HEI Stock Outlook 2026: HEICO's FAA-PMA Moat Is Still the Best Deal in Aerospace

HEICO isn’t a spare parts company. It’s a regulatory arbitrage compounder that has spent five decades collecting FAA approvals that cost competitors years to replicate individually. The 40% gross margin on those approvals funds the next acquisition, which generates the next approval set, which funds the next deal.

If that sentence sounds like it describes an above-average business, it does. The question is what premium that business deserves, and whether you’re being offered a reasonable entry price.

The Numbers That Matter First

HEI closed at $309.40 on May 27, 2026. The most recent reported results — Q2 FY2026 — showed net income growing 49% year-over-year with revenue up 25%. These aren’t analyst estimates or projections. They are confirmed reported actuals that represent HEICO’s fifth consecutive year of at least double-digit earnings growth.

Verified Key Metrics — May 2026

Metric	Value
Stock Price (May 27, 2026)	$309.40
Market Cap	~$43.2B
52-Week Range	$256.11 – $361.69
TTM Revenue	$4.91B
TTM Revenue Growth	+18.8%

Annual Dividend	$0.24 (0.08% yield)
Avg Analyst Price Target	$353.15 (+14.1% upside)
Analyst Consensus	Buy (23 analysts)

Two figures deserve particular attention. The 0.08% dividend yield is not a rounding error — HEICO deliberately returns almost no cash through dividends because every dollar not paid out becomes the seed capital for the next acquisition. And the 40.1% gross margin is more characteristic of a software or pharmaceutical company than an aerospace parts manufacturer. That margin exists because HEICO’s products are certified, approved, and legally protected from easy competition.

Understanding the Two-Segment Architecture

HEICO is structured as two distinct businesses that happen to share financial reporting, family ownership, and a common philosophy about competitive moats.

Flight Support Group (FSG): This is where HEICO began, and it remains the core of the company’s story. FSG supplies FAA-PMA certified replacement parts for commercial and military aircraft. Airlines, MRO shops, and fleet maintenance operators buy HEICO parts when they need to replace OEM components during routine maintenance or unscheduled repairs.

The value proposition is straightforward: HEICO’s parts meet the same FAA safety standards as the OEM original, at 30–60% lower cost. The airline’s CFO saves money without taking on incremental safety risk — the FAA has certified both parts to the same standard. For a large airline maintaining hundreds of aircraft over years, the cumulative savings from PMA parts runs into the hundreds of millions of dollars.

FSG’s revenue moves with global air travel. When airlines fly more hours, they generate more maintenance events, which drives parts demand. The post-pandemic normalization of global aviation has been a tailwind for FSG through 2024 and into 2025.

Electronic Technologies Group (ETG): This is the growth engine that has diversified HEICO beyond its core FSG business. ETG makes specialty electronics for defense, medical, and space applications. The product range includes electronic warfare (EW) components, radar subsystems, satellite payload electronics, avionics, and medical imaging components.

ETG’s competitive position is structurally similar to FSG — highly specialized products serving markets where qualification requirements create significant barriers for newcomers — but the defense and medical end markets add revenue stability during aviation downturns.

The space exposure in ETG is worth dwelling on. HEICO doesn’t announce space electronics contracts with fanfare, but ETG components appear in satellite programs, launch vehicles, and space exploration systems. As commercial space expands — driven by SpaceX’s Starlink ecosystem, Amazon’s Kuiper, and the SDA’s military satellite constellation — the demand for flight-qualified electronics that can survive the radiation and thermal stresses of space grows accordingly. ETG is structurally positioned in that supply chain.

The FAA-PMA Moat: How It Actually Works

To understand why HEICO’s competitive position is so defensible, you need to understand specifically what an FAA-PMA approval entails — and why it creates a barrier that compounds rather than decays.

When HEICO wants to manufacture a replacement part for a Boeing 737 hydraulic system, it cannot simply reverse-engineer the OEM part and sell it. It must petition the FAA with a formal Parts Manufacturer Approval application that includes: engineering drawings proving dimensional equivalence, material certifications demonstrating equivalent or superior material properties, testing data showing functional performance under all relevant conditions, and quality management system documentation demonstrating consistent production capability.

The FAA reviews this application, may request additional testing, and either issues or denies the PMA. The process typically takes one to three years per part family and costs hundreds of thousands to millions of dollars depending on complexity. Critically, unlike a patent — which expires — a PMA approval does not have a fixed expiration date. Once HEICO holds an approval, it holds it indefinitely as long as it maintains FAA quality system compliance.

