NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

TWENTY-SIX WEEK PERIODS ENDED MARCH 31, 2018 AND APRIL 1, 2017

(UNAUDITED)

1. DESCRIPTION OF THE BUSINESS

Description of the Business – TransDigm Group Incorporated (“TD Group”), through its wholly-owned subsidiary, TransDigm Inc., is a leading global designer, producer and supplier of highly engineered aircraft components for use on nearly every commercial and military aircraft in service today. TransDigm Inc., along with TransDigm Inc.’s direct and indirect wholly-owned operating subsidiaries (collectively, with TD Group, the “Company” or “TransDigm”), offers a broad range of proprietary aerospace components. TD Group has no significant assets or operations other than its 100% ownership of TransDigm Inc. TD Group’s common stock is listed on the New York Stock Exchange, or the NYSE, under the trading symbol “TDG.”

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, NiCad batteries and chargers, engineered latching and locking devices, rods and locking devices, engineered connectors and elastomers, databus and power controls, cockpit security components and systems, specialized cockpit displays, aircraft audio systems, specialized lavatory components, seat belts and safety restraints, engineered interior surfaces and related components, lighting and control technology, military personnel parachutes, high performance hoists, winches and lifting devices, and cargo loading, handling and delivery systems.

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 financial position and results of operations and cash flows for the interim periods presented. These financial statements and notes should be read in conjunction with the financial statements and related notes for the year ended September 30, 2017 included in TD Group’s Form 10-K filed on November 13, 2017. As disclosed therein, the Company’s annual consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States (“GAAP”). The September 30, 2017 condensed consolidated balance sheet was derived from TD Group’s audited financial statements. The results of operations for the twenty-six week period ended March 31, 2018 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 related to the designation of Schroth as discontinued operations beginning in the fourth quarter of fiscal 2017 (refer to Note 14, "Discontinued Operations," for further information) and an organizational realignment effective October 1, 2017 of certain businesses comprising the Power & Control and the Non-Aviation segments.

3. ACQUISITIONS AND DIVESTITURES

During the twenty-six week period ended March 31, 2018, the Company completed the acquisition of the Kirkhill elastomers business ("Kirkhill") from Esterline Technologies. During the fiscal year ended September 30, 2017, the Company completed the acquisitions of three separate aerospace product lines (collectively, the "Third Quarter 2017 Acquisitions"). The Company accounted for the acquisitions using the acquisition method and included the results of operations of the acquisitions in its condensed consolidated financial statements from the effective date of each acquisition. As of March 31, 2018, the one-year measurement period is open for Kirkhill and the Third Quarter 2017 Acquisitions; therefore, the assets acquired and liabilities assumed related to these acquisitions are subject to adjustment until the end of their respective one-year measurement periods. Pro forma net sales and results of operations for the acquisitions had they occurred at the beginning of the applicable twenty-six week period ended March 31, 2018 or April 1, 2017 are not material and, accordingly, are not provided.

The acquisitions strengthen and expand the Company’s position to design, produce and supply highly engineered proprietary aerospace components in niche markets with significant aftermarket content and provide opportunities to create value through the application of our three core value-driven operating strategies (obtaining profitable new business, improving our cost structure, and providing highly engineered value-added products to customers). The purchase price paid for each 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.

Table of Contents

Kirkhill – On March 15, 2018, the Company acquired the assets and certain liabilities of the Kirkhill elastomers business from Esterline Technologies for a total purchase price of approximately $50 million in cash subject to purchase price adjustments. Kirkhill's products are primarily proprietary, sole source with significant aftermarket content and used in a broad variety of most major commercial transport and military platforms. Kirkhill is also well represented on newer commercial platforms such as Boeing’s 787, 777X and 737MAX; Airbus’s A320NEO and A350; as well as the military JSF. Kirkhill is included in TransDigm's Airframe segment. The Company expects that no goodwill recognized for the acquisition will be deductible for tax purposes.

Third Quarter 2017 Acquisitions – The Third Quarter 2017 Acquisitions were acquired for an aggregate purchase price of approximately $106.7 million in cash, which includes working capital settlements totaling $1.0 million paid in the third and fourth quarters of 2017 and an earn-out of $0.4 million paid in the second quarter of 2018. All three product lines consist primarily of proprietary, sole source products with significant aftermarket content. The products include highly engineered aerospace controls, quick disconnect couplings, and communication electronics. Each product line acquired was consolidated into an existing TransDigm reporting unit within TransDigm's Power & Control segment. The Company expects that approximately $66 million of goodwill recognized for the acquisitions will be deductible for tax purposes over 15 years and approximately $9 million of goodwill recognized for the acquisitions will not be deductible for tax purposes.

Schroth – On February 22, 2017, the Company acquired all of the outstanding stock of Schroth Safety Products GmbH and certain aviation and defense assets and liabilities from subsidiaries of Takata Corporation (collectively, "Schroth"), for a total purchase price of approximately $89.7 million, which consisted primarily of $79.7 million paid in cash during fiscal 2017 and an approximately $9.0 million indemnity holdback, of which $8.5 million was paid in April 2018.

On January 26, 2018, the Company completed the sale of Schroth in a management buyout to a private equity fund and certain members of Schroth management for approximately $61.4 million, subject to a working capital adjustment. Further disclosure related to Schroth’s discontinued operations is included in Note 14.

4. RECENT ACCOUNTING PRONOUNCEMENTS

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2014-09, which created a new topic in the Accounting Standards Codification (“ASC”) 606, “Revenue From Contracts With Customers.” In addition to superseding and replacing nearly all existing U.S. GAAP revenue recognition guidance, including industry-specific guidance, ASC 606 establishes a new control-based revenue recognition model. The new revenue standards may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. The guidance is effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2018, which is the Company’s planned date of adoption. The Company expects to use the modified retrospective method. The Company is continuing to evaluate the impact of the standard. For each reporting unit, we have evaluated a representative sample of contracts and other agreements with our customers and evaluated the provisions contained within these contracts and agreements in consideration of the five step model specified within ASC 606. We are in the process of documenting the impact of the standard on our current accounting policies and practices in order to identify material differences, if any, that would result from applying the new requirements to our revenue contracts. We continue to make progress on our assessment of ASC 606 and are also in the process of evaluating the impact, if any, on changes to our business processes, systems, and controls to support recognition and disclosure requirements under ASC 606.

In February 2016, the FASB issued ASU 2016-02, “Leases (ASC 842),” which will require that a lessee recognize assets and liabilities on the balance sheet for all leases with a lease term of more than twelve months, with the result being the recognition of a right of use asset and a lease liability. The guidance is effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2019, with early adoption permitted. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements and disclosures.

