TransDigm Group INC (TDG)·Q4 2025 Earnings Summary
Executive Summary
- Solid Q4 capstone: TransDigm beat on revenue and adjusted EPS, with net sales $2.44B (+12% YoY) and adjusted EPS $10.82; EBITDA As Defined margin remained structurally high at 54.2% despite mix headwinds . Versus S&P Global consensus, revenue and adjusted EPS were ahead, while reported EBITDA (non-“As Defined”) was slightly below estimates (see Estimates Context).*
- Full-year FY25 outperformed guidance: Revenue $8.83B (+11% YoY) and EBITDA As Defined $4.76B (+14% YoY), both above the high end of the most recent FY25 guide; commercial aftermarket and defense each grew double-digits in Q4; OEM returned to growth after Q3 destocking .
- FY26 initial guide: Revenue $9.75–$9.95B (+11.5% at midpoint), EBITDA As Defined $5.08–$5.23B (+8.2% at midpoint), adj. EPS $36.49–$38.53; margin guide ~52.3% reflects ~200 bps M&A dilution and modest mix headwind (OE/defense) vs FY25 base .
- Capital allocation remains a catalyst: Q4 included a $90/share special dividend (~$5.2B total), $5B new debt, and post-quarter close completion of Simmonds Precision Products (RTX) for ~$765M; buybacks totaled ~$0.5B in FY25 plus ~$0.1B in October .
What Went Well and What Went Wrong
What Went Well
- Broad-based growth and margins: Q4 revenue +12% YoY; EBITDA As Defined margin 54.2% (+160 bps YoY) on sustained aftermarket strength and disciplined operating execution . CEO: “Our EBITDA As Defined margin for the quarter was 54.2%, up approximately 160 basis points... exceptional margin performance” .
- Aftermarket and defense outperformed: Commercial aftermarket +~11% YoY; defense +~16% YoY in Q4; bookings were strong across submarkets and defense outlays supported guidance . POS at distributors grew double digits; inventory in channel reduced by ~0.5 months, indicating healthy sell-through .
- Liquidity and FCF: Operating cash flow in Q4 exceeded $500M, cash ended ~$2.8B; FY25 free cash flow ~$2.4B; interest coverage ~3.2x and 75% of ~$30B gross debt fixed through FY2029 .
What Went Wrong
- OEM softness earlier in year: Commercial OEM revenues were down ~1% for FY25 due to Boeing strike impacts and Airbus ramp challenges; although Q4 returned to +7% growth, the FY trajectory was below initial expectations .
- FY26 margin dilution: Guide embeds ~200 bps EBITDA margin dilution from recent acquisitions and additional ~50–100 bps headwind from OE/defense mix, muting otherwise typical base-business margin expansion .
- Higher interest burden: FY26 interest expense guided to ~$1.9B (weighted avg rate ~6.3%), compressing GAAP net income despite top-line growth and EBITDA As Defined expansion .

Earnings Call Themes & Trends
Management Commentary
- “Our strong fourth quarter finish resulted in surpassing the high end of our most recently issued fiscal 2025 revenue and EBITDA As Defined guidance.” – CEO Mike Lisman .
- “Commercial aftermarket performed well and defense remained robust... commercial OEM revenue increased in the high single digits as we supported higher build rates at the OEMs.” .
- “This guidance includes an additional 200 basis points of margin dilution from recent acquisitions... Adjusting for these... margins would have increased more versus fiscal 2025.” – CEO .
- “Defense sales and bookings can be lumpy... we are going to generally be a little bit more conservative [for FY26].” – CEO .
- “We anticipate capital expenditures of about $300 million in fiscal 2026... >150 new automation projects planned.” – Co-COO Joel Reiss .
- “EBITDA to interest expense coverage... 3.2x... approximately 75% of our $30 billion gross debt balance is fixed through fiscal 2029.” – CFO Sarah Wynne .
Q&A Highlights
- Defense growth sustainability: FY26 defense guide set conservatively (MSD–HSD) given lumpiness despite strong bookings/outlays; company remains competitive on new platforms (e.g., F‑47 content) .
- Margin trajectory ex-M&A/mix: Underlying base business margin expansion remains in the ~100–150 bps range; dilution from Simmonds/Servotronics and OE/defense mix masks this in FY26 .
- OEM destocking largely behind: Management does not expect further destocking headwind in FY26; wider range reflects ramp uncertainty at OEMs .
- Distribution dynamics: Distributor POS up double digits; channel inventory reduced ~0.5 month into fiscal year-end, indicating healthy sell-through .
- Capex and headcount: ~$300M FY26 capex focused on automation and productivity; aim to keep headcount roughly flat while supporting higher OE/defense volumes .
Estimates Context
- Q4 delivered a clean beat on S&P Global revenue and adjusted EPS, modest shortfall on reported EBITDA (not “As Defined”): Revenue $2,437MM vs $2,402.8MM*, Adjusted EPS $10.82 vs $10.05*, EBITDA $1,269MM vs $1,290.7MM* .*
- Prior quarters: Q3 revenue slightly below, adj. EPS slightly below; Q2 revenue modestly below; underscores intra-year volatility from OEM mix/destocking.*
- Implication: Street models likely move higher on FY26 revenue/adj. EPS given initial guide; margin mix and M&A dilution remain key modeling nuances.*
*Values retrieved from S&P Global.
Key Takeaways for Investors
- Durable margin model: Despite OEM/defense mix headwinds and M&A dilution, TDG sustained 54%+ EBITDA As Defined margins; base-business margin expansion remains intact beneath the surface .
- Aftermarket resilience: Double‑digit aftermarket growth and strong distributor POS indicate healthy demand into FY26; watch engines/interiors and regional refurb trends (Asia/Middle East) .
- OEM path improving but uneven: Q4 inflection to +7% YoY with commercial transport bookings >20% supports FY26 guide; ramp execution at OEMs is the key swing factor .
- Capital allocation remains a core alpha driver: Largest-ever $90 special dividend, active buybacks, and disciplined M&A (Simmonds) alongside ample liquidity (~$2.8B cash) underpin flexibility .
- Interest burden a headwind to GAAP EPS: ~$1.9B FY26 interest and ~6.3% weighted average rate compress GAAP net income; adj. EPS growth expected to be modest YoY at the midpoint .
- FY26 setup: Guide embeds conservative defense and OEM assumptions plus M&A/mix dilution; execution on integration (Simmonds/Servotronics) and OEM cadence could unlock upside .
- Monitoring list: OEM monthly rate progress, aftermarket POS/order trends, defense award cadence, integration margin ramps, and capital deployment pacing (buybacks/specials vs pipeline) .
