Forward-looking Statements

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

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

Important factors that could cause actual results to differ materially from the forward-looking statements made in this Quarterly Report on Form 10-Q include but are not limited to: the sensitivity of our business to the number of flight hours that our customers’ planes spend aloft and our customers’ profitability, both of which are affected by general economic conditions; supply chain constraints; increases in raw material costs, taxes and labor costs that cannot be recovered in product pricing; failure to complete or successfully integrate acquisitions; our indebtedness; current and future geopolitical or other worldwide events, including, without limitation, wars or conflicts and public health crises; cybersecurity threats; risks related to the transition or physical impacts of climate change and other natural disasters or meeting regulatory requirements; our reliance on certain customers; the United States (“U.S.”) defense budget and risks associated with being a government supplier including government audits and investigations; failure to maintain government or industry approvals; risks related to changes in laws and regulations, including increases in compliance costs and potential changes in trade policies and tariffs; potential environmental liabilities; liabilities arising in connection with litigation; risks and costs associated with our international sales and operations; and other factors. Refer to Part II, Item 1A included in this Quarterly Report on Form 10-Q and to Part I, Item 1A of the Annual Report on Form 10-K for additional information regarding the foregoing factors that may affect our business.

Overview

We believe we are a leading global designer, producer and supplier of highly engineered proprietary aerospace components with significant aftermarket content. We seek to develop highly customized products to solve specific needs for aircraft operators and manufacturers. We attempt to differentiate ourselves based on engineering, service and manufacturing capabilities. We believe that our products have strong brand names within the industry and that we have a reputation for high quality, reliability and strong customer support. We believe we have achieved steady, long-term growth in sales and improvements in operating performance due to our competitive strengths and through execution of our value-driven operating strategy. More specifically, focusing our businesses on our value-driven operating strategy of obtaining profitable new business, carefully controlling the cost structure via productivity and cost improvements and pricing our highly engineered value-added products to fairly reflect the value we provide and the resources required to do so has historically resulted in improvements in gross profit and income from operations over the long-term.

Our selective acquisition strategy has also been an important contribution to the growth of our business. We maintain a selective acquisition strategy, concentrating on proprietary commercial aerospace component businesses with significant aftermarket content where we see a clear path to value creation through the application of our three core value drivers. The integration of acquisitions into our existing businesses combined with implementing our proven operating strategy has historically resulted in improvements in the financial performance of the acquired businesses.

For the first quarter of fiscal 2026, we generated net sales of $2,285 million and net income attributable to TD Group of $445 million. EBITDA As Defined was $1,197 million, or 52.4% of net sales. Refer to the “Non-GAAP Financial Measures” section for certain information regarding EBITDA and EBITDA As Defined, including reconciliations of EBITDA and EBITDA As Defined to net income and net cash provided by operating activities.

For the thirteen week period ended December 27, 2025, demand for air travel remained strong both domestically and internationally. Commercial aftermarket sales increased in the first quarter of fiscal 2026 compared to fiscal 2025 primarily due to the overall demand for air travel, particularly international air traffic growth, which has outpaced domestic growth. Passenger load factors remain strong and have reached record levels in recent months in certain markets.

Our commercial transport original equipment manufacturer (“OEM”) shipments and revenues generally run ahead of aircraft delivery schedules. Consistent with prior years, our first quarter of fiscal 2026 shipments were a function of, among other things, the estimated 2025 and 2026 commercial aircraft production rates for Boeing and Airbus. Airline demand for new aircraft remains high and the OEMs continue to increase aircraft production. Commercial OEM sales increased in the first quarter of fiscal 2026 compared to fiscal 2025 partially due to the prior year Boeing union strike adversely impacting first quarter fiscal 2025 OEM sales as well as overall increases beginning in the latter half of fiscal 2025 and thus far in fiscal 2026 in aircraft production and del

The information called for by this item is provided under the caption “Description of Senior Secured Term Loans and Indentures” in Part I, 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 Annual Report on Form 10-K (for the fiscal year ended September 30, 2025, filed on November 12, 2025). These market risks have not materially changed for the first quarter of fiscal year 2026.

As of December 27, 2025, 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 Chief Financial Officer (Principal Financial Officer), of the effectiveness of the design and operation of TD Group’s disclosure controls and procedures. Based upon that evaluation, the President and Chief Executive Officer and Chief Financial Officer concluded that TD Group’s disclosure controls and procedures are effective to ensure that information required to be disclosed by TD Group in the reports it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified by the Securities and Exchange Commission’s rules and forms, and that such information is accumulated and communicated to TD Group’s management, including its President and Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, TD Group’s management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management necessarily was required to apply its judgment in designing and evaluating the controls and procedures.

During the fiscal quarter ended December 27, 2025, the Company completed the acquisition of Simmonds. The Company is currently integrating the acquisition into its operations, compliance programs and internal control processes. As permitted by SEC rules and regulations, the Company has excluded the acquisition from management's evaluation of internal controls over financial reporting as of December 27, 2025.

Changes in Internal Control over Financial Reporting

There have been no changes in the Company’s internal control over financial reporting that occurred during the fiscal quarter ended December 27, 2025, that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.
