*Special Note Regarding Forward-Looking Statements*

*This Annual Report on Form 10-K 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 Annual Report on Form 10-K. 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. Many factors mentioned in our discussion in this Annual Report on Form 10-K, including the risks outlined under "Risk Factors," will be important in determining future results. 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 outlined under "Risk Factors" in this 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 Annual Report on Form 10-K 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 Annual Report on Form 10-K 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.

In this report, the term "TD Group" refers to TransDigm Group Incorporated, which holds all of the outstanding capital stock of TransDigm Inc. The terms "Company," "TransDigm," "we," "us," "our" and similar terms, unless the context otherwise requires, refer to TD Group, together with TransDigm Inc. and its wholly-owned and majority-owned subsidiaries for which it has a controlling interest. References to "fiscal year" mean the year ending or ended September 30. For example, "fiscal year 2025" or "fiscal 2025" means the period from October 1, 2024 to September 30, 2025.

**PART I**

**ITEM 1.&nbsp;&nbsp;&nbsp;&nbsp;BUSINESS**

**The Company**

TD Group, through its wholly-owned subsidiary, TransDigm Inc., is a leading global designer, producer and supplier of highly engineered aircraft components that are critical to the safe and effective operation of nearly all commercial and military aircraft worldwide. Our products are represented in nearly every commercial and military aircraft in service today. Our business is well diversified due to the broad range of products we offer to our customers. We estimate that approximately 90% of our net sales for fiscal year 2025 were generated by proprietary products.

Most of our products generate significant aftermarket revenue. Once our parts are designed into and sold on a new aircraft, we generate net sales from aftermarket consumption over the life of that aircraft, which is generally estimated to be approximately 25 to 30 years. A typical platform can be produced for 20 to 30 years, giving us an estimated product life cycle in excess of 50 years. We estimate that approximately 55% of our net sales in fiscal year 2025 were generated from the aftermarket, the vast majority of which come from the commercial and military aftermarkets. Historically, these aftermarket revenues have produced a higher gross profit and have been more stable than net sales to original equipment manufacturers ("OEMs").

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

Our business strategy is made up of two key strengths: (1) successful execution of our value-driven operating strategy focused around our three core value drivers and (2) a selective acquisition strategy.

***Value-Driven Operating Strategy.*** Our three core value drivers are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Obtaining Profitable New Business.* We attempt to obtain profitable new business by using our technical expertise and application skill and our detailed knowledge of our customer base and the individual niche markets in which we operate. We have regularly been successful in identifying and developing both aftermarket and OEM products to drive our growth.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Improving Our Cost Structure.* We are committed to maintaining and continuously improving our lean cost structure through detailed attention to the cost of each of the products that we offer and our organizational structure, with a focus on reducing the cost of each.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Providing Highly Engineered Value-Added Products to Customers.* We focus on the engineering, manufacturing and marketing of a broad range of highly engineered niche products that we believe provide value to our customers. We believe we have been consistently successful in communicating to our customers the value of our products. This has generally enabled us to price our products to fairly reflect the value we provide and the resources required to do so.

***Selective Acquisition Strategy.*** 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. Since the inception of our company in 1993, we have acquired 95 businesses and various product lines. Refer to Note 2, "Acquisitions," in the notes to the consolidated financial statements included herein for information on the recent acquisitions.

**Products**

We primarily design, produce and supply 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 from our competitors by producing highly engineered products with high quality, reliability and timely delivery. Our proprietary products, and particularly our new product initiatives, are designed by our engineers and are intended to serve the needs of the aircraft component industry. These proprietary designs must withstand the extraordinary conditions and stresses that will be endured by products during use and meet the rigorous demands of our customers' tolerance and quality requirements. Our portfolio of products encompasses a vast array of essential components that play pivotal roles on commercial aerospace and defense platforms, as well as other products. For example, TransDigm's operating units make aircraft seatbelts and cockpit security systems that keep passengers and pilots safe; parachutes that protect military personnel; and specialized equipment for the National Aeronautics and Space Administration's ("NASA") space telescopes, aiding in space exploration and scientific advancement.

Our engineering costs are recorded in cost of sales and in selling and administrative expenses within our consolidated statements of income. Research and development costs are recorded in selling and administrative expenses within our consolidated statements of income. Refer to Note 1, "Summary of Significant Accounting Policies," in the notes to the consolidated financial statements included herein with respect to the total costs of research and development.

Primary customers of this segment are off-road vehicle suppliers and subsystem suppliers, child restraint system suppliers, satellite and space system suppliers, manufacturers of heavy equipment used in mining, construction and other industries and turbine original equipment manufacturers, gas pipeline builders and electric utilities.

For financial information about our segments, refer to Note 15, "Segments," in the notes to the consolidated financial statements included herein.

**Customers**

We predominantly serve customers in the commercial, regional, business jet and general aviation aftermarket, which generally account for 30% to 35% of our annual net sales; the commercial aerospace OEM market, comprising large commercial transport manufacturers and regional and business jet manufacturers, which generally account for 25% to 30% of our annual net sales; and the defense market (which includes defense OEMs and aftermarket sales to the U.S. and friendly foreign governments), which generally account for approximately 35% to 40% of our annual net sales.

Our customers include: (1) distributors of aerospace components; (2) worldwide commercial airlines, including national and regional airlines; (3) large commercial transport and regional and business aircraft OEMs; (4) various armed forces of the United States and friendly foreign governments; (5) defense OEMs; (6) system suppliers; and (7) various other industrial customers. Our top ten customers for fiscal year 2025 accounted for approximately 40% of our net sales. Products supplied to many of our customers are used on multiple platforms. None of our customers individually accounted for greater than 10% of our net sales for fiscal year 2025. We believe that our diversified revenue base reduces our dependence on any particular product, platform or market channel and has been a significant factor in maintaining our financial performance.

**Competition**

The niche markets within the aerospace industry that we serve are relatively fragmented and we face several competitors for many of the products and services we provide. Due to the global nature of the commercial aircraft industry, competition in these categories comes from both U.S. and foreign companies. Competitors in our product offerings range in size from divisions of large public corporations to small privately-held entities with only one or two components in their entire product portfolios.

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

We compete on the basis of engineering, manufacturing and marketing high quality and reliable products, which we believe meet or exceed the performance and maintenance requirements of our customers, consistent and timely delivery, and superior customer service and support. The industry's stringent regulatory, certification and technical requirements and the investments necessary in the development and certification of products may create disincentives for potential new competitors for certain products. If customers receive products that meet or exceed expectations and performance standards, we believe that they will have a reduced incentive to certify another supplier because of the cost and time of the technical design and testing certification process. In addition, we believe that the availability, dependability and safety of our products are reasons for our customers to continue long-term supplier relationships.

**Governmental Regulations**

The commercial aircraft component industry is highly regulated by the Federal Aviation Administration ("FAA") in the United States and by the European Union Aviation Safety Agency in Europe and other agencies throughout the world, while the military aircraft component industry is governed by military quality specifications. We, and the components we manufacture, are required to be certified by one or more of these entities or agencies, and, in many cases, by individual OEMs, in order to engineer and service parts and components used in specific aircraft models.

We must also satisfy the requirements of our customers, including OEMs and airlines that are subject to FAA regulations, and provide these customers with products and services that comply with the government regulations applicable to commercial flight operations. In addition, the FAA and other aviation authorities require that various maintenance routines be performed on aircraft components. We believe that we currently satisfy or exceed these maintenance standards in our repair and overhaul services. We also maintain several FAA-approved repair stations.

In addition, our businesses are subject to many other laws and requirements typically applicable to manufacturers and exporters. Without limiting the foregoing, sales of many of our products that will be used on aircraft owned by foreign entities are subject to compliance with export control laws and the manufacture of our products and the operations of our businesses, including the disposal of hazardous wastes, are subject to compliance with applicable environmental laws.

Refer to Item 1A. "Risk Factors" for additional information about the impact of government regulations on our business.

**Raw Materials**

We require the use of various raw materials in our manufacturing processes. We purchase a variety of manufactured component parts from various suppliers. We also purchase replacement parts, which are utilized in our various repair and overhaul operations. At times, we concentrate our orders among a few suppliers in order to strengthen our supplier relationships. Most of our raw materials and component parts are generally available from multiple suppliers at competitive prices.

**Intellectual Property**

We have various trade secrets, proprietary information, trademarks, trade names, patents, copyrights and other intellectual property rights, which we believe, in the aggregate but not individually, are important to our business. The Company's products are manufactured, marketed and sold using a portfolio of patents, trademarks, licenses, and other forms of intellectual property, some of which expire in the future. The Company develops and acquires new intellectual property on an ongoing basis. Based on the broad scope of the Company's product lines, management believes that the loss or expiration of any single intellectual property right would not have a material effect on our consolidated financial statements.

**Environmental Matters**

Our operations and facilities are subject to a number of federal, state, local and foreign environmental laws and regulations that govern, among other things, discharges of pollutants into the air and water, the generation, handling, storage and disposal of hazardous materials and wastes, the remediation of contamination and the health and safety of our employees. Environmental laws and regulations may require that the Company investigate and remediate the effects of the release or disposal of materials at sites associated with past and present operations. Certain facilities and third-party sites utilized by the Company have been identified as potentially responsible parties under the federal superfund laws and comparable state laws. The Company is currently involved in the investigation and remediation of a number of sites under applicable laws.

For information regarding environmental reserves, refer to Note 13, "Commitments and Contingencies," in the notes to the consolidated financial statements included herein. Compliance with federal, state, local and foreign environmental laws during fiscal 2025 did not have a material impact on our capital expenditures, results of operations or cash flows. Based upon consideration of currently available information, we believe liabilities for environmental matters will not have a material adverse impact on our consolidated financial statements, but we cannot assure that material environmental liabilities may not arise in the future. For further information on environmental-related risks, including climate change, refer to Item 1A. "Risk Factors."

**Human Capital Resources**

As of September 30, 2025, we had approximately 16,500 full-time, part-time and temporary employees. Approximately 15% of our full-time and part-time employees are represented by labor unions. Collective bargaining agreements between us and these labor unions expire at various dates up to January 2029.

We consider our employees to be our greatest asset. Succession planning and the development, attraction and retention of employees is critical for TransDigm and its operating units to sustain our three core value drivers (obtaining profitable new business, continually improving our cost structure and providing highly engineered value-added products to customers).

We have established development programs such as TransDigm University to empower internal career progression support the advancement of our employees. We also have established recruiting programs to identify and hire new talent such as the Management Development Program ("MDP"), which involved the recruiting of recent masters program graduates at certain colleges and universities, and the Junior Military Officer ("JMO") Program, which involves the recruiting of U.S. military veterans.

TransDigm's executive team also mentors rising talent on a more informal basis. This informal mentorship achieves a number of goals, including accelerating the development of top performers, fosters organizational learning, enhances employee performance and contributes to our retention efforts. The executive team dedicates substantial time to assessing our pool of future leaders, ensuring that we have the people and skills necessary to continue driving our business forward.

We offer attractive benefits packages that attract, retain, motivate and reward our talent, and we are committed to providing our employees and their families with programs that support their health and overall well-being. To empower our employees financially, we provide retirement savings plans and opportunities for tax-free savings through flexible spending accounts and health savings accounts. We believe that our compensation programs, including base pay, bonus structures and equity programs, fairly reward our employees for their hard work. Additionally, we understand the importance of maintaining a work-life balance, which is why our employees receive paid time off and enjoy designated holidays.

We understand the value in furthering the knowledge and education of our current employee base. In addition to formal and informal employee development programs within TransDigm and our operating units, employees can expand their careers by accessing tuition reimbursement programs. Some operating units also partner with local colleges to provide training courses to TransDigm employees. Access to programs such as these enhance our employees' value to the Company, our customers and our communities.

At TransDigm, we highly value the contributions of diverse perspectives, fresh ideas and varied experiences. Our commitment to diversity and inclusiveness is more than just an organizational goal; it is a fundamental principle that drives innovation, enhances our competitive edge and ultimately leads to better outcomes for all stakeholders. To gauge our progress, we annually review and assess our diversity initiatives and metrics.

Discrimination is not tolerated at TransDigm. We are committed to high ethical standards and equal employment opportunities in all personnel actions without regard to race, color, religion, gender, national origin, citizenship status, age, marital status, gender identity or expression, sexual orientation, physical or mental disability, or veteran status.

We are focused on establishing, maintaining and operating our facilities, with a strong emphasis on process safety and risk mitigation. Equally, we strive to empower and support our employees in preventing accidents and promoting a healthy work environment. We require our personnel to report and communicate risks, potential hazards, incidents and near misses so that we can investigate and establish appropriate measures to prevent future occurrences. To underscore our commitment to employee safety and well-being, we require each operating unit to individually report environmental, health and safety matters to our executive team monthly.

**Seasonality**

We do not believe our net sales are subject to significant seasonal variation; however, our net sales have generally been lower in the first quarter of our fiscal year compared to the subsequent quarters due to fewer working days resulting from the observance of various holidays.

**ITEM 1A.&nbsp;&nbsp;&nbsp;&nbsp;RISK FACTORS** 

*Below are material risks and uncertainties that could negatively affect our business and financial condition and could cause our actual results to differ materially from those expressed in forward-looking statements contained in this report. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business operations and financial condition. You should not interpret the disclosure of any risk factor to imply that the risk has not already materialized.*

**<u>Risks Related to our Strategy</u>**

**Our business focuses almost exclusively on the aerospace and defense industry.**

A period of significant market disruption in the aerospace and defense industry, or other macroeconomic factors, may disproportionately disrupt our business compared to more diversified peer companies.

**We may rely heavily on certain customers for much of our sales.**

In fiscal year 2025, no customer individually accounted for 10% or more of the Company's net sales; however, our top ten customers for fiscal year 2025 accounted for approximately 40% of our net sales. A material reduction in purchasing by one of our larger customers for any reason, including but not limited to general economic or aerospace downturns, decreased production, strike or resourcing, could have a material adverse effect on results of operations, financial position and cash flows.

**We generally do not have guaranteed future sales of our products. Further, when we enter into fixed price contracts with some of our customers, we take the risk for cost overruns.**

As is customary in our business, we do not generally have long-term contracts with most of our aftermarket customers and, therefore, do not have guaranteed future sales. Although we have long-term contracts with many of our OEM customers, many of those customers may terminate the contracts on short notice and, in most cases, our customers have not committed to buy any minimum quantity of our products. In addition, in certain cases, we must anticipate the future volume of orders based upon the historic purchasing patterns of customers and upon our discussions with customers as to their anticipated future requirements, and this anticipated future volume of orders may not materialize.

We also have entered into multi-year, fixed-price contracts with some of our customers, pursuant to which we have agreed to perform the work at a fixed price and, accordingly, realize all the benefit or detriment resulting from any decreases or increases in the costs of making these products. This risk is greater in a high inflationary environment. Sometimes we accept a fixed-price contract for a product that we have not previously produced, and this may increase the risk of cost overruns or delays in the completion of the design and manufacturing of the product. Most of our contracts do not permit us to recover increases in raw material prices, taxes or labor costs. Furthermore, entering into fixed-price contracts with the United States Government ("U.S. Government"), particularly for small-quantity or spot purchases made without reliable forecasts, exposes us to the risk of cost overruns and reduced margins if production costs increase or economies of scale cannot be achieved.

**We intend to pursue acquisitions. Our business may be adversely affected if we cannot consummate acquisitions on satisfactory terms, or if we cannot effectively integrate acquired operations.**

A significant portion of our growth has occurred through acquisitions. Future growth through acquisitions will be partially dependent upon the continued availability of suitable acquisition candidates at favorable prices and upon advantageous terms and conditions. We intend to pursue acquisitions that we believe will present opportunities consistent with our overall business strategy. However, we may not be able to find suitable acquisition candidates to purchase or may be unable to acquire desired businesses or assets on economically acceptable terms or may be unable to receive necessary regulatory approvals or support. In addition, we may not be able to raise the capital necessary to fund future acquisitions. Because we may actively pursue multiple opportunities simultaneously, we may encounter unforeseen expenses, complications and delays, including regulatory complications or difficulties in employing sufficient staff and maintaining operational and management oversight.

We regularly engage in discussions with respect to potential acquisition and investment opportunities. If we consummate an acquisition, our capitalization and results of operations may change significantly. Future acquisitions could result in margin dilution and further likely result in the incurrence of additional debt and contingent liabilities and an increase in interest and amortization expenses or periodic impairment charges related to goodwill and other intangible assets as well as significant charges relating to integration costs.

Acquisitions involve risks that the businesses acquired will not perform in accordance with expectations and that business judgments concerning the value, strengths and weaknesses of businesses acquired will prove incorrect. In addition, we may not be able to successfully integrate any business we acquire into our existing business. The successful integration of new businesses depends on our ability to manage these new businesses and cut excess costs. The successful integration of future acquisitions may also require substantial attention from our senior management and the management of the acquired business, which could decrease the time that they have to service, attract customers and develop new products and services or attend to other acquisition opportunities.

**Our indebtedness could adversely affect our financial health and could harm our ability to react to changes to our business and prevent us from fulfilling our obligations under our indebtedness.**

We have a significant amount of indebtedness and may be able to incur substantial additional indebtedness in the future. Although our senior secured credit facility and the indentures governing the various series of senior secured and senior subordinated notes outstanding (the "Notes") contain restrictions on the incurrence of additional indebtedness, these restrictions are subject to a number of significant qualifications and exceptions, and the indebtedness incurred in compliance with these qualifications and exceptions could be substantial. A breach of any of the covenants or an inability to comply with the required leverage ratio could result in a default under the senior secured credit facility or the indentures.

An increase in our indebtedness could also have other important consequences to investors. For example, it could:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increase our vulnerability to general economic downturns and adverse competitive and industry conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increase the risk we are subjected to downgrade or put on a negative watch by the ratings agencies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• require us to dedicate a substantial portion of our cash flows from operations to payments on our indebtedness, thereby reducing the availability of our cash flow to fund working capital requirements, capital expenditures, acquisitions, research and development efforts and other general corporate requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• place us at a competitive disadvantage compared to competitors that have less debt; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit, along with the financial and other restrictive covenants contained in the documents governing our indebtedness, among other things, our ability to borrow additional funds, make investments and incur liens.

All of the term loans under our term loan facility and the trade receivable securitization facility (the "Securitization Facility") bear interest at variable rates based on the Term Secured Overnight Financing Rate ("Term SOFR"). Accordingly, if Term SOFR increases, our debt service expense will also increase. In order to mitigate the interest rate risk of these variable rate borrowings, we enter into interest rate swap, cap, and collar agreements that cover a significant portion of the existing variable rate debt and may continue do so in the future, subject to market and other conditions.

Our indebtedness increases the possibility that we may be unable to generate cash sufficient to pay, when due, the principal of, interest on or other amounts due in respect of our indebtedness, including debt under the senior secured credit facility and the Notes. We cannot assure that our business will generate sufficient cash flow from operations or that future borrowings will be available to us under the senior secured credit facility or otherwise in amounts sufficient to enable us to service our indebtedness. If we cannot service our debt, we will have to take actions such as reducing or delaying capital investments, selling assets, restructuring or refinancing our debt or seeking additional equity capital.

**To service our indebtedness, we will require a significant amount of cash. Our ability to generate cash depends on many factors beyond our control and any failure to meet our debt service obligations could harm our business, financial condition and results of operations.**

Our ability to make payments on and to refinance our indebtedness, including the Notes, amounts borrowed under the senior secured credit facility, amounts due under our Securitization Facility, and to fund our operations, will depend on our ability to generate cash in the future, which, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control.

We cannot assure that our business will generate sufficient cash flow from operations, or that future borrowings will be available to us under the senior secured credit facility or otherwise in amounts sufficient to enable us to service our indebtedness, including the amounts borrowed under the senior secured credit facility, amounts borrowed under our Securitization Facility and the Notes, or to fund our other liquidity needs. If we cannot service our debt, we will have to take actions such as reducing or delaying capital investments, selling assets, restructuring or refinancing our debt or seeking additional equity capital. We cannot assure that any of these remedies could, if necessary, be effected on commercially reasonable terms, or at all. Our ability to restructure or refinance our debt will depend on the condition of the capital markets and our financial condition at such time. Any refinancing of our debt could be at higher interest rates and may require us to comply with more onerous covenants, which could further restrict our business operations. The terms of existing or future debt instruments, the Securitization Facility, the indentures governing the Notes and the senior secured credit facility may restrict us from adopting any of these alternatives. In addition, any failure to make payments of interest and principal on our outstanding indebtedness on a timely basis would likely result in a reduction of our credit rating, which could harm our ability to incur additional indebtedness on acceptable terms and could otherwise adversely affect our business, financial condition and results of operations.

**The terms of the senior secured credit facility and indentures governing the Notes may restrict our current and future operations, particularly our ability to respond to changes or to take certain actions.**

Our senior secured credit facility and the indentures governing the Notes contain a number of restrictive covenants that impose significant operating and financial restrictions on TD Group, TransDigm Inc. and its restricted subsidiaries (in the case of the senior secured credit facility) and TransDigm Inc. and its restricted subsidiaries (in the case of the indentures) and may limit their ability to engage in acts that may be in our long-term best interests. The senior secured credit facility and indentures governing the Notes include covenants restricting, among other things, the ability to (subject, in each case, to certain important exceptions):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• incur or guarantee additional indebtedness or issue preferred stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pay distributions on, redeem or repurchase our capital stock or redeem or repurchase our subordinated debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• make investments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sell assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• enter into agreements that restrict distributions or other payments from our restricted subsidiaries to us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• incur or allow to exist liens;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• consolidate, merge or transfer all or substantially all of our assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• engage in transactions with affiliates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• create unrestricted subsidiaries; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• engage in certain business activities.

A breach of any of these covenants could result in a default under the senior secured credit facility or the indentures governing the Notes. If any such default occurs, the lenders under the senior secured credit facility 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 senior secured credit facility also have the right in these circumstances to terminate any commitments they have to provide further borrowings. In addition, subject to the terms of an intercreditor agreement, following an event of default under the senior secured credit facility or the indentures governing our various series of outstanding senior secured notes, the lenders thereunder or the holders thereof, as applicable, 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 senior subordinated notes. If the debt under the senior secured credit facility or the Notes were to be accelerated, we cannot assure that our assets would be sufficient to repay in full the Notes and other debt.

**We are dependent on our executive officers, senior management team and highly trained employees and any work stoppage, difficulty hiring similar employees, or ineffective succession planning could adversely affect our business.**

Although we believe that our relations with our employees are satisfactory, we cannot assure that we will be able to negotiate a satisfactory renewal of collective bargaining agreements or that our employee relations will remain stable. Because we strive to limit the volume of finished goods inventory, any work stoppage could materially and adversely affect our ability to provide products to our customers.

