Financing Fee Amortization.  Interest expense and financing fee amortization for the three months ended September 28, 2023 increased $18.3 million compared to the same period in the prior year, driven by higher interest rates. The three months ended September 28, 2023 includes $70.1 million of interest and fees paid or accrued in connection with long-term debt and $2.9 million in amortization of deferred financing costs and original issue discount, compared to $51.3 million of interest and fees paid or accrued in connection with long-term debt and $1.9 million in amortization of deferred financing costs and original issue discount for the same period in the prior year. See also Note 15 Debt to our condensed consolidated financial statements included in Part I of this Quarterly Report.

Other Income (Expense), net. Other income, net for the three months ended September 28, 2023 was $7.3 million, compared to other expense of ($42.1) million for the same period in the prior year, a decrease in expense of $49.4 million. The decrease in other expense was primarily due to net pension related income in the current year period of $1.7 million versus net pension related expense of ($56.4) million in the prior year period. In addition, we recorded lower foreign currency gains of $12.9 million recognized in the current period, versus gains of $13.4 million in the same period of the prior year. The respective pension expense value for 2022 was driven by special accounting impacts related to pension plan termination activities. See also Note 16 Pension and Other Post-Retirement Benefits. Additionally, in the prior year period there was a gain of $10.0 million related to the termination of a joint venture agreement. See also Note 21 Other Income (Expense), Net to our condensed consolidated financial statements included in Part I of this Quarterly Report.

Provision for Income Taxes. Our reported tax rate includes two principal components: an expected annual tax rate and discrete items resulting in additional provisions or benefits that are recorded in the quarter that an event arises. Events or items that could give rise to discrete recognition include excess tax benefit in respect of share-based compensation, finalizing audit examinations for open tax years, statute of limitations expiration, or a change in tax law.

Deferred income tax assets and liabilities are recognized for future income tax consequences attributable to differences between the financial statement carrying amounts for existing assets and liabilities and their respective tax bases. A valuation allowance is recorded to reduce deferred income tax assets to an amount that in management’s opinion will ultimately be realized. We have reviewed our material deferred tax assets to determine whether or not a valuation allowance was necessary. Based on evaluation of both the positive and negative evidence available, management determined that it was necessary to continue to maintain a valuation allowance against nearly all of its net U.S. and U.K. deferred tax assets as of September 28, 2023. The net valuation allowance was increased by $43.6 million in the U.S. and by $11.2 million in the U.K. for the three months ended September 28, 2023.

The income tax provision for the three months ended September 28, 2023 includes ($6.7) million for federal taxes, $3.7 million for state taxes and $5.4 million for foreign taxes. The income tax provision for the three months ended September 29, 2022 includes $19.6 million for federal taxes, $4.3 million for state taxes and $9.0 million for foreign taxes. The effective tax rate for the three months ended September 28, 2023 is (1.19%) as compared to (34.73%) for the same period in 2022. As we are reporting a pre-tax loss for the three months ended September 28, 2023, an increase in the effective tax rate results in an increase of income tax benefits while a decrease in the rate results in a reduction of income tax benefits.

The decrease from the U.S. statutory tax rate is attributable primarily to valuation allowances on deferred tax assets.

SG&A	(69.2)		(69.1)
Research and development	(10.1)		(9.3)
Total operating loss	$	(133.7)	$	4.5

Commercial segment, Defense & Space segment, and Aftermarket segment represented approximately 79%, 14%, and 7%, respectively, of our net revenues for the three months ended September 28, 2023 and approximately 81%, 13%, and 6%, respectively, of our net revenues for the three months ended September 29, 2022.

Commercial segment.  Commercial segment net revenues for the three months ended September 28, 2023 were $1,136.4 million, an increase of $101.5 million, or 10%, compared to the same period in the prior year. The increase in revenues was primarily driven by increased deliveries to Boeing in the current period.

Commercial segment operating margins were (7%) for the three months ended September 28, 2023, compared to 4% for the same period in the prior year. The margin decreasing for the three months ended September 28, 2023, as compared to the prior year period, was primarily due to higher unfavorable changes in estimates recorded in the current period, partially offset by higher B737 deliveries. In the third quarter of 2023, the segment recorded unfavorable cumulative catch-up adjustments of $59.1 million and net forward loss charges of $86.5 million. In comparison, during the third quarter of 2022, the segment recorded unfavorable cumulative catch-up adjustments of $6.9 million and net forward loss charges of $47.4 million. For the three months ended September 28, 2023, the Commercial segment included $54.3 million of excess capacity production costs, and $0.8 million of temporary production pause charges, compared with excess capacity costs of $29.9 million, and net workforce reductions of $0.3 million, for the same period in the prior year.

Defense & Space segment. Defense & Space segment net revenues for the three months ended September 28, 2023 were $205.7 million, an increase of $44.0 million, or 27%, compared to the same period in the prior year. The variance from the prior year period includes the impact of additional revenues from progress on classified programs and increased production of the Boeing B737 program, the contracts for which include units produced for the Boeing P-8 program that are accounted for in the Defense & Space segment.

Defense & Space segment operating margins decreased to 5% for the three months ended September 28, 2023, compared to 11% for the same period in the prior year. The decrease in margin over the prior year period was primarily due to increased costs on the Boeing P-8 program resulting from higher supply chain cost estimates, as well as higher unfavorable changes in estimates recorded in the current period on the Sikorsky CH-53K program. For the three months ended September 28, 2023 the Defense & Space segment included $2.1 million of excess capacity production costs, $0.0 million of temporary production pause charges, and restructuring costs of $0.0 million, compared with compared with excess capacity costs of $1.5 million and restructuring costs of $0.0 million for the same period in the prior year. The segment recorded unfavorable cumulative catch-up adjustments of $4.9 million for the three months ended September 28, 2023. The segment recorded net forward loss charges of $14.6 million for the three months ended September 28, 2023. In comparison, during the same period of the prior year, the segment recorded favorable cumulative catch-up adjustments of $2.0 million and net forward loss charges of $1.7 million.

44

Aftermarket segment.  Aftermarket segment net revenues for the three months ended September 28, 2023 were $96.8 million, an increase of $16.5 million, or 21%, compared to the same period in the prior year. Aftermarket segment operating margins were 18% for the three months ended September 28, 2023, compared to 24% for the same period in the prior year. The decrease in margins was driven primarily by lower margins on increased activity.

Nine Months Ended September 28, 2023 as Compared to Nine Months Ended September 29, 2022

Revenue. Net revenue for the nine months ended September 28, 2023 was $4,235.0, an increase of $363.5, or 12.1%, compared to net revenue of $3,709.5 for the same period in the prior year. The increase in revenue was primarily driven by higher deliveries on Boeing and Defense programs, offset by Airbus deliveries. Approximately 82% and 82% of the Company's net revenues for the nine months ended September 28, 2023 and September 29, 2022, respectively, came from our two largest customers, Boeing and Airbus.

Total deliveries to Boeing increased to 324 shipsets during the nine months ended September 28, 2023, compared to 256 shipsets delivered in the same period of the prior year, primarily driven by the continued production ramp up of the B737 program along with additional B787 deliveries. Total deliveries to Airbus decreased to 529 shipsets during the nine months ended September 28, 2023, compared to 550 shipsets delivered in the same period of the prior year, primarily driven by customer driven schedule changes and production delays. Deliveries for business/regional jet components increased to 167 shipsets during the nine months ended September 28, 2023, compared to 149 shipsets delivered in the same period of the prior year. In total, deliveries increased to 1,020 shipsets during the nine months ended September 28, 2023, compared to 955 shipsets delivered in the same period of the prior year.

Gross (Loss) Profit. Gross loss was ($85.2) million for the nine months ended September 28, 2023, compared to gross profit of $98.1 million for the same period in the prior year. The decrease in profit over the same period of the prior year was primarily driven by higher negative changes in estimates in the current period, partially offset by higher profit on increased deliveries in B737. In the nine months ended September 28, 2023, the Company recognized $152.9 million of excess capacity production costs driven by cost overruns and production schedule changes, compared to excess capacity production costs of $126.1 million and $9.8 million of net workforce adjustments as a result of COVID-19 in the same period of the prior year. In the nine months ended September 28, 2023, the Company recognized $49.4 million of unfavorable cumulative catch-up adjustments related to periods prior to the nine months ended September 28, 2023, and $315.8 million of net forward loss charges. The forward losses recorded in the period were primarily driven by labor and production cost growth, higher supply chain costs, and schedule revisions on the A350 program and additional labor, the impact of the IAM agreement and supply chain cost growth on the B787 program, increased factory performance and supply chain costs on the B767, and production costs incurred including the impact of the IAM agreement on the Sikorsky CH-53K program. In the nine months ended September 29, 2022, the Company recorded $26.2 million of unfavorable cumulative catch-up adjustments related to periods prior to the nine months ended September 29, 2022, and $136.6 million of net forward loss charges on the B787, A350, RB3070, and A220 programs.

SG&A and Research and Development. SG&A expense was $13.4 million higher for the nine months ended September 28, 2023, compared to the same period in the prior year. The variance was driven by increases in headcount, purchased services, incentives, and travel. Less research and development activity drove research and development expense $2.6 million lower for the nine months ended September 28, 2023, as compared to the same period in the prior year.

Restructuring Costs. Restructuring costs of $7.2 million for cost alignment and headcount reductions increased $7.0 million for the nine months ended September 28, 2023, compared to the same period in the prior year. The variance is primarily driven by the results of the voluntary separation program activity in the current period.

Operating (Loss) Income. Operating loss for the nine months ended September 28, 2023 was ($349.2) million, an increase of $206.8 million, compared to the operating loss of ($142.4) million for the same period in the prior year. The increase reflects the effects of higher changes in estimates and forward loss charges as well as expenses related to the temporary production pause resulting from the IAM strike.

Interest Expense and Financing Fee Amortization. Interest expense and financing fee amortization for the nine months ended September 28, 2023 increased $50.3 million compared to the same period in the prior year, driven by higher interest rates offset by lower interest expense on the repayable investment agreement with the Department of Business, Energy, and Industrial Strategy of the Government of the United Kingdom which was fully settled in the same period of the prior year (see Note 21 Other Income (Expense), Net). The nine months ended September 28, 2023 includes $208.0 million of interest and fees paid or accrued in connection with long-term debt and $8.6 million in amortization of deferred financing costs and original issue discount, compared to $148.9 million of interest and fees paid or accrued in connection with long-term debt and $5.7 million in amortization of deferred financing costs and original issue discount for the same period in the prior year. See also Note 15 Debt to our condensed consolidated financial statements included in Part I of this Quarterly Report.

45

Other Income (Expense), net. Other expense, net for the nine months ended September 28, 2023 was ($120.0) million, compared to other income of $30.2 million for the same period in the prior year. The increase in other expense was primarily due to net pension expense of ($59.0) million in the current year period versus net pension expense of ($15.1) million in the prior year period (see Note 21 Other Income (Expense), Net to our condensed consolidated financial statements included in Part I of this Quarterly Report). In addition, we recorded ($0.4) million of foreign currency losses in the current year period versus foreign currency gains of $40.6 million in the prior year period. The increase in other expense also reflects a gain of $20.7 million recorded in the prior year period related to the settlement of the repayable investment agreement with the U.K. Department of Business, Energy and Industrial Strategy.

Provision for Income Taxes. Our reported tax rate includes two principal components: an expected annual tax rate and discrete items resulting in additional provisions or benefits that are recorded in the quarter that an event arises. Events or items that could give rise to discrete recognition include excess tax benefit in respect of share-based compensation, finalizing audit examinations for open tax years, statute of limitations expiration, or a change in tax law.

Deferred income tax assets and liabilities are recognized for future income tax consequences attributable to differences between the financial statement carrying amounts for existing asset and liabilities and their respective tax bases. A valuation allowance is recorded to reduce deferred income tax assets to an amount that in management's opinion will ultimately be realized. We have reviewed our material deferred tax assets to determine whether or not a valuation allowance was necessary. Based on evaluation of both the positive and negative evidence available, management determined that it was necessary to continue to maintain a valuation allowance against nearly all of its net U.S. and U.K. deferred tax assets as of September 28, 2023. The net valuation allowance was increased by $112.6 million in the U.S. and by $46.9 million in the U.K. for the nine months ended September 28, 2023.

The income tax provision for the nine months ended September 28, 2023 includes ($10.9) million for federal taxes, $1.1 million for state taxes and $10.9 million for foreign taxes. The income tax provision for the nine months ended September 29, 2022 includes $14.2 million for federal taxes, $2.2 million for state taxes and $2.0 million for foreign taxes. The effective tax rate for the nine months ended September 28, 2023 is (0.16%) as compared to (6.49%) for the same period in 2022. As we are reporting a pre-tax loss for the nine months ended September 28, 2023, an increase in the effective tax rate results in an increase of income tax benefits while a decrease in the rate results in a reduction of income tax benefits.

The decrease from the U.S. statutory rate is attributable primarily to nondeductible interest expense, nondeductible excise tax, valuation allowances on deferred tax assets, and foreign rate differences.

Segments. The following table shows segment revenues and operating income for the nine months ended September 28, 2023 and September 29, 2022:

Commercial segment, Defense & Space segment, and Aftermarket segment represented approximately 80%, 14%, and 7%, respectively, of our net revenues for the nine months ended September 28, 2023, and approximately 81%, 13%, and 6%, respectively, of our net revenues for the nine months ended September 29, 2022.

Commercial segment. Commercial segment net revenues for the nine months ended September 28, 2023 were $3,367.9 million, an increase of $363.5 million, or 12%, compared to the same period in the prior year. The increase in revenues was primarily driven by increased deliveries to Boeing in the current period.

Commercial segment operating margins were (6%) for the nine months ended September 28, 2023, compared to 0% for the same period in the prior year. The decrease in margin, compared to the same period in the prior year, was driven by higher unfavorable changes in estimates recorded in the period, supply chain issues and production costs on B767, A350 and A220, and the contra revenue recognized for a potential customer claim, partially offset by higher B737 deliveries and the absence of losses related to Russia sanctions recognized during the prior year period. For the nine months ended September 28, 2023, the Commercial segment includes $147.0 million of excess capacity production costs, $7.9 million of temporary production pause charges, and $6.3 million, net, of restructuring and other costs, compared with excess capacity production costs of $119.8 million, net workforce adjustments of $9.8 as a result of COVID-19, and net restructuring and other costs of ($25.5) million, including partial offset related to the AMJP Program grant of ($28.4) million for the same period in the prior year. For the nine months ended September 28, 2023, the segment recorded unfavorable cumulative catch-up adjustments of $40.7 million and net forward loss charges of $298.3 million. In comparison, for the nine months ended September 29, 2022, the segment recorded unfavorable cumulative catch-up adjustments of $27.8 million and net forward loss charges of 132.6 million. The margin for the nine months ended September 29, 2022 includes the impact of $23.9 million of the charge, mentioned above, in relation to the suspension of activities related to customers in Russia due to the Russian invasion of Ukraine, and the associated sanctions.

Defense & Space. Defense & Space segment net revenues for the nine months ended September 28, 2023 were $583.7 million, an increase of $117.1 million, or 25%, compared to the same period in the prior year. The increase from the prior year includes the impact of additional revenues from progress on classified programs and increased production on the B737 program, the contracts for which include units produced for the Boeing P-8 program that are accounted for in the Defense & Space segment.

Defense & Space segment operating margins were 7% for the nine months ended September 28, 2023, compared to 11% for the same period in the prior year. The decrease in operating income margin for the segment was primarily due to increased costs on the Boeing P-8 program resulting from the IAM union negotiations and higher supply chain cost estimates, as well as higher unfavorable changes in estimates recorded in the current period on the Sikorsky CH-53K program. For the nine months ended September 28, 2023, the Defense & Space segment includes $5.9 million of excess capacity production costs, $0.2 million of temporary production pause charges, and $0.9 million, net, of restructuring and other costs, compared with excess capacity production costs of $6.3 million and ($2.3) million of partial offset related to the AMJP Program grant during the same period of the prior year. The segment recorded unfavorable cumulative catch-up adjustments of ($8.7) million and net forward losses of ($17.5) million for the nine months ended September 28, 2023. In comparison, during the same period of the prior year, the segment recorded favorable cumulative catch-up adjustments of $1.6 million and net forward loss charges of ($4.0) million.

Aftermarket. Aftermarket segment net revenues for the nine months ended September 28, 2023 were $283.4 million, an increase of $44.9 million, or 19%, compared to the same period in the prior year. Aftermarket segment operating margins were 22% for the nine months ended September 28, 2023, compared to 21% for the same period in the prior year. For the nine months ended September 28, 2023, the margin increase reflects increases in MRO product mix and the $2.4 million benefit from the settlement of a contingent consideration obligation related to a prior year acquisition as well as the absence of losses related to Russia sanctions that were recognized in the prior year period of $4.2 million. In comparison, the operating margins for the Aftermarket segment during the nine months ended September 29, 2022 includes ($1.9) million of partial offset related to the AMJP Program grant and the impact of $4.2 million of the charge, mentioned above, in relation to the suspension of activities related to customers in Russia due to the Russian invasion of Ukraine, and the associated sanctions.

Liquidity and Capital Resources 

We assess our liquidity in terms of our ability to generate cash to fund our operating, investing, and financing activities. Our principal sources of liquidity are operating cash flows from continuing operations and borrowings to finance our business operations. During the second quarter ended June 29, 2023, our operating cash flows from continuing operations were adversely impacted by the IAM strike and the associated production pause which began on June 22, 2023 and ended on July 5, 2023. Additionally, in recent periods, other adverse impacts to our operating cash flows have been caused by, among other things, the B737 MAX grounding, the COVID-19 pandemic, production rate changes for the B737 MAX program and other programs, supply chain disruptions, labor shortages and cost increases affecting our business. We expect those adverse impacts to continue through 2023 and beyond. As discussed in Note 27 Subsequent Events to our condensed consolidated financial statements included in Part I of this Quarterly Report, on October 12, 2023, we entered into the MOA with Boeing. Among other things, the MOA includes a broad release of liability and claims through October 12, 2023, by both parties relating to Boeing's Commercial Airplanes division and its airplane programs under the General Terms Agreement for the B787 program and the General Terms Agreement for the B737, B747, B767, and B777 programs. For purposes of assessing our liquidity needs in this section, we have assumed that Boeing will not further reduce the B737 MAX production rate and that other customers generally would not further reduce their production rates. For risks that may affect that assumption, see Item 1A, “Risk Factors” in our 2022 Form 10-K.

