Hereβs a onepager with the essentials of Heico
Many of you have asked about this, so Iβm considering launching an investment fund based on the principles Iβve shared with you over the years.
To gauge interest and understand potential investments from my readers and followers, Iβve created a short survey.

15-Step Approach
Now letβs use our 15-step approach to analyze the company.
At the end of this article, weβll give Heico a score on each of these 15 metrics.
This results in a Total Quality Score.
1. Do I understand the business model?
At any given moment, roughly 10,000 planes are soaring through the sky.
You have likely been on one this year, which means you have been in contact with Heico.
Heico ensures planes and spacecraft stay in the air by providing vital replacement parts. They are a clear leader in a niche market.
Their product line includes more than 14,000 parts, including engine components, cooling system components, and brake pads.
But thereβs more.
They currently own 98 subsidiaries operating in niche segments of aviation, defense, space, medical, telecommunications, and electronics.
That makes Heico a serial acquirer.
Serial acquirers can offer great benefits:
(If youβre interested in learning more about serial acquirers, click here)
Heico usually buys 80% of the subsidiaries to keep the ownership mindset alive.
They operate in two segments:
The Flight Support Group (68.1%) makes and repairs aircraft parts for commercial, military, and business planes
The Electronics Technologies Group (28.9%) makes and sells advanced electronics for aviation, defense, and other industries
2. Is management capable?
Given the importance of the acquisitions to Heico's growth, we need an exceptional capital allocator at the helm.
In other words, we want people to pay the price for making wrong acquisitions.
This is certainly the case for Heico.
The Mendelson family took control of the company in 1990.
Today, they are still active and hold 16.6% of the shares. For the Mendelsons, Heico isnβt just a business, itβs family wealth. Thatβs like music to my ears. Why you may ask?
Family-run businesses focus on long-term value creation.
Since the Mendelsons took over, Heico has generated a total return of roughly 82,000% (CAGR = 22%). Before them, the CAGR was only 3.2%. It looks like they are doing something right.
But the most impressive part? 400 (!) employees of Heico own more than $1 million worth of Heico stock. Thatβs roughly 4.5% of all employees.
The conclusion? Heico is a great example of an Owner-Operator.
"The stock has turned a lot of ordinary Heiconians, especially early staffers, into millionaires. No, thatβs incorrect, multimillionaires.β - Larry Mendelson

3. Does the company have a sustainable competitive advantage?
Heico has a strong moat.
Airlines love them because Heicoβs parts are cheaper than the original manufacturersβ but work just as well.
This sounds too good to be true, right?
It isnβt! Heico is lazy and very smart at the same time.
The Mendelsons saw an opportunity to expand the product line by reverse engineering existing parts. This clever move saved them from expensive R&D, making them the lowest-cost producer.
Thanks to tough regulations, their moat is even stronger. FAA (Federal Aviation Administration) approval can take years, as safety is the priority. An airline buying cheaper parts from unknown manufacturers invites disaster.
Companies with a sustainable competitive advantage are often characterized by the following:
Gross Margin: 38.9% (Gross Margin > 40%? β)
Return On Invested Capital without Goodwill (ROIC:) 10.0% (ROIC > 15%? β)
At first sight, the Gross Margin and ROIC donβt look attractive.
We will dive into this later in this article.

4. Is the company attractive in an interesting end market?`
Serial acquirers are great at turning money into more money.
Why? There are three big reasons:
There are a lot of new opportunities to invest in
They have smart leaders who know exactly how to use capital
Dual growth engines create more Free Cash Flow (organic growth and new acquisitions)
But thereβs more to it with Heico.
Their specific businesses operate in a great spot because of some exciting trends:
Unfortunately, the world isnβt getting much safer
What is the first thing that people do when they become more wealthy? Traveling
The aviation industry is expected to grow at a CAGR of 4.4%, while the defense industry is expected to grow at a CAGR of 9.8%.
These are attractive growth rates.
5. What are the main risks for the company?
Howard Marks once told the following:
"A gambler bet everything on a race with only one horse. Confident he'd win, he watched as the race began. Halfway through, the horse jumped the fence."
The lesson? In investing, thereβs no such thing as certainty.
Like any business, Heico faces risks:
If the business gets larger, small acquisitions donβt move the needle anymore
High dependence on the Mendelsons
Lack of good reinvestment opportunities
Not being able to get certain parts from the OEMs (Original Equipment Manufacturers) could hurt the performance
OEMs could develop patents or methods that block Heico from making replacement parts
A failure of a part in a plane could cause massive reputation damage
Rich valuation levels (see later)
Serial acquirers counteract some risks by great diversified cash flow streams:
If you break one of the 98 legs off a table, the table will still stand straight. Heico has 98 different revenue streams from its subsidiaries.
6. Does the company have a healthy balance sheet?
We look at three ratios to determine the healthiness of the balance sheet:
Interest coverage: 5.2x (Interest Coverage > 15x? β)
Net Debt/FCF: 3.7x (Net Debt/FCF < 4x? β )
Goodwill/Assets: 44.4% (Goodwill to assets < 20%? β)
The balance sheet doesnβt look ideal. But there are some important nuances:
The interest coverage isnβt so worrisome as Heico has predictable revenue streams
Given the many acquisitions, higher goodwill is normal

7. Does the company need a lot of capital to operate?
The less capital a business needs to operate, the better
Hereβs what things look like for Heico:
CAPEX/Sales: 1.5% (CAPEX/Sales? < 5%? β )
CAPEX/Operating cash flow: 9.3% (CAPEX/Operating CF? < 25%? β )
Itβs great seeing Heico is so capital-light. That means that there is a lot of cash available for new acquisitions.
Now letβs dive into the most important fundamentals of the company.