In addition, our success depends in part on our ability to attract and motivate our senior management and key employees. Achieving this objective may be difficult due to a variety of factors, including fluctuations in economic and industry conditions, competitors' hiring practices, and the effectiveness of our compensation programs. Competition for qualified personnel can be intense. If we are unable to effectively provide for the succession of key personnel, senior management and our executive officers, including our President and Chief Executive Officer, our business, results of operations, cash flows and financial condition may be adversely affected. The Company's Board of Directors continually monitors this risk and we believe that the Company's succession plan, together with our straightforward strategy, clear value drivers, decentralized nature and the quality of managers running our operating units helps to mitigate this risk.

**Public health crises, and health pandemics, epidemics and outbreaks could adversely affect our business***.*

A significant public health crisis could cause disruption to our operations. Our ability to predict and respond to future changes resulting from potential health crises is uncertain. Even after a public health crisis subsides, there may be long-term effects on our business practices and customers in economies in which we operate that could severely disrupt our operations and could have a material adverse effect on our business, results of operations, cash flows and financial condition. As we cannot predict the duration, scope or severity of future public health crises, the negative financial impact to our results cannot be reasonably estimated and could be material.

**<u>Risks Related to our Operations</u>**

**Our sales to manufacturers of aircraft are cyclical, and a downturn in sales to these manufacturers may adversely affect us.**

Our sales to manufacturers of large commercial aircraft, such as Boeing, Airbus, and related OEM suppliers, as well as manufacturers of business jets have historically experienced periodic downturns. In the past, these sales have been affected by airline profitability, which is impacted by, among other things, fuel and labor costs, price competition, interest rates, downturns in the global economy and national and international events. In addition, sales of our products to manufacturers of business jets are impacted by, among other things, downturns in the global economy. Significant labor disagreements and supply chain issues may also negatively impact the production of aircraft. Downturns adversely affect our results of operations, financial position and cash flows.

**Our business is dependent on the availability of certain components and raw materials from suppliers.**

Our business is affected by the price and availability of the raw materials and component parts that we use to manufacture our components. Our business, therefore, could be adversely impacted by factors affecting our suppliers (such as the destruction of our suppliers' facilities or their distribution infrastructure, a work stoppage or strike by our suppliers' employees or the failure of our suppliers to provide materials of the requisite quality), or by increased costs of such raw materials or components if we were unable to pass along such price increases to our customers. Changes to tariff and import and export regulations in the United States and abroad may also negatively impact the availability and pricing of raw materials.

Because we strive to limit the volume of raw materials and component parts on hand, our business could be adversely affected if we were unable to obtain these raw materials and components from our suppliers in the quantities we require or on favorable terms. Although we believe in most cases that we could identify alternative suppliers, or alternative raw materials or component parts, the lengthy and expensive aviation authority and OEM certification processes associated with aerospace products could prevent efficient replacement of a supplier, raw material or component part.

**We face significant competition.**

We operate in a highly competitive global industry and compete against a number of companies. Competitors in our product lines are both U.S. and foreign companies and range in size from divisions of large public corporations to small privately-held entities. We believe that our ability to compete depends on high product performance, consistent high quality, short lead-time and timely delivery, competitive pricing, superior customer service and support and continued certification under customer quality requirements and assurance programs. We adjust the prices of some of our products from time to time to stay competitive.

**Climate-related regulations designed to address climate change may result in additional compliance costs.**

Our operations and the products we sell are currently subject to rules limiting emissions and to other climate-related regulations in certain jurisdictions where we operate. Changes in environmental and climate-related laws or regulations on greenhouse gas emissions may negatively impact us, our suppliers and customers. We cannot predict what environmental legislation or regulations will be enacted in the future, how existing or future laws or regulations will be administered or interpreted, or what environmental conditions may be found to exist. Compliance with any new or more stringent laws or regulations, or stricter interpretations of existing laws, could require additional expenditures by us or our suppliers, in which case, the costs of raw materials and component parts could increase.

Because our manufacturing facilities primarily engage in assembly and light manufacturing and because we do not maintain any transportation infrastructure, we have relatively low Scope 1 and Scope 2 emissions. Accordingly, we do not anticipate any material adverse impact from increased carbon regulation directly on our manufacturing operations. Further, because of our wide portfolio of hundreds of thousands of products, we do not anticipate any material adverse impact from the reliance on a supplier or group of suppliers that may be subject to climate risks. However, regulation that would have a material adverse impact on air travel could have a material adverse impact on our business. Given the uncertainty around these issues, we cannot predict how future legislation, will affect our operations and financial condition. We have established a science-aligned greenhouse gas emissions reduction target of at least a 50% reduction in our Scope 1 and Scope 2 emissions on an absolute basis. Fiscal 2019 is the selected baseline year for TransDigm that we will compare against as we make progress towards our emissions reduction goal. We continue to evaluate ways to reduce our energy and water consumption and lower our greenhouse gas emissions through energy efficiency measures, the purchase of green power and other actions.

**Our operations depend on our manufacturing facilities, which are subject to physical and other risks that could disrupt production.**

Our operations and those of our customers and suppliers have been and may again be subject to natural disasters, climate change-related events, pandemics or other business disruptions, which could seriously harm our results of operation and increase our costs and expenses. Some of our manufacturing facilities are located in regions that may be impacted by severe weather events, such as increased storm frequency or severity in the Atlantic and fires in hotter and drier climates. These could result in potential damage to our physical assets as well as disruptions in manufacturing activities. Some of our manufacturing facilities are located in areas that may be at risk due to rising sea levels. Moreover, some of our manufacturing facilities are located in areas that could experience decreased access to water due to climate issues.

We are also vulnerable to damage from other types of disasters, including power loss, fire, explosions, floods, communications failures, terrorist attacks and similar events. Disruptions could also occur due to health-related outbreaks and crises, cyber-attacks, computer or equipment malfunction (accidental or intentional), operator error or process failures. Should insurance or other risk transfer mechanisms, such as our existing disaster recovery and business continuity plans, be insufficient to recover all costs, we could experience a material adverse effect on our business, results of operations, financial position and cash flows.

**Operations and sales outside of the United States may be subject to additional risks.**

Our net sales to foreign customers were $3,296 million for the fiscal year ended September 30, 2025. A number of risks inherent in international operations could have a material adverse effect on our results of operations, including war, sanctions, global health crises, currency fluctuations, difficulties in staffing and managing multinational 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.

Issues with the global supply chain can also rise due to some of the aforementioned risks, as well as the availability and cost of raw materials to suppliers, merchandise quality or safety issues, shipping and transport availability and cost, increases in wage rates and taxes, transport security, inflation and other factors relating to the suppliers and the countries in which they are located or from which they import. Such issues are often beyond our control and could adversely affect our operations and profitability. Furthermore, the Company is subject to foreign and domestic laws and regulations, which generally prohibit companies and their employees, agents and contractors from making improper payments for the purpose of obtaining or retaining business. Failure to comply with these laws could subject the Company to civil and criminal penalties that could materially adversely affect the Company's results of operations, financial position and cash flows.

We continue to monitor the ongoing geopolitical conflicts, such as Russia and Ukraine, and the related export controls and financial and economic sanctions imposed on certain industry sectors, including the aviation sector, and parties in Russia by the U.S., the U.K., the European Union and others. Although the conflicts have not, nor are expected to, have a direct material adverse impact on TransDigm's business, the implications of these conflicts in the short-term and long-term are difficult to predict. Factors such as increased energy costs, the availability of certain raw materials for aircraft manufacturers, embargoes on flights from certain airlines, sanctions on certain companies, and the stability of certain customers could impact the global economy and aviation sector.

**We are subject to certain unique business risks as a result of supplying equipment and services to the U.S. Government.**

Companies engaged in supplying defense-related equipment and services to U.S. Government agencies, whether through direct contracts with the U.S. Government or as a subcontractor to customers contracting with the U.S. Government, are subject to business risks specific to the defense industry. These risks include the ability of the U.S. Government to unilaterally:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• suspend or debar us from receiving new contracts based on alleged violations of procurement laws or regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• terminate existing contracts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• revoke required security clearances; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• audit contract-related costs and fees, including allocated indirect costs.

U.S. Government contracts can be terminated by the U.S. Government at its convenience without cause or significant notice. Termination for convenience provisions provide only for recovery of costs incurred or committed, settlement expenses and profit on the work completed prior to termination.

Most of our U.S. Government contracts are based on a firm-fixed price where we take the risk of cost overruns. On contracts for which the price is not fixed but rather based on the reimbursement of costs, the U.S. Government may review incurred costs and performance, as well as our accounting and general business practices. Based on the results of such audits, the U.S. Government may adjust the reimbursement of contract-related costs and fees, including allocated indirect costs. In addition, under U.S. Government purchasing regulations, some of our costs, including most financing costs, amortization of intangible assets, portions of research and development costs, and certain marketing expenses may not be subject to reimbursement under cost-reimbursement contracts.

Furthermore, even where the price is not based on cost, the U.S. Government may seek to review costs to determine whether our pricing is "fair and reasonable." Our subsidiaries are periodically subject to pricing reviews and government buying agencies that purchase some of our subsidiaries' products are periodically subject to audits by the U.S. Department of Defense ("DOD") with respect to prices paid for such products. As a result of these audits, we could be asked to enter into an arrangement whereby our prices would be based on costs approved by the auditor, plus a nominal fee, the DOD could seek to pursue alternative sources of supply for our parts, or the U.S. Government could take other adverse actions with respect to our contracts. Any of those occurrences could lead to a reduction in our revenue from, or the profitability of certain of our supply arrangements with, certain agencies and buying organizations of the U.S. Government. Further, negative publicity relating to the results of any audit, inquiry or subsequent hearing or the like could negatively impact our stock price.

If a government inquiry or investigation alleges improper or illegal activities, we could be subject to civil or criminal penalties or administrative sanctions, including contract termination, fines, forfeiture of fees, suspension of payment and suspension or debarment from doing business with U.S. Government agencies, any of which could materially adversely affect our reputation, business, financial condition, results of operations and cash flows.

Moreover, U.S. Government purchasing regulations contain many additional operational requirements, which do not apply to entities not engaged in government contracting. Failure to comply with such government contracting requirements could result in civil and criminal penalties that could have a material adverse effect on the Company's results of operations.

**Our business may be adversely affected if we would lose our government or industry approvals or if more stringent government regulations are enacted or if industry oversight is increased.**

The aerospace industry is highly regulated in the U.S. and in other countries. In order to sell our products, we and the products we manufacture must be certified by the FAA, the DOD and similar agencies in foreign countries and by individual manufacturers. If new and more stringent government regulations are adopted or if industry oversight increases, we might incur significant expenses to comply with any new regulations or heightened industry oversight. In addition, if material authorizations or approvals were revoked or suspended, our business would be adversely affected.

In addition to the aviation approvals, we are at times required to obtain approval from U.S. Government agencies and similar agencies elsewhere in the world to export our products. U.S. laws and regulations applicable to us include the Arms Export Control Act, the International Traffic in Arms Regulations ("ITAR"), the Export Administration Regulations ("EAR") and the trade sanctions laws and regulations administered by the United States Department of the Treasury's Office of Foreign Assets Control ("OFAC"). EAR restricts the export of commercial and dual-use products and technical data to certain countries, while ITAR restricts the export of defense products, technical data and defense services.

Failure to obtain approval to export or determination by the U.S. Government or similar agencies elsewhere in the world that we failed to receive required approvals or licenses could eliminate or restrict our ability to sell our products outside the United States or other country of origin, and the penalties that could be imposed by the U.S. Government or other applicable government for failure to comply with these laws could be significant.

**We could incur substantial costs as a result of data protection concerns.**

The interpretation and application of data protection laws in the U.S. and globally, including but not limited to the General Data Protection Regulation and are uncertain and evolving. It is possible that these laws may be interpreted and applied in a manner that is inconsistent with our data practices. Complying with these various laws is difficult and could cause us to incur substantial costs or require us to change our business practices in a manner adverse to our business. Further, although we have implemented internal controls and procedures designed to ensure compliance with the various privacy-related laws, rules and regulations, there can be no assurance that our controls and procedures will enable us to be fully compliant with all data protection laws. The rapid evolution and increased adoption of artificial intelligence ("AI") technologies may intensify these risks. Any failure to comply, could result in significant penalties, fines, legal challenges and reputational harm.

**Increased cybersecurity threats and more sophisticated and targeted computer crime have posed and could continue to pose a risk to our and certain third parties' information technology systems and a disruption to or breach in the security of such systems, if material, could have adverse effects on our result of operations and financial condition.**

We rely extensively on information technology systems to manage and operate our business, some of which are managed by third parties. The security and functionality of these information technology systems, and the processing of data by these systems, are critical to our business operations. If these systems, or any part of the systems, are damaged, intruded upon, attacked, shutdown or cease to function properly (whether by planned upgrades, force majeure, telecommunications failures, criminal acts, including hardware or software break-ins, ransomware attacks or extortion attempts, or viruses, or other cybersecurity incidents) and we suffer any resulting interruption in our ability to manage and operate our business or if our products are affected, our results of operations and financial condition could be materially adversely affected. In fact, we have experienced data security incidents, although these have not had a material impact on our financial results. Furthermore, the Company has access to classified, sensitive, confidential, proprietary, or personal data or information that is subject to privacy and security laws, regulations, or other contractually-imposed controls.

------

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

The risks in this area continue to grow, and we expect cyber events will continue to accelerate in frequency and impact as threat actors increasingly use AI and other techniques to circumvent security controls, evade detection and remove forensic evidence.

Despite our use of reasonable and appropriate technical security controls and monitoring, security breaches, theft, misplaced, lost or corrupted data, programming, or employee errors and/or malfeasance have led and could in the future lead to the compromise or improper use of such sensitive, confidential, proprietary, or personal data or information. Such events may result in possible negative consequences, such as disruption to our business operations, loss of proprietary information, ransom demands, loss of revenue, penalties, failure to comply with laws governing sensitive data, government enforcement, litigation or regulatory proceedings, negative publicity, loss of reputation, loss of intellectual property, loss of competitiveness or customers, increased security and compliance costs or other negative consequences; however, the use of isolated systems by our operating units mitigates the pervasiveness of this risk. Further, the amount of insurance coverage that we maintain may be inadequate to cover claims or liabilities relating to a cybersecurity incident. Depending on the nature and magnitude of these events, they may have an adverse impact on our results of operations or financial condition.

**<u>Risks Related to Legal and Regulatory Matters</u>**

**We could incur substantial costs as a result of violations of or liabilities under environmental laws and regulations.**

Our operations and facilities are subject to a number of federal, state, local and foreign environmental laws and regulations that govern, among other things, discharges of pollutants into the air and water, the generation, handling, storage and disposal of hazardous materials and wastes, the remediation of contamination and the health and safety of our employees. Environmental laws and regulations may require that the Company investigate and remediate the effects of the release or disposal of materials at sites associated with past and present operations. Certain facilities and third-party sites utilized by subsidiaries of the Company have been identified as potentially responsible parties under the federal superfund laws and comparable state laws. The Company is currently involved in the investigation and remediation of a number of sites under applicable laws.

Estimates of the Company's environmental liabilities are based on current facts, laws, regulations and technology. These estimates take into consideration the Company's prior experience and professional judgment of the Company's environmental advisors. Estimates of the Company's environmental liabilities are further subject to uncertainties regarding the nature and extent of site contamination, the range of remediation alternatives available, evolving remediation standards, imprecise engineering evaluations and cost estimates, the extent of corrective actions that may be required and the number and financial condition of other potentially responsible parties, as well as the extent of their responsibility for the remediation.

Accordingly, as investigations and remediations proceed, it is likely that adjustments in the Company's accruals will be necessary to reflect new information. The amounts of any such adjustments could have a material adverse effect on the Company's results of operations or cash flows in a given period. Based on currently available information, however, the Company does not believe that future environmental costs in excess of those accrued with respect to sites for which the Company has been identified as a potentially responsible party are likely to have a material adverse effect on the Company's financial condition.

**We may be subject to periodic litigation and regulatory proceedings, which may adversely affect our business and financial performance.**

Our business is subject to regulation under a variety of U.S. federal and state and non-U.S. laws, regulation and policies that require ongoing compliance efforts. From time to time, we are involved in lawsuits and regulatory actions brought or threatened against us in the ordinary course of business. These actions and proceedings may involve claims for, among other things, compensation for alleged personal injury, workers' compensation, employment discrimination, financial improprieties or breach of contract. In addition, we may be subject to class action lawsuits, including those involving allegations of violations of consumer product statutes or the Fair Labor Standards Act and state wage and hour laws. Due to the inherent uncertainties of litigation, we cannot accurately predict the ultimate outcome of any such actions or proceedings. The outcome of litigation, particularly class action lawsuits and regulatory actions, is difficult to assess or quantify, as plaintiffs may seek recovery of very large or indeterminate amounts in these types of lawsuits, and the magnitude of the potential loss may remain unknown for substantial periods of time. In addition, plaintiffs in many types of actions may seek punitive damages, civil penalties, consequential damages or other losses, or injunctive or declaratory relief. These proceedings could result in substantial cost and may require us to devote substantial resources to defend ourselves. The ultimate resolution of these matters through settlement, mediation, or court judgment could have a material impact on our financial condition, results of operations, and cash flows.

**We could be adversely affected by the impact of failure, misuse or quality issues of our products.**

We produce highly engineered aircraft components, and accordingly, the adverse impact of product quality issues, actual or perceived, can be significant. Our operations expose us to potential liabilities for personal injury or death as a result of the failure of an aircraft product that we have designed, manufactured or serviced. While we maintain liability insurance to protect us from future product liability claims, in the event of product liability claims our insurers may attempt to deny coverage or any coverage we have may not be adequate. We also may not be able to maintain insurance coverage in the future at an acceptable cost. Any liability not covered by insurance or for which third-party indemnification is not available could result in significant liability to us.

------

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

In addition, a crash caused by one of our products could damage our reputation for quality products. We believe our customers consider safety and reliability as key criteria in selecting a provider of aircraft products. If a crash were to be caused by one of our products, or if we were to otherwise fail to maintain a satisfactory record of safety and reliability, our ability to retain and attract customers may be materially adversely affected.

**<u>Risks Related to Financial Matters</u>**

**We have recorded a significant amount of intangible assets, which may never generate the returns we expect.**

Mergers and acquisitions have resulted in significant increases in identifiable intangible assets and goodwill. Identifiable intangible assets, which primarily include trademarks, trade names, customer relationships, and technology, were $3,454 million at September 30, 2025, representing 15% of our total assets. Goodwill recognized in accounting for mergers and acquisitions was $10,612 million at September 30, 2025, representing 46% of our total assets. We may never realize the full value of our identifiable intangible assets and goodwill, and to the extent we were to determine that our identifiable intangible assets or our goodwill were impaired within the meaning of applicable accounting standards, we would be required to write-off the amount of any impairment.

**We may be subject to risks relating to changes in our tax rates or exposure to additional income tax liabilities.**

We are subject to income taxes in the U.S. and various non-U.S. jurisdictions. The Company's domestic and international tax liabilities are dependent upon the location of earnings among these different jurisdictions. The Company's future results of operations could be adversely affected by changes in the Company's effective tax rate as a result of changes in the mix of earnings in countries with differing statutory tax rates, changes in the valuation of deferred tax assets, challenges by tax authorities or changes in tax laws or regulations. From time to time, changes in tax laws or regulations may be proposed or enacted that could adversely affect our overall tax liability. There can be no assurance that changes in tax laws or regulations, both within the U.S. and the other jurisdictions in which we operate, such as the proposed 15% global minimum tax under the Organisation for Economic Co-operation and Development (the "OECD") Pillar Two, Global Anti-Base Erosion Rules (the "Pillar Two Rules"), will not materially and adversely affect our effective tax rate, tax payments, financial condition and results of operations. As of September 30, 2025, many jurisdictions where the Company operates, including Canada, U.K. and Germany, have adopted the Pillar Two Rules. The effective dates vary between fiscal 2025 and fiscal 2026.

In addition, the amount of income taxes paid by the Company is subject to ongoing audits by U.S. federal, state and local tax authorities and by non-U.S. tax authorities. If these audits result in assessments different from amounts reserved, future financial results may include unfavorable adjustments to the Company's tax liabilities, which could have a material adverse effect on the Company's results of operations.

**We do not regularly declare and pay quarterly or annual cash dividends on our stock.**

Notwithstanding the most recent special cash dividend declared by the Company's Board of Directors on August 20, 2025 of $90.00 per outstanding share of common stock, paid on September 12, 2025, we do not anticipate declaring regular cash dividends, whether quarterly or annual, on our common stock or any other equity security in the foreseeable future.

The amounts that may be available to us to pay future special cash dividends are restricted under our debt and other agreements. Any payment of special cash dividends on our common stock in the future will be at the discretion of our Board of Directors and will depend on our results of operations, earnings, capital requirements, financial condition, future prospects, contractual restrictions and other factors deemed relevant by our Board of Directors. Therefore, shareholders should not rely on regular quarterly or annual dividend income from shares of our common stock and should not rely on special dividends with any regularity or at all.

**<u>General Risks</u>**

**Our commercial business is sensitive to the number of flight hours that our customers' planes spend aloft, the size and age of the worldwide aircraft fleet and our customers' profitability. These items are, in turn, affected by general economic and geopolitical and other worldwide conditions.**

Our commercial business is directly affected by, among other factors, changes in revenue passenger kilometers ("RPKs"), the size and age of the worldwide aircraft fleet, the percentage of the fleet that is out-of-warranty and changes in the profitability of the commercial airline industry. RPKs and airline profitability have historically been correlated with the general economic environment, although national and international events also play a key role, such as pandemics, general downturns in the global economy, higher fuel prices and conflicts abroad.

In addition, global market and economic conditions have been challenging due to turbulence in the U.S. and international markets and economies and have prolonged declines in business and consumer spending. During periods of reduced airline profitability, some airlines may delay purchases of spare parts, preferring instead to deplete existing inventories, and delay refurbishments and discretionary spending. If demand for spare parts decreases, there would be a decrease in demand for certain products. An adverse change in demand could impact our results of operations, collection of accounts receivable and our expected cash flow generation from current and acquired businesses which may adversely impact our financial condition and access to capital markets.

**U.S. military spending is dependent upon the U.S. defense budget.**

The military and defense market is significantly dependent upon government budget trends, particularly the DOD budget. In addition to normal business risks, our supply of products to the U.S. Government is subject to unique risks largely beyond our control. DOD budgets could be negatively impacted by several factors, including, but not limited to, a change in defense spending policy as a result of the presidential election or otherwise, the U.S. Government's budget deficits, spending priorities, the cost of sustaining the U.S. military presence internationally and possible political pressure to reduce U.S. Government military spending, each of which could cause the DOD budget to remain unchanged or to decline. A significant decline in U.S. military expenditures could result in a reduction in the amount of our products sold to the various agencies and buying organizations of the U.S. Government.

