TRANSDIGM GROUP INCORPORATED

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

THIRTEEN WEEK PERIODS ENDED JANUARY 1, 2022 AND JANUARY 2, 2021

(UNAUDITED)

1.    DESCRIPTION OF THE BUSINESS

2.    UNAUDITED INTERIM FINANCIAL INFORMATION

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, 2021 included in TD Group’s Form 10-K filed on November 16, 2021. 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, 2021 condensed consolidated balance sheet was derived from TD Group’s audited financial statements. The results of operations for the thirteen week period ended January 1, 2022 are not necessarily indicative of the results to be expected for the full year.

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

3.    ACQUISITIONS AND DIVESTITURES

Acquisitions

Cobham Aero Connectivity – On November 24, 2020, the Company entered into a definitive agreement to acquire all the outstanding stock of Chelton Limited, Chelton Avionics Holdings, Inc. and Mastsystem Int'l Oy, collectively, Cobham Aero Connectivity (“CAC”), for a total purchase price of $945 million. The acquisition was substantially completed on January 5, 2021 and financed through existing cash on hand. The Company completed the remainder of the acquisition of CAC on February 12, 2021, also through existing cash on hand. CAC operates from two primary facilities (Marlow, United Kingdom and Prescott, Arizona) and is a leading provider of highly engineered antennas and radios for the aerospace end market. The products are primarily proprietary with significant aftermarket content and have a strong presence across major defense platforms as well as select commercial applications. CAC's operating results are included within TransDigm's Airframe segment.

The acquisition strengthens and expands 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 strategies (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers). The purchase price paid for the acquisition reflects the current earnings before interest, taxes, depreciation and amortization (“EBITDA”) and cash flows, as well as the future EBITDA and cash flows expected to be generated by the business, 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.

6

The Company accounted for the CAC acquisition using the acquisition method of accounting and third-party valuation appraisals and included the results of operations of the acquisition in its condensed consolidated financial statements from the effective dates of the acquisition. The total purchase price of CAC was allocated to the underlying assets acquired and liabilities assumed based upon the respective fair value at the dates of acquisition. To the extent the purchase price exceeded the fair value of the net identifiable tangible and intangible assets acquired, such excess was allocated to goodwill. The fair values of acquired intangibles and certain liabilities, such as loss contract reserves, are determined based on estimates and assumptions that are deemed reasonable by the Company. Significant assumptions used to determine the fair values of acquired intangible assets include the discount rates and certain assumptions that form the basis of the forecasted results of the acquired business including revenue growth rates, EBITDA margins, royalty rates and technology obsolescence rates. Significant assumptions used to determine the fair value of the loss contract reserves using the discounted cash flow model include discount rates and forecasted costs to be incurred under the long-term contracts and at-market bid prices for respective contracts. These assumptions are forward looking and could be affected by future economic and market conditions.

Pro forma net sales and results of operations for the acquisition had it occurred at the beginning of the applicable thirteen week period ended January 1, 2022 or January 2, 2021 are not material and, accordingly, are not provided.

The final allocation of the fair value of assets acquired and liabilities assumed in the CAC acquisition as of the acquisition date, as well as measurement period adjustments recorded as of January 1, 2022, are summarized in the table below (in millions):

	Preliminary Allocation		Measurement Period Adjustments			Final Allocation
Assets acquired (excluding cash):
Trade accounts receivable	$	31	$	1		$	32
Inventories	27		2			29
Prepaid expenses and other	10		(3)			7
Property, plant and equipment	18		3			21
Goodwill	636		61			697		(1)
Other intangible assets	309		15			324		(1)
Other	34		(3)			31
Total assets acquired (excluding cash)	1,065		76			1,141
Liabilities assumed:
Accounts payable	15		3			18
Accrued and other current liabilities	38		6		(2)	44
Deferred income taxes	38		(7)			31
Other non-current liabilities	29		74		(2)	103
Total liabilities assumed	120		76			196
Net assets acquired	$	945	$	—		$	945

(1)Of the approximately $697 million of goodwill recognized for the acquisition, approximately $65 million is deductible for tax purposes. Of the approximately $324 million of other intangible assets recognized for the acquisition, approximately $105 million is deductible for tax purposes. The goodwill and intangible assets are deductible over 15 years.

(2)Primarily relates to the recording of loss contract reserves associated with acquired ongoing long-term contracts with customers that were incurring negative gross margins as of the date of acquisition. Based on our review of these contracts, we concluded that the terms of certain contracts were unfavorable when compared to market terms as of the acquisition date. The loss contract reserves, totaling $80.6 million, will be released over an estimated three to five year period.

Divestitures

ScioTeq and TREALITY Simulation Visual Systems – On June 30, 2021, TransDigm completed the divestiture of its ScioTeq and TREALITY Simulation Visual Systems businesses (“ScioTeq and TREALITY”) to OpenGate Capital for approximately $200 million in cash. ScioTeq and TREALITY were acquired by TransDigm as part of its acquisition of Esterline Technologies Corporation (“Esterline”) in March 2019 and were included in TransDigm’s Airframe segment. Neither ScioTeq or TREALITY met the criteria to be classified as held for sale as of January 2, 2021.

7

Technical Airborne Components – On April 27, 2021, TransDigm completed the divestiture of the Technical Airborne Components business (“TAC”) to Searchlight Capital Partners for approximately $40 million in cash. TAC was included in TransDigm’s Airframe segment. TAC did not meet the criteria to be classified as held for sale as of January 2, 2021.

The net gain on sale recognized in fiscal 2021 as a result of the ScioTeq and TREALITY and TAC divestitures was approximately $68 million, which was classified as a component of gain on sale of businesses-net within the condensed consolidated statements of income during the third quarter of fiscal 2021.

Racal Acoustics – On January 29, 2021, TransDigm completed the divestiture of the Racal Acoustics business (“Racal”) to Invisio Communications AB (“Invisio”) for approximately $20 million in cash. During the first quarter of fiscal 2021, the Company determined Racal met the criteria to be classified as held for sale. Therefore, the assets and liabilities of Racal, which were not material, have been presented as held for sale in other assets, accrued and other current liabilities and other non-current liabilities, respectively, in the condensed consolidated balance sheets as of January 2, 2021. Racal was acquired by TransDigm as part of its acquisition of Esterline in March 2019 and was included in TransDigm's Non-aviation segment.

Avista, Inc. – On November 17, 2020, TransDigm completed the divestiture of the Avista, Inc. business (“Avista”) to Belcan, LLC (“Belcan”) for approximately $8 million in cash. Avista was acquired by TransDigm as part of its acquisition of Esterline in March 2019 and was included in TransDigm's Airframe segment. The gain on sale recognized in the first quarter of fiscal 2021 as a result of the divestiture was immaterial and classified as a component of gain on sale of businesses-net within the condensed consolidated statements of income.

Souriau-Sunbank Connection Technologies – On December 20, 2019, TransDigm completed the divestiture of the Souriau-Sunbank Connection Technologies business (“Souriau-Sunbank”) to Eaton Corporation plc (“Eaton”) for approximately $920 million. Souriau-Sunbank was acquired by TransDigm as part of its acquisition of Esterline in March 2019 and was included in TransDigm's Non-aviation segment. During the first quarter of fiscal 2022, the Company received approximately $1 million from Eaton related to a final working capital settlement from the Souriau-Sunbank divestiture. These proceeds are classified as income from discontinued operations, net of tax, in the condensed consolidated statements of income.

4.    RECENT ACCOUNTING PRONOUNCEMENTS

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Accounting Standards Codification (“ASC”) 740) - Simplifying the Accounting for Income Taxes,” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company adopted ASU 2019-12 on October 1, 2021. The adoption of this standard did not have a material impact on our condensed consolidated financial statements and disclosures.

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform." Certain amendments were provided for in ASU 2021-01, “Reference Rate Reform (ASC 848): Scope,” which was issued in January 2021. This ASU provides optional guidance for a limited period of time to ease potential accounting impacts associated with transitioning away from reference rates that are expected to be discontinued, such as the London Interbank Offered Rate (“LIBOR”). The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The amendments in this ASU are effective through December 31, 2022. The Company is currently evaluating the impact of adopting this standard on our condensed consolidated financial statements and disclosures and we continue to monitor any subsequent updates impacting the transition.

5.    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 OEMs, various armed forces of the United States and friendly foreign governments, defense OEMs, system suppliers, and various other industrial customers.

