TRANSDIGM GROUP INCORPORATED

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

THIRTEEN WEEK PERIODS ENDED DECEMBER 30, 2023 AND DECEMBER 31, 2022

(UNAUDITED)

1.    BASIS OF PRESENTATION

As used in this Quarterly Report on Form 10-Q, unless the context otherwise requires, the terms “Company”, “TD Group”, “TransDigm”, “we” or “us” refer to TransDigm Group Incorporated and its subsidiaries.

Principles of Consolidation

The financial information included herein is unaudited; however, the information reflects all adjustments (consisting of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s condensed consolidated financial statements for the interim periods presented. These financial statements and notes should be read in conjunction with the financial statements and related notes for the fiscal year ended September 30, 2023 included in TD Group’s Annual Report on Form 10-K filed on November 9, 2023. As disclosed therein, the Company’s annual consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”). The September 30, 2023 condensed consolidated balance sheet was derived from TD Group’s audited financial statements. The results of operations for the thirteen week period ended December 30, 2023 are not necessarily indicative of the results to be expected for the full year.

Reclassifications

Certain reclassifications have been made to the prior year amounts to conform to the current year presentation, none of which are material.

New Accounting Pronouncements Issued

In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” to amend certain disclosure and presentation requirements for a variety of topics within the ASC. These amendments align the requirements in the ASC to the removal of certain disclosure requirements set out in Regulation S-X and Regulation S-K, announced by the SEC. The effective date for each amended topic in the ASC is either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirements by that date. Early adoption is prohibited. The Company does not expect that the application of this standard will have an impact on our condensed consolidated financial statements and disclosures.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” ASU 2023-07 expands disclosures about a public business entity's reportable segments and provides for more detailed information about a reportable segment's expenses. Additionally, ASU 2023-07 requires all segment profit or loss and assets disclosures to be provided on an annual and interim basis. This standard is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning one year later. Early adoption is permitted. The Company is currently evaluating this standard to determine its impact on our disclosures.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires a public business entity to disclose specific categories in its annual effective tax rate reconciliation and disaggregated information about significant reconciling items by jurisdiction and by nature. The ASU also requires entities to disclose their income tax payments (net of refunds) to international, federal, and state and local jurisdictions. The standard makes several other changes to income tax disclosure requirements. This standard is effective for annual periods beginning after December 15, 2024, and requires prospective application with the option to apply it retrospectively. Early adoption is permitted. The Company is currently evaluating this standard to determine its impact on our disclosures.

2.    ACQUISITIONS

CPI Electron Device Business – On November 9, 2023, the Company entered into a definitive agreement to acquire the Electron Device Business of Communications & Power Industries (“CPI”), a portfolio company of TJC, L.P., for approximately $1,385 million in cash. CPI’s Electron Device Business is a leading global manufacturer of electronic components and subsystems primarily serving the aerospace and defense market. Its products are highly engineered, proprietary components with significant aftermarket content and a strong presence across major aerospace and defense platforms. The acquisition is expected to close in fiscal 2024, subject to regulatory approvals in the United States (“U.S.”) and United Kingdom and customary closing conditions. The acquisition is expected to be financed through existing cash on hand, inclusive of a portion of the cash proceeds from the new long-term debt issued in the first quarter of fiscal 2024. Refer to Note 7, “Debt,” for further disclosure of the aforementioned debt issuances.

Calspan Corporation – On March 14, 2023, the Company entered into a definitive agreement to acquire all the outstanding stock of Calspan Corporation (“Calspan”) for a total purchase price of $730 million, which includes a $1 million working capital settlement paid in the first quarter of fiscal 2024. The acquisition was completed on May 8, 2023 and financed through existing cash on hand. Calspan operates from seven primary facilities within the U.S. and is a leading independent provider of proprietary highly engineered testing and technology development services and systems primarily for the aerospace and defense industry. Calspan’s state of the art transonic wind tunnel is used across a range of important aftermarket-focused development activities for both the commercial and defense aerospace end markets. The services and systems are primarily proprietary with significant aftermarket content. Calspan's operating results are included within TransDigm's Airframe segment as of the May 8, 2023 acquisition date.

As of December 30, 2023, the measurement period (not to exceed one year) is open; therefore, the assets acquired and liabilities assumed related to the Calspan acquisition are subject to adjustment until the end of the respective measurement period.

The Company is in the process of finalizing a third-party valuation of property, plant and equipment and certain intangible assets of Calspan. The allocation of the purchase price is preliminary and will likely change in future periods, perhaps materially, as fair value estimates of the assets acquired and liabilities assumed are finalized, including those related to deferred taxes and income taxes. We utilized both the cost and market approaches to value property, plant and equipment, which consider external transactions and other comparable transactions, estimated replacement and reproduction costs, and estimated useful lives and consideration for physical, functional and economic obsolescence. The fair values of acquired intangibles are determined based on an income approach, using estimates and assumptions that are deemed reasonable by the Company. Significant assumptions include the discount rates and certain assumptions that form the basis of the forecasted results of the acquired business including revenue, earnings before interest, taxes, depreciation and amortization (“EBITDA”), growth rates, royalty rates and technology obsolescence rates. These assumptions are forward looking and could differ from future economic and market conditions.

Pro forma net sales and results of operations for the Calspan acquisition had it occurred at the beginning of the thirteen week period ended December 31, 2022 are not material and, accordingly, are not provided.

7

The allocation of the estimated fair value of assets acquired and liabilities assumed in the Calspan acquisition as of the May 8, 2023 acquisition date, as well as measurement period adjustments recorded within the permissible one year measurement period, are summarized in the table below (in millions):

	Preliminary		Measurement Period		Adjusted Preliminary
	Allocation		Adjustments (2)		Allocation
Assets acquired (excluding cash):
Trade accounts receivable	$	39	$	—	$	39
Inventories	2		—		2
Prepaid expenses and other	40		—		40
Property, plant and equipment	105		278		383
Goodwill	367		(122)		245		(1)
Other intangible assets	243		(151)		92		(1)
Other non-current assets	7		—		7
Total assets acquired (excluding cash)	803		5		808
Liabilities assumed:
Accounts payable	10		(1)		9
Accrued and other current liabilities	50		—		50
Deferred income taxes	8		5		13
Other non-current liabilities	6		—		6
Total liabilities assumed	74		4		78
Net assets acquired	$	729	$	1	$	730

(1)Of the approximately $245 million of goodwill recognized for the acquisition, the Company expects that approximately $218 million will be deductible for tax purposes. Of the approximately $92 million of other intangible assets recognized for the acquisition, the Company expects that approximately $86 million will be deductible for tax purposes. The goodwill and intangible assets are expected to be deductible over 15 years.

(2)Measurement period adjustments primarily related to the adjustments in the fair values of the acquired property, plant and equipment and other intangible assets from the third-party valuation. A substantial portion of the measurement period adjustments to property, plant and equipment relates to the fair value of the transonic wind tunnel. The offset to the measurement period adjustments was to goodwill.

Extant Aerospace Acquisitions – For the thirteen week period ended December 30, 2023, the Company's Extant Aerospace subsidiary, which is included within TransDigm’s Power & Control segment, completed an acquisition of substantially all of the assets and technical data rights of a certain product line, which met the definition of a business, for a total purchase price of $13 million. The allocation of the purchase price remains preliminary and will likely change, though not materially, in future periods up to the expiration of the respective one year measurement period as fair value estimates of the assets acquired and liabilities assumed are finalized. The Company expects that all of the approximately $6 million of goodwill and $3 million of other intangible assets recognized for the acquisition will be deductible for tax purposes over 15 years.

For the fiscal year ended September 30, 2023, the Company's Extant Aerospace subsidiary, completed a series of acquisitions of substantially all of the assets and technical data rights of certain product lines, each meeting the definition of a business, for a total purchase price of $24 million. The allocation of the purchase price remains preliminary and will likely change, though not materially, in future periods up to the expiration of the respective one year measurement period as fair value estimates of the assets acquired and liabilities assumed are finalized. The Company expects that all of the approximately $12 million of goodwill and $6 million of other intangible assets recognized for the acquisitions will be deductible for tax purposes over 15 years.

Pro forma net sales and results of operations for the Extant Aerospace product line acquisitions, had they occurred at the beginning of the thirteen week periods ended December 30, 2023 or December 31, 2022 are not material and, accordingly, are not provided.

8

The acquisitions completed by the Company strengthen and expand the Company’s position to design, produce and supply highly engineered proprietary aerospace components in niche markets with significant aftermarket content and provide opportunities to create value through the application of our three core value-driven operating strategy (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers). The purchase prices paid reflect the current EBITDA and cash flows, as well as the future EBITDA and cash flows expected to be generated by the businesses, which are driven in most cases by the recurring aftermarket consumption over the life of a particular aircraft, estimated to be approximately 25 to 30 years.

3.    REVENUE RECOGNITION

TransDigm's sales are concentrated in the aerospace and defense industry. The Company’s customers include: distributors of aerospace components, commercial airlines, large commercial transport and regional and business aircraft original equipment manufacturers (“OEMs”), various armed forces of the U.S. and friendly foreign governments, defense OEMs, system suppliers, and various other industrial customers.

The Company recognizes revenue from contracts with customers using the five step model prescribed in ASC 606. A substantial portion of the Company's revenue is recorded at a point in time basis. Revenue is recognized from the sale of products or services when obligations under the terms of the contract are satisfied and control of promised goods or services have transferred to the customer. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services. Revenue is measured at the amount of consideration the Company expects to be paid in exchange for goods or services.

In certain contracts, control transfers to the customer over time, primarily in contracts where the customer is required to pay for the cost of both the finished and unfinished goods at the time of cancellation plus a reasonable profit relative to the work performed for products that were customized for the customer. Therefore, we recognize revenue over time for those agreements that have a right to margin and where the products being produced have no alternative use. 

Based on our production cycle, it is generally expected that goods related to the revenue will be shipped and billed within twelve months. For revenue recognized over time, we estimate the amount of revenue attributable to a contract earned at a given point during the production cycle based on certain costs, such as materials and labor incurred to date, plus the expected profit, which is a cost-to-cost input method.

We consider the contractual consideration payable by the customer and assess variable consideration that may affect the total transaction price. Variable consideration is included in the estimated transaction price when there is a basis to reasonably estimate the amount, including whether the estimate should be constrained in order to avoid a significant reversal of revenue in a future period. These estimates are based on historical experience, anticipated performance under the terms of the contract and our best judgment at the time.

When contracts are modified to account for changes in contract specifications and requirements, the Company considers whether the modification either creates new or changes the existing enforceable rights and obligations. Contract modifications that are for goods or services that are not distinct from the existing contract, due to the significant integration with the original good or service provided, are accounted for as if they were part of that existing contract. The effect of a contract modification to an existing contract on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct and at relative stand-alone selling price, they are accounted for as a new contract and performance obligation, which are recognized prospectively.

The Company’s payment terms vary by the type and location of the customer and the products or services offered. The Company does not offer any payment terms that would meet the requirements for consideration as a significant financing component.

Shipping and handling fees and costs incurred in connection with products sold are recorded in cost of sales in the consolidated statements of income, and are not considered a performance obligation to our customers.

The Company pays sales commissions that relate to contracts for products or services that are satisfied at a point in time or over a period of one year or less and are expensed as incurred. These costs are reported as a component of selling and administrative expenses in the condensed consolidated statements of income.

9

Contract Assets and Liabilities – Contract assets reflect revenue recognized and performance obligations satisfied in advance of customer billing or reimbursable costs related to a specific contract. Contract liabilities (Deferred revenue) relate to payments received in advance of the satisfaction of performance under the contract. We receive payments from customers based on the terms established in our contracts. The following table summarizes our contract assets and liabilities balances (in millions):

	December 30, 2023		September 30, 2023
Contract assets, current (1)	$	196	$	191
Contract assets, non-current (2)	—		1
Total contract assets	196		192
Contract liabilities, current (3)	92		79
Contract liabilities, non-current (4)	7		8
Total contract liabilities	99		87

(2)Included in other non-current assets on the condensed consolidated balance sheets.

(3)Included in accrued and other current liabilities on the condensed consolidated balance sheets.

(4)Included in other non-current liabilities on the condensed consolidated balance sheets.

The increase in the Company's total contract assets at December 30, 2023 compared to September 30, 2023 is primarily due to the timing and status of work in process and/or milestones of certain contracts. The increase in the Company's total contract liabilities at December 30, 2023 compared to September 30, 2023 is primarily due to the receipt of advance payments. For the thirteen week period ended December 30, 2023, the revenue recognized that was previously included in contract liabilities was approximately $9 million.

Refer to Note 11, “Segments,” for disclosures related to the disaggregation of revenue.

Allowance for Credit Losses – The Company's allowance for credit losses is the allowance for uncollectible accounts. The allowance for uncollectible accounts reduces the trade accounts receivable balance to the estimated net realizable value equal to the amount that is expected to be collected.

The Company’s method for developing its allowance for credit losses is based on historical write-off experience, the aging of receivables, an assessment of the creditworthiness of customers, economic conditions and other external market information and supportable forward-looking information. The allowance also incorporates a provision for the estimated impact of disputes with customers. All provisions for allowances for uncollectible accounts are included in selling and administrative expenses. The determination of the amount of the allowance for uncollectible accounts is subject to judgment and estimation by management. If circumstances change or economic conditions deteriorate or improve, the allowance for uncollectible accounts could increase or decrease.

As of December 30, 2023 and September 30, 2023, the allowance for uncollectible accounts was $33 million and $31 million, respectively. The allowance for uncollectible accounts is assessed individually at each operating unit by the operating unit’s management team.

Amendment No. 13 and Incremental Term Loan Assumption Agreement – On November 28, 2023, the Company entered into Amendment No. 13 and Incremental Term Loan Assumption Agreement (herein, “Amendment No. 13”) to the Second Amended and Restated Credit Agreement dated as of June 4, 2014 (the “Credit Agreement”). Under the terms of Amendment No. 13, the Company, among other things, issued $1,000 million in Tranche J term loans maturing February 28, 2031. The Tranche J term loans bear interest at a rate of adjusted Term Secured Overnight Financing Rate (“Term SOFR”) plus an applicable margin of 3.25%. The Tranche J term loans were issued at a discount of 0.25%, or approximately $3 million. The Tranche J term loans were fully drawn on November 28, 2023 and the other terms and conditions that apply to the Tranche J term loans are substantially the same as the terms and conditions that apply to the term loans immediately prior to Amendment No. 13. Principal payments commence on March 31, 2024, in which $3 million will be paid on a quarterly basis up to the maturity date.

