NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

THIRTY-NINE WEEK PERIODS ENDED JUNE 28, 2025 AND JUNE 29, 2024

(UNAUDITED)

1. BASIS OF PRESENTATION

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

Principles of Consolidation

The financial information included herein is unaudited; however, the information reflects all adjustments (consisting of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the Company’s condensed consolidated financial statements for the interim periods presented. These financial statements and notes should be read in conjunction with the financial statements and related notes for the fiscal year ended September 30, 2024 included in TD Group’s Annual Report on Form 10-K filed on November 7, 2024. 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, 2024 condensed consolidated balance sheet was derived from TD Group’s audited financial statements. The results of operations for the thirty-nine week period ended June 28, 2025 are not necessarily indicative of the results to be expected for the full year.

Reclassifications

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

New Accounting Pronouncements Issued

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” ASU 2023-07 expands disclosures about a public business entity's reportable segments and provides for more detailed information about a reportable segment's expenses. Additionally, ASU 2023-07 requires all segment profit or loss and assets disclosures to be provided on an annual and interim basis. This standard is effective for annual periods beginning after December 15, 2023 (fiscal 2025) and interim periods within fiscal years beginning one year later (fiscal 2026). The Company plans to adopt this standard beginning with our fiscal 2025 Form 10-K. While we expect the adoption of this standard will expand our disclosures within the “Segments” note, we do not expect it to have any impact on our consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires a public business entity to disclose specific categories in its annual effective tax rate reconciliation and disaggregated information about significant reconciling items by jurisdiction and by nature. The ASU also requires entities to disclose their income tax payments (net of refunds) to international, federal, and state and local jurisdictions. The standard makes several other changes to income tax disclosure requirements. This standard is effective for annual periods beginning after December 15, 2024 (fiscal 2026), and requires prospective application with the option to apply it retrospectively. Early adoption is permitted. The Company is currently evaluating this standard to determine its impact on our disclosures.

In November 2024, the FASB issued ASU 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” Additionally, in January 2025, the FASB issued ASU 2025-01 to clarify the effective date of ASU 2024-03. The standard requires, among other items, additional disaggregated disclosures in the notes to financial statements for certain categories of expenses that are included on the face of the statement of income. The standard is effective for fiscal years beginning after December 15, 2026 (fiscal 2028), and for interim periods within fiscal years beginning after December 15, 2027 (fiscal 2029), on a retrospective or prospective basis, with early adoption permitted. The Company is currently evaluating this standard to determine its impact on our disclosures.

2. ACQUISITIONS

Simmonds Precision Products, Inc. – On June 30, 2025, the Company entered into a definitive agreement to acquire all the outstanding stock of the Simmonds Precision Products, Inc. Business (“Simmonds”) of Goodrich Corporation from RTX Corporation for approximately $765 million in cash. The acquisition is subject to regulatory approvals in the United States and customary closing conditions. The acquisition is expected to be financed through existing cash on hand. Simmonds, headquartered in Vergennes, Vermont, is a leading global designer and manufacturer of fuel & proximity sensing and structural health monitoring solutions for the aerospace and defense end markets. The Company’s products are highly engineered, proprietary components with significant aftermarket content and a strong presence across major aerospace and defense platforms.

Servotronics, Inc. – On June 2, 2025, the Company launched a tender offer to acquire all the issued and outstanding stock of Servotronics, Inc. (“Servotronics”), at a price of $47.00 per share in cash. On July 1, 2025, the tender offer expired, resulting in all issued and outstanding stock of Servotronics being canceled and Servotronics becoming a wholly owned subsidiary of the Company. The total purchase price was approximately $133 million in cash, which was financed through existing cash on hand. Servotronics, headquartered in Elma, New York, is a leading global designer and manufacturer of servo controls and other advanced technology components for aerospace and defense applications. Its products are highly engineered, proprietary components with significant aftermarket content and a strong presence across major aerospace and defense platforms. The operating results of Servotronics will be included within TransDigm's Power & Control segment.

Raptor Scientific – On July 31, 2024, the Company acquired all the outstanding stock of Raptor Scientific for approximately $646 million in cash, which includes a working capital settlement of $1 million received in the first quarter of fiscal 2025. The acquisition was financed through existing cash on hand. Raptor Scientific is a leading global manufacturer of complex test and measurement solutions primarily serving the aerospace and defense end markets. Its products are highly engineered, proprietary components with significant aftermarket content and a strong presence across major aerospace and defense platforms. The operating results of Raptor Scientific are included within TransDigm's Airframe segment.

The Company accounted for the acquisition of Raptor Scientific using the acquisition method of accounting and a third-party valuation appraisal and included the results of operations of the acquisition in its condensed consolidated financial statements from the effective date of the acquisition. The total purchase price was allocated to identifiable assets and liabilities based upon the respective fair value at the date 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 are determined based on an income approach, using estimates and assumptions that are deemed reasonable by the Company. Certain assumptions include the discount rates and other assumptions that form the basis of the forecasted results of the acquired business including revenue, earnings before interest, taxes, depreciation and amortization (“EBITDA”), growth rates, royalty rates and technology obsolescence rates. These assumptions are forward looking and could 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 thirty-nine week period ended June 29, 2024 are not material and, accordingly, are not provided.

3. REVENUE RECOGNITION

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

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

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

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

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

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

Table of Contents

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.

We have elected to adopt the practical expedient to not disclose the aggregate amount of transaction price allocated to performance obligations that are unsatisfied as of the end of the reporting period for performance obligations that are part of a contract with an original expected duration of one year or less.

