RTX Margin Optimism Meets Valuation Wall

What happened

RTX Corporation reported strong second-quarter 2026 results, raised its full-year guidance, and saw its stock rally to around $218. A Seeking Alpha article published on September 28 rates the stock a measured Buy with a two-year target of $222.50, citing margin improvement at Raytheon and Collins as a catalyst to unlock value from the $289 billion backlog. However, the latest DeepValue master report, grounded in SEC filings, maintains a WAIT rating because the shares already trade at 37.9 times earnings and 21.7 times EV/EBITDA, which embeds most of that expected margin expansion. The report also flags persistent supply-chain, tariff, and repair-throughput frictions, particularly in Pratt & Whitney, which could delay backlog conversion and pressure free cash flow. Thus, while the article sees upside, the deeper analysis suggests the stock is fairly priced until execution over the next two quarters confirms that backlog translates into cash.

Implication

The optimistic margin story is plausible but not yet proven; the current price leaves little room for error. Investors should wait for confirmation that Pratt & Whitney’s MRO capacity additions are reducing turnaround times and that Raytheon’s backlog is converting into deliveries without margin leakage. If 2026 free cash flow stays on track for $8.5–$8.75 billion and aftermarket growth remains double-digit, a more constructive stance could be justified. Conversely, any signs of EAC deterioration or tariff impacts on cash flow would validate the WAIT rating and could push the stock back toward the $195 attractive-entry level. Until then, the risk-reward is balanced at best.

Thesis delta

The core investment thesis remains unchanged: RTX owns durable installed-base and missile-defense positions, but the stock is fully valued at current levels. The Seeking Alpha Buy rating introduces a slightly more optimistic view, hinging on margin expansion potential in Raytheon and Collins, but that upside is contingent on execution that is not yet evident in the filings. The primary risk remains Pratt & Whitney’s repair throughput and supply-chain friction, which could turn the backlog into delayed cash rather than incremental profits.