During the quarter ended June 29, 2023, we received cash advances of $180.0 million from Boeing related to a memorandum of agreement with Boeing executed on April 28, 2023, which originally required a repayment of $90.0 million on February 14, 2024, and $90.0 million on February 14, 2025. Per the terms of the MOA signed with Boeing on October 12, 2023 (see Note 27 Subsequent Events to our condensed consolidated financial statements included in Part I of this Quarterly Report), the repayment dates have been amended to delay the payments such that $90.0 is payable in December 2025 and the remaining $90.0 is payable in equal $45.0 installments in December 2026 and 2027. Our repayment obligation will be accelerated, and any outstanding amount advanced under the agreement will immediately become due and payable, in the event that (i) we fail to make any repayment in full on the applicable Repayment Date, (ii) we fail to submit a satisfactory written confirmation that we are able to and intend to make the required repayment thirty days prior to each Repayment Date, as required under the agreement, or (iii) we repudiate any performance obligation under the agreement or certain of our existing agreements with Boeing. Boeing will have the right to set off any unpaid amount due and payable under the memorandum of agreement from any amount owed to Boeing under any other agreement between the parties. As of September 28, 2023, the $90.0 million repayable on February 14, 2024 is reflected in the Other current liabilities line item on the Condensed Consolidated Balance Sheets while the $90.0 million repayable on February 14, 2025 is reflected in the Other non-current liabilities line item. The classification of these advance liabilities will change to long-term for the entire $180.0 when the impact of the MOA is reflected in the fourth quarter of 2023. Based on the specific terms and conditions within the final agreement, the $180.0 million receipt is shown as a financing cash flow while the future repayment of the Boeing advances will be reflected as usage of financing cash flow. See Note 22 Other Liabilities to our condensed consolidated financial statements included in Part I of this Quarterly Report for more information.

During the quarters ended June 29, 2023 and September 28, 2023, we received two equal advance payments from Airbus of $50.0 million each under an agreement between Airbus S.A.S. and Spirit AeroSystems (Europe) Limited (“Spirit Europe”) signed on June 23, 2023 (the “A350 Agreement”). The A350 Agreement provides for up to $100.0 million of advances that are required to be repaid along with a nominal fee to Airbus by way of offset against the purchase price of A350 FLE shipset deliveries in 2025. To the extent actual deliveries in 2025 are insufficient to offset the advance amount, any amount not offset against deliveries will be due and payable to Airbus on December 31, 2025. Related to the A350 Agreement, Spirit Europe has pledged certain program assets including work in process inventories and raw materials at Spirit's Scotland facility in an amount sufficient to cover the advances. Based on the specific terms and conditions within the A350 Agreement, the $100.0 million of receipts are shown as operating cash flows. As the Airbus advance will be repaid through offset against shipset deliveries, those repayments will effectively reduce operating cash flow in 2025. See Note 12 Customer Advances to our condensed consolidated financial statements included in Part I of this Quarterly Report for more information.

As of September 28, 2023, our debt balance was $3,875.2 million, including $64.2 million of debt classified as short-term. As of September 28, 2023, we had $374.1 million of cash and cash equivalents on the Condensed Consolidated Balance Sheet, which reflects a decrease of $284.5 million from the cash and cash equivalents balance of $658.6 million as of December 31, 2022.

48

Based on current operating trends and the receipt of the cash advances referred to above, in addition to the impact of the MOA referenced in Note 27 Subsequent Events to our condensed consolidated financial statements included in Part I of this Quarterly Report, we believe our cash on hand and cash flows generated from operations, together with other sources of liquidity and our ability to vary our cost structure, will provide sufficient liquidity for the next twelve months and for the foreseeable future beyond the next twelve months. Beyond the next twelve months, this belief assumes that we will be able to refinance our indebtedness at or prior to maturity with new borrowings or other sources of liquidity. Limitations on our ability to access the capital or credit markets, the cost impacts of additional production rate changes or quality issues, difficulty with managing costs due to labor shortages, supply chain disruptions, inflation or other factors, or unfavorable terms or general reductions in liquidity, may adversely and materially impact our business, financial condition, and results of operations, and prevent us from being able to meet our obligations as they become due. There can be no assurance that we will be able to access the capital or credit markets or, if we do have such access, that it will be on favorable terms.

Further, we have experienced, and could continue to experience, significant fluctuations in our cash flows from period to period, particularly during the continued uncertainty in the timing of the aviation industry recovery and the current challenging macroeconomic environment. We use our cash for many activities, including operations, capital expenditures, debt service, working capital, and M&A integration activities. While we may be able to modify, defer or eliminate some of these uses to manage our cash consumption, other uses are relatively fixed and are difficult to modify in the short-term.

We have agreements to sell, on a revolving basis, certain trade accounts receivable balances with Boeing, Airbus, and Rolls-Royce to third-party financial institutions. These programs were primarily entered into as a result of Boeing and Airbus seeking payment term extensions with us, and they continue to allow us to monetize the receivables prior to their payment date, subject to payment of a discount. Our ability to continue using such agreements is primarily dependent upon the strength of Boeing’s, Airbus’s, and Rolls-Royce's financial condition. If any of these financial institutions involved with these arrangements experiences financial difficulties, becomes unwilling to support Boeing, Airbus, or Rolls-Royce due to a deterioration in their financial condition or otherwise, or is otherwise unable to honor the terms of the factoring arrangements, we may experience significant disruption and potential liquidity issues, which could have an adverse impact upon our operating results, financial condition, and cash flows. For the nine months ended September 28, 2023, $2,657.0 million of accounts receivable were sold via these arrangements.

Cash Flows

The following table provides a summary of our cash flows for the nine months ended September 28, 2023 and September 29, 2022:

	For the Nine Months Ended
	September 28, 2023		September 29, 2022
	($ in millions)
Net cash used in operating activities	$	(339.5)	$	(367.4)
Net cash used in investing activities	(76.5)		(88.8)
Net cash provided by (used in) financing activities	134.1		(334.5)
Effect of exchange rate change on cash and cash equivalents	—		(17.5)
Net decrease in cash, cash equivalents and restricted cash for the period	(281.9)		(808.2)
Cash, cash equivalents, and restricted cash beginning of period	678.4		1,498.4
Cash, cash equivalents, and restricted cash, end of period	$	396.5	$	690.2

 Nine Months Ended September 28, 2023 as Compared to Nine Months Ended September 29, 2022

Operating Activities. For the nine months ended September 28, 2023, we had a net cash outflow of $339.5 million from operating activities, a decrease in net outflow of $27.9 million compared to a net cash outflow of $367.4 million for the same period in the prior year. The decrease in net cash outflow, period over period, primarily represents the excess pension plan asset reversion to cash discussed in Note 16 Pension and Other Post-Retirement Benefits to our condensed consolidated financial statements included in Part I of this Quarterly Report as well as the receipt of $100 million of advances from customers in the current year.

49

Investing Activities. For the nine months ended September 28, 2023, we had a net cash outflow of $76.5 million for investing activities, a decrease in outflow of $12.3 million compared to a net cash outflow of $88.8 million for the same period in the prior year. The cash outflows for investing activities in both periods was driven by capital expenditures.

Financing Activities. For the nine months ended September 28, 2023, we had a net cash inflow of $134.1 million for financing activities, an increase in inflow of $468.6 million, compared to a net cash outflow of $334.5 million for the same period in the prior year. The increased cash inflow was primarily driven by the receipt of $180.0 million of advances from Boeing in the current year and the prior year $289.5 million principal repayment of the repayable investment agreement between the Company and the U.K.'s Department for Business, Energy, and Industrial Strategy. During the nine months ended September 28, 2023, we did not pay any dividends, compared to a dividend of $3.2 million paid in the same period in the prior year. There were no repurchases of Common Stock under our share repurchase program during either the nine months ended September 28, 2023 or September 29, 2022.

Pension and Other Post-Retirement Benefit Obligations

Effective October 1, 2021, we spun off a portion of the existing Pension Value Plan (“PVP A”), to a new plan called PVP B (“PVP B”). As part of the PVP B plan termination process, a lump sum offering was provided during 2021 for PVP B participants and the final asset distribution was completed in the first quarter of 2022. At September 28, 2023 and December 31, 2022, an excess pension plan asset reversion of $61.4 million and $71.1 million is recorded on the Restricted plan assets line item on the Company’s Condensed Consolidated Balance Sheets. Restricted plan assets are expected to be reduced over seven years as they are distributed to employees under a qualified benefit program.

Separately, during the nine months ended September 28, 2023, we received an excess plan asset reversion of $179.5 million of cash from PVP A. This transaction was accounted for as a negative contribution and is included on the Pension plans employer contributions line item on the Consolidated Statements of Cash Flows for the nine months ended September 28, 2023. Excise tax of $35.9 million related to the reversion of excess plan assets was separately recorded to the Other income (expense), net line item on the Consolidated Statements of Operations for the nine months ended September 28, 2023. See also Note 21 Other Income (Expense), Net to our condensed consolidated financial statements included in Part I of this Quarterly Report for more information.

As disclosed in the Company's 2022 Form 10-K, in July 2022, the Company adopted and communicated to participants a plan to terminate PVP A. In the first quarter of 2023, the Company recognized additional non-cash, pre-tax non-operating settlement accounting charges of $64.6 million related to the purchase of annuities for any participants not electing a lump-sum distribution.

Our U.S. pension plan remained fully funded at September 28, 2023. Our plan investments are broadly diversified, and we do not anticipate a near-term requirement to make cash contributions to our U.S. pension plan. See Note 16 Pension and Other Post-Retirement Benefits to our condensed consolidated financial statements included in Part I of this Quarterly Report for more information on the Company’s pension plans. Other than the reversion of excess plan assets noted above, which was accounted for as a negative contribution, the Company's expected contributions for the current year have not significantly changed from those described in the Company's 2022 Form 10-K. The Shorts’ Pension has been in a deficit position during recent years, and there is a risk that additional contributions will be required from the trustees or the U.K. Pension Regulator as described under Part I, Item 1A. “Risk Factors” of our 2022 Form 10-K.

Derivatives Accounted for as Hedges

Cash Flow Hedges – Foreign Currency Forward Contract

The Company has entered into a series of currency forward contracts, each designated as a cash flow hedge upon the date of execution, for the purpose of reducing the variability of cash flows and hedging against the foreign currency exposure for forecasted payroll, pension and vendor disbursements that are expected to be made in the British pound sterling at our operations located in Belfast, Northern Ireland. The hedging program implemented is intended to reduce foreign currency exposure, and the associated forward currency contracts hedge forecasted transactions through June 2024. Changes in the fair value of cash flow hedges are recorded in AOCI and recorded in earnings in the period in which the hedged transaction settles. The gain recognized in AOCI was $2.2 million for the nine months ended September 28, 2023. Within the next 12 months, the Company expects to recognize a gain of ($6.3) million in earnings related to the foreign currency forward contracts. As of September 28, 2023, the maximum term of the hedged forecasted transaction was 9 months.

See Note 14 Derivative and Hedging Activities to our condensed consolidated financial statements included in Part I of this Quarterly Report for more information.

Debt and Other Financing Arrangements

As of September 28, 2023, the outstanding balance of the senior secured Term Loan B Credit Agreement was $589.5 million and the carrying value was $572.6 million.

As of September 28, 2023, the outstanding balance of the 2023 Notes and the 2028 Notes was $0.0 million and $700.0 million, respectively, and the carrying value was $0.0 million and $696.4 million, respectively.

As of September 28, 2023, the outstanding balance of the Second Lien 2025 Notes, First Lien 2025 Notes, and 2026 Notes was $1,200.0 million, $20.8 million, and $300.0 million, respectively, and the carrying value was $1,193.8 million, $20.8 million, and $299.0 million.

As of September 28, 2023, the outstanding balance of the First Lien 2029 Notes was $900.0 million and the carrying value was $888.0 million.

See Note 15 Debt to our condensed consolidated financial statements included in Part I of this Quarterly Report for more information.

Information Regarding Guarantors of Spirit’s Notes Registered Under the Securities Act of 1933

Spirit’s 2026 Notes are guaranteed by Spirit AeroSystems North Carolina, Inc., a wholly-owned subsidiary of the Company (“Spirit NC”) and the Company, and Spirit’s 2028 Notes are guaranteed by the Company. None of Spirit’s notes are guaranteed by Spirit’s or the Company's other domestic subsidiaries or any foreign subsidiaries (together, the “Non-Guarantor Subsidiaries”). The Company consolidates each of Spirit and Spirit NC in its consolidated financial statements. Spirit and Spirit NC are both 100 percent-owned and controlled by the Company. The Company's guarantees of Spirit’s indebtedness are full and unconditional, except that the guarantees may be automatically released and relieved upon satisfaction of the requirements for legal defeasance or covenant defeasance under the applicable indenture being met. The Company's guarantees are also subject to a standard limitation which provides that the maximum amount guaranteed by the Company will not exceed the maximum amount that can be guaranteed without making the guarantee void under fraudulent conveyance laws.

The guarantees of the Company and Spirit NC with respect to Spirit’s 2026 Notes are made on a joint and several basis. The guarantee of Spirit NC is not full and unconditional because Spirit NC can be automatically released and relieved of its obligations under certain circumstances, including if it no longer guarantees Spirit’s credit facility. Like the Company's guarantees, the guarantee of Spirit NC is subject to a standard limitation which provides that the maximum amount guaranteed by Spirit NC will not exceed the maximum amount that can be guaranteed without making the guarantee void under fraudulent conveyance laws.

All of the existing guarantees by the Company and Spirit NC rank equally in right of payment with all of the guarantors’ existing and future senior indebtedness. The secured indebtedness of the Company and Spirit NC (including guarantees of Spirit’s existing and future secured indebtedness) will be effectively senior to guarantees of any unsecured indebtedness to the extent of the value of the assets securing such indebtedness. Future guarantees of subordinated indebtedness will rank junior to any existing and future senior indebtedness of the guarantors. The guarantees are structurally junior to any debt or obligations of non-guarantor subsidiaries, including all debt or obligations of subsidiaries that are released from their guarantees of the notes. As of September 28, 2023, indebtedness of our non-guarantor subsidiaries included $160.2 million of outstanding borrowings under intercompany agreements with guarantor subsidiaries and $17.9 million of finance leases of our non-guarantor subsidiaries. Based on our understanding of Rule 3-10 of Regulation S-X (“Rule 3-10”), we believe that the Company's guarantees of Spirit’s indebtedness comply with the conditions set forth in Rule 3-10, which enable us to present summarized financial information for the Company, Spirit and Spirit NC, which is a consolidated guarantor subsidiary, in accordance with Rule 13-01 of Regulation S-X. The summarized financial information excludes information regarding the non-guarantor subsidiaries. In accordance with Rule 3-10, separate financial statements of the guarantor subsidiaries have not been presented. The following tables include summarized financial information of Spirit, the Company, and Spirit NC (together, the “obligor group”). Investments in and equity in the earnings of the Company's Non-Guarantor Subsidiaries, which are not a member of the obligor group, have been excluded. The summarized financial information of the obligor group is presented on a combined basis for Spirit and the Company, and separately for Spirit NC, with intercompany balances and transactions between entities in the obligor group eliminated. The obligor group’s amounts due from, amounts due to and transactions with Non-Guarantor Subsidiaries have been presented in separate line items, if they are material. There are no non-controlling interests in any of the obligor group entities.

Supply Chain Financing Applicable to Suppliers

We have provided certain suppliers with access to a supply chain financing program through a facility with a third-party financing institution. Our suppliers’ ability to access the program is primarily dependent upon the strength of our financial condition and certain qualifying criteria. This program was primarily entered into as a result of seeking payment term extensions with suppliers, and the program allows suppliers to monetize the receivables prior to their payment date, subject to payment of a discount. While our suppliers’ access to this supply chain financing program could be curtailed if our credit ratings are downgraded due to a potential reduction in the capacity of the facility, we do not expect that changes in the availability of supply chain financing to our suppliers will have a significant impact on our liquidity.

The balance of confirmed obligations to suppliers who elected to participate in the supply chain financing program included in our accounts payable balance as of September 28, 2023 and September 29, 2022 was $112.7 million and $103.5 million, respectively. Confirmed obligations to suppliers who elected to participate in the supply chain financing program increased by $10.7 million and $44.6 million during the nine-month periods ended September 28, 2023 and September 29, 2022, respectively. The changes in each period primarily reflect purchases from suppliers related to production levels during the applicable period.

See Note 25 Supplier Financing to our condensed consolidated financial statements included in Part I of this Quarterly Report for more information.

Advance Payments

Advances on the B787 Program.  Boeing has made advance payments to Spirit under the B787 Supply Agreement that are required to be repaid to Boeing by way of offset against the purchase price for future shipset deliveries. As of September 28, 2023, the amount of advance payments received by us from Boeing under the B787 Supply Agreement and not yet repaid was approximately $194.5 million. 

CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

You should read the discussion of our financial condition and results of operations in conjunction with the unaudited condensed consolidated financial statements and the notes to the unaudited condensed consolidated financial statements appearing elsewhere in this Quarterly Report. The section may include “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements reflect our current expectations or forecasts of future events. Forward-looking statements generally can be identified by the use of forward-looking terminology such as “aim,” “anticipate,” “believe,” “could,” “continue,” “estimate,” “expect,” “forecast,” “goal,” “intend,” “may,” “might,” “objective,” “plan,” “predict,” “project,” “should,” “target,” “will,” “would,” and other similar words, or phrases, or the negative thereof, unless the context requires otherwise. These statements reflect management’s current views with respect to future events and are subject to risks and uncertainties, both known and unknown, including, but not limited to, those described in the “Risk Factors” section of the 2022 Form 10-K. Our actual results may vary materially from those anticipated in forward-looking statements. We caution investors not to place undue reliance on any forward-looking statements.