**Our stock price may be volatile, and an investment in our common stock could suffer a decline in value.**

There has been significant volatility in the market price and trading volume of equity securities, which is unrelated to the operating performance of the companies issuing the securities. These market fluctuations may negatively affect the market price of our common stock. Shareholders may not be able to sell their shares at or above the purchase price due to fluctuations in the market price of our common stock. Such changes could be caused by changes in our operating performance or prospects, including possible changes due to the cyclical nature of the aerospace industry and other factors such as fluctuations in OEM and aftermarket ordering, which could cause short-term swings in profit margins. Or such changes could be unrelated to our operating performance, such as changes in market conditions affecting the stock market generally or the stocks of aerospace companies or changes in the outlook for our common stock, such as changes to or the confidence in our business strategy, changes to or confidence in our management, or expectations for future growth of the Company.

**ITEM 1B.&nbsp;&nbsp;&nbsp;&nbsp;UNRESOLVED STAFF COMMENTS**

None.

**ITEM 1C.&nbsp;&nbsp;&nbsp;&nbsp;CYBERSECURITY**

We have established a risk-based cybersecurity and information security program ("program") designed to assess, identify, and manage material risks from cybersecurity threats. Our cybersecurity risk management process includes policies that specify the requirements for technical security controls, monitoring systems, tools and services from third-party providers, and employee training and awareness. Our cybersecurity risk management process also includes regular independent audits across our operating units. Management oversees our cybersecurity risk management process in order to assess and manage material risks from cybersecurity threats identified by both internal and external threat intelligence. Our program monitors and evaluates risks from cybersecurity threats, and we aim to adapt our program and related processes accordingly.

The multi-layered framework on which our cybersecurity and information security program is built incorporates cybersecurity standards and certain requirements of the National Institute of Standards and Technology ("NIST") Special Publication 800-171—Protecting Controlled Unclassified Information in Non-Federal Systems and Organizations—along with other legal and regulatory requirements. However, this does not mean that we meet any particular technical standards, specifications, or requirements, but rather that we use NIST and other cybersecurity standards as a guide to help us identify, assess, and manage cybersecurity risks relevant to our business.

Our cybersecurity and information security program is led by the Company's Vice President of Cybersecurity ("VPoC") who reports to our Chief Financial Officer. Our VPoC has served as a technology leader of cybersecurity, information security, infrastructure, and operational functions for over 35 years. The VPoC is supported by the Incident Response Team ("IRT"), a management committee made up of the Co-Chief Operating Officers, Chief Financial Officer, and executives in legal, finance, IT, and audit. The IRT supports the VPoC in assessing and managing risks from cybersecurity threats and in the event of a cybersecurity incident, provides oversight and leadership with respect to incident response.

As adopted by our businesses, which has been overseen by our corporate executive team, we have a cybersecurity incident response plan that outlines our policies and procedures to identify, respond to, and recover from cybersecurity threats and cybersecurity incidents. Our businesses are required to conduct regular exercises of their incident response plan as part of our program.

In the event of a potentially material cybersecurity incident, as determined by the VPoC with support from legal, as needed, the IRT is notified through an established escalation protocol. The Chair of the Audit Committee is also notified and briefed, and meetings of the Audit Committee and/or full Board of Directors would be held as appropriate. We maintain a relationship with third-party forensic vendor(s) available for incident response and investigation. Additionally, we maintain cybersecurity insurance.

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

The Company's Board of Directors oversees our enterprise risk management ("ERM") program and has delegated the primary responsibility for its oversight, which includes oversight of cybersecurity risk, to the Audit Committee. The Audit Committee is informed of material risks from cybersecurity threats through regular discussion with management regarding cybersecurity risk mitigation and cybersecurity incident management. Executive management, including our VPoC, regularly presents to the Audit Committee regarding cybersecurity matters, including program updates, key metrics, and developments.

The ERM program inventories and classifies key risk areas. We employ a methodology for scoring the risks based on the probability and impact of individual risks and discuss and implement countermeasures to address the risks.

Based on the information we have as of the date of this Annual Report on Form 10-K, we do not believe any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect our business strategy, results of operations or financial condition. For further information about risks related to cybersecurity threats, refer to Item 1A. "Risk Factors."

**ITEM 2.&nbsp;&nbsp;&nbsp;&nbsp;PROPERTIES**

Our corporate headquarters is located in Cleveland, Ohio. We maintain approximately 120 manufacturing facilities. Most of our manufacturing facilities are comprised of manufacturing, distribution and engineering functions, and most facilities have certain administrative functions, including management, sales and finance and are a combination of leased and owned. The facilities are situated in 25 states within the United States and in 14 other countries. Our properties consist of sales and administrative offices and distribution centers as well as manufacturing plants. None of our facilities are individually material to our operations.

Management believes that our machinery, plants and offices are in satisfactory operating condition and that it will have sufficient capacity to meet foreseeable future needs without incurring significant additional capital expenditures.

**ITEM 3.&nbsp;&nbsp;&nbsp;&nbsp;LEGAL PROCEEDINGS**

The Company is involved in various claims and legal actions arising in the ordinary course of business. We believe that the outcome of these matters will not have a material adverse effect on our financial position, results of operations, or cash flows. From time to time, we are involved in matters that involve governmental authorities as a party under federal, state and local laws that have been enacted or adopted regulating the discharge of materials into the environment or primarily for the purpose of protecting the environment. We will report such matters that exceed, or that we reasonably believe may exceed, $1 million or more in monetary sanctions. While the Company is currently involved in certain legal proceedings, it believes the results of these proceedings will not have a material adverse effect on its financial condition, results of operations, or cash flows.

**Special Dividends** 

On August 20, 2025, the Company's Board of Directors authorized and declared a special cash dividend of $90.00 on each outstanding share of common stock and cash dividend equivalent payments on eligible vested options outstanding under its stock option plans. The total cash payment, funded by a combination of $5,000 million in new senior secured and unsecured debt and existing cash on hand, related to the special dividend and dividend equivalents was approximately $5,232 million in September 2025.

Any future declaration of special cash dividends on our common stock will be at the discretion of our Board of Directors and will depend upon our results of operations, earnings, capital requirements, financial condition, future prospects, contractual restrictions under the Second Amended and Restated Credit Agreement dated as of June 4, 2014 (the "Credit Agreement") and indentures governing the Notes, the availability of surplus under Delaware law and other factors deemed relevant by our Board of Directors. TD Group is a holding company and conducts all of its operations through direct and indirect subsidiaries. Unless TD Group receives dividends, distributions, advances, transfers of funds or other payments from our subsidiaries, TD Group will be unable to pay any dividends on our common stock in the future. The ability of any subsidiaries to take any of the foregoing actions is limited by the terms of our term loans and indentures and may be limited by future debt or other agreements that we may enter into.

**ITEM 7.&nbsp;&nbsp;&nbsp;&nbsp;MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

*The following discussion of our 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 report. The following discussion may contain predictions, estimates and other forward-looking statements that involve a number of risks and uncertainties, including those discussed under the heading entitled "Risk Factors" included elsewhere in this report. These risks could cause our actual results to differ materially from any future performance suggested below.*

**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 we believe that 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 fiscal year 2025, we generated net sales of $8,831 million, gross profit of $5,311 million or 60.1% of net sales, and net income attributable to TD Group of $2,074 million.

In fiscal 2025, demand for air travel remained strong both domestically and internationally. Commercial aftermarket sales increased in fiscal 2025 compared to fiscal 2024 primarily due to the overall demand for air travel resulting in higher flight hours and utilization of passenger and freight aircraft as global air traffic continues to surpass pre-pandemic levels. In recent months, international air traffic growth has been outpacing domestic growth. Passenger load factors remain strong and have reached record levels in recent months in certain markets.

Our commercial transport OEM shipments and revenues generally run ahead of aircraft delivery schedules. Consistent with prior years, our fiscal 2025 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 are working to increase aircraft production. However, aircraft production rates remain well below pre-pandemic levels as the struggles in the OEM supply chain and labor challenges persist, along with geopolitical challenges, though progress continues to be made in the build rates. Airbus has also encountered difficulties in ramping up production. For fiscal 2025, the impact across TransDigm's operating units was uneven and varied, resulting in consolidated commercial OEM sales decreasing compared to fiscal 2024.

Our defense business fluctuates from year-to-year, and is dependent, to a degree, on government budget constraints, the timing of orders, macro and micro dynamics with respect to the DOD procurement policy and the extent of global conflicts, such as the ongoing geopolitical conflicts. Likewise, delays in government spending outlays and government funding reprioritization can impact demand. For a variety of reasons, the military spending outlook is very uncertain, though recent DOD budgets have trended upwards due to recent geopolitical challenge and conflicts, and current military modernization efforts. Defense sales in fiscal 2025 increased compared to fiscal 2024 primarily due to continued U.S. Government defense spend outlays.

At various points in 2025, the U.S. Government announced new or higher tariffs on goods imported into the U.S. from numerous countries resulting in multiple countries countering with reciprocal tariffs and other actions in response. Negotiations between the U.S. and other countries regarding the tariffs are ongoing and their status continues to evolve. TransDigm is primarily a domestic manufacturer. Because of this, tariffs did not have a significant impact on our fiscal 2025 operating results and we do not expect the tariffs to have a significant impact on our fiscal 2026 operating results. However, we continue to monitor the developments on tariffs and other changes in trade policy for its potential impact on the economic environment and on our business and operating results.

**Changes in Results of Operations**

**Fiscal year ended September 30, 2025 compared with fiscal year ended September 30, 2024** 

**<u>Total Company</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Net Sales*.** Net organic sales and acquisition sales and the related dollar and percentage changes for the fiscal years ended September 30, 2025 and 2024 were as follows (amounts in millions):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Fiscal Years Ended** | **Fiscal Years Ended** | | **% Change<br>Net Sales** |
| | **September 30, 2025** | **September 30, 2024** | **Change** | **% Change<br>Net Sales** |
| Organic sales | $8510 | $7895 | $615 | 7.7% |
| Acquisition sales | 321 | 45 | 276 | 3.5% |
| &nbsp;&nbsp;&nbsp;&nbsp;Net sales | $8831 | $7940 | $891 | 11.2% |

---

Organic sales represent net sales from existing businesses owned by the Company, excluding sales from acquisitions. Acquisition sales represent net sales from acquired businesses for the period up to one year from the respective acquisition date. We believe this measure provides investors with a supplemental understanding of underlying sales trends by providing sales growth on a consistent basis. Refer to Note 2, "Acquisitions," in the notes to the consolidated financial statements included herein for information on the Company's recent acquisitions.

The increase in organic sales of $615 million for the fiscal year ended September 30, 2025 compared to the fiscal year ended September 30, 2024 is primarily related to increases in defense and commercial aftermarket.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Cost of Sales and Gross Profit*.** Cost of sales increased by $252 million or 7.7%, to $3,520 million for the fiscal year ended September 30, 2025 compared to $3,268 million for the fiscal year ended September 30, 2024. Cost of sales and the related percentage of net sales for the fiscal years ended September 30, 2025 and 2024 were as follows (amounts in millions):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Fiscal Years Ended** | **Fiscal Years Ended** | | |
| | **September 30, 2025** | **September 30, 2024** | **Change** | **% Change** |
| Cost of sales - excluding costs below | $3536 | $3241 | $295 | 9.1% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of net sales | 40.0% | 40.8% |  |  |
| Non-cash stock and deferred compensation expense | 15 | 21 | (6) | (28.6)% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of net sales | 0.2% | 0.3% |  |  |
| Inventory step-up amortization | 10 | 21 | (11) | (52.4)% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of net sales | 0.1% | 0.3% |  |  |
| Foreign currency losses | 10 | 20 | (10) | (50.0)% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of net sales | 0.1% | 0.3% |  |  |
| Loss contract amortization | (51) | (35) | (16) | (45.7)% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of net sales | (0.6)% | (0.4)% |  |  |
| Total cost of sales | $3520 | $3268 | $252 | 7.7% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of net sales | 39.9% | 41.2% |  |  |
| Gross profit (Net sales less Total cost of sales) | $5311 | $4672 | $639 | 13.7% |
| Gross profit percentage (Gross profit / Net sales) | 60.1% | 58.8% |  |  |

---

Cost of sales during the fiscal year ended September 30, 2025 decreased as a percentage of net sales. This was primarily driven by the application of our three core value-driven operating strategy (obtaining profitable new business, continually improving our cost structure and providing highly engineered value-added products to customers) coupled with fixed overhead costs spread over higher production volume.

Foreign exchange rates continue to fluctuate; the loss is primarily attributable to the continued weakening of the U.S. dollar. Loss contract amortization fluctuates primarily based on the rate of actual to forecasted shipments of the products covered under the onerous contract.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* ***Selling and Administrative Expenses.*** Selling and administrative expenses decreased by $35 million to $945 million for the fiscal year ended September 30, 2025. The related percentage of net sales for the fiscal years ended September 30, 2025 and 2024 were as follows (amounts in millions):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Fiscal Years Ended** | **Fiscal Years Ended** | | |
| | **September 30, 2025** | **September 30, 2024** | **Change** | **% Change** |
| Selling and administrative expenses - excluding costs below | $779 | $738 | $41 | 5.6% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of net sales | 8.8% | 9.3% |  |  |
| Non-cash stock and deferred compensation expense | 142 | 196 | (54) | (27.6)% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of net sales | 1.6% | 2.5% |  |  |
| Acquisition transaction and integration-related expenses | 24 | 46 | (22) | (47.8)% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of net sales | 0.3% | 0.6% |  |  |
| Total selling and administrative expenses | $945 | $980 | $(35) | (3.6)% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;% of net sales | 10.7% | 12.3% |  |  |

---

The decrease in non-cash stock and deferred compensation expense is primarily attributable to the appreciation of the stock price at a higher rate in fiscal 2024 compared to fiscal 2025, as the stock price is a key input used to determine the Black-Scholes fair value for the non-cash stock compensation expense, and lower deferred compensation expense.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* ***Interest Expense-net.*** Interest expense-net includes interest on borrowings outstanding, amortization of debt issuance costs, original issue discount, revolving credit facility fees, finance leases, interest income and the impact of interest rate swaps, caps and collars designated and qualifying as cash flow hedges. Interest expense-net increased $286 million, or 22.2%, to $1,572 million for the fiscal year ended September 30, 2025 from $1,286 million for the fiscal year ended September 30, 2024. The increase in interest expense-net was primarily due to an increase in outstanding borrowings (refer to Note 10, "Debt" in the notes to the consolidated financial statements for information on our debt) and a decrease in interest income. The weighted average interest rate for cash interest payments on total borrowings outstanding was 6.3% for the fiscal years ended September 30, 2025 and September 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* ***Income Tax Provision.*** Income tax expense as a percentage of income before income taxes was approximately 21.1% for the fiscal year ended September 30, 2025 compared to 22.6% for the fiscal year ended September 30, 2024. Refer to Note 12, "Income Taxes", in the notes to the consolidated financial statements included herein for additional information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*•* ***Earnings per Share*.** Basic and diluted earnings per share was $32.08 for the fiscal year ended September 30, 2025 and $25.62 for the fiscal year ended September 30, 2024. Net income attributable to TD Group for the fiscal year ended September 30, 2025 of $2,074 million was decreased by dividend equivalents of $208 million, or $3.58 per share, resulting in net income applicable to TD Group common stockholders of $1,866 million. Net income attributable to TD Group for the fiscal year ended September 30, 2024 of $1,714 million was decreased by dividend equivalents of $233 million, or $4.02 per share, resulting in net income applicable to TD Group common stockholders of $1,481 million.

**<u>Business Segments</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ***Segment Net Sales*.** Net sales by segment for the fiscal years ended September 30, 2025 and 2024 were as follows (amounts in millions):

*Significant Transactions of Fiscal 2025 and Subsequent Events*

*Debt Financing*

During fiscal 2025, the Company completed approximately $11,000 million in debt financing transactions, inclusive of new issuances and refinancing of existing debt. Below is further information on the significant debt financing transactions occurring in fiscal 2025:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On May 20, 2025, the Company completed the issuance of $2,650 million in 6.375% senior subordinated notes due 2033 (the "6.375% 2033 Notes"), which the net proceeds of approximately $2,615 million, along with existing cash on hand, were used to redeem all of its outstanding $2,650 million in 5.500% senior subordinated notes due 2027 (the "5.500% 2027 Notes"). The redemption occurred on June 20, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On July 11, 2025, the Company amended its Securitization Facility to, among other things, (i) increase the borrowing capacity from $650 million to $725 million; and (ii) extend the maturity date to July 10, 2026 at an interest rate of Term SOFR plus 1.35% compared to an interest rate of Term SOFR plus 1.45% that applied prior to the amendment. Prior to the amendment, the Securitization Facility was fully drawn. As of September 30, 2025, the Securitization Facility was fully drawn as the remaining $75 million available was drawn in the fourth quarter of fiscal 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On August 19, 2025, the Company completed $5,000 million in new debt issuances. The new debt was comprised of the following: (i) $500 million in aggregate principal amount of senior secured notes due 2034 in a private offering at an issue price of 100% that bear interest at a rate of 6.250% (the "2034 Secured Notes"); (ii) $2,000 million in aggregate principal amount of senior subordinated notes due 2034 at an issue price of 100% that bear interest at a rate of 6.750% (the "6.750% 2034 Notes"); and (iii) $2,500 million of Tranche M term loans that bear interest at a rate of Term SOFR plus 2.50%. Original issue discount of 0.25%, or approximately $6 million, was paid to the lenders of the Tranche M term loans. The proceeds from the August 19, 2025 new debt issuances were used, along with existing cash on hand, to fund a $90.00 special dividend declaration on each outstanding share of common stock and cash dividend equivalent payments on eligible vested options outstanding under its stock option plans further described below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On September 17, 2025, the Company (i) repriced all of its $1,686 million in existing Tranche K term loans to bear interest at Term SOFR plus 2.25% compared to Term SOFR plus 2.75% applicable prior to the transaction; and (ii) amended and extended $1,857 million in existing Tranche I term loans maturing August 24, 2028 and converted such loans into new Tranche K term loans maturing March 22, 2030 (collectively, the "Tranche K term loans" referred to herein are comprised of the existing Tranche K term loans and new Tranche K term loans as described above).

*Acquisitions*

During fiscal 2025, the Company completed approximately $413 million in acquisitions of businesses, net of cash acquired, including the acquisition of Servotronics, Inc. ("Servotronics") completed on July 1, 2025 via a tender offer for approximately $133 million in cash. All fiscal 2025 acquisitions were financed using existing cash on hand.

On October 6, 2025, the Company completed the acquisition of all the outstanding stock of the Simmonds Precision Products, Inc. Business ("Simmonds") of Goodrich Corporation from RTX Corporation for approximately $757 million in cash. The acquisition was financed using existing cash on hand. The definitive agreement to acquire Simmonds was previously signed on June 30, 2025.

*Special Dividends*

On October 18, 2024, the Company paid a special cash dividend of $75.00 per outstanding share of common stock and cash dividend equivalent payments on eligible vested options outstanding under its stock option plans, which was authorized and declared in September 2024 (fiscal 2024). The total cash payment in October 2024 (fiscal 2025) of special dividend and dividend equivalents from this declaration, which was funded by a combination of (i) $3,000 million in new senior secured debt issued on September 19, 2024; and (ii) existing cash on hand, was approximately $4,216 million in special dividends and $132 million in cash dividend equivalent payments.

On August 20, 2025, the Company's Board of Directors authorized and declared a special cash dividend of $90.00 per outstanding share of common stock and cash dividend equivalent payments on eligible vested options outstanding under its stock option plans. The total cash payment in September 2025 of special dividend and dividend equivalents from this declaration, which was funded by a combination of (i) $5,000 million in new senior secured and unsecured debt issued on August 19, 2025 (as noted above); and (ii) existing cash on hand, was approximately $5,073 million in special dividends and $159 million in cash dividend equivalent payments.

*Common Stock Repurchases*

At various points in fiscal 2025, the Company repurchased, in aggregate, 401,036 shares of common stock at an average price of $1,246.71 per share for a total amount of $500 million.

In October 2025, the Company repurchased 79,959 shares of common stock at an average price of $1,249.90 per share for a total amount of $100 million. Whether the Company undertakes additional share repurchases or other aforementioned activities will depend on prevailing market conditions, the Company's liquidity requirements, contractual restrictions and other factors.

In November 2025, the Board of Directors authorized an additional $5,000 million in share repurchases of common stock permissible under the Company's existing stock repurchase program, subject to any restrictions specified in the Credit Agreement and indentures governing the existing Subordinated and Secured Notes.

\* \* \* \* \*

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.

The Company's ability to make scheduled interest payments on, or to refinance, the Company's indebtedness, or to fund non-acquisition related capital expenditures and research and development efforts, will depend on the Company's ability to generate cash in the future. This is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond its control.

The Company's objective is to maintain an allocation of at least 75% fixed rate and 25% variable rate debt thereby limiting its exposure to changes in near-term interest rates. Interest rate swaps, caps and collars used to hedge and offset, respectively, the variable interest rates on our term loans are further described in Note 18, "Derivatives and Hedging Activities," in the notes to the consolidated financial statements included herein. As of September 30, 2025, approximately 75% of our gross debt was fixed rate.

As of September 30, 2025, the Company has significant cash liquidity as illustrated in the table presented below (in millions):

---

| | |
|:---|:---|
| | **As of September 30, 2025** |
| Cash and cash equivalents | $2808 |
| Availability on revolving credit facility | 857 |
| Cash liquidity | $3665 |

---

We believe our significant cash liquidity will allow us to meet our anticipated funding requirements. We expect to meet our short-term cash liquidity requirements (including interest obligations and capital expenditures) through net cash from operating activities, cash on hand and, if needed, draws on the revolving credit facility. Long-term cash liquidity requirements consist primarily of obligations under our long-term debt agreements. There is no maturity on any tranche of term loans or notes until August 2028 (fiscal 2028).

The Company estimates its capital expenditures in fiscal year 2026 to be approximately 2.50% to 3.25% of net sales. The Company's capital expenditures incurred from year-to-year are funded using existing cash on hand and are primarily for projects that are consistent with our three core value-driven operating strategy (obtaining profitable new business, continually improving our cost structure and providing highly engineered value-added products to customers) such as automation projects.

------

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

In connection with the continued application of our three core value-driven operating strategy, we expect our efforts will continue to generate strong margins and provide 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 strategic business acquisitions, pay dividends to our shareholders and make opportunistic investments in our own stock, subject to any restrictions in our existing Credit Agreement and market conditions.

The Company may issue additional debt if prevailing market conditions are favorable to doing so. In addition, the Company may increase its borrowings in connection with acquisitions, if cash flow from operating activities becomes insufficient to fund current operations or for other short-term cash needs or for common stock repurchases or dividends. Our future leverage will also be impacted by the then current conditions of the credit markets.