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


	June 28, 2025		September 30, 2024
Contract assets, current (1)	$	265	$	270
Contract assets, non-current (2)	84		31
Total contract assets	349		301
Contract liabilities, current (3)	154		168
Contract liabilities, non-current (4)	8		9
Total contract liabilities	162		177
Net contract assets	$	187	$	124

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

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

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

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

The increase in non-current contract assets is attributable to expected customer billing of certain contracts exceeding one year from June 28, 2025. For the thirteen and thirty-nine week periods ended June 28, 2025, the revenue recognized that was included in the contract liabilities balance at September 30, 2024 was approximately $22 million and $124 million, respectively.

Refer to Note 12, “Segments,” for disclosures related to the disaggregation of revenue.

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

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

As of June 28, 2025 and September 30, 2024, the allowance for uncollectible accounts was $24 million and $32 million, respectively. The allowance for uncollectible accounts is assessed individually at each operating unit by the operating unit’s management team. The reduction in the balance is primarily attributable to a reduction in the assessed risk of the creditworthiness of certain airline customers.

The Company capitalized $14 million in debt issuance costs associated with the 6.375% 2033 Notes during the thirty-nine week period ended June 28, 2025.

Redemption of $2,650 million of Senior Subordinated Notes due 2027 – On June 20, 2025, the Company redeemed all $2,650 million aggregate principal of its outstanding 5.50% 2027 Notes at a redemption price of 100% of the principal amount thereof, plus accrued and unpaid interest thereon to, but not including, the redemption date, using the net proceeds of the offering of the 6.375% 2033 Notes (as further described above), together with existing cash on hand.

The Company recorded refinancing costs of $7 million, consisting of the write-off of $7 million in unamortized debt issuance costs during the thirty-nine week period ended June 28, 2025 in conjunction with the redemption of the 5.50% 2027 Notes.

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

During the first quarter of fiscal 2025, the Company drew the remaining $163 million available under the Securitization Facility, bringing the total drawn to $650 million. At June 28, 2025, the total drawn remained at $650 million. The Securitization Facility bears interest at a rate of Term SOFR plus 1.45%. At June 28, 2025 and September 30, 2024, the applicable interest rate was 5.73% and 6.73%, respectively.

Subsequent Event – Trade Receivable Securitization Facility – On July 11, 2025, the Company amended the Securitization Facility to, among other things, (i) increase the borrowing capacity from $650 million to $725 million; and (ii) extend the maturity date to July 10, 2026 at an interest rate of Term SOFR plus 1.35% compared to an interest rate of Term SOFR plus 1.45% that applied prior to the amendment.

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 June 28, 2025 and September 30, 2024, the outstanding balance of these advances was $12 million and $17 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 $279 million and $262 million at June 28, 2025 and September 30, 2024, respectively. Refer to Note 14, “Leases,” for further disclosure of the Company's lease obligations.

9. 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 June 28, 2025 and June 29, 2024, the effective income tax rate was 22.4% and 23.4%, respectively. During the thirty-nine week periods ended June 28, 2025 and June 29, 2024, the effective income tax rate was 21.9% and 22.5%, respectively. The Company’s lower effective income tax rate for the thirteen week period ended June 28, 2025 was primarily due to a more significant discrete benefit associated with share-based payments along with a less significant increase in the valuation allowance applicable to the Company's net interest deduction limitation compared to the prior period. The Company’s lower effective income tax rate for the thirty-nine week period ended June 28, 2025 was primarily due to a less significant increase in the valuation allowance applicable to Company's net interest deduction limitation, and a lower effective tax rate on non-U.S. earnings, slightly offset by a less significant benefit associated with share-based payments when compared to the same period in 2024. The Company’s effective income tax rate for the thirteen and thirty-nine week periods ended June 28, 2025 was higher than the federal statutory tax rate of 21% primarily due to an increase in the valuation allowance applicable to the Company’s net interest deduction limitation offset by the discrete impact of excess tax benefits associated with share-based payments.

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state, local and foreign jurisdictions. The Company is no longer subject to U.S. federal examinations for years before fiscal 2018. The Company is currently under examination for its federal income taxes in Canada for fiscal years 2013 through 2019, in France for fiscal years 2020 through 2022, and in Germany for fiscal years 2017 through 2019. In addition, the Company is subject to state income tax examinations for fiscal years 2015 and later.

Unrecognized tax benefits at June 28, 2025 and September 30, 2024, the recognition of which would have an impact on the effective tax rate for each fiscal year, amounted to $15 million and $14 million, respectively. The Company classifies all income tax-related interest and penalties as income tax expense, which were not significant for the thirteen and thirty-nine week periods ended June 28, 2025 and June 29, 2024. As of June 28, 2025 and September 30, 2024, the Company accrued $5 million for the potential payment of interest and penalties. Within the next twelve months, it is reasonably possible that unrecognized tax benefits could be reduced by approximately $2 million resulting primarily from the resolution of tax examinations. Any increase in the amount of unrecognized tax benefits within the next twelve months is not expected to be material.

The Organization for Economic Co-operation and Development (the “OECD”) has proposed a framework comprised of rules and models, collectively referred to as Pillar Two (“P2”), that are designed to ensure that certain multi-national enterprises pay a minimum tax rate of 15% on reported profits arising in each jurisdiction where they operate. Although the OECD provided a framework for applying the minimum tax, individual countries have and may continue to enact P2 rules that are different than the OECD framework. While we continue to monitor P2 developments, we do not anticipate that P2 will have a material impact on our financial position in either the near nor the long-term.

On July 4, 2025, the One Big Beautiful Bill Act was signed into law in the U.S., which contains a broad range of tax reform provisions affecting businesses. We are currently evaluating the full effects of the legislation on our estimated annual effective tax rate and cash tax position. As the legislation was signed into law after the close of our third quarter, the impacts are not included in our operating results for the thirty-nine week period ended June 28, 2025.