Important factors that could cause actual results to differ materially from those reflected in such forward-looking statements and that should be considered in evaluating our outlook include, but are not limited to, the following:

•the continued fragility of the global aerospace supply chain including our dependence on our suppliers, as well as the cost and availability of raw materials and purchased components, including increases in energy, freight, and other raw material costs as a result of inflation or continued global inflationary pressures;

•our ability and our suppliers’ ability, or willingness, to meet stringent delivery (including quality and timeliness) standards and accommodate changes in the build rates or model mix of aircraft under existing contractual commitments, including the ability or willingness to staff appropriately or expend capital for current production volumes and anticipated production volume increases;

•the ability to maintain continuing, uninterrupted production at our manufacturing facilities and our suppliers’ facilities;

•our ability, and our suppliers' ability, to attract and retain the skilled work force necessary for production and development in an extremely competitive market;

•the effect of economic conditions, including increases in interest rates and inflation, on the demand for our and our customers’ products and services, on the industries and markets in which we operate in the U.S. and globally, and on the global aerospace supply chain;

•the general effect of geopolitical conditions, including Russia’s invasion of Ukraine and the resultant sanctions being imposed in response to the conflict, including any trade and transport restrictions;

•the recent outbreak of war in Israel and the Gaza Strip and the potential for expansion of the conflict in the surrounding region, which may impact certain suppliers' ability to continue production or make timely deliveries of supplies required to produce and timely deliver our products, and may result in sanctions being imposed in response to the conflict, including trade and transport restrictions;

•our relationships with the unions representing many of our employees, including our ability to successfully negotiate new agreements, and avoid labor disputes and work stoppages with respect to our union employees;

•the impact of significant health events, such as pandemics, contagions, or other public health emergencies (including the COVID-19 pandemic) or fear of such events, on the demand for our and our customers’ products and services, the industries, and the markets in which we operate in the U.S. and globally;

•the timing and conditions surrounding the full worldwide return to service (including receiving the remaining regulatory approvals) of the B737 MAX, future demand for the aircraft, and any residual impacts of the B737 MAX grounding on production rates for the aircraft;

•our reliance on The Boeing Company (“Boeing”) and Airbus Group SE and its affiliates (collectively, “Airbus”) for a significant portion of our revenues;

•the business condition and liquidity of our customers and their ability to satisfy their contractual obligations to the Company;

53

•the certainty of our backlog, including the ability of customers to cancel or delay orders prior to shipment on short notice, and the potential impact of regulatory approvals of existing and derivative models;

•our ability to accurately estimate and manage performance, cost, margins, and revenue under our contracts, and the potential for additional forward losses on new and maturing programs;

•our accounting estimates for revenue and costs for our contracts and potential changes to those estimates;

•our ability to continue to grow and diversify our business, execute our growth strategy, and secure replacement programs, including our ability to enter into profitable supply arrangements with additional customers;

•the outcome of product warranty or defective product claims and the impact settlement of such claims may have on our accounting assumptions;

•competitive conditions in the markets in which we operate, including in-sourcing by commercial aerospace original equipment manufacturers;

•our ability to successfully negotiate, or re-negotiate, future pricing under our supply agreements with Boeing, Airbus and other customers;

•the possibility that our cash flows may not be adequate for our additional capital needs;

•any reduction in our credit ratings;

•our ability to access the capital or credit markets to fund our liquidity needs, and the costs and terms of any additional financing;

•our ability to avoid or recover from cyber or other security attacks and other operations disruptions;

•legislative or regulatory actions, both domestic and foreign, impacting our operations, including the effect of changes in tax laws and rates and our ability to accurately calculate and estimate the effect of such changes;

•spending by the U.S. and other governments on defense;

•pension plan assumptions and future contributions;

•the effectiveness of our internal control over financial reporting;

•the outcome or impact of ongoing or future litigation, arbitration, claims, and regulatory actions or investigations, including our exposure to potential product liability and warranty claims;

•adequacy of our insurance coverage;

•our ability to continue selling certain receivables through supplier financing programs; and

•our ability to effectively integrate recent acquisitions, along with other acquisitions we pursue, and generate synergies and other cost savings therefrom, while avoiding unexpected costs, charges, expenses, and adverse changes to business relationships and business disruptions;

•the risks of doing business internationally, including fluctuations in foreign currency exchange rates, impositions of tariffs or embargoes, trade restrictions, compliance with foreign laws, and domestic and foreign government policies.

Any consolidation, merger, acquisition of voting stock or sale, assignment or transfer of all or substantially all of the assets of Seller that is not prohibited by the immediately preceding

sentence shall not constitute an “assignment” for purposes of this GTA and shall not be prohibited by, or require Boeing’s consent under, this Section [20.4/28.3].

A Disqualified Person is:

(i)a Person, a principal business of which is as an original equipment manufacturer of commercial aircraft, defense systems, satellites, space launch vehicles or space vehicles;

For the avoidance of doubt, Boeing and Seller agree that HMSGTA MWS and Supplemental License Agreements WS-001/-002/-003 and -004 may be assigned to the third party receiving assignment of this GTA and its corresponding SBP’s. Any other Supplemental License Agreement between Boeing and Seller will be subject to the assignment terms of HMSGTA MWS.

16.Repudiation. Spirit and Boeing will amend the 787 GTA and the Sustaining GTA to add the following new 787 GTA Section 8.5 and Sustaining GTA Section 13.3:

[8.5/13.3] Repudiation

The Parties agree that repudiation by Seller of timely delivery under GTA BCA-65530-0016, GTA BCA-65520-0032, SBP MS-65530-0019, or SBP MS-65530-0016 would cause irreparable harm to Boeing for which damages would not be an adequate remedy. Accordingly, in the event Seller repudiates timely delivery under any of the aforementioned agreements, Boeing will be entitled to equitable relief, including but not limited to, specific performance and preliminary and permanent injunctions.

17.Complete Agreement. This MOA constitutes the complete and exclusive agreement between the Parties with respect to the subject matter set forth herein and supersedes all previous agreements between the Parties relating thereto, whether written or oral.

Boeing and Spirit hereby irrevocably consent to and submit themselves exclusively to the jurisdiction of the applicable courts of King County, Washington and the federal courts of Washington State for the purpose of any suit, action or other judicial proceeding arising out of or connected with this MOA. Boeing and Spirit hereby waive and agree not to assert by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that (a) Boeing and Spirit are not personally subject to the jurisdiction of the above-named courts; (b) the suit, action, or proceeding is brought in an inconvenient forum; or (c) the venue of the suit, action, or proceeding is improper.

19.No Admission of Liability.

20.Confidential Treatment. The information contained herein is confidential business information. The Parties will limit the disclosure of this MOA's contents to employees with a need to know and who understand that they are not to disclose its contents to any other person or entity without the prior written consent of the other Party. Notwithstanding the above, the Parties may file this MOA with the SEC if legally required to do so but must give the other Party two business days’ advance notice and will omit confidential information as permitted by applicable law as appropriate after providing the other Party the opportunity to provide comments. Nothing in this

section will prevent either Party from making reasonable disclosures during the course of its earnings calls.

21.Interpretation. Each Party has had the opportunity to draft, review, and edit this MOA. Accordingly, no presumption for or against either Party arising out of drafting all or any part of this MOA will be applied in any action relating to or arising from this MOA; and the Parties hereby waive the benefit of any statute or common-law rule providing that, in cases of uncertainty, language should be interpreted against the Party who caused the uncertainty to exist.

The Executive represents that he has not made, and agrees that he will not make, to any third party any disparaging, untrue, or misleading written or oral statements about or relating to the Company or the Parent, or their products or services (or about or relating to any officer, director, agent, employee, or other person acting on the Company’s or the Parent’s behalf). The Company agrees to direct its “named executive officers,” as such term is defined under Item 402 of Regulation S-K promulgated by the Securities and Exchange Commission, and the members of its Board of Directors, not to make, and use reasonable efforts to ensure that such named executive officers and directors, will not make, to any third party or to employees and directors of the Company and the Parent, any disparaging, untrue, or misleading written or oral statements about or relating to the Executive or the services of the Executive as an employee or director of the Company and Parent. The foregoing provision shall not be effective with respect to any information required to be disclosed by the Executive, Company or named executive officers by the order of a court or administrative agency, subpoena or other legal or administrative demand, nor will it prevent any permitted activity as described in Paragraph 13 below.

12.Protective Agreement. The Executive acknowledges and agrees that he shall continue to be bound by the terms and conditions of Section 4 of the Employment Agreement, the terms of

which are incorporated herein by reference; provided that, the parties agree that the noncompetition and non-solicitation periods as set forth under Sections 4(c) and (d) of the Employment Agreement shall be applicable for a period of one year following the Separation Date.

In the event that the Executive wishes to pursue an opportunity that may implicate Sections 4(c) or 4(d) of the Employment Agreement, the Executive agrees that he will present the details of such opportunity to the Company’s Chief Administrative Offer, and the Company will act reasonably in considering whether the Executive would be permitted to pursue such opportunity, including in considering whether a potential business activity is competitive with the Business (as defined in the Employment Agreement).

13.Permitted Activities. Notwithstanding any other provision of this Agreement or the Employment Agreement, nothing in this Agreement is intended to, or does, preclude Executive or any other individual from (i) contacting, reporting to, responding to an inquiry from, filing a charge or complaint with, communicating with, or otherwise participating in an investigation conducted by, the EEOC, the Securities and Exchange Commission, the Department of Labor, the National Labor Relations Board, the Occupational Safety and Health Administration, or any other federal, state, or local governmental agency, commission, or regulatory body; (ii) giving truthful testimony or making statements under oath in response to a subpoena or other valid legal process or in any legal proceeding; (iii) otherwise making truthful statements as required by law or valid legal process; (iv) engaging in any concerted or other legally protected activities; or (v) disclosing a trade secret in confidence to a governmental official, directly or indirectly, or to an attorney, if the disclosure is made solely for the purpose of reporting or investigating a suspected violation of law.

Furthermore, notwithstanding the provisions herein, the Executive is hereby notified that the immunity provisions in Section 1833 of title 18 of the United States Code provide that an individual cannot not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (i) is made (A) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. The Executive likewise understands that, if the Executive files a lawsuit for retaliation by the Company for reporting a suspected violation of law, the Executive may disclose the Company’s trade secret(s) to his attorney and use the trade secret information in the court proceeding, if the Executive (i) files any document containing the trade secret under seal; and (ii) does not disclose the trade secret, except pursuant to court order.

14.Severability. If any provision of this Agreement shall be found by a court of competent jurisdiction to be invalid or unenforceable, in whole or in part, then such provision shall be construed and/or modified or restricted to the extent and in the manner necessary to render the same valid and enforceable, or shall be deemed excised from this Agreement, as the case may require, and this Agreement shall be construed and enforced to the maximum extent

permitted by law, as if such provision had been originally incorporated herein as so modified or restricted, or as if such provision had not been originally incorporated herein, as the case may be. The parties further agree to seek a lawful substitute for any provision found to be unlawful; provided, that, if the parties are unable to agree upon a lawful substitute, the parties desire and request that a court or other authority called upon to decide the enforceability of this Agreement modify the Agreement so that, once modified, the Agreement will be enforceable to the maximum extent permitted by the law in existence at the time of the requested enforcement.

15.Waiver. A waiver by the Company of a breach of any provision of this Agreement by the Executive shall not operate or be construed as a waiver or estoppel of any subsequent breach by the Executive. No waiver shall be valid unless in writing and signed by an authorized officer of the Company.

16.Miscellaneous Provisions.

(a)Representations. The Executive represents and certifies that he has carefully read and fully understands all of the provisions and effects of this Agreement, has knowingly and voluntarily entered into this Agreement freely and without coercion, and acknowledges that the Company advised him to consult with an attorney prior to executing this Agreement. The Executive is voluntarily entering into this Agreement and neither the Company nor Parent nor any of their respective employees, officers, directors, representatives, attorneys or other agents made any representations concerning the terms or effects of this Agreement other than those contained in the Agreement itself and the Executive is not relying on any statement or representation by the Company or any other Released Parties in executing this Agreement. The Executive is relying on his own judgment and that of his attorney to the extent so retained. The Executive also specifically affirms that this Agreement clearly expresses his intent to waive fraudulent inducement claims, and that he disclaims any reliance on representations about any of the specific matters in dispute.

(b)Return of Property. In entering into this Agreement or as agreed upon by the Parties, the Executive represents that he has returned or he shall return to the Company all of the Company’s and the Parent’s and their respective subsidiaries’ property that has been in the Executive’s possession, custody or control, including, without limitation, (i) all keys, access cards, badges, credit cards, mobile devices, computer hardware, computer software, data, materials, documents, records, policies, client and customer information, marketing information, design information, specifications and plans, data base information and lists, and any other property or information of the Company, the Parent and their subsidiaries (whether those materials are in paper or computer-stored form), and (ii) all documents and other property containing, summarizing, or describing any Confidential Information (as defined in the Employment Agreement), including all originals and copies. The Executive affirms that (A) he will not retain any such property or information in any form (except as permitted in accordance with the following clause), and will not give copies of such property or information or disclose their contents to any

other person (B) within fourteen (14) business days from the Effective Date of this Agreement, the Executive will make his cell phone (and any other personal devices used for work-related communications) available to the Company, or an approved third-party vendor, and provide any necessary information, i.e. pass codes, etc., to allow access to text messages and other communications for the purpose of downloading and electronically retaining the same so the Company is compliant with its requirements as to all applicable legal hold(s); the Executive agrees to preserve all such content on the device(s) prior to the time the Company completes this process.

17.Complete Agreement. This Agreement (and, as referenced herein, the Employment Agreement) sets forth the entire agreement between the parties, and fully supersedes any and all prior agreements or understandings, whether oral or written, between the parties pertaining to actual or potential claims arising from the Executive’s employment with the Company and the Parent or the termination of the Employment Agreement, provided, however, that all obligations, rights, and terms under Sections 4, 8 and 9 of the Employment Agreement, which are incorporated by reference herein, shall not be superseded and shall remain in full force and effect. The Executive expressly warrants and represents that no promise or agreement which is not herein expressed has been made to him in executing this Agreement.

18.No Assignment of Claims. The Executive represents that he has not assigned his rights with respect to any claim that the Executive releases hereunder to any third party.

19.No Admission of Liability. The Executive understands and acknowledges that this Agreement constitutes a compromise and settlement of any and all actual or potential disputed claims by the Executive. No action taken by the Company hereto, either previously or in connection with this Agreement, shall be deemed or construed to be (a) an admission of the truth or falsity of any actual or potential claims or (b) an acknowledgment or admission by the Company of any fault or liability whatsoever to the Executive or any third party.

20.Reimbursement. If the Executive or his heirs, executors, administrators, successors or assigns (a) is in breach of or breaches Paragraphs 9, 10, 11, 12, 16(b) or 21 of this Agreement, or (b) files a lawsuit of any kind or nature against one or more of the Released Parties, or a claim of any kind or nature against one or more of the Released Parties, the Executive or his heirs, executors, administrators, successors or assigns shall be obligated to tender back to the Company, as a contractual remedy hereunder, all payments made to him or them under Paragraph 3 of this Agreement. The Company and the Executive acknowledge that the remedy set forth hereunder is not to be considered a form of liquidated damages and the tender back shall not be the exclusive remedy hereunder.

21.Future Cooperation. Upon the reasonable written request to the Executive by the Company’s general counsel or Board of Directors, the Executive agrees to provide reasonable assistance and cooperation, without the necessity of subpoena, in any matter or matters (including but not limited to any regulatory, law enforcement or judicial investigations or proceedings, mediations, arbitrations or lawsuits, any claim negotiations with customers or suppliers, or otherwise) of which the Company identifies the Executive as potentially having knowledge

(or otherwise relating to Executive’s expertise or experience), where deemed appropriate by the Company, including providing information, preparing for, and/or attending any hearing or proceeding (whether relating to the Company’s defense or prosecution of any existing or future actions, arbitrations, claims or litigations or otherwise). The Company will reimburse the Executive for the reasonable costs and expenses incurred by the Executive, including any lost wages, in connection therewith, provided however, that such reimbursements (i) are not intended to influence in any way the testimony Executive gives under oath, and Executive agrees to testify truthfully and (ii) do not encompass attorney’s fees incurred by Executive. The Company’s agreement to reimburse Executive through this Agreement is not based, conditioned or contingent in any way on the substance, content or efficacy of Executive’s testimony, or the outcome of any particular matter.

22.Amendment. This Agreement may not be altered, amended, or modified except in writing signed by both the Executive and the Company.

23.Joint Participation. The parties hereto participated jointly in the negotiation and preparation of this Agreement, and each party has had the opportunity to obtain the advice of legal counsel and to review and comment upon the Agreement. Accordingly, it is agreed that no rule of construction shall apply against any party or in favor of any party. This Agreement shall be construed as if the parties jointly prepared this Agreement, and any uncertainty or ambiguity shall not be interpreted against one party and in favor of the other.

AGREEMENT

NOW THEREFORE, in consideration of the foregoing, and the representations, warranties, and covenants hereinafter, the parties hereto agree as follows:

Section 1.Employment. The Company hereby hires Employee as its President and Chief Executive Officer, and Employee agrees to serve in such capacity and to also serve as President and Chief Executive Officer of Holdings, and to perform such duties and services in and about the Business as are appropriate for a person in such positions. Employee shall be Kansas-based during his employment hereunder, and Employee’s office will be at the Company’s headquarters in Wichita, Kansas. Employee shall devote Employee’s full business time to this employment and to Employee’s service to the Company and Holdings. Employee’s employment hereunder shall commence as of the Effective Date and shall continue until termination of the Agreement in accordance with its terms (the “Employment Period”). Employee shall report directly to the Board of Directors of Holdings (the “Board”). During the Employment Period, Employee will continue to serve as a member of the Board, but will serve in the capacity of a non-independent director during such period.

Section 2.Performance. Employee shall use Employee’s reasonable best efforts and skill to faithfully enhance and promote the Business and the welfare and best interests of the Company and Holdings. Employee shall comply with all rules and regulations of the

Company and Holdings that are applicable to Employee, follow all laws and regulations of applicable government authorities, and be governed by reasonable decisions and instructions of the Company as are consistent with job duties as described above. Notwithstanding the foregoing, Employee will be permitted to, with the prior written consent of the Board, act or serve as a director, trustee, committee member, or principal of any type of business, civic, or charitable organization as long as (a) such activities are disclosed in writing to the Company’s Global Compliance office in accordance with the Company’s Code of Conduct, and (b) such activities or services do not materially interfere with the performance of Employee’s duties or responsibilities to the Company or Holdings.

Section 3.Compensation. Except as otherwise provided for herein, for all services to be performed by Employee in any capacity hereunder, including all services performed for the Company or Holdings and including any services as an officer, director, member of any committee, or any other duties assigned Employee throughout the Employment Period, the Company shall pay or provide Employee with the following, and Employee shall accept the same, as compensation for the performance of Employee’s undertakings and the services to be rendered by Employee:

(a)Base Salary. Employee will be entitled to an annualized salary at the rate of Two Million Dollars ($2,000,000.00) (the “Base Salary”), which shall be paid in accordance with the Company’s policies and procedures as in effect from time to time.

(b)Annual Incentive Compensation. Employee shall not be eligible for annual incentive compensation under the Spirit AeroSystems Holdings, Inc. short-term incentive program (the “STIP”) maintained pursuant to and in accordance with the terms and conditions of the Spirit AeroSystems Holdings, Inc. 2014 Omnibus Incentive Plan, as amended or restated from time to time (the “OIP”).

(c)Long-Term Incentive Awards. Employee will be eligible to receive a one-time award of restricted stock units under the Spirit AeroSystems Holdings Inc. long-term incentive program (the “LTIP”), granted by the Board or its compensation committee, pursuant to and in accordance with the terms and conditions of the OIP and the Company’s standard time-based restricted stock unit award agreement for U.S. participants. Employee’s one-time LTIP award opportunity will have an aggregate target grant date fair value equal to 400% of Base Salary, determined as of the Effective Date. Employee’s LTIP award will be granted as soon as administratively feasible (but in all events within thirty (30) days) following the Effective Date of this Agreement.

(d)Relocation Benefits and Related Perquisites. During the Employment Period, Employee will be entitled to (i) temporary housing in Wichita, Kansas, which shall be provided pursuant to the terms of the Company’s Corporate Domestic Relocation Guide — Level 4 Policy (Senior Vice President and Above), (ii) use of

corporate aircraft to travel between Wichita, Kansas and Seattle, Washington, which use shall be provided in accordance with the terms and conditions of the Company’s aircraft policy, and (iii) an automobile allowance provided in accordance with the terms of the Company’s automobile policy.

