Executive summary
TransDigm designs and makes specialised components for commercial and military aircraft, including actuators, sensors, ignition systems and cockpit parts. Many of its products are proprietary and sole-source, and they are sold to aircraft manufacturers and to airlines and operators needing replacement parts. A large share of revenue comes from the aftermarket. The company also grows by acquiring smaller aerospace businesses and funds many of those deals with borrowed money.
The company reported trailing revenue of $10.0 billion and three-year growth of 17.6% a year. Profitability figures show an operating margin of 46.0% and a return on invested capital of 18%. Its net debt to EBITDA ratio stands at 6.0 times. The dividend yield is 8.1%. The figures are a snapshot of reported results rather than a forecast.
StocksXray gives TransDigm Group INC an X-Ray Score of 51 out of 100 (high confidence), ahead of 53% of the S&P 500 stocks in its sector. Its strongest lens is growth (85) and its weakest is valuation (39).
Our fair value blend is $1,021.70 (range $929.78 to $1,138.27). At $1,139.34 the stock trades 12% above that blend, so the label is "Fair" with medium model uncertainty. Fair value is a range, not a price target.

Every number comes from SEC filings, end-of-day prices and the StocksXray models described on the methodology page. The X-Ray Score ranks each metric against the company's own sector. Fair value blends three models and carries a typical error of about 40%, so treat it as a range. Analyst ratings, price targets and earnings-call summaries are not part of this report.