The majority of the Company's revenue is recorded at a point in time. Revenue is recognized from the sale of products when control transfers to the customer, which is demonstrated by our right to payment, a transfer of title, a transfer of the risk and rewards of ownership, or the customer acceptance, but most frequently upon shipment where the customer obtains physical possession of the goods.

In some 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 the current year. 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 condensed 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 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):

(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.

For the thirteen week period ended January 1, 2022, the revenue recognized that was previously included in contract liabilities was not material.

Refer to Note 13, “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. All provisions for allowances for uncollectible accounts are included in selling and administrative expenses.

As of January 1, 2022 and September 30, 2021, the allowance for uncollectible accounts was $30 million. The allowance for uncollectible accounts is assessed individually at each operating unit by the operating unit’s management team.

Accrued interest, which is classified as a component of accrued and other current liabilities on the condensed consolidated balance sheets, was $172 million and $191 million as of January 1, 2022 and September 30, 2021, respectively.

Amendment No. 9 and Loan Modification Agreement – On December 29, 2021, the Company entered into Amendment No. 9 and Incremental Revolving Credit Assumption Agreement (herein, “Amendment No. 9”) to the Second Amended and Restated Credit Agreement dated as of June 4, 2014 (the “Credit Agreement”), which increases the capacity under the revolving credit facility from $760 million to $810 million. The terms and conditions that apply to Amendment No. 9 are the same as the terms and conditions that apply to the existing dollar revolving commitments and term loans under the Credit Agreement. As of January 1, 2022, the borrowings available under the revolving commitments were $776.5 million.

The Company capitalized $0.2 million representing debt issuance costs associated with Amendment No. 9 during the thirteen week period ended January 1, 2022.

Revolving Credit Facility – On October 6, 2021, the Company repaid $200 million previously drawn on the revolving credit facility, in addition to $0.1 million of accrued interest.

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 January 1, 2022 and September 30, 2021, the outstanding balance of these advances was $28 million and $29 million, respectively.

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 $128 million and $100 million at January 1, 2022 and September 30, 2021, respectively. Refer to Note 16, “Leases,” for further disclosure of the Company's lease obligations.

10.    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 January 1, 2022 and January 2, 2021, the effective income tax rate was 15.7% and 5.5%, respectively. The Company’s higher effective tax rate for the thirteen week period ended January 1, 2022 was primarily due to the ratio of the discrete impact of excess tax benefits from share-based payments to income from continuing operations being lower in the thirteen week period ended January 1, 2022 resulting from an increase in income from continuing operations before income taxes for the same thirteen week period. The Company’s effective income tax rate of 15.7% for the thirteen week period ended January 1, 2022 was lower than the federal statutory tax rate of 21%, primarily due to the discrete impact of excess tax benefits associated with share-based payments during the first quarter of fiscal 2022.

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 2017. The Company is currently under examination for its federal income taxes in Canada for fiscal years 2013 through 2019, in France for fiscal years 2018 through 2019 and in Germany for fiscal years 2014 through 2017. The Company expects the examinations in France to be completed during fiscal 2022. In addition, the Company is subject to state income tax examinations for fiscal years 2015 and later.

Unrecognized tax benefits at January 1, 2022 and September 30, 2021, the recognition of which would have an impact on the effective tax rate for each fiscal year, amounted to $18.5 million and $19.1 million, respectively. The Company classifies all income tax-related interest and penalties as income tax expense, which were not material for the thirteen week periods ended January 1, 2022 and January 2, 2021. As of January 1, 2022 and September 30, 2021, the Company accrued $4.9 million, respectively, for the potential payment of interest and penalties. Within the next 12 months, it is reasonably possible that unrecognized tax benefits could be reduced by approximately $3.8 million. Any increase in the amount of unrecognized tax benefits within the next 12 months is not expected to be material.

11.    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):

		January 1, 2022				September 30, 2021
	Level	Carrying Amount		Fair Value		Carrying Amount		Fair Value

(1)Included in other assets on the condensed consolidated balance sheets.

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

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

(4)The carrying amount of the debt instrument is presented net of debt issuance costs, premium and discount. Refer to Note 9, “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).

Interest rate swaps were measured at fair value using quoted market prices for the swap interest rate indexes over the term of the swap discounted to present value versus the fixed rate of the contract. The interest rate caps were measured at fair value using implied volatility rates of each individual caplet and the yield curve for the related periods.

The Company’s derivative contracts consist of foreign currency exchange contracts and interest rate swap and cap agreements. These derivative contracts are over-the-counter, and their fair value is determined using modeling techniques that include market inputs such as interest rates, yield curves, and currency exchange rates. These contracts are categorized as Level 2 in the fair value hierarchy.

The estimated fair value of the Company’s term loans was based on information provided by the agent under the Company’s senior secured credit facility. The estimated fair values of the Company’s notes were based upon quoted market prices. 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 significant impact to the fair value of derivative assets based on the Company's evaluation of counterparties' credit risks.

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 January 1, 2022 and September 30, 2021.

12.    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 and cap counterparties that contain a provision whereby if the Company defaults on the credit facility the Company could also be declared in default on its swaps and caps, resulting in an acceleration of payment under the swaps and caps.

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 and Cap Agreements – Interest rate swap and cap agreements are used to manage interest rate risk associated with floating-rate borrowings under our credit facility. The interest rate swap and cap 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 through the expiration date of the interest rate swap and cap agreements, thereby reducing the impact of interest rate changes on future interest expense. 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. These derivative instruments qualify as effective cash flow hedges under U.S. GAAP. For these cash flow hedges, the effective portion of the gain or loss from the financial instruments was 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 affected earnings. As the interest rate swap and cap 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.

The following table summarizes the Company's interest rate swap agreements:

Aggregate Notional Amount (in millions)	Start Date	End Date	Related Term Loans	Conversion of Related Variable Rate Debt to Fixed Rate of:
$500	6/29/2018	3/31/2025	Tranche E	5.25% (3.0% plus the 2.25% margin percentage)
$750	6/30/2020	6/30/2022	Tranche E	4.75% (2.5% plus the 2.25% margin percentage)
$1,500	6/30/2022	3/31/2025	Tranche E	5.35% (3.1% plus the 2.25% margin percentage)
$700	3/31/2023	9/30/2025	Tranche F	3.55% (1.3% plus the 2.25% margin percentage)
$1,400	6/30/2021	3/31/2023	Tranche F	5.25% (3.0% plus the 2.25% margin percentage)
$400	9/30/2017	9/30/2022	Tranche G	4.15% (1.9% plus the 2.25% margin percentage)
$900	12/31/2021	6/28/2024	Tranche G	5.35% (3.1% plus the 2.25% margin percentage)
$400	9/30/2022	6/28/2024	Tranche G	5.25% (3.0% plus the 2.25% margin percentage)

The following table summarizes the Company's interest rate cap agreements:

Aggregate Notional Amount (in millions)	Start Date	End Date	Related Term Loans	Offsets Variable Rate Debt Attributable to Fluctuations Above:
$750	6/30/2020	6/30/2022	Tranche E	Three month LIBOR rate of 2.50%
$700	3/31/2023	9/30/2025	Tranche F	Three month LIBOR rate of 1.25%

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):

	January 1, 2022				September 30, 2021
	Asset		Liability		Asset		Liability
Interest rate cap agreements	$	11	$	—	$	8	$	—
Interest rate swap agreements	—		(209)		—		(280)
Net derivatives as classified in the condensed consolidated balance sheets (1)	$	11	$	(209)	$	8	$	(280)

(1)Refer to Note 11, “Fair Value Measurements,” for the condensed consolidated balance sheets classification of our interest rate swap and cap agreements.

Based on the fair value amounts of the interest rate swap and cap agreements determined as of January 1, 2022, the estimated net amount of existing gains and losses and caplet amortization expected to be reclassified into interest expense-net within the next 12 months is approximately $106.3 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 January 1, 2022, the Company had outstanding foreign currency forward exchange contracts to sell U.S. dollars with notional amounts of $97.5 million. The maximum duration of the Company’s foreign currency cash flow hedge contracts at January 1, 2022 is 9 months. These notional values consist of contracts for the Canadian dollar and the European 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 January 1, 2022, the losses reclassified on settlements of foreign currency forward exchange contracts designated as cash flow hedges into net sales were less than $1 million. The losses were previously recorded as a component of accumulated other comprehensive loss in stockholders' deficit.