*Operating Activities*. The Company generated $2,038 million of net cash from operating activities during fiscal 2025 compared to $2,045 million during fiscal 2024.

The change in trade accounts receivable during fiscal 2025 was a use of cash of $212 million compared to a use of cash of $84 million in fiscal 2024. The increase is primarily attributable to increased revenue. The Company actively manages its accounts receivable, the related agings and collection efforts.

The change in inventories during fiscal 2025 was a use of cash of $156 million compared to a use of cash of $104 million in fiscal 2024. The increase is due to an increase in raw materials to support the fiscal 2026 sales demand. The Company manages inventory levels in support of customer needs.

The change in accounts payable during fiscal 2025 was a source of cash of $38 million compared to a use of cash of $11 million in fiscal 2024. The change is due to the timing of payments to suppliers.

*Investing Activities.* Net cash used in investing activities was $595 million during fiscal 2025, consisting of $419 million from the acquisition of Servotronics and other acquisitions of businesses completed during fiscal 2025 and capital expenditures of $222 million; partially offset by other investing transactions, net, of $46 million.

Net cash used in investing activities was $2,441 million during fiscal 2024, consisting of $2,347 million from the acquisitions of Raptor Scientific, the Electron Device Business of Communications & Power Industries ("CPI's Electron Device Business") and other acquisitions of businesses completed during fiscal 2024 and capital expenditures of $165 million; partially offset by other investing transactions, net, of $71 million.

*Financing Activities*. Net cash used in financing activities was $4,900 million during fiscal 2025. The use of cash was primarily attributable to special dividend and dividend equivalent payments of $9,629 million plus repurchases of common stock of $500 million; partially offset by the net proceeds of short-term and long-term debt, including fees, of $5,063 million plus proceeds from stock option exercises of $166 million.

Net cash provided by financing activities was $3,171 million during fiscal 2024. The source of cash was primarily attributable to the net proceeds of short-term and long-term debt, including fees, of $4,965 million plus proceeds from stock option exercises of $245 million; partially offset by special dividend and dividend equivalent payments of $2,038 million.

*Description of Senior Secured Term Loans and Indentures*

*Senior Secured Term Loans Facility*

TransDigm has $11,124 million in fully drawn term loans under the Term Loans Facility as of September 30, 2025 and a $910 million revolving credit facility. The Term Loans Facility consists of four tranches of term loans (refer to Note 10, "Debt" in the notes to the consolidated financial statements for information on our term loans).

The Term Loans Facility requires quarterly aggregate principal payments of approximately $28 million. The revolving commitments consist of two tranches which include up to $139 million of multicurrency revolving commitments. At September 30, 2025, the Company had $53 million in letters of credit outstanding and $857 million in borrowings available under the revolving commitments. Draws on the revolving commitments are subject to an interest rate of 2.25%. The unused portion of the revolving commitments is subject to a fee of 0.50% per annum. The maturity date of the revolving credit facility is February 27, 2029.

The interest rates per annum applicable to the Term Loans Facility under the Credit Agreement are, at TransDigm's option, equal to either an alternate base rate or an adjusted Term SOFR for one, three or six-month interest periods chosen by TransDigm, in each case plus an applicable margin percentage. The adjusted Term SOFR related to the Term Loans Facility are not subject to a floor. Refer to Note 18, "Derivatives and Hedging Activities," in the notes to the consolidated financial statements included herein for information about how our interest rate swaps, cap and collar agreements are used to hedge and offset, respectively, the variable interest rate portion of our debt.

*Certain Restrictive Covenants in Our Debt Documents*

The Credit Agreement and the indentures governing the Subordinated Notes and Secured 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. 15, executed on March 22, 2024.

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 7.25x and the consolidated secured net debt ratio would be no greater than 5.00x, in each case, after giving effect to such incremental term loans or additional revolving commitments.

If any such default occurs, the lenders under the Credit Agreement and the holders of the Subordinated Notes and Secured 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 and the holders of the Secured Notes 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.

With the exception of the revolving credit facility, the Company has no maintenance covenants in its existing term loan and indenture agreements. Under the Credit Agreement, if the usage of the revolving credit facility exceeds 40% (or, currently, $364 million) of the total revolving commitments, the Company is required to maintain a maximum consolidated net leverage ratio of net debt to trailing four-quarter EBITDA As Defined of 7.50x (or, solely with respect to the first four fiscal quarters ending after the consummation of any material acquisition, 8.00x) as of the last day of the fiscal quarter.

As of September 30, 2025, the Company was in compliance with all of its debt covenants and expects to remain in compliance with its debt covenants in subsequent periods.

*Trade Receivable Securitization Facility*

The Company's 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.

On July 11, 2025, the Company amended the Securitization Facility to, among other things, (i) increase the borrowing capacity from $650 million to $725 million; and (ii) extend the maturity date to July 10, 2026 at an interest rate of Term SOFR plus 1.35% compared to an interest rate of Term SOFR plus 1.45% that applied prior to the amendment. Prior to the amendment, the Securitization Facility was fully drawn.

As of September 30, 2025, the Securitization Facility was fully drawn as the remaining $75 million available was drawn in the fourth quarter of fiscal 2025. At September 30, 2025, the applicable interest rate was 5.67%. The Securitization Facility is collateralized by substantially all of the Company's domestic operations' trade accounts receivable.

**Off-Balance Sheet Arrangements**

The Company utilizes letters of credit to back certain payment and performance obligations. Letters of credit are subject to limits based on amounts outstanding under the Company's revolving credit facility. As of September 30, 2025, the Company had $53 million in letters of credit outstanding.

**Critical Accounting Policies and Estimates**

Our consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States ("U.S. GAAP"), which often requires the judgment of management in the selection and application of certain accounting principles and methods. Management believes that the quality and reasonableness of our most critical policies enable the fair presentation of our financial position and results of operations. However, investors are cautioned that the sensitivity of financial statements to these methods, assumptions and estimates could create materially different results under different conditions or using different assumptions.

Below are those policies applied in preparing our financial statements that management believes are the most dependent on the application of estimates and assumptions. For additional significant accounting policies, see Note 1, "Summary of Significant Accounting Policies," in the notes to the consolidated financial statements included herein.

------

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

***Revenue Recognition*** – The Company recognizes revenue from contracts with customers using the five step model prescribed in ASC 606. A substantial portion of the Company's revenue is recorded at a point in time. Revenue is recognized from the sale of products or services when obligations under the terms of the contract are satisfied and control of promised goods or services have transferred to the customer. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services. Revenue is measured at the amount of consideration the Company expects to be paid in exchange for goods or services. In a limited number of contracts, control transfers to the customer over time, primarily in contracts where the customer is required to pay for the cost of both the finished and unfinished goods at the time of cancellation plus a reasonable profit relative to the work performed for products that were customized for the customer. Therefore, we recognize revenue over time for those agreements that have a right to margin and where the products being produced have no alternative use. For agreements with multiple performance obligations, judgment is required to determine whether performance obligations specified in these agreements are distinct and should be accounted for as separate revenue transactions for recognition purposes based on the standalone selling price of each performance obligation. The primary method used to estimate a standalone selling price is the price observed in standalone sales to customers for the same product or service. We consider the contractual consideration payable by the customer and assesses variable consideration that may affect the total transaction price. Variable consideration is included in the estimated transaction price when there is a basis to reasonably estimate the amount, including whether the estimate should be constrained in order to avoid a significant reversal of revenue in a future period. These estimates are based on historical experience, anticipated performance under the terms of the contract and our best judgment at the time.

***Goodwill and Other Intangible Assets*** – In accordance with ASC 805, "Business Combinations," the Company uses the acquisition method of accounting to allocate costs of acquired businesses to the assets acquired and liabilities assumed based on their estimated fair values at the dates of acquisition. The excess costs of acquired businesses over the fair values of the assets acquired and liabilities assumed are recognized as goodwill. The valuations of the acquired assets and liabilities will impact the determination of future operating results. Determining the fair value of assets acquired and liabilities assumed requires management's judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, revenue growth rates and earnings before interest, taxes, depreciation and amortization ("EBITDA") margins, discount rates, customer attrition rates, royalty rates, asset lives and market multiples, among other items. We determine the fair values of intangible assets acquired generally in consultation with third-party valuation advisors. Fair value adjustments to the Company's assets and liabilities are recognized and the results of operations of the acquired business are included in our consolidated financial statements from the effective date of the merger or acquisition.

Intangible assets other than goodwill are recognized if the benefit of the intangible asset is obtained through contractual or other legal rights, or if the intangible asset can be sold, transferred, licensed or exchanged, regardless of the Company's intent to do so. Goodwill and identifiable intangible assets are recorded at their estimated fair value on the date of acquisition and are reviewed at least annually for impairment based on cash flow projections and fair value estimates.

U.S. GAAP requires that the annual, and any interim, goodwill impairment assessment be performed at the reporting unit level. Our reporting units have been identified at the operating unit level, which is one level below our operating segments. Substantially all goodwill was determined and recognized for each reporting unit pursuant to the accounting for the merger or acquisition as of the date of each transaction. With respect to acquisitions integrated into an existing reporting unit, any acquired goodwill is combined with the goodwill of the reporting unit.

Companies may perform a qualitative assessment as the initial step in the annual goodwill impairment testing process for all or selected reporting units. Companies are also allowed to bypass the qualitative analysis and perform a quantitative analysis if desired. Economic uncertainties and the length of time from the calculation of a baseline fair value are factors that we consider in determining whether to perform a quantitative test.

When we evaluate the potential for goodwill impairment using a qualitative assessment, we consider factors including, but not limited to, macroeconomic conditions, industry conditions, the competitive environment, changes in the market for our products and services, regulatory and political developments, entity specific factors such as strategy and changes in key personnel and overall financial performance. If, after completing this assessment, it is determined that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value, we proceed to a quantitative impairment test. For the quantitative test, management determines the estimated fair value through the use of a discounted cash flow valuation model incorporating discount rates commensurate with the risks involved for each reporting unit. If the estimated fair value of the reporting unit is less than the current carrying value, impairment of goodwill of the reporting unit is recognized. The key assumptions used in the discounted cash flow valuation model for impairment testing includes discount rates, revenue growth rates and EBITDA margins, cash flow projections and terminal value rates. Discount rates are set by using the weighted average cost of capital ("WACC") methodology. The WACC methodology considers market and industry data in determining the appropriate discount rates to be used, inclusive of company-specific risk factors. The Company utilizes a third party valuation firm to assist in the determination of the WACC. The discount rate utilized for each reporting unit is indicative of the return an investor would expect to receive for investing in such a business.

------

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

Management, considering industry and company-specific historical and projected data, develops growth rates, sales projections and cash flow projections for each reporting unit. Terminal value rate determination follows a common methodology of capturing the present value of perpetual cash flow estimates beyond the last projected period assuming a constant WACC and low long-term growth rates.

The impairment test for indefinite-lived intangible assets consists of a comparison between the estimated fair values and carrying values. If the carrying amounts of intangible assets that have indefinite useful lives exceed their estimated fair values, an impairment loss will be recognized in an amount equal to the difference. Management utilizes the royalty savings valuation method to determine the estimated fair value for each indefinite-lived intangible asset. In this method, management estimates the royalty savings arising from the ownership of the intangible asset. The key assumptions used in estimating the royalty savings for impairment testing include discount rates, royalty rates, growth rates, sales projections and terminal value rates. Discount rates used are similar to the rates developed by the WACC methodology, inclusive of considering any differences in company-specific risk factors between reporting units and the indefinite-lived intangible assets. Royalty rates are established by management with the advice of valuation experts. Management, considering industry and company-specific historical and projected data, develops growth rates and sales projections for each significant intangible asset. Terminal value rate determination follows common methodology of capturing the present value of perpetual sales estimates beyond the last projected period assuming a constant WACC and low long-term growth rates.

The discounted cash flow and royalty savings valuation methodologies require management to make certain assumptions based upon information available at the time the valuations are performed. Actual results could differ from these assumptions. Management believes the assumptions used are reflective of what a market participant would have used in calculating fair value considering the current economic conditions.

As of the first day of the fourth quarter of fiscal 2025, the date of the annual impairment test, no indefinite-lived intangible assets or goodwill was determined to be impaired. As economic and market conditions have not changed significantly since the first day of the fourth quarter, this conclusion remains appropriate as of September 30, 2025.

***Income Taxes*** – The Company estimates income taxes in each jurisdiction in which it operates. This involves estimating taxable earnings, specific taxable and deductible items, the likelihood of generating sufficient future taxable income to utilize deferred tax assets and possible exposures related to future tax audits. To the extent these estimates change, adjustments to deferred and accrued income taxes are made in the period in which the changes occur. Historically, such adjustments have not been significant.

**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 U.S. 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 U.S. GAAP. Some of these limitations are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• neither EBITDA nor EBITDA As Defined reflects the significant interest expense, or the cash requirements, necessary to service interest payments on our indebtedness;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the omission of the substantial amortization expense associated with our intangible assets further limits the usefulness of EBITDA and EBITDA As Defined;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• neither EBITDA nor EBITDA As Defined includes the payment of taxes, which is a necessary element of our operations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 U.S. 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 U.S. GAAP, and neither should be considered as an alternative to net income or cash flow from operations determined in accordance with U.S. GAAP. Our calculation of EBITDA and EBITDA As Defined may not be comparable to the calculation of similarly titled measures reported by other companies.

**ITEM 7A.&nbsp;&nbsp;&nbsp;&nbsp;QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

*Interest Rate Risk*

At September 30, 2025, we had borrowings under our Term Loans Facility, which consists of four tranches of term loans of approximately $11,124 million, as well as $725 million from the Securitization Facility, that are subject to interest rate risk, particularly movements in Term SOFR. Borrowings under our term loans bear interest, at our option, at a rate equal to either an alternate base rate or an adjusted Term SOFR for a one-, three- or six-month thereafter (in each case, subject to the availability thereof), interest period chosen by us, in each case, plus an applicable margin percentage. Our Securitization Facility bears interest at a rate of three-month Term SOFR plus 1.35%. Accordingly, the Company's cash flows and earnings will be exposed to the market risk of interest rate changes resulting from variable rate borrowings under our term loans. The Company's objective is to maintain an allocation of at least 75% fixed rate and 25% variable rate debt thereby limiting its exposure to changes in near-term interest rates. Interest rate swaps, caps and collars used to hedge and offset, respectively, the variable interest rates on the credit facility are described in Note 18, "Derivatives and Hedging Activities," in the notes to the consolidated financial statements included herein. We do not hold or issue derivative instruments for speculative purposes. As of September 30, 2025, approximately 75% of our gross debt was fixed rate. The effect of a hypothetical one percentage point increase in interest rates would increase the annual interest costs under our Term Loans Facility and Securitization Facility by approximately $57 million based on the amount of outstanding borrowings at September 30, 2025. The weighted average interest rate on the $11,124 million of the term loans and the $725 million drawn on the Securitization Facility at September 30, 2025 was approximately 6.3%.

For information about the fair value of the aggregate principal amount of borrowings under our term loans and the fair value of the senior secured and subordinated notes, refer to Note 11, "Fair Value Measurements," in the notes to the consolidated financial statements included herein.

*Foreign Currency Risk*

Certain of our foreign subsidiaries' sales and results of operations are subject to the impact of foreign currency fluctuations, primarily the British pound and the euro. Because our consolidated financial statements are presented in U.S. dollars, increases or decreases in the value of the U.S. dollar relative to other currencies in which we transact business could materially adversely affect our net sales, net income and the carrying values of our assets located outside the U.S. Foreign currency forward exchange contracts provide for the purchase or sale of foreign currencies at specified future dates at specified exchange rates, and are used to offset changes in the fair value of certain assets or liabilities or forecasted cash flows resulting from transactions denominated in foreign currencies. The foreign currency forward exchange contracts entered into by the Company are described in Note 18, "Derivatives and Hedging Activities," in the notes to the consolidated financial statements included herein. A 10% change in foreign currency exchange rates would not have resulted in a material impact to net income for the fiscal year ended September 30, 2025.

**ITEM 9A.&nbsp;&nbsp;&nbsp;&nbsp;CONTROLS AND PROCEDURES**

**Evaluation of Disclosure Controls and Procedures**

As of September 30, 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.

**Management's Report on Internal Control Over Financial Reporting**

The management of TD Group is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rule 13a-15(f). Using criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) ("COSO") in Internal Control-Integrated Framework, TransDigm's management assessed the effectiveness of the Company's internal control over financial reporting as of September 30, 2025. Based on our assessment, management concluded that the Company's internal control over financial reporting was effective as of September 30, 2025.

The effectiveness of the Company's internal control over financial reporting as of September 30, 2025 has been audited by Ernst & Young LLP, an independent registered public accounting firm, as stated in their report, which is included elsewhere in this Annual Report on Form 10-K and is incorporated herein by reference.

**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 fourth quarter of fiscal 2025 that materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.

**Report of Independent Registered Public Accounting Firm**

To the Stockholders and the Board of Directors of

TransDigm Group Incorporated

**Opinion on Internal Control over Financial Reporting**

We have audited TransDigm Group Incorporated's internal control over financial reporting as of September 30, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the "COSO criteria"). In our opinion, TransDigm Group Incorporated (the "Company") maintained, in all material respects, effective internal control over financial reporting as of September 30, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the consolidated balance sheets of the Company as of September 30, 2025 and 2024, the related consolidated statements of income, comprehensive income, changes in stockholders' deficit and cash flows for each of the three fiscal years in the period ended September 30, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a) and our report dated November 12, 2025 expressed an unqualified opinion thereon.

**Basis for Opinion**

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**Definition and Limitations of Internal Control Over Financial Reporting**

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

**Report of Independent Registered Public Accounting Firm**

To the Stockholders and the Board of Directors of

TransDigm Group Incorporated

**Opinion on the Financial Statements** 

We have audited the accompanying consolidated balance sheets of TransDigm Group Incorporated (the "Company") as of September 30, 2025 and 2024, the related consolidated statements of income, comprehensive income, changes in stockholders' deficit and cash flows for each of the three fiscal years in the period ended September 30, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a) (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at September 30, 2025 and 2024, and the results of its operations and its cash flows for each of the three fiscal years in the period ended September 30, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) ("PCAOB"), the Company's internal control over financial reporting as of September 30, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated November 12, 2025 expressed an unqualified opinion thereon.

**Basis for Opinion**

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matter**

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

| | ***Annual assessment of goodwill for impairment*** |
| *Description of the Matter* | As disclosed in Note 8, the Company had goodwill of $10,612 million at September 30, 2025. As discussed in Note 1 to the consolidated financial statements, goodwill is tested for impairment annually as of the first day of the fourth fiscal quarter, or more frequently, if an event occurs or circumstances change that would more likely than not reduce fair value below carrying value. The Company's goodwill is initially assigned to its reporting units as of the acquisition date. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the Company determines the qualitative assessment is not sufficient to conclude on whether it is more likely than not that the fair value is less than the carrying value, a quantitative impairment test is performed. The Company may also elect to bypass the qualitative assessment and perform a quantitative test for any or all reporting units. As part of the quantitative assessment, the Company determines the fair value of the reporting units using a discounted cash flow valuation model.<br>Auditing management's quantitative impairment assessment was complex and judgmental for certain of the reporting units due to the significant estimation required to determine fair value. In particular, the fair value estimates were sensitive to significant assumptions, such as changes in the discount rate, revenue growth rates and EBITDA margins, which are affected by expectations about future market or economic conditions. |
| *How We Addressed the Matter in Our Audit* | We obtained an understanding, evaluated the design and tested the operating effectiveness of controls over the Company's impairment process, including controls over management's review of the valuation model and the significant assumptions underlying the fair value determination, as described above.<br>To test the fair values of the Company's reporting units, our audit procedures included, among others, assessing the use of the discounted cash flow valuation model and testing the significant assumptions discussed above and underlying data used by the Company in its analyses for certain of the reporting units evaluated using the quantitative assessment. We utilized internal valuation specialists in assessing the fair value methodologies applied and evaluating the reasonableness of the discount rate selected by management in the determination of the fair values of certain of the reporting units. We compared the revenue growth rates and EBITDA margins used by management to current industry and economic trends, recent historical performance, or other relevant factors. We performed sensitivity analyses of significant assumptions described above to evaluate the changes in fair values that would result from changes in the assumptions. |

**TRANSDIGM GROUP INCORPORATED**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**FISCAL YEARS ENDED SEPTEMBER 30, 2025, 2024 AND 2023**

**1.&nbsp;&nbsp;&nbsp;&nbsp;SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

*<u>General Information</u>*

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 that are critical to the safe and effective operation of nearly all commercial and military aircraft worldwide. Our products are represented in 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 products. 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."

As used in this Annual Report on Form 10-K, unless the context otherwise requires, the terms "Company", "TD Group", "TransDigm", "we," "our" or "us" refer to TransDigm Group Incorporated and its subsidiaries.

*<u>Basis of Presentation and Principles of Consolidation</u>*

The accompanying consolidated financial statements were prepared in conformity with generally accepted accounting principles in the United States ("U.S. GAAP") and include the accounts of TD Group and subsidiaries. Intercompany balances and transactions have been eliminated. Certain reclassifications to the consolidated financial statements and notes have been made to the prior year amounts to conform to the current year presentation, none of which are material.

***Estimates*** – The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

***Revenue Recognition*** – The Company recognizes revenue from contracts with customers using the five step model prescribed in ASC 606. A substantial portion of the Company's revenue is recorded at a point in time basis. Revenue is recognized from the sale of products or services when obligations under the terms of the contract are satisfied and control of promised goods or services have transferred to the customer. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services. Revenue is measured at the amount of consideration the Company expects to be paid in exchange for goods or services. Refer to Note 3, "Revenue Recognition," for further information.

***Shipping and Handling Costs*** – Shipping and handling costs are included in cost of sales in the consolidated statements of income.

***Research and Development Costs*** – The Company expenses research and development costs as incurred and classifies such amounts in selling and administrative expenses. The expense recognized for research and development costs for the fiscal years ended September 30, 2025, 2024 and 2023 was approximately $118 million, $107 million, and $105 million, respectively.

***Cash Equivalents*** – The Company considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Cash equivalents are recorded at cost, which approximates fair value.

***Allowance for Credit Losses*** – The Company's allowance for credit losses is the allowance for uncollectible accounts. The allowance for uncollectible accounts reduces the trade accounts receivable balance to the estimated net realizable value equal to the amount that is expected to be collected. The Company's method for developing its allowance for credit losses is based on historical write-off experience, the aging of receivables, an assessment of the creditworthiness of customers, economic conditions and other external market information. The allowance also incorporates a provision for the estimated impact of disputes with customers. All provisions for allowances for uncollectible accounts are included in selling and administrative expenses. The determination of the amount of the allowance for uncollectible accounts is subject to judgment and estimation by management and is also assessed individually at each operating unit by the operating unit's management team. If circumstances change or economic conditions deteriorate or improve, the allowance for uncollectible accounts could increase or decrease. Refer to Note 5, "Trade Accounts Receivable," for further information.

