Based on the last 12 months of reports, through 31 March 2026
The sector median covers every company in the sector on the US market, loss-making ones included.
TransDigm makes aircraft components with no alternative and prices them accordingly.
The company's strategy is unusual and consistent: it buys makers of parts certified for a specific aircraft with no substitutes. Such a part must be bought from it for as long as the aircraft flies — which allows raising price independently of cost.
Most income comes from the aftermarket: a part sells to an airline at overhaul for markedly more than to the aircraft maker on the assembly line. Revenue therefore follows fleet flight hours rather than new-build rates, which is steadier.
The model draws recurring scrutiny over pricing on defence contracts. The company runs with large debt deliberately and, instead of a regular dividend, periodically pays large special distributions.