In June 2016, the FASB issued ASU 2016-13, "Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments (ASU 2016-13)," which changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for losses. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted for annual and interim periods beginning after December 15, 2018. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements and disclosures.

Table of Contents

In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows—Classification of Certain Cash Receipts and Cash Payments," which clarifies existing guidance related to accounting for cash receipts and cash payments and classification on the statement of cash flows. This guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with early adoption permitted. The Company elected to early adopt this standard in the fourth quarter of fiscal 2017. The adoption of this standard did not have a material impact on its consolidated statement of cash flows.

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment,” to eliminate Step 2 from the goodwill impairment test in order to simplify the subsequent measurement of goodwill. The guidance is effective for fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The adoption of this standard is not expected to have a material impact on its consolidated financial statements and disclosures.

In March 2017, the FASB issued ASU 2017-07, "Compensation—Retirement Benefits (ASC 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost," that will change how employers that sponsor defined benefit and/or other postretirement benefit plans present the net periodic benefit cost in the income statement. Under the new guidance, employers will present the service cost component of the net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. In addition, only the service cost component will be eligible for capitalization in assets. Employers will present the other components separately from the line item(s) that includes the service cost and outside of any subtotal of operating income, if one is presented. Employers will have to disclose the line(s) used to present the other components of net periodic benefit cost, if the components are not presented separately in the income statement.The standard is effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within the fiscal year. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. The adoption of this standard is not expected to have a material impact on our consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, "Compensation—Stock Compensation (ASC 718): Scope of Modification Accounting," which provides clarity on which changes to the terms or conditions of share-based payment awards require an entity to apply the modification accounting provisions required in ASC 718. The standard is effective for all entities for annual periods beginning after December 15, 2017, with early adoption permitted, including adoption in any interim period for which financial statements have not yet been issued. The adoption of this standard is not expected to have a material impact on our consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging (ASC 815): Targeted Improvements to Accounting for Hedging Activities,” which amends the FASB’s hedge accounting model to enable entities to better portray their risk management activities in financial statements. The guidance eliminates the requirement to separately measure and report hedge ineffectiveness and generally requires the entire change in the fair value of a hedging instrument to be presented in the same income statement line as the hedged item. The guidance also eases certain documentation and assessment requirements and modifies the accounting for components excluded from the assessment of hedge effectiveness. ASU 2017-12 is effective for the Company for annual reporting periods, including interim periods therein, beginning October 1, 2018, with early adoption permitted. As early adoption is permissible, the Company adopted the pronouncement beginning October 1, 2017. Changes were applied prospectively in accordance with the standard and prior periods were not adjusted. The adoption of this standard did not have a material impact on our consolidated financial statements and disclosures.

In February 2018, the FASB issued ASU 2018-02, "Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income," which gives entities the option to reclassify tax effects stranded in accumulated other comprehensive income as a result of the Tax Cuts and Jobs Act (the "Act") into retained earnings. The guidance allows entities to reclassify from accumulated other comprehensive income to retained earnings stranded tax effects resulting from the Act's new federal corporate income tax rate. The guidance also allows entities to elect to reclassify other stranded tax effects that relate to the Act but do not directly relate to the change in the federal tax rate (e.g., state taxes, changing from a worldwide tax system to a territorial system). Tax effects that are stranded in accumulated other comprehensive income for other reasons (e.g., prior changes in tax law, a change in valuation allowance) may not be reclassified. The standard is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within the fiscal year. Early adoption is permitted, including adoption in any interim period for which financial statements have not yet been issued. Entities have the option to apply the guidance retrospectively or in the period of adoption. The adoption of this standard is not expected to have a material impact on our consolidated financial statements.

In March 2018, the FASB issued ASU 2018-05, “Income Taxes (Topic 740), Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118.” The ASU adds various SEC paragraphs pursuant to the issuance of the December 2017 SEC Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which was effective immediately. The SEC issued SAB 118 to address concerns about reporting entities’

ability to timely comply with the accounting requirements to recognize all of the effects of the Tax Cuts and Jobs Act in the period of enactment. SAB 118 allows disclosure that timely determination of some or all of the income tax effects from the Tax Cuts and Jobs Act are incomplete by the due date of the financial statements and if possible to provide a reasonable estimate. We have accounted for the tax effects of the Tax Cuts and Jobs Act under the guidance of SAB 118, on a provisional basis. Our accounting for certain income tax effects is incomplete, but we have determined reasonable estimates for those effects and have recorded provisional amounts in our condensed consolidated financial statements. Refer to Note 9, "Income Taxes," for further information.

Amendment No.4 to the Second Amended and Restated Credit Agreement - On November 30, 2017, the Company entered into Amendment No. 4 to the Second Amended and Restated Credit Agreement. Pursuant to Amendment No. 4, TransDigm, among other things, converted approximately $798 million of existing tranche D term loans into additional tranche F term loans and decreased the margin applicable to the existing tranche E term loans and tranche F term loans to LIBO rate plus 2.75% per annum. The terms and conditions (other than maturity date) that apply to the tranche F term loans, including pricing, are substantially the same as the terms and conditions that apply to the tranche D term loans immediately prior to Amendment No. 4.

The Company capitalized $2.9 million and expensed $0.7 million of refinancing costs representing debt issuance costs associated with Amendment No. 4 during the twenty-six week period ended March 31, 2018. Additionally, the Company wrote off $0.5 million in unamortized debt issuance costs related to the tranche D term loans that were converted to tranche F term loans and wrote off $0.2 million in unamortized debt issuance costs related to the tranche F terms loans.

Refinancing Facility Agreement to the Second Amended and Restated Credit Agreement - On February 22, 2018, the Company entered into a refinancing facility agreement. TransDigm, among other things, incurred new tranche G term loans in an aggregate principal amount equal to $1,809 million and repaid in full all of the existing tranche G term loans outstanding under the Second and Amended Restated Credit Agreement immediately prior to the refinancing facility agreement. The refinancing facility agreement also decreased the margin applicable to the tranche G term loans to LIBO rate plus 2.5% per annum. The terms and conditions that apply to the tranche G term loans, including pricing, are substantially the same as the terms and conditions that apply to the tranche G term loans immediately prior to the refinancing facility agreement.

Additionally, the Company wrote off $0.2 million in unamortized debt issuance costs related to the tranche G terms loans.