The Company capitalized $10 million in debt issuance costs associated with the Tranche J term loans during the thirteen week period ended December 30, 2023.

Issuance of $1,000 million Senior Secured Notes due 2031 – On November 28, 2023, the Company entered into a purchase agreement in connection with a private offering of $1,000 million in aggregate principal amount of 7.125% senior secured notes due 2031 (the “2031 Secured Notes”) at an issue price of 99.25% of the principal amount, which represents an approximately $8 million discount. The 2031 Secured Notes were issued pursuant to an indenture, dated as of November 28, 2023, amongst TransDigm Inc., as issuer, TransDigm Group and the other subsidiaries of TransDigm Inc. named therein, as guarantors. The 2031 Secured Notes are guaranteed, on a senior secured basis, by TransDigm Group and each of TransDigm Inc.’s direct and indirect restricted subsidiaries that is a borrower or guarantor under TransDigm’s senior secured credit facilities or that issues or guarantees any capital markets indebtedness of TransDigm or any of the guarantors in an aggregate principal amount of at least $200 million. The 2031 Secured Notes and guarantees rank equally in right of payment with all of TransDigm’s and the guarantors’ existing and future senior indebtedness, senior in right of payment to any of TransDigm’s and the guarantors’ existing and future indebtedness that is, by its terms, expressly subordinated in right of payment to the 2031 Secured Notes and guarantees, and structurally subordinated to all of the liabilities of TransDigm’s non-guarantor subsidiaries.

The 2031 Secured Notes bear interest at a rate of 7.125% per annum, which accrues from November 28, 2023 and is payable in arrears on June 1 and December 1 of each year, commencing on June 1, 2024. The 2031 Secured Notes mature on December 1, 2031, unless earlier redeemed or repurchased, and are subject to the terms and conditions set forth in the indenture.

The Company capitalized $10 million in debt issuance costs associated with the 2031 Secured Notes during the thirteen week period ended December 30, 2023.

Trade Receivable Securitization Facility – The Company’s trade receivable securitization facility (the “Securitization Facility”) effectively increases the Company’s borrowing capacity depending on the amount of the domestic operations’ trade accounts receivable. The Securitization Facility includes the right for the Company to exercise annual one year extensions as long as there have been no termination events as defined by the agreement. The Company uses the proceeds from the Securitization Facility as an alternative to other forms of debt, effectively reducing borrowing costs.

On July 25, 2023, the Company amended the Securitization Facility to, among other things, increase the borrowing capacity from $350 million to $450 million and extend the maturity date to July 25, 2024. During the first quarter of fiscal 2024, the Company drew the remaining $100 million available under the Securitization Facility. As of December 30, 2023, the Company has borrowed $450 million under the Securitization Facility, which is fully drawn, and bears interest at a rate of 1.6% plus Term SOFR. At December 30, 2023, the applicable interest rate was 6.99%. The Securitization Facility is collateralized by substantially all of the Company’s domestic operations’ trade accounts receivable.

Government Refundable Advances – Government refundable advances consist of payments received from the Canadian government to assist in research and development related to commercial aviation. The requirement to repay this advance is based on year-over-year commercial aviation revenue growth for certain product lines at CMC Electronics, which is a wholly-owned subsidiary of TransDigm. As of December 30, 2023 and September 30, 2023, the outstanding balance of these advances was $21 million.

Obligations under Finance Leases – The Company leases certain buildings and equipment under finance leases. The present value of the minimum finance lease payments, net of the current portion, represents a balance of $254 million and $193 million at December 30, 2023 and September 30, 2023, respectively. The increase in the current fiscal year is attributable to certain new leases of facilities and amendments to previous agreements qualifying as lease modifications resulting in a change in classification from an operating lease to a finance lease. Refer to Note 13, “Leases,” for further disclosure of the Company's lease obligations.

8.    INCOME TAXES

At the end of each reporting period, TD Group makes an estimate of its annual effective income tax rate. The estimate used in the year-to-date period may change in subsequent periods.

During the thirteen week periods ended December 30, 2023 and December 31, 2022, the effective income tax rate was 21.7% and 23.9%, respectively. The Company’s lower effective income tax rate for the thirteen week period ended December 30, 2023, was primarily due to a more significant discrete impact of excess tax benefits associated with share-based payments. The Company's effective income tax rate for the thirteen week period ended December 30, 2023 was slightly higher than the federal statutory tax rate of 21% primarily due to an increase in the valuation allowance applicable to the Company's net interest deduction limitation carryforward, offset by the discrete impact of excess tax benefits associated with share-based payments.

14

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state, local and foreign jurisdictions. The Company is no longer subject to U.S. federal examinations for years before fiscal 2018. The Company is currently under examination for its federal income taxes in Canada for fiscal years 2013 through 2019, in France for fiscal years 2020 through 2022, and in Germany for fiscal years 2014 through 2019. In addition, the Company is subject to state income tax examinations for fiscal years 2015 and later.

Unrecognized tax benefits at December 30, 2023 and September 30, 2023, the recognition of which would have an impact on the effective tax rate for each fiscal year, amounted to $17 million. The Company classifies all income tax-related interest and penalties as income tax expense, which were not significant for the thirteen week periods ended December 30, 2023 and December 31, 2022. As of December 30, 2023 and September 30, 2023, the Company accrued $6 million for the potential payment of interest and penalties. Within the next twelve months, it is reasonably possible that unrecognized tax benefits could be reduced by approximately $6 million resulting from the resolution or closure of tax examinations. Any increase in the amount of unrecognized tax benefits within the next twelve months is not expected to be material.

9.    FAIR VALUE MEASUREMENTS

The following table presents our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The following summarizes the carrying amounts and fair values of financial instruments (in millions):

		December 30, 2023				September 30, 2023
	Level	Carrying Amount		Fair Value		Carrying Amount		Fair Value

(3)Included in accrued and other current liabilities on the condensed consolidated balance sheets.

(4)Included in other non-current liabilities on the condensed consolidated balance sheets.

(5)The carrying amount of the debt instrument is presented net of debt issuance costs, premium and discount. Refer to Note 7, “Debt,” for gross carrying amounts.

The Company values its financial instruments using an industry standard market approach, in which prices and other relevant information are generated by market transactions involving identical or comparable assets or liabilities. No financial instruments were recognized or disclosed using unobservable inputs (i.e., Level 3).

The Company’s derivatives consist of interest rate swap, cap and collar agreements and foreign currency exchange contracts. The fair values of the interest rate swap, cap and collar agreements were derived by taking the net present value of the expected cash flows using observable market inputs (Level 2) such as SOFR rate curves, futures, volatilities and basis spreads (when applicable). The fair values of the foreign currency exchange contracts were derived by using Level 2 inputs based on observable spot and forward exchange rates in active markets. There has not been any impact to the fair value of derivative liabilities due to the Company's own credit risk. Similarly, there has not been any material impact to the fair value of derivative assets based on the Company's evaluation of counterparties' credit risks.

The estimated fair value of the Company’s term loans was based on information provided by the agent under the Company’s Credit Agreement. The estimated fair values of the Company’s notes were based upon quoted market prices.

The fair value of cash and cash equivalents, trade accounts receivable-net and accounts payable approximated carrying value due to the short-term nature of these instruments at December 30, 2023 and September 30, 2023.

10.    DERIVATIVES AND HEDGING ACTIVITIES

The Company is exposed to, among other things, the impact of changes in foreign currency exchange rates and interest rates in the normal course of business. The Company’s risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative financial instruments to offset a portion of these risks. The Company uses derivative financial instruments only to the extent necessary to hedge identified business risks and does not enter into such transactions for trading purposes. The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties. These derivative financial instruments do not subject the Company to undue risk, as gains and losses on these instruments generally offset gains and losses on the underlying assets, liabilities, or anticipated transactions that are being hedged. The Company has agreements with each of its swap, cap and collar counterparties that contain a provision whereby if the Company defaults on the Credit Agreement, the Company could also be declared in default on its swaps, cap and collars resulting in an acceleration of payment under the swaps, cap and collars.

All derivative financial instruments are recorded at fair value in the condensed consolidated balance sheets. For a derivative that has not been designated as an accounting hedge, the change in the fair value is recognized immediately through earnings. For a derivative that has been designated as an accounting hedge of an existing asset or liability (a fair value hedge), the change in the fair value of both the derivative and underlying asset or liability is recognized immediately through earnings. For a derivative designated as an accounting hedge of an anticipated transaction (a cash flow hedge), the change in the fair value is recorded on the condensed consolidated balance sheets in accumulated other comprehensive loss to the extent the derivative is effective in mitigating the exposure related to the anticipated transaction. The change in the fair value related to the ineffective portion of the hedge, if any, is immediately recognized in earnings. The amount recorded within accumulated other comprehensive loss is reclassified into earnings in the same period during which the underlying hedged transaction affects earnings.

Interest Rate Swap, Cap and Collar Agreements – Interest rate swap, cap and collar agreements are used to manage interest rate risk associated with floating rate borrowings under our Credit Agreement. These agreements involve the receipt of floating rate amounts in exchange for fixed rate interest payments over the term of the agreements without an exchange of the underlying principal amount. The agreements utilized by the Company effectively modify the Company’s exposure to interest rate risk by converting a portion of the Company’s floating rate debt to a fixed rate basis from the effective date through the maturity date of the respective interest rate swap, cap and collar agreements, thereby reducing the impact of interest rate movements on future interest expense.

16

During the second quarter of fiscal 2023, we entered into LIBOR to Term SOFR basis interest rate swap and cap transactions to effectively convert our existing swaps and cap from LIBOR-based to Term SOFR-based. The basis swaps and cap offset the LIBOR exposure of the existing swaps and cap and effectively fix the Term SOFR rate for the notional amount. We also entered into forward starting interest rate collar agreements during the second quarter of fiscal 2023. The interest rate collar agreements establish a range where we will pay the counterparties if the three-month Term SOFR rate falls below the established floor rate of 2.0%, and the counterparties will pay us if the three-month Term SOFR rate exceeds the ceiling rate of 3.5%. The collar will settle quarterly from the effective date through the maturity date. No payments or receipts will be exchanged on the interest rate collar contracts unless interest rates rise above or fall below the contracted ceiling or floor rates.

The tables below summarize the key terms of the swaps, cap and collars as of December 30, 2023 (aggregated by effective date).

Interest rate swap agreements:

Aggregate Notional Amount (in millions)	Effective Date	Maturity Date	Conversion of Related Variable Rate Debt subject to Term SOFR to Fixed Rate of:
$400	3/31/2023	6/28/2024	6.25% (3.0% plus the 3.25% margin percentage)
$900	3/31/2023	6/28/2024	6.35% (3.1% plus the 3.25% margin percentage)
$500	3/31/2023	3/31/2025	6.25% (3.0% plus the 3.25% margin percentage)
$1,500	3/31/2023	3/31/2025	6.35% (3.1% plus the 3.25% margin percentage)
$700	3/31/2023	9/30/2025	4.55% (1.3% plus the 3.25% margin percentage)

Interest rate cap agreement:

Aggregate Notional Amount (in millions)	Effective Date	Maturity Date	Offsets Variable Rate Debt Attributable to Fluctuations Above:
$700	3/31/2023	9/30/2025	Three-month Term SOFR rate of 1.25%

Interest rate collar agreements:

Aggregate Notional Amount (in millions)	Effective Date	Maturity Date	Offsets Variable Rate Debt Attributable to Fluctuations Below and Above:
$1,100	3/31/2025	9/30/2026	Three-month Term SOFR rate of 2.00% (floor) and 3.50% (cap)
$500	9/30/2025	9/30/2026	Three-month Term SOFR rate of 2.00% (floor) and 3.50% (cap)

These derivative instruments qualify as effective cash flow hedges under U.S. GAAP. For the LIBOR to Term SOFR basis interest rate swap and cap agreements referenced above, we applied the practical expedients permissible under ASC 848 to continue hedge accounting for our existing swaps and cap as effective cash flow hedges. For our cash flow hedges, the effective portion of the gain or loss from the financial instruments is initially reported as a component of accumulated other comprehensive loss in stockholders’ deficit and subsequently reclassified into earnings in the same line as the hedged item in the same period or periods during which the hedged item affects earnings. As the interest rate swap, cap and collar agreements are used to manage interest rate risk, any gains or losses from the derivative instruments that are reclassified into earnings are recognized in interest expense-net in the condensed consolidated statements of income. Cash flows related to the derivative contracts are included in cash flows from operating activities on the condensed consolidated statements of cash flows.

17

Certain derivative asset and liability balances are offset where master netting agreements provide for the legal right of setoff. For classification purposes, we record the net fair value of each type of derivative position that is expected to settle in less than one year with each counterparty as a net current asset or liability and each type of long-term position as a net non-current asset or liability. The amounts shown in the table below represent the gross amounts of recognized assets and liabilities, the amounts offset in the condensed consolidated balance sheets and the net amounts of assets and liabilities presented therein (in millions):

	December 30, 2023				September 30, 2023

(1)Refer to Note 9, “Fair Value Measurements,” for the condensed consolidated balance sheets classification of the Company's interest rate swap, cap and collar agreements.

Based on the fair value amounts determined as of December 30, 2023, the estimated net amount of existing (gains) losses and caplet amortization expected to be reclassified into interest expense-net within the next twelve months is approximately ($71) million.

Foreign Currency Forward Exchange Contracts – The Company transacts business in various foreign currencies, which subjects the Company’s cash flows and earnings to exposure related to changes in foreign currency exchange rates. These exposures arise primarily from purchases or sales of products and services from third parties. Foreign currency forward exchange contracts provide for the purchase or sale of foreign currencies at specified future dates at specified exchange rates, and are used to offset changes in the fair value of certain assets or liabilities or forecasted cash flows resulting from transactions denominated in foreign currencies. At December 30, 2023, the Company has outstanding foreign currency forward exchange contracts to sell U.S. dollars with notional amounts of $124 million. The maximum duration of the Company’s foreign currency cash flow hedge contracts at December 30, 2023 is nine months. These notional values consist of contracts for the Canadian dollar and the euro and are stated in U.S. dollar equivalents at spot exchange rates at the respective trade dates. Amounts related to foreign currency forward exchange contracts included in accumulated other comprehensive loss in stockholders' deficit are reclassified into net sales when the hedged transaction settles.

During the thirteen week period ended December 30, 2023, the losses reclassified on settlements of foreign currency forward exchange contracts designated as cash flow hedges into net sales was approximately $1 million. The losses were previously recorded as a component of accumulated other comprehensive loss in stockholders' deficit. As of December 30, 2023, the Company expects to record a net loss of less than $1 million on foreign currency forward exchange contracts designated as cash flow hedges to net sales over the next twelve months.