10. FAIR VALUE MEASUREMENTS

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

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

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

Table of Contents

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

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

The fair value of cash and cash equivalents, trade accounts receivable-net and accounts payable approximated carrying value due to the short-term nature of these instruments at June 28, 2025 and September 30, 2024.

11. DERIVATIVES AND HEDGING ACTIVITIES

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

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

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

During the second quarter of fiscal 2023, we entered into LIBOR to Term SOFR basis interest rate swap and cap transactions to effectively convert our existing swaps and cap from LIBOR-based to Term SOFR-based. The basis swaps and cap offset the LIBOR exposure of the existing swaps and cap and effectively fix the Term SOFR rate for the notional amount. We also entered into forward starting interest rate collar agreements during the second quarter of fiscal 2023. The interest rate collar agreements establish a range where we will pay the counterparties if the three-month Term SOFR rate falls below the established floor rate of 2.00%, and the counterparties will pay us if the three-month Term SOFR rate exceeds the ceiling rate of 3.50%. The collar will settle quarterly from the effective date through the maturity date. No payments or receipts will be exchanged on the interest rate collar contracts unless interest rates rise above or fall below the contracted ceiling or floor rates.

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

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


	June 28, 2025				September 30, 2024
	Asset		Liability		Asset		Liability
Interest rate cap agreement	$	9	$	—	$	20	$	1
Interest rate collar agreements	8		5		3		8
Interest rate swap agreements	11		—		34		1
Net derivatives as classified in the condensed consolidated balance sheets (1)	$	28	$	5	$	57	$	10

(1)Refer to Note 10, “Fair Value Measurements,” for the condensed consolidated balance sheets classification of the Company's interest rate swap, cap and collar agreements.

Based on the fair value amounts determined as of June 28, 2025, the estimated net amount of existing (gains) losses and caplet amortization expected to be reclassified into interest expense-net within the next twelve months is approximately $(1) million.

Table of Contents

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 June 28, 2025, the Company has outstanding foreign currency forward exchange contracts to sell U.S. dollars with notional amounts of $29 million. The maximum duration of the Company’s foreign currency cash flow hedge contracts at June 28, 2025 is three months. These notional values consist of contracts for the Canadian dollar and the euro and are stated in U.S. dollar equivalents at spot exchange rates at the respective trade dates. Amounts related to foreign currency forward exchange contracts included in accumulated other comprehensive loss in stockholders' deficit are reclassified into net sales when the hedged transaction settles. As of June 28, 2025, the Company expects to record a net gain of approximately $(1) million on foreign currency forward exchange contracts designated as cash flow hedges to net sales over the next twelve months. On June 30, 2025, the Company entered into additional foreign currency forward exchange contracts to sell U.S. dollars with notional amounts of $118 million with a maximum duration of fourteen months.

12. SEGMENTS

The Company’s businesses are organized and managed in three reporting segments: Power & Control, Airframe and Non-aviation. Refer to Note 15, “Segments,” 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, 2024, filed on November 7, 2024, for further information on the composition of the Company's segments.

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 option or deferred compensation plans, foreign currency gains and losses, acquisition-integration costs, acquisition transaction-related expenses, and refinancing costs. Acquisition transaction and integration-related expenses and adjustments represent costs incurred to integrate acquired businesses into TD Group’s operations; facility relocation costs and other acquisition-related costs; transaction and valuation-related costs for acquisitions comprising deal fees, legal, financial and tax due diligence expenses; amortization expense of inventory step-up recorded in connection with the purchase accounting of acquired businesses.

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

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

14. LEASES

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

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

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

Forward-looking Statements

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

This Quarterly Report on Form 10-Q contains both historical and “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and 27A of the Securities Act of 1933, as amended. All statements other than statements of historical fact included that address activities, events or developments that we expect, believe or anticipate will or may occur in the future are forward-looking statements, including, in particular, the statements about our plans, objectives, strategies and prospects regarding, among other things, our financial condition, results of operations and business. We have identified some of these forward-looking statements with words like “believe,” “may,” “will,” “should,” “expect,” “intend,” “plan,” “predict,” “anticipate,” “estimate” or “continue” and other words and terms of similar meaning. These forward-looking statements may be contained throughout this Quarterly Report on Form 10-Q. These forward-looking statements are based on current expectations about future events affecting us and are subject to uncertainties and factors relating to, among other things, our operations and business environment, all of which are difficult to predict and many of which are beyond our control. Although we believe that the expectations reflected in these forward-looking statements are reasonable, we do not know whether our expectations will prove correct. They can be affected by inaccurate assumptions we might make or by known or unknown risks and uncertainties, including the risks described in Item 1A, “Risk Factors,” of the Annual Report on Form 10-K. Since our actual results, performance or achievements could differ materially from those expressed in, or implied by, these forward-looking statements, we cannot give any assurance that any of the events anticipated by these forward-looking statements will occur or, if any of them does occur, what impact they will have on our business, results of operations and financial condition. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date they are made. We do not undertake any obligation to update these forward-looking statements or the risk factors contained in this Quarterly Report on Form 10-Q to reflect new information, future events or otherwise, except as may be required under federal securities laws.

