HEICO Corporation (NYSE: HEI / HEI.A) is an underfollowed aerospace and electronics compounder built from hundreds of mission-critical niches. It develops lower-cost FAA-approved replacement parts, repairs aircraft components, and manufactures specialized electronic products used in aviation, defense, space, medical, and other demanding applications. Its record is attractive, but the investment case depends on continued organic innovation, disciplined acquisitions, and a valuation that leaves room for execution risk.
Last reviewed: September 11, 2026. HEICO’s fiscal year ends October 31. The latest available results cover the quarter and nine months ended July 31, 2026.
Two share classes: HEI and HEI.A
HEICO has two publicly traded share classes that are virtually identical economically. Common Stock (HEI) carries one vote per share, while Class A Common Stock (HEI.A) carries one-tenth of a vote. At July 2026 there were approximately 55.2 million HEI shares and 84.5 million HEI.A shares outstanding. Investors should compare liquidity, voting rights, and market price rather than assuming the cheaper-looking ticker offers a different claim on operating economics.
Business model
Flight Support Group
The Flight Support Group (FSG) is HEICO’s larger segment. It designs and manufactures FAA-approved replacement parts for engines and aircraft, distributes parts, and provides repair, overhaul, and specialty services. Airlines and maintenance organizations need reliable components but also want alternatives to original-equipment-manufacturer pricing. Certification, engineering, documentation, and reputation create meaningful barriers for new suppliers.
Electronic Technologies Group
The Electronic Technologies Group (ETG) makes specialized components and subsystems for aerospace, defense, space, medical, telecommunications, and industrial applications. Products can include power supplies, sensors, connectors, microwave devices, batteries, memory products, shielding, and ruggedized electronics. Individual products may be small relative to a customer’s program but essential to performance and qualification.
The common thread is niche importance. HEICO seeks products with high technical requirements, modest program cost, recurring demand, and limited competition. This can support strong margins and pricing while reducing dependence on any single mass-market product.
Latest financial performance
HEICO reported record Q3 fiscal 2026 net sales of $1.413 billion, up 23% from $1.148 billion. Organic sales growth was 14%, showing that acquisitions were not the only growth engine. Operating income rose 34% to $355.2 million and operating margin expanded to approximately 25.1% from 23.1%. Net income attributable to HEICO increased 33% to $235.4 million, while diluted EPS rose to $1.67 from $1.26.
For the first nine months, sales increased 21% to $3.967 billion, operating income rose 30% to $965.5 million, and attributable net income increased 31% to $659.4 million. Diluted EPS was $4.67 versus $3.57. EBITDA, a non-GAAP measure, rose 28% to $1.136 billion.
FSG quarterly sales rose 18% to $947.8 million, including 12% organic growth. Its operating income increased 24% to $245.3 million. ETG sales increased 36% to $483.5 million and operating income increased 55% to $125.6 million. Both segments contributed, reducing the risk that consolidated growth came from one isolated program.
The acquisition model
Acquisitions are a core operating capability, not an occasional event. HEICO typically buys entrepreneurial companies in defensible niches, retains management and meaningful noncontrolling ownership where useful, and gives subsidiaries considerable operating autonomy. The parent supplies capital, strategic support, and a long-term ownership home without forcing every business into a centralized template.
This model can preserve customer relationships and entrepreneurial incentives. It also expands HEICO’s product catalog and creates cross-selling opportunities. Wencor, acquired in 2023, materially broadened FSG’s aftermarket platform. Fiscal 2026 acquisitions continued to contribute to growth; HEICO spent approximately $1.018 billion on acquisitions in the first nine months.
Investors should nevertheless separate acquired growth from organic growth. Rising goodwill and intangible assets reflect capital committed to expected future earnings. At July 31, 2026, goodwill was $4.356 billion and intangible assets were $1.777 billion, together representing roughly 62% of total assets. The model creates value only when acquired cash flows exceed the purchase price and integration or retention risks.
Why the moat may endure
- Certification and qualification: FAA approvals, customer testing, and program qualification make replacement difficult.
- Small cost, high consequence: A component may represent little of an aircraft or defense platform’s cost but be essential to safe operation.