11.    SEGMENTS

The Company’s businesses are organized and managed in three reporting segments: Power & Control, Airframe and Non-aviation.

The Power & Control segment includes operations that primarily develop, produce and market systems and components that predominately provide power to or control power of the aircraft utilizing electronic, fluid, power and mechanical motion control technologies. Major product offerings include mechanical/electromechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices, specialized AC/DC electric motors and generators, batteries and chargers, databus and power controls, advanced sensor products, switches and relay panels, high performance hoists, winches and lifting devices, and cargo loading, handling and delivery systems. Primary customers of this segment are engine and power system and subsystem suppliers, airlines, third party maintenance suppliers, military buying agencies and repair depots. Products are sold in the original equipment and aftermarket market channels.

The Airframe segment includes operations that primarily develop, produce and market systems and components that are used in non-power airframe applications utilizing airframe and cabin structure technologies. Major product offerings include engineered latching and locking devices, engineered rods, engineered connectors and elastomer sealing solutions, cockpit security components and systems, specialized and advanced cockpit displays, engineered audio, radio and antenna systems, specialized lavatory components, seat belts and safety restraints, engineered and customized interior surfaces and related components, thermal protection and insulation, lighting and control technology, parachutes and specialized flight, wind tunnel and jet engine testing services and equipment. Primary customers of this segment are airframe manufacturers and cabin system suppliers and subsystem suppliers, airlines, third party maintenance suppliers, military buying agencies and repair depots. Products are sold in the original equipment and aftermarket market channels.

The Non-aviation segment includes operations that primarily develop, produce and market products for non-aviation markets. Major product offerings include seat belts and safety restraints for ground transportation applications, mechanical/electromechanical actuators and controls for space applications, hydraulic/electromechanical actuators and fuel valves for land-based gas turbines, and refueling systems for heavy equipment used in mining, construction and other industries and turbine controls for the energy and oil and gas markets. Primary customers of this segment are off-road vehicle suppliers and subsystem suppliers, child restraint system suppliers, satellite and space system suppliers, manufacturers of heavy equipment used in mining, construction and other industries and turbine original equipment manufacturers, gas pipeline builders and electric utilities.

The primary measurement used by management to review and assess the operating performance of each segment is EBITDA As Defined. The Company defines EBITDA As Defined as earnings before interest, taxes, depreciation and amortization plus certain non-operating items recorded as corporate expenses including non-cash compensation charges incurred in connection with the Company’s stock incentive or deferred compensation plans, foreign currency gains and losses, acquisition-integration costs, acquisition and divestiture transaction-related expenses, and refinancing costs. Acquisition and divestiture-related costs represent accounting adjustments to inventory associated with acquisitions of businesses and product lines that were charged to cost of sales when the inventory was sold; costs incurred to integrate acquired businesses and product lines into the Company’s operations, facility relocation costs and other acquisition-related costs; transaction-related costs for both acquisitions and divestitures comprising deal fees; legal, financial and tax diligence expenses and valuation costs that are required to be expensed as incurred and other acquisition accounting adjustments.

EBITDA As Defined is not a measurement of financial performance under U.S. GAAP. Although the Company uses EBITDA As Defined to assess the performance of its business and for various other purposes, the use of this non-GAAP financial measure as an analytical tool has limitations, and it should not be considered in isolation or as a substitute for analysis of the Company’s results of operations as reported in accordance with U.S. GAAP.

The Company’s segments are reported on the same basis used internally for evaluating performance and for allocating resources. The accounting policies for each segment are the same as those described in the summary of significant accounting policies in the Company’s consolidated financial statements. Intersegment sales and transfers are recorded at values based on market prices, which creates intercompany profit on intersegment sales or transfers that is eliminated in consolidation. Intersegment sales were immaterial for the periods presented below. Corporate consists of our corporate offices. Corporate expenses consist primarily of compensation, benefits, professional services and other administrative costs incurred by the corporate offices. Corporate assets consist primarily of cash and cash equivalents. Corporate expenses and assets reconcile reportable segment data to the consolidated totals. An immaterial amount of corporate expenses is allocated to the operating segments.

13.    LEASES

The Company leases certain manufacturing facilities, offices, land, equipment and vehicles. Such leases, some of which are noncancellable and, in many cases, include renewals, expire at various dates. Such options to renew are included in the lease term when it is reasonably certain that the option will be exercised. The Company’s lease agreements typically do not contain any significant residual value guarantees or restrictive covenants, and payments within certain lease agreements are adjusted periodically for changes in an index or rate.

The Company determines if an arrangement is a lease at inception. Operating lease assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. Lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The discount rate implicit within our leases is generally not determinable and therefore we determine the discount rate based on our incremental borrowing rate. The incremental borrowing rate for our leases is determined based on the lease term and the currency in which lease payments are made. The length of a lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. The Company made an accounting policy election to not recognize lease assets or liabilities for leases with a term of twelve months or less. Additionally, when accounting for leases, the Company combines payments for leased assets, related services and other components of a lease.

14.    COMMITMENTS AND CONTINGENCIES

During the ordinary course of business, the Company is from time to time threatened with, or may become a party to, legal actions and other proceedings. While the Company is currently involved in certain legal proceedings, it believes the results of these proceedings will not have a material adverse effect on its financial condition, results of operations, or cash flows.

DOD OIG Audit – TransDigm’s subsidiaries are periodically subject to pricing reviews and government buying agencies that purchase some of our subsidiaries’ products are periodically subject to audits by the Department of Defense (“DOD”) Office of Inspector General (“OIG”) with respect to prices paid for such products. In 2019, the DOD OIG received a congressional letter requesting a comprehensive review of TransDigm’s contracts with the DOD from January 2017 through June 2019 to identify whether TransDigm earned excess profits. This subsequently resulted in an audit by the DOD OIG in which the objective was to determine whether TransDigm’s business model impacted the DOD’s ability to pay fair and reasonable prices for spare parts. In December 2021, the OIG completed the audit and issued the related audit report. Despite the audit report making clear there was no wrongdoing by TransDigm, its businesses, or the DOD, the report recommended that TransDigm voluntarily refund at least $21 million in excess profit on 150 contracts subject to the audit.

TransDigm disagrees with many of the implications contained in the report, and objects to the use of arbitrary standards and analysis which render many areas of the report inaccurate and misleading. These include: (1) The report expressly acknowledges that it used arbitrary standards that are not applicable to the audited contracts and warns that its arbitrary standards should not be used in the future. The use of inapplicable standards results in flawed analysis and is misleading; (2) The report ignores significant real costs incurred by the business and contrary to law reports these costs as excess profit; (3) Despite data demonstrating that the DOD paid lower prices compared to the commercial prices for similar parts, the report did not conduct a price analysis and instead implies that the DOD negotiated prices were too high.

No loss contingency related to the voluntary refund request has been recorded as of December 30, 2023 as the Company has concluded that based on the current facts and circumstances, it's uncertain as to whether or not the requested voluntary refund will be made.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Forward-looking Statements

The following discussion of the Company’s financial condition and results of operations should be read together with TD Group’s condensed consolidated financial statements and the related notes included elsewhere in this Quarterly Report on Form 10-Q. References in this section to “TransDigm,” “the Company,” “we,” “us,” “our,” and similar references refer to TD Group, TransDigm Inc. and TransDigm Inc.’s subsidiaries, unless the context otherwise indicates.

This Quarterly Report on Form 10-Q contains both historical and “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and 27A of the Securities Act of 1933, as amended. All statements other than statements of historical fact included that address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements, including, in particular, the statements about our plans, objectives, strategies and prospects regarding, among other things, our financial condition, results of operations and business. We have identified some of these forward-looking statements with words like “believe,” “may,” “will,” “should,” “expect,” “intend,” “plan,” “predict,” “anticipate,” “estimate” or “continue” and other words and terms of similar meaning. These forward-looking statements may be contained throughout this Quarterly Report on Form 10-Q. These forward-looking statements are based on current expectations about future events affecting us and are subject to uncertainties and factors relating to, among other things, our operations and business environment, all of which are difficult to predict and many of which are beyond our control. Many factors mentioned in our discussion in this Quarterly Report on Form 10-Q, including the risks outlined under “Risk Factors,” will be important in determining future results. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we do not know whether our expectations will prove correct. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties, including the risks outlined under “Risk Factors,” will be important in determining future results. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we do not know whether our expectations will prove correct. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties, including those described under “Risk Factors” in this Quarterly Report on Form 10-Q. Since our actual results, performance or achievements could differ materially from those expressed in, or implied by, these forward-looking statements, we cannot give any assurance that any of the events anticipated by these forward-looking statements will occur or, if any of them does occur, what impact they will have on our business, results of operations and financial condition. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date they are made. We do not undertake any obligation to update these forward-looking statements or the risk factors contained in this Quarterly Report on Form 10-Q to reflect new information, future events or otherwise, except as may be required under federal securities laws.

Important factors that could cause actual results to differ materially from the forward-looking statements made in this Quarterly Report on Form 10-Q include but are not limited to: the sensitivity of our business to the number of flight hours that our customers’ planes spend aloft and our customers’ profitability, both of which are affected by general economic conditions; supply chain constraints; increases in raw material costs, taxes and labor costs that cannot be recovered in product pricing; failure to complete or successfully integrate acquisitions; our indebtedness; current and future geopolitical or other worldwide events, including, without limitation, wars or conflicts and public health crises; cybersecurity threats; risks related to the transition or physical impacts of climate change and other natural disasters or meeting sustainability-related voluntary goals or regulatory requirements; our reliance on certain customers; the United States (“U.S.”) defense budget and risks associated with being a government supplier including government audits and investigations; failure to maintain government or industry approvals; risks related to changes in laws and regulations, including increases in compliance costs; potential environmental liabilities; liabilities arising in connection with litigation; risks and costs associated with our international sales and operations; and other factors. Refer to Part II, Item 1A included in this Quarterly Report on Form 10-Q and to Part II, Item 1A of the Annual Report on Form 10-K for additional information regarding the foregoing factors that may affect our business.

Overview

We believe we are a leading global designer, producer and supplier of highly engineered proprietary aerospace components with significant aftermarket content. We seek to develop highly customized products to solve specific needs for aircraft operators and manufacturers. We attempt to differentiate ourselves based on engineering, service and manufacturing capabilities. We typically choose not to compete for non-proprietary “build to print” business because it frequently offers lower margins than proprietary products. We believe that our products have strong brand names within the industry and that we have a reputation for high quality, reliability and strong customer support. We believe we have achieved steady, long-term growth in sales and improvements in operating performance we believe that due to our competitive strengths and through execution of our value-driven operating strategy. More specifically, focusing our businesses on our value-driven operating strategy of obtaining profitable new business, carefully controlling the cost structure and pricing our highly engineered value-added products to fairly reflect the value we provide and the resources required to do so has historically resulted in improvements in gross profit and income from operations over the long-term.

24

Our business is well diversified due to the broad range of products that we offer to our customers. Our major product offerings, substantially all of which are ultimately provided to end-users in the aerospace industry, include mechanical/electromechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices, specialized AC/DC electric motors and generators, batteries and chargers, engineered latching and locking devices, engineered rods, engineered connectors and elastomer sealing solutions, databus and power controls, cockpit security components and systems, specialized and advanced cockpit displays, engineered audio, radio and antenna systems, specialized lavatory components, seat belts and safety restraints, engineered and customized interior surfaces and related components, advanced sensor products, switches and relay panels, thermal protection and insulation, lighting and control technology, parachutes, high performance hoists, winches and lifting devices, cargo loading, handling and delivery systems and specialized flight, wind tunnel and jet engine testing services and equipment. Each of our product offerings is composed of many individual products that are typically customized to meet the needs of a particular aircraft platform or customer.

For the first quarter of fiscal year 2024, we generated net sales of $1,789 million and net income attributable to TD Group of $382 million. EBITDA As Defined was $912 million, or 51.0% of net sales. Refer to the “Non-GAAP Financial Measures” section for certain information regarding EBITDA and EBITDA As Defined, including reconciliations of EBITDA and EBITDA As Defined to income from operations and net cash provided by operating activities.

In the first quarter of fiscal 2024, we continued to see a rebound in our commercial aerospace end markets from the COVID-19 pandemic and despite economic headwinds and are encouraged by the progression of the commercial aerospace market recovery to date, building off of the progress from fiscal 2023. Commercial air travel in domestic markets continues to lead the air traffic recovery with most domestic markets nearing, achieving or surpassing pre-pandemic air traffic levels. The pace of the international recovery has been slower than the domestic recovery and remains below pre-pandemic levels. However, international revenue passenger kilometers (“RPKs”), a metric used to measure air traffic demand, continues to make positive strides as countries, particularly those in Asia, have removed international traveler restrictions and there is pent-up demand for long-haul travel. Current industry consensus indicates that worldwide RPKs will recover or surpass calendar year 2019 (i.e., pre-pandemic levels) in calendar year 2024. Therefore, we expect the Company's commercial aerospace end markets to continue progressing the remainder of fiscal 2024 barring any significant disruptions or setbacks. In the first quarter of fiscal 2024, we experienced improved sales in the commercial original equipment manufacturer (“OEM”) sector primarily due to increased aircraft production by Boeing and Airbus. Aircraft production rates continue to lag pre-pandemic levels, mainly due to continued commercial OEM supply chain and production issues that are slowing the pace of new aircraft manufacturing. Airline demand for new aircraft is strong and both Boeing and Airbus have disclosed further planned OEM production rate increases for calendar 2024; however, we are monitoring the Federal Aviation Administration's recent halting of Boeing's planned MAX production increase due to Boeing's ongoing quality control issues.

The pace of U.S. government defense spending outlays and government funding reprioritization provides for uncertainty in the defense aerospace market. Beginning in the second half of fiscal 2023 and continuing into the first quarter of fiscal 2024, defense sales have increased compared to the comparable prior year period due to improving U.S. government defense spend outlays, which we are hopeful will continue in subsequent quarters. Department of Defense (“DOD”) budgets have also trended upwards; however, the ongoing conflicts between Russia and Ukraine and Israel and Hamas and potential impact on reprioritization of U.S. government defense spending and other ancillary impacts of these conflicts causes uncertainty.

The global supply chain and labor markets, though improving, continue to be disrupted. The disruption has resulted in delays in the availability of certain raw materials and increased freight costs, raw material costs and labor costs. Our business has been adversely affected, though not materially, and could continue to be adversely affected by disruptions in our ability to timely obtain raw materials and components from our suppliers in the quantities we require or on favorable terms. Although we believe in most cases that we could identify alternative suppliers, or alternative raw materials or component parts, the lengthy and expensive aviation authority and OEM certification processes associated with aerospace products could prevent efficient replacement of a supplier, raw material or component part.