Important factors that could cause actual results to differ materially from the forward-looking statements made in this Quarterly Report on Form 10-Q include but are not limited to: the sensitivity of our business to the number of flight hours that our customers’ planes spend aloft and our customers’ profitability, both of which are affected by general economic conditions; supply chain constraints; increases in raw material costs, taxes and labor costs that cannot be recovered in product pricing; failure to complete or successfully integrate acquisitions; our indebtedness; current and future geopolitical or other worldwide events, including, without limitation, wars or conflicts and public health crises; cybersecurity threats; risks related to the transition or physical impacts of climate change and other natural disasters or meeting sustainability-related voluntary goals or regulatory requirements; our reliance on certain customers; the United States (“U.S.”) defense budget and risks associated with being a government supplier including government audits and investigations; failure to maintain government or industry approvals; risks related to changes in laws and regulations, including increases in compliance costs and potential changes in trade policies and tariffs; potential environmental liabilities; liabilities arising in connection with litigation; risks and costs associated with our international sales and operations; and other factors. Refer to Part II, Item 1A included in this Quarterly Report on Form 10-Q and to Part I, 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 believe that our products have strong brand names within the industry and that we have a reputation for high quality, reliability and strong customer support. We believe we have achieved steady, long-term growth in sales and improvements in operating performance we believe that due to our competitive strengths and through execution of our value-driven operating strategy. More specifically, focusing our businesses on our value-driven operating strategy of obtaining profitable new business, carefully controlling the cost structure via productivity and cost improvements and pricing our highly engineered value-added products to fairly reflect the value we provide and the resources required to do so has historically resulted in improvements in gross profit and income from operations over the long-term.

Table of Contents

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

For the third quarter of fiscal 2025, we generated net sales of $2,237 million and net income attributable to TD Group of $492 million. EBITDA As Defined was $1,217 million, or 54.4% 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 net income and net cash provided by operating activities.

For the thirty-nine week period ended June 28, 2025, demand for air travel remained strong both domestically and internationally though recent RPK statistics indicate a softening in the growth rate, particularly in North America and in domestic passenger markets. Commercial aftermarket sales increased for the thirty-nine week period ended June 28, 2025 compared to fiscal 2024 primarily due to the overall strong demand for air travel resulting in higher flight hours and utilization of passenger and freight aircraft as global air traffic continues to surpass pre-pandemic levels. We continue to closely monitor the economic environment, including its impact on airline capacity. At this time, we are seeing minimal impact on our commercial aftermarket.

Our commercial transport original equipment manufacturer (“OEM”) shipments and revenues generally run ahead of aircraft delivery schedules. Consistent with prior years, our fiscal 2025 shipments are a function of, among other things, the estimated 2025 and 2026 commercial aircraft production rates for Boeing and Airbus. Airline demand for new aircraft remains high and the OEMs are working to increase aircraft production. However, aircraft production rates remain well below pre-pandemic levels as the struggles in the OEM supply chain and labor challenges persist. Additional factors such as the recent tariff actions and potentially weakening economic environment, and the Boeing machinist strike, which affected its 737 MAX, 767 and 777 production lines, make it difficult to accurately predict the OEM build rates for the balance of fiscal 2025, though progress continues to be made in the build rates. Airbus has also encountered difficulties in ramping up production. For the thirty-nine week period ended June 28, 2025, the impact across TransDigm's operating units has been uneven and varied, resulting in consolidated commercial OEM sales decreasing compared to fiscal 2024.

Our defense business fluctuates from year-to-year, and is dependent, to a degree, on government budget constraints, the timing of orders, macro and micro dynamics with respect to the U.S. Department of Defense (“DOD”) procurement policy and the extent of global conflicts, such as the ongoing geopolitical conflicts. Likewise, delays in government spending outlays and government funding reprioritization can impact demand. For a variety of reasons, the military spending outlook is very uncertain, though recent DOD budgets have trended upwards due to recent geopolitical challenge and conflicts, and current military modernization efforts. Defense sales for the thirty-nine week period ended June 28, 2025 increased compared to fiscal 2024 primarily due to continued improving United States Government (“U.S. Government”) defense spend outlays.

At various points in 2025, the U.S. Government has announced new or higher tariffs on goods imported into the U.S. from numerous countries resulting in multiple countries countering with reciprocal tariffs and other actions in response. Negotiations between the U.S. and other countries regarding the tariffs are ongoing and their status continues to evolve. TransDigm is primarily a domestic manufacturer as the majority of its operations are in the U.S. and mainly sources in the U.S. for its U.S.-based production. Because of this and other factors such as the applicability of the United States-Mexico-Canada Agreement, we do not expect the tariffs to have a significant impact on our fiscal 2025 operating results. We continue to monitor the developments on tariffs and other changes in trade policy for its potential impact on the economic environment and on our business and operating results.

Changes in Results of Operations

Thirteen week period ended June 28, 2025 compared with the thirteen week period ended June 29, 2024

Total Company

•Net Sales. Net organic sales and acquisition sales and the related dollar and percentage changes for the thirteen week periods ended June 28, 2025 and June 29, 2024 were as follows (amounts in millions):


	Thirteen Week Periods Ended						% Change Net Sales
	June 28, 2025		June 29, 2024		Change
Organic sales	$	2,164	$	2,035	$	129	6.3	%
Acquisition sales	73		11		62		3.0	%
Net sales	$	2,237	$	2,046	$	191	9.3	%

Organic sales represent net sales from existing businesses owned by the Company, excluding sales from acquisitions. Acquisition sales represent net sales from acquired businesses for the period up to one year from the respective acquisition date. We believe this measure provides investors with a supplemental understanding of underlying sales trends by providing sales growth on a consistent basis. Refer to Note 2, “Acquisitions,” in the notes to the condensed consolidated financial statements included herein for information on the Company's recent acquisitions.

