HEI vs RTX: How HEICO and RTX Corporation Compare (2026)

Same yardstick, side by side (as of July 2026). Valuation lined up like this is most meaningful for two names in the same corner of the market, which these are. Figures are approximate; verify before investing.

Reading it: RTX is the cheaper of the two on forward earnings, but cheaper is not the same as better. Pair the valuation with growth (how far the forward P/E sits below the trailing P/E) and risk (beta) before you decide.

The metrics above tell you which is the marginally better business. The bigger risk for most people is not picking the slightly worse stock, it is over-concentrating. HEI and RTX share themes, so owning both, or adding either to what you already hold, can quietly push a large share of your portfolio into one bet.

This is the part a generic comparison page cannot answer, because it depends on what you own. Connect your brokerage and Walnut shows your real, combined HEI and RTX exposure, flags overlap with your existing positions, and tells you if adding one would tip you past a concentration you are comfortable with, read-only by default, with your login staying at your broker.

HEICO Corporation is a diversified aerospace and defense company best known for making FAA-approved replacement parts for commercial jet engines and aircraft. Its Flight Support Group designs and manufactures aftermarket parts that are functionally equivalent to original equipment manufacturer (OEM) parts but sold at lower prices, plus it repairs and overhauls components. Its Electronic Technologies Group makes specialized electronic, microwave, and electro-optical products for defense, space, medical, and other demanding applications. HEICO makes money by selling parts and services that airlines, MRO shops, and defense primes need on a recurring basis, often tied to aircraft flight hours and fleet aging. The company is controlled by the Mendelson family and has a long record of disciplined, acquisition-driven growth, having bought dozens of niche suppliers over the years. Founded in its current form in the 1950s and headquartered in Hollywood, Florida, HEICO is widely regarded as a high-quality compounder in aerospace.

RTX Corporation (RTX), formerly Raytheon Technologies, is one of the world's largest aerospace and defense companies. It operates three businesses. Collins Aerospace supplies avionics, interiors, actuation, and other systems for commercial and military aircraft. Pratt & Whitney designs and manufactures jet engines for airliners (including the geared turbofan) and military aircraft, and earns substantial recurring revenue from servicing its large installed engine base. Raytheon, the defense segment, builds missiles, missile defense systems (including Patriot), radars, and other advanced defense electronics for the US military and allied governments.

Both fit overlapping themes, but they are not interchangeable. The useful comparison is which set of drivers and risks you want exposure to.

• HEI drivers: Aftermarket parts moat; Acquisition-driven growth.
• RTX drivers: Commercial aftermarket; Defense backlog and missiles.

A faster-growing, richer-valued name usually swings harder, so it suits a longer horizon and a higher tolerance for volatility; a steadier, more cash-generative business suits a more conservative or income-minded investor. The honest test is which set of risks you could hold through a drawdown: HEICO trades at a premium valuation that embeds continued high growth, so any slowdown in commercial air traffic, a deep airline downturn, or a pause in its acquisition pipeline could compress the multiple. For RTX, rTX faces program-execution risks, most visibly the Pratt & Whitney geared-turbofan powder-metal inspection issue that forced costly engine removals and weighed on cash.

Growth-minded investors who believe the theme has years to run tend to accept the richer multiple for more upside; value-minded investors lean toward the cheaper forward earnings and steadier profile. Pick HEI if you believe its drivers more; RTX if you believe its. Many investors hold both, but since they share themes, that is a concentrated bet, not diversification. Decide deliberately and check overlap. For the full detail, see the HEI and RTX guides.

HEI. HEICO commands one of the highest valuations in aerospace and defense, reflecting its consistent double-digit growth, high margins, recurring aftermarket demand, and a long record of value-accretive acquisitions. The premium multiple is the market's way of paying up for a proven compounder; it leaves limited room for execution missteps and has historically compressed mainly during broad market or aerospace downturns.

RTX. RTX trades as a large, dividend-paying aerospace and defense blue chip valued on its huge backlog, recurring aftermarket revenue, and dual commercial-defense exposure rather than rapid growth. Its multiple reflects steady, cash-generative franchises balanced against program-execution risk like the geared-turbofan issue, with the dividend and backlog supporting the shares.

Headline figures (approximate, early 2026): HEI shows revenue (ttm) ~$4 billion, operating margin ~22%, net income (ttm) ~$550 million, p/e (ttm) ~55x; RTX shows revenue (ttm) ~$80 billion, operating margin ~10-12%, backlog Very large (over $200 billion, commercial plus defense), net income (ttm) Several billion dollars.

HEI and RTX are related but distinct: same themes, different businesses and risks. Neither wins in the abstract; the right pick is whichever thesis you actually believe, sized so you are not over-concentrated in one theme.