(e)Other Benefit Plans. Employee shall also be eligible to participate in the Company’s other employee benefit plans, policies, practices, and arrangements as the same may be offered to other officers of the Company from time to time, including, without limitation, (i) any retirement plan, excess or supplementary plan, profit sharing plan, savings plan, health and dental plan, disability plan, survivor income and life insurance plan, executive financial planning program, or other arrangement, or any successors thereto; and (ii) such other benefit plans as the Company may establish or maintain from time to time (collectively the “Benefit Plans”); provided, however, that nothing in this Section 3(e) shall be construed as providing for participation in the Company’s STIP or Deferred Compensation Plan. Employee’s entitlement to any other compensation or benefits shall be determined in accordance with the terms and conditions of the Benefit Plans and other applicable programs, practices, and arrangements then in effect.

(f)Earned Time Off. Employee will be provided with earned time off and twelve (12) paid holidays each year in accordance with the Company’s policies and practices in effect from time to time. Notwithstanding any contrary policy or practice, however, Employee will be credited with a minimum of twenty-five (25) days of earned time off per year.

(g)Fringe Benefits. Employee will be provided with all fringe benefits and perquisites in accordance with the Company’s policies as the same may be amended from time to time.

(h)Withholding Taxes. The Company shall have the right to deduct from all payments made to Employee hereunder any federal, state, or local taxes required by law to be withheld.

(i)Expenses. During Employee’s employment, the Company shall promptly pay or reimburse Employee for all reasonable out-of-pocket expenses incurred by Employee in the performance of duties hereunder in accordance with the Company’s policies and procedures then in effect.

The Company and Employee each acknowledge that amounts paid under this Agreement, the OIP or the other Benefit Plans are subject to any policy on the recovery of compensation (i.e., a so-called “clawback policy”), as it exists now or as later adopted, and as thereafter amended from time to time. The Company hereby represents and affirms that the size of the LTIP award provided hereunder was not determined wholly or in part by a Company financial reporting measure.

Section 4.Restrictions.

(a)Acknowledgments. Employee acknowledges and agrees that: (i) during the term of Employee’s employment, because of the nature of Employee’s responsibilities and the resources provided by the Company, Employee will acquire valuable and confidential skills, information, trade secrets, and relationships with respect to the Business; (ii) Employee may develop on behalf of the Company and Holdings a personal acquaintance and/or relationship with various persons, including, but not limited to, customers and suppliers, which acquaintances may constitute the Company’s or Holdings’ only contact with such persons, and, as a consequence of the foregoing, Employee will occupy a position of trust and confidence with respect to the Company’s and Holdings’ affairs; (iii) the Business involves the marketing and sale of the Company’s products and services to customers throughout the entire world, the Company’s and Holdings’ competitors, both in the United States and internationally, consist of both domestic and international businesses, and the services to be performed by Employee for the Company and Holdings involve aspects of both the Company’s and Holdings’ domestic and international business; and (iv) it would be impossible or impractical for Employee to perform Employee’s duties for the Company and Holdings without access to the Company’s and Holdings’ confidential and proprietary information and contact with persons that are valuable to the goodwill of the Company and Holdings. Employee acknowledges that if Employee went to work for, or otherwise performed services for, a third party engaged in a business substantially similar to the Business, the disclosure by Employee to a third party of such confidential and proprietary information and/or the exploitation of such relationships would harm the Company’s and Holdings’ Business.

(b)Reasonableness. In view of the foregoing and in consideration of the remuneration to be paid to Employee, Employee agrees that it is reasonable and necessary for the protection of the goodwill and business of the Company and Holdings and their respective subsidiaries as may exist from time to time (collectively, the Company, Holdings and their respective subsidiaries as may exist from time to time are referred to herein as the “Company Group”) that Employee make the covenants contained in this Agreement regarding the conduct of Employee during and subsequent to Employee’s employment by the Company, and that the Company Group may suffer injury if Employee engages in conduct prohibited by this Agreement.

(c)Non-Compete. During the term of Employee’s employment by the Company and for a period of (i) in the case of involuntary termination by the Company without Cause or termination by Employee for Good Reason, one (1) year after termination of employment, and (ii) in the case of termination of employment for any other reason, two (2) years after termination of such employment, Employee shall not, directly or indirectly, anywhere in the world: own, manage, operate,

control, be employed by, solicit sales for, invest in, participate in, advise, consult with, or be professionally invested in or engaged with the ownership, management, operation, or control of any business which is engaged, in whole or in part, in the Business, or any business that is competitive therewith or any portion thereof, except in each case for the exclusive benefit of the Company Group; provided, however, that Employee shall not be deemed to have breached this provision if (A) Employee’s sole relation with any such entity consists of Employee’s holding, directly or indirectly, not greater than two percent (2%) of the outstanding securities of a company which are either listed on or through a national securities exchange or owned through an investment in a private equity or other commingled fund, or (B) Employee provides services to (or owns the related equity of) such an entity so long as the combined revenues of such entity and its affiliates relating to the competition with the Business or competitive activities as described in this paragraph represent in the aggregate less than five percent (5%) of the combined revenues of such entity and its affiliates and so long as Employee has no direct involvement in any activities that compete with the Business.

(d)Non-Solicitation. In addition, during the term of Employee’s employment by the Company and for a period of (i) in the case of involuntary termination by the Company without Cause or termination by Employee for Good Reason, one (1) year after termination of employment, and (ii) in the case of termination of employment for any other reason, two (2) years after termination of such employment, Employee shall not, directly or indirectly: solicit or take any action to induce (A) any employee to quit or terminate their employment with any member of the Company Group other than in connection with Employee’s good faith performance of his duties during the Employment Period or (B) any customer to cease doing business with, or reduce or modify its business with, any member of the Company Group other than in connection with Employee’s good faith performance of his duties during the Employment Period. This Section 4(d) shall not prohibit general solicitations for employment not specifically directed at employees of any member of the Company Group.

(e)Confidentiality.

(i)Confidential Information. For purposes of this Agreement, “Confidential Information” means any information (whether in written, oral, graphic, schematic, demonstration, or electronic format, whether or not specifically marked or identified as confidential, and whether obtained by Employee before or after the Effective Date), not otherwise publicly disclosed by a member of the Company Group, regarding (without limitation) any member of the Company Group, or their Business, customers, suppliers, business partners, prospects, contacts, contractual arrangements, discussions, negotiations, evaluations, labor negotiations, bids, proposals, aircraft programs, costs, pricing, financial condition or results, plans,

strategies, governmental relations, projections, analyses, methods, processes, models, tooling, know-how, trade secrets, discoveries, research, developments, inventions, engineering, technology, proprietary information, intellectual property, designs, computer software, intelligence, legal or regulatory compliance, accounting decisions, opportunities, challenges, and any other information of a confidential or proprietary nature or that is competitively valuable to any member of the Company Group by virtue of not being generally known to the public. Notwithstanding the foregoing, Confidential Information will not include any information that (A) Employee is required to disclose by a court order, subpoena, or other legal demand, so long as (1) Employee gives the Company written notice and an opportunity to contest or seek confidential treatment of such disclosure; and (2) Employee fully cooperates at the Company’s expense with any such contest or confidential treatment request; (B) has been otherwise publicly disclosed, or made publicly available by Company or Holdings; or (C) was obtained by Employee in good faith from a source that was under no obligation of confidentiality to any member of the Company Group or any customer or supplier.

(ii)Non-Use and Non-Disclosure. Without the express written consent of the Company or Holdings, Employee will not at any time (whether during the Employment Period or after any termination of employment for any reason) use for any purpose (other than for the exclusive benefit of the Company and Holdings) or disclose to any person (except at the direction of the Company or Holdings) any Confidential Information.

(iii)Permitted Disclosures. Notwithstanding the foregoing or any other provision of this Agreement, and specifically Section 4(e)(ii) above, nothing in this Agreement or in any other agreement between Employee and the Company or Holdings is intended to, or does, preclude Employee from (A) contacting, reporting to, responding to an inquiry from, filing a charge or complaint with, communicating with, or otherwise participating in an investigation conducted by the U.S. Securities and Exchange Commission, or any other federal, state, or local governmental agency, commission, or regulatory body; (B) giving truthful testimony or making statements under oath in response to a subpoena or other valid legal process or in any legal proceeding; (C) otherwise making truthful statements as required by law or valid legal process; (D)engaging in any other legally protected activities; or (E) making any other disclosures that are protected under the whistleblower provisions of any applicable law. Furthermore, pursuant to the Defend Trade Secrets Act of 2016, Employee will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that (1) is made (x) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and (y) solely for the purpose of reporting

or investigating a suspected violation of law; or (2) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Employee likewise understands that, if he files a lawsuit for retaliation by the Company for reporting a suspected violation of law, Employee may disclose the trade secret(s) of the Company or Holdings to Employee’s attorney and use the trade secret information in the court proceeding, if Employee (I) files any document containing the trade secret under seal; and (II) does not disclose the trade secret, except pursuant to court order.

(f)Effect of Breach. Employee agrees that a breach of this Section 4 cannot adequately be compensated by money damages and, therefore, each member of the Company Group shall be entitled, in addition to any other right or remedy available to it (including, but not limited to, an action for damages), to seek an injunction restraining such breach or a threatened breach and to specific performance of such provisions, and Employee hereby consents to the issuance of such injunction and to the ordering of specific performance, without the requirement of any member of the Company Group to post a bond or other security.

(g)Other Rights Preserved. Nothing in this Section eliminates or diminishes rights which the Company may have with respect to the subject matter hereof under any other agreements, governing statutes, or under provisions of law, equity, or otherwise.

(h)Section 409A. The Company and Employee intend that the payments and benefits provided for in this Agreement either be exempt from Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), or be provided in a manner that complies with Section 409A of the Code, and any ambiguity herein shall be interpreted so as to be consistent with the intent of this Section 4(h). Employee acknowledges that Section 409A of the Code places responsibility for additional taxes and penalties on Employee and not the Company in the event of a breach of the provisions of Section 409A of the Code. Notwithstanding anything contained herein to the contrary, all payments and benefits under Section 6(b) of this Agreement shall be paid or provided only at the time of a termination of Employee’s employment that constitutes a “separation from service” from the Company within the meaning of Section 409A of the Code and the regulations and guidance promulgated thereunder (determined after applying the presumptions set forth in Treas. Reg. Section 1.409A-1(h)(1)). Further, if at the time of Employee’s termination of employment with the Company, Employee is a “specified employee” as defined in Section 409A of the Code as determined by the Company in accordance with Section 409A of the Code, and the deferral of the commencement of any payments or benefits otherwise payable hereunder as a result of such termination of employment is necessary in order to prevent any accelerated or additional tax under Section 409A of the Code, then the Company

will defer the commencement of the payment of any such payments or benefits hereunder (without any reduction in payments or benefits ultimately paid or provided to Employee) until the date that is at least six (6) months following Employee’s termination of employment with the Company (or the earliest date permitted under Section 409A of the Code), whereupon the Company will pay Employee a lump-sum amount equal to the cumulative amounts that would have otherwise been previously paid to Employee under this Agreement during the period in which such payments or benefits were deferred. Thereafter, payments will resume in accordance with this Agreement. For purposes of Section 409A of the Code, each of the payments that may be made under this Agreement are designated as separate payments.

Notwithstanding anything to the contrary in this Agreement, in-kind benefits and reimbursements provided under this Agreement during any calendar year shall not affect in-kind benefits or reimbursements to be provided in any other calendar year, other than an arrangement providing for the reimbursement of medical expenses referred to in Section 105(b) of the Code, and are not subject to liquidation or exchange for another benefit. Notwithstanding anything to the contrary in this Agreement, reimbursement requests must be timely submitted by Employee and, if timely submitted, reimbursement payments shall be promptly made to Employee following such submission, but in no event later than December 31st of the calendar year following the calendar year in which the expense was incurred. In no event shall Employee be entitled to any reimbursement payments after December 31st of the calendar year following the calendar year in which the expense was incurred. This Section shall only apply to in-kind benefits and reimbursements that would result in taxable compensation income to Employee.

Additionally, in the event that following the date hereof the Company or Employee reasonably determines that any compensation or benefits payable under this Agreement may be subject to Section 409A of the Code, the Company and Employee shall work together to adopt such amendments to this Agreement or adopt other policies or procedures (including amendments, policies and procedures with retroactive effect), or take any other commercially reasonable actions necessary or appropriate to (i) exempt the compensation and benefits payable under this Agreement from Section 409A of the Code and/or preserve the intended tax treatment of the compensation and benefits provided with respect to this Agreement or (ii) comply with the requirements of Section 409A of the Code and related Department of Treasury guidance.

Section 5.Termination. This Agreement and Employee’s employment shall terminate upon the following circumstances:

(a)Without Cause. At any time at the election of either Employee or the Company for any reason or no reason, without Cause (as defined below), but subject to the

provisions of this Agreement. It is expressly understood that Employee’s employment is strictly “at will” and may be terminated by either party at any time.

(b)Cause. At any time at the election of the Company for Cause. “Cause” for this purpose shall mean (i) Employee’s commission of a material breach of this Agreement or acts involving fraud, material and intentional dishonesty, material and intentional unauthorized disclosure of Confidential Information, the commission of a felony or other crime involving moral turpitude, or material violation of policies of any member of the Company Group made available to Employee; (ii) direct and deliberate acts constituting a material breach of Employee’s duty of loyalty to any member of the Company Group; (iii) Employee’s refusal or material failure (other than by reason of a Disability (as defined below)) to perform Employee’s job duties and responsibilities, including, but not limited to, any duties or responsibilities reasonably assigned to Employee by the Board, if such refusal or failure is not remedied within thirty (30) days after Employee receives written notice thereof from the Board; or (iv) (v) Employee’s inability to obtain and maintain the appropriate level of United States security clearance.

(c)Good Reason. At any time (subject to the notice and cure provisions included in this clause (c)) at the election of Employee for Good Reason. “Good Reason” for this purpose shall mean the occurrence of any of the following, in each case during the Employment Period and without Employee’s consent: (i) a material diminution in Employee’s Base Salary, other than a general reduction in Base Salary that does not exceed twenty percent (20%) and that affects similarly situated executives in substantially the same proportions; (ii) a material diminution in Employee’s title, authority, duties, reporting relationships or responsibilities; (iii) a requirement that Employee report to anyone other than the Board; or (iv) any other action or inaction with respect to the terms and conditions of Employee’s employment that constitutes a material breach by the Company of this Agreement. Employee cannot terminate employment for Good Reason unless (A) Employee has provided written notice to the Company of the existence of the circumstances providing grounds for termination for Good Reason within 30 days of the initial existence of the condition; (B) the condition specified in such notice must remain uncorrected for 30 days after receipt of such notice by the Company; and (C) the date of Employee’s termination of employment must occur within ninety (90) days after the initial existence of the condition specified in such notice.

(d)Death or Disability. Upon Employee’s death or Employee being unable, due to physical or mental disability (and after giving effect to reasonable accommodation, if available and required by applicable law), to render the services required to be rendered by Employee for a period of one hundred eighty (180) days during any twelve (12)-month period (“Disability”).

Section 6.Effect of Termination.

(a)Termination Other than Section 6(b). If Employee’s employment is terminated for any reason other than as described in Section 6(b) below, the Company will pay Employee’s compensation only through the last day of the Employment Period (less any amounts the Company may offset or deduct as specified in this Agreement or as otherwise permitted), and, except as may otherwise be expressly provided in this Agreement (including Section 3(e) hereof) or the OIP, the LTIP, or in any Benefit Plan, the Company shall have no further obligation to Employee.

(b)Non-Cause, Good Reason, Death, Disability, Retirement.

(i)If Employee’s employment is terminated by the Company without Cause or is terminated by Employee for Good Reason (each, a “Qualifying Termination”), then for as long as Employee complies with his continuing obligations under Section 4, Employee will be treated as one hundred percent (100%) vested in all time-based LTIP awards granted to Employee pursuant to this Agreement. The treatment of all outstanding LTIP awards granted to Employee during the Employment Period shall otherwise be governed by the terms of the OIP, the LTIP, and the applicable award agreements thereunder, including the terms thereunder that provide for 100% vesting upon Employee’s death, Disability, or Retirement (as such term is defined under the applicable LTIP award agreements).

(ii)Further, if Employee experiences a Qualifying Termination within twelve (12) months after a Change in Control (as defined below) (such termination, a “CIC Termination”), then as long as Employee complies with his continuing obligations under Section 4, Employee will receive severance in an amount equal to one (1) times Employee’s then-current annualized Base Salary rate, which severance will be payable in a single lump-sum cash payment within sixty (60) days following the date of termination, and, if, and only if, such CIC Termination occurs prior to the one (1) year anniversary of the Effective Date, Employee will also receive an additional single lump-sum cash payment within sixty (60) days following the date of termination, equal to the remaining amount of Base Salary that Employee would have received if Employee would have remained employed from the applicable date of termination through the one (1) year anniversary of the Effective Date.

(iii)“Change in Control” means, for purposes of this Agreement, (A) a transaction pursuant to which a Person, or more than one Person acting as a group, acquires more than fifty percent (50%) of the total voting power of Holdings (including, but not limited to, acquisition by merger,

consolidation, recapitalization, reorganization or sale or transfer of the Holdings’ equity interests); (B) a merger or consolidation involving Holdings in which Holdings is not the surviving entity; (C) a transaction that is a sale or transfer of all or substantially all of the assets of Holdings or the Company, if all or substantially all of the proceeds from such transaction are distributed to the stockholders of Holdings; or (iv) a majority of the members of the Board are replaced during any twelve (12) month period by directors whose appointment or election is not endorsed by a majority of the Board before the date of appointment or election. Capitalized Terms used in this definition, but not defined herein shall have the meaning assigned to them in the OIP.

(c)Release. With respect to any severance payable and accelerated vesting of previously unvested time-based LTIP awards that occurs solely by virtue of the operation of Section 6(c), Employee shall be entitled to such severance and vesting only if he signs an agreement acceptable to the Company (in a form that will be provided to Employee by the Company within seven (7) days following the end of the Employment Period, which form shall not contain additional restrictive covenants and which form, to the extent it includes any non-disparagement covenants, will reflect mutual obligations, the scope of which shall be established by the Company) that releases the Company and each other member of the Company Group from all actions, suits, claims, proceedings and demands, including those related to the Employment Period and the termination of employment (except for rights to benefits provided under Section 6(b) of this Agreement and under the Benefit Plans or as may otherwise be expressly provided in this Agreement). Employee must sign and tender the release as described above not later than sixty (60) days following Employee’s last day of employment, or such earlier date as required by the Company, and if Employee fails or refuses to do so (or if Employee exercises any revocation right as set forth in the release), Employee shall forfeit the right to such severance and accelerated vesting pursuant to Section 6(b) that would otherwise be due and payable. If vesting is accelerated solely pursuant to Section 6(b) of this Agreement, such vesting will occur as soon as administratively feasible following the execution and non-revocation of the release described in this Section 6(c). For the sake of clarity, the release requirements included in this Section 6(c) shall not apply to the extent that vesting of Employee’s LTIP awards occurs pursuant to the terms of the OIP, LTIP, and award agreement and absent the application of Section 6(b) of this Agreement.