9. INCOME TAXES

The Tax Cuts and Jobs Act (the "Act") was enacted on December 22, 2017. The Act reduces the U.S. federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign-sourced earnings. The rate change is administratively effective at the beginning of our fiscal year (October 1, 2017), using a blended rate for the annual period. As a result, the blended statutory tax rate for the year is 24.5%. At March 31, 2018, we had not completed our accounting for the tax effects of enactment of the Act; however, in certain cases, we have made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. We have recognized a provisional benefit amount of $170.2 million related to the remeasurement of our deferred tax balance for the twenty-six week period ended March 31, 2018. However, we are still analyzing certain aspects of the Act and refining our calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. In addition, we have recognized a provisional expense amount of $23.1 million for our one-time transition tax liability for the twenty-six week period ended March 31, 2018. The one-time transition tax is based on our total post-1986 earnings and profits ("E&P") that we previously deferred from U.S. income taxes and is based in part on the amount of those earnings held in cash and other specified assets. However, we continue to refine the calculation of the total post-1986 E&P for our foreign subsidiaries. This amount may change when we finalize the calculation of post-1986 foreign E&P previously deferred from US federal taxation and finalize the amounts held in cash or other specified assets. As a result of the Act, we recognized a net provisional benefit amount of $147.1 million as a discrete tax benefit, which is included as a component of income tax expense from continuing operations for the twenty-six week period ended March 31, 2018.

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 March 31, 2018 and April 1, 2017, the effective income tax rate was 18.3% and 27.7%, respectively. During the twenty-six week periods ended March 31, 2018 and April 1, 2017, the effective income tax rate was (17.3)% and 22.5%, respectively. The Company's lower effective tax rate for the thirteen week ended March 31, 2018 was primarily due to the reduction in the U.S. federal corporate statutory rate related to the enactment of the Act. The Company’s lower effective tax rate for the twenty-six week period ended March 31, 2018 was primarily due to the reduction in the U.S. federal corporate tax rate as well as discrete adjustments related to the enactment of the Act described above. The Company’s effective tax rate for the thirteen and twenty-six week periods ended March 31, 2018 was lower than the Federal statutory tax rate primarily due to enactment of the Act described above. The Company’s effective tax rate for the thirteen and twenty-six periods ended April 1, 2017 was lower than the Federal statutory tax rate primarily due to excess tax benefits from share based payments, the domestic manufacturing deduction and foreign earnings taxed at rates lower than the U.S. statutory rate.

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction, various state and local jurisdictions as well as foreign jurisdictions located in Belgium, Canada, China, France, Germany, Hong Kong, Hungary, Japan, Malaysia, Mexico, Norway, Singapore, Sri Lanka, Sweden and the United Kingdom. The Company is no longer subject to U.S. federal examinations for years before fiscal 2014. The Company is currently under U.S. federal examination for fiscal 2014. In addition, the Company is subject to state income tax examinations for fiscal years 2009 and later.

At March 31, 2018 and September 30, 2017, TD Group had $8.8 million and $8.7 million in unrecognized tax benefits, the recognition of which would have an effect of approximately $8.7 million on the effective tax rate at March 31, 2018 and September 30, 2017, respectively. The Company believes the tax positions that comprise the unrecognized tax benefits will be reduced by approximately $0.6 million over the next 12 months. The Company recognizes accrued interest and penalties related to unrecognized tax benefits in income tax expense.

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 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 using unobservable inputs.

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 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 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 book value due to the short-term nature of these instruments at March 31, 2018 and September 30, 2017.

11. DERIVATIVES AND HEDGING ACTIVITIES

The Company is exposed to, among other things, the impact of changes in 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. The Company has agreements with each of its

Table of Contents

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.

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 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:
$1,000	9/30/2014	6/30/2019	Tranche G	4.90% (2.40% plus the 2.50% margin percentage)
$400	9/30/2017	9/30/2022	Tranche G	4.40% (1.90% plus the 2.50% margin percentage)

All interest rate swap and cap agreements are recognized in our condensed consolidated balance sheets at fair value. 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 long-term 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 sheet and the net amounts of assets and liabilities presented therein.

Table of Contents

Based on the fair value amounts of the interest rate swap and cap agreements determined as of March 31, 2018, the estimated net amount of existing gains and losses and caplet amortization expected to be reclassified into interest expense within the next twelve months is approximately $2.1 million.

Effective September 30, 2016, the Company redesignated the interest rate cap agreements related to the $400 million and the $750 million aggregate notional amount with cap rates of 2.0% and 2.5%, respectively, based on the expected probable cash flows associated with the 2016 term loans and 2015 term loans in consideration of the Company’s ability to select one-month, two-month, three-month, or six-month LIBO rate set forth in the Second Amended and Restated Credit Agreement. Accordingly, amounts previously recorded as a component of accumulated other comprehensive loss in stockholder’s deficit amortized into interest expense was $2.0 million and $1.9 million for the twenty-six week periods ended March 31, 2018 and April 1, 2017, respectively. The accumulated other comprehensive loss to be reclassified into interest expense over the remaining term of the cap agreements is $8.9 million with a related tax benefit of $2.4 million as of March 31, 2018.

Effective December 30, 2017, the Company redesignated the existing interest rate swap agreements related to the $750 million, $500 million, $1,000 million and $750 million aggregate notional amounts with swap rates of 5.25%, 4.65%, 4.55% and 5.55%, respectively, based on the expected probable cash flows associated with the tranche F term loans in consideration of the Company’s removal of the LIBO rate floor on the tranche F term loans as set forth in Amendment No. 4 to the Second Amended and Restated Credit Agreement. Accordingly, the amount recorded as a component of accumulated other comprehensive loss in stockholders’ deficit related to these redesignated interest rate swap hedges will be amortized into earnings based on the original maturity date of the related interest rate swap agreements. Accordingly, amounts previously recorded as a component of accumulated other comprehensive loss in stockholder’s deficit amortized into interest expense was $0.3 million for the twenty-six week period ended March 31, 2018. The accumulated other comprehensive gain to be reclassified into interest expense over the remaining term of the swap agreements is immaterial.

Effective March 31, 2018, the Company redesignated the existing interest rate swap agreements related to the $1,000 million and the $400 million aggregate notional amount with swap rates of 4.90% and 4.40%, respectively, based on the expected probable cash flows associated with the tranche G term loans in consideration of the Company’s removal of the LIBO rate floor on the tranche G term loans as set forth in the refinancing facility agreement dated February 22, 2018 related to the Second Amended and Restated Credit Agreement. Accordingly, the amount recorded as a component of accumulated other comprehensive loss in stockholders’ deficit related to these redesignated interest rate swap hedges of approximately $12.8 million with a related tax expense of $3.1 million as of March 31, 2018, will be amortized into earnings based on the original maturity date of the related interest rate swap agreements.

Table of Contents

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 refinancing costs, acquisition-related costs, transaction-related costs and non-cash compensation charges incurred in connection with the Company’s stock option plans. Acquisition-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 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 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 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 insignificant for the periods presented below. Certain corporate-level expenses are allocated to the operating segments.

