StandardAero (SARO) Q4 2025 earnings review
Massive Cash Unwind Delivers on Promises; Contract Shift Resets 2026 Optics
StandardAero capped off a record 2025 with $308M of Free Cash Flow in Q4, successfully reversing the working capital build that weighed heavily on prior quarters. Q4 Revenue grew 13.5% YoY to $1.6B, driven by accelerating Commercial Aerospace (+21%), though this was masked by a sudden stall in Business Aviation and a reversal in Military revenues due to the U.S. government shutdown. For FY26, management is guiding to $1.40 Adjusted EPS (midpoint), representing strong 18% growth. Note that FY26 revenue guidance implies a deceleration to ~5% growth, but this is an optical artifact of deliberately eliminating $300-$400M in zero-margin material pass-through revenue to structurally improve margins.
🐂 Bull Case
The Q4 FCF generation of $308M proved management's Q3 claim that working capital builds were merely a timing issue tied to supply chain delays. The balance sheet is flush and leverage is down to 2.4x.
The deliberate elimination of $300-$400M in pass-through revenue for 2026 will mathematically elevate EBITDA margins and improve capital efficiency without sacrificing real profit dollars.
🐻 Bear Case
The U.S. government shutdown immediately reversed Military & Helicopter growth to -3.1% YoY in Q4, highlighting exposure to political macro events.
Ramping volume on LEAP and CFM56 programs remains margin-dilutive as the company travels down the learning curve, keeping a ceiling on Engine Services profitability.
⚖️ Verdict: 🟢
Bullish. The company perfectly executed its promised Q4 cash flow unwind. While the 2026 top-line guidance looks optically light, it is driven by a highly accretive strategic decision to shed empty pass-through revenue.
Key Themes
Commercial Aerospace Leading the Charge
Commercial Aerospace revenue growth is accelerating, reaching 21.0% YoY in Q4 (up from 17.8% in Q3). This was driven by robust aftermarket activity and the continued ramp of the LEAP and CFM56 platforms at the DFW Center of Excellence. Management guides for Low-Double Digit to Mid-Teens growth in this segment for FY26.
Ramping Next-Gen Platform Capabilities
Strategic organic investments in next-generation platforms are accelerating. The LEAP program and the CFM56 DFW Center of Excellence are key growth engines, supplemented by CF34 license expansion and the Augusta business aviation facility for HTF-7000 engines. While these programs are currently in a lower-margin introductory phase, they represent massive multi-decade backlogs that will drive long-term structural growth.
Strategic Contract Restructuring Boosts Margins
As previewed in Q3, management is aggressively improving earnings quality by eliminating $300-$400 million in zero-margin material pass-through revenue starting in FY26. While this optically depresses FY26 revenue guidance to mid-single digits, it acts as a primary driver for structural margin expansion, elevating reported EBITDA margins and improving free cash flow conversion.
Government Shutdown Derails Military Growth
A clear macro headwind emerged as the Military & Helicopter segment suddenly began reversing course, shrinking 3.1% YoY in Q4 after growing 21.1% in Q3. Management explicitly attributed this to maintenance delays caused by the U.S. government shutdown. This highlights the segment's vulnerability to political gridlock and requires monitoring to see if the deferred work recovers in early 2026.
Business Aviation Stalls
Business Aviation growth decelerated sharply to flat YoY in Q4, a stark contrast to the 28.0% surge witnessed in Q3. Management cited 'timing of shipments' as the primary cause. While FY26 guidance assumes a return to high-single-digit growth, this sudden air pocket warrants scrutiny.
Margin Contraction in Component Repair Services
Despite the overall narrative of a record 2025 and full-year margin expansion, the highly profitable Component Repair Services (CRS) segment showed sequential weakness. Q4 adjusted EBITDA margin dropped to 26.6% from 30.7% in Q3. The military shutdown contributed to lower revenues in this segment, resulting in a negative mix shift that temporarily derailed the margin expansion story.
Other KPIs
Stable and improving. The leverage ratio dropped to 2.4x at year-end, down from 3.1x in 24Q4 and 5.4x in 25Q2 prior to the IPO. The balance sheet is now comfortably within the company's long-term target range of 2.0x-3.0x, providing substantial dry powder for strategic M&A and organic facility expansions.
Reversing. Following negative operating cash flows in the first half of the year due to inventory and contract asset build-ups, Q4 delivered a massive positive inflection. This cash surge demonstrates the business's underlying cash generation capability once supply chain bottlenecks clear.
Guidance
Accelerating. The midpoint of $1.40 implies ~17.6% YoY growth from FY25's $1.19. This confirms that while the pass-through revenue elimination dampens top-line optics, bottom-line earnings power is expanding robustly.
Decelerating on a reported basis. The midpoint implies ~4.7% YoY growth, significantly lower than the 15.8% achieved in FY25. However, this is largely an optical artifact; adding back the $350 million midpoint of eliminated zero-margin pass-through revenue yields an implied normalized growth rate closer to 10.5%.
Decelerating slightly. The midpoint of $887.5M implies ~9.8% YoY growth, down from 17.0% in FY25. This reflects a more normalized growth environment following the massive post-IPO catch-up year, while margins structurally improve due to the contract restructuring.
Accelerating. Implied margins at the midpoint (based on segment EBITDA and revenue guidance) reach ~13.8%, a clear step up from the 13.2% recorded in FY25. This reflects the mathematical benefit of the pass-through revenue elimination and gradual learning curve improvements on the LEAP and CFM56 platforms.
Key Questions
Military Revenue Recovery
With the U.S. government shutdown resolved, do you expect to fully recapture the delayed Military & Helicopter maintenance revenue in Q1 2026, or is some of that work permanently lost?
Margin Inflection Timing
As the LEAP and CFM56 programs scale, are you still confident in crossing the profitability threshold for these platforms in early 2026 as previously stated?
Future Pass-Through Reductions
Are there any further opportunities to eliminate zero-margin material pass-through revenues in 2027 and beyond, or was the $300-$400 million a one-time structural reset?
