Honeywell Aerospace (HONA) shares tumbled as much as 23.2% on August 6, 2026, after the newly independent company reported second-quarter results that fell well short of analyst expectations and slashed its full-year guidance, raising fresh concerns about persistent supply chain disruptions and execution challenges.
The aerospace and defense supplier, which completed its separation from Honeywell Technologies in June, posted second-quarter revenue of $4.52 billion, up 5% year-over-year but below the $4.6 billion Wall Street consensus. Operating profit of roughly $1 billion missed estimates of $1.1 billion, declining 7% from a year earlier, partly due to inventory obsolescence charges. Adjusted earnings came in at $1.87 per share.
Investors were particularly rattled by the guidance cut—just weeks after the initial forecast was issued. Honeywell Aerospace now expects full-year organic revenue growth of 4% to 5%, down sharply from its prior 7% to 9% range. Pro forma standalone adjusted EBITDA guidance was lowered to $4.35–$4.45 billion from $4.65–$4.75 billion. CEO Jim Currier cited a need to align guidance with the supply chain’s demonstrated capabilities, noting that material-supply constraints continued to limit sales growth across aerospace end markets.
Analysts pointed to continued operational struggles. Melius Research noted that after a tough first quarter, the second quarter wasn’t much better, with commercial aftermarket sales growing 8% compared with roughly 23% growth at peers. The firm warned that if the company cannot resolve supply-chain issues, it risks losing future high-margin aftermarket revenue to competitor repairs and third-party parts. Vertical Research Partners cautioned that fixing the problems will take time and that Honeywell Aerospace may lag peers due to less exposure to high-growth subsectors.
Shares ended the session down roughly 20%, trading at about 23 times expected 2026 earnings—well below the valuation of GE Aerospace, which recently raised its own guidance. The selloff signaled a sharp reset in expectations, with analysts warning of a potential value trap until execution improves.