Once approved, the PMA is part-specific and applicant-specific. A competitor that wants to sell the same replacement part cannot use HEICO’s FAA approval. They must apply for their own. This means every part in HEICO’s approved catalog represents a barrier that took HEICO years to clear and that a competitor must clear independently — with their own investment of time and capital.

HEICO has been accumulating these approvals for five decades. The catalog is enormous. Even if a well-capitalized competitor decided to replicate HEICO’s model from scratch, starting with zero PMA approvals, it would take decades and enormous capital investment to build a comparable catalog. During that time, HEICO is adding new approvals while existing approvals generate revenue.

The FAA maintains a publicly searchable database — the Design and Production Approvals (DRS) system — where investors can see PMA holders by part number and aircraft type. Tracking new entries under HEICO’s name is a leading operational indicator that precedes the financial impact by months to years. It’s the kind of primary source check that gives conviction on the moat quality in a way that analyst reports can’t replicate.

This is what a regulatory moat looks like in practice. It’s not a patent cliff — PMA approvals don’t expire on a schedule. It’s not a brand moat — airlines don’t buy parts because they like the name on the box. It’s a compliance catalog that compounds over time, becomes harder to challenge as it grows, and generates revenue from every maintenance event on every aircraft type in HEICO’s approved coverage.

How FAA PMA Certification Compares to OEM Economics

When Boeing or Airbus designs an aircraft, they designate approved suppliers. Airlines are practically bound to buy OEM-approved parts during warranty periods. Once the aircraft ages past warranty — typically 5–10 years post-delivery — the equation changes.

An airline operating a 15-year-old 737NG has no Boeing warranty obligation. It can source parts from any FAA-approved supplier. That is where HEICO’s catalog becomes commercially relevant: the same hydraulic valve, actuator, or cabin component — certified to identical FAA performance standards — at a fraction of the OEM price. Over a fleet of 150 aircraft and a 10-year operating horizon, PMA savings represent a material budget line item.

Boeing and Airbus have pursued various tactics to limit PMA adoption: proprietary parts programs, tighter tier-one supplier agreements, regulatory lobbying. None has materially altered HEICO’s trajectory. The FAA’s mandate is safety certification, not OEM revenue protection. That structural fact favors the PMA model.

The Acquisition Machine: Mechanics and Deal Flow

HEICO’s management narrative — repeated consistently across decades of earnings calls and shareholder letters — is that they are a disciplined acquirer of niche manufacturing businesses in aviation, defense, and medical markets.

The deal profile: typically a private company with 10–30% operating margins, dominant position in a specialized market with fewer than five competitors, revenues between $20 million and $200 million, and a founder-owner who wants to monetize but is concerned about what happens to the culture and employees post-acquisition.

The Mendelson family’s approach to these deals is what makes them different from private equity. They don’t layer on debt. They don’t replace the management team. They don’t consolidate operations to strip costs. They provide capital, HEICO’s regulatory expertise, and access to HEICO’s customer relationships — and then let the acquired company continue doing what made it valuable in the first place.

This approach produces lower immediate returns than an aggressive financial buyer but generates far better long-term results because the acquisition actually performs as a business rather than as a cost-reduction exercise. Founders who’ve sold to HEICO recommend HEICO to other founders. The deal flow is self-reinforcing.

The M&A roll-up mechanics in practice (hypothetical, illustrative):

A 40-person manufacturer of fuel system components for regional jets holds PMA approvals for 15 part numbers. The founder is 68. Revenue is $35 million at 25% operating margins, with the most comprehensive approval catalog in that specific aircraft family niche. HEICO acquires it. The founder stays two years. The operational team stays permanently. HEICO’s regulatory team identifies 8 additional part families in adjacent aircraft types where the same manufacturing competency generates new PMA approvals. Within three years: catalog grows from 15 to 23 approvals, revenue from $35 million to $48 million — no forced restructuring, no staff cuts.

The philosophy is consistent across deals: preserve what made the business valuable, then extend the catalog.

HEI vs. HEI.A: Which Share Class and Why It Matters

HEICO has two NYSE-listed share classes that confuse new investors:

HEI (Common Stock): Full voting rights, one vote per share. Mendelson family maintains voting control because they own a larger percentage of common shares.

HEI.A (Class A Common Stock): Reduced voting rights — approximately one-tenth of a vote per share, depending on the current charter. Typically trades at a 2–5% discount to HEI.