Critical Accounting Policies and Estimates

The preparation and fair presentation of the consolidated unaudited interim financial statements and accompanying notes included in this report are the responsibility of management. The financial statements and footnotes have been prepared in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial statements and contain certain amounts that were based upon management’s best estimates, judgments and assumptions that were believed to be reasonable under the circumstances. On an ongoing basis, we evaluate the accounting policies and estimates used to prepare financial statements.

We believe this measure provides investors with a supplemental understanding of underlying sales trends by providing sales growth on a consistent basis. Refer to Note 2, “Acquisitions,” in the notes to the condensed consolidated financial statements included herein for further information on the Company's recent acquisitions activity.

The increase in organic sales of $328 million for the thirteen week period ended December 30, 2023 compared to the thirteen week period ended December 31, 2022 is primarily related to increases in defense sales ($149 million, an increase of 28.0%), commercial aftermarket sales ($101 million, an increase of 21.3%) and commercial OEM sales ($77 million, an increase of 24.9%). The increase in defense sales is primarily attributable to improving U.S. government defense spend outlays. The increase in commercial aftermarket sales is primarily attributable to the continued recovery in commercial air travel demand and the resulting higher flight hours and utilization of aircraft in the first quarter of fiscal 2024 compared to fiscal 2023, particularly internationally. The increase in commercial OEM sales is primarily attributable to the continued recovery in both narrow-body and wide-body aircraft production and deliveries.

The acquisition sales for the thirteen week period ended December 30, 2023 are attributable to Calspan Corporation (“Calspan”), which was acquired in the third quarter of fiscal 2023.

•Cost of Sales and Gross Profit. Cost of sales increased by $143 million, or 23.7%, to $747 million for the thirteen week period ended December 30, 2023 compared to $604 million for the thirteen week period ended December 31, 2022. Cost of sales and the related percentage of net sales for the thirteen week periods ended December 30, 2023 and December 31, 2022 were as follows (amounts in millions):

	Thirteen Week Periods Ended
	December 30, 2023			December 31, 2022			Change		% Change
Cost of sales - excluding costs below	$	732		$	592		$	140	23.6	%
% of net sales	40.9		%	42.4		%
Foreign currency losses	14			18			(4)		(22.2)	%

Total cost of sales	$	747		$	604		$	143	23.7	%
% of net sales	41.8		%	43.2		%
Gross profit (Net sales less Total cost of sales)	$	1,042		$	793		$	249	31.4	%
Gross profit percentage (Gross profit / Net sales)	58.2		%	56.8		%

28

Cost of sales during the thirteen week period ended December 30, 2023 decreased as a percentage of net sales despite increased inflationary pressures. This was primarily driven by the application of our three core value-driven operating strategy (obtaining profitable new business, continually improving our cost structure and providing highly engineered value-added products to customers) coupled with fixed overhead costs incurred being spread over a higher production volume. A favorable sales mix, specifically, higher commercial aftermarket sales as a percentage of net sales compared to commercial OEM net sales, also contributed to the gross profit as a percentage of net sales increasing by 1.4 percentage points to 58.2% for the thirteen week period ended December 30, 2023 from 56.8% for the thirteen week period ended December 31, 2022.

•Selling and Administrative Expenses. Selling and administrative expenses increased by $51 million to $220 million, or 12.3% of net sales, for the thirteen week period ended December 30, 2023 from $169 million, or 12.1% of net sales, for the thirteen week period ended December 31, 2022. Selling and administrative expenses and the related percentage of net sales for the thirteen week periods ended December 30, 2023 and December 31, 2022 were as follows (amounts in millions):

	Thirteen Week Periods Ended
	December 30, 2023			December 31, 2022			Change		% Change
Selling and administrative expenses - excluding costs below	$	175		$	138		$	37	26.8	%
% of net sales	9.8		%	9.9		%
Non-cash stock and deferred compensation expense	45			31			14		45.2	%
% of net sales	2.5		%	2.2		%
Total selling and administrative expenses	$	220		$	169		$	51	30.2	%
% of net sales	12.3		%	12.1		%

Selling and administrative expenses as a percentage of net sales for the thirteen week period ended December 30, 2023 are consistent with the thirteen week period ended December 31, 2022 despite the higher inflationary environment compared to a year ago due to continued strategic cost mitigation efforts. The increase in selling and administrative expenses is primarily a result of the Calspan acquisition in the third quarter of fiscal 2023 and higher net sales across our businesses. The increase in non-cash stock and deferred compensation expense is primarily attributable to the increase in the Black-Scholes fair value of the stock option grants impacting non-cash stock compensation expense. The increase in the Black-Scholes fair value is due to the appreciation of the stock price, which is a key assumption used to determine the Black-Scholes fair value.

•Amortization of Intangible Assets. Amortization of intangible assets was $35 million for the thirteen week period ended December 30, 2023 compared to $34 million for the thirteen week period ended December 31, 2022. The increase in amortization expense of $1 million was primarily due to the amortization expense recognized on intangible assets from the third quarter of fiscal 2023 acquisition of Calspan.

•Interest Expense-net. Interest expense-net includes interest on borrowings outstanding, amortization of debt issuance costs, original issue discount and premium, revolving credit facility fees, finance leases, interest income and the impact of interest rate swaps and caps designated and qualifying as cash flow hedges. Interest expense-net increased $14 million, or 4.9%, to $300 million for the thirteen week period ended December 30, 2023 from $286 million for the comparable thirteen week period in the prior fiscal year. The increase in interest expense-net was primarily due an increase in the base rates, i.e., Term Secured Overnight Financing Rate (“Term SOFR”) and London Inter-Bank Offered Rate (“LIBOR”), to the portion of our variable rate debt that is not hedged (refer to Note 10, "“Derivatives and Hedging Activities” for information on our hedges). This was partially offset by a $15 million increase in interest income. The weighted average interest rate for cash interest payments on total borrowings outstanding for the thirteen week period ended December 30, 2023 was 6.3% compared to 5.9% for the thirteen week period ended December 31, 2022.

•Refinancing Costs. No refinancing costs were incurred for the thirteen week period ended December 30, 2023. Refinancing costs of $4 million recorded for the thirteen week period ended December 31, 2022 were primarily related to third party fees incurred for the refinancing activity under Amendment No. 10, Loan Modification Agreement and Refinancing Facility Agreement (herein, “Amendment No. 10”), to the Second Amended and Restated Credit Agreement, dated June 4, 2014 (the “Credit Agreement”) completed during the first quarter of fiscal 2023.

•Other Income. Other income was $1 million for the thirteen week periods ended December 30, 2023 and December 31, 2022, respectively. The activity in both periods primarily relates to the non-service related components of benefit costs on the Company's benefit plans.

29

•Income Tax Provision. Income tax expense as a percentage of income before income taxes was approximately 21.7% for the thirteen week period ended December 30, 2023 compared to 23.9% for the thirteen week period ended December 31, 2022. The Company’s lower effective tax rate for the thirteen week period ended December 30, 2023 was primarily due was to a more significant discrete impact of excess tax benefits associated with share-based payments, partially offset by an increase in the valuation allowance applicable to the Company's net interest deduction limitation carryforward.

•Net Income Attributable to TD Group. Net income attributable to TD Group increased $154 million, or 67.5%, to $382 million for the thirteen week period ended December 30, 2023 compared to net income attributable to TD Group of $228 million for the thirteen week period ended December 31, 2022, primarily as a result of the factors referenced above.

•Earnings per Share. Basic and diluted earnings per share was $4.87 for the thirteen week period ended December 30, 2023 and $3.33 for the thirteen week period ended December 31, 2022. Net income attributable to TD Group for the thirteen week period ended December 30, 2023 of $382 million was decreased by dividend equivalent payments of $101 million, or $1.75 per share, resulting in net income applicable to TD Group common stockholders of $281 million, or $4.87 per share. Net income attributable to TD Group for the thirteen week period ended December 31, 2022 of $228 million was decreased by dividend equivalent payments of $38 million, or $0.67 per share, resulting in net income applicable to TD Group common stockholders of $190 million, or $3.33 per share.

Business Segments

•Segment Net Sales. Net sales by segment for the thirteen week periods ended December 30, 2023 and December 31, 2022 were as follows (amounts in millions):

	Thirteen Week Periods Ended
	December 30, 2023		% of Net Sales		December 31, 2022		% of Net Sales		Change		% Change
Power & Control	$	885	49.5	%	$	725	51.9	%	$	160	22.1	%
Airframe	862		48.2	%	637		45.6	%	225		35.3	%
Non-aviation	42		2.3	%	35		2.5	%	7		20.0	%
Net sales	$	1,789	100.0	%	$	1,397	100.0	%	$	392	28.1	%

Net sales for the Power & Control segment increased $160 million, an increase of 22.1%, for the thirteen week period ended December 30, 2023 compared to the thirteen week period ended December 31, 2022. The sales increase resulted primarily from increases in organic sales in defense ($81 million, an increase of 24.5%), commercial aftermarket ($51 million, an increase of 21.7%) and commercial OEM ($24 million, an increase of 17.4%). The increase in defense sales is primarily attributable to slowly improving U.S. government defense spend outlays. The increase in commercial aftermarket sales is primarily attributable to the continued recovery in commercial air travel demand and the resulting higher flight hours and utilization of aircraft in the first quarter of fiscal 2024 compared to fiscal 2023. The increase in commercial OEM sales is primarily attributable to the continued recovery in both narrow-body and wide-body aircraft production and deliveries.

Net sales for the Airframe segment increased $225 million, an increase of 35.3%, for the thirteen week period ended December 30, 2023 compared to the thirteen week period ended December 31, 2022. The sales increase resulted primarily from increases in organic sales in defense ($68 million, an increase of 34.4%), commercial OEM ($52 million, an increase of 30.0%) and commercial aftermarket ($49 million, an increase of 21.0%). The increase in defense sales, commercial OEM sales and commercial aftermarket sales for the Airframe segment is attributable to the same factors described in the paragraph above for the Power & Control segment. Acquisition sales were approximately $64 million for the thirteen week period ended December 30, 2023 due to the impact of the Calspan acquisition. Acquisition sales represent net sales from acquired businesses for the period up to one year subsequent to their respective acquisition date.

The change in Non-aviation net sales compared to the thirteen week period in the prior fiscal year was not material.

•EBITDA As Defined. Refer to “Non-GAAP Financial Measures” in this discussion and analysis for additional information and limitations regarding these non-GAAP financial measures, including a reconciliation to the comparable U.S. GAAP financial measure. EBITDA As Defined by segment for the thirteen week periods ended December 30, 2023 and December 31, 2022 were as follows (amounts in millions):

	Thirteen Week Periods Ended
	December 30, 2023		% of  Segment Net Sales			December 31, 2022		% of  Segment Net Sales			Change		% Change
Power & Control	$	509	57.5	%		$	401	55.3	%		$	108	26.9	%
Airframe	431		50.0	%		312		49.0	%		119		38.1	%

Total Company EBITDA As Defined	$	912	51.0	%	(1)	$	699	50.0	%	(1)	$	213	30.5	%

(1)Calculated as a percentage of consolidated net sales.

EBITDA As Defined for the Power & Control segment increased approximately $108 million, an increase of 26.9%, resulting from higher organic sales in the defense, commercial OEM and commercial aftermarket channels. Also contributing to the increase in EBITDA As Defined was the application of our three core value-driven operating strategy and positive leverage on our fixed overhead costs spread over a higher production volume despite the ongoing inflationary environment for freight, labor and certain raw materials.

EBITDA As Defined for the Airframe segment increased approximately $119 million, an increase of 38.1%. The increase in EBITDA as Defined for the Airframe segment is attributable to the same factors described in the paragraph above for the Power & Control segment. EBITDA As Defined for the Airframe segment from acquisitions was approximately $18 million due to the impact of the Calspan acquisition. EBITDA As Defined from acquisitions represents EBITDA As Defined from acquired businesses for the period up to one year subsequent to the respective acquisition date.

The change in Non-aviation EBITDA As Defined compared to the thirteen week period in the prior fiscal year was not material.

Corporate expenses consist primarily of compensation, benefits, professional services and other administrative costs incurred by the corporate offices. An immaterial amount of corporate expenses is allocated to the operating segments. The increase compared to the prior fiscal year is primarily attributable to the current fiscal year portion of the deferred compensation plan adopted in the fourth quarter of fiscal 2022 for certain members of non-executive management.

Liquidity and Capital Resources

We have historically maintained a capital structure comprising a mix of equity and debt financing. We vary our leverage both to optimize our equity return and to pursue acquisitions. We expect to meet our current debt obligations as they come due through internally generated funds from current levels of operations and/or through refinancing in the debt markets prior to the maturity dates of our debt.

Significant Transactions – First Quarter of Fiscal 2024

On November 9, 2023, TransDigm entered into a definitive agreement to acquire the Electron Device Business of CPI for approximately $1,385 million in cash. The acquisition, which is expected to close in fiscal 2024, is expected to be financed through existing cash on hand, inclusive of a portion of the cash proceeds from the new long-term debt issued in the first quarter of fiscal 2024 (further described below and in Note 7, "Debt").

On November 27, 2023, the Company paid a special cash dividend of $35.00 on each outstanding share of common stock and cash dividend equivalent payments on eligible vested options outstanding under its stock option plans. Total cash payments, funded by existing cash on hand, of special dividend and dividend equivalents, were approximately $2,020 million.

On November 28, 2023, the Company completed the issuance of $2,000 million in new senior debt ($1,000 million in 7.125% senior secured notes due 2031 and $1,000 million in Tranche J term loans), which is expected to be used to fund the acquisition of the Electron Device Business of CPI and for general corporate purposes.

On December 28, 2023, the Company drew the remaining $100 million available on its trade receivable securitization facility.

* * * * *

If the Company has excess cash, it generally prioritizes allocating the excess cash in the following manner: (1) capital spending at existing businesses, (2) acquisitions of businesses, (3) payment of a special dividend and/or repurchases of our common stock and (4) prepayment of indebtedness or repurchase of debt.

The Company’s ability to make scheduled interest payments on, or to refinance, the Company’s indebtedness, or to fund non-acquisition related capital expenditures and research and development efforts, will depend on the Company’s ability to generate cash in the future. This is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond its control.

The Company's objective is to maintain an allocation of at least 75% fixed rate and 25% variable rate debt thereby limiting its exposure to changes in near-term interest rates. Interest rate swaps, caps and collars used to hedge and offset, respectively, the variable interest rates on our term loans are further described in Note 10, “Derivatives and Hedging Activities,” in the notes to the condensed consolidated financial statements included herein. As of December 30, 2023, approximately 86% of our gross debt was fixed rate.

