Is RTX a Buy? What to Consider in 2026

Last updated June 2026

Short answer

There is no universal answer to whether RTX is a buy; it depends on your thesis, time horizon, and what you already own. Below is the case for RTX Corporation, the main risks to weigh, where the stock trades, and a framework to decide for yourself. This is informational, not a recommendation, and Walnut is not an investment adviser.

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. RTX makes money from original equipment sales and, importantly, from long-tail aftermarket service, spares, and maintenance on engines and systems already in the field, which provides steady, high-margin recurring revenue. It pays a dividend and is a core holding in aerospace and defense indexes. Formed by the 2020 merger of Raytheon and United Technologies and headquartered in Arlington, Virginia, RTX is a defense prime with heavy commercial-aerospace exposure.

The case for RTX Corporation

1. Commercial aftermarket.

RTX earns large, recurring, high-margin revenue servicing the vast installed base of Pratt & Whitney engines and Collins systems. As air traffic grows and airlines fly older fleets longer, spares and maintenance demand rises. This aftermarket annuity is more stable and profitable than original-equipment sales.

2. Defense backlog and missiles.

Elevated global defense spending and conflicts have driven strong demand for Raytheon's missiles, air-and-missile defense (Patriot, NASAMS), and radars, supporting a large multi-year backlog. Allied rearmament and munitions replenishment give the defense segment durable, funded growth visibility.

3. Commercial air-travel recovery.

Recovering and growing global air travel lifts demand for new aircraft and engines across Collins and Pratt & Whitney. A long order backlog at Boeing and Airbus translates into multi-year demand for RTX's avionics, interiors, and propulsion content.

4. Scale and integration.

As one of the largest aerospace and defense primes, RTX benefits from scale, broad program participation, and the ability to invest across both commercial and defense cycles. Diversification across the two markets smooths the inherent cyclicality of each.

The risks to weigh

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. Defense contracts can carry fixed-price exposure, supply-chain and labor pressures, and dependence on government budgets and procurement timing. Commercial aerospace is cyclical and sensitive to airline health, fuel prices, and travel demand. Large pension, warranty, and regulatory liabilities add complexity, and the stock can be hit by single-program problems given its size. Geopolitical shifts cut both ways: they support defense demand but introduce export-control and policy risk. Margins depend on disciplined execution across many long-cycle programs.

Valuation context (as of early 2026)

Revenue (TTM): ~$80 billion
Operating margin: ~10-12%
Backlog: Very large (over $200 billion, commercial plus defense)
Net income (TTM): Several billion dollars
P/E (TTM): ~25x
Dividend yield: ~2%
Free cash flow: Several billion dollars annually
Segments: Collins, Pratt & Whitney, Raytheon

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.

How to decide for yourself

Rather than asking whether RTX is a buy in the abstract, it tends to help to answer four questions:

Thesis: do you believe the case above, and is it still true today?
Time horizon: a single stock can be volatile, so a longer horizon absorbs more of the swings.
Position sizing: a thesis can be right and the sizing still wrong; decide how much of your portfolio one name should be.
Overlap: check whether you already hold RTX indirectly through an index or sector ETF before adding more.
