What management said
- •Please see the tables and related footnotes in the earnings release for a presentation of the most directly comparable GAAP measures and applicable reconciliation.
- •First, I'll start off with the usual quick overview of our strategy, a few comments about the quarter, and discuss our fiscal 2025 outlook.
- •TransDigm is an exceptional company, and it has been incredibly rewarding to witness its growth and the value it has created for shareholders.
- •Most of our EBITDA comes from aftermarket revenues, which generally have significantly higher margins and, over any extended period, have typically provided relative stability in the downturns.
- •Lastly, our capital structure and allocation are a key part of our value creation methodology.
- •To do this, we stay focused on both the details of value creation as well as careful allocation of our capital.
- •As you saw from our first earnings release, we had a decent Q3.
- •During the quarter, we saw healthy growth in the revenues for both our commercial aftermarket and defense market channels.
- •Commercial OEM revenues were down this quarter compared to prior year, which Mike will discuss further in his market segment commentary.
- •Suffice it to say, OEM revenue was a limiter for our quarterly performance, but this is only transitory and a lingering effect of the Boeing strike and continued rate ramp challenges at Airbus.
- •Airline demand for new aircraft remains high, and the OEMs have long backlogs.
- •Contributing to the strong Q3 margin is the continued growth in our commercial aftermarket, along with diligent focus on our operating strategy, which is allowing margin performance to expand across all segments.
What went well
- •EBITDA as defined margin reached 54.4% in the quarter, with margin performance expanding across all segments on continued commercial aftermarket growth and disciplined execution of the operating strategy.
- •Total commercial aftermarket revenue grew approximately 6% versus the prior year, with all four submarkets posting positive growth and engine-content units growing into the double digits.
- •Defense market revenue grew approximately 13% versus the prior year, well distributed across businesses and customers, with defense bookings up nicely year-to-date and running well in excess of shipments.
- •Operating cash flow generation was strong at over $630 million in Q3, and the company ended the quarter with a cash balance of almost $2.8 billion.
- •The company signed two M&A transactions, closing Servotronics for about $138 million and agreeing to acquire Siemens Precision from RTX for about $765 million (approximately $350 million of expected 2025 calendar-year revenue).
- •Distributor point-of-sale grew in the double digits on a percentage basis, outpacing the overall commercial aftermarket growth rate.
What went wrong
- •Commercial OEM revenue was down 7% versus the prior year and acted as a limiter on quarterly performance, hurt by the Boeing strike, Airbus rate-ramp challenges, and customer inventory destocking.
- •Full fiscal 2025 sales guidance was lowered (midpoint cut $60 million) on lower-than-expected commercial OEM build rates and destocking.
- •U.S. government defense spending outlays moderated, with the rate of growth slowing from a high-single-digit area to a low-single-digit area.
- •The non-engine passenger segment, the largest bucket within commercial aftermarket, saw more muted growth this quarter, and biz jet and helicopter submarkets showed some timing-driven softness.
- •An investment in net working capital consumed about $100 million in the quarter due to higher receivables and higher inventory planning for Q4.

Q&A summary
Was there a drop-off in aftermarket late in the quarter, and will TransDigm recouple to peer aftermarket growth rates going forward?
Aftermarket growth was about as expected and had been guided to moderate post-COVID; given product mix and roughly 3-4% takeoffs/landings growth, volumes sit about where they should be and well above pre-COVID. TransDigm weighs slightly less toward engine than some peers, though engine was strong (double digits). Management would not forecast specific peer comparisons and deferred next-year guidance to the November call.
Does the reiterated full-year aftermarket range imply a Q4 acceleration, and should commercial OEM snap back in 2026 on easier comps?
Year-to-date aftermarket is up about 10%; Q3 at 6% was lower than the first two quarters, but they sit mid-range and feel good about the high-single to low-double-digit guidance, noting limited forecasting visibility given book-and-ship dynamics. OEM destocking is temporary; Q4 guidance implies a return to positive OEM growth as customer inventory normalizes and comps ease.
Was there a sequential aftermarket decline, and what are distributor point-of-sale trends?
Distributor POS was up double digits on a percentage basis, outpacing the overall 6% aftermarket growth (weighted more toward engine). The commercial aftermarket sequential trend was about flat Q2 to Q3.
What is TransDigm's own supply chain situation, and how exposed is it to the St. Louis (Boeing defense) strike?
Supply chain continues to improve, much better than 12-24 months ago though not yet at 2018-2019 levels, with castings and certain electronic components still pain points. The St. Louis strike is a headwind but far smaller than the Boeing Seattle commercial strike given limited defense OEM exposure; impact depends on duration.
On M&A, do you prioritize engine content, and given low equity valuation, would you sell assets to buy back stock?
All else equal engine assets might look better, but TransDigm can only pursue available targets meeting its ~20% IRR component-focused model. Management is happy to own all 52 operating units and declined to comment on selling assets or others' valuations.
How did the Siemens Precision carve-out from RTX come about, and will there be more such carve-outs?
Management was pleased to win the Siemens Precision carve-out from RTX but could not detail the auction process. The A&D landscape is always shifting, with companies spinning off or breaking up divisions, creating ongoing acquisition opportunities expected to continue for years.
