Analysis

Last 4 earnings calls · through Q3 FY2026

TransDigm raised guidance every quarter this year as the aircraft build-rate recovery arrived and the aftermarket reaccelerated. Reported margin still falls, because growth is coming from the cheapest parts of the business. What share of this year's sales growth came from the base business?

  • Guidance has gone up three times this year, on the base business.

    Management said most of the raise came from businesses it already owned, not ones it just bought. Sales growth accelerated every quarter this fiscal year, to 22.5% in Q3 FY2026.

  • The aircraft build-rate recovery finally arrived.

    A year ago commercial OEM sales were shrinking after the Boeing strike; the transport part grew 25% in Q3 FY2026. Management says the destocking is over, so every plane delivered becomes years of aftermarket sales.

  • Buying growth is dragging reported margin down.

    Acquired businesses came in at margins well below TransDigm's own, taking more than two points off FY2026 margin, while low-margin OEM grows fastest. Why did regulators block the Stellant deal, and does it limit future purchases?

Bullish
  • Proprietary aftermarket profit mix
    Most profit comes from proprietary aftermarket parts, so rising flight hours convert into cash without a matching rise in costs or capital spending.
  • Guidance raised every quarter
    Management has raised full-year sales and profit guidance at each of its quarterly updates this year, and says most of each increase came from existing businesses.
  • OEM build rates recovering
    Boeing and Airbus are lifting build rates again and bookings outrun shipments in every channel, supporting the original equipment recovery TransDigm had been waiting for.
Bearish
  • Acquisition margin dilution
    Businesses TransDigm buys arrive with margins well below its own, and management says it does not assume some of them ever reach company margins.
  • Aftermarket growth lags peers
    TransDigm grows its commercial aftermarket more slowly than the wider market, which management ties to thinner engine content and distributor inventory swings.
  • Middle East travel disruption
    A Middle East conflict has reduced flight activity and raised jet fuel prices, and Middle East carriers have cut their requests for quotes sharply.