As of December 30, 2023, the Company has significant cash liquidity as illustrated in the table presented below (in millions):

	As of December 30, 2023
Cash and cash equivalents	$	4,135
Availability on revolving credit facility	756
Cash liquidity	$	4,891

We believe our significant cash liquidity will allow us to meet our anticipated funding requirements, including the funding of $1,385 million acquisition of the Electron Device Business of CPI. We expect to meet our short-term cash liquidity requirements (including interest obligations and capital expenditures) through net cash from operating activities, cash on hand and, if needed, draws on the revolving credit facility. Long-term cash liquidity requirements consist primarily of obligations under our long-term debt agreements. There is no maturity on any tranche of term loans or notes until March 2026.

32

In connection with the continued application of our three core value-driven operating strategy (obtaining profitable new business, continually improving our cost structure and providing highly engineered value-added products to customers), we expect our efforts will continue to generate strong margins and provide sufficient cash provided by operating activities to meet our interest obligations and liquidity needs. We believe our cash provided by operating activities and available borrowing capacity will enable us to make strategic business acquisitions, pay dividends to our shareholders and make opportunistic investments in our own stock, subject to any restrictions in our existing credit agreement and market conditions.

The Company may issue additional debt if prevailing market conditions are favorable to doing so. In addition, the Company may increase its borrowings in connection with acquisitions, if cash flow from operating activities becomes insufficient to fund current operations or for other short-term cash needs or for common stock repurchases or dividends. Our future leverage will also be impacted by the then current conditions of the credit markets.

Operating Activities. The Company generated $636 million of net cash from operating activities during the thirteen week period ended December 30, 2023 compared to $377 million during the thirteen week period ended December 31, 2022.

The change in accounts receivable during the thirteen week period ended December 30, 2023 was a source of cash of $94 million compared to a source of cash of $121 million during the thirteen week period ended December 31, 2022. The decrease in the source of cash of $27 million is primarily attributable to the timing of cash receipts. The Company continues to actively manage its accounts receivable, the related agings and collection efforts.

The change in inventories during the thirteen week period ended December 30, 2023 was a use of cash of $78 million compared to a use of cash of $89 million during the thirteen week period ended December 31, 2022. The decrease in the use of cash of $11 million is primarily driven by higher sales activity partially offset by increased purchasing from higher demand. The Company continues to actively and strategically manage inventory levels in response to the ongoing supply chain challenges.

The change in accounts payable during the thirteen week period ended December 30, 2023 was a use of cash of $21 million compared to a use of cash of $13 million during the thirteen week period ended December 31, 2022. The change is due to the timing of payments to suppliers.

Investing Activities. Net cash used in investing activities was $50 million during the thirteen week period ended December 30, 2023, consisting primarily of capital expenditures of $36 million and the acquisition of a certain product line for approximately $13 million.

Net cash used in investing activities was $41 million during the thirteen week period ended December 31, 2022, consisting of capital expenditures of $31 million and the remaining $10 million cash payment due for a certain product line acquired at the end of fiscal 2022.

Financing Activities. Net cash provided by financing activities was $67 million during the thirteen week period ended December 30, 2023. The source of cash was primarily attributable to the net proceeds from the issuance of Tranche J term loans of $988 million, net proceeds of $983 million from the completion of the 2031 Secured Notes offering, proceeds of $100 million drawn on the revolving credit facility and $52 million in proceeds from stock option exercises. This was primarily offset by dividend and dividend equivalent payments of $2,038 million and principal payments on Tranche H and Tranche I term loans of $16 million. For the Tranche J term loans, principal payments commence on March 31, 2024, in which $3 million will be paid on a quarterly basis up to the maturity date.

Net cash used in financing activities was $65 million during the thirteen week period ended December 31, 2022. The use of cash was primarily attributable to repayments on term loans of $1,739 million, which consists of the full repayment of existing Tranche G term loans and fees ($1,725 million) plus principal payments on Tranche E and Tranche F term loans ($14 million), and dividend equivalent payments of $38 million. This was partially offset by $1,690 million in proceeds of Tranche H term loans (replacing the Tranche G term loans) and $27 million in proceeds from stock option exercises.

Contractual Obligations

We have future obligations under various contracts relating to debt and interest payments, finance and operating leases, pension and post-retirement benefit plans and purchase obligations. During the thirteen week period ended December 30, 2023, other than the financing activity further described in Note 7, “Debt,” in the notes to the condensed consolidated financial statements included herein, there were no material changes to these obligations as reported in our Annual Report on Form 10-K for the fiscal year ended September 30, 2023.

Description of Senior Secured Term Loans and Indentures

Senior Secured Term Loans Facilities

On November 28, 2023, the Company entered into Amendment No. 13 and Incremental Term Loan Assumption Agreement (herein, “Amendment No. 13”) to the Credit Agreement. Under the terms of Amendment No. 13, the Company, among other things, issued $1,000 million in Tranche J term loans maturing February 28, 2031. The Tranche J term loans bear interest at a rate of adjusted Term Secured Overnight Financing Rate (“Term SOFR”) plus an applicable margin of 3.25%. The Tranche J term loans were issued at a discount of 0.25%, or approximately $3 million. The Tranche J term loans were fully drawn on November 28, 2023 and the other terms and conditions that apply to the Tranche J term loans are substantially the same as the terms and conditions that apply to the term loans immediately prior to Amendment No. 13.

As of December 30, 2023, TransDigm has $7,233 million in fully drawn term loans (the “Term Loans Facility”) and an $810 million revolving credit facility. The Term Loans Facility consists of three tranches of term loans as follows (aggregate principal amount disclosed is as of December 30, 2023):

Term Loans Facility	Aggregate Principal	Maturity Date	Interest Rate
Tranche H	$1,708 million	February 22, 2027	Term SOFR plus 3.25%
Tranche I	$4,525 million	August 24, 2028	Term SOFR plus 3.25%
Tranche J	$1,000 million	February 28, 2031	Term SOFR plus 3.25%

The Term Loans Facility requires quarterly aggregate principal payments of $19 million. The revolving commitments consist of two tranches which include up to $152 million of multicurrency revolving commitments. At December 30, 2023, the Company had $54 million in letters of credit outstanding and $756 million in borrowings available under the revolving commitments. Draws on the revolving commitments are subject to an interest rate of 2.50% per annum. The unused portion of the revolving commitments is subject to a fee of 0.5% per annum.

The interest rates per annum applicable to the Term Loans Facility under the Credit Agreement are, at TransDigm’s option, equal to either an alternate base rate or an adjusted Term SOFR for one, three or six-month interest periods chosen by TransDigm, in each case plus an applicable margin percentage. The adjusted Term SOFR related to the Term Loans Facility are not subject to a floor. Refer to Note 10, “Derivatives and Hedging Activities,” in the notes to the condensed consolidated financial statements included herein for information about how our interest rate swaps, cap and collar agreements are used to hedge and offset, respectively, the variable interest rate portion of our debt.

34

The Subordinated Notes and Secured Notes do not require principal payments prior to their maturity. Interest under the Subordinated Notes and Secured Notes are payable semi-annually. The Subordinated Notes represent our unsecured obligations ranking subordinate to our senior debt, as defined in the applicable indentures. The Secured Notes represent our secured obligations ranking equally to all existing and future senior debt, as defined in the applicable indentures. The Subordinated Notes and Secured Notes contain many of the restrictive covenants included in the Credit Agreement. TransDigm is in compliance with all of the covenants contained in the Subordinated Notes and Secured Notes.

Guarantor Information

The Subordinated Notes are subordinated to all of our existing and future senior secured debt, including indebtedness under TransDigm’s existing senior secured credit facilities, rank equally with all of our existing and future senior subordinated debt and rank senior to all of our future debt that is expressly subordinated to the Subordinated Notes. The Subordinated Notes are fully and unconditionally guaranteed on a senior subordinated unsecured basis by TD Group, TransDigm UK and TransDigm Inc.’s Domestic Restricted Subsidiaries (as defined in the applicable indentures). The table set forth in Exhibit 22 filed with this Form 10-Q details the primary obligors and guarantors. The guarantees of the Subordinated Notes are subordinated to all of the guarantors’ existing and future senior debt, rank equally with all of their existing and future senior subordinated debt and rank senior to all of their future debt that is expressly subordinated to the guarantees of the Subordinated Notes. The Subordinated Notes are structurally subordinated to all of the liabilities of TD Group’s non-guarantor subsidiaries.

The Secured Notes are senior secured debt of TransDigm and rank equally in right of payment with all of TransDigm’s existing and future senior secured debt, including indebtedness under TransDigm’s existing senior secured credit facilities, and are senior in right of payment to all of TransDigm’s existing and future senior subordinated debt, including the Subordinated Notes. The 2026 Secured Notes and the 2028 Secured Notes are guaranteed on a senior secured basis by TD Group, TransDigm UK and TransDigm Inc.’s Domestic Restricted Subsidiaries (as defined in the applicable indentures). The 2030 Secured Notes and the 2031 Secured Notes are guaranteed on a senior secured basis by TD Group and each of TransDigm Inc.’s direct and indirect Restricted Subsidiaries (as defined in the applicable indenture) that is a borrower or guarantor under TransDigm’s senior secured credit facilities or that issues or guarantees any capital markets indebtedness of TransDigm Inc. or any of the guarantors in an aggregate principal amount of at least $200 million. As of the date of this Form 10-Q, the guarantors of the 2030 Secured Notes and 2031 Secured Notes are the same as the guarantors of the 2026 Secured Notes and the 2028 Secured Notes. The table set forth in Exhibit 22 filed with this Form 10-Q details the primary obligors and guarantors. The guarantees of the Secured Notes rank equally in right of payment with all of the guarantors’ existing and future senior secured debt and are senior in right of payment to all of their existing and future senior subordinated debt. The Secured Notes are structurally subordinated to all of the liabilities of TransDigm’s non-guarantor subsidiaries.

Separate financial statements of TransDigm Inc. are not presented because the Subordinated Notes and Secured Notes are fully and unconditionally guaranteed on a senior subordinated unsecured basis (if Subordinated Notes) and senior secured basis (if Secured Notes) by TD Group, TransDigm UK and all of TransDigm Inc.'s Domestic Restricted Subsidiaries. TD Group has no significant operations or assets separate from its investment in TransDigm Inc.

The financial information presented is that of TD Group, TransDigm Inc. and the other Guarantors, which includes TransDigm UK, on a combined basis and the financial information of non-issuer and non-guarantor subsidiaries has been excluded. Intercompany balances and transactions between TD Group, TransDigm Inc. and the other Guarantors have been eliminated, and amounts due from, amounts due to, and transactions with non-issuer and non-guarantor subsidiaries have been presented separately.

Certain Restrictive Covenants in Our Debt Documents

The Credit Agreement and the Indentures governing the Notes and Secured Notes contain restrictive covenants that, among other things, limit the incurrence of additional indebtedness, the payment of special dividends, transactions with affiliates, asset sales, acquisitions, mergers and consolidations, liens and encumbrances, and prepayments of certain other indebtedness.

The restrictive covenants included in the Credit Agreement are subject to amendments executed periodically. The most recent amendment that impacted the restrictive covenants contained in the Credit Agreement is Amendment No. 11, executed on February 24, 2023.

Under the terms of the Credit Agreement, TransDigm is entitled, on one or more occasions, to request additional term loans or additional revolving commitments to the extent that the existing or new lenders agree to provide such incremental term loans or additional revolving commitments provided that, among other conditions, our consolidated net leverage ratio would be no greater than 7.25x and the consolidated secured net debt ratio would be no greater than 5.00x, in each case, after giving effect to such incremental term loans or additional revolving commitments.

If any such default occurs, the lenders under the Credit Agreement and the holders of the Notes and Secured Notes may elect to declare all outstanding borrowings, together with accrued interest and other amounts payable thereunder, to be immediately due and payable. The lenders under the Credit Agreement also have the right in these circumstances to terminate any commitments they have to provide further borrowings. In addition, following an event of default under the Credit Agreement, the lenders thereunder and the holders of the Secured Notes will have the right to proceed against the collateral granted to them to secure the debt, which includes our available cash, and they will also have the right to prevent us from making debt service payments on the Notes.

With the exception of the revolving credit facility, the Company has no maintenance covenants in its existing term loan and indenture agreements. Under the Credit Agreement, if the usage of the revolving credit facility exceeds 35%, or $284 million, of the total revolving commitments, the Company is required to maintain a maximum consolidated net leverage ratio of net debt to trailing four-quarter EBITDA As Defined of 7.25x as of the last day of the fiscal quarter.

As of December 30, 2023, the Company was in compliance with all of its debt covenants and expects to remain in compliance with its debt covenants in subsequent periods.

Trade Receivable Securitization Facility

During fiscal 2014, the Company established a trade receivable securitization facility (the “Securitization Facility”). The Securitization Facility effectively increases the Company’s borrowing capacity depending on the amount of the domestic operations’ trade accounts receivable. The Securitization Facility includes the right for the Company to exercise annual one year extensions as long as there have been no termination events as defined by the agreement. The Company uses the proceeds from the Securitization Facility as an alternative to other forms of debt, effectively reducing borrowing costs. The Securitization Facility is collateralized by substantially all of the Company’s domestic operations’ trade accounts receivable.

On July 25, 2023, the Company amended the Securitization Facility to, among other things, increase the borrowing capacity from $350 million to $450 million and extend the maturity date to July 25, 2024. During the first quarter of fiscal 2024, the Company drew the remaining $100 million available under the Securitization Facility. As of December 30, 2023, the Company has borrowed $450 million under the Securitization Facility, which is fully drawn, and bears interest at a rate of 1.6% plus Term SOFR. At December 30, 2023, the applicable interest rate was 6.99%. The Securitization Facility is collateralized by substantially all of the Company’s domestic operations’ trade accounts receivable.

Dividend and Dividend Equivalent Payments

During the first quarter of fiscal 2024, the Company announced that TD Group's Board of Directors authorized and declared a special cash dividend of $35.00 on each outstanding share of common stock and cash dividend equivalent payments on eligible vested options outstanding under its stock option plans. Pursuant to the Fourth Amended and Restated TransDigm Group Incorporated 2006 Stock Incentive Plan Dividend Equivalent Plan, the Amended and Restated 2014 Stock Option Plan Dividend Equivalent Plan and the 2019 Stock Option Plan Dividend Equivalent Plan, all of the vested options granted under the existing stock option plans, except for grants to the members of the Board of Directors, are entitled to certain cash dividend equivalent payments in the event of the declaration of a dividend by the Company. In fiscal 2022, all members of the Board of Directors executed amendments to their option agreements in which future dividend declarations result in a reduction of the strike price of their existing options instead of receiving cash dividend equivalent payments.