(d)Return of Property. Upon termination of employment, and at any other time upon the Company’s request, Employee shall deliver all trade secret, confidential information, records, notes, data, memoranda, and equipment of any nature that are in Employee’s possession or under Employee’s control and that are the property of any member of the Company Group or relate to the business of the Company Group, and Employee shall pay to the Company any amounts due and

owing from Employee to the Company as specified in this Agreement; provided, however, Employee shall be permitted to retain his personal address book and his cell phone number.

(e)Survival. Employee’s obligations under Section 4 through Section 9 of this Agreement shall survive the expiration or termination of this Agreement and the end of the Employment Period. The Company shall have no obligation to provide the accelerated vesting set forth in Section 6(c) above unless and until Employee has fully complied with Employee’s obligations under this Section 6.

Section 7.Representations and Warranties.

(a)No Conflicts. Employee represents and warrants to the Company and Holdings that Employee is under no duty (whether contractual, fiduciary, or otherwise) that would prevent, restrict, or limit Employee from fully performing all duties and services for the Company and Holdings, and the performance of such duties and services shall not conflict with any other agreement or obligation to which Employee is bound. Employee agrees to comply with all obligations that Employee may have to prior employers and other third parties in the course of his employment with or service to the Company and Holdings.

(b)No Hardship. Employee represents and acknowledges that Employee’s experience and/or abilities are such that observance of the covenants contained in this Agreement will not cause Employee any undue hardship and will not unreasonably interfere with Employee’s ability to earn a livelihood.

Section 8.Alternative Dispute Resolution.

(a)Mediation. Employee and the Company Group agree to submit, prior to arbitration, all unsettled claims, disputes, controversies, and other matters in question between them arising out of or relating to this Agreement (including but not limited to any claim that the Agreement or any of its provisions is invalid, illegal, or otherwise voidable or void) or the dealings or relationship between Employee and the Company or Holdings (“Disputes”) to mediation in Wichita, Kansas and in accordance with the Commercial Mediation Rules of the American Arbitration Association then in effect. The mediation shall be private, confidential, voluntary, and nonbinding. Any party may withdraw from the mediation at any time before signing a settlement agreement upon written notice to each other party and to the mediator. The mediator shall be neutral and impartial. The mediator shall be disqualified as a witness, consultant, expert, or counsel for either party with respect to the matters in Dispute and any related matters. The Company Group and Employee shall pay their respective attorneys’ fee and other costs associated with the mediation, and the Company Group and Employee shall equally bear the costs and fees of the mediator. If a Dispute

cannot be resolved through mediation within ninety (90) days of being submitted to mediation, the parties agree to submit the Dispute to arbitration.

(b)Arbitration. Subject to Section 8(a), all Disputes will be submitted for binding arbitration to the American Arbitration Association on demand of either party. Such arbitration proceeding will be conducted in Wichita, Kansas and, except as otherwise provided in this Agreement, will be heard by one (1) arbitrator in accordance with the Commercial Arbitration Rules of the American Arbitration Association then in effect. All matters relating to arbitration will be governed by the Federal Arbitration Act (9 U.S.C. §§ 1 et seq.) and not by any state arbitration law. The arbitrator will have the right to award or include in his award any relief which he deems proper under the circumstances, including, without limitation, money damages (with interest on unpaid amounts from the date due), specific performance, injunctive relief, and reasonable attorneys’ fees and costs, provided that the arbitrator will not have the right to amend or modify the terms of this Agreement. The award and decision of the arbitrator will be conclusive and binding upon all parties hereto, and judgment upon the award may be entered in any court of competent jurisdiction. Except as specified above, the Company Group and Employee shall pay their respective attorneys’ fees and other costs associated with the arbitration, and the Company shall solely bear the costs and fees of the arbitrator. Nothing in this Section shall preclude Employee from filing a charge or complaint with a federal, state or other governmental administrative agency, and nothing herein will require the arbitration of claims that, as a matter of applicable law, the parties cannot agree to arbitrate.

(c)Confidentiality. Employee and the Company agree that they will not disclose, or permit those acting on their behalf to disclose, any aspect of the proceedings under Section 8(a) and Section 8(b), including but not limited to the resolution or the existence or amount of any award, to any person, firm, organization, or entity of any character or nature, unless divulged (i)to an agency of the federal or state government, (ii) pursuant to a court order, (iii) pursuant to a requirement of law, (iv) pursuant to prior written consent of the other party, or (v) pursuant to a legal proceeding to enforce a settlement agreement or arbitration award. This provision is not intended to prohibit nor does it prohibit Employee’s or the Company’s disclosures of the terms of any settlement or arbitration award to their attorney(s), accountant(s), financial advisor(s), or family members, provided that they comply with the provisions of this paragraph and the Company or Employee, as the case may be, shall be responsible for any non-compliance with this paragraph by persons to whom any such terms have been disclosed pursuant to this sentence.

(d)Injunctions. Notwithstanding anything to the contrary contained in this Section 8, the Company Group and Employee shall have the right in a proper case to obtain temporary restraining orders and temporary or preliminary injunctive relief from a court of competent jurisdiction; provided, however, that the Company Group and Employee must contemporaneously submit the Disputes for nonbinding mediation

under Section 8(a) and then for arbitration under Section 8(b) on the merits as provided herein if such Disputes cannot be resolved through mediation.

(e)THE PARTIES ACKNOWLEDGE THAT, IN ENTERING INTO THIS SECTION 8, THEY ARE KNOWINGLY AND VOLUNTARILY WAIVING THEIR RIGHTS TO A JURY TRIAL.

Section 9.General.

(a)Notices. All notices required or permitted under this Agreement shall be in writing, may be made by personal delivery or facsimile transmission, effective on the day of such delivery or receipt of such transmission, or may be mailed by registered or certified mail, effective two (2) days after the date of mailing, addressed as follows:

To Employee:

at Employee’s last known residence address or to such other address as designated by Employee in writing to the Company.

(b)Successors. Neither this Agreement nor any right or interest therein shall be assignable or transferable (whether by pledge, grant of a security interest, or otherwise) by Employee or Employee’s beneficiaries or legal representatives, except by will, by the laws of descent and distribution, or inter vivos revocable living grantor trust as Employee’s beneficiaries. This Agreement shall be binding upon and shall inure to the benefit of the Company, its successors and assigns, and Employee and shall be enforceable by them and Employee’s heirs, legatees, and legal personal representatives, provided that the Company may not assign this Agreement except to an acquirer of all or substantially all of its assets and then only if the assignee assumes the obligations hereunder in writing or operation of law. Holdings is an intended beneficiary of Employee’s covenants,

representations and warranties that are applicable to it and shall be entitled to enforce and rely upon such provisions.

(c)Waiver, Modification, and Interpretation. No provisions of this Agreement may be modified, waived, or discharged unless such waiver, modification, or discharge is agreed to in a writing signed by Employee and an appropriate officer of the Company empowered to sign the same by the Board. No waiver by either party at any time of any breach by the party of, or compliance with, any condition or provision of this Agreement to be performed by the other party shall be deemed a waiver of similar or dissimilar provisions or conditions at the same time or at any prior or subsequent time. The validity, interpretation, construction, and performance of this Agreement shall be governed by the laws of the State of Kansas; provided, however, that the corporate law of the state of incorporation of the Company’s parent shall govern issues related to the issuance of shares of its common stock. Except as provided in Section 8, any action brought to enforce or interpret this Agreement shall be maintained exclusively in the state and federal courts located in Wichita, Kansas.

(d)Interpretation. The headings contained herein are for reference purposes only and shall not in any way affect the meaning or interpretation of any provision of this Agreement. No provision of this Agreement shall be interpreted for or against any party hereto on the basis that such party was the draftsman of such provision; and no presumption or burden of proof shall arise disfavoring or favoring any party by virtue of the authorship of any of the provisions of this Agreement.

(e)Counterparts. The Company and Employee may execute this Agreement in any number of counterparts, each of which shall be deemed to be an original but all of which shall constitute but one instrument. In proving this Agreement, it shall not be necessary to produce or account for more than one such counterpart.

(f)Invalidity of Provisions. If a court of competent jurisdiction shall declare that any provision of this Agreement is invalid, illegal, or unenforceable in any respect, and if the rights and obligations of the Parties to this Agreement will not be materially and adversely affected thereby, in lieu of such illegal, invalid, or unenforceable provision the court may add as a part of this Agreement a legal, valid, and enforceable provision as similar in terms to such illegal, invalid, or unenforceable provision as is possible. If such court cannot so substitute or declines to so substitute for such invalid, illegal, or unenforceable provision, (i) such provision will be fully severable; (ii) this Agreement will be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part hereof; and (iii) the remaining provisions of this Agreement will remain in full force and effect and not be affected by the illegal, invalid, or unenforceable provision or by its severance herefrom. The covenants contained in this Agreement shall each be construed to be a separate agreement independent of any other provision of this Agreement, and the existence of any claim or cause of

action of Employee against the Company, predicated on this Agreement or otherwise, shall not constitute a defense to the enforcement by the Company of any of said covenants.

(g)Entire Agreement. This Agreement (together with the documents expressly referenced herein) constitutes the entire agreement between the parties, supersedes in all respects any prior agreement between the Company and Employee and may not be changed except by a writing duly executed and delivered by the Company and Employee in the same manner as this Agreement.

(h)No Mitigation. Employee shall not be required, as a condition to receiving any payments or benefits under this Agreement, to seek or obtain any other employment after any termination of employment hereunder or to take any steps to reduce the amount of any payment or benefit described in this Agreement. Further, the amount of any payment or benefit provided in this Agreement shall not be reduced by any compensation earned by Employee as the result of any employment by another employer or other compensation for services.

(i)Indemnity. The Company will indemnify Employee to the same extent the Company indemnifies other comparable level executives of the Company consistent with the Company’s Certificate of Incorporation and Bylaws.

(j)Excess Parachute Payments. If any portion of the payments or benefits under this Agreement, or under any other agreement with Employee or any plan of the Company or its affiliates (in the aggregate, “Total Payments”), would constitute an “excess parachute payment” and would, but for this paragraph, result in the imposition on Employee of an excise tax under Section 4999 of the Code (the “Excise Tax”), then the Total Payments to be made to Employee shall either be (i) delivered in full, or (ii) delivered in such amount so that no portion of such Total Payments would be subject to the Excise Tax, whichever of the foregoing results in the receipt by Employee of the greatest benefit on an after-tax basis (taking into account the applicable federal, state and local income taxes and the Excise Tax) and the reduction will be made in such manner that results in the maximum amount to be retained by Employee and is in compliance with Code sections 280G and 409A. The determination required by this paragraph shall be made by the Company in its reasonable determination and in reliance on its tax advisors.

Organization, Basis of Interim Presentation and Recent Developments

Unless the context otherwise indicates or requires, as used in this Quarterly Report on Form 10-Q, references to “we,” “us,” “our,” and the “Company” refer to Spirit AeroSystems Holdings, Inc. and its consolidated subsidiaries. References to “Spirit” refer only to our subsidiary, Spirit AeroSystems, Inc., and references to “Holdings” refer only to Spirit AeroSystems Holdings, Inc.

The Company provides manufacturing and design expertise in a wide range of fuselage, propulsion, and wing products and services for aircraft original equipment manufacturers (“OEM”) and operators through its subsidiaries including Spirit. The Company's headquarters are in Wichita, Kansas, with manufacturing and assembly facilities in Tulsa, Oklahoma; Prestwick, Scotland; Wichita, Kansas; Kinston, North Carolina; Subang, Malaysia; Saint-Nazaire, France; Biddeford, Maine; Woonsocket, Rhode Island; Belfast, Northern Ireland; Casablanca, Morocco; and Dallas, Texas.

The accompanying unaudited interim condensed consolidated financial statements include the Company’s financial statements and the financial statements of its majority-owned or controlled subsidiaries and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the instructions to Form 10-Q and Article 10 of Regulation S-X. The Company’s fiscal quarters are 13 weeks in length. Since the Company’s fiscal year ends on December 31, the number of days in the Company’s first and fourth quarters varies slightly from year to year. All intercompany balances and transactions have been eliminated in consolidation.

As part of the monthly consolidation process, the Company’s international subsidiaries that have functional currencies other than the U.S. dollar are translated to U.S. dollars using the end-of-month translation rate for balance sheet accounts and average period currency translation rates for revenue and income accounts. The subsidiaries in Prestwick, Scotland and Subang, Malaysia use the British pound as their functional currency. All other foreign subsidiaries and branches use the U.S. dollar as their functional currency.

In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements contain all adjustments (consisting of normal recurring adjustments and elimination of intercompany balances and transactions) considered necessary to fairly present the results of operations for the interim period. The results of operations for the nine months ended September 28, 2023, are not necessarily indicative of the results that may be expected for the year ending December 31, 2023.

In connection with the preparation of the condensed consolidated financial statements, the Company evaluated subsequent events through the date the financial statements were issued. The interim financial statements should be read in conjunction with the audited consolidated financial statements, including the notes thereto, included in the Company’s 2022 Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on February 17, 2023 (the “2022 Form 10-K”).

The Company's significant accounting policies are described in Note 3 Summary of Significant Accounting Policies to our consolidated financial statements in the 2022 Form 10-K.

Changes in Estimates [Abstract]

Change In Estimate [Text Block]

.  Changes in Estimates

The Company has a periodic forecasting process in which management assesses the progress and performance of the Company’s programs. This process requires management to review each program’s progress by evaluating the program schedule, changes to identified risks and opportunities, changes to estimated revenues and costs for the accounting contracts (and options if applicable), and any outstanding contract matters. Risks and opportunities include but are not limited to management’s judgment about the cost associated with the Company’s ability to achieve the schedule, technical requirements (e.g., a newly-developed product versus a mature product), and any other program requirements. Due to the span of years it may take to completely satisfy the performance obligations for the accounting contracts (and options, if any) and the scope and nature of the work required to be performed on those contracts, the estimation of total revenue and costs is subject to many variables and, accordingly, is subject to change based upon judgment. The Company’s estimate of costs depends on maintaining continuing, uninterrupted production at its manufacturing facilities and its suppliers’ facilities. The continued fragility of the global aerospace supply chain may lead to interruptions in deliveries of or increased prices for components or raw materials used in the Company's products, labor disruptions, and could delay production and/or materially adversely affect the Company's business. When adjustments in estimated total consideration or estimated total cost are required, any changes from prior estimates for fully satisfied performance obligations are recognized in the current period as a cumulative catch-up adjustment for the inception-to-date effect of such changes. Cumulative catch-up adjustments are driven by several factors including production efficiencies, assumed rate of production, the rate of overhead absorption, changes to scope of work, and contract modifications. Cumulative catch-up adjustments are primarily related to changes in the estimated margin of contracts with performance obligations that are satisfied over time.

Changes in estimates could materially adversely affect the Company’s future financial performance. While certain increases in raw material costs can generally be passed on to the Company’s customers, in most instances the Company must fully absorb cost overruns. Some of the factors that may cause the costs incurred in fulfilling contracts to vary substantially from current estimates are technical problems, production rate changes, production stoppages, materials shortages, supplier difficulties, realization targets, existence of and execution to recovery plans caused by these factors, and multiple other events, including those identified in Item 1A. “Risk Factors” of the 2022 Form 10-K. The risk particularly applies to products such as the B787, A220, and A350, which are in forward loss positions.

During the third quarter ended September 28, 2023, the Company recognized unfavorable changes in estimates of $165.1, which included net forward loss charges of $101.1, and unfavorable cumulative catch-up adjustments related to periods prior to the third quarter of 2023 of $64.0. The forward losses in the third quarter were primarily driven by labor and production cost growth on the A350 program, additional labor and supply chain cost growth on the B787 program, increased factory performance and supply chain costs on the B767 program, and production costs incurred on the Sikorsky CH-53K program. The unfavorable cumulative catch-up adjustments primarily relate to increased factory performance costs and rework costs related to the quality issue on the B737 aft pressure bulkhead on the B737 program, and production cost overruns and foreign currency movements on the A320 program.

During the third quarter ended September 29, 2022, the Company recognized unfavorable changes in estimates of $54.0, which included net forward loss charges of $49.1, and unfavorable cumulative catch-up adjustments related to periods prior to the third quarter of 2022 of $4.9. The forward losses in the quarter ended September 29, 2022 were primarily driven by losses on the A350, B787, and RB3070 programs. Increased cost estimates for production on the A350 program resulted in a forward loss reflecting additional labor, freight, and other cost requirements driven by parts shortages and production and quality issues. The B787 program forward loss was driven by increased cost estimates for supply chain, rework, and fixed cost absorption. The

RB3070 nacelle program forward loss was driven by increased engineering cost estimates. The unfavorable cumulative catch-up adjustments primarily relate to adjustments for production schedule changes and increased costs on the A320 program.

.  Accounts Receivable and Allowance for Credit Losses

Accounts Receivable, net

Accounts receivable represent the Company’s unconditional rights to consideration, subject to the payment terms of the contract, for which only the passage of time is required before payment. Unbilled receivables are reflected under contract assets on the Condensed Consolidated Balance Sheets. See also Allowance for Credit Losses, below.

Accounts receivable, net consists of the following:

	September 28, 2023		December 31, 2022
Trade receivables	$	579.4	$	477.9
Other	43.8		19.7
Less: allowance for credit losses	(12.9)		(8.1)
Accounts receivable, net	$	610.3	$	489.5

The Company has agreements (through its subsidiaries) to sell, on a revolving basis, certain trade accounts receivable balances with Boeing, Airbus Group SE and its affiliates (collectively, “Airbus”), and Rolls-Royce PLC and its affiliates (collectively, “Rolls-Royce”) to third-party financial institutions. These programs were primarily entered into as a result of customers seeking payment term extensions with the Company and they continue to allow the Company to monetize the receivables prior to their payment date, subject to payment of a discount. No guarantees are delivered under the agreements. The Company's ability to continue using such agreements is primarily dependent upon the strength of the applicable customer’s financial condition. Transfers under these agreements are accounted for as sales of receivables resulting in the receivables being

derecognized from the Company's Condensed Consolidated Balance Sheets. For the nine months ended September 28, 2023, $2,657.0 of accounts receivable were sold via these arrangements. The proceeds from these sales of receivables are included in cash from operating activities in the Condensed Consolidated Statements of Cash Flows. The recorded net loss on sale of receivables was $36.5 for the nine months ended September 28, 2023 and is included in other income and expense. See Note 21 Other Income (Expense), Net.

Allowance for Credit Losses

During the nine months ended September 28, 2023, there have been no significant changes in the factors that influenced management’s current estimate of expected credit losses, nor changes to the Company’s accounting policies or Current Expected Credit Losses methodology. The beginning balances, current period activity, and ending balances of the allocation for credit losses on accounts receivable and contract assets were not material.

