Honeywell Aerospace Valuation Falls Amid Defense Spending Surge

Honeywell Aerospace (HONA) shares have dropped more than 21% since its late-June spinoff from Honeywell Technologies, trading at approximately $157 per share as of September 11. This decline follows the company’s decision to trim its full-year organic growth guidance from 7%–9% to 4%–5% and narrow its EBIT target range, actions taken in response to one-time spinoff costs. Despite the reduced earnings expectations, the stock now trades at roughly 21 times forward earnings, a valuation lower than many aerospace and defense peers.

The pullback occurs against a backdrop of increasing fiscal support for the sector. The fiscal 2027 National Defense Authorization Act, passed by the House on July 22, proposes record U.S. military spending of $1.15 trillion. Global geopolitical tensions, including conflicts in the Middle East and Europe, are further driving nations to increase defense budgets. According to GN auto stocks/industrials: defense spending data, this sustained demand supports the long-term revenue visibility for suppliers of mission-critical components.

Q2 Revenue Grows Amid Profitability Drag

In the second quarter, Honeywell Aerospace reported revenue of $4.5 billion, a 5% year-over-year increase. However, earnings per share fell 71% to $0.78, primarily due to the aforementioned spinoff-related expenses. The company adjusted its full-year EBIT forecast downward from a $4.65 billion–$4.75 billion range to $4.35 billion–$4.45 billion. Management attributed this adjustment to transitional costs associated with becoming a standalone entity, which are expected to diminish in future periods.

Backlog Expansion Drives Future Visibility

Order book strength remains a key fundamental support. The company’s backlog grew 9% year-over-year to $18.2 billion in the second quarter, bolstered by $15 billion in new contracts signed during the period. This pipeline is heavily weighted toward defense modernization programs, military avionics upgrades, and next-generation propulsion systems. As a standalone entity, Honeywell Aerospace can now focus its supply chain efforts specifically on meeting this pent-up demand for high-margin repair, maintenance, and overhaul services.

Market Growth Supports Component Demand

Industry projections indicate significant expansion in the core markets serving Honeywell Aerospace. The global aircraft spare parts market, valued at $97.8 billion in 2025, is forecast to reach $160.2 billion by 2034. Simultaneously, the broader defense market is expected to grow from $2.7 trillion in 2024 to $6.38 trillion by 2035. These trends suggest that demand for auxiliary power units, avionics, and flight control systems will remain robust, providing a stable revenue base independent of short-term macroeconomic fluctuations.