On November 27, 2023, the Company paid the special cash dividend of $35.00 on each outstanding share of common stock, totaling $1,937 million. Dividend equivalent payments are made during the Company's first fiscal quarter each year and also upon payment of any dividends declared within the current fiscal year. Total dividend equivalent payments in the first quarter of fiscal 2024 and 2023 were approximately $101 million, of which $18 million was accrued as of September 30, 2023 and the remaining $83 million was associated with the November 2023 $35.00 dividend declaration, and $38 million, respectively.

36

Any future declaration of special cash dividends on our common stock will be at the discretion of our Board of Directors and will depend upon our results of operations, earnings, capital requirements, financial condition, future prospects, contractual restrictions under the Credit Agreement and indentures governing the Notes, the availability of surplus under Delaware law and other factors deemed relevant by our Board of Directors. TD Group is a holding company and conducts all of its operations through direct and indirect subsidiaries. Unless TD Group receives dividends, distributions, advances, transfers of funds or other payments from our subsidiaries, TD Group will be unable to pay any dividends on our common stock in the future. The ability of any subsidiaries to take any of the foregoing actions is limited by the terms of our Term Loans Facility and indentures and may be limited by future debt or other agreements that we may enter into.

Off-Balance Sheet Arrangements

The Company utilizes letters of credit to back certain payment and performance obligations. Letters of credit are subject to limits based on amounts outstanding under the Company’s revolving credit facility. As of December 30, 2023, the Company had $54 million in letters of credit outstanding.

Non-GAAP Financial Measures

We present below certain financial information based on our EBITDA and EBITDA As Defined. References to “EBITDA” mean earnings before interest, taxes, depreciation and amortization, and references to “EBITDA As Defined” mean EBITDA plus, as applicable for each relevant period, certain adjustments as set forth in the reconciliations of net income to EBITDA and EBITDA As Defined and the reconciliations of net cash provided by operating activities to EBITDA and EBITDA As Defined presented below.

Neither EBITDA nor EBITDA As Defined is a measurement of financial performance under U.S. GAAP. We present EBITDA and EBITDA As Defined because we believe they are useful indicators for evaluating operating performance and liquidity.

Our management believes that EBITDA and EBITDA As Defined are useful as indicators of liquidity because securities analysts, investors, rating agencies and others use EBITDA to evaluate a company’s ability to incur and service debt. In addition, EBITDA As Defined is useful to investors because the revolving credit facility under our senior secured credit facility requires compliance under certain circumstances, on a pro forma basis, with a financial covenant that measures the ratio of the amount of our secured indebtedness to the amount of our Consolidated EBITDA defined in the same manner as we define EBITDA As Defined herein.

In addition to the above, our management uses EBITDA As Defined to review and assess the performance of the management team in connection with employee incentive programs and to prepare its annual budget and financial projections. Moreover, our management uses EBITDA As Defined to evaluate acquisitions.

Although we use EBITDA and EBITDA As Defined as measures to assess the performance of our business and for the other purposes set forth above, the use of these non-GAAP financial measures as analytical tools has limitations, and you should not consider any of them in isolation, or as a substitute for analysis of our results of operations as reported in accordance with U.S. GAAP. Some of these limitations are:

•neither EBITDA nor EBITDA As Defined reflects the significant interest expense, or the cash requirements, necessary to service interest payments on our indebtedness;

•although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and neither EBITDA nor EBITDA As Defined reflects any cash requirements for such replacements;

•the omission of the substantial amortization expense associated with our intangible assets further limits the usefulness of EBITDA and EBITDA As Defined;

•neither EBITDA nor EBITDA As Defined includes the payment of taxes, which is a necessary element of our operations; and

•EBITDA As Defined excludes the cash expense we have incurred to integrate acquired businesses into our operations, which is a necessary element of certain of our acquisitions.

Because of these limitations, EBITDA and EBITDA As Defined should not be considered as measures of discretionary cash available to us to invest in the growth of our business. Management compensates for these limitations by not viewing EBITDA or EBITDA As Defined in isolation and specifically by using other U.S. GAAP measures, such as net income, net sales and operating profit, to measure our operating performance. Neither EBITDA nor EBITDA As Defined is a measurement of financial performance under U.S. GAAP, and neither should be considered as an alternative to net income or cash flow from operations determined in accordance with U.S. GAAP. Our calculation of EBITDA and EBITDA As Defined may not be comparable to the calculation of similarly titled measures reported by other companies.

As of December 30, 2023, TD Group carried out an evaluation, under the supervision and with the participation of TD Group’s management, including its President, Chief Executive Officer and Director (Principal Executive Officer) and Chief Financial Officer (Principal Financial Officer), of the effectiveness of the design and operation of TD Group’s disclosure controls and procedures. Based upon that evaluation, the President, Chief Executive Officer and Director and Chief Financial Officer concluded that TD Group’s disclosure controls and procedures are effective to ensure that information required to be disclosed by TD Group in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified by the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to TD Group’s management, including its President, Chief Executive Officer and Director and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

There have been no changes in the Company’s internal control over financial reporting that occurred during the fiscal quarter ended December 30, 2023, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II: OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The Company is involved in various claims and legal actions arising in the ordinary course of business. SEC regulations require us to disclose certain information about environmental proceedings when a governmental authority is a party to the proceedings if we reasonably believe that such proceedings may result in monetary sanctions above a stated threshold. Pursuant to such regulations, the Company uses a threshold of $1 million or more for purposes of determining whether disclosure of any such proceedings is required as we believe matters under this threshold are not material to the Company. While the Company is currently involved in certain legal proceedings, it believes the results of these proceedings will not have a material adverse effect on its financial condition, results of operations, or cash flows.

Information with respect to our legal proceedings is contained in Note 14, “Commitments and Contingencies,” in the notes to the condensed consolidated financial statements included herein and Note 15, “Commitments and Contingencies,” in Part IV, Item 15. Exhibits and Financial Statement Schedules, of our Annual Report on Form 10-K for the fiscal year ended September 30, 2023, filed on November 9, 2023.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS: PURCHASES OF EQUITY SECURITIES BY THE ISSUER

On January 27, 2022, the Board of Directors of the Company authorized a new stock repurchase program to permit repurchases of its outstanding common stock not to exceed $2,200 million in the aggregate (the “$2,200 million stock repurchase program”), replacing the $650 million stock repurchase program previously authorized by the Board on November 8, 2017, subject to any restrictions specified in the Second Amended and Restated Credit Agreement dated as of June 4, 2014, and/or Indentures governing the Company's existing Notes. There is no expiration date for this program.

No repurchases were made under the program during the thirteen week period ended December 30, 2023. As of December 30, 2023, $1,288 million remains available for repurchase under the $2,200 million stock repurchase program.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

BASIS OF PRESENTATION

BASIS OF PRESENTATION

As used in this Quarterly Report on Form 10-Q, unless the context otherwise requires, the terms “Company”, “TD Group”, “TransDigm”, “we” or “us” refer to TransDigm Group Incorporated and its subsidiaries.

Principles of Consolidation

The financial information included herein is unaudited; however, the information reflects all adjustments (consisting of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s condensed consolidated financial statements for the interim periods presented. These financial statements and notes should be read in conjunction with the financial statements and related notes for the fiscal year ended September 30, 2023 included in TD Group’s Annual Report on Form 10-K filed on November 9, 2023. As disclosed therein, the Company’s annual consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”). The September 30, 2023 condensed consolidated balance sheet was derived from TD Group’s audited financial statements. The results of operations for the thirteen week period ended December 30, 2023 are not necessarily indicative of the results to be expected for the full year.

Reclassifications

Certain reclassifications have been made to the prior year amounts to conform to the current year presentation, none of which are material.

New Accounting Pronouncements Issued

In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” to amend certain disclosure and presentation requirements for a variety of topics within the ASC. These amendments align the requirements in the ASC to the removal of certain disclosure requirements set out in Regulation S-X and Regulation S-K, announced by the SEC. The effective date for each amended topic in the ASC is either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirements by that date. Early adoption is prohibited. The Company does not expect that the application of this standard will have an impact on our condensed consolidated financial statements and disclosures.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” ASU 2023-07 expands disclosures about a public business entity's reportable segments and provides for more detailed information about a reportable segment's expenses. Additionally, ASU 2023-07 requires all segment profit or loss and assets disclosures to be provided on an annual and interim basis. This standard is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning one year later. Early adoption is permitted. The Company is currently evaluating this standard to determine its impact on our disclosures.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires a public business entity to disclose specific categories in its annual effective tax rate reconciliation and disaggregated information about significant reconciling items by jurisdiction and by nature. The ASU also requires entities to disclose their income tax payments (net of refunds) to international, federal, and state and local jurisdictions. The standard makes several other changes to income tax disclosure requirements. This standard is effective for annual periods beginning after December 15, 2024, and requires prospective application with the option to apply it retrospectively. Early adoption is permitted. The Company is currently evaluating this standard to determine its impact on our disclosures.

As of December 30, 2023, the measurement period (not to exceed one year) is open; therefore, the assets acquired and liabilities assumed related to the Calspan acquisition are subject to adjustment until the end of the respective measurement period.

The Company is in the process of finalizing a third-party valuation of property, plant and equipment and certain intangible assets of Calspan. The allocation of the purchase price is preliminary and will likely change in future periods, perhaps materially, as fair value estimates of the assets acquired and liabilities assumed are finalized, including those related to deferred taxes and income taxes. We utilized both the cost and market approaches to value property, plant and equipment, which consider external transactions and other comparable transactions, estimated replacement and reproduction costs, and estimated useful lives and consideration for physical, functional and economic obsolescence. The fair values of acquired intangibles are determined based on an income approach, using estimates and assumptions that are deemed reasonable by the Company. Significant assumptions include the discount rates and certain assumptions that form the basis of the forecasted results of the acquired business including revenue, earnings before interest, taxes, depreciation and amortization (“EBITDA”), growth rates, royalty rates and technology obsolescence rates. These assumptions are forward looking and could differ from future economic and market conditions.

Pro forma net sales and results of operations for the Calspan acquisition had it occurred at the beginning of the thirteen week period ended December 31, 2022 are not material and, accordingly, are not provided.

The allocation of the estimated fair value of assets acquired and liabilities assumed in the Calspan acquisition as of the May 8, 2023 acquisition date, as well as measurement period adjustments recorded within the permissible one year measurement period, are summarized in the table below (in millions):

	Preliminary		Measurement Period		Adjusted Preliminary
	Allocation		Adjustments (2)		Allocation
Assets acquired (excluding cash):
Trade accounts receivable	$	39	$	—	$	39
Inventories	2		—		2
Prepaid expenses and other	40		—		40
Property, plant and equipment	105		278		383
Goodwill	367		(122)		245		(1)
Other intangible assets	243		(151)		92		(1)
Other non-current assets	7		—		7
Total assets acquired (excluding cash)	803		5		808
Liabilities assumed:

Accrued and other current liabilities	50		—		50
Deferred income taxes	8		5		13
Other non-current liabilities	6		—		6
Total liabilities assumed	74		4		78
Net assets acquired	$	729	$	1	$	730

(1)Of the approximately $245 million of goodwill recognized for the acquisition, the Company expects that approximately $218 million will be deductible for tax purposes. Of the approximately $92 million of other intangible assets recognized for the acquisition, the Company expects that approximately $86 million will be deductible for tax purposes. The goodwill and intangible assets are expected to be deductible over 15 years.

(2)Measurement period adjustments primarily related to the adjustments in the fair values of the acquired property, plant and equipment and other intangible assets from the third-party valuation. A substantial portion of the measurement period adjustments to property, plant and equipment relates to the fair value of the transonic wind tunnel. The offset to the measurement period adjustments was to goodwill.

Extant Aerospace Acquisitions – For the thirteen week period ended December 30, 2023, the Company's Extant Aerospace subsidiary, which is included within TransDigm’s Power & Control segment, completed an acquisition of substantially all of the assets and technical data rights of a certain product line, which met the definition of a business, for a total purchase price of $13 million. The allocation of the purchase price remains preliminary and will likely change, though not materially, in future periods up to the expiration of the respective one year measurement period as fair value estimates of the assets acquired and liabilities assumed are finalized. The Company expects that all of the approximately $6 million of goodwill and $3 million of other intangible assets recognized for the acquisition will be deductible for tax purposes over 15 years.

For the fiscal year ended September 30, 2023, the Company's Extant Aerospace subsidiary, completed a series of acquisitions of substantially all of the assets and technical data rights of certain product lines, each meeting the definition of a business, for a total purchase price of $24 million. The allocation of the purchase price remains preliminary and will likely change, though not materially, in future periods up to the expiration of the respective one year measurement period as fair value estimates of the assets acquired and liabilities assumed are finalized. The Company expects that all of the approximately $12 million of goodwill and $6 million of other intangible assets recognized for the acquisitions will be deductible for tax purposes over 15 years.

Pro forma net sales and results of operations for the Extant Aerospace product line acquisitions, had they occurred at the beginning of the thirteen week periods ended December 30, 2023 or December 31, 2022 are not material and, accordingly, are not provided.

The acquisitions completed by the Company strengthen and expand the Company’s position to design, produce and supply highly engineered proprietary aerospace components in niche markets with significant aftermarket content and provide opportunities to create value through the application of our three core value-driven operating strategy (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers). The purchase prices paid reflect the current EBITDA and cash flows, as well as the future EBITDA and cash flows expected to be generated by the businesses, which are driven in most cases by the recurring aftermarket consumption over the life of a particular aircraft, estimated to be approximately 25 to 30 years.

REVENUE RECOGNITION

3 Months Ended

Dec. 30, 2023

Revenue from Contract with Customer [Abstract]

REVENUE RECOGNITION

REVENUE RECOGNITION

TransDigm's sales are concentrated in the aerospace and defense industry. The Company’s customers include: distributors of aerospace components, commercial airlines, large commercial transport and regional and business aircraft original equipment manufacturers (“OEMs”), various armed forces of the U.S. and friendly foreign governments, defense OEMs, system suppliers, and various other industrial customers.

The Company recognizes revenue from contracts with customers using the five step model prescribed in ASC 606. A substantial portion of the Company's revenue is recorded at a point in time basis. Revenue is recognized from the sale of products or services when obligations under the terms of the contract are satisfied and control of promised goods or services have transferred to the customer. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services. Revenue is measured at the amount of consideration the Company expects to be paid in exchange for goods or services.

