Please see the tables and related footnotes in the earnings release for a presentation of the most directly comparable GAAP measures and applicable reconciliations. Second, make a few comments about the quarter, and third, discuss our fiscal 2026 outlook. 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 earnings release, we delivered another solid quarter with Q3 results exceeding expectations. During the quarter, we saw healthy growth in revenue, both sequentially and compared to the prior year in all three of our market channels, commercial OEM, commercial aftermarket, and defense. Further, given the strong performance seen to date as well as our current expectations for Q4, we raised our commercial aftermarket guidance for the year.

Note that we are seeing this healthy growth despite the overall decline in RPMs arising from the conflict in the Middle East, from which we have yet to see any material impact. Lastly, our defense end market saw a double-digit revenue increase this quarter and continues to build backlog that will drive growth as we finish fiscal 2026 and head into our fiscal 2027. Our EBITDA As Defined margin was 52.8% in the quarter, which includes more than full two percentage points of dilution from recent acquisitions. The sequential margin improvement is in spite of margin headwind of about half a percentage point in the quarter related to the newly acquired Jet Parts Engineering and Victor Sierra Aviation Holdings operating units.

What went well
  • Q3 results exceeded expectations with healthy sequential and year-over-year revenue growth across all three channels (commercial OEM, commercial aftermarket, defense) and organic growth of approximately 13%.
  • TransDigm raised full-year fiscal 2026 guidance, lifting sales by $150 million and EBITDA As Defined by $100 million at the midpoint, to $10.51 billion of revenue (~19% growth) and $5.52 billion of EBITDA (~16% growth).
  • EBITDA As Defined margin was 52.8% in the quarter, an improvement sequentially from Q2 despite more than two points of dilution from recent acquisitions.
  • Commercial transport aftermarket revenue grew 18% year-over-year, prompting a raise to the full-year commercial aftermarket growth outlook to low double digits.
  • Strong cash generation continued with operating cash flow over $700 million and free cash flow of ~$870 million in the quarter; full-year free-cash-flow guidance was raised to ~$2.6 billion, ending Q3 with $2.8 billion of cash.
  • The company deployed ~$980 million on share repurchases in the quarter (~800,000 shares at ~$1,208), $1.8 billion year-to-date, and agreed to acquire Prince & Izant for ~$1.1 billion, with over $10 billion of remaining M&A firepower.
What went wrong
  • TransDigm withdrew from its acquisition of Stellant Systems in mid-July after the DOJ indicated it would challenge the deal, a disappointing outcome (the third of ~100 deals in company history not to close for such reasons).
  • EBITDA margin is guided to step down in Q4 versus Q3's 52.8%, partly reflecting a full quarter of lower-margin newly acquired Jet Parts Engineering and Victor Sierra Aviation units.
  • Recent acquisitions diluted margin by more than two full percentage points, with an additional ~half-point sequential headwind in the quarter from Jet Parts Engineering and Victor Sierra.
  • Freight aftermarket was roughly flat (a little lighter in Q3 than earlier in the year) and net working capital consumed about $160 million of cash in the quarter.
  • Proposed defense 'Right to Repair' legislation is an emerging uncertainty that management declined to assess until it becomes final; net debt-to-EBITDA ticked up to 5.8x.

Earnings Call Themes & Trends

TopicPrevious mentionCurrent periodTrend
M&A strategy after Stellant withdrawalActive pipeline; Stellant pendingWithdrew from Stellant after DOJ challenge (viewed as a one-off HSR market-definition disagreement, not indicative of future deal ability); Jet Parts Engineering and Victor Sierra approvals cleared after Stellant's filing; >$3B of deals year-to-date once Prince & Izant closes; over $10B of M&A firepower remaining.
Prince & Izant acquisitionAgreed to buy the Cleveland-based brazing-alloy and specialty-metal maker for ~$1.1 billion (~$360M of 2026 revenue), highly engineered, mostly aftermarket, serving A&D engine platforms (fuel nozzles, rocket engines), aeroderivative turbine and transportation.
Commercial OEM ramp (Boeing/Airbus)Rising build ratesCommercial transport OEM up 25% on steadily rising Boeing/Airbus rates; bookings outpacing sales; management expects continued strength into Q4 and fiscal 2027 as OEMs march along communicated ramp paths, with a reasonably solid supply chain.
Commercial aftermarket resilienceSteady growthCommercial transport aftermarket up 18% with strength across engine, passenger and interiors; distributor POS up double digits; no material impact yet from Middle East conflict, higher jet-fuel prices or RPM/capacity changes; ~50% of aftermarket books and ships in the same quarter.
Defense demandBuilding backlogDefense up ~11% with bookings up year-over-year and sequentially, outpacing sales; positive global defense-spending environment supporting growth into next year; several innovation-driven new-business wins (touchless lavatory suite, fighter-aircraft battery, UCAV landing-gear actuator, audio control system).
Margin drivers / mix~1-1.5 pt constant-mix improvement offset by dilutionConstant-mix improvement target of ~1 to 1.5 points unchanged; modest (couple tenths) mix headwind from OEM growing slightly faster than aftermarket; >2 points of acquisition dilution the main year-over-year drag; conservatism embedded in Q4 margin guide given early ownership of Jet Parts/Victor Sierra.
Capital allocation prioritiesReinvest, M&A, return capital, (debt paydown unlikely)Priorities unchanged; $980M of buybacks in Q3 ($1.8B YTD) meeting IRR criteria; special dividend under continual evaluation given comfortable midpoint of the 5-7x leverage range.
Right to Repair / branching beyond A&DDeclined to assess still-evolving defense Right-to-Repair legislation (defense is tens/hundreds of thousands of SKUs, mostly commercial-derived); remains focused on aerospace and defense (~95% of revenue) while acknowledging potential to branch into other proprietary/aftermarket industrial markets in the fullness of time.