- Installed-base demand: Aircraft fleets and long-lived programs require parts and support for years.
- Customer savings: Alternative replacement parts can reduce airline maintenance cost relative to OEM channels.
- Engineering breadth: Decentralized specialists collectively cover many narrow technologies.
- Acquisition reputation: A long-term, owner-friendly approach can make HEICO attractive to founders who care about continuity.
The moat is not invulnerable. OEMs can respond on price, regulators can change requirements, and customers can qualify competing suppliers. In defense and space, program timing and government budgets matter. HEICO must continuously earn trust through quality and delivery.
Cash flow and balance sheet
Operating cash flow for the first nine months of fiscal 2026 increased 28% to $815.9 million. Capital expenditures were $54.1 million, implying simple free cash flow of approximately $761.8 million before acquisitions. This highlights the core operations’ cash-generating ability, but acquisition spending is economically central and should not be ignored when evaluating total capital deployment.
Total debt was $2.541 billion and cash was $241.0 million at July 31. Net debt was $2.300 billion; trailing net debt to EBITDA was 1.57 times, slightly improved from 1.60 times at October 2025. During Q3, HEICO issued $550 million of 4.95% notes due 2031 and $650 million of 5.40% notes due 2036, using proceeds to repay revolving-credit borrowings. Longer maturities improve funding stability, although interest expense remains a real cost.
Inventory increased to $1.448 billion from $1.295 billion at fiscal year-end. Aerospace supply chains and customer service levels may require strategic inventory, but investors should watch whether inventory and receivables grow faster than organic sales.
Key risks
- Valuation: High expected growth and quality may already be reflected in the share price.
- Acquisition discipline: Competition for quality assets can raise purchase multiples and lower future returns.
- Integration and key-person risk: Decentralized subsidiaries depend on retaining skilled managers, engineers, and customer relationships.
- Aviation cycle: Lower flight activity, airline financial stress, or fleet retirement can reduce aftermarket demand.
- Regulatory and quality risk: Certification failure, defects, recalls, or delivery problems could damage trust.
- Defense and space exposure: Program delays, cancellations, budget changes, and export restrictions can affect ETG.
- Leverage: Continued acquisition spending could raise debt faster than earnings.
- Accounting complexity: Intangible amortization, contingent consideration, and noncontrolling interests complicate comparisons.
- Dual-class governance: HEI.A has only one-tenth vote per share, and family influence is significant.
Valuation framework
HEICO should not be valued on a simple industrial price-to-earnings comparison. Its organic growth, recurring aftermarket exposure, margins, and acquisition skill may deserve a premium, but a premium is not unlimited. Use several lenses.
- Organic operating model: Forecast FSG and ETG organic growth separately, with conservative through-cycle margins.
- Acquisition contribution: Model announced acquisitions but do not assume an unlimited future pipeline.
- Owner earnings: Start with operating cash flow, subtract recurring capex, then consider acquisition spending needed to sustain historical growth.
- Enterprise value: Include net debt and noncontrolling interests when comparing valuation with EBITDA or operating income.
- Per-share value: Account for both share classes, option dilution, and earnings attributable to noncontrolling owners.
- Scenario range: Test lower organic growth, margin normalization, higher financing costs, and valuation compression.
A bull case combines double-digit organic growth, successful integration, continued aerospace demand, and disciplined acquisitions. A base case assumes mid-to-high-single-digit organic growth plus measured acquisitions. A bear case should include weaker aviation demand, expensive deals, margin pressure, and a lower market multiple. The most important question is how much future compounding the current price already assumes.

Bottom line
HEICO has built a rare combination of aerospace aftermarket exposure, specialized electronics, decentralized entrepreneurship, and disciplined acquisition experience. Q3 fiscal 2026’s 23% sales growth, 14% organic growth, and 34% operating-income growth demonstrate genuine operating momentum.
The principal challenge for investors is not finding business quality; it is valuing that quality while accounting for acquisitions, leverage, noncontrolling interests, and dual-class shares. HEICO can remain an excellent company even if the stock produces disappointing returns from an excessive starting valuation. A scenario-based approach and margin of safety are therefore essential.
