RTX's $289 Billion Backlog, Explained

RTX has amassed a $289 billion backlog, fueled by accelerating orders across commercial aerospace and defense. The company projects 2026 adjusted sales of $95 billion to $96 billion, with management emphasizing that backlog expansion hinges on new orders outpacing sales growth.

The backlog represents locked-in future revenue and creates near-term earnings visibility that insulates the business from cyclical weakness. RTX's backlog mix includes high-margin aftermarket services contracts, which generate recurring revenue streams and improve profitability over time. The order book serves as a leading indicator for multi-year revenue trajectory as production and delivery schedules extend into future periods.

Growth in both commercial and defense segments contributed to the backlog build. The commercial aerospace pipeline reflects fleet renewal demand and OEM production ramp, while defense orders capitalize on elevated geopolitical spending. Management's 2026 sales guidance implies roughly 20% revenue growth from current run rates, supported by the existing order book.