***Inventories*** – Inventories are stated at the lower of cost or net realizable value. Cost of inventories is generally determined by the average actual cost and the first-in, first-out ("FIFO") methods and includes material, labor and overhead related to the manufacturing process. Provision for potentially obsolete or slow-moving inventory is made based on management's analysis of inventory levels, historical usage and future sales forecasts. Refer to Note 6, "Inventories," for further information.

------

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

***Property, Plant and Equipment*** – Property, plant and equipment are stated at cost and include improvements which significantly increase capacities or extend the useful lives of existing plant and equipment. Depreciation is computed using the straight-line method over the following general estimated useful lives: land improvements from 10 to 20 years, buildings and improvements from 5 to 30 years, machinery and equipment from 2 to 10 years and furniture and fixtures from 3 to 10 years. Certain exceptions do apply in which an asset will have an estimated useful life outside of the range listed above dependent on, among other things, the nature and condition of the asset. Net gains or losses related to asset dispositions are recognized in earnings in the period in which dispositions occur. Routine maintenance, repairs and replacements are expensed as incurred. Amortization expense of assets accounted for as finance leases is included within depreciation expense.

Property, plant and equipment is assessed for potential impairment whenever indicators of impairment are present by determining whether the carrying value of the property can be recovered through projected, undiscounted cash flows from future operations over the property's remaining estimated useful life. Any impairment recognized is the amount by which the carrying amount exceeds the fair value of the asset. Fair value is measured based on quoted market prices in active markets, if available. If quoted market prices are not available, the estimate of fair value is based on various valuation techniques, including the discounted value of estimated future cash flows. No material impairments of long-lived assets were recorded in fiscal 2025, 2024 or 2023. Refer to Note 7, "Property, Plant and Equipment," for further information.

***Financial Instruments*** – Interest rate swap, cap and collar agreements are used to manage interest rate risk associated with floating rate borrowings under our Second Amended and Restated Credit Agreement dated as of June 4, 2014 (the "Credit Agreement"). 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. The 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 from the effective date through the maturity date of the respective interest rate swap, cap and collar agreements, thereby reducing the impact of interest rate movements on future interest expense. These derivative instruments qualify as effective cash flow hedges under U.S. GAAP.

The Company transacts business in various foreign currencies, which subjects the Company's cash flows and results of operations to exposure related to changes in foreign currency exchange rates. These exposures arise primarily from purchases or sales of products and services from third parties. Foreign currency forward exchange contracts provide for the purchase or sale of foreign currencies at specified future dates at specified exchange rates, and are used to offset changes in the fair value of certain assets or liabilities or forecasted cash flows resulting from transactions denominated in foreign currencies.

For the interest rate swap, cap and collar agreements and the foreign currency forward contracts designated as cash flow hedges, the effective portion of the gain or loss from the financial instruments is 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, cap and collar 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 consolidated statements of income. As the foreign currency forward exchange contracts are used to manage foreign currency exposure primarily arising from sales to third parties, any gains or losses from the derivative instruments that are reclassified into earnings are recognized in net sales in the consolidated statements of income. The cash flows from settled contracts are recognized in net cash provided by operating activities in the consolidated statements of cash flows. Refer to Note 18, "Derivatives and Hedging Activities," for further information.

***Business Combinations*** – In accordance with ASC 805, "Business Combinations," the Company uses the acquisition method of accounting to allocate costs of acquired businesses to the assets acquired and liabilities assumed based on their estimated fair values at the dates of acquisition. The excess costs of acquired businesses over the fair values of the assets acquired and liabilities assumed were recognized as goodwill. The valuations of the acquired assets and liabilities assumed will impact the determination of future operating results. Determining the fair value of assets acquired and liabilities assumed requires management's judgment and often involves the use of estimates and assumptions which may be significant, including assumptions with respect to future cash inflows and outflows, revenue growth rates and earnings before interest, taxes, depreciation and amortization ("EBITDA") margins, discount rates, customer attrition rates, royalty rates, asset lives and market multiples, among other items. These assumptions are forward looking and could be affected by future economic and market conditions. We determine the fair values of intangible assets acquired generally in consultation with third-party valuation advisors. Fair value adjustments to the Company's assets and liabilities are recognized and the results of operations of the acquired business are included in our consolidated financial statements from the effective date of the merger or acquisition. Intangible assets other than goodwill are recognized if the benefit of the intangible asset is obtained through contractual or other legal rights, or if the intangible asset can be sold, transferred, licensed or exchanged, regardless of the Company's intent to do so.

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

Goodwill is the excess of the purchase price paid over the estimated fair value of the net assets of a business acquired. Other intangible assets consist of identifiable intangibles acquired or recognized in accounting for the acquisitions (trademarks, trade names, technology, customer relationships, order backlog and other intangible assets). Goodwill and intangible assets that have indefinite useful lives (i.e., trademarks and trade names) are subject to annual impairment testing or when indicators are present. Management determines fair value using a discounted future cash flow analysis or other accepted valuation techniques. Acquisition transaction-related expenses for the fiscal years ended September 30, 2025, 2024 and 2023 totaled approximately $6 million, $33 million and $6 million, respectively. These costs are expensed when incurred and included in selling and administrative expenses in the consolidated statements of income.

***Goodwill and Other Intangible Assets*** – The Company performs an annual impairment test for goodwill and other intangible assets as of the first day of the fourth fiscal quarter of each year, or more frequently, if an event occurs or circumstances change that would more likely than not reduce fair value below carrying value.

We may elect to perform a qualitative assessment that considers economic, industry and company-specific factors for all or selected reporting units. If, after completing this assessment, it is determined that it is more-likely-than-not that the fair value of a reporting unit is less than its carrying value, we proceed to a quantitative test. We may also elect to perform a quantitative test instead of a qualitative assessment for any or all of our reporting units. In this application, the definition of "more-likely-than-not" is interpreted as a likelihood of more than 50%. For the quantitative test, management determines the estimated fair value through the use of a discounted cash flow valuation model incorporating discount rates commensurate with the risks involved for each reporting unit. If the estimated fair value of the reporting unit is less than the current carrying value, impairment of goodwill of the reporting unit is recognized. The assumptions used in the discounted cash flow valuation model for impairment testing includes discount rates, revenue growth rates and EBITDA margins, cash flow projections and terminal value rates. Discount rates are set by using the weighted average cost of capital ("WACC") methodology.

U.S. GAAP requires that the annual, and any interim, impairment assessment be performed at the reporting unit level. Our reporting units have been identified at the operating unit level, which is one level below our operating segments. Substantially all goodwill was determined and recognized for each reporting unit pursuant to the accounting for the merger or acquisition as of the date of each transaction. With respect to acquisitions integrated into an existing reporting unit, any acquired goodwill is combined with the goodwill of the reporting unit.

The impairment test for indefinite lived intangible assets consists of a comparison between their fair values and carrying values. If the carrying amounts of intangible assets that have indefinite useful lives exceed their fair values, an impairment loss will be recognized in an amount equal to the sum of any such excesses.

As of the first day of the fourth quarter of fiscal 2025, the date of the annual impairment test, no indefinite-lived intangible assets or goodwill was determined to be impaired. As economic and market conditions have not changed significantly since the first day of the fourth quarter, this conclusion remains appropriate as of September 30, 2025.

The Company assesses the recoverability of its amortizable intangible assets only when indicators of impairment are present by determining whether the carrying value can be recovered through projected, undiscounted cash flows from future operations over their remaining lives. Amortization of amortizable intangible assets is computed using the straight-line method over the following general estimated useful lives: technology & other from 10 to 22 years, order backlog from 1 to 3 years, customer relationships from 10 to 20 years, and other intangible assets over 20 years. No indicators of impairment on the amortizable intangible assets were identified in fiscal 2025, 2024 or 2023.

***Stock-Based Compensation*** – The Company records stock-based compensation expense using the Black-Scholes pricing model based on certain valuation assumptions. Compensation expense is recorded over the vesting periods of the stock options, adjusted for expected forfeitures. The Company has classified stock-based compensation primarily within selling and administrative expenses to correspond with the classification of employees that receive stock option grants. The Company also evaluates any subsequent changes to the respective option holders terms under the modification rules of ASC 718. If determined to be a modification, the Black-Scholes pricing model is updated as of the date of the modification resulting in a cumulative catch up to expense, if necessary. Refer to Note 16, "Stock-Based Compensation," for further information.

------

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

***Income Taxes*** – The provision for income taxes is calculated using the asset and liability method. Under the asset and liability method, deferred income taxes are recognized for the tax effect of temporary differences between the financial statement carrying amount of assets and liabilities and the amounts used for income tax purposes and for certain changes in valuation allowances. Valuation allowances are recorded to reduce certain deferred tax assets when, in our estimation, it is more likely than not that a tax benefit will not be realized. We recognize uncertain tax positions when we have determined it is more likely than not that a tax position will be sustained upon examination. However, new information may become available, or applicable laws or regulations may change, thereby resulting in a favorable or unfavorable adjustment to amounts recorded. Taxes related to Global Intangible Low-Taxed Income ("GILTI") are treated as a current period expense when incurred. Refer to Note 12, "Income Taxes," for further information.

***Comprehensive Income (Loss)*** – The term "comprehensive income (loss)" represents the change in stockholders' equity (deficit) from transactions and other events and circumstances resulting from non-stockholder sources. The Company's accumulated other comprehensive income or loss, consisting principally of fair value adjustments to its interest rate swap, cap and collar agreements (net of tax), cumulative foreign currency translation adjustments and pension liability adjustments (net of tax), is reported separately in the accompanying consolidated statements of comprehensive income.

***Foreign Currency Translation and Transactions*** – The assets and liabilities of subsidiaries located outside the United States are translated into U.S. dollars at the rates of exchange in effect at the balance sheet dates. Revenue and expense items are translated at the average monthly exchange rates prevailing during the period. Gains and losses resulting from foreign currency transactions are recognized currently in income and those resulting from translation of financial statements, including gains and losses from certain intercompany transactions, are accumulated as a separate component of other comprehensive income (loss) for the period. Foreign currency losses or (gains) recognized in cost of sales on the consolidated statements of income from changes in exchange rates were $10 million, $20 million and $14 million for the fiscal years ended September 30, 2025, 2024 and 2023, respectively.

***Earnings per Share*** – Earnings per share information is determined using the two-class method, which includes the weighted-average number of common shares outstanding during the period and other securities that participate in cash dividends ("participating securities"). Our vested stock options are considered "participating securities" because they include non-forfeitable rights to cash dividends. In applying the two-class method, earnings are allocated to both common shares and participating securities based on their respective weighted-average shares outstanding for the period. Diluted earnings per share information may include the additional effect of other securities, if dilutive, in which case the dilutive effect of such securities is calculated using the treasury stock method. Contingently issuable shares are not included in earnings per share until the period in which the contingency is satisfied. Refer to Note 4, "Earnings Per Share," for further information.

*<u>New Accounting Pronouncements Adopted</u>*

In November 2023, the FASB issued ASU 2023-07, "Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures." ASU 2023-07 expands disclosures about a public business entity's reportable segments and provides for more detailed information about a reportable segment's expenses. Additionally, ASU 2023-07 requires all segment profit or loss and assets disclosures to be provided on an annual and interim basis. This standard is effective for annual periods beginning after December 15, 2023 (fiscal 2025) and interim periods within fiscal years beginning one year later (fiscal 2026). The Company adopted this standard in the fourth quarter of fiscal 2025. Refer to Note 15, "Segments," for further information.

*<u>New Accounting Pronouncements Issued</u>*

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures," which requires a public business entity to disclose specific categories in its annual effective tax rate reconciliation and disaggregated information about significant reconciling items by jurisdiction and by nature. The ASU also requires entities to disclose their income tax payments (net of refunds) to international, federal, and state and local jurisdictions. The standard makes several other changes to income tax disclosure requirements. This standard is effective for annual periods beginning after December 15, 2024 (fiscal 2026), and requires prospective application with the option to apply it retrospectively. Early adoption is permitted. The Company is currently evaluating this standard to determine its impact on our disclosures and believe that the adoption will not have a material impact on the consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU 2024-03, "Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): *Disaggregation of Income Statement Expenses*." Additionally, in January 2025, the FASB issued ASU 2025-01 to clarify the effective date of ASU 2024-03. The standard requires, among other items, additional disaggregated disclosures in the notes to financial statements for certain categories of expenses that are included on the face of the statement of income. The standard is effective for fiscal years beginning after December 15, 2026 (fiscal 2028), and for interim periods within fiscal years beginning after December 15, 2027 (fiscal 2029), on a retrospective or prospective basis, with early adoption permitted. The Company is currently evaluating this standard to determine its impact on our disclosures.

**2.&nbsp;&nbsp;&nbsp;&nbsp;ACQUISITIONS**

***Simmonds Precision Products, Inc. –*** On June 30, 2025, the Company entered into a definitive agreement to acquire all the outstanding stock of the Simmonds Precision Products, Inc.

------

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

***Other Acquisitions*** – For the fiscal year ended September 30, 2025, the Company completed a number of acquisitions consisting of substantially all of the assets and technical data rights of certain product lines or all the outstanding stock of certain businesses (collectively, referred to herein as the "Other Acquisitions"), each meeting the definition of a business, for a total aggregate purchase price of $285 million in cash. Each of the acquisitions was financed through existing cash on hand. The operating results of the acquisitions, which represent bolt-ons to existing TransDigm operating units, are presented within TransDigm's Power & Control or Airframe segment. The Company expects that all of the $126 million of goodwill and $90 million of other intangible assets recognized as of September 30, 2025 for the acquisitions will be deductible for tax purposes over 15 years. As of September 30, 2025, the measurement period (not to exceed one year) is open for certain Other Acquisitions; therefore, the assets acquired and liabilities assumed are subject to adjustment until the end of the respective measurement period.

For the fiscal year ended September 30, 2024, the Company completed a number of Other Acquisitions for a total aggregate purchase price of $314 million in cash. Each of the acquisitions was financed through existing cash on hand. The operating results of the acquisitions, which represent bolt-ons to existing TransDigm operating units, are presented within TransDigm's Power & Control or Airframe segment. Of the $182 million of goodwill recognized for the acquisitions, $49 million is deductible for tax purposes over 15 years. Of the $116 million of other intangible assets recognized for the acquisitions, $22 million is deductible for tax purposes over 15 years.

Pro forma net sales and results of operations for the acquisitions, had they occurred at the beginning of the fiscal years ended September 30, 2025 or September 30, 2024 are not material and, accordingly, are not provided.

The acquisitions completed by the Company 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 strategy (obtaining profitable new business, continually improving our cost structure, and providing highly engineered value-added products to customers). The purchase prices paid reflect the current EBITDA As Defined and cash flows, as well as the future EBITDA As Defined and cash flows expected to be generated by the businesses, 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.

**3.&nbsp;&nbsp;&nbsp;&nbsp;REVENUE RECOGNITION**

TransDigm's sales are concentrated in the aerospace and defense industry. The Company's customers include: distributors of aerospace components, commercial airlines, large commercial transport and regional and business aircraft original equipment manufacturers ("OEMs"), various armed forces of the U.S. and friendly foreign governments, defense OEMs, system suppliers, and various other industrial customers.

The Company recognizes revenue from contracts with customers using the five step model prescribed in ASC 606. A substantial portion of the Company's revenue is recorded at a point in time basis. Revenue is recognized from the sale of products or services when obligations under the terms of the contract are satisfied and control of promised goods or services have transferred to the customer. Control is transferred when the customer has the ability to direct the use of and obtain benefits from the goods or services. Revenue is measured at the amount of consideration the Company expects to be paid in exchange for goods or services.

In a limited number of contracts, control transfers to the customer over time, primarily in contracts where the customer is required to pay for the cost of both the finished and unfinished goods at the time of cancellation plus a reasonable profit relative to the work performed for products that were customized for the customer. Therefore, we recognize revenue over time for those agreements that have a right to margin and where the products being produced have no alternative use.

Based on our production cycle, it is generally expected that goods related to the revenue will be shipped and billed within twelve months. For revenue recognized over time, we estimate the amount of revenue attributable to a contract earned at a given point during the production cycle based on certain costs, such as materials and labor incurred to date, plus the expected profit, which is a cost-to-cost input method.

We consider the contractual consideration payable by the customer and assess variable consideration that may affect the total transaction price. Variable consideration is included in the estimated transaction price when there is a basis to reasonably estimate the amount, including whether the estimate should be constrained in order to avoid a significant reversal of revenue in a future period. These estimates are based on historical experience, anticipated performance under the terms of the contract and our best judgment at the time.

------

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

When contracts are modified to account for changes in contract specifications and requirements, the Company considers whether the modification either creates new or changes the existing enforceable rights and obligations. Contract modifications that are for goods or services that are not distinct from the existing contract, due to the significant integration with the original good or service provided, are accounted for as if they were part of that existing contract. The effect of a contract modification to an existing contract on the transaction price and our measure of progress for the performance obligation to which it relates, is recognized as an adjustment to revenue on a cumulative catch-up basis. When the modifications include additional performance obligations that are distinct and at relative stand-alone selling price, they are accounted for as a new contract and performance obligation, which are recognized prospectively.

The Company's payment terms vary by the type and location of the customer and the products or services offered. The Company does not offer any payment terms that would meet the requirements for consideration as a significant financing component.

Shipping and handling fees and costs incurred in connection with products sold are recorded in cost of sales in the consolidated statements of income, and are not considered a performance obligation to our customers.

The Company pays sales commissions that relate to contracts for products or services that are satisfied at a point in time or over a period of one year or less and are expensed as incurred. These costs are reported as a component of selling and administrative expenses in the consolidated statements of income.

In fiscal 2025, 2024 and 2023, no customer individually accounted for 10% or more of the Company's net sales.

Net sales to foreign customers, primarily in Western Europe, Canada and Asia, were $3,296 million, $2,908 million and $2,320 million during the fiscal years ended September 30, 2025, 2024 and 2023, respectively.

We have elected to adopt the practical expedient to not disclose the aggregate amount of transaction price allocated to performance obligations that are unsatisfied as of the end of the reporting period for performance obligations that are part of a contract with an original expected duration of one year or less.

***Contract Assets and Liabilities*** – Contract assets reflect revenue recognized and performance obligations satisfied in advance of customer billing or reimbursable costs related to a specific contract. Contract liabilities (Deferred revenue) relate to payments received in advance of the satisfaction of performance under the contract. We receive payments from customers based on the terms established in our contracts. The following table summarizes our contract assets and liabilities balances (in millions):

---

| | | |
|:---|:---|:---|
| | **September 30, 2025** | **September 30, 2024** |
| Contract assets, current <sup>(1)</sup> | $280 | $270 |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<sup>(4)</sup>Included in other non-current liabilities on the consolidated balance sheets.

The increase in non-current contract assets is attributable to expected customer billing of certain contracts exceeding one year from September 30, 2025. For the fiscal year ended September 30, 2025, the revenue recognized that was included in the contract liability balance at the beginning of the fiscal year was approximately $125 million.

The requirement to repay this advance is based on year-over-year commercial aviation revenue growth for certain product lines at CMC Electronics, which is a wholly-owned subsidiary of TransDigm. As of September 30, 2025 and 2024, the outstanding balance of these advances were $12 million and $17 million, respectively.

***Obligations under Finance Leases***

The Company leases certain buildings and equipment under finance leases. The present value of the minimum finance lease payments, net of the current portion, represents a balance of $284 million and $262 million at September 30, 2025 and 2024, respectively. The increase in fiscal 2025 is primarily attributable to certain new leases of facilities and amendments to previous agreements qualifying as lease modifications resulting in a change in classification from an operating lease to a finance lease. Refer to Note 17, "Leases," for further disclosure of the Company's lease obligations.

***Senior Secured Term Loans Facility***

As of September 30, 2025, TransDigm had $11,124 million in fully drawn term loans under the Term Loans Facility, $910 million in revolving commitments, of which $857 million was available to the Company, subject to an interest rate of 2.25% per annum. As of September 30, 2024, TransDigm had $8,702 million in fully drawn term loans, $910 million in revolving commitments, of which $843 million was available to the Company, subject to an interest rate of 2.25% per annum. The unused portion of the revolving commitments is subject to a fee of 0.5% per annum for both fiscal 2025 and 2024. The total fees incurred on the unused portion of the revolving commitments were not material in fiscal 2025 or fiscal 2024. TransDigm is in compliance with all the covenants contained in the Term Loans Facility.

The interest rates per annum applicable to the loans under the Term Loans Facility are, at TransDigm's option, equal to either an alternate base rate or an adjusted Term SOFR for one, three or six-months thereafter (in each case, subject to the availability thereof), interest periods chosen by TransDigm, in each case, plus an applicable margin percentage. The adjusted Term SOFR related to the existing term loans are not subject to a floor. Refer to Note 18, "Derivatives and Hedging Activities," for information about how our interest rate swaps, cap and collar agreements are used to hedge and offset, respectively, the variable interest rates on the Term Loans Facility.

**11.&nbsp;&nbsp;&nbsp;&nbsp;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 following summarizes the carrying amounts and fair values of financial instruments (in millions):

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 or disclosed using unobservable inputs (i.e., Level 3).

The Company's derivatives consist of interest rate swap, cap and collar agreements and foreign currency exchange contracts. The fair values of the interest rate swap, cap and collar agreements were derived by taking the net present value of the expected cash flows using observable market inputs (Level 2) such as SOFR rate curves, futures, volatilities and basis spreads (when applicable). The fair values of the foreign currency exchange contracts were derived by using Level 2 inputs based on observable spot and forward exchange rates in active markets. 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 material impact to the fair value of derivative assets based on the Company's evaluation of counterparties' credit risks.

The estimated fair value of the Company's term loans was based on information provided by the agent under the Company's Credit Agreement. The estimated fair values of the Company's notes were based upon quoted market prices.

The fair value of cash and cash equivalents, trade accounts receivable-net and accounts payable approximated carrying value due to the short-term nature of these instruments at September 30, 2025 and 2024.

The components of the deferred taxes consist of the following (in millions):

---

| | | |
|:---|:---|:---|

| &nbsp;&nbsp;&nbsp;&nbsp;Total net deferred tax assets (liabilities) | $(759) | $(766) |

---

At September 30, 2025, the Company has state net operating loss carryforwards of approximately $780 million, German net operating loss carryforwards of $66 million and United Kingdom net operating loss carryforwards of approximately $93 million that expire in various fiscal years from 2026 to 2045. The Company has U.S. and non-U.S. tax credit carryforwards of $9 million that expire beginning in fiscal year 2026.

