Item 7.01. Regulation FD Disclosure.

On May 1, 2018, TransDigm Group Incorporated (“TransDigm Group”) issued a press release (the “Launch Press Release”) relating to the proposed offering of $500 million aggregate principal amount of senior subordinated notes due 2026 (the “Notes”) by TransDigm UK Holdings plc, its wholly-owned subsidiary (the “Company”), 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 Launch Press Release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

In the Offering Memorandum, the TransDigm Group discloses that it expects to (i) incur $700 million in additional tranche E term loans, (ii) reprice its existing tranche E term loans and tranche F term loans and (iii) extend its existing revolving credit facility to December 2022 (collectively, the “2018 Credit Facility Transactions”), in each case from existing and new lenders under the senior secured credit facilities. In connection with the 2018 Credit Facility Transactions, TransDigm Group may also make certain other modifications to the terms of the senior secured credit facilities.

In the Offering Memorandum, the TransDigm Group discloses pro forma net sales and pro forma EBITDA As Defined of $3,621.9 million and $1,767.0 million, respectively, for the twelve months ended December 30, 2017. These amounts reflect the TransDigm Group’s estimates that if certain transactions, including the Extant Acquisition (as defined below), had closed at the beginning of that period, the transactions would have contributed additional net sales and EBITDA As Defined of approximately $83.7 million and $36.1 million, respectively, for the twelve-month period ended December 30, 2017. Due to the unique nature of the TransDigm Group’s previously announced acquisition of the Kirkhill elastomer business (“Kirkhill”), which the TransDigm Group purchased as a distressed asset in March 2018, management is currently unable to estimate the impact Kirkhill would have had on the Company’s EBITDA As Defined for the last twelve months ended December 30, 2017. While management believes that Kirkhill’s EBITDA as a standalone business may have been negative for the last twelve months ended December 30, 2017, any such loss would have been immaterial to the Company on a consolidated basis. Once Kirkhill is fully integrated into the Company’s business model, management believes that it will be a positive contributor to the Company’s EDITDA As Defined. The reconciliation of net income to EBITDA, EBITDA As Defined and Pro Forma EBITDA As Defined is furnished as Exhibit 99.2 to this Current Report on Form 8-K.

In the Offering Memorandum, the Company discloses that the TransDigm Group and certain of its 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 TransDigm Group’s growth and profitability. The plaintiffs assert claims under Section 10(b) of the Securities Exchange Act of 1934 (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, the TransDigm Group, as nominal defendant, and certain of its current or former officers and directors are defendants in a shareholder derivative action captioned Sciabacucchi v. Howley et al., Civil Action No. 1:17-cv-1971 (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 action described above. This action has been stayed pending the outcome of an anticipated motion to dismiss on the securities class action. Although the TransDigm Group is only a nominal defendant in the derivative action, it could have indemnification obligations and/or be required to advance the costs and expenses of the officer and director defendants in the action. The TransDigm Group intends to vigorously defend these matters and believes they are without merit. The TransDigm Group also believes it has sufficient insurance coverage available for these matters. Therefore, the TransDigm Group does not expect these matters to have a material adverse impact on its 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.

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 Launch 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 intends to use the net proceeds from the offering of the Notes and the 2018 Credit Facility Transactions to replenish the cash used to fund the purchase price for its acquisitions of the Kirkhill elastomers business and Extant Components Group Holding, Inc. This cash and the remainder of the net proceeds with be used for general corporate purposes, including potential future acquisitions, dividends or repurchases under its stock repurchase program.

The information in this Item 7.01 to Current Report on Form 8-K and in the Launch Press Release shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, nor shall it be deemed incorporated by reference in filings under the Securities Act.

Item 8.01. Other Events.

On May 1, 2018, TransDigm Group issued a press release announcing its financial results for the three-month period ended March 31, 2018 (the “Earnings Press Release”). Certain financial information (collectively, the “Financial Information”), included as part of the Earnings Press Release, is filed as Exhibit 99.3 to this report.

