The Flight Royalty Thesis in One Paragraph

Dylan Jovine’s “America’s Most Powerful Stock + The Flight Royalty Three” presentation rests on a single idea. Commercial air travel and defense spending are both strong, so airlines and militaries are flying their existing planes longer. Older planes need more replacement parts, and those parts are mandated by regulation. The companies that make and certify those parts collect on every plane in the sky, which is where the “Flight Royalty” label comes from.

The presentation gives away one name for free, TransDigm Group, and sells a subscription to Behind the Markets for the other three. Between the free reveal and the three paid picks, the basket spans four distinct businesses: TransDigm, Howmet Aerospace, HEICO, and Mercury Systems.

TransDigm: The Free Reveal

TransDigm Group (NYSE: TDG) is the featured stock, and it is the one Jovine frames as the most powerful. TransDigm is an aerospace aftermarket supplier that has grown by buying up small parts makers and rolling them into one company. It uses debt the way a private equity shop would, borrowing to fund buybacks and special dividends. Its pricing philosophy is “value pricing”: it prices a part by what it is worth to the buyer rather than what it cost to make.

That pricing power has drawn scrutiny. TransDigm faced Congressional hearings over parts carrying margins in the thousands of percent. The financial picture is striking in both directions. Net income rose roughly 150% over seven years, while long-term debt climbed about 100% and interest expense about 80%, leaving the company with negative book value. It trades near 25 to 26 times forward adjusted earnings, which Jovine notes is the cheapest the stock has been since 2018 or 2019, and below 20 times EV/EBITDA. At roughly $1,256.90 per share and a $69.5 billion market cap, it has paid a special dividend in each of the last four years.

Howmet, HEICO, and Mercury Systems

Howmet Aerospace (NYSE: HWM) forges superalloy parts for the hottest section of jet engines and makes specialty airframe fasteners. It carries a $115 billion market cap against about $3 billion in debt, with expected earnings growth above 20% a year and a forward multiple near 50 times. The stock recently traded around $289.18, and Jovine shows it up 109% in his open portfolio since August 2024.

HEICO (NYSE: HEI) runs a Parts Manufacturer Approval business, building FAA-certified copies of other makers’ parts and selling them for less. It is family run with low debt, roughly $2 billion against a $52 billion market cap, and about 65% of its revenue is defense with the rest commercial. It grows in the low-to-mid teens and trades above 50 times forward earnings at around $374.67 per share. Our HEICO stock profile digs into the PMA model in more detail.

Mercury Systems (NASDAQ: MRCY) makes defense electronics, the “classified brains” inside advanced military aircraft. It is a best-match guess rather than a confirmed reveal, with a $6.7 billion market cap, an activist turnaround underway, and orders up 74% in the most recent quarter. It trades near 80 times forward earnings at roughly $111.12 per share.

What the Performance Numbers Mean

The “up 109%,” “up 79%,” and “up 33%” figures Jovine shows are portfolio marks from his own undisclosed entry dates. They are not returns available to a new reader buying today, because Howmet, HEICO, and Mercury Systems all trade at high forward multiples after their runs. The underlying thesis about longer-lived planes and regulation-driven replacement demand is real, but a reader starting fresh is paying today’s prices, not the prices Jovine paid when he opened the positions.

That distinction matters because the commercial half of the argument depends on fleet age. Our commercial aircraft explainer covers why airlines are holding on to older planes and what that means for aftermarket names like TransDigm and HEICO. And for background on the analyst behind the pitch, see our Dylan Jovine profile.

One more thing ties the basket together. All four names earn their returns from parts that are already flying, not from betting on a single new program. TransDigm owns the certified designs, Howmet forges the hottest components, HEICO undercuts them with certified copies, and Mercury Systems supplies the electronics the military cannot easily swap out. That means the thesis is not really a bet on aircraft sales. It is a bet on the installed base, the tens of thousands of planes already in service that keep flying longer and keep needing parts. That is a slower, steadier kind of growth, which is exactly what a name like TransDigm’s special dividend and Howmet’s engine franchise are built to capture.