For most individual investors, the voting distinction is academic. Individual shareholders holding a few thousand shares have essentially no influence over corporate governance outcomes regardless of which class they hold. What matters is price — and HEI.A’s persistent discount to HEI represents better value for the same economic exposure.

The dual-class structure is common among founder-controlled compounders — Berkshire Hathaway (BRK.A/BRK.B) and Alphabet (GOOG/GOOGL) use similar architectures. The governance risk is real: if the Mendelson family’s judgment deteriorates, non-controlling shareholders have limited recourse. The mitigating factor is three decades of excellent decision-making. The risk is not imaginary, but it is historically well-compensated.

The practical implication: investors who specifically want to buy HEICO for long-term holding should consider HEI.A unless their broker restricts access. The discount is real money over a 10-year holding period at HEICO’s valuation levels.

Valuation: Making Sense of 55x

The 55x P/E is the number that stops most value investors from looking further at HEICO. It is undeniably expensive relative to most of the aerospace and defense sector. RTX trades around 30x. Lockheed Martin trades around 20x. General Dynamics around 23x. Why would HEICO deserve a 55x multiple?

The answer requires changing the comparison set. HEICO is not a defense prime contractor. It’s a quality compounder — a business that generates high returns on capital, reinvests those returns efficiently, and compounds the result over long periods. The correct peer group is Danaher, Roper Technologies, and Transdigm Group.

Within that peer group, HEICO’s 55x is still a premium but reflects:

• 40% gross margins (significantly above typical industrial companies)
• 30-year track record of consistent double-digit earnings growth
• Organic growth supplemented by disciplined acquisitions
• Conservative balance sheet that doesn’t create existential risk
• Regulatory moat that compounds rather than decays

The practical valuation risk is interest rate sensitivity. In a period of rising rates, the appropriate discount rate applied to HEICO’s future earnings increases, which mechanically reduces the fair value P/E. If rates rise materially and HEI’s P/E compresses from 55x to 40x, that implies a stock price of $224 on current EPS — a 28% haircut with no change in the underlying business.

This is not a catastrophic scenario for a patient investor who bought at $256 (the 52-week low). It would be more painful for someone who bought at $360 (the 52-week high).

PMA Aftermarket Multiples: Why the Premium Has Historical Justification

Aftermarket parts businesses — particularly those with regulatory certification moats — command premium multiples because their revenue is recurring, their margins are structurally high, and their competitive position is difficult to attack. This is a well-established principle in aerospace M&A: when private equity acquires aftermarket parts businesses, they routinely pay 15–20x EBITDA or more, which implies P/E equivalents in the 40–60x range. Public market investors are essentially paying private equity-equivalent multiples for HEICO — which suggests the public market has priced the quality correctly, not that the public market has made an error.

Defense Sector Valuation Comparison

Company	P/E	Gross Margin	Business Model
HEI	55x	40.1%	Parts + specialty electronics compounder
TDG	~39x	~50%+ EBITDA	Proprietary OEM parts, high leverage
CW	~54x	~mid-20s%	Naval nuclear + defense electronics
RTX	~30x	~20%	Engine systems + Raytheon missiles
LMT	~20x	~12%	F-35 + missiles + space systems
NOC	~25x	~18%	B-21 + GBSD + space
GD	~23x	~17%	Submarines + Gulfstream

The 40.1% gross margin is the telling number. No traditional defense prime runs margins anywhere near that on hardware. That margin structure is why HEICO can justify a premium multiple — and why it will likely continue to deserve one as long as the PMA catalog continues compounding.

HEICO vs. TransDigm vs. Curtiss-Wright: A Practical Comparison

These three companies are often discussed in the same breath as defense-adjacent aerospace compounders, but they are not interchangeable. Understanding the distinctions helps investors decide where HEICO fits in a portfolio.

HEICO vs. TransDigm (TDG):

The contrast is almost elegant. TransDigm is the aftermarket’s aggressive pricer — it acquires OEM-exclusive proprietary parts, applies systematic price increases to captive customers who can’t easily switch, and extracts 50%+ EBITDA margins on the proceeds. The leverage is significant: TDG carries substantial debt as a structural feature of its private-equity-style capital model.

HEICO is the aftermarket’s cost competitor — it builds FAA-certified alternatives to OEM parts and sells them at a meaningful discount, passing savings to airlines who choose to use them. The gross margins are 40%, not 50%+, but the balance sheet is clean. HEICO’s customers are not captive; they choose HEICO because it saves them money. TDG’s customers are often captive; they use TDG parts because the switching cost exceeds the price premium.