As of January 1, 2022, the Company expects to record a net loss of approximately $3.7 million on foreign currency forward exchange contracts designated as cash flow hedges to net sales over the next 12 months.

13.    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/electro-mechanical 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.

17

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 and parachutes. 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/electro-mechanical 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 plans, restructuring costs related to the Company's cost reduction measures in response to the COVID-19 pandemic, foreign currency gains and losses, acquisition-integration costs, acquisition and divestiture transaction-related expenses, and refinancing costs. COVID-19 pandemic restructuring costs represent actions taken by the Company to reduce its workforce to align with customer demand, as well as incremental costs related to the pandemic that are not expected to recur once the pandemic has subsided and are clearly separable from normal operations (e.g., additional cleaning and disinfecting of facilities by contractors above and beyond normal requirements, personal protective equipment). 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 condensed 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 office 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 are allocated to the operating segments.

Net periodic pension benefit (income) cost for the Company’s U.S. and non-U.S. post-retirement pension plans was less than $1 million for the thirteen week periods ended January 1, 2022 and January 2, 2021, respectively. The components of net periodic pension benefit cost, other than service cost, are included in other income in the condensed consolidated statements of income.

Effective June 30, 2021, the Company terminated the Esterline Technologies Retirement Plan (the “ERP”) in accordance with IRS regulations. Pension obligations will be distributed through a combination of lump sum payments to eligible plan participants and the purchase of a group annuity contract. Upon settlement of the pension obligations, the Company will reclassify unrecognized actuarial gains or losses, currently recorded as a component of accumulated other comprehensive loss in stockholders' deficit, to the Company's condensed consolidated statements of income as settlement gains or charges. The Company anticipates the termination process will be completed by the end of fiscal year 2022.

16.    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 12 months or less. Additionally, when accounting for leases, the Company combines payments for leased assets, related services and other components of a lease.

The components of lease expense are as follows (in millions):

		Thirteen Week Periods Ended
	Classification	January 1, 2022		January 2, 2021

17.    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 $20.8 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 that were too high.

No loss contingency related to the voluntary refund request has been recorded as of January 1, 2022 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 Exchange Act, and 27A of the Securities Act. 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 those described under “Risk Factors” in the 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 impact that the COVID-19 pandemic has on our business, results of operations, financial condition and liquidity; 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; future geopolitical or other worldwide events; cyber-security threats and natural disasters; our reliance on certain customers; the U.S. defense budget and risks associated with being a government supplier including government audits and investigations; failure to maintain government or industry approvals; failure to complete or successfully integrate acquisitions; our indebtedness; potential environmental liabilities; liabilities arising in connection with litigation; increases in raw material costs, taxes and labor costs that cannot be recovered in product pricing; 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. 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/electro-mechanical 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, and cargo loading, handling and delivery systems. Each of these 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 2022, we generated net sales of $1,194 million and net income attributable to TD Group of $163 million. EBITDA As Defined was $565 million, or 47.3% 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 continuing operations and net cash provided by operating activities.

The COVID-19 pandemic is continuing to cause an adverse impact on our employees, operations, supply chain and distribution system and the long-term impact to our business remains unknown. This is due to the numerous uncertainties that have risen from the pandemic, including the severity of the disease, the duration of the outbreak, the likelihood of resurgences of the outbreak, including due to the emergence and spread of variants, actions that may be taken by governmental authorities in response to the disease including vaccination mandates, the continued efficacy and public acceptance of vaccines, and unintended consequences of the foregoing.

The commercial aerospace industry, in particular, has been significantly disrupted, both domestically and internationally, by the pandemic. The pandemic has resulted in governments around the world implementing stringent measures to help control the spread of the virus, including quarantines, “shelter in place” and “stay at home” orders, travel restrictions, business curtailments and other measures. As a result, demand for travel declined at a rapid pace beginning in the second half of fiscal 2020 and has remained depressed compared to pre-pandemic levels. However, commercial air travel has increasingly shown signs of recovery in recent months with increasing air traffic, primarily in certain domestic markets. The recovery in international commercial air travel has been slower with international travel only slightly recovered from COVID-19 pandemic lows. The exact pace and timing of the commercial air travel recovery remains uncertain and is expected to continue to be uneven depending on factors such as trends in the number of COVID-19 infections (e.g., impact of new variants of COVID-19 resurfacing), the continued efficacy and public acceptance of vaccines and easing of quarantines and travel restrictions, among other factors.

The COVID-19 pandemic has also disrupted the global supply chain to a certain extent and availability of raw materials, particularly electronic parts. Because we strive to limit the volume of raw materials and component parts on hand, our business could be adversely affected if we were unable to obtain these 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 FAA and OEM certification processes associated with aerospace products could prevent efficient replacement of a supplier, raw material or component part.

We currently expect COVID-19 to continue to cause an adverse impact on our net sales, net income and EBITDA as Defined compared to pre-pandemic levels into fiscal 2022. Longer-term, because the duration of the pandemic is unclear, it is difficult to forecast a precise impact on the Company’s future results. We will continue to evaluate the nature and extent to which COVID-19 will impact our business, supply chain, consolidated results of operations, financial condition, and liquidity.

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.

Changes in Results of Operations

Thirteen week period ended January 1, 2022 compared with the thirteen week period ended January 2, 2021

Total Company

•Net Sales. Net organic sales and acquisition and divestiture sales and the related dollar and percentage changes for the thirteen week periods ended January 1, 2022 and January 2, 2021 were as follows (amounts in millions):

	Thirteen Week Periods Ended						% Change Net Sales
	January 1, 2022		January 2, 2021		Change
Organic sales	$	1,153	$	1,057	$	96	8.7	%
Acquisition and divestiture sales	41		51		(10)		(0.9)	%
Net sales	$	1,194	$	1,108	$	86	7.8	%

Organic sales represent net sales from existing businesses owned by the Company, excluding sales from acquisitions and divestitures. Acquisition sales represent net sales from acquired businesses for the period up to one year subsequent to their respective acquisition date. Divestiture sales represent net sales from businesses up to the date the respective divestiture was completed. Acquisition and divestiture sales are excluded from organic sales due to the variability in the nature, timing and extent of acquisitions and divestitures and resulting variable impact on underlying trends. No acquisitions or divestitures occurred in the first quarter of fiscal 2022. Therefore, the acquisition and divestiture sales presented above relate to acquisitions and divestitures completed in fiscal 2021. Refer to Note 3, “Acquisitions and Divestitures,” in the notes to the condensed consolidated financial statements included herein for further information on the Company's acquisition and divestiture activity.

The increase in organic sales of $96 million for the thirteen week period ended January 1, 2022 compared to the thirteen week period ended January 2, 2021, is primarily related to increases in commercial aftermarket sales ($112 million, an increase of 49.7%) and commercial OEM sales ($28 million, an increase of 12.5%); partially offset by decreases in OEM and aftermarket defense sales ($46 million, a decrease of 8.6%). The increase in commercial aftermarket sales is primarily attributable to the continued recovery in commercial air travel demand, particularly the increase in the utilization of narrow-body aircraft, and air cargo demand and the resulting higher flight hours in the first quarter of fiscal 2022 compared to the first quarter of fiscal 2021. The increase in OEM sales is primarily attributable to a higher volume of narrow-body aircraft deliveries by aircraft manufacturers to airlines and also expected production rate increases of narrow-body aircraft compared to the first quarter of fiscal 2021. Partially offsetting the OEM sales growth are wide-body aircraft production and delivery slowdowns due to the COVID-19 pandemic adversely impacting international travel and also due to Boeing's quality control issues with the 787 aircraft. The decrease in defense sales (for both OEM and aftermarket) is primarily attributable to supply chain-induced delays in fulfilling orders at certain operating units.

The decrease in acquisition and divestiture sales for the thirteen week period ended January 1, 2022 is primarily attributable to the divestitures of ScioTeq and TREALITY Simulation Visual Systems (“ScioTeq and TREALITY”), Technical Airborne Components (“TAC”), Racal Acoustics (“Racal”) and Avista, Inc. (“Avista”), all of which were completed in fiscal 2021; partially offset by the acquisition of Cobham Aero Connectivity (“CAC”), which was completed in the second quarter of fiscal 2021.