The increase in organic sales of $129 million for the thirteen week period ended June 28, 2025 compared to the thirteen week period ended June 29, 2024 is primarily related to increases in defense sales ($122 million, an increase of 15.4%) and commercial aftermarket sales ($35 million, an increase of 5.7%), partially offset by a decrease in commercial OEM sales ($33 million, a decrease of 7.0%). The increase in defense sales is primarily attributable to continued improving U.S. Government defense spend outlays. The increase in commercial aftermarket sales is primarily attributable to the strong demand for air travel resulting in higher flight hours and utilization of aircraft. The decrease in commercial OEM sales is primarily attributable to the prolonged supply chain and labor challenges being encountered by aircraft manufacturers and resulting production delays of new aircraft.

The increase in acquisition sales for the thirteen week period ended June 28, 2025 is primarily attributable to the fiscal 2024 acquisitions of Raptor Scientific, the Electron Device Business of Communications & Power Industries (“CPI's Electron Device Business”) and SEI Industries LTD (“SEI”).

•Cost of Sales and Gross Profit. Cost of sales increased by $79 million, or 9.6%, to $905 million for the thirteen week period ended June 28, 2025 compared to $826 million for the thirteen week period ended June 29, 2024. Cost of sales and the related percentage of net sales for the thirteen week periods ended June 28, 2025 and June 29, 2024 were as follows (amounts in millions):

Table of Contents

Cost of sales during the thirteen week period ended June 28, 2025 slightly increased as a percentage of net sales. This was driven by foreign currency losses recognized in the third quarter of fiscal 2025 as foreign exchange rates, particularly the U.S. dollar compared to the British pound and the euro, weakened in the third quarter of fiscal 2025 compared to fiscal 2024. Excluding the impact of foreign currency losses (gains), cost of sales during the thirteen week period ended June 28, 2025 decreased as a percentage of net sales. This was primarily driven by the application of our three core value-driven operating strategy (obtaining profitable new business, continually improving our cost structure and providing highly engineered value-added products to customers) coupled with fixed overhead costs incurred being spread over a higher production volume.

•Selling and Administrative Expenses. Selling and administrative expenses decreased by $6 million, or 2.4%, to $242 million for the thirteen week period ended June 28, 2025, compared to $248 million, or 12.1% of net sales, for the thirteen week period ended June 29, 2024. Selling and administrative expenses and the related percentage of net sales for the thirteen week periods ended June 28, 2025 and June 29, 2024 were as follows (amounts in millions):


	Thirteen Week Periods Ended
	June 28, 2025			June 29, 2024			Change		% Change
Selling and administrative expenses - excluding costs below	$	190		$	184		$	6	3.3	%
% of net sales	8.5		%	9.0		%
Non-cash stock and deferred compensation expense	46			43			3		7.0	%

Total selling and administrative expenses	$	242		$	248		$	(6)	(2.4)	%
% of net sales	10.8		%	12.1		%

Selling and administrative expenses as a percentage of net sales for the thirteen week period ended June 28, 2025 decreased compared to the thirteen week period ended June 29, 2024 primarily due to the decrease in acquisition transaction-related expenses. Acquisition transaction-related expenses decreased due to a lower volume of business combinations completed quarter-to-date compared to fiscal 2024.

•Amortization of Intangible Assets. Amortization of intangible assets was $51 million for the thirteen week period ended June 28, 2025 compared to $38 million for the thirteen week period ended June 29, 2024. The increase in amortization expense of $13 million was primarily due to the amortization expense recognized on intangible assets from the fiscal 2024 acquisitions.

•Interest Expense-net. Interest expense-net includes interest on borrowings outstanding, amortization of debt issuance costs and original issue discount, revolving credit facility fees, finance leases, interest income and the impact of interest rate swaps and caps designated and qualifying as cash flow hedges. Interest expense-net increased $81 million, or 25.6%, to $397 million for the thirteen week period ended June 28, 2025 from $316 million for the comparable thirteen week period in the prior fiscal year. The increase in interest expense-net was primarily due to an increase in outstanding borrowings and a $25 million decrease in interest income. The weighted average interest rate for cash interest payments on total borrowings outstanding was 6.2% for the thirteen week periods ended June 28, 2025 and June 29, 2024.

•Refinancing Costs. Refinancing costs of $7 million incurred for the thirteen week period ended June 28, 2025 were primarily related to the write-off of unamortized debt issuance costs recorded in conjunction with the redemption of the 5.50% subordinated notes due 2027 (“5.50% 2027 Notes”), which was completed during the thirteen week period ended June 28, 2025. Refinancing costs of $30 million incurred for the thirteen week period ended June 29, 2024 were primarily related to the write-off of unamortized debt issuance costs recorded in conjunction with the redemption of the 6.25% secured notes due 2026 (“2026 Secured Notes”), which was completed during the thirteen week period ended June 29, 2024.

•Other Income. Other income of less than $1 million was recorded for the thirteen week period ended June 28, 2025, which primarily related to royalty and other income and the non-service related components of benefit costs on the Company's benefit plans. Other income of $14 million was recorded for the thirteen week period ended June 29, 2024, which primarily related to royalty and other income and the non-service related components of benefit costs on the Company's benefit plans.

Table of Contents

•Income Tax Provision. Income tax expense as a percentage of income before income taxes was approximately 22.4% for the thirteen week period ended June 28, 2025 compared to 23.4% for the thirteen week period ended June 29, 2024. The Company’s lower effective tax rate for the thirteen week period ended June 28, 2025 was primarily due to a more significant discrete benefit associated with share-based payments along with a less significant increase in the valuation allowance applicable to the Company's net interest deduction limitation compared to the prior period.

•Net Income Attributable to TD Group. Net income attributable to TD Group increased $31 million, or 6.7%, to $492 million for the thirteen week period ended June 28, 2025 compared to net income attributable to TD Group of $461 million for the thirteen week period ended June 29, 2024, primarily as a result of the factors referenced above.

