July 31, 2006 at 12:00 AM EDT

CLEVELAND, July 31, 2006 - TransDigm Group Incorporated (NYSE: TDG), a leading global designer, producer and supplier of highly engineered aircraft components, today reported results for the fiscal 2006 third quarter and thirty-nine weeks ended July 1, 2006.

Net sales for the quarter increased 13.6% to $110.9 million from $97.6 million in the comparable quarter a year ago. Net loss for the quarter was $13.4 million, or $0.30 per diluted share, compared to net income of $9.5 million, or $0.21 per diluted share, in the comparable quarter a year ago. Adjusted net income increased 46.8% for the quarter to $16.5 million, or $0.35 per diluted share, from $11.2 million, or $0.24 per diluted share, in the same quarter a year ago. Adjusted net income for the current quarter excludes $29.1 million net of tax, or $0.62 per diluted share, of costs related to the June 2006 debt refinancing and $0.8 million net of tax, or $0.02 per diluted share, of other non-cash compensation, non-recurring IPO costs and acquisition related expenses. Adjusted net income for the prior year quarter excludes $1.7 million net of tax, or $0.03 per diluted share, of non-cash compensation and acquisition related expenses. EBITDA for the quarter was $(0.5) million versus $40.1 million for the comparable quarter a year ago. EBITDA As Defined increased 15.0% for the quarter to $49.3 million versus $42.9 million for the comparable quarter a year ago.

Year-to-Date Results

Year-to-date net sales were $319.3 million, an 18.6% increase over net sales of $269.3 million in the comparable period last year. Year-to-date net income declined 59.9% to $9.9 million, or $0.21 per diluted share, from $24.7 million, or $0.53 per diluted share, in the comparable period a year ago. Adjusted net income increased 53.2% for the period to $44.5 million, or $0.94 per diluted share, from $29.0 million, or $0.63 per diluted share, in the same period a year ago. Adjusted net income in the current year-to-date period excludes $29.1 million net of tax, or $0.62 per diluted share, of costs related to the June 2006 debt refinancing and $5.5 million, or $0.11 per diluted share, of initial public offering expenses, certain non-cash compensation related expenses, a one-time special bonus and acquisition related expenses. Adjusted net income in the prior year-to-date period excludes $4.4 million, or $0.09 per diluted share, of certain non-cash compensation related expenses and acquisition related expenses. Year-to-date EBITDA was $84.6 million versus $111.2 million for the comparable period a year ago. EBITDA As Defined for the period increased 20.3% to $142.2 million versus $118.2 million for the comparable period a year ago.

As previously announced, during the quarter TransDigm completed the acquisitions of Sweeney Engineering Corp. and Electra-Motion Industries Inc. in unrelated transactions for a combined purchase price of approximately $27 million. Both businesses are located in the Southern California area and have been suppliers of proprietary, highly engineered components to the aerospace and defense industries for many years.

The previously announced debt refinancing included the issuance and sale of $275 million in aggregate principal amount of 7 3/4% Senior Subordinated Notes due 2014 and the borrowing of an aggregate of $650 million under a new senior secured credit facility. The proceeds from these transactions, together with a portion of TransDigm's available cash balances, were used to repay TransDigm Inc.'s former secured credit facility and TransDigm Group's unsecured loan facility and to purchase substantially all of TransDigm Inc.'s 8 3/8% Senior Subordinated Notes due 2011.

"We are pleased with our operating results for both the third quarter and the year-to-date period," stated W. Nicholas Howley, TransDigm's Chairman and CEO. "We continued to see strong organic growth in our commercial aerospace OEM market. Our commercial aerospace aftermarket continues to be up significantly on a year-to-date basis, though third quarter results were slightly impacted by the timing of shipments between the second and third quarters. Our defense shipments continue to be down modestly on a year-to- date basis but have increased for two consecutive quarters. We are particularly pleased with our 18.6% increase in year-to-date revenues and 20.3% increase in year-to-date EBITDA As Defined. The revenue growth was made up of approximately 12% organic growth and 6.6% from acquisitions. The EBITDA As Defined growth is even more heavily weighted toward organic growth."

"In addition to strong operating results in our third quarter, we were able to both acquire two proprietary aerospace component businesses that fit well with our existing products and also complete a restructuring of our debt to allow both a lower overall interest rate and greater flexibility," said Mr. Howley.

Revision to Future Expectations

Looking ahead, Mr. Howley stated, "We remain optimistic for the balance of fiscal 2006. Based on current market conditions, our strong third quarter, the two recent acquisitions and the completion of our debt refinancing, we feel comfortable increasing our full year guidance. TransDigm Group now expects revenues for fiscal year 2006 to be approximately $435 million; EBITDA As Defined to be approximately $192 million; adjusted earnings per diluted share to be in the range of $1.28 to $1.30 per share; and reported earnings per diluted share to in the range of $0.53 to $0.55. Approximately $.025 per share of the forecasted adjusted earnings per diluted share is due to the recent acquisitions in fiscal 2006 and debt restructuring."

Non-GAAP Supplemental Information

EBITDA, EBITDA As Defined, 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. TransDigm Group defines EBITDA as earnings before interest, taxes, depreciation and amortization and defines EBITDA As Defined as EBITDA plus certain non- operating items and certain non-recurring acquisition costs. TransDigm Group defines adjusted net income as net income plus certain non-operating items, certain non-recurring acquisition costs and certain non-recurring expenses incurred in connection with the refinancing and its initial public offering. For more information regarding the nature of these non-operating items, non- recurring acquisition costs and non-recurring expenses, please see the attached financial tables.

TransDigm Group presents these non-GAAP financial measures because it believes that they are a useful indicator of its operating performance. TransDigm Group believes that EBITDA is useful to investors because it is frequently used by securities analysts, investors and other interested parties to measure a company's operating performance without regard to items such as interest expense, income tax expense and depreciation and amortization, which can vary substantially from company to company. EBITDA As Defined is used to measure TransDigm Inc.'s compliance with the financial covenants contained in its credit facility. TransDigm Group's management also uses EBITDA As Defined to review and assess the company's operating performance and management team in connection with employee incentive programs and the preparation of the company's annual budget and financial projections. In addition, TransDigm Group's management and our investors use 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, 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, cash flows from operating activities or other measures of performance determined in accordance with GAAP. In addition, TransDigm Group's calculation of these non-GAAP financial measures may not be comparable to the calculation of similarly titled measures reported by other companies.