•Cost of Sales and Gross Profit. Cost of sales decreased by $34 million, or 6.0%, to $533 million for the thirteen week period ended January 1, 2022 compared to $567 million for the thirteen week period ended January 2, 2021. Cost of sales and the related percentage of net sales for the thirteen week periods ended January 1, 2022 and January 2, 2021 were as follows (amounts in millions):

	Thirteen Week Periods Ended
	January 1, 2022			January 2, 2021			Change		% Change
Cost of sales - excluding costs below	$	542		$	545		$	(3)	(0.6)	%
% of net sales	45.4		%	49.2		%
Non-cash stock compensation expense	4			5			(1)		(20.0)	%
% of net sales	0.3		%	0.5		%
COVID-19 pandemic restructuring costs	—			13			(13)		(100.0)	%
% of net sales	—		%	1.2		%
Foreign currency (gains) losses	(1)			22			(23)		(104.5)	%
% of net sales	(0.1)		%	2.0		%
Loss contract amortization	(12)			(18)			6		33.3	%
% of net sales	(1.0)		%	(1.6)		%
Total cost of sales	$	533		$	567		$	(34)	(6.0)	%
% of net sales	44.6		%	51.2		%
Gross profit	$	661		$	541		$	120	22.2	%
Gross profit percentage	55.4		%	48.8		%

In addition to the other factors summarized above, the decrease in the dollar amount of cost of sales during the thirteen week period ended January 1, 2022 was primarily driven by a favorable sales mix, specifically, higher commercial aftermarket sales as a percentage of net sales compared to commercial OEM net sales in the comparable period one year ago. COVID-19 pandemic restructuring costs were not material in the first quarter of fiscal 2022 and foreign exchange rates, particularly the United States dollar compared to the British pound and the Euro, were significantly less volatile compared to the first quarter of fiscal 2021 when the U.S. dollar depreciated against both the British pound and Euro resulting in foreign currency losses.

In addition, the continued application of our three core value-driven operating strategies (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, resulted in gross profit as a percentage of net sales increasing by 6.6 percentage points to 55.4% for the thirteen week period ended January 1, 2022 from 48.8% for the thirteen week period ended January 2, 2021.

•Selling and Administrative Expenses. Selling and administrative expenses decreased by $27 million to $170 million, or 14.2% of net sales, for the thirteen week period ended January 1, 2022 from $197 million, or 17.8% of net sales, for the thirteen week period ended January 2, 2021. Selling and administrative expenses and the related percentage of net sales for the thirteen week periods ended January 1, 2022 and January 2, 2021 were as follows (amounts in millions):

	Thirteen Week Periods Ended
	January 1, 2022			January 2, 2021			Change		% Change
Selling and administrative expenses - excluding costs below	$	133		$	138		$	(5)	(3.6)	%
% of net sales	11.1		%	12.5		%
Non-cash stock compensation expense	33			44			(11)		(25.0)	%
% of net sales	2.8		%	4.0		%
Acquisition integration costs	3			1			2		200.0	%
% of net sales	0.3		%	0.1		%
Acquisition and divestiture transaction-related expenses	1			2			(1)		(50.0)	%
% of net sales	0.1		%	0.2		%
Bad debt expense	—			5			(5)		(100.0)	%
% of net sales	—		%	0.5		%
COVID-19 pandemic restructuring costs	—			7			(7)		(100.0)	%

Total selling and administrative expenses	$	170		$	197		$	(27)	(13.7)	%
% of net sales	14.2		%	17.8		%

The decrease in selling and administrative expenses during the thirteen week period ended January 1, 2022 is primarily due to the realization of the cost mitigation measures previously enacted in response to the COVID-19 pandemic as well as the other factors summarized above. The decrease in non-cash stock compensation expense is attributable to the impact on expense in the first quarter of fiscal 2021 from the Black-Scholes fair value on certain fiscal 2021 and fiscal 2020 stock option grant modifications in connection with the change in vesting terms approved by the Compensation Committee of the Board of Directors. COVID-19 pandemic restructuring costs and bad debt expense was not material in the first quarter of fiscal 2022 as the commercial aerospace market continues to recover particularly when compared to the first quarter of fiscal 2021.

•Amortization of Intangible Assets. Amortization of intangible assets was $36 million for the thirteen week period ended January 1, 2022 compared to $29 million for the thirteen week period ended January 2, 2021. The increase in amortization expense of $7 million was due to the amortization expense recognized on intangible assets from the acquisition of CAC.

•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 and interest on finance leases; slightly offset by interest income. Interest expense-net decreased $3 million, or 1.1%, to $264 million for the thirteen week period ended January 1, 2022 from $267 million for the comparable thirteen week period in the prior fiscal year. The decrease in interest expense-net was primarily due to refinancing activities completed in fiscal 2021 lowering the interest rate on certain senior subordinated notes and also a decrease in the weighted average level of outstanding borrowings, which was approximately $19.8 billion for the thirteen week period ended January 1, 2022 and approximately $19.9 billion for the thirteen week period ended January 2, 2021. The decrease in the weighted average level of borrowings was primarily due to the repayment of $200 million previously drawn on the revolving credit facility. The weighted average interest rate for cash interest payments on total borrowings outstanding for the thirteen week period ended January 1, 2022 was 5.1%.

•Other Income. Other income was $2 million for the thirteen week period ended January 1, 2022 compared to $5 million recorded for the thirteen week period ended January 2, 2021. Other income for the thirteen week period ended January 1, 2022 is primarily driven by the non-service related components of net periodic benefit costs on the Company's defined benefit pension plans ($1 million). Other income for the thirteen week period ended January 2, 2021 is primarily driven by the release of a litigation reserve ($3 million) and the non-service related components of net periodic benefit costs on the Company's defined benefit pension plans ($2 million).

29

•Income Taxes. Income tax expense as a percentage of income before income taxes was approximately 15.7% for the thirteen week period ended January 1, 2022 compared to 5.5% for the thirteen week period ended January 2, 2021. The Company's higher effective tax rate for the thirteen week period ended January 1, 2022 was primarily due to the ratio of the discrete impact of excess tax benefits from share-based payments to income from continuing operations being lower in the thirteen week period ended January 1, 2022 resulting from an increase in income from continuing operations before income taxes for the same thirteen week period. The Company’s effective income tax rate of 15.7% for the thirteen week period ended January 1, 2022 was lower than the federal statutory tax rate of 21.0%, primarily due to the discrete impact of excess tax benefits associated with share-based payments during the first quarter of fiscal 2022.

•Income from Discontinued Operations, net of tax. Income from discontinued operations, net of tax, for the thirteen week period ended January 1, 2022 was $1 million, which was driven by a final working capital settlement received related to the divestiture of the Souriau-Sunbank Connection Technologies business (“Souriau-Sunbank”) to Eaton Corporation plc (“Eaton”) during the first quarter of fiscal 2022. Refer to Note 3, “Acquisitions and Divestitures,” in the notes to the condensed consolidated financial statements included herein for further information.

•Net Income Attributable to TD Group. Net income attributable to TD Group increased $113 million, to $163 million for the thirteen week period ended January 1, 2022 compared to net income attributable to TD Group of $50 million for the thirteen week period ended January 2, 2021.

•Earnings (Loss) per Share. Basic and diluted earnings (loss) per share was $1.98 for the thirteen week period ended January 1, 2022 and $(0.42) per share for the thirteen week period ended January 2, 2021. Basic and diluted earnings per share from discontinued operations was $0.02 for the thirteen week period ended January 1, 2022. There was no impact on earnings per share from discontinued operations for the thirteen week period ended January 2, 2021.