•Earnings per Share. Basic and diluted earnings per share was $8.47 for the thirteen week period ended June 28, 2025 and $7.96 for the thirteen week period ended June 29, 2024.

Business Segments

•Segment Net Sales. Net sales by segment for the thirteen week periods ended June 28, 2025 and June 29, 2024 were as follows (amounts in millions):


	Thirteen Week Periods Ended
	June 28, 2025		% of Net Sales		June 29, 2024		% of Net Sales		Change		% Change
Power & Control	$	1,139	50.9	%	$	1,029	50.3	%	$	110	10.7	%
Airframe	1,058		47.3	%	974		47.6	%	84		8.6	%
Non-aviation	40		1.8	%	43		2.1	%	(3)		(7.0)	%
Net sales	$	2,237	100.0	%	$	2,046	100.0	%	$	191	9.3	%

Net sales for the Power & Control segment increased $110 million, an increase of 10.7%, for the thirteen week period ended June 28, 2025 compared to the thirteen week period ended June 29, 2024. The sales increase resulted primarily from increases in organic sales in defense ($49 million, an increase of 10.1%) and commercial aftermarket ($9 million, an increase of 3.0%). The increase in defense sales is primarily attributable to continued improving U.S. Government defense spend outlays. The increase in commercial aftermarket sales is primarily attributable to the strong demand for air travel resulting in higher flight hours and utilization of aircraft.

Net sales for the Airframe segment increased $84 million, an increase of 8.6%, for the thirteen week period ended June 28, 2025 compared to the thirteen week period ended June 29, 2024. The sales increase resulted primarily from increases in organic sales in defense ($74 million, an increase of 24.6%) and commercial aftermarket ($26 million, an increase of 8.1%). The increase in defense sales and commercial aftermarket sales for the Airframe segment is attributable to the same factors described in the paragraph above for the Power & Control segment.

Acquisition sales for the Power & Control and Airframe segments contributed approximately $62 million in the aggregate to the increase in net sales. Acquisition sales represent net sales from acquired businesses for the period up to one year from the respective acquisition date.

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

Acquisition sales	302		42		260		4.5	%
Net sales	$	6,394	$	5,754	$	640	11.1	%

The increase in organic sales of $380 million for the thirty-nine week period ended June 28, 2025 compared to the thirty-nine week period ended June 29, 2024 is primarily related to increases in defense sales ($271 million, an increase of 12.3%) and commercial aftermarket sales ($168 million, an increase of 9.5%), partially offset by a decrease in commercial OEM sales ($50 million, a decrease of 3.9%). The increase in defense sales is primarily attributable to continued improving U.S. Government defense spend outlays. The increase in commercial aftermarket sales is primarily attributable to the strong demand for air travel resulting in higher flight hours and utilization of aircraft. The decrease in commercial OEM sales is primarily attributable to the prolonged supply chain and labor challenges being encountered by aircraft manufacturers and resulting production delays of new aircraft.

The increase in acquisition sales for the thirty-nine week period ended June 28, 2025 is primarily attributable to the fiscal 2024 acquisitions of Raptor Scientific, CPI's Electron Device Business, SEI and FPT Industries LLC (“FPT”).

Cost of sales during the thirty-nine week period ended June 28, 2025 decreased as a percentage of net sales. This was primarily driven by the application of our three core value-driven operating strategy (obtaining profitable new business, continually improving our cost structure and providing highly engineered value-added products to customers) coupled with fixed overhead costs incurred being spread over a higher production volume.

•Selling and Administrative Expenses. Selling and administrative expenses decreased by $26 million to $689 million, or 10.8% of net sales, for the thirty-nine week period ended June 28, 2025 from $715 million, or 12.4% of net sales, for the thirty-nine week period ended June 29, 2024. Selling and administrative expenses and the related percentage of net sales for the thirty-nine week periods ended June 28, 2025 and June 29, 2024 were as follows (amounts in millions):

Selling and administrative expenses as a percentage of net sales for the thirty-nine week period ended June 28, 2025 decreased compared to the thirty-nine week period ended June 29, 2024 primarily due to the decrease in non-cash stock and deferred compensation expense and acquisition-transaction related expenses. The decrease in non-cash stock and deferred compensation expense is primarily attributable to the appreciation of the stock price at a higher rate during the first nine months of fiscal 2024 compared to the first nine months of fiscal 2025, as the stock price is a key input used to determine the Black-Scholes fair value for the non-cash stock compensation expense, and lower deferred compensation expense. Acquisition transaction-related expenses decreased due to a lower volume of business combinations completed year-to-date compared to fiscal 2024.

•Amortization of Intangible Assets. Amortization of intangible assets was $148 million for the thirty-nine week period ended June 28, 2025 compared to $110 million for the thirty-nine week period ended June 29, 2024. The increase in amortization expense of $38 million was primarily due to the amortization expense recognized on intangible assets from the fiscal 2024 acquisitions.

•Interest Expense-net. Interest expense-net includes interest on borrowings outstanding, amortization of debt issuance costs and original issue discount, revolving credit facility fees, finance leases, interest income and the impact of interest rate swaps and caps designated and qualifying as cash flow hedges. Interest expense-net increased $209 million, or 22.2%, to $1,152 million for the thirty-nine week period ended June 28, 2025 from $943 million for the comparable thirty-nine week period in the prior fiscal year. The increase in interest expense-net was primarily due to an increase in outstanding borrowings and a $62 million decrease in interest income. The weighted average interest rate for cash interest payments on total borrowings outstanding was 6.2% for the thirty-nine week period ended June 28, 2025 compared to 6.1% for the thirty-nine week period ended June 29, 2024.