Effective October 1, 2017, the Company made an organizational realignment of certain businesses comprising the Power & Control, Airframe and the Non-Aviation segments. Operating results for the thirteen and twenty-six week periods ended April 1, 2017 and total assets as of September 30, 2017 were reclassified to conform to the presentation for the thirteen and twenty-six week periods ended March 31, 2018.

Forward-looking Statements

The following discussion of the Company’s financial condition and results of operations should be read together with TD Group’s 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 includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, including, in particular, the statements about the Company’s plans, strategies and prospects under this section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations.” When used in this Quarterly Report on Form 10-Q, the words “believe,” “may,” “will,” “should,” “expect,” “intend,” “plan,” “predict,” “anticipate,” “estimate” or “continue” and other words and terms of similar meaning are intended to identify forward-looking statements. Although the Company believes that its plans, intentions and expectations reflected in or suggested by such forward-looking statements are reasonable, such forward-looking statements are subject to a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements made in this report.

Some of our more significant 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, NiCad batteries and chargers, engineered latching and locking devices, rods and locking devices, engineered connectors and elastomers, databus and power controls, cockpit security components and systems, specialized cockpit displays, aircraft audio systems, specialized lavatory components, seat belts and safety restraints, engineered interior surfaces and related components, lighting and control technology, military personnel 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 second quarter of fiscal 2018, we generated net sales of $933.1 million and net income of $196.3 million. EBITDA As Defined was $463.1 million, or 49.6% of net sales. See 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.

Critical Accounting Policies and Estimates

The preparation and fair presentation of the consolidated unaudited interim financial statements and accompanying notes included in this report are the responsibility of management. The financial statements and footnotes have been prepared in accordance with U.S. generally accepted accounting principles for interim financial statements and contain certain amounts that were based upon management’s best estimates, judgments and assumptions that were believed to be reasonable under the circumstances. On an ongoing basis, we evaluate the accounting policies and estimates used to prepare financial statements. Estimates are based on historical experience, judgments and assumptions believed to be reasonable under current facts and circumstances. Actual amounts and results could differ from these estimates used by management.

Changes in Results of Operations

Thirteen week period ended March 31, 2018 compared with the thirteen week period ended April 1, 2017

Total Company


•	Net Sales. Net organic sales and acquisition sales and the related dollar and percentage changes for the thirteen week periods ended March 31, 2018 and April 1, 2017 were as follows (amounts in millions):



	Thirteen Week Periods Ended						% Change Total Sales
	March 31, 2018		April 1, 2017		Change		% Change Total Sales
Organic sales	$	925.6	$	868.7	$	56.9	6.6	%
Acquisition sales	7.5		—		7.5		0.8	%
	$	933.1	$	868.7	$	64.4	7.4	%

The increase in organic sales is primarily related to an increase in commercial aftermarket sales of $43.7 million, or 14.6%, and an increase in defense sales of $13.2 million, or 4.7%. This was partially offset by a decrease in organic commercial OEM sales of $5.2 million, or 2.1%.

Acquisition sales represent sales of acquired businesses for the period up to one year subsequent to their acquisition dates. The amount of acquisition sales shown in the table above for the thirteen week period ended March 31, 2018 was attributable to the Third Quarter 2017 Acquisitions described in Note 3, "Acquisitions and Divestitures."


•	Cost of Sales and Gross Profit. Cost of sales increased by $19.7 million, or 5.2%, to $399.0 million for the thirteen week period ended March 31, 2018 compared to $379.3 million for the thirteen week period ended April 1, 2017. Cost of sales and the related percentage of total sales for the thirteen week periods ended March 31, 2018 and April 1, 2017 were as follows (amounts in millions):



	Thirteen Week Periods Ended
	March 31, 2018			April 1, 2017			Change			% Change
Cost of sales - excluding costs below	$	395.2		$	374.4		$	20.8		5.6	%
% of total sales	42.4		%	43.1		%
Inventory purchase accounting adjustments	—			2.8			(2.8		)	(100.0	)%
% of total sales	—		%	0.3		%
Acquisition integration costs	2.6			1.0			1.6			160.0	%
% of total sales	0.3		%	0.1		%
Stock compensation expense	1.2			1.1			0.1			9.1	%
% of total sales	0.1		%	0.1		%
Total cost of sales	$	399.0		$	379.3		$	19.7		5.2	%
% of total sales	42.8		%	43.7		%
Gross profit	$	534.1		$	489.4		$	44.7		9.1	%
Gross profit percentage	57.2		%	56.3		%	0.9

The net increase in the dollar amount of cost of sales during the thirteen week period ended March 31, 2018 was primarily due to increased volume associated with the sales from acquisitions and organic sales growth for both commercial aftermarket and defense markets. This increase due to volume was slightly offset by a reduction in inventory purchase accounting adjustments as shown in the table above.

Gross profit as a percentage of sales increased by 0.9 percentage points to 57.2% for the thirteen week period ended March 31, 2018 from 56.3% for the thirteen week period ended April 1, 2017. The dollar amount of gross profit increased by $44.7 million, or 9.1%, for the quarter ended March 31, 2018 compared to the comparable quarter in the prior year due to the following items:


•	Gross profit on the sales from the acquisitions indicated above (excluding acquisition-related costs) was approximately $4.1 million for the quarter ended March 31, 2018, which represented gross profit of approximately 55.1% of the acquisition sales.

•

Organic sales growth as described above, 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) and positive leverage on our fixed overhead costs spread over a higher production volume resulted in a net increase in gross profit of approximately $39.5 million for the quarter ended March 31, 2018.

Table of Contents


•	Further increases in gross profit were due to lower inventory purchase accounting adjustments of $2.8 million partially offset by increases in acquisition integration costs of $1.6 million and stock compensation expense of $0.1 million for the quarter ended March 31, 2018.

•

Selling and Administrative Expenses. Selling and administrative expenses increased by $6.6 million to $107.5 million, or 11.5% of sales, for the thirteen week period ended March 31, 2018 from $100.9 million, or 11.6% of sales, for the thirteen week period ended April 1, 2017. Selling and administrative expenses and the related percentage of total sales for the thirteen week periods ended March 31, 2018 and April 1, 2017 were as follows (amounts in millions):



	Thirteen Week Periods Ended
	March 31, 2018			April 1, 2017			Change			% Change
Selling and administrative expenses - excluding costs below	$	95.2		$	87.0		$	8.2		9.4	%
% of total sales	10.2		%	10.0		%
Stock compensation expense	10.4			10.0			0.4			4.0	%
% of total sales	1.1		%	1.2		%
Acquisition-related expenses	1.9			3.9			(2.0		)	(51.3	)%
% of total sales	0.2		%	0.4		%
Total selling and administrative expenses	$	107.5		$	100.9		$	6.6		6.5	%
% of total sales	11.5		%	11.6		%

The increase in the dollar amount of selling and administrative expenses during the quarter ended March 31, 2018 is primarily due to higher selling and administrative expenses relating to recent acquisitions.