Business Segments

•Segment Net Sales. Net sales by segment for the thirteen week periods ended January 1, 2022 and January 2, 2021 were as follows (amounts in millions):

	Thirteen Week Periods Ended
	January 1, 2022		% of Net Sales		January 2, 2021		% of Net Sales		Change		% Change
Power & Control	$	650	54.4	%	$	601	54.2	%	$	49	8.2	%
Airframe	506		42.4	%	464		41.9	%	42		9.1	%
Non-aviation	38		3.2	%	43		3.9	%	(5)		(11.6)	%
Net sales	$	1,194	100.0	%	$	1,108	100.0	%	$	86	7.8	%

Net sales for the Power & Control segment increased $49 million, an increase of 8.2%, for the thirteen week period ended January 1, 2022 compared to the thirteen week period ended January 2, 2021. The sales increase resulted primarily from increases in organic sales in the commercial aftermarket ($58 million, an increase of 46.8%) and commercial OEM ($20 million, an increase of 19.1%); partially offset by decreases in organic OEM and aftermarket defense sales ($30 million, a decrease of 8.8%). The increase in commercial aftermarket sales is primarily attributable to the continued recovery in commercial air travel demand, particularly the increase in the utilization of narrow-body aircraft, and air cargo demand and the resulting higher flight hours in the first quarter of fiscal 2022 compared to the first quarter of fiscal 2021. The increase in OEM sales is primarily attributable to a higher volume of narrow-body aircraft deliveries by aircraft manufacturers to airlines and also expected production rate increases of narrow-body aircraft compared to the first quarter of fiscal 2021. Partially offsetting the OEM sales growth are wide-body aircraft production and delivery slowdowns due to the COVID-19 pandemic adversely impacting international travel and also due to Boeing's quality control issues with the 787 aircraft. The decrease in defense sales (for both OEM and aftermarket) is primarily attributable to supply chain-induced delays in fulfilling orders at certain operating units. The change in acquisition and divestiture sales was not material for the thirteen week period ended January 1, 2022.

30

Net sales for the Airframe segment increased $42 million, an increase of 9.1%, for the thirteen week period ended January 1, 2022 compared to the thirteen week period ended January 2, 2021. The sales increase resulted primarily from increases in organic sales in the commercial aftermarket ($54 million, an increase of 53.2%) and commercial OEM sales ($9 million, an increase of 7.4%); partially offset by decreases in organic OEM and aftermarket defense sales ($15 million, a decrease of 7.9%). The increase in commercial aftermarket sales is primarily attributable to the continued recovery in commercial air travel demand, particularly the increase in the utilization of narrow-body aircraft, and air cargo demand and the resulting higher flight hours in the first quarter of fiscal 2022 compared to the first quarter of fiscal 2021. The increase in OEM sales is primarily attributable to a higher volume of narrow-body aircraft deliveries by aircraft manufacturers to airlines and also expected production rate increases of narrow-body aircraft compared to the first quarter of fiscal 2021. Partially offsetting the OEM sales growth are wide-body aircraft production and delivery slowdowns due to the COVID-19 pandemic adversely impacting international travel and also due to Boeing's quality control issues with the 787 aircraft. The decrease in defense sales (for both OEM and aftermarket) is primarily attributable to supply chain-induced delays in fulfilling orders at certain operating units. Acquisition and divestiture sales decreased by $5 million for the thirteen week period ended January 1, 2022 due to the impact on the comparable period from the divestitures completed in fiscal 2021.

Net sales for the Non-aviation segment decreased $5 million, a decrease of 11.6%, for the thirteen week period ended January 1, 2022 compared to the thirteen week period ended January 2, 2021. The sales decrease is due to the impact on the comparable period ($4 million) from the divestitures completed in fiscal year 2021.

•EBITDA As Defined. Refer to “Non-GAAP Financial Measures” in this discussion and analysis for further information on EBITDA as Defined. EBITDA As Defined by segment for the thirteen week periods ended January 1, 2022 and January 2, 2021 were as follows (amounts in millions):

	Thirteen Week Periods Ended
	January 1, 2022		% of  Segment Net Sales		January 2, 2021		% of  Segment Net Sales		Change		% Change
Power & Control	$	328	50.5	%	$	304	50.6	%	$	24	7.9	%
Airframe	226		44.7	%	177		38.1	%	49		27.7	%
Non-aviation	14		36.8	%	15		34.9	%	(1)		(6.7)	%
	$	568	47.6	%	$	496	44.8	%	$	72	14.5	%

Organic EBITDA As Defined represents EBITDA As Defined from existing businesses owned by the Company as of January 1, 2022, excluding EBITDA As Defined from acquisitions and divestitures. EBITDA As Defined from acquisitions and divestitures represents EBITDA As Defined from acquired businesses for the period up to one year subsequent to the respective acquisition date and from businesses up to the date the respective divestiture was completed. No acquisitions or divestitures occurred in the first quarter of fiscal 2022. The EBITDA as Defined from acquisition and divestitures relate to acquisitions and divestitures completed in fiscal 2021.

EBITDA As Defined for the Power & Control segment increased approximately $24 million, an increase of 7.9%, resulting from higher organic sales, particularly in the commercial aftermarket and OEM channels. Also contributing to the increase in EBITDA as Defined was the application of our three core value-driven operating strategies and positive leverage on our fixed overhead costs spread over a higher production volume. The change in EBITDA As Defined for the Power & Control segment from acquisitions and divestitures was immaterial for the thirteen week period ended January 1, 2022.

EBITDA As Defined for the Airframe segment increased approximately $49 million, an increase of 27.7%, resulting primarily from higher organic sales, particularly in the commercial aftermarket and OEM channels. Also contributing to the increase in EBITDA as Defined was the application of our three core value-driven operating strategies and positive leverage on our fixed overhead costs spread over a higher production volume. EBITDA As Defined for the Airframe segment from acquisitions and divestitures increased by $1 million, primarily due to the impact on the comparable period from the divestitures completed in fiscal year 2021.

EBITDA As Defined for the Non-aviation segment decreased approximately $1 million, a decrease of 6.7%, due to the impact on the comparable period ($2 million) from the divestitures completed in fiscal year 2021.

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.

The following tables present selected balance sheet, cash flow and other financial data relevant to the liquidity or capital resources of the Company for the periods specified below (amounts in millions):

	January 1, 2022		September 30, 2021
Selected Balance Sheet Data:
Cash and cash equivalents	$	4,813	$	4,787
Working capital	5,593		5,367
Total assets	19,242		19,315
Total debt (1)	19,814		19,998
TD Group stockholders’ deficit	(2,633)		(2,916)

(1)Includes debt issuance costs and original issue discount and premiums. Reference Note 9, “Debt,” in the notes to the condensed consolidated financial statements included herein for additional information.

Capital expenditures	25		31
Ratio of earnings to fixed charges (1)	1.7x		1.2x

(1)For purposes of computing the ratio of earnings to fixed charges, earnings consist of earnings from continuing operations before income taxes plus fixed charges. Fixed charges consist of interest expense, amortization of debt issuance costs, original issue discount and premium and the “interest component” of rental expense.

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. Whether the Company undertakes common stock repurchases or other aforementioned activities will depend on prevailing market conditions, the Company's liquidity requirements, contractual restrictions and other factors. The amounts involved may be material. In addition, the Company may issue additional debt if prevailing market conditions are favorable to doing so.

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, including the ongoing COVID-19 pandemic.

The Company is continuing to strategically manage the Company’s cash and cash equivalents in response to the ongoing COVID-19 pandemic and related uncertainty of the duration and impact of the pandemic on the Company’s business in fiscal 2022 and beyond. In the first quarter of fiscal 2022, the Company entered into Amendment No. 9 and Incremental Revolving Credit Assumption Agreement (herein, “Amendment No. 9”) to the Second Amended and Restated Credit Agreement dated as of June 4, 2014 (the "Credit Agreement"), increasing the capacity under the revolving credit facility from $760 million to $810 million. The Company also repaid $200 million previously drawn on the revolving credit facility. In fiscal 2021, due to favorable market conditions in the high yield bond market, the Company refinanced $1,950 million of its senior subordinated notes resulting in a reduced interest rate (estimated $35 million reduction in annual interest payments) and an extended maturity date.

32

As of January 1, 2022, the Company has significant cash liquidity as illustrated in the table presented below (in millions):

	As of January 1, 2022
Cash and cash equivalents	$	4,813
Availability on revolving credit facility (1)	777
Cash liquidity	$	5,590

(1)On December 29, 2021, the Company entered into Amendment No. 9 and Incremental Revolving Credit Assumption Agreement to the Second Amended and Restated Credit Agreement dated as of June 4, 2014, which increased the capacity under the revolving credit facility from $760 million to $810 million.

We believe our significant cash liquidity will allow us to meet our anticipated funding requirements. 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 August 2024.

In connection with the continued application of our three core value-driven operating strategies (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 in consideration of the ongoing COVID-19 pandemic.

In the future, 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 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 $279 million of net cash from operating activities during the thirteen week period ended January 1, 2022 compared to $274 million during the thirteen week period ended January 2, 2021.