The deferred tax assets for the interest expense limitation, net operating losses, and tax credit carryforwards are reduced by a valuation allowance for the amount of such assets that the Company believes will not be realized.

With limited exception, no provision has been made for income taxes on undistributed earnings of foreign subsidiaries of approximately $30 million at September 30, 2025, since it is the Company's intention to indefinitely reinvest such undistributed earnings. The cash that is permanently reinvested is typically used to expand operations either organically or through acquisitions. It is not practicable to estimate the additional taxes that would be payable on the remittance of such earnings. We have provided for taxes in jurisdictions in which we are not considered indefinitely reinvested, however, such amounts are not significant.

The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction and various state, local and foreign jurisdictions. The Company is no longer subject to U.S. federal examinations for years before fiscal 2018. The Company is currently under examination for its federal income taxes in Canada for fiscal years 2013 through 2019, in France for fiscal years 2020 through 2022, and in Germany for fiscal years 2017 through 2019. In addition, the Company is subject to state income tax examinations for fiscal years 2015 and later.

A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows (in millions):

---

| | | |
|:---|:---|:---|
| | **2025** | **2024** |
| Balance at October 1 | $14 | $17 |
| Additions based on tax positions related to the prior year | 7 | 1 |
| Additions based on tax positions related to the current year | 2 |  |
| Reductions based on tax positions related to the prior year |  |  |
| Settlement with tax authorities |  | (3) |
| Lapse in statute of limitations |  | (1) |
| Balance at September 30 | $23 | $14 |

---

Unrecognized tax benefits at September 30, 2025 and 2024, the recognition of which would have an effect on the effective tax rate for each fiscal year, amounted to $23 million and $14 million, respectively. The Company classifies all income tax-related interest and penalties as income tax expense, which were not significant for the years ended September 30, 2025 and 2024. As of September 30, 2025 and 2024, the Company accrued $5 million and $4 million, respectively, for the potential payment of interest and penalties. Within the next twelve months, it is reasonably possible that unrecognized tax benefits could be reduced by approximately $2 million resulting from the resolution or closure of tax examinations. Any increase in the amount of unrecognized tax benefits within the next twelve months is not expected to be material.

On July 4, 2025, H.R. 1, commonly referred to as the One Big Beautiful Bill Act (the "Act") was signed into law. It contains a broad range of tax reform provisions affecting businesses. The majority of these provisions will impact us starting in fiscal year 2027. We continue to evaluate the future effects of the Act on our effective tax rate and cash tax position. The impact of the legislation on our operating results for the year ended September 30, 2025 was not material.

**13.&nbsp;&nbsp;&nbsp;&nbsp;COMMITMENTS AND CONTINGENCIES**

During the ordinary course of business, the Company is from time to time threatened with, or may become a party to, legal actions and other proceedings such as product liability claims, employee claims, workers' compensation claims and class action lawsuits. Insurance may cover some of the costs associated with these claims and proceedings. While the Company is currently involved in certain legal proceedings, it believes the results of these proceedings will not have a material adverse effect on its financial condition, results of operations, or cash flows.

***Environmental Liabilities* –** Our operations and facilities are subject to a number of federal, state, local and foreign environmental laws and regulations that govern, among other things, discharges of pollutants into the air and water, the generation, handling, storage and disposal of hazardous materials and wastes, the remediation of contamination and the health and safety of our employees. Environmental laws and regulations may require that the Company investigate and remediate the effects of the release or disposal of materials at sites associated with past and present operations. Certain facilities and third-party sites utilized by the Company have been identified as potentially responsible parties under the federal superfund laws and comparable state laws. The Company is currently involved in the investigation and remediation of a number of sites under applicable laws.

Estimates of the Company's environmental liabilities are based on current facts, laws, regulations and technology. These estimates take into consideration the Company's prior experience and professional judgment of the Company's environmental advisors. Estimates of the Company's environmental liabilities are further subject to uncertainties regarding the nature and extent of site contamination, the range of remediation alternatives available, evolving remediation standards, imprecise engineering evaluations and cost estimates, the extent of corrective actions that may be required and the number and financial condition of other potentially responsible parties, as well as the extent of their responsibility for the remediation.

Accordingly, as investigation and remediation proceed, it is likely that adjustments in the Company's accruals will be necessary to reflect new information. The amounts of any such adjustments could have a material adverse effect on the Company's results of operations or cash flows in a given period. Based on currently available information, however, the Company does not believe that future environmental costs in excess of those accrued with respect to sites for which the Company has been identified as a potentially responsible party are likely to have a material adverse effect on the Company's financial condition or results of operations.

Environmental liabilities are recorded when the liability is probable and the costs are reasonably estimable, which generally is not later than at completion of a feasibility study or when the Company has recommended a remedy or has committed to an appropriate plan of action. The Company also takes into consideration the estimated period of time in which payments will be required. The liabilities are reviewed periodically and, as investigation and remediation proceed, adjustments are made as necessary. Liabilities for losses from environmental remediation obligations do not consider the effects of inflation and anticipated expenditures are not discounted to their present value. The liabilities are not offset by possible recoveries from insurance carriers or other third parties, but do reflect anticipated allocations among potentially responsible parties at federal superfund sites or similar state-managed sites, third party indemnity obligations, and an assessment of the likelihood that such parties will fulfill their obligations at such sites.

The Company's consolidated balance sheets includes current environmental remediation obligations at both September 30, 2025 and 2024 of $5 million classified as a component of accrued and other current liabilities, respectively, and non-current environmental remediation obligations at September 30, 2025 and 2024 of $33 million and $36 million classified as a component of other non-current liabilities, respectively.

The Company's segments are reported on the same basis used internally by our Chief Operating Decision Maker ("CODM") for evaluating performance and for allocating resources. The Company's CODM is collectively the President and Chief Executive Officer and Co-Chief Operating Officers. The primary measurement used internally by our CODM and management to review and assess the operating performance of each segment is EBITDA As Defined. Actual results are compared to plan, forecast and prior year on a monthly basis. The Company defines EBITDA As Defined as earnings before interest, taxes, depreciation and amortization plus certain non-operating items recorded as corporate expenses including non-cash compensation charges incurred in connection with the Company's stock incentive or deferred compensation plans, foreign currency gains and losses, acquisition-integration costs, acquisition transaction-related expenses, and refinancing costs. Acquisition transaction and integration-related expenses represent costs incurred to integrate acquired businesses into TD Group's operations; facility relocation costs and other acquisition-related costs; transaction and valuation-related costs for acquisitions comprising deal fees, legal, financial and tax due diligence expenses; amortization expense of inventory step-up recorded in connection with the purchase accounting of acquired businesses.

EBITDA As Defined is not a measurement of financial performance under U.S. 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 U.S. GAAP.

The accounting policies for each segment are the same as those described in the summary of significant accounting policies in Note 1 to 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 immaterial for the periods presented below. Corporate consists of our corporate offices. Corporate expenses consist primarily of compensation, benefits, professional services and other administrative costs incurred by the corporate offices. Corporate assets consist primarily of cash and cash equivalents. Corporate expenses and assets reconcile reportable segment data to the consolidated totals. An immaterial amount of corporate expenses is allocated to the operating segments.

The following table sets forth, for the periods indicated, certain financial information by reportable segment, which includes a reconciliation of EBITDA As Defined to consolidated income from continuing operations before income taxes (in millions):

**16.&nbsp;&nbsp;&nbsp;&nbsp;STOCK-BASED COMPENSATION**

The Company's equity compensation plans are designed to assist the Company in attracting, retaining, motivating and rewarding key employees, directors or consultants, and promoting the creation of long-term value for stockholders by closely aligning the interests of these individuals with those of the Company's stockholders. The Company's equity compensation plans provide for the granting of stock options.

Non-cash stock compensation expense recognized by the Company during the fiscal years ended September 30, 2025, 2024 and 2023 was $152 million, $188 million and $135 million, respectively. The related tax benefit for the fiscal years ended September 30, 2025, 2024 and 2023 was $24 million, $24 million and $15 million, respectively. Of the non-cash stock compensation expense recorded in fiscal 2025, 2024 and 2023, $150 million, $134 million and $112 million was recorded as a component of additional paid in capital and less than $2 million, $54 million and $23 million was recorded as a component of other non-current liabilities. The liability awards relate to stock options granted between fiscal 2017 to fiscal 2020 from the 2014 stock option plan to certain employees in lieu of these individuals receiving salary and bonus compensation paid in cash. The vesting of the stock options are subject to the achievement of the same operating performance goals as other grants. The liability is remeasured each reporting period based on the market value of our common shares on the last day of the reported period. The other non-current liabilities related to stock-based compensation was $102 million as of September 30, 2025 and 2024.

The weighted-average grant date fair value of options granted during the fiscal years ended September 30, 2025, 2024 and 2023 was $549.03, $397.31 and $251.73, respectively. The total fair value of options vested during fiscal years ended September 30, 2025, 2024 and 2023 was $107 million, $97 million and $80 million, respectively.

Compensation expense is recognized based upon probability assessments of awards that are expected to vest in future periods, adjusted for expected forfeitures. Such probability assessments are subject to revision and, therefore, unrecognized compensation expense is subject to future changes in estimate. As of September 30, 2025, there was approximately $208 million of total unrecognized compensation expense related to non-vested awards expected to vest, which is expected to be recognized over a weighted-average period of 1.8 years.

The fair value of the Company's employee stock options was estimated at the date of grant or modification using a Black-Scholes option-pricing model with the following weighted average assumptions for all options granted during the fiscal years ended:

---

| | | | |
|:---|:---|:---|:---|
| | **Fiscal Years Ended September 30,** | **Fiscal Years Ended September 30,** | **Fiscal Years Ended September 30,** |
| | **2025** | **2024** | **2023** |
| Risk-free interest rate | 4.0% to 4.5% | 4.1% to 4.7% | 3.5% to 4.2% |
| Expected life of options | 6.5 years | 6.5 years | 6.5 years |
| Expected dividend yield of stock |  |  |  |
| Expected volatility of stock | 32.5% | 33.5% | 32.5% |

---

------

<u>[**Table of Contents**](#i348eacf94acd4c1ca064b10a69770101_7)</u>

The risk-free interest rate is based upon the U.S. Treasury bond rates with a term similar to the expected life of the award as of the grant date or modification date. The average expected life of stock-based awards is based on the Company's actual historical exercise experience. The Company uses actual historical changes in the market value of its stock to calculate the volatility assumption as it is management's belief that this is the best indicator of future volatility. The Company estimates stock option forfeitures based on historical data. The total number of stock options expected to vest is adjusted by actual and estimated forfeitures. Changes to the actual and estimated forfeitures will result in a cumulative adjustment in the period of change. Notwithstanding the special cash dividends declared and paid from time to time, the Company historically has not declared and paid regular cash dividends and does not anticipate declaring and paying regular cash dividends in future periods. Furthermore, since vested options under the Company's equity compensation plans are entitled to participate in dividend equivalents (refer to "*Dividends and Dividend Equivalent Plans*" section below) upon declaration of a special dividend, no expected dividend yield is assumed.

***2019 Stock Option Plan***

In August 2019, the Board of Directors of TD Group adopted a new stock option plan, which was subsequently approved by stockholders on October 3, 2019. The 2019 stock option plan permits TD Group to award stock options to our key employees, directors or consultants. The total number shares of TD Group common stock reserved for issuance or delivery under the 2019 stock option plan is 4,000,000, subject to adjustment in the event of any stock dividend or split, reorganization, recapitalization, merger, share exchange or any other similar corporate transaction or event.

***Performance Vested Stock Options*** – Generally all of the options granted through September 30, 2025 under the 2019 stock option plan have been pursuant to an equity incentive program adopted by the Company in 2008. Under the 2008 equity incentive program, generally all of the options granted will vest based on the Company's achievement of established operating performance goals. The following table summarizes the activity, pricing and other information for the Company's performance vested stock-based award activity during the fiscal year ended September 30, 2025:

**17.&nbsp;&nbsp;&nbsp;&nbsp;LEASES**

The Company leases certain manufacturing facilities, offices, land, equipment and vehicles. Such leases, some of which are noncancellable and, in many cases, include renewals, expire at various dates. Such options to renew are included in the lease term when it is reasonably certain that the option will be exercised. The Company's lease agreements typically do not contain any significant residual value guarantees or restrictive covenants, and payments within certain lease agreements are adjusted periodically for changes in an index or rate.

The Company determines if an arrangement is a lease at inception. Operating lease assets and liabilities are recognized at the commencement date of the lease based on the present value of lease payments over the lease term. Lease assets represent the Company's right to use an underlying asset for the lease term and lease liabilities represent the Company's obligation to make lease payments arising from the lease. The discount rate implicit within our leases is generally not determinable and therefore we determine the discount rate based on our incremental borrowing rate. The incremental borrowing rate for our leases is determined based on the lease term and the currency in which lease payments are made. The length of a lease term includes options to extend or terminate the lease when it is reasonably certain that the Company will exercise those options. The Company made an accounting policy election to not recognize lease assets or liabilities for leases with a term of twelve months or less. Additionally, when accounting for leases, the Company combines payments for leased assets, related services and other components of a lease.

The components of lease expense for the fiscal years ended September 30, 2025 and 2024 are as follows (in millions):

**18.&nbsp;&nbsp;&nbsp;&nbsp;DERIVATIVES AND HEDGING ACTIVITIES**

The Company is exposed to, among other things, the impact of changes in foreign currency exchange rates and 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. These derivative financial instruments do not subject the Company to undue risk, as gains and losses on these instruments generally offset gains and losses on the underlying assets, liabilities, or anticipated transactions that are being hedged. The Company has agreements with each of its swap, cap and collar counterparties that contain a provision whereby if the Company defaults on the Credit Agreement, the Company could also be declared in default on its swaps, cap and collars resulting in an acceleration of settlement under the swaps, cap and collars.

All derivative financial instruments are recorded at fair value in the consolidated balance sheets. For a derivative that has not been designated as an accounting hedge, the change in the fair value is recognized immediately through earnings. For a derivative that has been designated as an accounting hedge of an existing asset or liability (a fair value hedge), the change in the fair value of both the derivative and underlying asset or liability is recognized immediately through earnings. For a derivative designated as an accounting hedge of an anticipated transaction (a cash flow hedge), the change in the fair value is recorded on the consolidated balance sheets in accumulated other comprehensive loss to the extent the derivative is effective in mitigating the exposure related to the anticipated transaction. The change in the fair value related to the ineffective portion of the hedge, if any, is immediately recognized in earnings. The amount recorded within accumulated other comprehensive loss is reclassified into earnings in the same period during which the underlying hedged transaction affects earnings.

***Interest Rate Swap, Cap and Collar Agreements*** – Interest rate swap, cap and collar agreements are used to manage interest rate risk associated with floating rate borrowings, specifically the term loans, under our Credit Agreement. 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. The 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 from the effective date through the maturity date of the respective interest rate swap, cap and collar agreements, thereby reducing the impact of interest rate movements on future interest expense.

During the fourth quarter of fiscal 2025, we entered into forward starting interest rate collar agreements and interest rate swap agreements. The interest rate collar agreements, aggregating to a notional amount of $2,750 million, establish a range where we will pay the counterparties if the three-month Term SOFR rate falls below the established floor rate, and the counterparties will pay us if the three-month Term SOFR rate exceeds the ceiling rate as summarized in the table below. The collar will settle quarterly from the effective date through the maturity date. No payments or receipts will be exchanged on the interest rate collar contracts unless interest rates rise above or fall below the contracted ceiling or floor rates. The interest rate swap agreements hedge the variable interest rates on the Company's floating rate debt exposures for a fixed rate based on an aggregate notional amount of $2,750 million. The swap will settle quarterly from the effective date through the maturity date. The Company does not have any interest rate cap agreements as of September 30, 2025.

The tables below summarize the key terms of the swaps and collars as of September 30, 2025 (aggregated by effective date).

These derivative instruments qualify as effective cash flow hedges under U.S. GAAP. For our cash flow hedges, the effective portion of the gain or loss from the financial instruments is 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 affects earnings. As the interest rate swap, cap and collar 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 consolidated statements of income. Cash flows related to the derivative contracts are included in cash flows from operating activities on the consolidated statements of cash flows.

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 non-current asset or liability. The amounts shown in the table below represent the gross amounts of recognized assets and liabilities, the amounts offset in the consolidated balance sheets and the net amounts of assets and liabilities presented therein (in millions):

Based on the fair value amounts determined as of September 30, 2025, the estimated net amount of existing losses (gains) and caplet amortization expected to be reclassified into interest expense-net within the next twelve months is approximately $7 million.

***Foreign Currency Forward Exchange Contracts*** – The Company transacts business in various foreign currencies, which subjects the Company's cash flows and earnings to exposure related to changes in foreign currency exchange rates. These exposures arise primarily from purchases or sales of products and services from third parties. Foreign currency forward exchange contracts provide for the purchase or sale of foreign currencies at specified future dates at specified exchange rates, and are used to offset changes in the fair value of certain assets or liabilities or forecasted cash flows resulting from transactions denominated in foreign currencies. At September 30, 2025, the Company has outstanding foreign currency forward exchange contracts to sell U.S. dollars with notional amounts of $118 million. The maximum duration of the Company's foreign currency cash flow hedge contracts at September 30, 2025 is twelve months. These notional values consist of contracts for the Canadian dollar and the euro and are stated in U.S. dollar equivalents at spot exchange rates at the respective trade dates. Amounts related to foreign currency forward exchange contracts included in accumulated other comprehensive loss in stockholders' deficit are reclassified into net sales when the hedged transaction settles. As of September 30, 2025, the Company expects to record a net loss of approximately $2 million on foreign currency forward exchange contracts designated as cash flow hedges to net sales over the next twelve months.

In the event the Executive's employment with the Company is terminated for any reason, the Company shall pay the Executive (or the Executive's beneficiary in the event of the Executive's death) any unpaid Annual Base Salary that has accrued as of the Date of Termination, any unreimbursed expenses due to the Executive in accordance with the Company's expense reimbursement policy and an amount equal to compensation for accrued but unused sick days and vacation days. The Company shall permit the Executive to elect to continue health plan coverage in accordance with the requirements of applicable law (e.g., COBRA coverage), at the applicable monthly cost charged for such coverage (the "Monthly COBRA Coverage Continuation Rate"). The Company may require the Executive to complete and file any election forms that are generally required of other employees to obtain COBRA coverage; and the Executive's COBRA coverage may be terminable in accordance with applicable law. The Executive shall also be entitled to accrued, vested benefits under the Company's benefit plans and programs as provided therein. The Executive shall be entitled to the additional payments and benefits described below only as set forth herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) <u>Termination without Cause, Resignation for Good Reason or Termination by Reason of Death or Disability</u>. Subject to Sections 6(c) and (d) and the restrictions contained herein, in the event of the Executive's termination without Cause (pursuant to Section 5(a)(v)), resignation for Good Reason (pursuant to Section 5(a)(iv)) or Disability (pursuant to Section 5(a)(i) or (ii), respectively), the Company shall pay to the Executive the amounts described in subsection (a).

For purposes of this Agreement the Severance Amount is equal to the sum of:

Patrick Murphy&nbsp;&nbsp;&nbsp;&nbsp;

**&nbsp;&nbsp;&nbsp;&nbsp;Page 5 of 12**

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) 1.25 times the Executive's Annual Base Salary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) 1.25 times the greater of (A) the total of all bonuses paid (or payable) to the Executive in respect of the fiscal year ending immediately prior to the Date of Termination, excluding any bonuses that are extraordinary in nature (e.g., a transaction related bonus) or (B) the target bonuses for the fiscal year in which the Date of Termination falls, determined in accordance with the Company's bonus program or programs, if any; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) 18.0 times the difference of (A) the Monthly COBRA Continuation Coverage Rate determined as of the Date of Termination for the Executive's applicable health plan coverage as in effect on such date, less (B) the monthly cost to Executive that is being charged for such coverage as of the Date of Termination.

The Severance Amount as so determined shall be payable to the Executive (or the Executive's beneficiary) in substantially equal installments over the 12-month period following the Date of Termination (the "Payment Period") commencing no later than thirty (30) days following the execution and non-revocation of the Release, in accordance with the Company's regular payroll practices. The first installment payment shall include all amounts that would have otherwise been paid to the Executive during the period beginning on the Date of Termination and ending on the first installment payment date. Notwithstanding the foregoing, in the event that the end of the thirty (30) day notice and revocation period for the Release would result in the first installment payment occurring in the taxable year following the year in which the Date of Termination occurs, the first installment payment shall be made in the taxable year following the year in which the Date of Termination occurs. Each payment under this Section 6(b) shall be considered a separate payment and not one of a series of payments for purposes of Code Section 409A.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (c) <u>Benefits Provided Upon Termination of Employment</u>. If the Executive's termination or resignation does not constitute a "separation from service," as such term is defined under Code Section 409A, the Executive shall nevertheless be entitled to receive all of the payments and benefits that the Executive is entitled to receive under this Agreement on account of the Executive's termination of employment. However, the payments and benefits that the Executive is entitled to under this Agreement shall not be provided to the Executive until such time as the Executive has incurred a "separation from service" within the meaning of Code Section 409A.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) <u>Payments on Account of Termination to a Specified Employee</u>. Notwithstanding the foregoing provisions of Sections 6(a), 6(b) or 6(c), in the event that the Executive is determined to be a Specified Employee at the time of the Executive's termination of employment under this Agreement (or, if later, the Executive's "separation from service" under Code Section 409A), to the extent that a payment, reimbursement or benefit under Section 6(b) is considered to provide for a "deferral of compensation" (as determined under Code Section 409A), then such payment, reimbursement or benefit shall not be paid or provided until six months after the Executive's separation from service, or the Executive's death, whichever occurs first. Any payments, reimbursements or benefits that are withheld

Amended & Restated Employment Agreement

Patrick Murphy&nbsp;&nbsp;&nbsp;&nbsp;

**&nbsp;&nbsp;&nbsp;&nbsp;Page 6 of 12**

------

under this provision for the first six months shall be payable in a lump sum on the first day after the six-month anniversary of such termination of employment (or, if later, the Executive's "separation from service" under Code Section 409A). The restrictions in this Section 6(d) shall be interpreted and applied solely to the minimum extent necessary to comply with the requirements of Code Section 409A(a)(2)(B). Accordingly, payments, benefits or reimbursements under Section 6(b) or any other part of this Agreement may nevertheless be provided to Executive within the six-month period following the date of Executive's termination of employment under this Agreement (or, if later, the Executive's "separation from service" under Code Section 409A), to the extent that it would nevertheless be permissible to do so under Code Section 409A because those payments, reimbursements or benefits are (i) described in Treasury Regulations Section 1.409A-1(b)(9)(iii) (i.e., payments within the limitations therein that are being made on account of an involuntary termination or termination for good reason, within the meaning of the Treasury Regulations), or (ii) described in Treasury Regulation Section 1.409A-1(b)(4) (i.e., payments which are treated as short-term deferrals within the meaning of the Treasury Regulations), or (iii) benefits described in Treasury Regulations Section 1.409A-1(b)(9)(v) (e.g. health care benefits).