•Refinancing Costs. Refinancing costs of $7 million incurred for the thirty-nine week period ended June 28, 2025 were primarily related to the write-off of unamortized debt issuance costs recorded in conjunction with the redemption of the 5.50% 2027 Notes. Refinancing costs of $59 million incurred for the thirty-nine week period ended June 29, 2024 were primarily related to the write-off of unamortized debt issuance costs recorded in conjunction with the redemption of the 2026 Secured Notes.

•Other Income. Other income was $31 million for the thirty-nine week period ended June 28, 2025 compared to $24 million recorded for the thirty-nine week period ended June 29, 2024. Other income for the thirty-nine week period ended June 28, 2025 primarily related to a gain on sale of business, royalty and other income and the non-service related components of benefit costs on the Company's benefit plans. Other income for the thirty-nine week period ended June 29, 2024 primarily related to royalty and other income and the non-service related components of benefit costs on the Company's benefit plans.

•Income Tax Provision. Income tax expense as a percentage of income before income taxes was approximately 21.9% for the thirty-nine week period ended June 28, 2025 compared to 22.5% for the thirty-nine week period ended June 29, 2024. The Company’s lower effective tax rate for the thirty-nine week period ended June 28, 2025 was primarily due to a less significant increase in the valuation allowance applicable to Company's net interest deduction limitation, and a lower effective tax rate on non-U.S. earnings, slightly offset by a less significant benefit associated with share-based payments when compared to the same period in 2024.

•Net Income Attributable to TD Group. Net income attributable to TD Group increased $218 million, or 17.5%, to $1,464 million for the thirty-nine week period ended June 28, 2025 compared to net income attributable to TD Group of $1,246 million for the thirty-nine week period ended June 29, 2024, primarily as a result of the factors referenced above.

•Earnings per Share. Basic and diluted earnings per share was $24.31 for the thirty-nine week period ended June 28, 2025 and $19.81 for the thirty-nine week period ended June 29, 2024. Net income attributable to TD Group for the thirty-nine week period ended June 28, 2025 of $1,464 million was decreased by dividend equivalent payments of $49 million, or $0.83 per share, resulting in net income applicable to TD Group common stockholders of $1,415 million. Net income attributable to TD Group for the thirty-nine week period ended June 29, 2024 of $1,246 million was decreased by dividend equivalent payments of $101 million, or $1.75 per share, resulting in net income applicable to TD Group common stockholders of $1,145 million.

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

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

The Company's objective is to maintain an allocation of at least 75% fixed rate and 25% variable rate debt thereby limiting its exposure to changes in near-term interest rates. Interest rate swaps, caps and collars used to hedge and offset, respectively, the variable interest rates on our term loans are further described in Note 11, “Derivatives and Hedging Activities,” in the notes to the condensed consolidated financial statements included herein. As of June 28, 2025, approximately 75% of our gross debt was fixed rate.

As of June 28, 2025, the Company has significant cash liquidity as illustrated in the table presented below (in millions):


	As of June 28, 2025
Cash and cash equivalents	$	2,792
Availability on revolving credit facility	856
Cash liquidity	$	3,648

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 2028.

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

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

Operating Activities. The Company generated $1,531 million of net cash from operating activities during the thirty-nine week period ended June 28, 2025 compared to $1,473 million during the thirty-nine week period ended June 29, 2024.

The change in accounts receivable during the thirty-nine week period ended June 28, 2025 was a use of cash of $126 million compared to a use of cash of $22 million during the thirty-nine week period ended June 29, 2024. The increase in the use of cash of $104 million is primarily attributable to the timing of cash receipts. The Company continues to actively manage its accounts receivable, the related agings and collection efforts.

The change in inventories during the thirty-nine week period ended June 28, 2025 was a use of cash of $167 million compared to a use of cash of $140 million during the thirty-nine week period ended June 29, 2024. The slight increase in the use of cash is due to an increase in raw materials to support the expected higher fourth quarter sales activity compared to prior year. The Company continues to actively and strategically manage inventory levels in response to the ongoing supply chain challenges.

The change in accounts payable during the thirty-nine week period ended June 28, 2025 was a source of cash of $1 million compared to a use of cash of $9 million during the thirty-nine week period ended June 29, 2024. The change is due to the timing of payments to suppliers.

Draws on the revolving commitments are subject to an interest rate of Term SOFR plus 2.25%. The unused portion of the revolving commitments is subject to a fee of 0.5% per annum. The maturity date of the revolving credit facility is February 27, 2029.

The interest rates per annum applicable to the Term Loans Facility under the Second Amended and Restated Credit Agreement dated as of June 4, 2014 (the “Credit Agreement”) are, at TransDigm’s option, equal to either an alternate base rate or an adjusted Term SOFR for one, three or six-month interest periods chosen by TransDigm, in each case plus an applicable margin percentage. The adjusted Term SOFR related to the Term Loans Facility are not subject to a floor. Refer to Note 11, “Derivatives and Hedging Activities,” in the notes to the condensed consolidated financial statements included herein for information about how our interest rate swap, cap and collar agreements are used to hedge and offset, respectively, the variable interest rate portion of our debt.