The change in accounts receivable during the thirteen week period ended January 1, 2022 was a source of cash of $117 million compared to a source of cash of $86 million during the thirteen week period ended January 2, 2021. The increase in the source of cash of $31 million is primarily attributable to the higher amount of sales in the fourth quarter of fiscal 2021 compared to fiscal 2020 and the subsequent timing of payments received by customers in the first quarter. The Company continues to actively manage its accounts receivable, the related agings and collection efforts in response to the COVID-19 pandemic.

The change in inventories during the thirteen week period ended January 1, 2022 was a use of cash of $32 million compared to a source of cash of $1 million during the thirteen week period ended January 2, 2021. The increase in the use of cash is primarily driven by increased purchasing from higher demand and also due to the typical lower production levels in the second half of December due to the holidays. The Company continues to actively manage inventory levels in response to the pandemic and its adverse impact on the supply chain.

The change in accounts payable during the thirteen week period ended January 1, 2022 was a use of cash of $14 million compared to a use of cash of $20 million during the thirteen week period ended January 2, 2021 due to the timing of payments to suppliers.

Investing Activities. Net cash used in investing activities was $25 million during the thirteen week period ended January 1, 2022, consisting of capital expenditures of $25 million.

Net cash used in investing activities was $29 million during the thirteen week period ended January 2, 2021, consisting primarily of capital expenditures of $31 million. This was partially offset by proceeds of $8 million from the completion of the divestiture of Avista.

Financing Activities. Net cash used in financing activities during the thirteen week period ended January 1, 2022 was $225 million. The use of cash was primarily attributable to a $200 million repayment of a previous draw on the revolving credit facility, dividend equivalent payments of $46 million and repayment on term loans of $19 million. This was partially offset by $40 million in proceeds from stock option exercises.

33

Net cash used in financing activities during the thirteen week period ended January 2, 2021 was $60 million. The use of cash was primarily attributable to dividend equivalent payments of $73 million and repayments on term loans of $19 million. This was partially offset by $32 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. There were no material changes during the thirteen week period ended January 1, 2022 to these obligations as reported in our Annual Report on Form 10-K for the fiscal year ended September 30, 2021 other than the repayment of $200 million previously drawn on the revolving credit facility.

Description of Senior Secured Term Loans and Indentures

Senior Secured Term Loans Facility

TransDigm has $7,354 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 January 1, 2022):

Term Loans Facility	Aggregate Principal	Maturity Date	Interest Rate
Tranche E	$2,171 million	May 30, 2025	LIBOR + 2.25%
Tranche F	$3,445 million	December 9, 2025	LIBOR + 2.25%
Tranche G	$1,738 million	August 22, 2024	LIBOR + 2.25%

The Term Loans Facility requires quarterly aggregate principal payments of $18.8 million. The revolving commitments consist of two tranches which include up to $151.5 million of multicurrency revolving commitments. At January 1, 2022, the Company had $33.5 million in letters of credit outstanding and $776.5 million in borrowings available under the revolving commitments.

The interest rates per annum applicable to the loans under the Credit Agreement are, at TransDigm’s option, equal to either an alternate base rate or an adjusted LIBOR for one, two, three or six-month (or to the extent agreed to by each relevant lender, nine or twelve-month) interest periods chosen by TransDigm, in each case plus an applicable margin percentage. The adjusted LIBOR related to tranche E, tranche F and tranche G term loans are not subject to a floor. For the thirteen week period ended January 1, 2022, the applicable interest rate was approximately 2.34% on the existing term loans. Interest rate swaps and caps used to hedge and offset, respectively, the variable interest rates on the credit facility are described in Note 12, “Derivatives and Hedging Activities,” in the notes to the condensed consolidated financial statements included herein.

Fiscal 2022 Amendment to the Credit Agreement

On December 29, 2021, the Company entered into Amendment No. 9 and Incremental Revolving Credit Assumption Agreement (herein, “Amendment No. 9”) to the Credit Agreement, which increases the capacity under the revolving credit facility from $760 million to $810 million. The terms and conditions that apply to Amendment No. 9 are the same as the terms and conditions that apply to the existing dollar revolving commitments and term loans under the Credit Agreement.

Certain Restrictive Covenants in Our Debt Documents

The Credit Agreement and the Indentures governing the 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. 7.

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 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 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 $283.5 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 January 1, 2022, 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 Receivables 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.

On July 27, 2021, the Company amended the Securitization Facility to, among other things, (i) extend the maturity date to July 26, 2022, and (ii) bear interest at a rate of 1.20% plus three month LIBOR, compared to the interest rate of 1.35% plus 0.50% or three month LIBOR, whichever is greater, that applied prior to the amendment. The Securitization Facility is collateralized by substantially all of the Company’s domestic operations’ trade accounts receivable. As of January 1, 2022, the Company has borrowed $350 million under the Securitization Facility, which is fully drawn.

36

Dividend and Dividend Equivalent Payments

No dividends were declared or paid in the first quarter of fiscal 2022. We do not anticipate declaring regular quarterly or annual cash dividends on our common stock in the near future. Any declaration of special cash dividends on our common stock in the future 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 senior secured credit facility and Indentures, 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 senior secured credit facility and Indentures and may be limited by future debt or other agreements that we may enter into.

Dividend equivalent payments made in fiscal 2022 were $46 million. Pursuant to the Third Amended and Restated TransDigm Group Incorporated 2003 Stock Option Plan Dividend Equivalent Plan, the Second Amended and Restated TransDigm Group Incorporated 2006 Stock Incentive Plan Dividend Equivalent Plan and the 2014 Stock Option Plan Dividend Equivalent Plan, all of the options granted under the existing stock option plans are entitled to certain dividend equivalent payments in the event of the declaration of a dividend by the Company.

Stock Repurchase Program

On November 8, 2017, our Board of Directors, authorized a stock repurchase program permitting repurchases of our outstanding shares not to exceed $650 million in the aggregate, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes.

No repurchases were made under the program during the fiscal quarter ended January 1, 2022. As of January 1, 2022, the remaining amount of repurchases allowable under the $650 million program was $631.1 million subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes.

On January 27, 2022, our Board of Directors authorized a new stock repurchase program permitting repurchases of our outstanding shares not to exceed $2,200 million in the aggregate, replacing the $650 million stock repurchase program, subject to any restrictions specified in the Credit Agreement and/or Indentures governing the existing Notes.

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 January 1, 2022, the Company had $33.5 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 income from continuing operations 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.

Management's Discussion and Analysis of Financial Condition and Results of Operations. Market risks are described more fully within Quantitative and Qualitative Disclosures About Market Risk in Part II, Item 7A of our most recent Form 10-K (for the fiscal year ended September 30, 2021, filed on November 16, 2021). These market risks have not materially changed for the first quarter of fiscal 2022.

ITEM 4. CONTROLS AND PROCEDURES

As of January 1, 2022, 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. In designing and evaluating the disclosure controls and procedures, TD Group’s management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures.

Changes in 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 17, “Commitments and Contingencies,” to the condensed consolidated financial statements 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, 2021, filed on November 16, 2021.

ACQUISITIONS AND DIVESTITURES

ACQUISITIONS AND DIVESTITURES

Acquisitions

Cobham Aero Connectivity – On November 24, 2020, the Company entered into a definitive agreement to acquire all the outstanding stock of Chelton Limited, Chelton Avionics Holdings, Inc. and Mastsystem Int'l Oy, collectively, Cobham Aero Connectivity (“CAC”), for a total purchase price of $945 million. The acquisition was substantially completed on January 5, 2021 and financed through existing cash on hand. The Company completed the remainder of the acquisition of CAC on February 12, 2021, also through existing cash on hand. CAC operates from two primary facilities (Marlow, United Kingdom and Prescott, Arizona) and is a leading provider of highly engineered antennas and radios for the aerospace end market. The products are primarily proprietary with significant aftermarket content and have a strong presence across major defense platforms as well as select commercial applications. CAC's operating results are included within TransDigm's Airframe segment.

The acquisition strengthens and expands 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 strategies (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers). The purchase price paid for the acquisition reflects the current earnings before interest, taxes, depreciation and amortization (“EBITDA”) and cash flows, as well as the future EBITDA and cash flows expected to be generated by the business, 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.

