The Company had 50 reporting units with goodwill and 47 reporting units with indefinite-lived intangible assets as As of the first day of the fourth quarter of fiscal 2024, 2025, the date of the annual impairment test. The Company identified 14 reporting units to test for impairment using a quantitative test for both goodwill and indefinite-lived intangible assets. Of the 14 reporting units selected for quantitative testing, six reporting units primarily were either a recent acquisition or met certain criteria determined by management. For the remaining eight reporting units, the Company elected to bypass the qualitative analysis and perform a quantitative test considering the length of time since the last determination of baseline fair values. The estimated fair values of each of these reporting units and other indefinite-lived intangible assets were in excess of their respective carrying values. Sensitivity analyses were performed around certain of these assumptions in order to assess the reasonableness of the assumptions and the resulting estimated fair values. As a result of the impairment testing performed as of the first day of the fourth quarter, 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, 2024. 2025.

All of the term loans under our term loan facility and the borrowings under our revolving credit trade receivable securitization facility and the Securitization Facility (the “Securitization Facility”) bear interest at variable rates primarily based on the Term Secured Overnight Financing Rate (“Term SOFR”). Accordingly, if Term SOFR or other variable interest rates increase, increases, our debt service expense will also increase. In order to mitigate the interest rate risk of these variable rate borrowings, we have in the past entered 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. In connection with our existing term loans, we entered into various interest rate swap, cap and collar agreements associated with Term SOFR. 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.

Companies across all industries are facing increasing scrutiny from stakeholders related to environmental, social and governance (“ESG”) matters, including practices and disclosures related to environmental stewardship; social responsibility; diversity, equity and inclusion; and workplace rights. Our ability to achieve our ESG goals, including our goal to achieve our Scope 1 and Scope 2 emissions by the year 2031, and to accurately and transparently report our progress presents numerous operational, financial, legal and other risks, and may be dependent on the actions of suppliers and other third parties and significant technological advancements with respect to the development and availability of reliable, affordable and sustainable alternative solutions, all of which are outside of our control. If we are unable to meet our ESG goals or evolving stakeholder expectations and industry standards, or if we are perceived to have not responded appropriately to the growing concern for ESG issues, our reputation could be negatively impacted. In addition, in recent years, investor advocacy groups and certain institutional investors have placed increasing importance on ESG matters.

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.

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.

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 soldiers, sailors and airmen; and space telescope equipment that helps NASA better understand the universe. We expect to continue to develop new products for military and commercial applications. Our businesses continually seek to provide innovative solutions for our customers and others in the commercial aerospace and defense industries.

Selective Acquisition Strategy. We selectively pursue the acquisition of proprietary aerospace component businesses when we see an opportunity to create value through the application of our three core value-driven operating strategies. The aerospace industry, in particular, remains highly fragmented, with many of the companies in the industry being small private businesses or small non-core operations of larger businesses. We have significant experience among our management team in executing acquisitions and integrating acquired businesses into our company and culture. As of the date of this report, we have successfully acquired 93 businesses and various product lines since our formation in 1993. Many of these acquisitions have been integrated into an existing TransDigm production facility, which enables a higher production capacity utilization, which in turn improves gross profit levels due to the ability to spread the fixed manufacturing overhead costs over higher production volume. In the case of larger acquisitions that consist of multiple product lines, we may pursue opportunities to divest certain acquired operating units that are not in line with our acquisition strategy.