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

Guarantor Information

The Subordinated Notes are subordinated to all of our existing and future senior secured debt, including indebtedness under TransDigm’s existing senior secured credit facilities, rank equally with all of our existing and future senior subordinated debt and rank senior to all of our future debt that is expressly subordinated to the Subordinated Notes. The 4.625% 2029 Notes and the 4.875% 2029 Notes are fully and unconditionally guaranteed on a senior subordinated unsecured basis by TD Group, TransDigm UK and TransDigm Inc.’s Domestic Restricted Subsidiaries (as defined in the applicable indentures). The 6.375% 2033 Notes are guaranteed, on a senior subordinated basis, by TransDigm Group and each of TransDigm Inc.’s direct and indirect restricted subsidiaries that is a borrower or guarantor under TransDigm’s senior secured credit facilities or that issues or guarantees any capital markets indebtedness of TransDigm or any of the guarantors in an aggregate principal amount of at least $200 million. The table set forth in Exhibit 22.1 filed with this Form 10-Q details the primary obligors and guarantors. The guarantees of the Subordinated Notes are subordinated to all of the guarantors’ existing and future senior debt, rank equally with all of their existing and future senior subordinated debt and rank senior to all of their future debt that is expressly subordinated to the guarantees of the Subordinated Notes. The Subordinated Notes are structurally subordinated to all of the liabilities of TD Group’s non-guarantor subsidiaries.

Table of Contents

The Secured Notes are senior secured debt of TransDigm and rank equally in right of payment with all of TransDigm’s existing and future senior secured debt, including indebtedness under TransDigm’s existing senior secured credit facilities, and are senior in right of payment to all of TransDigm’s existing and future senior subordinated debt, including the Subordinated Notes. The 2028 Secured Notes are guaranteed on a senior secured basis by TD Group, TransDigm UK and TransDigm Inc.’s Domestic Restricted Subsidiaries (as defined in the applicable indentures). The 2029 Secured Notes, 2030 Secured Notes, 2031 Secured Notes, 2032 Secured Notes and 2033 Secured Notes are guaranteed on a senior secured basis by TD Group and each of TransDigm Inc.’s direct and indirect Restricted Subsidiaries (as defined in the applicable indenture) that is a borrower or guarantor under TransDigm’s senior secured credit facilities or that issues or guarantees any capital markets indebtedness of TransDigm Inc. or any of the guarantors in an aggregate principal amount of at least $200 million. As of the date of this Form 10-Q, the guarantors of the 2029 Secured Notes, 2030 Secured Notes, 2031 Secured Notes, 2032 Secured Notes and 2033 Secured Notes are the same as the guarantors of the 2028 Secured Notes. The table set forth in Exhibit 22.1 filed with this Form 10-Q details the primary obligors and guarantors. The guarantees of the Secured Notes rank equally in right of payment with all of the guarantors’ existing and future senior secured debt and are senior in right of payment to all of their existing and future senior subordinated debt. The Secured Notes are structurally subordinated to all of the liabilities of TransDigm’s non-guarantor subsidiaries.

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

The financial information presented is that of TD Group, TransDigm Inc. and the other Guarantors, which includes TransDigm UK, on a combined basis and the financial information of non-issuer and non-guarantor subsidiaries has been excluded.

Certain Restrictive Covenants in Our Debt Documents

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

The restrictive covenants included in the Credit Agreement are subject to amendments executed periodically. The most recent amendment that impacted the restrictive covenants contained in the Credit Agreement is Amendment No. 15, executed on March 22, 2024.

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.

Table of Contents

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

With the exception of the revolving credit facility, the Company has no maintenance covenants in its existing term loan and indenture agreements. Under the Credit Agreement, if the usage of the revolving credit facility exceeds 40% (or, currently, $364 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 7.50x (or, solely with respect to the first four fiscal quarters ending after the consummation of any material acquisition, 8.00x) as of the last day of the fiscal quarter.

As of June 28, 2025, the Company was in compliance with all of its debt covenants and expects to remain in compliance with its debt covenants in subsequent periods.

Trade Receivable Securitization Facility

During fiscal 2014, the Company established a trade receivable securitization facility (the “Securitization Facility”). The Securitization Facility effectively increases the Company’s borrowing capacity depending on the amount of the domestic operations’ trade accounts receivable. The Securitization Facility is collateralized by substantially all of the Company’s 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 11, 2025, the Company amended the Securitization Facility to, among other things, (i) increase the borrowing capacity from $650 million to $725 million; and (ii) extend the maturity date to July 10, 2026 at an interest rate of Term SOFR plus 1.35% compared to an interest rate of Term SOFR plus 1.45% that applied prior to the amendment.

Dividend and Dividend Equivalent Payments

Pursuant to the Fourth Amended and Restated TransDigm Group Incorporated 2006 Stock Incentive Plan Dividend Equivalent Plan, the Amended and Restated 2014 Stock Option Plan Dividend Equivalent Plan and the 2019 Stock Option Plan Dividend Equivalent Plan, all of the vested options granted under the existing stock option plans, except for grants to the members of the Board of Directors, are entitled to certain dividend equivalent payments in the event of the declaration of a dividend by the Company. In August 2022, all members of the Board of Directors at that time executed amendments to their option agreements resulting in the directors no longer receiving dividend equivalent payments in cash, but rather for dividends declared after June 1, 2022, dividends result in a reduction of strike price.

No dividends were declared in the thirty-nine week period ended June 28, 2025. In September 2024, TransDigm's Board of Directors authorized and declared a special cash dividend of $75.00 on each outstanding share of common stock. On October 18, 2024, the Company paid the special cash dividend, totaling $4,216 million. Dividend equivalent payments are made during the Company's first fiscal quarter each year and also upon payment of any dividends declared. Total dividend equivalent payments in the first quarter of fiscal 2025 were approximately $180 million, $131 million of which was associated with the September 2024 special dividend declaration.

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

Off-Balance Sheet Arrangements

The Company utilizes letters of credit to back certain payment and performance obligations. Letters of credit are subject to limits based on amounts outstanding under the Company’s revolving credit facility. As of June 28, 2025, the Company had $54 million in letters of credit outstanding.

Non-GAAP Financial Measures

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

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

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

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

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

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

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

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

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

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

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

As of June 28, 2025, 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.

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 13, “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, 2024, filed on November 7, 2024.
