RTX (RTX) is back in focus after Raytheon committed US$100 million to expand its Portsmouth, Rhode Island facility, a move tied to higher demand for LTAMDS radar and Patriot GEM-T components.

The Rhode Island expansion comes as RTX’s share price has pulled back 3.62% over the past day to US$185.60, yet still shows a 6.37% 30 day share price return and a 5 year total shareholder return of 138.56%, suggesting longer term momentum remains intact.

With RTX trading at US$185.60, sitting roughly 16% below the average analyst price target and close to narrative fair value estimates, the key question is whether this reflects a genuine discount or a stock for which the market is already pricing in future growth.

Preferred P/E of 34.4x: Is It Justified?

With RTX stock at $185.60 and carrying a P/E of 34.4x, the market is assigning a relatively full earnings multiple, yet comparative data suggests investors are not paying a premium versus similar aerospace and defense companies.

The P/E ratio compares the current share price to earnings per share and is a common way to see how much investors are willing to pay for each dollar of profit. For a company like RTX, with a large installed base across Collins Aerospace, Pratt & Whitney and Raytheon, P/E is often used as a shorthand for what the market thinks about the durability and growth of its earnings.

According to the provided checks, RTX is considered good value based on its P/E of 34.4x versus an estimated fair P/E of 35.5x. It is also assessed as trading at good value compared with both the US Aerospace & Defense industry average P/E of 40.3x and a peer average P/E of 55.8x. That points to a situation where the market is paying up for RTX's earnings, but still at a lower multiple than many direct peers. Some investors may pay attention to this if valuations across the sector converge over time.

Looking at it another way, RTX is flagged as trading at good value relative to peers and industry overall, even though its forecast earnings growth of 9.89% per year is not classified as high and is expected to be slower than broader US market earnings growth. If sector valuations remain clustered around higher P/E levels, the fair P/E estimate of 35.5x gives a reference point that some investors may use as a potential level for where the market could gravitate, depending on how RTX's earnings and balance sheet evolve.

Result: Price-to-Earnings of 34.4x (ABOUT RIGHT)

However, RTX stock still faces risks, including potential program delays or defense budget changes that could challenge current earnings assumptions and reduce support for the price-to-earnings ratio.

Another View on RTX: DCF Says the Market Is Already There

The P/E work suggests RTX stock is roughly in line with a fair ratio, but the SWS DCF model paints an even tighter picture. At $185.60, RTX is essentially level with an estimated future cash flow value of $185.50, leaving little obvious upside or downside from this lens.

When one method points to some relative value and another suggests the price already matches future cash flows, which signal should carry more weight for you as an investor?