The Company accounted for the CAC acquisition using the acquisition method of accounting and third-party valuation appraisals and included the results of operations of the acquisition in its condensed consolidated financial statements from the effective dates of the acquisition. The total purchase price of CAC was allocated to the underlying assets acquired and liabilities assumed based upon the respective fair value at the dates of acquisition. To the extent the purchase price exceeded the fair value of the net identifiable tangible and intangible assets acquired, such excess was allocated to goodwill. The fair values of acquired intangibles and certain liabilities, such as loss contract reserves, are determined based on estimates and assumptions that are deemed reasonable by the Company. Significant assumptions used to determine the fair values of acquired intangible assets include the discount rates and certain assumptions that form the basis of the forecasted results of the acquired business including revenue growth rates, EBITDA margins, royalty rates and technology obsolescence rates. Significant assumptions used to determine the fair value of the loss contract reserves using the discounted cash flow model include discount rates and forecasted costs to be incurred under the long-term contracts and at-market bid prices for respective contracts. These assumptions are forward looking and could be affected by future economic and market conditions.

Pro forma net sales and results of operations for the acquisition had it occurred at the beginning of the applicable thirteen week period ended January 1, 2022 or January 2, 2021 are not material and, accordingly, are not provided.

The final allocation of the fair value of assets acquired and liabilities assumed in the CAC acquisition as of the acquisition date, as well as measurement period adjustments recorded as of January 1, 2022, are summarized in the table below (in millions):

	Preliminary Allocation		Measurement Period Adjustments			Final Allocation
Assets acquired (excluding cash):
Trade accounts receivable	$	31	$	1		$	32
Inventories	27		2			29
Prepaid expenses and other	10		(3)			7
Property, plant and equipment	18		3			21
Goodwill	636		61			697		(1)
Other intangible assets	309		15			324		(1)
Other	34		(3)			31
Total assets acquired (excluding cash)	1,065		76			1,141
Liabilities assumed:
Accounts payable	15		3			18
Accrued and other current liabilities	38		6		(2)	44
Deferred income taxes	38		(7)			31
Other non-current liabilities	29		74		(2)	103
Total liabilities assumed	120		76			196
Net assets acquired	$	945	$	—		$	945

(1)Of the approximately $697 million of goodwill recognized for the acquisition, approximately $65 million is deductible for tax purposes. Of the approximately $324 million of other intangible assets recognized for the acquisition, approximately $105 million is deductible for tax purposes. The goodwill and intangible assets are deductible over 15 years.

(2)Primarily relates to the recording of loss contract reserves associated with acquired ongoing long-term contracts with customers that were incurring negative gross margins as of the date of acquisition. Based on our review of these contracts, we concluded that the terms of certain contracts were unfavorable when compared to market terms as of the acquisition date. The loss contract reserves, totaling $80.6 million, will be released over an estimated three to five year period.

Divestitures

ScioTeq and TREALITY Simulation Visual Systems – On June 30, 2021, TransDigm completed the divestiture of its ScioTeq and TREALITY Simulation Visual Systems businesses (“ScioTeq and TREALITY”) to OpenGate Capital for approximately $200 million in cash. ScioTeq and TREALITY were acquired by TransDigm as part of its acquisition of Esterline Technologies Corporation (“Esterline”) in March 2019 and were included in TransDigm’s Airframe segment. Neither ScioTeq or TREALITY met the criteria to be classified as held for sale as of January 2, 2021.

Technical Airborne Components – On April 27, 2021, TransDigm completed the divestiture of the Technical Airborne Components business (“TAC”) to Searchlight Capital Partners for approximately $40 million in cash. TAC was included in TransDigm’s Airframe segment. TAC did not meet the criteria to be classified as held for sale as of January 2, 2021.

The net gain on sale recognized in fiscal 2021 as a result of the ScioTeq and TREALITY and TAC divestitures was approximately $68 million, which was classified as a component of gain on sale of businesses-net within the condensed consolidated statements of income during the third quarter of fiscal 2021.

Racal Acoustics – On January 29, 2021, TransDigm completed the divestiture of the Racal Acoustics business (“Racal”) to Invisio Communications AB (“Invisio”) for approximately $20 million in cash. During the first quarter of fiscal 2021, the Company determined Racal met the criteria to be classified as held for sale. Therefore, the assets and liabilities of Racal, which were not material, have been presented as held for sale in other assets, accrued and other current liabilities and other non-current liabilities, respectively, in the condensed consolidated balance sheets as of January 2, 2021. Racal was acquired by TransDigm as part of its acquisition of Esterline in March 2019 and was included in TransDigm's Non-aviation segment.

Avista, Inc. – On November 17, 2020, TransDigm completed the divestiture of the Avista, Inc. business (“Avista”) to Belcan, LLC (“Belcan”) for approximately $8 million in cash. Avista was acquired by TransDigm as part of its acquisition of Esterline in March 2019 and was included in TransDigm's Airframe segment. The gain on sale recognized in the first quarter of fiscal 2021 as a result of the divestiture was immaterial and classified as a component of gain on sale of businesses-net within the condensed consolidated statements of income.

Souriau-Sunbank Connection Technologies – On December 20, 2019, TransDigm completed the divestiture of the Souriau-Sunbank Connection Technologies business (“Souriau-Sunbank”) to Eaton Corporation plc (“Eaton”) for approximately $920 million. Souriau-Sunbank was acquired by TransDigm as part of its acquisition of Esterline in March 2019 and was included in TransDigm's Non-aviation segment. During the first quarter of fiscal 2022, the Company received approximately $1 million from Eaton related to a final working capital settlement from the Souriau-Sunbank divestiture. These proceeds are classified as income from discontinued operations, net of tax, in the condensed consolidated statements of income.

Accounting Standards Update and Change in Accounting Principle [Abstract]

RECENT ACCOUNTING PRONOUNCEMENTS

RECENT ACCOUNTING PRONOUNCEMENTS

In December 2019, the FASB issued ASU 2019-12, “Income Taxes (Accounting Standards Codification (“ASC”) 740) - Simplifying the Accounting for Income Taxes,” which simplifies the accounting for income taxes by removing certain exceptions to the general principles in ASC 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of ASC 740 by clarifying and amending existing guidance. This guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. The Company adopted ASU 2019-12 on October 1, 2021. The adoption of this standard did not have a material impact on our condensed consolidated financial statements and disclosures.

In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform." Certain amendments were provided for in ASU 2021-01, “Reference Rate Reform (ASC 848): Scope,” which was issued in January 2021. This ASU provides optional guidance for a limited period of time to ease potential accounting impacts associated with transitioning away from reference rates that are expected to be discontinued, such as the London Interbank Offered Rate (“LIBOR”). The amendments in this ASU apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued.

REVENUE RECOGNITION

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 OEMs, various armed forces of the United States and friendly foreign governments, defense OEMs, system suppliers, and various other industrial customers.

The majority of the Company's revenue is recorded at a point in time. Revenue is recognized from the sale of products when control transfers to the customer, which is demonstrated by our right to payment, a transfer of title, a transfer of the risk and rewards of ownership, or the customer acceptance, but most frequently upon shipment where the customer obtains physical possession of the goods.

In some 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 the current year. 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 condensed 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 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):

	January 1, 2022		September 30, 2021
Contract assets, current (1)	$	78	$	72
Contract assets, non-current (2)	1		2

(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.

For the thirteen week period ended January 1, 2022, the revenue recognized that was previously included in contract liabilities was not material.

Refer to Note 13, “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. All provisions for allowances for uncollectible accounts are included in selling and administrative expenses.

As of January 1, 2022 and September 30, 2021, the allowance for uncollectible accounts was $30 million. The allowance for uncollectible accounts is assessed individually at each operating unit by the operating unit’s management team.

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 January 1, 2022 and January 2, 2021, the effective income tax rate was 15.7% and 5.5%, respectively. The Company’s higher effective tax rate for the thirteen week period ended January 1, 2022 was primarily due to the ratio of the discrete impact of excess tax benefits from share-based payments to income from continuing operations being lower in the thirteen week period ended January 1, 2022 resulting from an increase in income from continuing operations before income taxes for the same thirteen week period. The Company’s effective income tax rate of 15.7% for the thirteen week period ended January 1, 2022 was lower than the federal statutory tax rate of 21%, primarily due to the discrete impact of excess tax benefits associated with share-based payments during the first quarter of fiscal 2022.

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 2017. The Company is currently under examination for its federal income taxes in Canada for fiscal years 2013 through 2019, in France for fiscal years 2018 through 2019 and in Germany for fiscal years 2014 through 2017. The Company expects the examinations in France to be completed during fiscal 2022. In addition, the Company is subject to state income tax examinations for fiscal years 2015 and later.