Revenue from Contract with Customer [Abstract]

contract with customer, asset and liability [Text Block]

Contract Assets and Contract Liabilities

Contract assets primarily represent revenues recognized for performance obligations that have been satisfied but for which amounts have not been billed. Contract assets, current are those that are expected to be billed to our customer within 12 months. Contract assets, long-term are those that are expected to be billed to our customer over periods greater than 12 months. No impairments to contract assets were recorded for the period ended September 28, 2023 or the period ended September 29, 2022. See also Note 5 Accounts Receivable and Allowance for Credit Losses.

Contract liabilities are established for cash received in excess of revenues recognized and are contingent upon the satisfaction of performance obligations. Contract liabilities primarily consist of cash received on contracts for which revenue has been deferred since the receipts are in excess of transaction price resulting from the allocation of consideration based on relative standalone selling price to future units (including those under option that the Company believes are likely to be exercised) with prices that are lower than standalone selling price. These contract liabilities will be recognized earlier if the options are not fully exercised, or immediately, if the contract is terminated prior to the options being fully exercised.

	September 28, 2023		December 31, 2022		Change
Contract assets	$	616.9	$	502.2	$	114.7
Contract liabilities	(352.8)		(356.4)		3.6
Net contract assets (liabilities)	$	264.1	$	145.8	$	118.3

For the period ended September 28, 2023, the increase in contract assets reflects the net impact of more over time revenue recognition in relation to billed revenues during the period. The decrease in contract liabilities reflects the net impact of less deferred revenues recorded in excess of revenue recognized during the period. The Company recognized $66.4 of revenue that was included in the contract liability balance at the beginning of the period.

	September 29, 2022		December 31, 2021		Change
Contract assets	$	547.4	$	443.2	$	104.2
Contract liabilities	(361.7)		(387.0)		25.3
Net contract assets (liabilities)	$	185.7	$	56.2	$	129.5

For the period ended September 29, 2022, the increase in contract assets reflects the net impact of more over time revenue recognition in relation to billed revenues during the period. The decrease in contract liabilities reflects the net impact of less deferred revenues recorded in excess of revenue recognized during the period. The Company recognized $63.2 of revenue that was included in the contract liability balance at the beginning of the period.

Inventory Disclosure [Abstract]

Inventory

Inventory

Inventory consists of raw materials used in the production process, work-in-process, which is direct material, direct labor, overhead and purchases, and capitalized pre-production costs. Raw materials are stated at lower of cost (principally on an actual or average cost basis) or net realizable value. Capitalized pre-production costs include certain contract costs, including applicable overhead, incurred before a product is manufactured on a recurring basis. These costs are typically amortized over a period that is consistent with the satisfaction of the underlying performance obligations to which these relate.

	September 28, 2023		December 31, 2022
Raw materials	$	395.4	$	332.7
Work-in-process(1)	1,226.2		1,044.9

Product inventory	1,668.4		1,447.0
Capitalized pre-production	21.6		23.7
Total inventory, net	$	1,690.0	$	1,470.7

(1)Work-in-process inventory includes direct labor, direct material, overhead, and purchases on contracts for which revenue is recognized at a point in time as well as sub-assembly parts that have not been issued to production on contracts for which revenue is recognized over time using an input method. For the periods ended September 28, 2023 and December 31, 2022, work-in-process inventory includes $256.3 and $392.2, respectively, of costs incurred in anticipation of specific contracts and no impairments were recorded in the periods.

Product inventory, summarized in the table above, is shown net of valuation reserves of $148.3 and $136.8 as of September 28, 2023 and December 31, 2022, respectively.

Excess capacity and abnormal production costs are excluded from inventory and recognized as expense in the period incurred. Cost of sales for the three and nine months ended September 28, 2023 includes period expense of $56.4 and $152.9, respectively, for excess capacity production costs related to temporary B737 MAX, A320 and A220 production schedule changes, and abnormal production costs of $0.8 and $8.1, respectively, related to the temporary production pause.

Leases [Abstract]

Leases of Lessee Disclosure [Text Block]

The Company determines if an arrangement is a lease at the inception of a signed agreement. Operating leases are included in right-of-use (“ROU”) assets (long-term), short-term operating lease liabilities, and long-term operating lease liabilities on the Company’s Condensed Consolidated Balance Sheets. Finance leases are included in Property, Plant and Equipment, current maturities of long-term debt, and long-term debt.

ROU assets represent the right of the Company to use an underlying asset for the length of the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term.

To determine the present value of lease payments, the Company uses its estimated incremental borrowing rate or the implicit rate, if readily determinable. The estimated incremental borrowing rate is based on information available at the lease commencement date, including any recent debt issuances and publicly available data for instruments with similar characteristics. The ROU asset also includes any lease payments made and excludes lease incentives.

The Company's lease terms may include options to extend or terminate the lease and, when it is reasonably certain that an option will be exercised, those options are included in the net present value calculation. Leases with a term of 12 months or less, which are primarily related to automobiles and manufacturing equipment, are not recorded on the Condensed Consolidated Balance Sheets. The aggregate amount of lease cost for leases with a term of 12 months or less is not material.

The Company has lease agreements that include lease and non-lease components, which are generally accounted for separately. For certain leases (primarily related to IT equipment), the Company does account for the lease and non-lease components as a single lease component. A portfolio approach is applied to effectively account for the ROU assets and liabilities for those specific leases referenced above. The Company does not have any material leases containing variable lease payments or residual value guarantees. The Company also does not have any material subleases.

The Company currently has operating and finance leases for items such as manufacturing facilities, corporate offices, manufacturing equipment, transportation equipment, and vehicles. The majority of the Company's active leases have remaining lease terms that range between less than one year to 15 years, some of which include options to extend the leases for up to 30 years, and some of which include options to terminate the leases within one year.

Advance Payments And Deferred Revenue Credits [Abstract]

Advance Payments

Advance Payments

Advances on the B787 Program.  Boeing has made advance payments to Spirit under the B787 Special Business Provisions and General Terms Agreement (collectively, the “B787 Supply Agreement”) that are required to be repaid to Boeing by way of offset against the purchase price for future shipset deliveries. Advance repayments were initially scheduled to be spread evenly over the remainder of the first 1,000 B787 shipsets delivered to Boeing. On April 8, 2014, Spirit signed a memorandum of agreement with Boeing that suspended advance repayments related to the B787 program for a period of twelve months beginning April 1, 2014. Repayment recommenced on April 1, 2015, and any repayments that otherwise would have become due during such twelve-month period will offset the purchase price for shipsets 1001 through 1120. On December 21, 2018, Spirit signed a memorandum of agreement with Boeing that again suspended the advance repayments beginning with line unit 818. The advance repayments will resume at a lower rate of $0.45 per shipset at line number 1135 and continue through line number 1605.

In the event Boeing does not take delivery of a sufficient number of shipsets to repay the full amount of advances prior to the termination of the B787 program or the B787 Supply Agreement, any advances not then repaid will be applied against any outstanding payments then due by Boeing to us, and any remaining balance will be repaid in annual installments of $27 due on December 15th of each year until the advance payments have been fully recovered by Boeing. As of September 28, 2023, the

amount of advance payments received from Boeing under the B787 Supply Agreement and not yet repaid was approximately $194.5.

Advances on the B737 Program. In an effort to minimize the disruption to Spirit's operations and its supply chain, Spirit and Boeing entered into a Memorandum of Agreement on April 12, 2019 (the “2019 MOA”), which included the terms and conditions for an advance payment to be made from Boeing to Spirit in the amount of $123.0, which was received during the third quarter of 2019. Spirit and Boeing entered into a Memorandum of Agreement on February 6, 2020, which extended the repayment date of the $123.0 advance received by Spirit under the 2019 MOA to 2022. $0.0 and $92.3 of advance payments received from Boeing were repaid in the nine months ended September 28, 2023 and September 29, 2022, respectively. There was no balance due as of September 28, 2023.

Advances on the A350 Program. During the three months ended June 29, 2023, the Company received an advance payment from Airbus of $50.0 under an agreement between Airbus S.A.S. and Spirit AeroSystems (Europe) Limited (“Spirit Europe”) signed on June 23, 2023 (the “A350 Agreement”). During the three months ended September 28, 2023, the Company received a second advance payment from Airbus of $50.0. These advances are required to be repaid along with a nominal fee to Airbus by way of offset against the purchase price of A350 FLE shipset deliveries in 2025. To the extent actual deliveries in 2025 are insufficient to offset the advance amount, any amount not offset against deliveries will be due and payable to Airbus on December 31, 2025. In connection with the A350 Agreement, Spirit Europe has pledged certain program assets including work in process inventories and raw materials at Spirit's Scotland facility in an amount sufficient to cover the advances.

Other. The Advance payments, long-term line item on the Condensed Consolidated Balance Sheets for the period ended September 28, 2023 includes $18.9 related to payments received from an Aftermarket segment customer for contracted work that was impacted by the sanctions imposed by the U.S. and other governments on Russia following its invasion of Ukraine.

Fair Value Disclosures [Abstract]

Fair Value Measurements

Fair Value Measurements

The FASB’s authoritative guidance on fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. It also establishes a fair value hierarchy, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The guidance discloses three levels of inputs that may be used to measure fair value:

Level 1 Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 1 assets and liabilities include debt and equity securities and derivative contracts that are traded in an active exchange market.

Level 2                      Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments and derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. Observable inputs, such as current and forward interest rates and foreign exchange rates, are used in determining the fair value of the interest rate swaps and foreign currency hedge contracts.

Level 3                 Unobservable inputs that are supported by little or no market activity and are significant to the fair value of assets and liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

At September 28, 2023, the Company’s long-term debt includes a senior secured term loan and senior notes described further under Note 15 Debt. The estimated fair value of the Company’s debt obligations is based on the quoted market prices for such obligations or the historical default rate for debt with similar credit ratings. The following table presents the carrying amount and estimated fair value of long-term debt. See also Note 14 Derivative and Hedging Activities and Note 16 Pension and Other Post-Retirement Benefits.

Derivative and Hedging Activities

Derivatives Accounted for as Hedges

Cash Flow Hedges – Foreign Currency Forward Contract

The Company has entered into currency forward contracts, each designated as a cash flow hedge upon the date of execution, for the purpose of reducing the variability of cash flows and hedging against the foreign currency exposure for forecasted payroll, pension and vendor disbursements that are expected to be made in the British Pound Sterling. The hedging program implemented is intended to reduce foreign currency exposure, and the associated forward currency contracts hedge forecasted transactions through June 2024.

The following table summarizes the notional amounts (representing the gross contract/notional amount of the derivatives outstanding) and fair values of the derivative instruments in the Condensed Consolidated Balance Sheets as of September 28, 2023, and December 31, 2022. The foreign currency exchange contracts are measured within Level 1 of the Fair Value hierarchy. See Note 13 Fair Value Measurements.

	Notional amount				Other assets				Other liabilities
	September 28, 2023		December 31, 2022		September 28, 2023		December 31, 2022		September 28, 2023		December 31, 2022

Total derivatives at fair value					$	—	$	—	$	6.3	$	2.4

Changes in the fair value of cash flow hedges are recorded in AOCI and recorded in earnings in the period in which the hedged transaction settles. The gain (loss) recognized in AOCI associated with our hedging transactions is presented in the following table:

	Three Months Ended				Nine Months Ended

Foreign currency exchange contracts:
Other income (expense)	$	3.8	$	(6.5)	$	1.7	$	(12.1)

Within the next 12 months, the Company expects to recognize a loss of ($6.3) in earnings related to the foreign currency forward contracts. As of September 28, 2023, the maximum term of the hedged forecasted transaction was 9 months. Generally, the Company has agreements with its counterparties that contain a provision whereby if the Company defaults on its existing credit facilities and payment of the loans extended under such facilities is accelerated, the Company could be declared in default under its agreements, which may result in the early termination of the outstanding derivatives governed by such agreements and the payment of an early termination amount.

Derivatives Not Accounted for as Hedges

During the nine months ended September 28, 2023, all foreign currency forward contracts were designated as hedges, and the Company applied hedge accounting to all foreign currency forward contracts.

During the nine months ended September 29, 2022, the Company entered into foreign currency forward contracts in the amount of $291.5 to minimize the risk of currency exchange rate movements on the Company's planned settlement of the repayable investment agreement between the Company and the U.K.'s Department for Business, Energy and Industrial Strategy. During the nine-month period ended September 29, 2022, these foreign currency forward contracts were settled, and new contracts were entered into in the amount of $293.7, which were also settled during the period. The Company did not designate these forward contracts as hedges or apply hedge accounting to the forward contracts. For the nine months ended September 29, 2022, the Company recorded a net gain of $1.6 to other income on the Condensed Consolidated Statements of Operations related to the foreign currency forward contracts.

(1)    In July 2022, the Company adopted and communicated to participants a plan to terminate the Company's Pension Value Plan A (“PVP A”). As further described in the Company's 2021 Form 10-K, the PVP A consists of pension plans which were frozen as of the date Holdings became a standalone company and commenced operations. During the three months ended September 29, 2022, the PVP A plan was amended, providing for an enhancement to benefits the Company is providing to certain U.S. employees in conjunction with the plan termination. The estimated liability impact of this plan amendment, $71.7, was recognized immediately as a non-cash, pre-tax non-operating charge for amortization of prior service costs.

(2) Includes a $64.6 settlement charge for the PVP A during the nine months ended September 28, 2023. Includes a $0.9 settlement charge for the PVP A during the three months ended September 29, 2022, and a ($1.4) settlement credit for PVP B related to final asset distribution in the nine months ended September 29, 2022.

The components of net periodic pension expense (income) and other benefit income, other than the service cost component, are included in Other income (expense), net in the Company's Condensed Consolidated Statements of Operations. See Note 21 Other Income (Expense), Net.

As disclosed in the Company's 2022 Form 10-K, effective October 1, 2021, the Company spun off a portion of the existing PVP A, to a new plan called PVP B (“PVP B”). As part of the PVP B plan termination process, a lump sum offering was provided during 2021 for PVP B participants and the final asset distribution was completed in the first quarter of 2022. At September 28, 2023, a pension reversion asset of $61.4 is recorded on the Restricted plan assets line item on the Company’s Condensed Consolidated Balance Sheets. Restricted plan assets are expected to be reduced over the next six years as they are

distributed to employees under a qualified compensation and benefit program. Restricted plan assets are valued at fair value with gain or loss on fair value adjustments recognized within other income. The underlying investments' fair value measurement levels under the FASB's authoritative guidance on fair value measurements are Level 2, see Note 13 Fair Value Measurements.

Separately, during the nine months ended September 28, 2023, the Company received an excess plan asset reversion of $179.5 of cash from PVP A. During the nine months ended September 29, 2022, the Company withdrew $34.0 of cash from PVP B, which represented an excess plan assets reversion. These transactions were accounted for as a negative contribution and are included on the Pension plans employer contributions line item on the Condensed Consolidated Statements of Cash Flows for the nine months ended September 28, 2023 and September 29, 2022. Excise tax of $35.9 and $6.8 related to the reversion of excess plan assets was separately recorded to the Other income (expense), net line item on the Company's Condensed Consolidated Statements of Operations for the nine months ended September 28, 2023 and September 29, 2022, respectively. See also Note 21 Other Income (Expense), Net.

As disclosed in the Company's 2022 Form 10-K, in July 2022, the Company adopted and communicated to participants a plan to terminate the PVP A. During the nine months ended September 28, 2023, the Company recognized non-cash, pre-tax non-operating accounting charges of $64.6 related to the plan termination, primarily reflecting the accounting for a group annuity purchase made in the first quarter of 2023, which resulted in a settlement charge related to the accelerated recognition of the actuarial losses for the PVP A plan that were previously included in the Accumulated other comprehensive loss line item in the Stockholders' Equity section of the Company's Condensed Consolidated Balance Sheets.

In connection with the special accounting related to the termination of the PVP A plan, discussed above, a subsequent interim measurement of the Company's U.S. pension and other postretirement plan assets and obligations was completed during the three months ended September 29, 2022. The interim measurement, including the estimated impact of the plan termination liability and enhanced benefits liability noted above, prior to the current period settlement loss and amortization of prior service cost impacts included in Net Periodic Pension Expense above, was recorded to the Accumulated other comprehensive loss line item in the Stockholders' Equity section of the Company's Condensed Consolidated Balance Sheet for the period ended September 29, 2022.

Employer Contributions

Other than the reversion of excess plan assets noted above, which was accounted for as a negative contribution, the Company's expected contributions for the current year have not significantly changed from those described in the Company's 2022 Form 10-K.

Stock Compensation

Stock Compensation

Holdings has established the stockholder-approved Amended and Restated 2014 Omnibus Incentive Plan (the “Omnibus Plan”), to grant cash and equity awards of Holdings' Class A Common Stock, par value $0.01 per share (the “Common Stock”), to certain individuals. Holdings has established the Long-Term Incentive Plan (the “LTIP”) under the Omnibus Plan to grant equity awards to certain employees of the Company.

The Company recognized a net total of $8.6 and $10.4 of stock compensation expense for the three months ended September 28, 2023 and September 29, 2022, respectively, and a net total of $27.8 and $28.7 of stock compensation expense for the nine months ended September 28, 2023 and September 29, 2022, respectively.

During the nine months ended September 28, 2023, 560,190 time or service-based restricted stock units (“RSUs”) were granted with an aggregate date fair values of $18.8 under the Company's LTIP. Awards vest over a three-year period, beginning on the date of grant. Values for these awards are based on the value of Common Stock on the grant date.

During the nine months ended September 28, 2023, 231,927 performance-based restricted stock units (“PBRSUs”) were granted with an aggregate grant date fair value of $12.0 under the Company’s LTIP. These awards are earned based on Holdings’ total shareholder return relative to its peer group over a three-year performance period. Values for these awards are initially measured on the grant date using the estimated payout levels derived from a Monte Carlo valuation model.

During the nine months ended September 28, 2023, 116,006 PBRSUs were granted with an aggregate grant date fair value of $4.0 under the Company’s LTIP. These awards are earned based on pre-established 2024 - 2025 free cash flow goals. Values for these awards are based on the dividend adjusted value of Common Stock on the grant date.

During the nine months ended September 28, 2023, 116,006 PBRSUs were granted with an aggregate grant date fair value of $4.0 under the Company’s LTIP. These awards are earned based on pre-established goals of revenue growth over a three-year performance period. Values for these awards are based on the dividend adjusted value of Common Stock on the grant date.

During the nine months ended September 28, 2023, 42,065 shares of restricted Common Stock and 39,005 non-employee director restricted stock units (“DRSUs”) were granted to the Board of Directors of the Company (the “Board”) with an aggregate grant date fair value of $2.0. Both types of awards vest if the non-employee director remains continuously in service for the entire one-year term to which the grant relates. If the non-employee director incurs a termination for any reason before the end of the term (before the annual meeting of stockholders following the grant), the awards are forfeited. Upon vesting, shares relating to restricted Common Stock awards are delivered to the director free of restriction; however, vested shares of Common Stock underlying DRSUs are not delivered to the director until the date that the director leaves the Board. Values for these awards are based on the value of Common Stock on the grant date.

