What dominates the section
- TransDigm is concentrated in aerospace and defense, with commercial exposure tied to aircraft production, flight hours, fleet age and airline profitability.

- The company depends on specialized employees, suppliers, regulatory approvals and U.S. Government and aerospace customers.
The risks most specific to TransDigm Group
- Risks Related to our Strategy
We rely heavily on certain customers for much of our sales
The ten largest customers generated approximately 42% of fiscal 2024 net sales, so reduced purchasing by a major customer could materially hurt results.
- Risks Related to our Strategy
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
Most aftermarket sales lack long-term commitments, while OEM contracts may be terminable on short notice and fixed-price contracts expose TransDigm to cost overruns.
- Risks Related to our Strategy
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
Approximately $24 billion of indebtedness could limit financial flexibility, increase vulnerability to business changes and impair the ability to meet obligations.
- Risks Related to our Strategy
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
Debt service and refinancing depend on generating sufficient cash, which is affected by economic, competitive, legislative and regulatory conditions outside TransDigm’s control.
- Risks Related to our Strategy
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
TransDigm relies on highly trained aerospace employees and executives, facing competition for skilled personnel, hiring challenges and succession risks.
- Risks Related to our Operations
Our business is dependent on the availability of certain components and raw materials from suppliers
Supplier failures, facility destruction, strikes or raw-material and component shortages could disrupt production or increase manufacturing costs.
- Risks Related to our Operations
We are subject to certain unique business risks as a result of supplying equipment and services to the U.S. Government
Supplying U.S. Government defense programs exposes TransDigm to specialized risks involving government contracting, funding, procurement rules and oversight.
- Risks Related to our 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
Selling aerospace products requires FAA, DOD, foreign-government and manufacturer approvals, which could be lost or made more burdensome by tighter regulation.
- Risks Related to Legal and Regulatory Matters
We could be adversely affected if one of our products causes an aircraft to crash
Failure of a TransDigm-designed, manufactured or serviced aircraft product could cause a crash, leading to major injury, death and liability costs.
- General Risks
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
Commercial revenue depends on flight hours, worldwide fleet size and age, out-of-warranty aircraft and commercial airline profitability.

About this page
Item 1A of the 10-K on EDGAR was split into its risk factors and, where the company's previous 10-K is on file, each heading was matched to last year's and the text compared word for word. The headings are the filing's own. The one-line readings and the overview were written by a language model from the text of the new, dropped, and rewritten risks; they refer to risks by position and cannot misquote a heading.
