# TransDigm Group: Business Model & Revenue Engine

## Direct Answer

TransDigm Group reports revenue across 3 business segments in its fiscal 2025 Form 10-K. Power and Control is the largest, with $4.6 billion of revenue (52% of the total), followed by Airframe at $4.1 billion (47%). 63% of revenue came from the United States.

## How Does TransDigm Group Make Money?

No single line supplies a majority of revenue: the largest, Power and Control, is 52%, which spreads TransDigm Group's exposure across several demand drivers. Between fiscal 2024 and 2025, Power and Control grew fastest (+15.0%) and Non Aviation Related Business slowest (-3.0%), so the revenue mix tilts toward Power and Control while that gap lasts.

| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Power and Control | $4.6 billion | $4.0 billion | 51.6% | 15.0% |
| Airframe | $4.1 billion | $3.8 billion | 46.6% | 8.0% |
| Non Aviation Related Business | $160 million | $165 million | 1.8% | -3.0% |

## Where Does TransDigm Group's Revenue Come From?

Regions follow the definitions in the filing; most companies assign revenue by customer location.

| Region | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| United States | $5.5 billion | $5.0 billion | 62.7% | 10.0% |
| Outside the United States | $3.3 billion | $2.9 billion | 37.3% | 13.3% |

## What the Segment Figures Do Not Show

The rows above add up to 100% of TransDigm Group's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.

## Where These Numbers Come From

Every figure on this page is a value TransDigm Group reported in the segment note and revenue disclosures of its Form 10-K filed November 12, 2025 (accession 0001260221-25-000081), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.

Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
