Hook / Thesis
I'm upgrading HEICO Corporation (HEI) to Buy. The reason is straightforward: the business is delivering durable aftermarket revenue, converting profits to cash at a strong clip, and using disciplined acquisitions to expand addressable markets while preserving margins. The most recent quarter (Q3 fiscal 2025, filed 08/27/2025) shows revenue of $1.148 billion, operating income of $265.0 million and operating cash flow of $231.2 million - a company turning solid GAAP profits into free cash flow even while investing aggressively.
This is an actionable trade: scale in around the current levels (last quote ~ $348.88), add on small pullbacks to $330, place a protective stop under $300 and run a staged target plan out to $500 if the company continues to execute. I outline the math below and lay out catalysts and risks.
Business summary - what HEICO actually does and why the market should care
HEICO is an aerospace and defense supplier that focuses on replacement parts for commercial aircraft and niche components for defense applications. It operates two complementary segments - the Flight Support Group (aftermarket parts, fasteners, repair services) and the Electronic Technologies Group (components for avionics, defense subsystems, simulation). Management's playbook has been clear for years: organic growth in a high‑margin aftermarket business plus disciplined, bolt‑on acquisitions that extend capabilities into adjacent niches.
Why that matters now: commercial aviation demand remains structurally higher than the pandemic trough, increasing flying hours and spares consumption. That drives steady, recurring aftermarket revenue versus the lumpy OEM cycle. HEICO is the largest independent producer of replacement aircraft parts in commercial aerospace, which gives it pricing and mix advantage as airlines prioritize maintenance and part availability.
Numbers that back the thesis
- Q3 fiscal 2025 (period ended 07/31/2025) revenue: $1,147,591,000. This follows Q2 revenue of $1,097,820,000 and Q1 revenue of $1,030,222,000, showing sequential growth across the first three quarters of FY2025.
- Q3 operating income: $265,019,000 - implying operating margin near 23% (265.0 / 1,147.6), which is healthy for an industrial supplier and consistent with mix toward higher-margin aftermarket and electronics sales.
- Gross profit in Q3: $457,157,000 for a gross margin just under 40% (457.2 / 1,147.6), evidence of strong product margins and limited commodity pressure at the component level.
- Net income (parent) Q3: $177,341,000 and consolidated net income: $190,680,000 with diluted EPS of $1.26. Importantly, operating cash flow for the quarter was $231,211,000, exceeding reported net income - a sign of healthy working capital and real cash conversion.
- Investment cadence: net cash flow from investing activities in Q3 was -$357,935,000 - a big outflow driven by acquisitions and capex. This shows the balance between buying growth and maintaining cash generation.
- Balance sheet snapshot (Q3): total assets $8.531 billion, equity attributable to parent $4.141 billion, noncurrent liabilities $3.170 billion. Inventory sits at $1.310 billion (typical for an aftermarket supplier carrying parts and rotable inventories).
Those numbers tell a consistent story: accelerating revenue, robust margins, and operating cash flow that supports M&A without destroying liquidity. Management is taking the cash generated by the aftermarket business, deploying it into tuck‑ins that expand product lines and defense exposure, and maintaining profitability.
Valuation framing (practical)
The dataset does not provide a stated market cap, so I estimate an approximate market value using the latest quote and reported diluted shares. Last quote shows a traded price of $348.88 and the most recent diluted average shares are ~140.95 million (Q3 FY2025). Multiplying gives an estimated market capitalization of roughly $49.2 billion (348.88 * 140.95M). Treat that as an approximation - intraday float and fully diluted share counts can alter the number by several percent.
On that basis, the stock is not cheap in headline terms, but you pay up for durable aftermarket margins and superior free cash flow conversion. Crucially, the company is generating operating cash (Q3: $231.2M) and reinvesting for growth. If we think of valuation relative to cash generation, HEICO's valuation reflects a premium for recurring revenue, a track record of profitable M&A and high gross margins.
If you prefer multiples: Q3 EPS of $1.26 annualized (crudely x4 = ~$5.04) would imply a trailing P/E near ~69x using the current price - again, this is a rough extrapolation and does not account for seasonality or full-year guidance. That premium is acceptable to me given Heico's cash conversion and acquisition optionality, but it raises the bar: continued execution is required to justify the multiple.