During the nine months ended September 28, 2023, 466,597 shares of Common Stock with an aggregate grant date value of $22.5 vested under the Company's LTIP. Additionally, 41,096 shares of Common Stock previously granted to the Board vested with an aggregate grant date fair value of $1.3, and 22,155 DRSUs previously awarded to the Board vested with an aggregate grant date fair value of $0.7.

The Company maintains the Spirit AeroSystems Holdings, Inc. Employee Stock Purchase Plan (the “ESPP”) which became effective on October 1, 2017 and was amended and restated on October 21, 2022. Under the amended plan, the per-share purchase price for the Company's Common stock purchased under the ESPP is 85% of the lower of (a) the fair market value of a share on the first day of the applicable offering period or (b) the fair market value of a share on the applicable purchase date.

The Company recognized $0.9 and $1.5 of stock compensation expense related to the ESPP for the three and nine months ended September 28, 2023. The Company recognized no stock compensation expense related to the ESPP for the three and nine months ended September 29, 2022.

Income Taxes

The process for calculating the Company’s income tax expense involves estimating actual current taxes due plus assessing temporary differences arising from differing treatment for tax and accounting purposes that are recorded as deferred tax assets and liabilities. Deferred tax assets are periodically evaluated to determine their recoverability and whether a valuation allowance is necessary.

A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. When determining the amount of net deferred tax assets that are more likely than not to be realized, the Company assesses all available positive and negative evidence. The weight given to the positive and negative evidence is commensurate with the extent the evidence may be objectively verified. As such, it is generally difficult for positive evidence regarding projected future taxable income exclusive of reversing taxable temporary differences to outweigh objective negative evidence of recent financial reporting losses.

Based on these criteria and the relative weighting of both the positive and negative evidence available, and in particular the activity surrounding our prior earnings history, including the forward losses previously recognized in the U.S., the Company has recorded a valuation allowance against U.S. deferred tax assets. Increases in the valuation allowances recorded against U.S. deferred tax assets in the nine months ended September 28, 2023 were $112.6. This is comprised of ($0.4) related to other comprehensive income (“OCI”) and $113.0 from continuing operations. As of September 28, 2023, the total net U.S. deferred tax asset before the valuation allowance was $544.9 and the total net U.S. valuation allowance was $547.7. The net U.S. deferred tax liability after valuation allowances was $2.8.

The Company has determined a valuation allowance on certain U.K. deferred tax assets is needed based upon cumulative losses generated in the U.K. Increases in the valuation allowances recorded against U.K. deferred tax assets in the nine-month period ended September 28, 2023 were $46.9. This is comprised of $0.0 related to other comprehensive income (“OCI”) and $46.9 from continuing operations, including utilization of net operating losses. As of September 28, 2023, the total net U.K. deferred tax asset before the valuation allowance was $322.1 and the total net U.K. valuation allowance was $326.2. The net U.K. deferred tax liability after valuation allowance was $4.1.

The Company files income tax returns in all jurisdictions in which it operates. The Company establishes reserves to provide for additional income taxes that may be due upon audit. These reserves are established based on management’s assessment as to the potential exposure attributable to permanent tax adjustments and associated interest. All tax reserves are analyzed quarterly and adjustments made as events occur that warrant modification.

In general, the Company records income tax expense each quarter based on its estimate as to the full year’s effective tax rate. Certain items, however, are given discrete period treatment and the tax effects for such items are therefore reported in the quarter that an event arises. Events or items that may give rise to discrete recognition include excess tax benefits with respect to share-based compensation, finalizing amounts in income tax returns filed, finalizing audit examinations for open tax years, expiration of statutes of limitations, and changes in tax law.

The (0.16%) effective tax rate for the nine months ended September 28, 2023 differs from the (6.49%) effective tax rate for the same period of 2022 primarily due to changes in the valuation allowances recorded on U.S. and U.K. deferred tax assets, nondeductible interest expense and nondeductible excise tax. As the Company is currently reporting a pre-tax loss for the nine months ended September 28, 2023, an increase in the effective tax rate results in an increase of income tax benefits while a decrease in the rate results in a reduction of income tax benefits.

As allowed by the Coronavirus Aid, Relief, and Economic Security Act, the Company has filed a claim for a pre-tax employee retention credit of $18.8 for 2020 and $1.0 for 2021. The outstanding pre-tax employee retention credit refund claim as of September 28, 2023 is $2.2.

The Company's federal audit is conducted under the Internal Revenue Service Compliance Assurance Process (“CAP”) program and is essentially complete for the 2020 tax year. The Company will continue to participate in the CAP program for 2021 through 2023. The CAP program's objective is to resolve issues in a timely, contemporaneous manner and eliminate the need for a lengthy post-filing examination. The Company has an open tax audit in the Kingdom of Morocco for tax years ending prior to the Company's ownership of the Moroccan legal entity. There are ongoing audits in other jurisdictions that are not material to the financial statements and the Company believes appropriate provisions for all outstanding tax issues have been made for all jurisdictions and years.

On July 11, 2023, the U.K. Finance Bill 2023 Number 2, also known as the Spring Finance Bill 2023, received Royal Assent. This legislation is effective for periods beginning after December 31, 2023 and has no impact on the current financial statements.

Earnings per Share Calculation

Basic net income per share is computed using the weighted-average number of outstanding shares of Common Stock during the measurement period. Diluted net income per share is computed using the weighted-average number of outstanding shares of Common Stock and, when dilutive, potential outstanding shares of Common Stock during the measurement period. Diluted earnings per share includes any dilutive impact of service-based restricted stock units, director restricted stock units, restricted stock awards, and performance-based restricted stock units.

The Company accounts for treasury stock under the cost method and includes treasury stock as a component of stockholders’ equity. As of September 28, 2023, no treasury shares have been reissued or retired.

The total authorization amount remaining under the current share repurchase program is approximately $925.0. During the nine-month period ended September 28, 2023, the Company did not repurchase any shares of its Common Stock under this

share repurchase program. Share repurchases are currently on hold. The Credit Agreement imposes restrictions on the Company’s ability to repurchase shares.

The following table sets forth the computation of basic and diluted earnings per share:

	For the Three Months Ended
	September 28, 2023					September 29, 2022
	Income		Shares	Per Share Amount		Income		Shares	Per Share Amount

Included in the outstanding Common Stock were 0.1 million and 0.4 million of issued but unvested shares at September 28, 2023 and September 29, 2022, respectively, which are excluded from the basic Earnings Per Share (“EPS”) calculation.

Shares of Common Stock of 0.6 million and 0.7 million, respectively, were excluded from diluted EPS as a result of incurring a net loss for the three and nine months ended September 28, 2023, as the effect would have been antidilutive. Additionally, diluted EPS for the three and nine months ended September 28, 2023 excludes 0.2 million shares that may be dilutive shares of Common Stock in the future but were not included in the computation of diluted EPS because the effect was either antidilutive or the performance condition was not met.

Shares of Common Stock of 0.5 million and 0.6 million, respectively, were excluded from diluted EPS as a result of incurring a net loss for the three and nine months ended September 29, 2022, as the effect would have been antidilutive. Additionally, diluted EPS for the three and nine months ended September 29, 2022 excludes 0.3 million shares that may be dilutive shares of Common Stock in the future but were not included in the computation of diluted EPS because the effect was either antidilutive or the performance condition was not met.

Accumulated Other Comprehensive Loss

Accumulated Other Comprehensive Loss is summarized by component as follows:

Litigation

On February 10, 2020, February 24, 2020, and March 24, 2020, three separate private securities class action lawsuits were filed against the Company in the U.S. District Court for the Northern District of Oklahoma, its former Chief Executive Officer, Tom Gentile III, former Chief Financial Officer, Jose Garcia, and former Controller (principal accounting officer), John Gilson. On April 20, 2020, the Class Actions were consolidated by the court (the “Consolidated Class Action”), and on July 20, 2020, the plaintiffs filed a Consolidated Class Action Complaint which added Shawn Campbell, the Company’s former Vice President for the B737NG and B737 MAX program, as a defendant. Allegations in the Consolidated Class Action include (i) violations of Section 10(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and Rule 10b-5 promulgated thereunder against the Company and Messrs. Gentile, Garcia, and Gilson, (ii) violations of Section 20(a) of the Exchange Act against the individual defendants, and (iii) violations of Section 10(b) of the Exchange Act and Rule 10b-5(a) and (c) promulgated thereunder against all defendants.

On June 11, 2020, a shareholder derivative lawsuit (the “Derivative Action 1”) was filed against the Company (as nominal defendant), all members of the Company’s then serving Board of Directors, and Messrs. Garcia and Gilson in the U.S. District Court for the Northern District of Oklahoma. Allegations in the Derivative Action 1 include (i) breach of fiduciary duty, (ii) abuse of control, and (iii) gross mismanagement. On October 5, 2020, a shareholder derivative lawsuit (the “Derivative Action 2” and, together with Derivative Action 1, the “Derivative Actions”) was filed against the Company (as nominal defendant), all then serving members of the Company’s Board of Directors, and Messrs. Garcia and Gilson in the Eighteenth Judicial District, District Court of Sedgwick County, Kansas. Allegations in the Derivative Action 2 include (i) breach of fiduciary duty, (ii) waste of corporate assets, and (iii) unjust enrichment. The Company and the individual defendants have denied, and continue to deny, the allegations in the Derivative Actions.

The facts underlying the Consolidated Class Action and Derivative Actions relate to the accounting process compliance independent review (the “Accounting Review”) discussed in the Company’s January 30, 2020 press release and described under Management's Discussion and Analysis of Financial Condition and Results of Operations - Accounting Review in Part II, Item 7 of the Annual Report on Form 10-K for the year ended December 31, 2019, and its resulting conclusions. The Company voluntarily reported to the SEC the determination that, with respect to the third quarter of 2019, the Company did not comply with its established accounting processes related to potential third quarter contingent liabilities received after the quarter-end. On March 24, 2020, the Staff of the SEC Enforcement Division informed the Company that it had determined to close its inquiry without recommending any enforcement action against the Company. In addition, the facts underlying the Consolidated Class Action and Derivative Actions relate to the Company’s disclosures regarding the B737 MAX grounding and Spirit’s production rate (and related matters) after the grounding.

On September 18, 2020, the Company and individual defendants filed a motion to dismiss the Consolidated Class Action. That motion was granted by the U.S. District Court on January 7, 2022, which denied leave to amend and dismissed the Consolidated Class Action with prejudice. On February 4, 2022, the plaintiffs in the Consolidated Class Action appealed this

decision to the Tenth Circuit Court of Appeals (the “Appellate Court”). On August 21, 2023, the Appellate Court affirmed the dismissal of the Consolidated Class Action. The Derivative Actions remain stayed at this point.

On May 3, 2023, a private securities class action lawsuit was filed in the U.S. District Court for the Southern District of New York against the Company, its former Chief Executive Officer, Tom Gentile III, and its Senior Vice President and Chief Financial Officer, Mark J. Suchinski. The lawsuit was brought on behalf of certain purchasers of securities of the Company, who allege purported misstatements and omissions concerning alleged faulty production controls and the alleged incorrect installation of fittings on certain B737 MAX planes (the “Securities Class Action”). The specific claims in the Securities Class Action include (i) violations of Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder against all defendants, and (ii) violations of Section 20(a) of the Exchange Act against the individual defendants. Lead plaintiff and counsel in the Securities Class Action were appointed on October 20, 2023. The Company believes that the claims in this lawsuit are without merit and intends to defend against them vigorously.

Spirit is also involved in litigation in the Appellate Court with its former Chief Executive Officer, Larry Lawson over Lawson's disputed violation of a restrictive covenant in his retirement and consulting agreement. On October 19, 2021, the U.S. District Court for the District of Kansas (the “District Court”) ruled in favor of Lawson and awarded him $44.8 for benefits withheld in connection with the disputed violation, as well as post-judgment interest at the rate of 4.25%. Spirit appealed the judgment to the Appellate Court. On February 27, 2023, the Appellate Court issued an opinion reversing the District Court decision and concluding that Lawson had violated the terms of the restrictive covenant and remanded for the District Court to address whether the restrictive covenant that Lawson violated was enforceable under Kansas law. On June 15, 2023, the District Court held that the restrictive covenant was enforceable as a matter of Kansas law. The District Court entered judgment in favor of Spirit on June 27, 2023. Lawson has appealed the District Court’s latest decision, and filed his opening appellate brief before the Appellate Court on October 20, 2023. Spirit will continue to defend its position vigorously on appeal. A liability for the full amount of the award issued on October 19, 2021, plus accrued interest through March 28, 2023, was recognized and remains accrued in the Condensed Consolidated Balance Sheets as of December 31, 2022 and September 28, 2023.

From time to time, in the ordinary course of business and similar to others in the industry, the Company receives requests for information from government agencies in connection with their regulatory or investigational authority. Such requests can include subpoenas or demand letters for documents to assist the government in audits or investigations. The Company reviews such requests and notices and takes appropriate action. Additionally, the Company is subject to federal and state requirements for protection of the environment, including those for disposal of hazardous waste and remediation of contaminated sites. As a result, the Company is required to participate in certain government investigations regarding environmental remediation actions.

In addition to the items addressed above, from time to time, the Company is subject to, and is presently involved in, litigation, legal proceedings, or other claims arising in the ordinary course of business. While the final outcome of these matters cannot be predicted with certainty, considering, among other things, the meritorious legal defenses available, the Company believes that, on a basis of information presently available, none of these items, when finally resolved, will have a material adverse effect on the Company’s long-term financial position or liquidity.

Customer and Vendor Claims

The Company receives, and is currently subject to, customer and vendor claims arising in the ordinary course of business, including, but not limited to, those related to product quality and late delivery. The Company accrues for matters when losses are deemed probable and reasonably estimable. In evaluating matters for accrual and disclosure purposes, the Company takes into consideration multiple factors including without limitation its historical experience with matters of a similar nature, the specific facts and circumstances asserted, the likelihood of an unfavorable outcome, and the severity of any potential loss. Any accruals deemed necessary are reevaluated at least quarterly and updated as matters progress over time.

The Company has evaluated and refined management’s original estimate of costs related to rework on the B787 aircraft, including a preliminary assessment related to rework on the forward section of the fuselage, for which the Company identified an additional fit and finish issue in the prior year. The Company continues to coordinate with Boeing to complete the necessary rework.

As described in Note 27 Subsequent Events, on October 12, 2023, the Company entered into a Memorandum of Agreement (the “MOA”) with Boeing. Among other things, the MOA includes a broad release of liability and claims through October 12, 2023, by both parties relating to Boeing's Commercial Airplanes division and its airplane programs under the General Terms Agreement for the B787 program and the General Terms Agreement for the B737, B747, B767, and B777 programs.

Contingencies

As described in Note 27 Subsequent Events, on October 12, 2023, the Company entered into the MOA with Boeing. Among other things, the MOA establishes certain recurring shipset price increases for the B787, and as a result the Company will reverse certain liabilities, including a certain amount of forward losses and material right obligation related to the B787 program in the fourth quarter of 2023.

In the third quarter of 2023, the Company updated its estimated cost to satisfy all customer firm orders on the A350 and A220 production programs. Based on forecasted backlog and rates of production, each of these programs anticipates production will extend beyond the period of time for which the Company has recorded forward losses. The Company has recorded forward losses for forecasted production on the A220 and A350 programs through the end of 2025. The Company is in active negotiations with its A220 and A350 customer, regarding, among other things, elements of price. Management has evaluated the probability that the unexercised options to complete the performance obligations for periods beyond the period of time for which it has recorded forward losses is not currently probable. While the Company does not currently believe incremental losses are evident on these programs, if negotiations with its customer do not achieve a result which eliminates or reduces the potential for incremental losses, or other strategic alternatives are abandoned, the Company believes it is reasonably possible it would record cumulative incremental losses across these programs between $0.0 and $255.0 million.

On April 12, 2023, the Company issued a notice of escapement to Boeing related to the quality issue on the B737 Vertical Fin Attach Fittings. The remediation of the quality issue requires the Company to rework B737 units within its production system and reimburse Boeing for repairs on previously delivered units in their factory and warranty costs related to units in service. As of June 29, 2023, the Company had completed the required rework on available units located at its factory in Wichita, KS. The impact to production costs is reflected within the reported total gross margins and did not materially change from the preliminary cost estimate of approximately $31.0 estimated as of March 31, 2023. Based upon informal communications to date with our customer, we believe Boeing has completed the required rework on approximately half of the affected units within its factory. The Company has not received a claim from Boeing for rework completed to date. However, the Company has made an estimate of the cost to Boeing for the units repaired to date of $23.0 for the period ended June 29, 2023. This amount is recorded as contra revenue. As described in Note 27 Subsequent Events, on October 12, 2023, the Company entered into the MOA with Boeing. Among other things, the MOA includes a broad release of liability and claims through October 12, 2023, by both parties relating to Boeing's Commercial Airplanes division and its airplane programs under the General Terms Agreement for the B787 program and the General Terms Agreement for the B737, B747, B767, and B777 programs. As a result, the Company will reverse the $23.0 contra revenue adjustment recorded in the three months ended June 29, 2023 during the three months ending December 31, 2023.

Guarantees

Contingent liabilities in the form of letters of guarantee have been provided by the Company. Outstanding guarantees were $22.8 and $13.9 at September 28, 2023 and December 31, 2022, respectively.

Restricted Cash - Collateral Requirements

The Company was required to maintain $22.2 and $19.6 of restricted cash as of September 28, 2023 and December 31, 2022, respectively, related to certain collateral requirements for obligations under its workers’ compensation programs. Restricted cash is included in Other assets in the Company's Condensed Consolidated Balance Sheets.

Indemnification

The Company has entered into customary indemnification agreements with its directors, and its bylaws and certain executive employment agreements include indemnification and advancement provisions. Pursuant to the terms of the bylaws and, with respect to Jose Garcia, his employment agreement, the Company is providing Messrs. Garcia and Gilson and all other individual defendants with defense costs and provisional indemnity with respect to the Consolidated Class Action and Derivative Actions, as well as for Mr. Gentile with regard to the Securities Class Action, as appropriate. Under the bylaws and any applicable agreements, the Company agrees to indemnify each of these individuals against claims arising out of events or occurrences related to that individual’s service as the Company’s agent or the agent of any of its subsidiaries to the fullest extent legally permitted.

The Company has agreed to indemnify parties for specified liabilities incurred, or that may be incurred, in connection with transactions they have entered into with the Company. The Company is unable to assess the potential number of future claims that may be asserted under these indemnities, nor the amounts thereof (if any). As a result, the Company cannot estimate the maximum potential amount of future payments under these indemnities and therefore, no liability has been recorded.

Service and Product Warranties and Extraordinary Rework

Provisions for estimated expenses related to service and product warranties and certain extraordinary rework are evaluated on a quarterly basis. These costs are accrued and are recorded to unallocated cost of goods sold. These estimates are established using historical information on the nature, frequency, and average cost of warranty claims, including the experience of industry peers. In the case of new development products or new customers, the Company considers other factors including the experience of other entities in the same business and management judgment, among others. Service warranty and extraordinary work is reported in current liabilities and other liabilities on the Company's Condensed Consolidated Balance Sheets.