Both approaches work. TDG generates higher per-unit economics in its strongest positions. HEICO generates broader adoption across a larger customer base. For investors, TDG is the higher-margin, higher-leverage option; HEICO is the more conservative alternative with similar compounding mechanics but less tail risk.

HEICO vs. Curtiss-Wright (CW):

CW operates in a fundamentally different part of the aerospace and defense ecosystem. Its Naval & Power segment supplies nuclear propulsion control systems for Columbia-class submarines — revenue driven by multi-decade government contracts with almost no political cancellation risk. Its Defense Electronics segment serves airborne and ground platforms. The company also holds option value in small modular reactors through prototype work with X-energy’s Xe-100 program.

CW’s revenue is driven by government program timelines. HEICO’s FSG revenue is driven by commercial airline maintenance cycles. This creates different risk profiles: HEICO is more exposed to aviation demand shocks; CW is more exposed to government budget timing and program schedule slips. Both trade around 50x earnings, reflecting genuine compounding quality in their respective niches, but they are not substitutable positions in a portfolio.

The portfolio construction implication: holding all three (HEI, TDG, CW) gives exposure to complementary aerospace defense compounders with different moat types, different leverage profiles, and different sensitivity to macro variables.

Three Investment Scenarios

Bull Case — Aviation growth sustains, ETG defense wins accelerate

Global air travel continues recovering toward and beyond pre-pandemic highs. Airlines and MRO operators increase maintenance budgets, driving FSG volume. ETG wins incremental defense electronics contracts in electronic warfare and radar as DoD modernization budgets expand. HEICO completes two to three acquisitions per year at its typical 15–20x EBITDA multiples, expanding addressable market.

Revenue growth sustains at 15–20% annually. EPS approaches $7.00 by FY2027. Stock reaches $380–420 as analysts revise targets upward. This is the case where buyers at $309 look correct.

Base Case — Steady compounding, gradual re-rate toward target

Revenue growth of 10–12% annually, driven by organic FSG growth and one to two acquisitions per year. P/E remains in the 50–55x range, reflecting continued premium for HEICO’s moat quality. EPS of $6.20–6.50 in FY2027 implies stock price of $310–360 on flat to modest multiple. Analysts’ $353.15 consensus target is achieved over 12–18 months. Dividend remains inconsequential.

Bear Case — Air demand shock meets rate spike

A global recession or pandemic recurrence causes airline maintenance deferrals, reducing FSG demand. Simultaneously, the Fed or other central banks raise rates materially, compressing P/E from 55x toward 40x. EPS of $5.60 at 40x implies $224 stock price — a 28% decline. ETG partially offsets FSG weakness due to defense contract stability. The business does not break, but the multiple does.

This scenario is uncomfortable for current holders but represents the clearest buying opportunity in HEICO’s history for investors who’ve been watching from the sidelines.

Three Reader Profiles: Who Should Own HEICO

The long-term compounder buyer: You’re holding a 10–15 year position and you don’t care what the stock does in the next 18 months. You want a business where the competitive moat improves over time, management has demonstrated multi-decade capital allocation discipline, and the reinvestment opportunity set remains large. HEICO checks every box. The entry price matters but not as much as the holding period. At $309 on a 15-year view, it likely works. At $256 on a 15-year view, it definitely works.

The GARP investor: You want growth at a reasonable price — and 55x P/E makes you uncomfortable enough to wait for better entry. The discipline here is correct. Set a target price based on a multiple you’d own a quality compounder at — say, 42–46x forward earnings — and wait. If the stock pulls back to that level, buy aggressively. If it doesn’t, accept that you missed this one and move on. Chasing premium-multiple compounders out of FOMO rarely ends well.

The valuation skeptic: You think 55x is structurally unjustifiable for any business and that the PMA moat is overstated because OEMs are developing countermeasures. This view is coherent but has been wrong for three decades. The counter-evidence is in the margin history: if OEM pushback were genuinely eroding HEICO’s position, gross margins would compress below 40%. They haven’t. The skeptic’s stop-loss condition — watching for margin compression as the leading indicator of moat erosion — is actually useful risk management. If gross margins drop below 37% for two consecutive quarters, revisit the thesis.

