Is RTX Stock's Momentum on Growing Jet Engine Demand Sustainable?

RTX Corporation's Pratt & Whitney unit is demonstrating sustained double-digit sales growth, fueled by robust demand across both commercial and military aviation sectors. Surging post-pandemic global air travel and fleet modernization are driving orders for fuel-efficient GTF engines, while heightened geopolitical tensions are boosting military aircraft procurement, exemplified by recent multi-billion dollar engine support contracts. This strong performance has seen RTX shares rise 43.8% over the past year, significantly outperforming its industry, and while 2025/2026 sales are projected to grow, consensus EPS estimates have recently declined.

Analysis

RTX Corporation is exhibiting significant top-line momentum, primarily driven by its Pratt & Whitney jet engine business, which has posted double-digit sales growth for four consecutive quarters, including a 14% year-over-year increase in Q1 2025. This growth is supported by a dual-catalyst environment: a robust recovery in global air travel is fueling commercial demand for fuel-efficient engines like the GTF, which has secured nearly 1,100 orders and commitments, while heightened geopolitical tensions are accelerating military procurement, evidenced by recent contracts worth up to $2.8 billion for its F119 and F135 engine programs. This performance has propelled RTX shares to a 43.8% gain over the past year, substantially outperforming the industry's 14.2% growth. Despite this appreciation, the stock trades at a forward P/E of 23.17X, an 11.6% discount to its industry peers. However, a critical point of concern is the recent downward revision of consensus earnings per share (EPS) estimates for 2025 and 2026, which contrasts with positive sales growth forecasts of 4.2% and 5.8% for the same periods, suggesting potential margin pressure or unforeseen costs.

Key Decisions for Investors

• Given the strong order backlog in both commercial and defense sectors, investors may view the stock's 11.6% valuation discount to its industry as a potentially attractive entry point for long-term exposure to the aerospace upcycle.
• The divergence between projected sales growth and declining consensus EPS estimates is a significant red flag that warrants caution; investors should closely monitor upcoming earnings calls for management's commentary on profitability and cost pressures.
• Considering the stock's 43.8% run-up against the backdrop of negative EPS revisions, a neutral or 'Hold' position may be prudent until there is greater clarity on the company's ability to translate strong orders into bottom-line growth.