•

Amortization of Intangible Assets. Amortization of intangible assets was $17.5 million for the quarter ended March 31, 2018 compared to $22.0 million in the quarter ended April 1, 2017. The decrease in amortization expense of $4.5 million was due to the order backlog recorded in connection with the 2016 acquisitions becoming fully amortized in fiscal 2017. This was slightly offset by amortization expense on the definite-lived intangible assets (i.e., technology and order backlog) recorded in connection with the Third Quarter 2017 acquisitions.


•	Refinancing Costs. Refinancing costs of $0.6 million were recorded for the quarter ended March 31, 2018 which related to the debt refinancing activity described in Note 8, "Debt." Refinancing costs of $3.5 million were recorded for the quarter ended April 1, 2017 representing debt issuance costs expensed in connection with the debt financing activity during the first quarter of the previous year.

•

Interest Expense-net. Interest expense-net includes interest on borrowings outstanding, amortization of debt issuance costs, original issue discount and premium and revolving credit facility fees slightly offset by interest income. Interest expense-net increased $13.5 million, or 9.1%, to $161.3 million for the quarter ended March 31, 2018 from $147.8 million for the comparable quarter last year. The net increase in interest expense-net was primarily due to an increase in the weighted average level of outstanding borrowings, which was approximately $11,856 million for the quarter ended March 31, 2018 and approximately $11,206 million for the quarter ended April 1, 2017. The increase in weighted average level of borrowings was due to the additional 2025 Notes offering of $300 million in the second fiscal quarter of 2017, the additional $100 million drawn on the trade receivable securitization facility in the fourth quarter of fiscal 2017 and the additional net debt financing of $575 million in the fourth quarter of fiscal 2017. The weighted average interest rate for cash interest payments on total borrowings outstanding at March 31, 2018 was 5.2%.

•

Income Taxes. Income tax expense as a percentage of income before income taxes was approximately 18.3% for the quarter ended March 31, 2018 compared to 27.7% for the quarter ended April 1, 2017. The Company's lower effective tax rate for the thirteen week period ended March 31, 2018 was primarily due to reduction in U.S. federal corporate tax rate that was enacted in The Tax Cuts and Jobs Act which reduced the tax rate from 35% to 21%. As a result, the blended statutory tax rate for the year is 24.5%. Also contributing to the lower effective tax rate was the impact of excess tax benefits from share based payments

•

Loss from Discontinued Operations. On January 26, 2018, the Company completed the sale of Schroth in a management buyout to a private equity fund and certain members of Schroth management for approximately $61.4 million, subject to a working capital adjustment. The loss from discontinued operations was $5.6 million for the quarter ended March 31, 2018. Refer to Note 14, “Discontinued Operations,” for further information. The loss from discontinued operations was $0.2 million for the quarter ended April 1, 2017.


•	Net Income. Net income increased $40.8 million, or 26.2%, to $196.3 million for the quarter ended March 31, 2018 compared to net income of $155.5 million for the quarter ended April 1, 2017, primarily as a result of the factors referred to above.

Table of Contents


•	Earnings per Share. Basic and diluted earnings per share was $3.53 for the quarter ended March 31, 2018 and $2.78 per share for the quarter ended April 1, 2017.

	$	1,781.0	$	1,682.7	$	98.3	5.8	%

Organic defense and commercial aftermarket sales increased for the twenty-six week period ended March 31, 2018 compared to the twenty-six week period ended April 1, 2017 by $9.0 million and $70.5 million, or 1.6% and 12.2%, respectively. These increases were slightly offset by a decrease in organic commercial OEM sales of $7.4 million, or 1.6%.

Acquisition sales represent sales of acquired businesses for the period up to one year subsequent to their acquisition dates. The amount of acquisition sales shown in the table above was attributable to the Third Quarter 2017 Acquisitions described in Note 3, "Acquisitions and Divestitures."


•	Cost of Sales and Gross Profit. Cost of sales increased by $21.2 million, or 2.8%, to $770.3 million for the twenty-six week period ended March 31, 2018 compared to $749.1 million for the twenty-six week period ended April 1, 2017. Cost of sales and the related percentage of total sales for the twenty-six week periods ended March 31, 2018 and April 1, 2017 were as follows (amounts in millions):

Gross profit	$	1,010.7		$	933.7		$	77.0		8.2	%
Gross profit percentage	56.7		%	55.5		%	0.016

The net increase in the dollar amount of cost of sales during the twenty-six week period ended March 31, 2018 was primarily due to increased volume associated with the sales from acquisitions and organic commercial aftermarket sales growth. The increase due to volume was partially offset by lower inventory purchase accounting adjustments as shown in the table above.

Gross profit as a percentage of sales increased by 1.2 percentage points to 56.7% for the twenty-six week period ended March 31, 2018 from 55.5% for the twenty-six week period ended April 1, 2017. The dollar amount of gross profit increased by $77.0 million, or 8.2%, for the twenty-six week period ended March 31, 2018 compared to the comparable twenty-six week period in the prior year due to the following items:


•	Gross profit on the sales from the acquisitions indicated above (excluding acquisition-related costs) was approximately $10.3 million for the twenty-six week period ended March 31, 2018, which represented gross profit of approximately 59.0% of the acquisition sales.

•

Organic sales growth described above, 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) and positive leverage on our fixed overhead costs spread over a higher production volume resulted in a net increase in gross profit of approximately $49.5 million for the twenty-six week period ended March 31, 2018.

Table of Contents


•	Also contributing to the increase in gross profit were lower inventory purchase accounting adjustments of $19.4 million slightly offset by increases in acquisition integration costs of $2.0 million and stock compensation expense of $0.2 million charged to cost of sales for the twenty-six week period ended March 31, 2018.

•

Selling and Administrative Expenses. Selling and administrative expenses increased by $11.5 million to $214.1 million, or 12.0% of sales, for the twenty-six week period ended March 31, 2018 from $202.6 million, or 12.0% of sales, for the twenty-six week period ended April 1, 2017.

% of total sales	12.0		%	12.0		%

The increase in the dollar amount of selling and administrative expenses during the twenty-six week period ended March 31, 2018 is primarily due to higher selling and administration expenses related to recent acquisitions.