Q&A Summary

Robert Stallard (Vertical Research) asked whether defense Right-to-Repair legislation could affect TransDigm.
Murphy said the bill is still evolving and would impact a broad base of companies, so TransDigm is not in a position to comment until it becomes law.
Ken Herbert (RBC) asked whether the Stellant DOJ review dampens appetite for defense M&A and about the pipeline.
Lisman called Stellant a one-off HSR market-definition disagreement (the third of ~100 deals not to close), noted Jet Parts and Victor Sierra cleared after Stellant's filing, and said future strategy is unaffected with a busy M&A team across commercial and defense.
Gavin Parsons (UBS) asked why aftermarket strength persists despite the usual lag to flight activity and softer RPMs.
Murphy attributed near-term visibility to backlog and leading indicators (aftermarket books/ships ~50% in-quarter) while cautioning it is hard to predict several quarters out; Lisman reiterated no material Middle East impact yet.
Sheila Kahyaoglu (Jefferies) asked to parse the 17% aftermarket growth (versus 14% in Q2) by sub-market.
Lisman cited broad-based demand across platforms with particular strength in engine and passenger (the bigger part of aftermarket) and good interiors strength, while freight was strong all year but a little lighter in Q3.
Kristine Liwag (Morgan Stanley) asked about appetite to broaden acquisitions beyond aerospace/defense given the range-bound valuation and size constraints.
Lisman said TransDigm remains primarily focused on A&D (~95% of revenue), has done well north of $3 billion of A&D deals year-to-date, and could branch out in the fullness of time but the bulk of M&A effort stays in the core A&D fairway for now.
David Strauss (Wells Fargo) asked about year-to-date margin performance and the implied Q4 step-down.
Wynne said full-year EBITDA margin guidance rose 20 bps to ~52.5% with Q3 strong at 52.8%, and Q4 reflects conservatism with a full quarter of Jet Parts/Victor Sierra; Lisman added the >2 points of acquisition dilution and early ownership argue against aggressive Q4 margin assumptions.
Myles Walton (Wolfe) asked what Jet Parts Engineering and Victor Sierra contributed relative to the 17% commercial growth.
Lisman said excluding them was only to show the base business's strong aftermarket performance; including or excluding them does not materially change the growth rate, and both are growing a bit ahead of the broader A&D components landscape.
Scott Mikus (Melius) asked whether Prince & Izant's brazing alloys mean higher content on re-engined 737 MAX and A320neo.
Lisman declined to disclose platform-specific content but described Prince & Izant as a good, mostly-aftermarket business with proprietary, customized chemistry serving engine platforms (fuel nozzles, rocket engines) that fits squarely with TransDigm.
Gautam Khanna (TD Cowen) asked how TransDigm prioritizes special dividends versus buybacks absent M&A.
Wynne said both are continually assessed, buybacks must meet the same IRR return criteria, and sitting comfortably at the midpoint of the 5-7x leverage range the company will decide what maximizes shareholder value as it closes the fiscal and calendar year.
Alex Preston (Bank of America) asked about the commercial OE ramp into Q4/FY2027 and supply-chain conditions.
Murphy said TransDigm is excited about rising Boeing/Airbus rates with bookings a good leading indicator, expects continued growth into 2027 in line with OEM plans, and views the broad supply chain as reasonably solid though continually monitored.
Scott Deuschle (Deutsche Bank) asked how many SKUs the defense business sells to gauge Right-to-Repair exposure.
Lisman said the defense business spans tens to hundreds of thousands of SKUs (not just thousands), largely commercial-derived parts sold broadly to U.S. and global customers, and said the company will discuss the legislation more concretely once it takes final form.