7. <u>Competition; Nonsolicitation</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) During the Term and, following any termination of the Executive's employment, for a period equal to (i) the Payment Period, in the case of a termination of employment for which payments are made pursuant to Section 6(b) hereof, or (ii) 24 months from the date of such termination in the event of a voluntary termination of employment by the Executive without Good Reason, or a termination by the Company for Cause, the Executive shall not, without the prior written consent of the Board, directly or indirectly engage in, or have any interest in, or manage or operate any person, firm, corporation, partnership or business (whether as director, officer, employee, agent, representative, partner, security holder, consultant or otherwise) that engages in any business (other than a business that constitutes less than 5% of the relevant entity's net revenue and a proportionate share of its operating income) which competes with any business of the Company or any entity owned by it anywhere in the world; provided, however, that the Executive shall be permitted to acquire a stock interest in such a corporation provided such stock is publicly traded and the stock so acquired does not represent more than one percent of the outstanding shares of such corporation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) During the Term and for a period of two years following any termination of the Executive's employment, the Executive shall not, directly or indirectly, on the Executive's own behalf or on behalf of any other person or entity, whether as an owner, employee, service provider or otherwise, solicit or induce any person who is or was employed by, or providing consulting services to, the Company or any of its subsidiaries during the twelve-month period prior to the date of such termination, to terminate their employment or consulting relationship with the Company or any such subsidiary.

Patrick Murphy&nbsp;&nbsp;&nbsp;&nbsp;

**&nbsp;&nbsp;&nbsp;&nbsp;Page 7 of 12**

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) In the event the agreement in this Section 7 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it shall be interpreted to extend only over the maximum period of time for which it may be enforceable, and/or over the maximum geographical area as to which it may be enforceable and/or to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action.

8. <u>Nondisclosure of Proprietary Information</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Except as required in the faithful performance of the Executive's duties hereunder or pursuant to subsection (c), the Executive shall, in perpetuity, maintain in confidence and shall not directly, indirectly or otherwise, use, disseminate, disclose or publish, or use for the Executive's benefit or the benefit of any person, firm, corporation or other entity any confidential or proprietary information or trade secrets of or relating to the Company, including, without limitation, information with respect to the Company's operations, processes, products, inventions, business practices, finances, principals, vendors, suppliers, customers, potential customers, marketing methods, costs, prices, contractual relationships, regulatory status, compensation paid to employees or other terms of employment, except for such information which is or becomes publicly available other than as a result of a breach by the Executive of this Section 8, or deliver to any person, firm, corporation or other entity any document, record, notebook, computer program or similar repository of or containing any such confidential or proprietary information or trade secrets. The parties hereby stipulate and agree that as between them the foregoing matters are important, material and confidential proprietary information and trade secrets and affect the successful conduct of the businesses of the Company (and any successor or assignee of the Company).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Upon termination of the Executive's employment with the Company for any reason, the Executive shall promptly deliver to the Company all correspondence, drawings, manuals, letters, notes, notebooks, reports, programs, plans, proposals, financial documents, or any other documents concerning the Company's customers, business plans, marketing strategies, products or processes and/or which contain proprietary information or trade secrets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Executive may respond to a lawful and valid subpoena or other legal process but shall give the Company the earliest possible notice thereof, shall, as much in advance of the return date as possible, make available to the Company and its counsel the documents and other information sought and shall assist such counsel in resisting or otherwise responding to such process. Notwithstanding anything in this Agreement or otherwise to the contrary, nothing in this Agreement or otherwise prevents the Executive from providing, without prior notice to the Company, information to governmental authorities regarding possible legal violations or otherwise testifying or participating in any investigation or proceeding by any governmental authorities regarding possible legal violations, and for purpose of clarity the Executive is not prohibited from providing information voluntarily to the Securities and Exchange Commission pursuant to Section 21F of the Securities Exchange Act of 1934, as amended.

9. <u>Injunctive Relief</u>. It is recognized and acknowledged by the Executive that a breach of the covenants contained in Sections 7 and 8 will cause irreparable damage to the Company and its goodwill, the exact amount of which will be difficult or impossible to ascertain, and that the remedies at law for any such breach will be inadequate. Accordingly, the Executive agrees that in the event of a breach of any of the covenants contained in Sections 7 and 8, in addition to any other remedy which may be available at law or in equity, the Company shall be entitled to specific performance and injunctive relief.

10. <u>Survival</u>. The expiration or termination of the Term shall not impair the rights or obligations of any party hereto which shall have accrued hereunder prior to such expiration.

------

the Executive's employment under Section 5(a)(iv), and specifying a Date of Termination which, in the case of the Executive's resignation for Good Reason or the Executive's resignation without Good Reason pursuant to Section 5(a)(iv) or 5(a)(vi), respectively, shall be at least 90 days following the date of such notice (a "Notice of Termination"). In the event of the Executive's resignation for Good Reason pursuant to Section 5(a)(iv), the Company shall have the right, if the basis for such Good Reason is curable, to cure the same within 30 days following the receipt of the Notice of Termination, and Good Reason shall not be deemed to exist if the Company cures the event giving rise to Good Reason within such 30-day period. The Executive shall continue to receive the Executive's Annual Base Salary, annual bonus and all other compensation and perquisites referenced in Section 4 through the Date of Termination.

6. <u>Severance Payments</u>.

(a) <u>Termination for any Reason</u>. In the event the Executive's employment with the Company is terminated for any reason, the Company shall pay the Executive (or the Executive's beneficiary in the event of the Executive's death) any unpaid Annual Base Salary that has accrued as of the Date of Termination, any unreimbursed expenses due to the Executive in accordance with the Company's expense reimbursement policy and an amount equal to compensation for accrued but unused sick days and vacation days. The Company shall permit the Executive to elect to continue health plan coverage in accordance with the requirements of applicable law (e.g. COBRA coverage), at the applicable monthly cost charged for such coverage (the "Monthly COBRA Coverage Continuation Rate"). The Company may require the Executive to complete and file any election forms that are generally required of other employees to obtain COBRA coverage; and the Executive's COBRA coverage may be terminable in accordance with applicable law. The Executive shall also be entitled to accrued, vested benefits under the Company's benefit plans and programs as provided therein. The Executive shall be entitled to the additional payments and benefits described below only as set forth herein.

(b) <u>Termination without Cause, Resignation for Good Reason or Termination by Reason of Death or Disability</u>. Subject to Sections 6(c) and (d) and the restrictions contained herein, in the event of the Executive's Termination without Cause (pursuant to Section 5(a)(v)), Resignation for Good Reason (pursuant to Section 5(a)(iv)) or termination by reason of death or Disability (pursuant to Section 5(a)(i) or (ii), respectively), the Company shall pay to the Executive the amounts described in subsection (a). In addition, subject to Sections 6(c) and (d) and the restrictions contained herein, and in the case of Termination without Cause (pursuant to Section 5(a)(v), Resignation for Good Reason (pursuant to Section 5(a)(iv)) or Disability (pursuant to Section 5(a)(ii)) subject to the Executive's execution and non-revocation of a customary release in favor of the Company (the "Release") no later than thirty (30) days following the Date of Termination, the Company shall pay to the Executive (or the Executive's beneficiary in the event of the Executive's death) an amount equal to the

Employment Agreement Armani Vadiee

**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Page 5 of 12**

------

"Severance Amount" described below. For purposes of this Agreement the Severance Amount is equal to the sum of:

(i) 1.25 times the Executive's Annual Base Salary,

(ii) 1.25 times the greater of (A) the total of all bonuses paid (or payable) to Executive in respect of the fiscal year ending immediately prior to the Date of Termination, excluding any bonuses that are extraordinary in nature (e.g., a transaction related bonus) or (B) the target bonuses for the fiscal year in which the Date of Termination falls, determined in accordance with the Company's bonus program or programs, if any, and

(iii) 18.0 times the difference of (A) the Monthly COBRA Continuation Coverage Rate determined as of the Date of Termination for the Executive's applicable health plan coverage as in effect on such date, less (B) the monthly cost to Executive that is being charged for such coverage as of the Date of Termination.

The Severance Amount as so determined shall be payable to the Executive (or the Executive's beneficiary) in substantially equal installments over the 12-month period following the Date of Termination (the "Payment Period") commencing no later than thirty (30) days following the execution and non-revocation of the Release, in accordance with the Company's regular payroll practices. The first installment payment shall include all amounts that would have otherwise been paid to the Executive during the period beginning on the Date of Termination and ending on the first installment payment date. Notwithstanding the foregoing, in the event that the end of the thirty (30) day notice and revocation period for the Release would result in the first installment payment occurring in the taxable year following the year in which the Date of Termination occurs, the first installment payment shall be made in the taxable year following the year in which the Date of Termination occurs. Each payment under this Section 6(b) shall be considered a separate payment and not one of a series of payments for purposes of Code Section 409A.

(c) <u>Benefits Provided Upon Termination of Employment</u>. If the Executive's termination or resignation does not constitute a "separation from service," as such term is defined under Code Section 409A, the Executive shall nevertheless be entitled to receive all of the payments and benefits that the Executive is entitled to receive under this Agreement on account of the Executive's termination of employment. However, the payments and benefits that the Executive is entitled to under this Agreement shall not be provided to the Executive until such time as the Executive has incurred a "separation from services" within the meaning of Code Section 409A.

(d) <u>Payments on Account of Termination to a Specified Employee</u>. Notwithstanding the foregoing provisions of Sections 6(a), 6(b) or 6(c), in the event that the Executive is determined to be a Specified Employee at the time of the Executive's termination of employment under this Agreement (or, if later, the Executive's "separation from service" under Code Section 409A), to the extent that a payment, reimbursement or benefit under

Employment Agreement Armani Vadiee

**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Page 6 of 12**

------

Section 6(b) is considered to provide for a "deferral of compensation" (as determined under Code Section 409A), then such payment, reimbursement or benefit shall not be paid or provided until six months after the Executive's separation from service, or the Executive's death, whichever occurs first. Any payments, reimbursements or benefits that are withheld under this provision for the first six months shall be payable in a lump sum on the first day after the six-month anniversary of such termination of employment (or, if later, the Executive's "separation from service" under Code Section 409A). The restrictions in this Section 6(d) shall be interpreted and applied solely to the minimum extent necessary to comply with the requirements of Code Section 409A(a)(2)(B). Accordingly, payments, benefits or reimbursements under Section 6(b) or any other part of this Agreement may nevertheless be provided to Executive within the six-month period following the date of Executive's termination of employment under this Agreement (or, if later, the Executive's "separation from service" under Code Section 409A), to the extent that it would nevertheless be permissible to do so under Code Section 409A because those payments, reimbursements or benefits are (i) described in Treasury Regulations Section 1.409A-1(b)(9)(iii) (i.e., payments within the limitations therein that are being made on account of an involuntary termination or termination for good reason, within the meaning of the Treasury Regulations), or (ii) described in Treasury Regulation Section 1.409A-1(b)(4) (i.e., payments which are treated as short-term deferrals within the meaning of the Treasury Regulations), or (iii) benefits described in Treasury Regulations Section 1.409A-1(b)(9)(v) (e.g. health care benefits).

7. <u>Competition; Nonsolicitation</u>.

(a) During the Term and, following any termination of Executive's employment, for a period equal to (i) the Payment Period, in the case of a termination of employment for which payments are made pursuant to Section 6(b) hereof, or (ii) 24 months from the date of such termination in the event of a voluntary termination of employment by the Executive without Good Reason, or a termination by the Company for Cause, the Executive shall not, without the prior written consent of the Board, directly or indirectly engage in, or have any interest in, or manage or operate any person, firm, corporation, partnership or business (whether as director, officer, employee, agent, representative, partner, security holder, consultant or otherwise) that engages in any business (other than a business that constitutes less than 5% of the relevant entity's net revenue and a proportionate share of its operating income) which competes with any business of the Company or any entity owned by it anywhere in the world; provided, however, that the Executive shall be permitted to acquire a stock interest in such a corporation provided such stock is publicly traded and the stock so acquired does not represent more than one percent of the outstanding shares of such corporation.

(b) During the Term and for a period of two years following any termination of the Executive's employment, the Executive shall not, directly or indirectly, on the Executive's own behalf or on behalf of any other person or entity, whether as an owner, employee, service provider or otherwise, solicit or induce any person who is or was employed by, or

**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Page 7 of 12**

------

providing consulting services to, the Company or any of its subsidiaries during the twelve-month period prior to the date of such termination, to terminate their employment or consulting relationship with the Company or any such subsidiary.

(c) In the event the agreement in this Section 7 shall be determined by any court of competent jurisdiction to be unenforceable by reason of its extending for too great a period of time or over too great a geographical area or by reason of its being too extensive in any other respect, it shall be interpreted to extend only over the maximum period of time for which it may be enforceable, and/or over the maximum geographical area as to which it may be enforceable and/or to the maximum extent in all other respects as to which it may be enforceable, all as determined by such court in such action.

8. <u>Nondisclosure of Proprietary Information</u>.

(a) Except as required in the faithful performance of the Executive's duties hereunder or pursuant to subsection (c), the Executive shall, in perpetuity, maintain in confidence and shall not directly, indirectly or otherwise, use, disseminate, disclose or publish, or use for the Executive's benefit or the benefit of any person, firm, corporation or other entity any confidential or proprietary information or trade secrets of or relating to the Company, including, without limitation, information with respect to the Company's operations, processes, products, inventions, business practices, finances, principals, vendors, suppliers, customers, potential customers, marketing methods, costs, prices, contractual relationships, regulatory status, compensation paid to employees or other terms of employment, except for such information which is or becomes publicly available other than as a result of a breach by the Executive of this Section 8, or deliver to any person, firm, corporation or other entity any document, record, notebook, computer program or similar repository of or containing any such confidential or proprietary information or trade secrets. The parties hereby stipulate and agree that as between them the foregoing matters are important, material and confidential proprietary information and trade secrets and affect the successful conduct of the businesses of the Company (and any successor or assignee of the Company).

(b) Upon termination of the Executive's employment with the Company for any reason, the Executive shall promptly deliver to the Company all correspondence, drawings, manuals, letters, notes, notebooks, reports, programs, plans, proposals, financial documents, or any other documents concerning the Company's customers, business plans, marketing strategies, products or processes and/or which contain proprietary information or trade secrets.

(c) The Executive may respond to a lawful and valid subpoena or other legal process but shall give the Company the earliest possible notice thereof, shall, as much in advance of the return date as possible, make available to the Company and its counsel the documents and other information sought and shall assist such counsel in resisting or otherwise responding to such process. Notwithstanding anything in this Agreement or otherwise to the contrary, nothing in this Agreement or otherwise prevents the Executive from providing, without prior notice to the Company, information to governmental authorities regarding possible legal

Employment Agreement Armani Vadiee

**&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Page 8 of 12**

------

violations or otherwise testifying or participating in any investigation or proceeding by any governmental authorities regarding possible legal violations, and for purpose of clarity the Executive is not prohibited from providing information voluntarily to the Securities and Exchange Commission pursuant to Section 21F of the Securities Exchange Act of 1934, as amended.

9. <u>Injunctive Relief</u>. It is recognized and acknowledged by the Executive that a breach of the covenants contained in Sections 7 and 8 will cause irreparable damage to the Company and its goodwill, the exact amount of which will be difficult or impossible to ascertain, and that the remedies at law for any such breach will be inadequate. Accordingly, the Executive agrees that in the event of a breach of any of the covenants contained in Sections 7 and 8, in addition to any other remedy which may be available at law or in equity, the Company shall be entitled to specific performance and injunctive relief.

10. <u>Survival</u>. The expiration or termination of the Term shall not impair the rights or obligations of any party hereto which shall have accrued hereunder prior to such expiration.

11. <u>Binding on Successors</u>. This Agreement shall be binding upon and inure to the benefit of the Company, the Executive and their respective successors, assigns, personnel and legal representatives, executors, administrators, heirs, distributees, devisees, and legatees, as applicable.

12. <u>Governing Law</u>. This Agreement shall be governed, construed, interpreted and enforced in accordance with the substantive laws of the State of Ohio.

13. <u>Validity</u>. The invalidity or unenforceability of any provision or provisions of this Agreement shall not affect the validity or enforceability of any other provision of this Agreement, which shall remain in full force and effect.

14. <u>Notices</u>. Any notice, request, claim, demand, document or other communication hereunder to any party shall be effective upon receipt (or refusal of receipt) and shall be in writing and delivered personally or sent by telex, telecopy, or certified or registered mail, postage prepaid, as follows:

15. <u>Counterparts</u>. This Agreement may be executed in two counterparts, each of which shall be deemed to be an original, but both of which together shall constitute one and the same Agreement.

16. <u>Entire Agreement; Prior Employment Agreements</u>. The terms of this Agreement, together with the Equity Compensation Agreements are intended by the parties to be the final expression of their agreement with respect to the employment of the Executive by the Company as of and after the Effective Date, and such Agreement may not be contradicted by evidence of any prior or contemporaneous agreement. The parties further intend that this Agreement, and the aforementioned contemporaneous documents, shall constitute the complete and exclusive statement of its terms and that no extrinsic evidence whatsoever may be introduced in any judicial, administrative, or other legal proceeding to vary the terms of this Agreement.

17. <u>Amendments; Waivers</u>. This Agreement may not be modified, amended, or terminated except by an instrument in writing, signed by the Executive and the Chief Executive Officer. By an instrument in writing similarly executed, the Executive or the Company may waive compliance by the other party or parties with any provision of this Agreement that such other party was or is obligated to comply with or perform; provided, however, that such waiver shall not operate as a waiver of, or estoppel with respect to, any other or subsequent failure.

Judgment may be entered on the arbitrator's award in any court having jurisdiction; <u>provided</u>, <u>however</u>, that the Company shall be entitled to seek a restraining order or injunction in any court of competent jurisdiction to prevent any continuation of any violation of the provisions of Section 7 or 8 of this Agreement and the Executive hereby consents that such restraining order or injunction may be granted without the necessity of the Company's posting any bond; and <u>provided further</u>, that the Executive shall be entitled to seek specific performance of the Executive's right to be paid until the Date of Termination during the pendency of any dispute or controversy arising under or in connection with this Agreement.

During the Term and so long as the Executive has not breached any of the Executive's obligations set forth in Sections 7 and 8, the Company shall indemnify the Executive to the fullest extent permitted by the laws of the State of Delaware, as in effect at the time of the subject act or omission, and shall advance to the Executive reasonable attorneys' fees and expenses as such fees and expenses are incurred (subject to an undertaking from the Executive to repay such advances if it shall be finally determined by a judicial decision which is not subject to further appeal that the Executive was not entitled to the reimbursement of such fees and expenses) and he shall be entitled to the protection of any insurance policies the Company shall elect to maintain generally for the benefit of its directors and officers ("Directors and Officers Insurance") against all costs, charges and expenses incurred or sustained by the Executive in connection with any action, suit or proceeding to which the Executive may be made a party by reason of the Executive being or having been a director, officer or employee of the Company or any of its subsidiaries or the Executive serving or having served any other enterprise as a director, officer or employee at the request of the Company (other than any dispute, claim or controversy arising under or relating to this Agreement).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.4&nbsp;&nbsp;&nbsp;&nbsp;<u>Tax Obligations</u>. The Participant acknowledges that, to the extent that the aggregate Fair Market Value (determined as of the time the Option is granted) of all shares of Stock with respect to which Incentive Stock Options, including the Option, are exercisable for the first time by the Participant in any calendar year exceeds $100,000, the Option and such other options shall be Non-Qualified Stock Options to the extent necessary to comply with the limitations imposed by Section 422(d) of the Code. The Participant further acknowledges that the rule set forth in the preceding sentence shall be applied by taking the Option and other "incentive stock options" into account in the order in which they were granted, as determined under Section 422(d) of the Code and the Treasury Regulations thereunder. The Participant acknowledges that an Incentive Stock Option exercised more than three months after the Participant's Termination of Employment, other than by reason of death or Disability, will be taxed as a Non-Qualified Stock Option.

Regardless of any action the Company or Participant's employer, whether it be the Company or a Subsidiary (the "***Employer***") takes with respect to any or all income tax, social insurance, payroll tax, fringe benefits, payment on account or other tax related items related to Participant's participation in the Plan and legally applicable to Participant ("***Tax-Related Items***"), the Participant acknowledges that the ultimate liability for all Tax-Related Items is and remains the Participant's responsibility and may exceed the amount actually withheld by the Company or the Employer. The Participant further acknowledges that the Company and/or the Employer (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Option, including, but not limited to, the grant, vesting or exercise of the Option, the subsequent sale of shares of Stock acquired pursuant to such exercise and the receipt of any dividends; and (b) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Option to reduce or eliminate the Participant's liability for Tax-Related Items or achieve any particular tax result. Further, if Participant has become subject to tax in more than one jurisdiction between the Grant Date and the date of any relevant taxable or tax withholding event, as applicable, the Participant acknowledges that the Company and/or the Employer (or former Employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to the relevant taxable or tax withholding event, as applicable, the Participant will pay or make adequate arrangements satisfactory to the Company and/or the Employer to satisfy all Tax-Related Items. In this regard, Participant authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following: (i) withholding from the Participant's wages or other cash compensation paid to the Participant by the Company and/or the Employer; or (ii) withholding from proceeds of the sale of shares of Stock acquired at exercise of the Option either through a voluntary sale or through a mandatory sale arranged by the Company (on the Participant's behalf pursuant to this authorization); or (iii) withholding in shares of Stock to be issued at exercise of the Option.

Depending on the withholding method, the Company and/or the Employer may withhold or account for Tax-Related Items by considering statutory withholding rates or other withholding rates, including maximum applicable rates in the Participant's jurisdiction. If the Tax-Related Items are satisfied by withholding in shares of Stock, for tax purposes, the Participant will be deemed to have been issued the full number of shares of Stock subject to the exercised Option, notwithstanding that a number of shares of Stock are held back solely for the purpose of satisfying the Tax-Related Items.

------

Finally, the Participant shall pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold or account for as a result of Participant's participation in the Plan that cannot be satisfied by the means previously described. The Company may refuse to issue or deliver the shares of Stock or the proceeds of the sale of shares of Stock, if the Participant fails to comply with his or her obligations in connection with the Tax-Related Items.

Local insider trading laws and regulations may prohibit the cancellation or amendment of orders the Participant placed before possessing inside information. Furthermore, the Participant may be prohibited from (a) disclosing inside information to any third party, including fellow employees or service providers (other than on a "need to know" basis) and (b) "tipping" third parties or causing them to otherwise buy or sell securities. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy.