The warranty balance presented in the table below includes unresolved warranty claims that are in dispute in regard to their value as well as their contractual liability. The Company estimated the total costs related to some of these claims; however, there is significant uncertainty surrounding the disposition of these disputed claims and as such, the ultimate determination of the provision’s adequacy requires significant management judgment. The amount of the specific provisions recorded against disputed warranty claims was $2.3 as of September 28, 2023 and December 31, 2022. These specific provisions represent the Company’s best estimate of probable warranty claims. Should the Company incur higher than expected warranty costs and/or discover new or additional information related to these warranty provisions, the Company may incur additional charges that exceed these recorded provisions. The Company utilized available information to make appropriate assessments, however the Company recognizes that data on actual claims experience is of limited duration and therefore, claims projections are subject to significant judgment. The amount of the reasonably possible disputed warranty claims in excess of the specific warranty provision was $3.4 as of September 28, 2023 and December 31, 2022.

The following is a roll forward of the service warranty and extraordinary rework balance at September 28, 2023:

Balance, December 31, 2022	$	74.9
Charges (release) to costs and expenses	0.1
Payouts	(2.2)
Exchange rate	(0.2)
Balance, September 28, 2023	$	72.6

Segment Reporting [Abstract]

Segment Information

Segment Information

The Company operates in three principal segments: Commercial, Defense & Space and Aftermarket. Approximately 81% and 82% of the Company's net revenues for the three and nine months ended September 28, 2023 came from the Company's two largest customers, Boeing and Airbus. Boeing represents a substantial portion of the Company's revenues across segments. Airbus represents a substantial portion of revenues in the Commercial segment. The Company's primary profitability measure to review a segment’s operating performance is segment operating income before corporate selling, general and administrative expenses and research and development.

Corporate selling, general and administrative expenses include centralized functions such as accounting, treasury and human resources that are not specifically related to the Company's operating segments and are not allocated in measuring the operating segments’ profitability and performance and net profit margins. Research and development includes research and development efforts that benefit the Company as a whole and are not unique to a specific segment. These items are not specifically related to the Company’s operating segments and are not utilized in measuring the operating segments’ profitability and performance.

The Company’s Commercial segment includes design and manufacturing of forward, mid, and rear fuselage sections and systems, struts/pylons, nacelles (including thrust reversers) and related engine structural components, wings, and wing components (including flight control surfaces), as well as other miscellaneous structural parts for large commercial aircraft and/or business/regional jets. Sales from this segment are primarily to the aircraft OEMs or engine OEMs of large commercial aircraft and/or business/regional jet programs. Approximately 69% and 65% of Commercial segment net revenues came from the Company's contracts with Boeing for the nine months ended September 28, 2023, and September 29, 2022, respectively. Approximately 24% and 27% of Commercial segment net revenues came from the Company's contracts with Airbus for the nine months ended September 28, 2023, and September 29, 2022, respectively. The Commercial segment manufactures products at the Company's facilities in Wichita, Kansas; Tulsa, Oklahoma; Kinston, North Carolina; Prestwick, Scotland; Casablanca, Morocco; Belfast, Northern Ireland; and Subang, Malaysia.  The Commercial segment also includes an assembly plant for the A350 XWB aircraft in Saint-Nazaire, France.

The Company's Defense & Space segment includes design and manufacturing of fuselage, strut, nacelle, and wing aerostructures (primarily) for U.S. Government defense programs, including Boeing P-8, C40, and KC-46 Tanker, which are commercial aircraft that are modified for military use. The segment also includes fabrication, bonding, assembly, testing tooling, processing, engineering analysis, and training on fixed wing aircraft aerostructures, missiles and hypersonics work, including solid rocket motor throats and nozzles and re-entry vehicle thermal protections systems, forward cockpit and cabin, and fuselage work on rotorcraft aerostructures. Sales from this segment are primarily to the prime contractors on various U.S. Government defense program contracts for which the Company is a sub-contractor. A significant portion of the Company's Defense & Space segment revenues are represented by defense business that is classified by the U.S. Government and cannot be specifically described. A significant portion of Defense & Space segment net revenues came from the Company's contracts with two individual customers for the nine months ended September 28, 2023, and September 29, 2022. The Defense & Space segment manufactures products at the Company's facilities in Wichita, KS; Tulsa, OK; Biddeford, ME; Woonsocket, RI; Belfast, Northern Ireland; and Prestwick, Scotland.

The Company's Aftermarket segment includes design, manufacturing, and marketing of spare parts and maintenance, repair, and overhaul (“MRO”) services, repairs for flight control surfaces and nacelles, radome repairs, rotable assets, engineering services, advanced composite repair, and other repair and overhaul services. Approximately 47% and 47% of Aftermarket segment net revenues came from the Company's contracts with a single customer for the nine months ended September 28, 2023, and September 29, 2022, respectively. The Aftermarket segment manufactures products at the Company's facilities in Wichita, KS; Tulsa, OK; Kinston, North Carolina; Dallas, TX; Prestwick, Scotland; Casablanca, Morocco; and Belfast, Northern Ireland.

  The Company’s segments are consistent with the organization and responsibilities of management reporting to the chief operating decision-maker for the purpose of assessing performance. The Company’s definition of segment operating income differs from Operating income as presented in its primary financial statements and a reconciliation of the segment and consolidated results is provided in the table set forth below.

 While some working capital accounts are maintained on a segment basis, much of the Company’s assets are not managed or maintained on a segment basis. Property, plant, and equipment, including tooling, is used in the design and production of

products for each of the segments and, therefore, is not allocated to any individual segment. In addition, cash, prepaid expenses, other assets, and deferred taxes are managed and maintained on a consolidated basis and generally do not pertain to any particular segment. Raw materials and certain component parts are used in aerostructure production across all segments. Work-in-process inventory is identifiable by segment but is managed and evaluated at the program level. As there is no segmentation of the Company’s productive assets, depreciation expense (included in fixed manufacturing costs and selling, general and administrative expenses) and capital expenditures, no allocation of these amounts has been made solely for purposes of segment disclosure requirements.

The following table shows segment revenues and operating income (loss) for the nine months ended September 28, 2023 and September 29, 2022:

	Three Months Ended				Nine Months Ended

Restructuring Costs

The Company's results of operations for the nine months ended September 28, 2023 include restructuring costs related to the Voluntary Separation Program (“VSP”) that was offered to reduce structural costs by reducing indirect headcount. Participants in the VSP received a lump sum severance payment based on their years of Company service.

Restructuring costs are presented separately as a component of operating loss on the Condensed Consolidated Statements of Operations. The total restructuring costs for the three and nine months ended September 28, 2023 were $0.0 and $7.2,

respectively, of which, $6.3 was included in segment operating margins for the Commercial Segment and $0.9 was included in segment operating margins for the Defense & Space Segment.

The Company's results of operations for the nine months ended September 29, 2022 includes restructuring costs related to actions the Company has taken to align costs to updated production levels that have been directed by the Company's customers (restructuring activity). Largely beginning in the first quarter of 2020, the Company's customers, including Boeing and Airbus, significantly reduced their overall production rates as a result of the COVID-19 pandemic and, in the case of Boeing, the B737 MAX grounding. The restructuring activity materially affected the scope of operations and manner in which business is conducted by the Company compared to periods prior to the restructuring activities.

The total restructuring costs for the three and nine months ended September 29, 2022 were $0.0 and $0.2, respectively, and are included in segment operating margins for the Commercial Segment.

Payables and Accruals [Abstract]

Supplier Finance Program

25. Supplier Financing

The Company has provided certain suppliers with access to a supply chain financing program through a facility with a third-party financing institution. The Company's suppliers' ability to access the program is primarily dependent upon the strength of the Company's financial condition and certain qualifying criteria. This program was primarily entered into as a result of the Company seeking payment term extensions with production suppliers, and the program allows these suppliers to monetize their receivables prior to the contractual payment date, subject to payment of a discount. The capacity of the program is limited to $97.0 at any point in time. If a supplier's request exceeds the program limit, then it will be honored when capacity is available. Under the supply chain financing program, the Company agrees to pay the third-party financing institution the stated amount of confirmed invoices from its designated suppliers on the original maturity dates of the invoices, and suppliers have the ability to be paid from the third-party financing institution on an accelerated basis. The Company’s suppliers’ election to sell one or more of the Company’s confirmed obligations under the supply chain financing program is optional. The Company's responsibility is limited to making payment on the terms originally negotiated with its suppliers for up to 120 days, regardless of whether the suppliers elect to sell their receivables to the third-party financing institution. The Company or the third-party financing institution may terminate the agreement upon at least 45 days’ notice.

The balance of confirmed obligations outstanding to suppliers who elect to participate in the supply chain financing program is included in the Company’s accounts payable balance on the Company’s Condensed Consolidated Balance Sheets. As of September 28, 2023, the balance of confirmed obligations outstanding was $112.7, an increase of $10.7 over the balance as of December 31, 2022 of $102.0. In the comparable prior year period, confirmed obligations outstanding were $103.5 as of September 29, 2022, an increase of $44.6 over the balance as of December 31, 2021. The changes in each period primarily reflect purchases from suppliers related to production levels during the respective periods.

On October 12, 2023, Spirit and The Boeing Company executed the MOA to support production stability. The MOA establishes recurring shipset price increases for the B787 program effective for LN 1164 through LN 1605, recurring shipset price adjustments on the B737 program effective from the first delivery in 2026 through June 2033, releases of liabilities and claims through the effective date of the MOA by both parties relating to Boeing’s Commercial Airplanes division and its airplane programs under the General Terms Agreement for the B787 program and the General Terms Agreement for the B737, B747, B767 and B777 programs unless explicitly excluded within the MOA, Boeing provided funding for tooling and capital through 2025 for certain planned and potential B737 and B787 rate increases, amendment of repayment dates for outstanding customer financing, and changes to terms governing assignments. Regarding the tooling and capital funding, approximately $100.7 was received during the fourth quarter of 2023.

As a result of the MOA, which was executed in the fourth quarter, we expect to reverse liabilities, including previously recorded forward losses and material right obligation on the B787 program of between approximately $350.0 to $370.0 in the fourth quarter of 2023 which represents a preliminary estimate which could be subject to change based on certain performance during the fourth quarter. Regarding the $180.0 of advances received as customer financing in the quarter ended June 29, 2023, per the terms of the MOA, the repayment dates were amended. The amended repayment dates require repayment of $90.0 in December 2025 and equal payments of $45.0 in December 2026 and 2027. Additionally and separate from the range above, related to the release of claims, we will be reversing liabilities for certain claims received and other anticipated claims on our balance sheet in the fourth quarter of 2023 including the $23.0 of anticipated claims related to the Boeing 737 Vertical Fin Attach Fittings previously disclosed.

Leases [Abstract]

Lessee, Leases [Policy Text Block]

The Company determines if an arrangement is a lease at the inception of a signed agreement. Operating leases are included in right-of-use (“ROU”) assets (long-term), short-term operating lease liabilities, and long-term operating lease liabilities on the Company’s Condensed Consolidated Balance Sheets. Finance leases are included in Property, Plant and Equipment, current maturities of long-term debt, and long-term debt.

ROU assets represent the right of the Company to use an underlying asset for the length of the lease term, and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term.

To determine the present value of lease payments, the Company uses its estimated incremental borrowing rate or the implicit rate, if readily determinable. The estimated incremental borrowing rate is based on information available at the lease commencement date, including any recent debt issuances and publicly available data for instruments with similar characteristics. The ROU asset also includes any lease payments made and excludes lease incentives.

The Company's lease terms may include options to extend or terminate the lease and, when it is reasonably certain that an option will be exercised, those options are included in the net present value calculation. Leases with a term of 12 months or less, which are primarily related to automobiles and manufacturing equipment, are not recorded on the Condensed Consolidated Balance Sheets. The aggregate amount of lease cost for leases with a term of 12 months or less is not material.

The Company has lease agreements that include lease and non-lease components, which are generally accounted for separately. For certain leases (primarily related to IT equipment), the Company does account for the lease and non-lease components as a single lease component. A portfolio approach is applied to effectively account for the ROU assets and liabilities for those specific leases referenced above. The Company does not have any material leases containing variable lease payments or residual value guarantees. The Company also does not have any material subleases

Fair Value Measurements (Tables)

Fair Value Disclosures [Abstract]

Fair Value Measurements

The guidance discloses three levels of inputs that may be used to measure fair value:

Level 1 Quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 1 assets and liabilities include debt and equity securities and derivative contracts that are traded in an active exchange market.

Level 2                      Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 2 assets and liabilities include debt securities with quoted prices that are traded less frequently than exchange-traded instruments and derivative contracts whose value is determined using a pricing model with inputs that are observable in the market or can be derived principally from or corroborated by observable market data. Observable inputs, such as current and forward interest rates and foreign exchange rates, are used in determining the fair value of the interest rate swaps and foreign currency hedge contracts.

Level 3                 Unobservable inputs that are supported by little or no market activity and are significant to the fair value of assets and liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

(1)    In July 2022, the Company adopted and communicated to participants a plan to terminate the Company's Pension Value Plan A (“PVP A”). As further described in the Company's 2021 Form 10-K, the PVP A consists of pension plans which were frozen as of the date Holdings became a standalone company and commenced operations. During the three months ended September 29, 2022, the PVP A plan was amended, providing for an enhancement to benefits the Company is providing to certain U.S. employees in conjunction with the plan termination. The estimated liability impact of this plan amendment, $71.7, was recognized immediately as a non-cash, pre-tax non-operating charge for amortization of prior service costs.

(2) Includes a $64.6 settlement charge for the PVP A during the nine months ended September 28, 2023. Includes a $0.9 settlement charge for the PVP A during the three months ended September 29, 2022, and a ($1.4) settlement credit for PVP B related to final asset distribution in the nine months ended September 29, 2022.

The components of net periodic pension expense (income) and other benefit income, other than the service cost component, are included in Other income (expense), net in the Company's Condensed Consolidated Statements of Operations. See Note 21 Other Income (Expense), Net.

As disclosed in the Company's 2022 Form 10-K, effective October 1, 2021, the Company spun off a portion of the existing PVP A, to a new plan called PVP B (“PVP B”). As part of the PVP B plan termination process, a lump sum offering was provided during 2021 for PVP B participants and the final asset distribution was completed in the first quarter of 2022. At September 28, 2023, a pension reversion asset of $61.4 is recorded on the Restricted plan assets line item on the Company’s Condensed Consolidated Balance Sheets. Restricted plan assets are expected to be reduced over the next six years as they are

distributed to employees under a qualified compensation and benefit program. Restricted plan assets are valued at fair value with gain or loss on fair value adjustments recognized within other income. The underlying investments' fair value measurement levels under the FASB's authoritative guidance on fair value measurements are Level 2, see Note 13 Fair Value Measurements.

Separately, during the nine months ended September 28, 2023, the Company received an excess plan asset reversion of $179.5 of cash from PVP A. During the nine months ended September 29, 2022, the Company withdrew $34.0 of cash from PVP B, which represented an excess plan assets reversion. These transactions were accounted for as a negative contribution and are included on the Pension plans employer contributions line item on the Condensed Consolidated Statements of Cash Flows for the nine months ended September 28, 2023 and September 29, 2022. Excise tax of $35.9 and $6.8 related to the reversion of excess plan assets was separately recorded to the Other income (expense), net line item on the Company's Condensed Consolidated Statements of Operations for the nine months ended September 28, 2023 and September 29, 2022, respectively. See also Note 21 Other Income (Expense), Net.

As disclosed in the Company's 2022 Form 10-K, in July 2022, the Company adopted and communicated to participants a plan to terminate the PVP A. During the nine months ended September 28, 2023, the Company recognized non-cash, pre-tax non-operating accounting charges of $64.6 related to the plan termination, primarily reflecting the accounting for a group annuity purchase made in the first quarter of 2023, which resulted in a settlement charge related to the accelerated recognition of the actuarial losses for the PVP A plan that were previously included in the Accumulated other comprehensive loss line item in the Stockholders' Equity section of the Company's Condensed Consolidated Balance Sheets.

In connection with the special accounting related to the termination of the PVP A plan, discussed above, a subsequent interim measurement of the Company's U.S. pension and other postretirement plan assets and obligations was completed during the three months ended September 29, 2022. The interim measurement, including the estimated impact of the plan termination liability and enhanced benefits liability noted above, prior to the current period settlement loss and amortization of prior service cost impacts included in Net Periodic Pension Expense above, was recorded to the Accumulated other comprehensive loss line item in the Stockholders' Equity section of the Company's Condensed Consolidated Balance Sheet for the period ended September 29, 2022.

Included in the outstanding Common Stock were 0.1 million and 0.4 million of issued but unvested shares at September 28, 2023 and September 29, 2022, respectively, which are excluded from the basic Earnings Per Share (“EPS”) calculation.

Shares of Common Stock of 0.6 million and 0.7 million, respectively, were excluded from diluted EPS as a result of incurring a net loss for the three and nine months ended September 28, 2023, as the effect would have been antidilutive. Additionally, diluted EPS for the three and nine months ended September 28, 2023 excludes 0.2 million shares that may be dilutive shares of Common Stock in the future but were not included in the computation of diluted EPS because the effect was either antidilutive or the performance condition was not met.

Shares of Common Stock of 0.5 million and 0.6 million, respectively, were excluded from diluted EPS as a result of incurring a net loss for the three and nine months ended September 29, 2022, as the effect would have been antidilutive. Additionally, diluted EPS for the three and nine months ended September 29, 2022 excludes 0.3 million shares that may be dilutive shares of Common Stock in the future but were not included in the computation of diluted EPS because the effect was either antidilutive or the performance condition was not met.

Derivative, Credit Risk Related Contingent Features, Existence and Nature			Generally, the Company has agreements with its counterparties that contain a provision whereby if the Company defaults on its existing credit facilities and payment of the loans extended under such facilities is accelerated, the Company could be declared in default under its agreements, which may result in the early termination of the outstanding derivatives governed by such agreements and the payment of an early termination amount.
General Cash Flow Hedge Information [Abstract]
Objectives for Using Cash Flow Hedging Instruments			The Company has entered into currency forward contracts, each designated as a cash flow hedge upon the date of execution, for the purpose of reducing the variability of cash flows and hedging against the foreign currency exposure for forecasted payroll, pension and vendor disbursements that are expected to be made in the British Pound Sterling. The hedging program implemented is intended to reduce foreign currency exposure, and the associated forward currency contracts hedge forecasted transactions through June 2024.
Description of Foreign Currency Derivative Instruments Not Designated as Hedging Instruments Activities			During the nine months ended September 29, 2022, the Company entered into foreign currency forward contracts in the amount of $291.5 to minimize the risk of currency exchange rate movements on the Company's planned settlement of the repayable investment agreement between the Company and the U.K.'s Department for Business, Energy and Industrial Strategy. During the nine-month period ended September 29, 2022, these foreign currency forward contracts were settled, and new contracts were entered into in the amount of $293.7, which were also settled during the period. The Company did not designate these forward contracts as hedges or apply hedge accounting to the forward contracts.
