Among Swoopr's S&P 500 Equal Weight companies, 6 others share that classification; by latest reported revenue, TransDigm Group ranks 1 of 7. A filing classification is a starting point: a company's real competitors depend on its segments, which its 10-K describes. ## How Does TransDigm Group Compare With Its Peers? | Company | Revenue (latest FY) | Revenue growth | Operating margin | Net margin | | --- | --- | --- | --- | --- | | **TransDigm Group (TDG)** | $8.8 billion FY2025 | 11.2% | 47.2% | 23.5% | | [Astronics Corporation (ATRO)](https://www.getswoopr.com/stocks/companies/astronics-corporation/) | $862 million FY2025 | 8.4% | 8.9% | 3.4% | | [Ducommun Incorporated (DCO)](https://www.getswoopr.com/stocks/companies/ducommun-incorporated/) | $825 million FY2025 | 4.9% | -4.3% | -4.5% | | [Loar Holdings Inc.

Select the chart to open it full size.* ## How Does TransDigm Group Rank Among All SEC Filers in Its Industry Code? 7 companies with annual reports in Swoopr's SEC dataset share SIC code 3728 (Aircraft Parts & Auxiliary Equipment, NEC), a wider group than the S&P 500 Equal Weight companies above. Ranks run from 1 (highest) and use each company's latest fiscal year, in U.S. dollars. | Measure | TransDigm Group | Median of filers | Rank | | --- | --- | --- | --- | | Revenue | $8.8 billion | $496 million | 1 of 7 | | Revenue growth | 11.2% | 8.4% | 3 of 7 | | Operating margin | 47.2% | 8.9% | 1 of 7 | | Net margin | 23.5% | 0.0% | 1 of 7 | A SIC code reflects the filer's main business as the SEC records it, so the group mixes companies of very different size; the median is a better guide than the average, and a rank near the top by revenue says nothing about quality. ## Where These Numbers Come From Every figure on this page is a value TransDigm Group reported in its own SEC filings, read from the SEC's XBRL data (accession 0001260221-25-000081 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 7, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary. Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation. ## Frequently Asked Questions ### Who are TransDigm Group's competitors?