•

Amortization of Intangible Assets. Amortization of intangible assets was $34.6 million for the twenty-six week period ended March 31, 2018 compared to $47.6 million in the twenty-six week period ended April 1, 2017. The decrease in amortization expense of $13.0 million was primarily due to the order backlog recorded in connection with the 2016 acquisitions becoming fully amortized in fiscal 2017. This was slightly offset by amortization expense on the definite-lived intangible assets (i.e., technology and order backlog) recorded in connection with the Third Quarter 2017 acquisitions.

•

Refinancing Costs. Refinancing costs of $1.8 million were recorded for the twenty-six week period ended March 31, 2018, which related to the debt refinancing activity described in Note 8, "Debt." Refinancing costs of $35.6 million were recorded for the twenty-six week period ended April 1, 2017 representing debt issuance costs expensed in connection with the debt financing activity during the first and second quarter of the previous year, which primarily consisted of $28.8 million in premium paid on the redemption of the 2021 Notes and the write-off of $3.1 million in unamortized debt issuance costs, along with $3.3 million of debt issuance costs related to an additional issuance of our existing 2025 Notes.

•

Interest Expense-net. Interest expense-net includes interest on borrowings outstanding, amortization of debt issuance costs, original issue discount and premium and revolving credit facility fees slightly offset by interest income. Interest expense-net increased $28.4 million, or 9.6%, to $322.2 million for the twenty-six week period ended March 31, 2018 from $293.8 million for the comparable twenty-six week period last year. The net increase in interest expense-net was primarily due to an increase in the weighted average level of outstanding borrowings, which was approximately $11,864 million for the twenty-six week period ended March 31, 2018 and approximately $11,045 million for the twenty-six week period ended April 1, 2017. The increase in weighted average level of borrowings was primarily due to the additional 2025 Notes offering of $300 million in the end of the second fiscal quarter of 2017, the additional $100 million drawn on the trade receivable securitization facility in the fourth quarter of fiscal 2017, and the additional net debt financing of $575 million in the fourth quarter of fiscal 2017. The weighted average interest rate for cash interest payments on total borrowings outstanding at March 31, 2018 was 5.2%.

•

Income Taxes. Income tax expense as a percentage of income before income taxes was approximately (17.3)% for the twenty-six week period ended March 31, 2018 compared to 22.5% for the twenty-six week period ended April 1, 2017. The Tax Cuts and Jobs Act was enacted on December 22, 2017. The Act reduces the US federal corporate tax rate from 35% to 21%, requires companies to pay a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred and creates new taxes on certain foreign sourced earnings. The rate change is administratively effective at the beginning of our fiscal year, using a blended rate for the annual period. As a result, the blended statutory tax rate for the year is 24.5%. At March 31, 2018, we have not completed our accounting for the tax effects of enactment of the Act; however, in certain cases, we have made a reasonable estimate of the effects on our existing deferred tax balances and the one-time transition tax. We have recognized a provisional benefit amount of $170.2 million related to the remeasurement of our deferred tax balance for the twenty-six week period ended March 31, 2018. However, we are still analyzing certain aspects of the Act and refining our calculations, which could potentially affect the measurement of these balances or potentially give rise to new deferred tax amounts. In addition, we have recognized a provisional expense amount of $23.1 million for our one-time transition tax liability for the twenty-six week period ended March 31, 2018. The one-time transition tax is

Table of Contents

based on our total post-1986 E&P that we previously deferred from US income taxes and is based in part on the amount of those earnings held in cash and other specified assets. However, we continue to refine the calculation of the total post-1986 E&P for our foreign subsidiaries. This amount may change when we finalize the calculation of post-1986 foreign E&P previously deferred from US federal taxation and finalize the amounts held in cash or other specified assets. As a result of the Act, we recognized a provisional benefit amount of $147.1 million as a discrete tax benefit, which is included as a component of income tax expense from continuing operations. The Company's lower effective tax rate for the twenty-six week period ended March 31, 2018 was due to the reduction in the U.S. federal corporate tax rate as well as the discrete adjustment related to the enactment of the Act described above.

•

Loss from Discontinued Operations. On January 26, 2018, the Company completed the sale of Schroth in a management buyout to a private equity fund and certain members of Schroth management for approximately $61.4 million, subject to a working capital adjustment. The loss from discontinued operations was $2.8 million for the twenty-six week period ended March 31, 2018. Refer to Note 14, “Discontinued Operations,” for further details. The loss from discontinued operations was $0.2 million for the twenty-six week period ended April 1, 2017.


•	Net Income. Net income increased $236.7 million, or 86.3%, to $511.1 million for the twenty-six week period ended March 31, 2018 compared to net income of $274.4 million for the twenty-six week period ended April 1, 2017, primarily as a result of the factors referred to above.

•

Earnings per Share. Basic and diluted earnings per share was $8.18 for the twenty-six week period ended March 31, 2018 and $3.17 per share for the twenty-six week period ended April 1, 2017. For the twenty-six week period ended March 31, 2018, basic and diluted earnings per share from continuing operations and discontinued operations were $8.23 and $(0.05), respectively. Net income for the twenty-six week period ended March 31, 2018 of $513.9 million was decreased by dividend equivalent payments of $56.1 million, resulting in net income available to common shareholders of $454.9 million. Net income for the twenty-six week period ended April 1, 2017 of $274.4 million was decreased by an allocation of dividends on participating securities of $96.0 million, or $1.71 per share, resulting in net income available to common shareholders of $178.4 million.

Organic EBITDA As Defined increased approximately $66.7 million, or an increase of 15.0%, resulting from organic sales growth in commercial aftermarket sales, commercial OEM sales and defense sales, as well as the application of our three core value-driven operating strategies, and positive leverage on our fixed overhead costs spread over a higher production volume.

Organic EBITDA as Defined for the Airframe segment decreased $7.1 million, a 2.0% decrease, for the twenty-six week period ended March 31, 2018. Organic EBITDA As Defined decreased as a result of a decrease in commercial OEM sales and defense sales offset by organic sales growth in commercial aftermarket sales and the application of our three core value-driven operating strategies, and positive leverage on our fixed overhead costs spread over a higher production volume.

Backlog

As of March 31, 2018, the Company estimated its sales order backlog at $1,869 million compared to an estimated sales order backlog of $1,648 million as of April 1, 2017. The increase in backlog is primarily due to acquisitions and organic growth in both the defense market and the commercial aftermarket. The majority of the purchase orders outstanding as of March 31, 2018 are scheduled for delivery within the next twelve months. Purchase orders may be subject to cancellation or deferral by the customer prior to shipment. The level of unfilled purchase orders at any given date during the year will be materially affected by the timing of the Company’s receipt of purchase orders and the speed with which those orders are filled. Accordingly, the Company’s backlog as of March 31, 2018 may not necessarily represent the actual amount of shipments or sales for any future period.