Unrecognized tax benefits at January 1, 2022 and September 30, 2021, the recognition of which would have an impact on the effective tax rate for each fiscal year, amounted to $18.5 million and $19.1 million, respectively. The Company classifies all income tax-related interest and penalties as income tax expense, which were not material for the thirteen week periods ended January 1, 2022 and January 2, 2021. As of January 1, 2022 and September 30, 2021, the Company accrued $4.9 million, respectively, for the potential payment of interest and penalties. Within the next 12 months, it is reasonably possible that unrecognized tax benefits could be reduced by approximately $3.8 million. Any increase in the amount of unrecognized tax benefits within the next 12 months is not expected to be material.

Fair Value Disclosures [Abstract]

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTSThe 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):

		January 1, 2022				September 30, 2021
	Level	Carrying Amount		Fair Value		Carrying Amount		Fair Value

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

(4)The carrying amount of the debt instrument is presented net of debt issuance costs, premium and discount. Refer to Note 9, “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).

Interest rate swaps were measured at fair value using quoted market prices for the swap interest rate indexes over the term of the swap discounted to present value versus the fixed rate of the contract. The interest rate caps were measured at fair value using implied volatility rates of each individual caplet and the yield curve for the related periods.

The Company’s derivative contracts consist of foreign currency exchange contracts and interest rate swap and cap agreements. These derivative contracts are over-the-counter, and their fair value is determined using modeling techniques that include market inputs such as interest rates, yield curves, and currency exchange rates. These contracts are categorized as Level 2 in the fair value hierarchy.

The estimated fair value of the Company’s term loans was based on information provided by the agent under the Company’s senior secured credit facility. The estimated fair values of the Company’s notes were based upon quoted market prices. 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 significant impact to the fair value of derivative assets based on the Company's evaluation of counterparties' credit risks.

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 January 1, 2022 and September 30, 2021.

DERIVATIVES AND HEDGING ACTIVITIES

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 and cap counterparties that contain a provision whereby if the Company defaults on the credit facility the Company could also be declared in default on its swaps and caps, resulting in an acceleration of payment under the swaps and caps.

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 and Cap Agreements – Interest rate swap and cap agreements are used to manage interest rate risk associated with floating-rate borrowings under our credit facility. The interest rate swap and cap 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 through the expiration date of the interest rate swap and cap agreements, thereby reducing the impact of interest rate changes on future interest expense. 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. These derivative instruments qualify as effective cash flow hedges under U.S. GAAP. For these cash flow hedges, the effective portion of the gain or loss from the financial instruments was 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 affected earnings. As the interest rate swap and cap 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.

The following table summarizes the Company's interest rate swap agreements:

Aggregate Notional Amount (in millions)	Start Date	End Date	Related Term Loans	Conversion of Related Variable Rate Debt to Fixed Rate of:
$500	6/29/2018	3/31/2025	Tranche E	5.25% (3.0% plus the 2.25% margin percentage)
$750	6/30/2020	6/30/2022	Tranche E	4.75% (2.5% plus the 2.25% margin percentage)

$900	12/31/2021	6/28/2024	Tranche G	5.35% (3.1% plus the 2.25% margin percentage)
$400	9/30/2022	6/28/2024	Tranche G	5.25% (3.0% plus the 2.25% margin percentage)

The following table summarizes the Company's interest rate cap agreements:

Aggregate Notional Amount (in millions)	Start Date	End Date	Related Term Loans	Offsets Variable Rate Debt Attributable to Fluctuations Above:
$750	6/30/2020	6/30/2022	Tranche E	Three month LIBOR rate of 2.50%
$700	3/31/2023	9/30/2025	Tranche F	Three month LIBOR rate of 1.25%

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):

	January 1, 2022				September 30, 2021
	Asset		Liability		Asset		Liability
Interest rate cap agreements	$	11	$	—	$	8	$	—
Interest rate swap agreements	—		(209)		—		(280)
Net derivatives as classified in the condensed consolidated balance sheets (1)	$	11	$	(209)	$	8	$	(280)

(1)Refer to Note 11, “Fair Value Measurements,” for the condensed consolidated balance sheets classification of our interest rate swap and cap agreements.

Based on the fair value amounts of the interest rate swap and cap agreements determined as of January 1, 2022, the estimated net amount of existing gains and losses and caplet amortization expected to be reclassified into interest expense-net within the next 12 months is approximately $106.3 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 January 1, 2022, the Company had outstanding foreign currency forward exchange contracts to sell U.S. dollars with notional amounts of $97.5 million. The maximum duration of the Company’s foreign currency cash flow hedge contracts at January 1, 2022 is 9 months. These notional values consist of contracts for the Canadian dollar and the European 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 January 1, 2022, the losses reclassified on settlements of foreign currency forward exchange contracts designated as cash flow hedges into net sales were less than $1 million. The losses were previously recorded as a component of accumulated other comprehensive loss in stockholders' deficit.

As of January 1, 2022, the Company expects to record a net loss of approximately $3.7 million on foreign currency forward exchange contracts designated as cash flow hedges to net sales over the next 12 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/electro-mechanical 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 and parachutes. 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/electro-mechanical 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 plans, restructuring costs related to the Company's cost reduction measures in response to the COVID-19 pandemic, foreign currency gains and losses, acquisition-integration costs, acquisition and divestiture transaction-related expenses, and refinancing costs. COVID-19 pandemic restructuring costs represent actions taken by the Company to reduce its workforce to align with customer demand, as well as incremental costs related to the pandemic that are not expected to recur once the pandemic has subsided and are clearly separable from normal operations (e.g., additional cleaning and disinfecting of facilities by contractors above and beyond normal requirements, personal protective equipment). 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 condensed 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 office 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 are allocated to the operating segments.

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

The components of net periodic pension benefit cost, other than service cost, are included in other income in the condensed consolidated statements of income.

Effective June 30, 2021, the Company terminated the Esterline Technologies Retirement Plan (the “ERP”) in accordance with IRS regulations. Pension obligations will be distributed through a combination of lump sum payments to eligible plan participants and the purchase of a group annuity contract. Upon settlement of the pension obligations, the Company will reclassify unrecognized actuarial gains or losses, currently recorded as a component of accumulated other comprehensive loss in stockholders' deficit, to the Company's condensed consolidated statements of income as settlement gains or charges. The Company anticipates the termination process will be completed by the end of fiscal year 2022.

LEASES

Leases [Abstract]

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 12 months or less. Additionally, when accounting for leases, the Company combines payments for leased assets, related services and other components of a lease.

The components of lease expense are as follows (in millions):

Commitments and Contingencies Disclosure [Text Block]

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 $20.8 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 that were too high.

No loss contingency related to the voluntary refund request has been recorded as of January 1, 2022 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.

(1)Of the approximately $697 million of goodwill recognized for the acquisition, approximately $65 million is deductible for tax purposes. Of the approximately $324 million of other intangible assets recognized for the acquisition, approximately $105 million is deductible for tax purposes. The goodwill and intangible assets are deductible over 15 years.

(2)Primarily relates to the recording of loss contract reserves associated with acquired ongoing long-term contracts with customers that were incurring negative gross margins as of the date of acquisition. Based on our review of these contracts, we concluded that the terms of certain contracts were unfavorable when compared to market terms as of the acquisition date. The loss contract reserves, totaling $80.6 million, will be released over an estimated three to five year period.

Accounts Receivable, Allowance for Credit Loss

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. All provisions for allowances for uncollectible accounts are included in selling and administrative expenses.

As of January 1, 2022 and September 30, 2021, the allowance for uncollectible accounts was $30 million. The allowance for uncollectible accounts is assessed individually at each operating unit by the operating unit’s management team.

[1] Primarily relates to opening balance sheet adjustments recorded from the acquisition of CAC up to the expiration of the one year measurement period.

[2] Of the approximately $697 million of goodwill recognized for the acquisition, approximately $65 million is deductible for tax purposes. Of the approximately $324 million of other intangible assets recognized for the acquisition, approximately $105 million is deductible for tax purposes. The goodwill and intangible assets are deductible over 15 years.

[3] Primarily relates to the recording of loss contract reserves associated with acquired ongoing long-term contracts with customers that were incurring negative gross margins as of the date of acquisition. Based on our review of these contracts, we concluded that the terms of certain contracts were unfavorable when compared to market terms as of the acquisition date. The loss contract reserves, totaling $80.6 million, will be released over an estimated three to five year period.