Exhibit 99.2

Reconciliation of Net Income to EBITDA, EBITDA As Defined and Pro Forma EBITDA As Defined

EBITDA represents earnings from continuing operations before interest, taxes, depreciation and amortization. EBITDA As Defined represents EBITDA plus, as applicable for each relevant period, certain adjustments as set forth in the reconciliation of net income to EBITDA and EBITDA As Defined and the reconciliation of net cash provided by operating activities to EBITDA and EBITDA As Defined presented below. Pro Forma EBITDA As Defined (for the last twelve months ended December 30, 2017) represents EBITDA As Defined plus management’s estimates of the impact of the acquisition of North Hills Signal Processing Corp. and North Hills Signal Processing Overseas Corp. (together, “North Hills”), the acquisition of certain assets of Cablecraft Motion Controls LLC (“Cablecraft”), the acquisition of certain assets of Preece Incorporated (“Preece”) and the acquisition of Extant Components Group Holdings, Inc. (“Extant”) had such transactions occurred at the beginning of the twelve-month period ended December 30, 2017. Due to the unique nature of our acquisition of the Kirkhill elastomers business (“Kirkhill”), which we purchased as a distressed asset in March 2018, our management is currently unable to estimate the impact Kirkhill would have had on our EBITDA As Defined for the last twelve months ended December 30, 2017. While we believe that Kirkhill’s EBITDA as a standalone business may have been negative for the last twelve months ended December 30, 2017, any such loss would have been immaterial to us on a consolidated basis and we believe that, once Kirkhill is fully integrated into our business model, that it will be a positive contributor to our EDITDA As Defined.

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

EX-99.3

Exhibit 99.3

TransDigm Group Incorporated (NYSE: TDG) (“TD Group” or the “Company”), a leading global designer, producer and supplier of highly engineered aircraft components, today reported results for the second quarter ended March 31, 2018.

Second Quarter Results

Net sales for the quarter rose 7.4%, or $64.4 million, to $933.1 million from $868.7 million in the comparable quarter a year ago. Organic sales growth was 6.6%.

Net income from continuing operations for the quarter rose 29.6% to $201.8 million, or $3.63 per share, compared to $155.7 million, or $2.78 per share, in the comparable quarter a year ago. The current quarter was positively impacted by a lower effective tax rate due to the U.S. Tax Cuts and Jobs Act (tax reform) of 18.3% compared to 27.7% in the second quarter of 2017. The balance of the increase in net income primarily reflects the increase in net sales described above and improvements to our operating margin resulting from the strength of our proprietary products and continued productivity efforts. This growth in net income was partially offset by higher interest expense.

Net loss from discontinued operations in the quarter was $5.6 million, or $0.10 loss per share attributable to the sale of Schroth.

Adjusted net income for the quarter rose 24.5% to $210.8 million, or $3.79 per share, from $169.3 million, or $3.03 per share, in the comparable quarter a year ago. Adjusted earnings per share in the current fiscal year includes $0.41 of favorable impact from the enactment of tax reform. Excluding this favorable tax impact, current earnings per share of $3.38 increased 11.6% over the prior year.

EBITDA for the quarter increased 10.5% to $439.4 million from $397.7 million for the comparable quarter a year ago. EBITDA As Defined for the period increased 9.8% to $463.1 million compared with $421.7 million in the comparable quarter a year ago. EBITDA As Defined as a percentage of net sales for the quarter was 49.6%.

Year-to-Date Results

Net sales for the twenty-six week period ended March 31, 2018 rose 5.8% to $1,781.0 million from $1,682.7 million in the comparable period last year. Organic net sales growth was 4.8%.

