|---|---|---|
| A · Speed | 20 / 25 | Nine-month revenue +21.1% (organic +17.0%), Q3 +23.1%, FSG +18% and ETG +28% — the highest speed in its scoring batch, for a mature company |
| B · Moat | 30 / 60 | FAA-approved PMA parts plus a $2,824.8M backlog and a 24.3% operating margin — but the moat is approvals and distribution (B1 6, B2 8), not a platform |
| C · Creative destruction | 11 / 15 | PMA parts breaking the OEM monopoly and cutting airline maintenance costs 30–50%, as the fleet ages to a record 15.2 years — a structural price disruption |

Watch item
Gates: G1 ✓ (confirmed — growth sustained: nine months +21.1%, both segments growing, backlog of $2,824.8M) · G2 ✓ (confirmed — the MRO market extrapolates to ~$236–270B by 2036, 4.6–5.2× the bar). 9 points below the 65-point threshold — first score. No FLAG: deductions of only 5. Watch: whether the acquisition-debt cycle repeats, and whether the margin holds at 40.5% gross as the mix shifts.
Strengths
- High growth: nine-month revenue +21.1% (organic +17.0%), Q3 +23.1%, FY2025 +16.3%
- Backlog of $2,824.8M (72% to be recognised within 12 months)
- Both segments growing: FSG +18.1% and ETG +27.7% (nine months)
- High operating margin: 24.3% for nine months, 25.1% in Q3, nine-month operating cash flow of $815.9M
- Structural demand: the average aircraft age is at a record 15.2 years, pushing PMA demand
Concerns
- Debt rising: total debt of $2,541M, up $373M in nine months on acquisition funding (D1 −2)
- Cyclical growth: tied to the airline boom and defence-budget expansion
- Margin expansion is faint: the gross margin is stable at 40.5% (B4 7)
- Founder-family control: dual-class shares plus ~14.7% Mendelson voting power and brother co-CEOs (D3 −1)
- Acquisition-accounting complexity: nine-month intangible amortisation of $168.8M (D2 −1)
Research notes
Thesis: a mature company growing like a growth company
HEICO enters the BlitzLab record with a first scoring of 56 out of 100, grade C, built from Speed 20 out of 25, Moat 30 out of 60, Creative Destruction 11 out of 15, and deductions of 5. The total sits 9 points below the 65-point line, and the shape of the score is the story: speed converts to 80.0 — the highest in its batch — and creative destruction to 73.3, while the moat converts to 50.0. This is the aerospace-aftermarket company — trailing-twelve-month revenue of about $5,177 million — whose FAA-approved PMA parts break the original-equipment monopoly and cut airline maintenance costs by 30–50%, while the fleet it serves ages to a record 15.2 years. Nine-month revenue grew 21.1%, 17.0% of it organic, and the backlog of $2,824.8 million underwrites the next year.
The gates: both pass — and the deductions are nearly nothing
Gate 1, sustained growth or a second growth curve for a mature company, passes on a confirmed basis. Revenue grew 21.1% in nine months with both segments growing — Flight Support up 18% and Electronic Technologies up 28% — and the backlog covers the forward year. Gate 2, a ten-year market ceiling at least ten times current revenue, passes as a confirmed verdict: the MRO market extrapolates to roughly $236–270 billion by 2036, 4.6 to 5.2 times the bar. The fourth quarter of 2026 has not been reported at T, and its reporting date is unconfirmed — it is not a company-confirmed date and must not be presented as one — and no outcome is anticipated here. That is the balance of the record at T: the cleanest profile in its batch, with deductions of only 5 points, whose single blemish is the debt taken to fund acquisitions — $2,541 million and rising $373 million in nine months.
The business: the aftermarket company that breaks the OEM monopoly
HEICO sells aerospace aftermarket parts and defence and space electronics, and its core idea is simple: a Federal Aviation Administration-approved PMA part that matches the original equipment manufacturer's part at a lower price and a shorter lead time. It is the world's largest manufacturer of FAA-approved PMA parts, excluding the original equipment manufacturers themselves. The company has two segments: the Flight Support Group, serving airlines and maintenance, repair and overhaul shops, and the Electronic Technologies Group, selling defence, space and aviation electronics. Revenue ran from $3,857.7 million in fiscal 2024 to $4,485.0 million in fiscal 2025, up 16.3%, to $3,967.3 million in the first nine months of fiscal 2026, up 21.1% year on year. The average aircraft age has reached a record 15.2 years, and older aircraft need more PMA parts. Trailing revenue is about $5,177 million.