In certain contracts, control transfers to the customer over time, primarily in contracts where the customer is required to pay for the cost of both the finished and unfinished goods at the time of cancellation plus a reasonable profit relative to the work performed for products that were customized for the customer. Therefore, we recognize revenue over time for those agreements that have a right to margin and where the products being produced have no alternative use. 

Based on our production cycle, it is generally expected that goods related to the revenue will be shipped and billed within twelve months. For revenue recognized over time, we estimate the amount of revenue attributable to a contract earned at a given point during the production cycle based on certain costs, such as materials and labor incurred to date, plus the expected profit, which is a cost-to-cost input method.

We consider the contractual consideration payable by the customer and assess variable consideration that may affect the total transaction price. Variable consideration is included in the estimated transaction price when there is a basis to reasonably estimate the amount, including whether the estimate should be constrained in order to avoid a significant reversal of revenue in a future period. These estimates are based on historical experience, anticipated performance under the terms of the contract and our best judgment at the time.

When contracts are modified to account for changes in contract specifications and requirements, the Company considers whether the modification either creates new or changes the existing enforceable rights and obligations. Contract modifications that are for goods or services that are not distinct from the existing contract, due to the significant integration with the original good or service provided, are accounted for as if they were part of that existing contract. The effect of a contract modification to an existing contract on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct and at relative stand-alone selling price, they are accounted for as a new contract and performance obligation, which are recognized prospectively.

The Company’s payment terms vary by the type and location of the customer and the products or services offered. The Company does not offer any payment terms that would meet the requirements for consideration as a significant financing component.

Shipping and handling fees and costs incurred in connection with products sold are recorded in cost of sales in the consolidated statements of income, and are not considered a performance obligation to our customers.

The Company pays sales commissions that relate to contracts for products or services that are satisfied at a point in time or over a period of one year or less and are expensed as incurred. These costs are reported as a component of selling and administrative expenses in the condensed consolidated statements of income.

Contract Assets and Liabilities – Contract assets reflect revenue recognized and performance obligations satisfied in advance of customer billing or reimbursable costs related to a specific contract. Contract liabilities (Deferred revenue) relate to payments received in advance of the satisfaction of performance under the contract. We receive payments from customers based on the terms established in our contracts. The following table summarizes our contract assets and liabilities balances (in millions):

	December 30, 2023		September 30, 2023
Contract assets, current (1)	$	196	$	191
Contract assets, non-current (2)	—		1
Total contract assets	196		192
Contract liabilities, current (3)	92		79
Contract liabilities, non-current (4)	7		8
Total contract liabilities	99		87
Net contract assets	$	97	$	105

(1)Included in prepaid expenses and other on the condensed consolidated balance sheets.

(2)Included in other non-current assets on the condensed consolidated balance sheets.

(3)Included in accrued and other current liabilities on the condensed consolidated balance sheets.

(4)Included in other non-current liabilities on the condensed consolidated balance sheets.

The increase in the Company's total contract assets at December 30, 2023 compared to September 30, 2023 is primarily due to the timing and status of work in process and/or milestones of certain contracts. The increase in the Company's total contract liabilities at December 30, 2023 compared to September 30, 2023 is primarily due to the receipt of advance payments. For the thirteen week period ended December 30, 2023, the revenue recognized that was previously included in contract liabilities was approximately $9 million.

Refer to Note 11, “Segments,” for disclosures related to the disaggregation of revenue.

Allowance for Credit Losses – The Company's allowance for credit losses is the allowance for uncollectible accounts. The allowance for uncollectible accounts reduces the trade accounts receivable balance to the estimated net realizable value equal to the amount that is expected to be collected.

The Company’s method for developing its allowance for credit losses is based on historical write-off experience, the aging of receivables, an assessment of the creditworthiness of customers, economic conditions and other external market information and supportable forward-looking information. The allowance also incorporates a provision for the estimated impact of disputes with customers. All provisions for allowances for uncollectible accounts are included in selling and administrative expenses. The determination of the amount of the allowance for uncollectible accounts is subject to judgment and estimation by management. If circumstances change or economic conditions deteriorate or improve, the allowance for uncollectible accounts could increase or decrease.

As of December 30, 2023 and September 30, 2023, the allowance for uncollectible accounts was $33 million and $31 million, respectively. The allowance for uncollectible accounts is assessed individually at each operating unit by the operating unit’s management team.

Amendment No. 13 and Incremental Term Loan Assumption Agreement – On November 28, 2023, the Company entered into Amendment No. 13 and Incremental Term Loan Assumption Agreement (herein, “Amendment No. 13”) to the Second Amended and Restated Credit Agreement dated as of June 4, 2014 (the “Credit Agreement”). Under the terms of Amendment No. 13, the Company, among other things, issued $1,000 million in Tranche J term loans maturing February 28, 2031. The Tranche J term loans bear interest at a rate of adjusted Term Secured Overnight Financing Rate (“Term SOFR”) plus an applicable margin of 3.25%. The Tranche J term loans were issued at a discount of 0.25%, or approximately $3 million. The Tranche J term loans were fully drawn on November 28, 2023 and the other terms and conditions that apply to the Tranche J term loans are substantially the same as the terms and conditions that apply to the term loans immediately prior to Amendment No. 13. Principal payments commence on March 31, 2024, in which $3 million will be paid on a quarterly basis up to the maturity date.

The Company capitalized $10 million in debt issuance costs associated with the Tranche J term loans during the thirteen week period ended December 30, 2023.

Issuance of $1,000 million Senior Secured Notes due 2031 – On November 28, 2023, the Company entered into a purchase agreement in connection with a private offering of $1,000 million in aggregate principal amount of 7.125% senior secured notes due 2031 (the “2031 Secured Notes”) at an issue price of 99.25% of the principal amount, which represents an approximately $8 million discount. The 2031 Secured Notes were issued pursuant to an indenture, dated as of November 28, 2023, amongst TransDigm Inc., as issuer, TransDigm Group and the other subsidiaries of TransDigm Inc. named therein, as guarantors. The 2031 Secured Notes are guaranteed, on a senior secured basis, by TransDigm Group and each of TransDigm Inc.’s direct and indirect restricted subsidiaries that is a borrower or guarantor under TransDigm’s senior secured credit facilities or that issues or guarantees any capital markets indebtedness of TransDigm or any of the guarantors in an aggregate principal amount of at least $200 million. The 2031 Secured Notes and guarantees rank equally in right of payment with all of TransDigm’s and the guarantors’ existing and future senior indebtedness, senior in right of payment to any of TransDigm’s and the guarantors’ existing and future indebtedness that is, by its terms, expressly subordinated in right of payment to the 2031 Secured Notes and guarantees, and structurally subordinated to all of the liabilities of TransDigm’s non-guarantor subsidiaries.

The 2031 Secured Notes bear interest at a rate of 7.125% per annum, which accrues from November 28, 2023 and is payable in arrears on June 1 and December 1 of each year, commencing on June 1, 2024. The 2031 Secured Notes mature on December 1, 2031, unless earlier redeemed or repurchased, and are subject to the terms and conditions set forth in the indenture.

The Company capitalized $10 million in debt issuance costs associated with the 2031 Secured Notes during the thirteen week period ended December 30, 2023.

Trade Receivable Securitization Facility – The Company’s trade receivable securitization facility (the “Securitization Facility”) effectively increases the Company’s borrowing capacity depending on the amount of the domestic operations’ trade accounts receivable. The Securitization Facility includes the right for the Company to exercise annual one year extensions as long as there have been no termination events as defined by the agreement. The Company uses the proceeds from the Securitization Facility as an alternative to other forms of debt, effectively reducing borrowing costs.

On July 25, 2023, the Company amended the Securitization Facility to, among other things, increase the borrowing capacity from $350 million to $450 million and extend the maturity date to July 25, 2024. During the first quarter of fiscal 2024, the Company drew the remaining $100 million available under the Securitization Facility. As of December 30, 2023, the Company has borrowed $450 million under the Securitization Facility, which is fully drawn, and bears interest at a rate of 1.6% plus Term SOFR. At December 30, 2023, the applicable interest rate was 6.99%. The Securitization Facility is collateralized by substantially all of the Company’s domestic operations’ trade accounts receivable.

Government Refundable Advances – Government refundable advances consist of payments received from the Canadian government to assist in research and development related to commercial aviation. The requirement to repay this advance is based on year-over-year commercial aviation revenue growth for certain product lines at CMC Electronics, which is a wholly-owned subsidiary of TransDigm. As of December 30, 2023 and September 30, 2023, the outstanding balance of these advances was $21 million.

Obligations under Finance Leases – The Company leases certain buildings and equipment under finance leases. The present value of the minimum finance lease payments, net of the current portion, represents a balance of $254 million and $193 million at December 30, 2023 and September 30, 2023, respectively. The increase in the current fiscal year is attributable to certain new leases of facilities and amendments to previous agreements qualifying as lease modifications resulting in a change in classification from an operating lease to a finance lease. Refer to Note 13, “Leases,” for further disclosure of the Company's lease obligations.

INCOME TAXES

INCOME TAXES

At the end of each reporting period, TD Group makes an estimate of its annual effective income tax rate. The estimate used in the year-to-date period may change in subsequent periods.

During the thirteen week periods ended December 30, 2023 and December 31, 2022, the effective income tax rate was 21.7% and 23.9%, respectively. The Company’s lower effective income tax rate for the thirteen week period ended December 30, 2023, was primarily due to a more significant discrete impact of excess tax benefits associated with share-based payments. The Company's effective income tax rate for the thirteen week period ended December 30, 2023 was slightly higher than the federal statutory tax rate of 21% primarily due to an increase in the valuation allowance applicable to the Company's net interest deduction limitation carryforward, offset by the discrete impact of excess tax benefits associated with share-based payments.

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state, local and foreign jurisdictions. The Company is no longer subject to U.S. federal examinations for years before fiscal 2018. The Company is currently under examination for its federal income taxes in Canada for fiscal years 2013 through 2019, in France for fiscal years 2020 through 2022, and in Germany for fiscal years 2014 through 2019. In addition, the Company is subject to state income tax examinations for fiscal years 2015 and later.

Unrecognized tax benefits at December 30, 2023 and September 30, 2023, the recognition of which would have an impact on the effective tax rate for each fiscal year, amounted to $17 million. The Company classifies all income tax-related interest and penalties as income tax expense, which were not significant for the thirteen week periods ended December 30, 2023 and December 31, 2022. As of December 30, 2023 and September 30, 2023, the Company accrued $6 million for the potential payment of interest and penalties. Within the next twelve months, it is reasonably possible that unrecognized tax benefits could be reduced by approximately $6 million resulting from the resolution or closure of tax examinations. Any increase in the amount of unrecognized tax benefits within the next

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS

The following table presents our assets and liabilities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. The fair value hierarchy has three levels based on the reliability of the inputs used to determine fair value. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs (other than quoted prices) that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The following summarizes the carrying amounts and fair values of financial instruments (in millions):

The Company values its financial instruments using an industry standard market approach, in which prices and other relevant information are generated by market transactions involving identical or comparable assets or liabilities. No financial instruments were recognized or disclosed using unobservable inputs (i.e., Level 3).

The Company’s derivatives consist of interest rate swap, cap and collar agreements and foreign currency exchange contracts. The fair values of the interest rate swap, cap and collar agreements were derived by taking the net present value of the expected cash flows using observable market inputs (Level 2) such as SOFR rate curves, futures, volatilities and basis spreads (when applicable). The fair values of the foreign currency exchange contracts were derived by using Level 2 inputs based on observable spot and forward exchange rates in active markets. There has not been any impact to the fair value of derivative liabilities due to the Company's own credit risk. Similarly, there has not been any material impact to the fair value of derivative assets based on the Company's evaluation of counterparties' credit risks.

The estimated fair value of the Company’s term loans was based on information provided by the agent under the Company’s Credit Agreement. The estimated fair values of the Company’s notes were based upon quoted market prices.

The fair value of cash and cash equivalents, trade accounts receivable-net and accounts payable approximated carrying value due to the short-term nature of these instruments at December 30, 2023 and September 30, 2023.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

DERIVATIVES AND HEDGING ACTIVITIES

DERIVATIVES AND HEDGING ACTIVITIES

The Company is exposed to, among other things, the impact of changes in foreign currency exchange rates and interest rates in the normal course of business. The Company’s risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes derivative financial instruments to offset a portion of these risks. The Company uses derivative financial instruments only to the extent necessary to hedge identified business risks and does not enter into such transactions for trading purposes. The Company generally does not require collateral or other security with counterparties to these financial instruments and is therefore subject to credit risk in the event of nonperformance; however, the Company monitors credit risk and currently does not anticipate nonperformance by other parties. These derivative financial instruments do not subject the Company to undue risk, as gains and losses on these instruments generally offset gains and losses on the underlying assets, liabilities, or anticipated transactions that are being hedged. The Company has agreements with each of its swap, cap and collar counterparties that contain a provision whereby if the Company defaults on the Credit Agreement, the Company could also be declared in default on its swaps, cap and collars resulting in an acceleration of payment under the swaps, cap and collars.

All derivative financial instruments are recorded at fair value in the condensed consolidated balance sheets. For a derivative that has not been designated as an accounting hedge, the change in the fair value is recognized immediately through earnings. For a derivative that has been designated as an accounting hedge of an existing asset or liability (a fair value hedge), the change in the fair value of both the derivative and underlying asset or liability is recognized immediately through earnings. For a derivative designated as an accounting hedge of an anticipated transaction (a cash flow hedge), the change in the fair value is recorded on the condensed consolidated balance sheets in accumulated other comprehensive loss to the extent the derivative is effective in mitigating the exposure related to the anticipated transaction. The change in the fair value related to the ineffective portion of the hedge, if any, is immediately recognized in earnings. The amount recorded within accumulated other comprehensive loss is reclassified into earnings in the same period during which the underlying hedged transaction affects earnings.

Interest Rate Swap, Cap and Collar Agreements – Interest rate swap, cap and collar agreements are used to manage interest rate risk associated with floating rate borrowings under our Credit Agreement. These agreements involve the receipt of floating rate amounts in exchange for fixed rate interest payments over the term of the agreements without an exchange of the underlying principal amount. The agreements utilized by the Company effectively modify the Company’s exposure to interest rate risk by converting a portion of the Company’s floating rate debt to a fixed rate basis from the effective date through the maturity date of the respective interest rate swap, cap and collar agreements, thereby reducing the impact of interest rate movements on future interest expense.

