Honeywell Aerospace shares sank as much as 26% on 6 August, the day after the company reported second-quarter results that missed Wall Street expectations and sharply reduced its financial outlook for the rest of the year. Reuters reported that by late in the session, the stock was trading near $157 — compared with a closing price of $220.19 on its first day of regular trading just over five weeks ago.

The Phoenix-based maker of aircraft engines, parts and defence systems posted second-quarter sales of $4.52 billion, up 5% year on year, while adjusted earnings per share fell 32% to $1.87. Wall Street had projected $4.6 billion in sales and $1.1 billion in operating profit, according to Barron's. The profit shortfall reflected around $100 million in separation-related costs and inventory charges incurred after the company was spun off from Honeywell Technologies on 29 June.

A painful first report for a freshly independent company

Honeywell Aerospace began trading on the Nasdaq under the ticker HONA in late June, as part of a three-way break-up of one of the last large US industrial conglomerates. At its market debut, the company had projected revenue growth of 7% to 9% for the full year. It has now cut that guidance to 4% to 5%, and forecast annual adjusted earnings per share of $7.60 to $7.90 — well below the analyst consensus of $8.86, according to data compiled by financial data firm LSEG.

“"Demand continues to be really robust. It's really a supply challenge," Chief Financial Officer Josh Jepsen told Reuters.”

The core problem is a shortage of mechanical parts that is limiting how much equipment the company can deliver to aircraft manufacturers, airlines and defence customers. According to Reuters, those constraints are forcing Honeywell Aerospace to prioritise original equipment deliveries to Boeing and Airbus — which carry thinner margins — over its aftermarket business, where it sells higher-margin spare parts and repair services to airlines. Aerospace suppliers typically recoup much of their profit through aftermarket work rather than initial equipment sales.

International contracts deprioritised as domestic defence takes precedence

The supply squeeze is also shaping how the company allocates its limited output across defence customers. Reuters reported that Honeywell Aerospace is currently favouring domestic US defence and space programmes over international contracts, which tend to carry higher margins. For international aerospace procurement offices and airlines outside the United States, this signals potential delays in parts supply and service fulfilment through at least the second half of 2026.

Despite securing $15 billion in lifetime customer wins this year — including major orders from Indian carrier IndiGo and unnamed defence clients — management acknowledged that production recovery will take time. The company's revised guidance assumes output growth in the third and fourth quarters will remain similar to the approximate 4% achieved in the second quarter, rather than accelerating as previously expected.

Analysts sceptical; fix expected to take until 2027

“"Aerospace stocks work on the back of beats and raises not misses and cuts," Wolfe Research analysts wrote in a post-earnings note, adding that "risk skews negative" for the stock near term.”

J.P. Morgan cut its price target on Honeywell Aerospace to $235 from $255, a new Street-low, saying its discount to peers is likely to widen after these results. Jefferies, which maintained the same $235 target, said investors were left puzzled by how a company operating in a booming aerospace market was managing to grow at only 4%. To address the bottlenecks, the company said it is qualifying more than 50 new suppliers now, with 50 more planned in the second half of the year, while tooling investment is set to double between 2025 and 2027. Management was candid that the largest benefits from those efforts are not expected until next year.
