RTX (RTX): Valuation Check After New F135 Sustainment and Iron Dome Contracts

RTX has caught investors attention after its Pratt and Whitney unit landed a $1.6 billion F135 sustainment contract and its Iron Dome joint venture signed a separate $1.25 billion missile supply deal with Israel.

See our latest analysis for RTX.

These contracts land at a time when RTX is already back in favor, with the share price at $168.8 and a strong year to date share price return of 45.5 percent helping drive a 5 year total shareholder return of 157.44 percent. This suggests momentum is rebuilding after last year’s wobble.

If RTX’s recent wins have you rethinking the whole defense space, it could be worth exploring other aerospace and defense names through aerospace and defense stocks as potential additions to your watchlist.

With RTX trading just under 15 percent below consensus targets after a powerful rally, the key question now is whether investors are still underestimating its long term cash generation or whether the market is already factoring in future growth.

Most Popular Narrative Narrative: 12.9% Undervalued

RTX's most followed narrative sees fair value at $193.79 per share versus the recent $168.80 close, framing the potential upside through defense and aerospace tailwinds.

Robust and growing backlog, highlighted by a 1.86 quarter book-to-bill ratio, $236 billion backlog (up 15% year-over-year), and major new international contracts (e.g., EU, MENA, Asia-Pacific) indicate RTX is well-positioned to benefit from sustained increases in global defense spending and heightened geopolitical tensions, setting up strong visibility for future revenue growth.

Read the complete narrative.

Curious how steady mid single digit growth, rising margins and a rich future earnings multiple can still add up to double digit upside? The narrative breaks down which segment mix, backlog conversion and profitability gains need to align to support that price tag.

Result: Fair Value of $193.79 (UNDERVALUED)

Have a read of the narrative in full and understand what's behind the forecasts.

However, investors still need to watch jet engine reliability costs and any pullback in defense budgets, as both could quickly undermine the bullish outlook.

Another View: What The SWS DCF Model Says