Foreign Operations

Although we manufacture a significant portion of our products in the United States, we manufacture some products in Belgium, China, Germany, Hungary, Japan, Malaysia, Mexico, Norway, Sri Lanka, Sweden, and the United Kingdom. We sell our products in the United States as well as in foreign countries. Although the majority of sales of our products are made to customers (including distributors) located in the United States, our products are ultimately sold to and used by customers, including airlines and other end users of aircraft, throughout the world. A number of risks inherent in international operations could have a material adverse effect on our results of operations, including currency fluctuations, difficulties in staffing and managing multi-national operations, general economic and political uncertainties and potential for social unrest in countries in which we operate, limitations on our ability to enforce legal rights and remedies, restrictions on the repatriation of funds, change in trade policies, tariff regulation, difficulties in obtaining export and import licenses and the risk of government financed competition.

There can be no assurance that foreign governments will not adopt regulations or take other action that would have a direct or indirect adverse impact on the business or market opportunities of the Company within such governments’ countries. Furthermore, there can be no assurance that the political, cultural and economic climate outside the United States will be favorable to our operations and growth strategy.

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.

We continually evaluate our debt facilities to assess whether they most efficiently and effectively meet the current and future needs of our business. The Company evaluates from time to time the appropriateness of its current leverage, taking into consideration the Company’s debt holders, equity holders, credit ratings, acquisition opportunities and other factors.

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 additional 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.

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 more than 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 opportunistic investments in our own stock, make strategic business combinations and/or pay dividends to our shareholders.

Table of Contents

In the future, the Company may increase its borrowings in connection with acquisitions, if cash flows from operating activities becomes insufficient to fund current operations or for other short-term cash needs or for stock repurchases or special dividends. Our future leverage will also be impacted by the then current conditions of the credit markets.

Operating Activities. The Company generated $453.7 million of net cash from operating activities during the twenty-six week period ended March 31, 2018 compared to $390.5 million during the twenty-six week period ended April 1, 2017. The net increase of $63.2 million is primarily attributable to an increase in income from continuing operations of $69.3 million (excluding the non-cash effects of the adjustments resulting from the Tax Cuts and Jobs Act (approximately $170 million).

The change in accounts receivable during the twenty-six week period ended March 31, 2018 was a source of cash of $5.9 million compared to a source of cash of $3.1 million during the twenty-six week period ended April 1, 2017.

On August 22, 2017, the Company entered into Amendment No. 3 and Incremental Term Loan Assumption Agreement to the Second Amended and Restated Credit Agreement (“Amendment No. 3”). Pursuant to Amendment No. 3, TransDigm, among other things, incurred the new tranche G term loans in an aggregate principal amount equal to approximately $1.8 billion and repaid in full all of the tranche C term loans outstanding under the Restated Credit Agreement. The tranche G term loans were fully drawn on August 22, 2017. The tranche G term loans mature on August 22, 2024. The terms and conditions (other than maturity date) that apply to the tranche G term loans, including pricing, are substantially the same as the terms and conditions that applied to the tranche C term loans immediately prior to Amendment No. 3. Amendment No. 3 also permitted (a) payment of a special dividend, share repurchase, or combination thereof, in an aggregate amount up to approximately $1.3 billion within 60 days of the effective date of Amendment No. 3, and (b) certain additional restricted payments, including the ability of the Company to declare or pay dividends or repurchase stock, in an aggregate amount not to exceed $1.5 billion within twelve months of the effective date of Amendment No. 3 provided that, among other conditions, if such additional loans are to be used by the Company to repurchase shares of its capital stock, the consolidated secured net debt ratio would be no greater than 4.00 to 1.00 and if such additional terms loans are to be used by TD Group to pay dividends or other distributions on or in respect of its capital stock, the consolidated net leverage ratio would be no greater than 6.50 to 1.00, in each case, after giving effect to such incremental term loans. If any portion of the $1.5 billion is not used for dividends or share repurchases over such twelve month period, such amount (not to exceed $500 million) may be used to repurchase stock at any time thereafter.

On November 30, 2017, the Company entered into Amendment No. 4 to the Second Amended and Restated Credit Agreement (“Amendment No. 4”). Pursuant to Amendment No. 4, TransDigm, among other things, converted approximately $798.2 million of existing tranche D term loans into additional tranche F term loans and decreased the margin applicable to the existing tranche E term loans and tranche F term loans to LIBO rate plus 2.75% per annum and also removed the LIBO rate floor of 0.75%. The terms and conditions (other than maturity date) that apply to the tranche F term loans, including pricing, are substantially the same as the terms and conditions that apply to the tranche D term loans immediately prior to Amendment No. 4.

On February 22, 2018, the Company entered into a refinancing facility agreement to the Second Amended and Restated Credit Agreement. TransDigm, among other things, incurred new tranche G term loans in an aggregate principal amount equal to $1,809 million and repaid in full all of the existing tranche G term loans outstanding under the Second and Amended Restated Credit Agreement immediately prior to the refinancing facility agreement. The refinancing facility agreement also decreased the margin applicable to the tranche G term loans to LIBO rate plus 2.5% per annum. The terms and conditions that apply to the tranche G term loans, excluding pricing, are substantially the same as the terms and conditions that apply to the tranche G term loans immediately prior to the refinancing facility agreement.

Indentures



Senior Subordinated Notes	Aggregate Principal	Maturity Date	Interest Rate
2020 Notes	$550 million	October 15, 2020	5.50%
2022 Notes	$1,150 million	July 15, 2022	6.00%
2024 Notes	$1,200 million	July 15, 2024	6.50%
2025 Notes	$750 million	May 15, 2025	6.50%
2026 Notes	$950 million	June 15, 2026	6.375%

The 2020 Notes, the 2022 Notes, the 2024 Notes, and the 2026 Notes (the “Notes”) were issued at an issue price of 100% of the principal amount. The initial $450 million offering of the 2025 Notes (also considered to be part of the “Notes”) were issued at an issue price of 100% of the principal amount and the subsequent $300 million offering in the second quarter ended of fiscal 2017 of 2025 Notes were issued at an issue price of 101.5% of the principal amount, resulting in gross proceeds of $304.5 million.

Such Notes do not require principal payments prior to their maturity. Interest under the Notes is payable semi-annually. The Notes represent unsecured obligations of TransDigm Inc. ranking subordinate to TransDigm Inc.’s senior debt, as defined in the applicable Indentures.