Why it scored 56: the highest speed in its batch
Speed scores 20 of 25, the highest in its batch at 80.0. Growth (A1, 8 of 10) is unusual for a mature company: 21.1% over nine months, 23.1% in the quarter, with both segments growing — Flight Support up 18.1% and Electronic Technologies up 27.7% over nine months. The growth is not acquisition-inflated: excluding $133.5 million of acquired revenue, organic growth is about 17.0%. The two points not awarded are for the cycle — part of the growth rides an aviation boom and expanding defence budgets. Capital speed (A2, 4 of 5) mixes self-generated cash with debt raised on good terms: operating cash flow of $815.9 million in nine months against $638.9 million a year earlier, and $1,191.5 million of senior unsecured notes issued in the nine months. Hiring (A3, 4 of 5) shows revenue growing faster than headcount — about 11,100 employees, up 11.0% year on year. Share speed (A4, 4 of 5) is the PMA story in numbers: aftermarket replacement parts up 16.2% and repair and overhaul up 23.5% over nine months, against a fleet ageing to a record 15.2 years.
The moat scores 30 of 60. Network effects (B1, 6 of 18) are certification and switching-cost effects rather than platform lock: FAA PMA approval is granted part by part, airline and maintenance-shop qualification creates a switching cost, and Electronic Technologies holds many sole-source niches in defence and space electronics. Distribution (B2, 8 of 18) is where certification becomes leverage: consumable parts sold repeatedly to airlines and maintenance shops, with demand tied to flight hours, plus long-term defence and space supply contracts. Market size (B3, 9 of 12) is ample: the aerospace and defence maintenance, repair and overhaul market extrapolates to about $236–270 billion by 2036, 4.6 to 5.2 times the bar of $51.77 billion, while trailing revenue of $5.18 billion is only about 3.6% of the market and growth of 21% is more than three times the market's growth of about 6%. Gross margin (B4, 7 of 12) is solid and stable: a nine-month gross margin of 40.5% and an operating margin of 24.3% — high for manufacturing, middling against software at 60–80%.
Creative destruction scores 11 of 15, and the first and third items carry it. What is being displaced (C1, 4 of 5) is the original equipment manufacturer's monopoly on aftermarket parts: expensive genuine parts with long lead times giving way to FAA-approved PMA parts of equal quality at a lower price and faster supply. HEICO is one of the movement's leaders rather than its sole driver. The behaviour change (C2, 3 of 5) is spreading but not yet irreversible: airlines adopt PMA parts to cut costs, but they could return to original equipment parts if a safety or warranty issue arose. The cost-structure change (C3, 4 of 5) is the value proposition itself: PMA parts are typically 30–50% cheaper than original equipment parts, lowering the operating cost of an ageing fleet at a record 15.2 years.
The risks: five points of deductions, and debt is most of them
The deductions total 5, far below the 15-point FLAG line. Debt (D1, minus 2) is mid-level leverage with comfortable coverage: total debt of $2,541.2 million against cash of $241.0 million, for net debt of about $2,300 million, about 44% of trailing revenue. Interest of $99.6 million over nine months, about $133 million annualised, against annualised operating profit of about $1,287 million gives interest coverage of about 9.7 times. The deduction is for the direction of travel: total debt rose $373 million in nine months on acquisition funding. Revenue quality (D2, minus 1) reflects acquisition accounting complexity: intangible amortisation of $168.8 million over nine months cuts operating profit, though it is a non-cash cost. Governance (D3, minus 1) is a dual-class structure with a family at the top: Class A shares carry one-tenth of a vote, the Mendelson Reporting Group holds about 14.7% of the votes, and brothers Eric and Victor Mendelson are co-chief executives and co-chairs. Regulation (D4, minus 1) reflects dependence on FAA approvals and export controls under ITAR.
What would change the score
HEICO is nine points below the 65 line, and the path up runs through the moat rather than the deductions, which are already small. The clearest lever is Electronic Technologies becoming a second axis equal to Flight Support: it grew 27.7% over nine months and 35.8% in the quarter, against 18.1% for Flight Support. The discipline question is the acquisition-debt cycle: $1,018.2 million of acquisitions in nine months funded largely by debt is sustainable at 9.7 times interest coverage, but if acquisition speed outruns the $815.9 million of nine-month operating cash flow, leverage stacks up structurally. Conversion of the $2,824.8 million backlog is the near-term test.