Trade plan (actionable)
- Trade direction: Long / Buy.
- Time horizon: Swing to position (3-9 months). Scale into the position; aggressive traders can buy up to the market, conservative traders should wait for pullbacks into 330 area.
- Entry: 1) Scale-in 330-350; 2) Add size on dips toward 310-330 (secondary entry band).
- Initial stop: $300 - a level that protects against a material breakdown and would imply a >10% drop from the mid-entry band. Tighten stops if earnings or macro catalysts miss materially.
- Targets:
- Near-term target (3 months): $390 - (~+12% from 348)
- Medium-term target (6 months): $430 - (~+23%)
- Stretch / position target (12 months): $500 - (~+43%) if M&A continues and margins expand or revenue accelerates materially.
- Position sizing note: given the premium multiple and acquisition risk, keep position size modest (5-7% of equity portfolio) and use stops to control downside.
Catalysts to watch (2-5)
- Continued sequential revenue and margin improvement across FY2025 quarters—management cadence has shown sequential growth: Q1 $1.03B, Q2 $1.098B, Q3 $1.148B.
- Acquisition announcements and the integration story: the company is actively buying complementary businesses (example: the Rosen Aviation deal announced earlier in 2025 expands in‑flight entertainment exposure). Successful tuck‑ins that add low‑capex cash flow will be re‑rated.
- Operational leverage on inventory turn and working capital: if operating cash flow continues to exceed net income (Q3 operating cash flow $231.2M vs net income $190.7M), investors will reward the cash conversion story.
- Macro / industry tailwinds: sustained airline utilization increases spares demand and reduces cyclicality for the aftermarket.
Risks and counterarguments
First, the counterargument: the stock already trades at a premium multiple, and much of that premium is priced for near‑perfect execution from M&A and organic growth. If acquisitions disappoint, integration weakens margins, or macro demand softens, downside can be swift. The valuation requires continued margin stability and healthy free cash flow.
Key risks
- M&A execution risk: HEICO's growth strategy relies on acquisitions. Large or poorly priced deals could dent returns or force equity issuance / higher leverage.
- Valuation sensitivity: The estimated market cap (~$49.2B) implies the stock is sensitive to multiple compression; a small miss in results could translate to a large share price move.
- Working capital and inventory exposure: Inventory is sizable (~$1.31B). If demand falls or obsolescence occurs in certain product lines, earnings and cash flow could be pressured.
- Defense/OEM concentration: While diversified across aftermarket and electronics, specific defense contracts or OEM relationships could shift, and export controls or program funding changes could ripple through revenues.
- Interest rate / macro risk: Rising rates increase the cost of financing acquisitions and can compress investor multiples for industrials with heavy capital deployment.
What would change my mind
I would downgrade the idea if: 1) operating cash flow materially lags net income for two consecutive quarters (which would signal working capital strain or lower quality earnings); 2) management completes a large acquisition that meaningfully dilutes margins or requires heavy financing at unfavorable rates; or 3) the company issues guidance that implies a sustained slowdown in core aftermarket demand.
Conversely, I will add conviction (and increase targets) if HEICO continues to grow revenues sequentially, maintains or expands operating margin above ~22%, and demonstrates that acquisitions are accretive to EPS and free cash flow within the first 12 months post‑close.
Final take
HEICO is a high‑quality aerospace aftermarket compounder: sticky demand, attractive margins, and a management team that has repeatedly grown the company via tuck‑ins. The financials show the business generating strong operating cash flow (Q3: $231.2M) even while funding acquisitions (-$357.9M investing). That combination - organic aftermarket durability plus disciplined M&A - is why I'm upgrading HEI to Buy as a trade with defined entries, stop and targets.
If you believe in steady airline utilization, the premium multiple is defensible given HEICO's cash conversion. If you prefer lower valuation risk, wait for a pullback into the 310-330 band and use the $300 stop. For active traders, scale in and manage position size; for longer‑term investors, monitor cash conversion and M&A discipline as the primary readouts of execution.