Net income from continuing operations for the twenty-six week period ended March 31, 2018 increased 87.2% to $513.9 million, or $8.23 per share, compared with $274.6 million, or $3.17 per share, in the comparable period last year. The current twenty-six week period was positively impacted by a lower effective tax rate due to tax reform. The current effective tax rate was a benefit of 17.3% compared to a provision of 22.5% for the first half of fiscal 2017. The balance of the increase in net income primarily reflects growth in net sales described above, lower refinancing costs and lower acquisition-related costs, as well as improvements to our operating margin resulting from the strength of our proprietary products and continued productivity efforts. This growth in net income was partially offset by higher interest expense due to an increase in the level of outstanding borrowings to $11.8 billion from $11.2 billion outstanding in the comparable period last year.

1

Earnings per share were reduced in both 2018 and 2017 by $1.01 per share and $1.71 per share, respectively, representing dividend equivalent payments made during each year.

Net loss from discontinued operations in the twenty-six week period ended March 31, 2018 was $2.8 million, or $0.05 loss per share.

Adjusted net income for the twenty-six week period ended March 31, 2018 rose 66.9% to $520.9 million, or $9.37 per share, from $312.0 million, or $5.55 per share, in the comparable period a year ago. Adjusted earnings per share in the current fiscal year includes $3.37 of favorable impact from the enactment of tax reform. Excluding this favorable tax impact, current earnings per share of $6.00 increased 8.1% over the prior year.

EBITDA for the twenty-six week period ended March 31, 2018 increased 14.1% to $822.0 million from $720.7 million for the comparable period a year ago. EBITDA As Defined for the period increased 7.7% to $864.7 million compared with $802.9 million in the comparable period a year ago. EBITDA As Defined as a percentage of net sales for the period was 48.5%.

Please see the below tables for a reconciliation of net income to EBITDA, EBITDA As Defined, and adjusted net income; a reconciliation of net cash provided by operating activities to EBITDA and EBITDA As Defined, and a reconciliation of earnings per share to adjusted earnings per share for the periods discussed in this press release.

Non-GAAP Supplemental Information

EBITDA, EBITDA As Defined, EBITDA As Defined Margin, adjusted net income and adjusted earnings per share are non-GAAP financial measures presented in this press release as supplemental disclosures to net income and reported results. TD Group defines EBITDA as earnings before interest, taxes, depreciation and amortization and defines 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. TD Group defines adjusted net income as net income plus purchase accounting backlog amortization expense, effects from the sale on businesses, refinancing costs, acquisition-related costs, transaction-related costs and non-cash charges incurred in connection with certain employee benefit plans. EBITDA As Defined Margin represents EBITDA As Defined as a percentage of net sales. TD Group defines adjusted diluted earnings per share as adjusted net income divided by the total shares for basic and diluted earnings per share. For more information regarding the computation of EBITDA, EBITDA As Defined and adjusted net income and adjusted earnings per share, please see the attached financial tables.

2

TD Group presents these non-GAAP financial measures because it believes that they are useful indicators of its operating performance. TD Group believes that EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties to measure operating performance among companies with different 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. In addition, analysts, rating agencies and others use EBITDA to evaluate a company’s ability to incur and service debt. EBITDA As Defined is used to measure TransDigm Inc.’s compliance with the financial covenant contained in its credit facility. TD Group’s management also uses EBITDA As Defined to review and assess its operating performance, to prepare its annual budget and financial projections and to review and evaluate its management team in connection with employee incentive programs. Moreover, TD Group’s management uses EBITDA As Defined to evaluate acquisitions and as a liquidity measure. In addition, TD Group’s management uses adjusted net income as a measure of comparable operating performance between time periods and among companies as it is reflective of changes in pricing decisions, cost controls and other factors that affect operating performance.

None of EBITDA, EBITDA As Defined, EBITDA As Defined Margin, adjusted net income or adjusted earnings per share is a measurement of financial performance under GAAP and such financial measures should not be considered as an alternative to net income, operating income, earnings per share, cash flows from operating activities or other measures of performance determined in accordance with GAAP. In addition, TD Group’s calculation of these non-GAAP financial measures may not be comparable to the calculation of similarly titled measures reported by other companies.

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.