ETG’s Space Industry Exposure

HEICO rarely features in space industry discussions, but ETG has genuine structural exposure. Satellites require electronics that survive launch vibration, thermal cycling from -170°C to +120°C, and cosmic radiation for 10–15 year operational lifetimes. Commercial-grade electronics cannot do this.

ETG supplies radiation-hardened, vibration-qualified components in this category. As commercial satellite constellations expand — Starlink, Amazon Kuiper, SDA military satellites — the demand for flight-qualified space electronics grows with them. HEICO doesn’t disclose specific satellite customers. The structural argument doesn’t require it: more satellites means more demand for exactly what ETG makes. HEICO captures that growth passively, without winning any single major contract.

Risk Taxonomy: What Could Actually Go Wrong

Risk	Rating	Note
Aviation demand shock (FSG)	Real but temporary	ETG defense/medical offsets; pent-up demand drives recovery
OEM competitive response	Real but structurally limited	FAA mandate is safety, not OEM revenue protection
Acquisition target exhaustion	Relevant 10+ year	HEICO’s medical/industrial expansion extends runway
Succession (Mendelson generation)	Low near-term	Eric and Victor in senior operational roles
Dual-class governance	Structural	Non-controlling shareholders have no override mechanism
Rate sensitivity / P/E compression	Real, timing-dependent	55x is long-duration; rising rates compress mechanically

The clearest actionable risk signal: gross margin trend. If HEICO’s gross margin compresses below 38% for two consecutive quarters, that is evidence that either OEM competitive pressure is real or acquisition mix is shifting unfavorably. Everything else in this risk table can be argued around. A sustained margin break cannot.

How to Monitor HEICO as a Shareholder

For investors who own or are tracking HEICO, these are the data points worth checking quarterly:

FAA DRS Database: The FAA’s Design and Production Approvals database is publicly accessible. Searching for HEICO as a PMA holder and tracking new approvals over time gives a leading operational indicator of catalog growth. New approvals generate revenue months to years after issuance, so this is genuine forward-looking intelligence.

FSG Segment Revenue vs. Global RPKs: IATA publishes monthly global airline Revenue Passenger Kilometers. FSG growth should broadly track RPK growth, with some lag for maintenance cycle timing. If RPKs are growing but FSG revenue is flat or declining, that’s a signal worth investigating.

ETG Order Backlog: Defense electronics businesses run on backlogs. ETG’s backlog level and book-to-bill ratio indicate whether defense and space demand is accelerating or decelerating before it hits reported revenue.

Gross Margin Trend: This is the moat indicator. HEICO’s 40% gross margin reflects the value of the PMA catalog and the absence of severe pricing pressure. Structural compression below 38% would be an early warning signal of either OEM competitive response, acquisition mix shift toward lower-margin businesses, or input cost inflation the company can’t pass through.

Acquisition Cadence: HEICO typically announces acquisitions in press releases. The pace, size, and sector focus of acquisitions signals management’s view of available opportunity and current deal pricing in the private market.

Practical Investment Notes

HEI and HEI.A are both accessible through standard US equity brokerage accounts. International investors with US market access can hold either class through most major brokers.

For investors considering a position at current prices ($309 range):

The 52-week low of $256.11 is meaningful. HEICO found significant institutional buying at that level during broader market stress earlier in the 52-week period. That price represents approximately 46x current EPS — still not cheap by industrial standards but historically a decent entry for a 5+ year hold.

Waiting for another $256 opportunity may not be possible if the fundamental business continues compounding at current rates. The counterargument for buying at $309: EPS is likely to be $6.00+ in 12 months, which retroactively makes $309 a ~51x forward purchase. Less comfortable but not unreasonable for HEICO quality.

Bottom Line

HEICO is expensive and has been expensive for a very long time. Investors who declined to pay 35x P/E in 2015 because it seemed too rich missed a decade of substantial compounding. The people who will decline to pay 55x in 2026 for the same reason may miss another one.

That said, buying at 55x is not the same as buying at 35x. The margin for multiple compression is real — a rate spike or sustained aviation downturn could push this stock to $240 without any actual deterioration in the business’s competitive position.

The disciplined approach: identify a target price that feels like genuine value — probably in the $265–285 range where the 52-week low was found — and wait for market dislocations to provide it. If that opportunity doesn’t come in the next 12 months, decide whether the business is compounding fast enough that paying $310–320 still makes long-term sense.

Q2 FY2026’s 49% net income growth confirms the HEICO engine is running at high output. The questions are about price, not about the business. At $309, the answer depends on your time horizon and opportunity cost.