Nothing in the Grant Notice, this Agreement or the Plan gives the Participant a right to receive damages for any portion of the Option that Participant might lose due to Company, Subsidiary or Committee decisions.

The Plan, the Grant Notice and this Agreement (including all Exhibits thereto) constitute the entire agreement of the parties and supersede in their entirety all prior undertakings and agreements of the Company and Participant with respect to the subject matter hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.20&nbsp;&nbsp;&nbsp;&nbsp; <u>Waiver</u>. The Participant acknowledges that a waiver by the Company of any provision, or breach thereof, of this Agreement on any occasion shall not operate or be construed as a waiver of such provision on any other occasion or as a waiver of any other provision of this Agreement, or of any subsequent breach by the Participant or any other participant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.21&nbsp;&nbsp;&nbsp;&nbsp; <u>Section 409A</u>.

**APPENDIX**

**COUNTRY-SPECIFIC PROVISIONS TO THE**

**STOCK OPTION AGREEMENT**

***Terms and Conditions***

This Appendix includes additional terms and conditions that govern the Option granted to the Participant under the Plan if the Participant resides or works in one of the countries listed below. If the Participant is a citizen or resident (or is considered as such for local law purposes) of a country other than the country in which the Participant is currently residing and/or working, or if the Participant relocates to another country after the grant of the Option, the Company shall, in its discretion, determine to what extent the country-specific terms contained herein shall be applicable to the Participant. Certain capitalized terms used but not defined in this Appendix have the meanings set forth in the Plan and/or the Agreement.

***Notifications***

This Appendix also includes information regarding exchange controls and certain other issues of which the Participant should be aware with respect to the Participant's participation in the Plan. The information is based on the securities, exchange control and other laws as of October 2019; however, such laws are often complex and change frequently. As a result, the Company strongly recommends that the Participant does not rely on the information in this Appendix as the only source of information relating to the consequences of the Participant's participation in the Plan because the information may be out of date at the time that Participant exercises the Option or sell shares of Stock acquired under the Plan.

In addition, the information contained herein is general in nature and may not apply to the Participant's particular situation and the Company is not in a position to assure the Participant of any particular result. Accordingly, the Participant is advised to seek appropriate professional advice as to how the relevant laws in the Participant's country may apply to the Participant's situation.

Finally, the Participant understands that if he or she is a citizen or resident of a country other than the one in which Participant is currently working, transfers employment after the grant date, or is considered a resident of another country for local law purposes, the information contained herein may not apply to the Participant, and the Company shall, in its discretion, determine to what extent the terms and conditions contained herein shall apply.

The Participant's country or jurisdiction may have different data privacy laws and protections than the United States. For example, the European Commission has issued only a limited adequacy finding with respect to the United States that applies only if and to the extent companies self-certify and remain self-certified under the EU-U.S. Privacy Shield program, which is open to companies subject to the jurisdiction of the Federal Trade Commission. The Company has currently not registered for the EU-U.S. Privacy Shield program. The Company's legal basis for the transfer of data, where required, is the Participant's consent.***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e)&nbsp;&nbsp;&nbsp;&nbsp;***<u>Data Retention</u>. The Company will hold and use Data only as long as is necessary to implement, administer and manage the Participant's participation in the Plan, or as required to comply with legal or regulatory obligations including under tax, exchange control, labor and securities laws. This may mean Data is retained until after the Participant's employment or service relationship ends. When the Company or the Employer no longer need Data for any of the above purposes, they will cease processing it in this context and remove it from all of their systems used for such purposes, to the fullest extent possible.***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f)&nbsp;&nbsp;&nbsp;&nbsp;***<u>Voluntariness and Consequences of Consent Denial or Withdrawal</u>. Participation in the Plan is voluntary and the Participant is providing the consents herein on a purely voluntary basis. The Participant understands that he or she may request to stop the transfer and processing of the Data for purposes of his or her participation in the Plan and that the Participant's compensation from or service relationship with the Employer will not be affected. The only consequence of refusing or withdrawing consent is that the Company would not be able to allow the Participant to participate in the Plan.

<u>Manner of Exercise</u>**.** The following provision supplements Section 4.3 the Agreement:

Notwithstanding anything in the Plan, the Participant agrees to pay the exercise price and any Tax-Related Items solely by means of (i) cash, (ii) check or other instrument acceptable to the Company or (ii) a broker-assisted cashless exercise, whereby the broker sells some or all of the shares of Common Stock to be issued upon exercise to pay the exercise price, brokerage fees and any applicable Tax-Related Items. To the extent that tax regulatory requirements change, the Company reserves the right to permit the Participant to exercise the Option and pay the exercise price and any applicable Tax-Related Items in shares of Stock to the extent permitted by the Plan.

<u>Termination of Services</u>. Notwithstanding any provision in the Agreement to the contrary, for purposes of the Option, and except as expressly required by applicable legislation, the Participant's Termination of Services (regardless of the reason for such termination and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where the Participant is employed or providing services, or the terms of the Participant's employment or service agreement, if any) will be deemed to occur as of the date that is the earlier of: (1) the date that the Participant is no longer actively employed by the Company or any Subsidiary, or at the discretion of the Committee, or (2) the date the Participant receives notice of Termination of Services, regardless of any notice period or period of pay in lieu of such notice required under local law (including, but not limited to statutory law, regulatory law and/or common law); the Company shall have the exclusive discretion to determine when Participant is no longer employed for purposes of the Option grant (including when Participant is no longer considered as providing active service while on a leave of absence).

The following provisions will apply if the Participant is a resident of Quebec:

<u>French Language Provision</u>**.** 

The parties acknowledge that it is their express wish that the Agreement, as well as all documents, notices and legal proceedings entered into, given or instituted pursuant hereto or relating directly or indirectly hereto, be drawn up in English.

*Les parties reconnaissent avoir exigé la rédaction en anglais de la convention, ainsi que de tous documents exécutés, avis donnés et procedures judiciaries intentées, directement ou indirectement, relativement à la présente convention.*

The Participant hereby authorizes the Company and the Company's representatives to discuss with and obtain all relevant information from all personnel, professional or not, involved in the administration and operation of the Plan. The Participant further authorizes the Company, any Subsidiaries and the Committee to disclose and discuss the Plan with their advisors. The Participant further authorizes the Company or its Subsidiaries to record such information and to keep such information in the Participant's employee file.

<u>Securities Law Notice</u>. The Participant is permitted to sell shares of Stock acquired through the Plan through the designated broker appointed under the Plan, if any, provided the resale of shares of Stock acquired under the Plan takes place outside of Canada through the facilities of a stock exchange on which the shares of Stock are listed. The Company's shares of Stock are currently listed on the New York Stock Exchange.

------

<u>Foreign Asset/Account Reporting Information</u>**.** The Participant is required to report any foreign specified property on Form T1135 (Foreign Income Verification Statement) if the total value of the foreign specified property exceeds C$100,000 at any time during the year. Foreign specified property includes shares of Stock acquired under the Plan, and may include the Option. The Option must be reported (generally at a nil cost) if the C$100,000 cost threshold is exceeded because of other foreign property the Participant holds. If shares of Stock are acquired, their cost generally is the adjusted cost base ("ACB") of the shares of Stock. The ACB ordinarily would equal the fair market value of the shares of Stock at the time of acquisition, but if the Participant owns other shares of Stock, this ACB may have to be averaged with the ACB of the other shares of Stock. The Form must be filed by April 30 of the following year. The Participant should consult with a personal advisor to ensure that the Participant complies with the applicable requirements.

**FRANCE**

***Terms and Conditions***

<u>Option Type</u>. The Option is not intended to qualify for specific tax or social security treatment in France.

<u>Taxes and Other Deductions</u>**.** The following supplements Section 3.4 of the Agreement:

If payment or withholding of the income tax due is not made within ninety (90) days of the end of the tax year in which the event giving rise to the liability occurred or such other period specified in Section 222(1)(c) of the U.K. Income Tax (Earnings and Pensions) Act 2003 (the "Due Date"), the amount of any uncollected tax liability shall

------

constitute a loan owed by the Participant to the Company or the Employer, as applicable, effective as of the Due Date. The Participant agrees that the loan will bear interest at the then-current official rate of Her Majesty's Revenue & Customs ("HMRC"), it will be immediately due and repayable, and the Company or the Employer, as applicable, may recover it at any time thereafter by any of the means referred to in Section 3.4 of the Agreement.

Notwithstanding the foregoing, if the Participant is a director or executive officer of the Company (within the meaning of Section 13(k) of the U.S. Securities and Exchange Act of 1934, as amended), the Participant shall not be eligible for a loan as described above. In the event that the Participant is a director or executive officer and the amount of any income tax is not collected from or paid by the Participant by the Due Date, the amount of any uncollected tax liability may constitute a benefit to the Participant on which additional income tax and National Insurance contributions ("NICs") may be payable. The Participant understands that he or she will be responsible for reporting any income tax and NICs due on this additional benefit directly to HMRC under the self-assessment regime and for reimbursing the Company or the Employer, as applicable, for the value of any NICs due on this additional benefit.

1. <u>Annual Operational Performance Vesting</u>. Effective as of the last day of each of the Company's fiscal years 2026-2030 there shall become vested the percentage of shares covered by the Option which is equal to the Annual Amount (as described below). The Options shall become vested and exercisable as of the date that the Administrator verifies the AOP (as defined below); provided, however, the vesting hereunder will be effective as to Participant as of the end of the fiscal year to which such Annual Amount relates (notwithstanding any termination of Participant's employment during the period between the end of such fiscal year and the verification of the AOP and, in such case, notwithstanding the provisions of Section 3.1(b)). For each such fiscal year, the Administrator shall verify the AOP, and shall notify the Company's Chief Executive Officer of its determination with respect thereto, within ten business days after the Administrator receives the Company's audited financial statements for that fiscal year.

X. For each year (the "Performance Year"), the Annual Amount is zero if the Annual Operational Performance per Diluted Share ("AOP")<sup>2</sup> with respect to such year is less than the amount indicated for such year in column (C). Otherwise the Annual Amount shall be equal to the amount indicated for such year in column (B) plus the product of (a) the excess of (1) the amount indicated for such year in column (D) over (2) the amount indicated for such year in column (B) and (b) the ratio of (1) the excess of (x) the AOP with respect to the year (but not more than the amount indicated in Column (E) for such year) over (y) the amount indicated for such year in column (C) to (2) the excess of (x) the amount indicated for such year in column (E) over (y) the amount indicated for such year in column (C).

Y. In calculating the AOP in Section X above for any Performance Year there shall also be taken into account any AOP in any of the two prior Performance Years (starting in fiscal year 2026) which was in excess of the amount indicated in Column (E) for such prior year and has not previously been taken into account hereunder but only if doing so would increase the Annual Amount in such Performance Year; provided, however that the excess applied

<sup>2</sup> As of a given date, the Company's "Annual Operational Performance per Diluted Share" shall mean the ratio of (1) the excess of (a) the product of (i) EBITDA and (ii) the Fixed Market Multiple (as defined below) over (b) Net Debt to (2) the Company's number of Diluted Shares as of such date, where "EBITDA," "Net Debt" and "Diluted Shares" have the meanings set forth in the Stock Option Agreement set forth on <u>Exhibit A</u>. For purposes of this <u>Exhibit B</u>, the Fixed Market Multiple shall mean 12.15, as adjusted for the weighted EBITDA multiple of future acquisitions as determined by the Committee.

------

under this Section Y and Section Z below shall be limited in any given year to $100. If the Participant is subsequently awarded options vesting in 2031 and 2032, any AOP during 2029 and 2030 in excess of the amount indicated in Column (E) (and not previously taken into account hereunder) may be used in one or more of the next two following years by treating such excess as AOP in the Performance Year under the option agreement granting said options; provided, however that the excess applied in this sentence shall be limited in any given year to $100.

Z. If the Annual Amount in any Performance Year is less than the amount indicated in column (D) for such year then an amount equal to the excess of (1) the amount indicated in column (D) for the applicable Performance Year less (2) the actual Annual Amount for such Performance Year (the "Shortfall Amount") may vest in one or more of the next two following years. If there is an excess of AOP in one or more of the next two following years, such excess can be applied up to the Shortfall Amount not to exceed the amount indicated in column (E) for the Performance Year to which the Shortfall Amount relates; provided, however that the excess applied under this Section Z and Section Y above shall be limited in any given year to $100. The portion of any excess AOP amount which is so used may not be used more than once.

2. <u>Adjustments of Operational Performance Objectives</u>. The Operational Performance targets specified in this Exhibit B are based upon certain revenue and expense assumptions about the future business of the Company as of the date the Option is granted. Accordingly, in the event that, after such date, the Administrator determines, in its sole discretion, that any acquisition or disposition of any business by the Company or any dividend or other distribution (whether in the form of cash, Stock, other securities or other property), repurchase of securities, recapitalization, reclassification, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Stock or other securities of the Company, issuance of warrants or other rights to purchase Stock or other securities of the Company, any unusual or nonrecurring transactions or events affecting the Company, or the financial statements of the Company, or change in applicable laws, regulations, or accounting principles occurs such that an adjustment is determined by the Administrator to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to the Option, then the Administrator may, in good faith and in such manner as it may deem equitable, adjust the amounts set forth on this Exhibit B (and/or adjust the definitions of EBITDA and Net Debt) to reflect the projected effect of such transaction(s) or event(s) on Operational Performance. Further, in the event that the Company pays a special dividend or repurchases shares, the AOP targets shall be adjusted as determined by the Administrator in accordance with past practice.

1. <u>Annual Operational Performance Vesting</u>. Effective as of the last day of each of the Company's fiscal years 2029-2030 there shall become vested the percentage of shares covered by the Option which is equal to the Annual Amount (as described below). The Options shall become vested and exercisable as of the date that the Administrator verifies the AOP (as defined below); provided, however, the vesting hereunder will be effective as to Participant as of the end of the fiscal year to which such Annual Amount relates (notwithstanding any termination of Participant's employment during the period between the end of such fiscal year and the verification of the AOP and, in such case, notwithstanding the provisions of Section 3.1(b)). For each such fiscal year, the Administrator shall verify the AOP, and shall notify the Company's Chief Executive Officer of its determination with respect thereto, within ten business days after the Administrator receives the Company's audited financial statements for that fiscal year.

X. For each year (the "Performance Year"), the Annual Amount is zero if the Annual Operational Performance per Diluted Share<sup>3</sup> ("AOP") with respect to such year is less than the amount indicated for such year in column (C). Otherwise, the Annual Amount shall be equal to the amount indicated for such year in column (B) plus the product of (a) the excess of (1) the amount indicated for such year in column (D) over (2) the amount indicated for such year in column (B) and (b) the ratio of (1) the excess of (x) the AOP with respect to the year (but not more than the amount indicated in Column (E) for such year) over (y) the amount indicated for such year in column (C) to (2) the excess of (x) the amount indicated for such year in column (E) over (y) the amount indicated for such year in column (C).

Y. In calculating the AOP in Section X above for any Performance Year there shall also be taken into account any AOP in any of the two prior Performance Years (starting in fiscal year 2029) which was in excess of the amount indicated in Column (E) for such prior year and has not previously been taken into account hereunder but only if doing so would increase the Annual Amount in such Performance Year; provided, however that the excess applied under this Section Y and Section Z below shall be limited in any given year to $100. If the Participant is subsequently awarded options vesting in 2031 and 2032, any AOP during 2029 and 2030 in excess of the amount indicated in Column (E) (and not previously taken into account hereunder) may be used in one or more of the next two following years by treating such excess as AOP in the Performance Year under the option agreement granting said options; provided, however that the excess applied in this sentence shall be limited in any given year to $100.

<sup>3</sup> As of a given date, the Company's "Annual Operational Performance per Diluted Share" shall mean the ratio of (1) the excess of (a) the product of (i) EBITDA and (ii) the Fixed Market Multiple (as defined below) over (b) Net Debt to (2) the Company's number of Diluted Shares as of such date, where "EBITDA," "Net Debt" and "Diluted Shares" have the meanings set forth in the Stock Option Agreement set forth on <u>Exhibit A</u>. For purposes of this <u>Exhibit B</u>, the Fixed Market Multiple shall mean 12.15, as adjusted for the weighted EBITDA multiple of future acquisitions as determined by the Committee.

------

Z. If the Annual Amount in any Performance Year is less than the amount indicated in column (D) for such year then an amount equal to the excess of (1) the amount indicated in column (D) for the applicable Performance Year less (2) the actual Annual Amount for such Performance Year (the "Shortfall Amount") may vest in one or more of the next two following years. If there is an excess of AOP in one or more of the next two following years, such excess can be applied up to the Shortfall Amount not to exceed the amount indicated in column (E) for the Performance Year to which the Shortfall Amount relates; provided, however that the excess applied under this Section Z and Section Y above shall be limited in any given year to $100. The portion of any excess AOP amount which is so used may not be used more than once.

2. <u>Adjustments of Operational Performance Objectives</u>. The Operational Performance targets specified in this <u>Exhibit B</u> are based upon certain revenue and expense assumptions about the future business of the Company as of the date the Option is granted. Accordingly, in the event that, after such date, the Administrator determines, in its sole discretion, that any acquisition or disposition of any business by the Company or any dividend or other distribution (whether in the form of cash, Stock, other securities or other property), repurchase of securities, recapitalization, reclassification, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Stock or other securities of the Company, issuance of warrants or other rights to purchase Stock or other securities of the Company, any unusual or nonrecurring transactions or events affecting the Company, or the financial statements of the Company, or change in applicable laws, regulations, or accounting principles occurs such that an adjustment is determined by the Administrator to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to the Option, then the Administrator may, in good faith and in such manner as it may deem equitable, adjust the amounts set forth on this <u>Exhibit B</u> (and/or adjust the definitions of EBITDA and Net Debt) to reflect the projected effect of such transaction(s) or event(s) on Operational Performance. Further, in the event that the Company pays a special dividend or repurchases shares, the AOP targets shall be adjusted as determined by the Administrator in accordance with past practice.

1. <u>Annual Operational Performance Vesting</u>. Effective as of the last day of each of the Company's fiscal years 2026-2027 there shall become vested the percentage of shares covered by the Option which is equal to the Annual Amount (as described below). The Options shall become vested and exercisable as of the date that the Administrator verifies the AOP (as defined below); provided, however, the vesting hereunder will be effective as to Participant as of the end of the fiscal year to which such Annual Amount relates (notwithstanding any termination of Participant's employment during the period between the end of such fiscal year and the verification of the AOP and, in such case, notwithstanding the provisions of Section 3.1(b)). For each such fiscal year, the Administrator shall verify the AOP, and shall notify the Company's Chief Executive Officer of its determination with respect thereto, within ten business days after the Administrator receives the Company's audited financial statements for that fiscal year.

X. For each year (the "Performance Year"), the Annual Amount is zero if the Annual Operational Performance per Diluted Share ("AOP")<sup>4</sup> with respect to such year is less than the amount indicated for such year in column (C). Otherwise the Annual Amount shall be equal to the amount indicated for such year in column (B) plus the product of (a) the excess of (1) the amount indicated for such year in column (D) over (2) the amount indicated for such year in column (B) and (b) the ratio of (1) the excess of (x) the AOP with respect to the year (but not more than the amount indicated in Column (E) for such year) over (y) the amount indicated for such year in column (C) to (2) the excess of (x) the amount indicated for such year in column (E) over (y) the amount indicated for such year in column (C).

Y. In calculating the AOP in Section X above for any Performance Year there shall also be taken into account any AOP in any of the two prior Performance Years (starting in fiscal year 2026) which was in excess of the amount indicated in Column (E) for such prior year and has not previously been taken into account hereunder but only if doing so would increase the Annual Amount in such Performance Year; provided, however that the excess applied under this Section Y and Section Z below shall be limited in any given year to $100. If the Participant is subsequently awarded options vesting in 2028 and 2029, any AOP during 2026 and 2027 in excess of the amount indicated in Column (E) (and not previously taken into account hereunder) may be used in one or more of the next

If the Annual Amount in any Performance Year is less than the amount indicated in column (D) for such year then an amount equal to the excess of (1) the amount indicated in column (D) for the applicable Performance Year less (2) the actual Annual Amount for such Performance Year (the "Shortfall Amount") may vest in one or more of the next two following years. If there is an excess of AOP in one or more of the next two following years, such excess can be applied up to the Shortfall Amount not to exceed the amount indicated in column (E) for the Performance Year to which the Shortfall Amount relates; provided, however that the excess applied under this Section Z and Section Y above shall be limited in any given year to $100. The portion of any excess AOP amount which is so used may not be used more than once.

2. <u>Adjustments of Operational Performance Objectives</u>. The Operational Performance targets specified in this Exhibit B are based upon certain revenue and expense assumptions about the future business of the Company as of the date the Option is granted. Accordingly, in the event that, after such date, the Administrator determines, in its sole discretion, that any acquisition or disposition of any business by the Company or any dividend or other distribution (whether in the form of cash, Stock, other securities or other property), repurchase of securities, recapitalization, reclassification, stock split, reverse stock split, reorganization, merger, consolidation, split-up, spin-off, combination, repurchase, or exchange of Stock or other securities of the Company, issuance of warrants or other rights to purchase Stock or other securities of the Company, any unusual or nonrecurring transactions or events affecting the Company, or the financial statements of the Company, or change in applicable laws, regulations, or accounting principles occurs such that an adjustment is determined by the Administrator to be appropriate in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan or with respect to the Option, then the Administrator may, in good faith and in such manner as it may deem equitable, adjust the amounts set forth on this Exhibit B (and/or adjust the definitions of EBITDA and Net Debt) to reflect the projected effect of such transaction(s) or event(s) on Operational Performance. Further, in the event that the Company pays a special dividend or repurchases shares, the AOP targets shall be adjusted as determined by the Administrator in accordance with past practice.

**EXHIBIT C** 

**STOCK RETENTION GUIDELINES** 

As a condition to receiving the Option grant, Participant acknowledges and agrees to hold a number of shares and/or options with such value and for such period of time as set forth below:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) At all times during Participant's continued employment by the Company, Participant shall hold an aggregate amount of Company equity with a value equal to or greater than $[●] (the "<u>Retention Limit</u>") ***[NEOS ONLY:, one-half of which must be held in stock]***. This Retention Limit will supersede any Retention Limit in any prior dated option agreement between the Company and Participant pursuant to the Plan.

For purposes of this Exhibit C, Company equity shall be equal to (i) the Fair Market Value of any Common Stock held by the Participant plus (ii) the value of vested options then held by Participant, whether granted pursuant to the Plan, the Company's 2014 Stock Option Plan, the Company's 2006 Stock Incentive Plan, the Company's 2019 Stock Option Plan or otherwise, which will be equal to the Fair Market Value of the Common Stock underlying the options over the exercise price.