The Notes are subordinated to all of TransDigm’s existing and future senior debt, rank equally with all of its existing and future senior subordinated debt and rank senior to all of its future debt that is expressly subordinated to the Notes. The Notes are guaranteed on a senior subordinated unsecured basis by TD Group and its wholly-owned domestic subsidiaries named in the indentures. The guarantees of the 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 Notes. The Notes are structurally subordinated to all of the liabilities of TD Group’s non-guarantor subsidiaries. The Notes

Table of Contents

contain many of the restrictive covenants included in the Credit Agreement. TransDigm is in compliance with all of the covenants contained in the Notes.

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. 3. The restrictive covenants are described above in the Recent Amendments to the Credit Agreement section.

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 7.25 to 1.00 and the consolidated secured net debt ratio would be no greater than 4.25 to 1.00, in each case, after giving effect to such incremental term loans or additional revolving commitments.

The Credit Agreement requires mandatory prepayments of principal based on certain percentages of Excess Cash Flow (as defined in the Credit Agreement), commencing 90 days after the end of each fiscal year, subject to certain exceptions. In addition, subject to certain exceptions (including, with respect to asset sales, the reinvestment in productive assets), TransDigm will be required to prepay the loans outstanding under the Credit Agreement at 100% of the principal amount thereof, plus accrued and unpaid interest, with the net cash proceeds of certain asset sales and issuance or incurrence of certain indebtedness. No matters mandating prepayments occurred during the quarter ended March 31, 2018.

In addition, under the Credit Agreement, if the usage of the revolving credit facility exceeds 25% of the total revolving commitments, the Company will be required to maintain a maximum consolidated net leverage ratio of net debt, as defined, to trailing four-quarter EBITDA As Defined. A breach of any of the covenants or an inability to comply with the required leverage ratio could result in a default under the Credit Agreement or the Indentures.

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.

As of March 31, 2018, the Company was in compliance with all of its debt covenants.

Trade Receivables Securitization

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. In August 2017, the Company amended the Securitization Facility to increase the borrowing capacity to $300 million and extend the maturity date to August 1, 2018. As of March 31, 2018, the Company has borrowed $300 million under the Securitization Facility. The Securitization Facility is collateralized by substantially all of the Company’s domestic operations’ trade accounts receivable.

Stock Repurchase Program

On November 8, 2017, our Board of Directors, authorized a new stock repurchase program replacing the previous $600 million program and 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 quarter and year-to-date period ended March 31, 2018.

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 accounting principles generally accepted in the United States of America (“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 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 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 GAAP, and neither should be considered as an alternative to net income or cash flow from operations determined in accordance with GAAP. Our calculation of EBITDA and EBITDA As Defined may not be comparable to the calculation of similarly titled measures reported by other companies.

During the fourth quarter of 2017, the Company committed to disposing of Schroth in connection with the settlement of a Department of Justice investigation into the competitive effects of the acquisition. Therefore, Schroth was classified as held-for-sale beginning September 30, 2017. On January 26, 2018, the Company completed the sale of Schroth in a management buyout to a private equity fund and certain members of Schroth management for approximately $61.4 million, subject to a working capital adjustment.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

The information called for by this item is provided under the caption 'Description of Senior Secured Credit Facilities and Indentures' under Item 2 - "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. These market risks have not materially changed since the date our most recent Form 10-K was filed with the SEC.

ITEM 4. CONTROLS AND PROCEDURES

As of March 31, 2018, TD Group carried out an evaluation, under the supervision and with the participation of TD Group’s management, including its President and Chief Executive Officer (Principal Executive Officer) and Executive Vice President and Interim Chief Financial Officer (Principal Financial and Accounting Officer), of the effectiveness of the design and operation of TD Group’s disclosure controls and procedures. Based upon that evaluation, the President and Chief Executive Officer and Executive Vice President and Interim 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 Securities Exchange Act of 1934, as amended, 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 President and Chief Executive Officer and Executive Vice President and Interim 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. There have been no significant changes in TD Group’s internal controls or other factors that could significantly affect the internal controls subsequent to the date of TD Group’s evaluations.

Changes in Internal Control over Financial Reporting

There was no change in the Company’s internal control over financial reporting that occurred during the fiscal quarter ended March 31, 2018, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting. During the fiscal quarter ending March 31, 2018 and year-ended September 30, 2017, the Company completed the acquisition of Kirkhill and the Third Quarter 2017 Acquisitions. The Company is currently integrating these acquisitions into its operations, compliance programs and internal control processes. As permitted by SEC rules and regulations, the Company has excluded these acquisitions from management's evaluation of internal controls over financial reporting as of March 31, 2018. These acquisitions constituted less than 2% of the Company's total assets as of March 31, 2018, and less than 1% of the Company's net sales in the fiscal quarter ended March 31, 2018.

PART II: OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

We and certain of our current or former officers and directors are defendants in a consolidated securities class action captioned In re TransDigm Group, Inc. Securities Litigation, Case No. 1:17-cv-01677-DCN (N.D. Ohio). The cases were originally filed on August 10, 2017, and September 18, 2017 and were consolidated on December 5, 2017. A consolidated amended complaint was filed on February 16, 2018. The plaintiffs allege that the defendants made false or misleading statements with respect to, or failed to disclose, the impact of certain alleged business practices in connection with sales to the U.S. government on the Company’s growth and profitability. The plaintiffs assert claims under Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder and Section 20(a) of the Exchange Act, and seek unspecified monetary damages and other relief. In addition, we, as nominal defendant, and certain of our current or former officers and directors are defendants in a shareholder derivative action captioned Sciabacucchi v. Howley et al., No. 1:17-cv-1971-DCN (N.D. Ohio). The case was filed on September 19, 2017. The plaintiffs allege breach of fiduciary duty and other claims arising out of substantially the same actions or inactions alleged in the securities class actions described above. This action has been stayed pending the outcome of an anticipated motion to dismiss on the securities class action. Although we are only a nominal defendant in the derivative action, we could have indemnification obligations and/or be required to advance the costs and expenses of the officer and director defendants in the action.

We intend to vigorously defend these matters and believe they are without merit. We also believe we have sufficient insurance coverage available for these matters. Therefore, we do not expect these matters to have a material adverse impact on our financial condition or results of operations. However, given the preliminary status of the litigation, it is difficult to predict the likelihood of an adverse outcome or estimate a range of any potential loss.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, you should carefully consider the risk factors disclosed in Item 1A of our Annual Report on Form 10-K for the fiscal year ended September 30, 2017, filed on November 13, 2017. There have been no material changes to the risk factors set forth therein.

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

On November 8, 2017, our Board of Directors, authorized a new stock repurchase program replacing the previous $600 million program and 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 thirteen and twenty-six week periods ended March 31, 2018.
