TransDigm Group Incorporated (“TransDigm Group”), which includes, for purposes of this Item 2.02, its direct and indirect subsidiaries, is hereby furnishing the following information regarding its business, which has not been previously reported, in connection with the concurrent offerings of the Notes (as defined below), as discussed in Item 7.01 of this Current Report on Form 8-K.

TransDigm Group has not yet finalized its financial results for the thirteen-week period or fiscal year ended September 30, 2019. However, based on its unaudited preliminary analysis, it estimates that it will have the following selected results for the thirteen-week period ended September 30, 2019:

In addition, based on its unaudited preliminary analysis, it estimates that it will have the following selected results for the fiscal year ended September 30, 2019:

The thirteen-week period and full fiscal year periods ended September 30, 2019 reflect the financial results of the previously announced divestures of the Esterline Interface Technology group of businesses and the Souriau-Sunbank Connection Technologies business as discontinued operations. As such, $297 million of revenue and $63 million of EBITDA as Defined has been excluded and will be reported as discontinued operations for the full fiscal year period ended September 30, 2019.

TransDigm Group’s preliminary results for the thirteen-week period and fiscal year ended September 30, 2019 are preliminary, unaudited and represent the most current information available to TransDigm Group’s management. TransDigm Group’s actual results may differ from the preliminary results due to the completion of its financial closing procedures, final adjustments and other developments that may arise between the date of this Current Report on Form 8-K and the time that financial results for the thirteen-week period and fiscal year ended September 30, 2019 are finalized.

The preliminary results included herein have been prepared by, and are the responsibility of, TransDigm Group’s management. Ernst & Young LLP, TransDigm Group’s independent registered public accounting firm, has not audited, reviewed, compiled, or performed any procedures with respect to the preliminary financial results. Accordingly, Ernst & Young LLP does not express an opinion or any other form of assurance with respect thereto.

The following sets forth a reconciliation of net income to EBITDA and EBITDA As Defined:

The following sets forth a reconciliation of the mid-point of our estimated range of income from continuing operations to EBITDA and EBITDA As Defined:

On October 29, 2019, TransDigm Group issued a press release (the “Press Release”) relating to the proposed offering of senior subordinated notes (the “Notes”) by TransDigm Inc., its wholly-owned subsidiary, pursuant to a confidential offering memorandum (the “Offering Memorandum”) in a private placement under Rule 144A and Regulation S of the Securities Act of 1933 (the “Securities Act”). A copy of the Press Release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

In the Offering Memorandum, TransDigm Group discloses net sales and EBITDA As Defined of $4,847 million and $2,274 million, respectively, for the twelve-month period ended June 29, 2019. Had the acquisition of

Esterline Technologies Corporation (“Esterline”) closed at the beginning of that period, based on management’s estimates, the transactions would have contributed additional net sales and EBITDA As Defined of approximately $1,417 million and $229 million, respectively, for the twelve-month period ended June 29, 2019. The reconciliation of net income to EBITDA, EBITDA As Defined and Pro Forma EBITDA As Defined for the twelve-month period ended June 29, 2019 is furnished as Exhibit 99.2 to this Current Report on Form 8-K.

The Notes will not be registered under the Securities Act or any state securities laws and may not be offered or sold in the United States without registration or an applicable exemption from the registration requirements of the Securities Act and applicable state securities laws. Neither the Press Release nor this Current Report on Form 8-K constitutes an offer to sell or the solicitation of an offer to buy the Notes, nor shall there be any sale of the Notes in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such state.

TransDigm Group expects to use a portion of the net proceeds of this offering to redeem all of its outstanding 6.000% Senior Subordinated Notes due 2022 (the “2022 notes”). The remaining net proceeds will be used for general corporate purposes, which may include potential future acquisitions, dividends or repurchases under our stock repurchase program.

The information in this Current Report on Form 8-K and in the Press Release shall not be deemed “filed” for purposes of Section 18 of the Exchange Act of 1934 (the “Exchange Act”), nor shall it be deemed incorporated by reference in filings under the Securities Act.

Non-GAAP Financial Measures

This Current Report on Form 8-K contains non-GAAP financial measures such as EBITDA, EBITDA As Defined and Pro Forma EBITDA As Defined, none of which are measurements of financial performance under generally accepted accounting principles in the United States (“GAAP”). TransDigm Group defines “EBITDA” as earnings before interest, taxes, depreciation and amortization, “EBITDA As Defined” as EBITDA plus certain non-operating items, refinancing costs, acquisition-related costs, transaction-related costs and non-cash charges incurred in connection with certain employee benefit plans and “Pro Forma EBITDA As Defined” as EBITDA As Defined plus management’s estimates of the impact of the acquisition of Esterline as if such acquisition occurred at the beginning of the twelve-month period ended June 29, 2019. TransDigm Group presents EBITDA, EBITDA As Defined and Pro Forma EBITDA As Defined because it believes they are useful indicators for evaluating operating performance and liquidity.

TransDigm Group’s management believes that EBITDA, EBITDA As Defined and Pro Forma EBITDA As Defined are useful to investors because they are frequently used by securities analysts, investors and others to measure operating performance among companies with differing capital structures, effective tax rates and tax attributes, capitalized asset values and employee compensation structures, all of which can vary substantially from company to company depending upon, among other things, accounting methods, book value of assets and the method by which assets are acquired. These measures are useful to evaluate TransDigm Group’s business between time periods without regard to items such as interest expense, income tax expense and depreciation and amortization. TransDigm Group also believes EBITDA is useful to investors as a measure of comparative operating performance among companies and between time periods as it is reflective of changes in pricing decisions, cost controls and other factors that affect operating performance.

TransDigm Group’s management also believes that EBITDA, EBITDA As Defined and Pro Forma 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 TransDigm Group’s senior secured credit facilities requires compliance under certain circumstances, on a pro forma basis, with a financial covenant that measures the ratio of the amount of TransDigm Group’s total net indebtedness to the amount of its Consolidated EBITDA, defined in substantially the same manner as it defines EBITDA As Defined herein. This financial covenant is a material term of the revolving credit facility under TransDigm Group’s senior secured credit facilities as the failure to comply with such financial covenant could result in an event of default in respect of its senior secured credit facilities (and such an event of default could, in turn, result in an event of default under the indentures governing its notes).

In addition to the above, TransDigm Group’s 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, TransDigm Group’s management uses EBITDA As Defined to evaluate acquisitions.

Although TransDigm Group uses EBITDA, EBITDA As Defined and Pro Forma EBITDA As Defined as measures to assess the performance of its 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 TransDigm Group’s results of operations as reported in accordance with GAAP. Some of these limitations are:

Because of these limitations, EBITDA, EBITDA As Defined and Pro Forma EBITDA As Defined should not be considered as measures of discretionary cash available to TransDigm Group to invest in the growth of its business. Management compensates for these limitations by not viewing EBITDA, EBITDA As Defined or Pro Forma EBITDA As Defined in isolation and specifically by using other GAAP measures, such as net income, net sales and operating profit, to measure TransDigm Group’s operating performance. None of EBITDA, EBITDA As Defined or Pro Forma EBITDA As Defined is a measurement of financial performance under GAAP, and none should be considered as an alternative to net income or cash flow from operations determined in accordance with GAAP. TransDigm Group’s calculation of EBITDA, EBITDA As Defined and Pro Forma EBITDA As Defined may not be comparable to the calculation of similarly titled measures reported by other companies.