During the second quarter of fiscal 2023, we entered into LIBOR to Term SOFR basis interest rate swap and cap transactions to effectively convert our existing swaps and cap from LIBOR-based to Term SOFR-based. The basis swaps and cap offset the LIBOR exposure of the existing swaps and cap and effectively fix the Term SOFR rate for the notional amount. We also entered into forward starting interest rate collar agreements during the second quarter of fiscal 2023. The interest rate collar agreements establish a range where we will pay the counterparties if the three-month Term SOFR rate falls below the established floor rate of 2.0%, and the counterparties will pay us if the three-month Term SOFR rate exceeds the ceiling rate of 3.5%. The collar will settle quarterly from the effective date through the maturity date. No payments or receipts will be exchanged on the interest rate collar contracts unless interest rates rise above or fall below the contracted ceiling or floor rates.

The tables below summarize the key terms of the swaps, cap and collars as of December 30, 2023 (aggregated by effective date).

Interest rate swap agreements:

Aggregate Notional Amount (in millions)	Effective Date	Maturity Date	Conversion of Related Variable Rate Debt subject to Term SOFR to Fixed Rate of:
$400	3/31/2023	6/28/2024	6.25% (3.0% plus the 3.25% margin percentage)
$900	3/31/2023	6/28/2024	6.35% (3.1% plus the 3.25% margin percentage)
$500	3/31/2023	3/31/2025	6.25% (3.0% plus the 3.25% margin percentage)
$1,500	3/31/2023	3/31/2025	6.35% (3.1% plus the 3.25% margin percentage)
$700	3/31/2023	9/30/2025	4.55% (1.3% plus the 3.25% margin percentage)

Interest rate cap agreement:

Aggregate Notional Amount (in millions)	Effective Date	Maturity Date	Offsets Variable Rate Debt Attributable to Fluctuations Above:
$700	3/31/2023	9/30/2025	Three-month Term SOFR rate of 1.25%

Interest rate collar agreements:

Aggregate Notional Amount (in millions)	Effective Date	Maturity Date	Offsets Variable Rate Debt Attributable to Fluctuations Below and Above:
$1,100	3/31/2025	9/30/2026	Three-month Term SOFR rate of 2.00% (floor) and 3.50% (cap)
$500	9/30/2025	9/30/2026	Three-month Term SOFR rate of 2.00% (floor) and 3.50% (cap)

These derivative instruments qualify as effective cash flow hedges under U.S. GAAP. For the LIBOR to Term SOFR basis interest rate swap and cap agreements referenced above, we applied the practical expedients permissible under ASC 848 to continue hedge accounting for our existing swaps and cap as effective cash flow hedges. For our cash flow hedges, the effective portion of the gain or loss from the financial instruments is initially reported as a component of accumulated other comprehensive loss in stockholders’ deficit and subsequently reclassified into earnings in the same line as the hedged item in the same period or periods during which the hedged item affects earnings. As the interest rate swap, cap and collar agreements are used to manage interest rate risk, any gains or losses from the derivative instruments that are reclassified into earnings are recognized in interest expense-net in the condensed consolidated statements of income. Cash flows related to the derivative contracts are included in cash flows from operating activities on the condensed consolidated statements of cash flows.

Certain derivative asset and liability balances are offset where master netting agreements provide for the legal right of setoff. For classification purposes, we record the net fair value of each type of derivative position that is expected to settle in less than one year with each counterparty as a net current asset or liability and each type of long-term position as a net non-current asset or liability. The amounts shown in the table below represent the gross amounts of recognized assets and liabilities, the amounts offset in the condensed consolidated balance sheets and the net amounts of assets and liabilities presented therein (in millions):

	December 30, 2023				September 30, 2023
	Asset		Liability		Asset		Liability
Interest rate cap agreement	$	39	$	1	$	53	$	1
Interest rate collar agreements	4		—		17		—
Interest rate swap agreements	95		3		144		3
Net derivatives as classified in the condensed consolidated balance sheets (1)	$	138	$	4	$	214	$	4

(1)Refer to Note 9, “Fair Value Measurements,” for the condensed consolidated balance sheets classification of the Company's interest rate swap, cap and collar agreements.

Based on the fair value amounts determined as of December 30, 2023, the estimated net amount of existing (gains) losses and caplet amortization expected to be reclassified into interest expense-net within the next twelve months is approximately ($71) million.

Foreign Currency Forward Exchange Contracts – The Company transacts business in various foreign currencies, which subjects the Company’s cash flows and earnings to exposure related to changes in foreign currency exchange rates. These exposures arise primarily from purchases or sales of products and services from third parties. Foreign currency forward exchange contracts provide for the purchase or sale of foreign currencies at specified future dates at specified exchange rates, and are used to offset changes in the fair value of certain assets or liabilities or forecasted cash flows resulting from transactions denominated in foreign currencies. At December 30, 2023, the Company has outstanding foreign currency forward exchange contracts to sell U.S. dollars with notional amounts of $124 million. The maximum duration of the Company’s foreign currency cash flow hedge contracts at December 30, 2023 is nine months. These notional values consist of contracts for the Canadian dollar and the euro and are stated in U.S. dollar equivalents at spot exchange rates at the respective trade dates. Amounts related to foreign currency forward exchange contracts included in accumulated other comprehensive loss in stockholders' deficit are reclassified into net sales when the hedged transaction settles.

During the thirteen week period ended December 30, 2023, the losses reclassified on settlements of foreign currency forward exchange contracts designated as cash flow hedges into net sales was approximately $1 million. The losses were previously recorded as a component of accumulated other comprehensive loss in stockholders' deficit. As of December 30, 2023, the Company expects to record a net loss of less than $1 million on foreign currency forward exchange contracts designated as cash flow hedges to net sales over the next twelve months.

Segment Reporting [Abstract]

SEGMENTS

SEGMENTS

The Company’s businesses are organized and managed in three reporting segments: Power & Control, Airframe and Non-aviation.

The Power & Control segment includes operations that primarily develop, produce and market systems and components that predominately provide power to or control power of the aircraft utilizing electronic, fluid, power and mechanical motion control technologies. Major product offerings include mechanical/electromechanical actuators and controls, ignition systems and engine technology, specialized pumps and valves, power conditioning devices, specialized AC/DC electric motors and generators, batteries and chargers, databus and power controls, advanced sensor products, switches and relay panels, high performance hoists, winches and lifting devices, and cargo loading, handling and delivery systems. Primary customers of this segment are engine and power system and subsystem suppliers, airlines, third party maintenance suppliers, military buying agencies and repair depots. Products are sold in the original equipment and aftermarket market channels.

The Airframe segment includes operations that primarily develop, produce and market systems and components that are used in non-power airframe applications utilizing airframe and cabin structure technologies. Major product offerings include engineered latching and locking devices, engineered rods, engineered connectors and elastomer sealing solutions, cockpit security components and systems, specialized and advanced cockpit displays, engineered audio, radio and antenna systems, specialized lavatory components, seat belts and safety restraints, engineered and customized interior surfaces and related components, thermal protection and insulation, lighting and control technology, parachutes and specialized flight, wind tunnel and jet engine testing services and equipment. Primary customers of this segment are airframe manufacturers and cabin system suppliers and subsystem suppliers, airlines, third party maintenance suppliers, military buying agencies and repair depots. Products are sold in the original equipment and aftermarket market channels.

The Non-aviation segment includes operations that primarily develop, produce and market products for non-aviation markets. Major product offerings include seat belts and safety restraints for ground transportation applications, mechanical/electromechanical actuators and controls for space applications, hydraulic/electromechanical actuators and fuel valves for land-based gas turbines, and refueling systems for heavy equipment used in mining, construction and other industries and turbine controls for the energy and oil and gas markets. Primary customers of this segment are off-road vehicle suppliers and subsystem suppliers, child restraint system suppliers, satellite and space system suppliers, manufacturers of heavy equipment used in mining, construction and other industries and turbine original equipment manufacturers, gas pipeline builders and electric utilities.

The primary measurement used by management to review and assess the operating performance of each segment is EBITDA As Defined. The Company defines EBITDA As Defined as earnings before interest, taxes, depreciation and amortization plus certain non-operating items recorded as corporate expenses including non-cash compensation charges incurred in connection with the Company’s stock incentive or deferred compensation plans, foreign currency gains and losses, acquisition-integration costs, acquisition and divestiture transaction-related expenses, and refinancing costs. Acquisition and divestiture-related costs represent accounting adjustments to inventory associated with acquisitions of businesses and product lines that were charged to cost of sales when the inventory was sold; costs incurred to integrate acquired businesses and product lines into the Company’s operations, facility relocation costs and other acquisition-related costs; transaction-related costs for both acquisitions and divestitures comprising deal fees; legal, financial and tax diligence expenses and valuation costs that are required to be expensed as incurred and other acquisition accounting adjustments.

EBITDA As Defined is not a measurement of financial performance under U.S. GAAP. Although the Company uses EBITDA As Defined to assess the performance of its business and for various other purposes, the use of this non-GAAP financial measure as an analytical tool has limitations, and it should not be considered in isolation or as a substitute for analysis of the Company’s results of operations as reported in accordance with U.S. GAAP.

The Company’s segments are reported on the same basis used internally for evaluating performance and for allocating resources. The accounting policies for each segment are the same as those described in the summary of significant accounting policies in the Company’s consolidated financial statements. Intersegment sales and transfers are recorded at values based on market prices, which creates intercompany profit on intersegment sales or transfers that is eliminated in consolidation. Intersegment sales were immaterial for the periods presented below. Corporate consists of our corporate offices. Corporate expenses consist primarily of compensation, benefits, professional services and other administrative costs incurred by the corporate offices. Corporate assets consist primarily of cash and cash equivalents. Corporate expenses and assets reconcile reportable segment data to the consolidated totals. An immaterial amount of corporate expenses is allocated to the operating segments.

The following table presents net sales by reportable segment (in millions):

Leases

LEASES

The Company leases certain manufacturing facilities, offices, land, equipment and vehicles. Such leases, some of which are noncancellable and, in many cases, include renewals, expire at various dates. Such options to renew are included in the lease term when it is reasonably certain that the option will be exercised. The Company’s lease agreements typically do not contain any significant residual value guarantees or restrictive covenants, and payments within certain lease agreements are adjusted periodically for changes in an index or rate.

The Company determines if an arrangement is a lease at inception. Operating lease assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. Lease assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. The discount rate implicit within our leases is generally not determinable and therefore we determine the discount rate based on our incremental borrowing rate. The incremental borrowing rate for our leases is determined based on the lease term and the currency in which lease payments are made. The length of a lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. The Company made an accounting policy election to not recognize lease assets or liabilities for leases with a term of twelve months or less. Additionally, when accounting for leases, the Company combines payments for leased assets, related services and other components of a lease.

COMMITMENTS AND CONTINGENCIES

COMMITMENTS AND CONTINGENCIES

During the ordinary course of business, the Company is from time to time threatened with, or may become a party to, legal actions and other proceedings. While the Company is currently involved in certain legal proceedings, it believes the results of these proceedings will not have a material adverse effect on its financial condition, results of operations, or cash flows.

DOD OIG Audit – TransDigm’s subsidiaries are periodically subject to pricing reviews and government buying agencies that purchase some of our subsidiaries’ products are periodically subject to audits by the Department of Defense (“DOD”) Office of Inspector General (“OIG”) with respect to prices paid for such products. In 2019, the DOD OIG received a congressional letter requesting a comprehensive review of TransDigm’s contracts with the DOD from January 2017 through June 2019 to identify whether TransDigm earned excess profits. This subsequently resulted in an audit by the DOD OIG in which the objective was to determine whether TransDigm’s business model impacted the DOD’s ability to pay fair and reasonable prices for spare parts. In December 2021, the OIG completed the audit and issued the related audit report. Despite the audit report making clear there was no wrongdoing by TransDigm, its businesses, or the DOD, the report recommended that TransDigm voluntarily refund at least $21 million in excess profit on 150 contracts subject to the audit.

TransDigm disagrees with many of the implications contained in the report, and objects to the use of arbitrary standards and analysis which render many areas of the report inaccurate and misleading. These include: (1) The report expressly acknowledges that it used arbitrary standards that are not applicable to the audited contracts and warns that its arbitrary standards should not be used in the future. The use of inapplicable standards results in flawed analysis and is misleading; (2) The report ignores significant real costs incurred by the business and contrary to law reports these costs as excess profit; (3) Despite data demonstrating that the DOD paid lower prices compared to the commercial prices for similar parts, the report did not conduct a price analysis and instead implies that the DOD negotiated prices were too high.

No loss contingency related to the voluntary refund request has been recorded as of December 30, 2023 as the Company has concluded that based on the current facts and circumstances, it's uncertain as to whether or not the requested voluntary refund will be made.

Quarterly Financial Information Disclosure [Abstract]

Principles of Consolidation

Principles of Consolidation

The financial information included herein is unaudited; however, the information reflects all adjustments (consisting of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s condensed consolidated financial statements for the interim periods presented. These financial statements and notes should be read in conjunction with the financial statements and related notes for the fiscal year ended September 30, 2023 included in TD Group’s Annual Report on Form 10-K filed on November 9, 2023. As disclosed therein, the Company’s annual consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“U.S. GAAP”). The September 30, 2023 condensed consolidated balance sheet was derived from TD Group’s audited financial statements. The results of operations for the thirteen week period ended December 30, 2023 are not necessarily indicative of the results to be expected for the full year.

Certain reclassifications have been made to the prior year amounts to conform to the current year presentation, none of which are material.

New Accounting Pronouncements Issued

New Accounting Pronouncements Issued

In October 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-06, “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative,” to amend certain disclosure and presentation requirements for a variety of topics within the ASC. These amendments align the requirements in the ASC to the removal of certain disclosure requirements set out in Regulation S-X and Regulation S-K, announced by the SEC. The effective date for each amended topic in the ASC is either the date on which the SEC’s removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, or on June 30, 2027, if the SEC has not removed the requirements by that date. Early adoption is prohibited. The Company does not expect that the application of this standard will have an impact on our condensed consolidated financial statements and disclosures.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” ASU 2023-07 expands disclosures about a public business entity's reportable segments and provides for more detailed information about a reportable segment's expenses. Additionally, ASU 2023-07 requires all segment profit or loss and assets disclosures to be provided on an annual and interim basis. This standard is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning one year later. Early adoption is permitted. The Company is currently evaluating this standard to determine its impact on our disclosures.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires a public business entity to disclose specific categories in its annual effective tax rate reconciliation and disaggregated information about significant reconciling items by jurisdiction and by nature. The ASU also requires entities to disclose their income tax payments (net of refunds) to international, federal, and state and local jurisdictions. The standard makes several other changes to income tax disclosure requirements. This standard is effective for annual periods beginning after December 15, 2024, and requires prospective application with the option to apply it retrospectively. Early adoption is permitted. The Company is currently evaluating this standard to determine its impact on our disclosures.
