3 Aerospace Suppliers That Could Benefit as Aircraft Makers Face Bottlenecks

Strong aerospace and defense demand, highlighted by GE Aerospace's raised guidance, is boosting smaller specialized firms like Ducommun, StandardAero, and HEICO. Ducommun's shares are up 74% year to date on record quarterly revenue and a growing defense business, particularly in missile defense. StandardAero and HEICO show contrasting performance, with StandardAero's stock down despite revenue growth while HEICO gains from acquisitions and rising net income.

An optimistic Q2 earnings report from GE Aerospace NYSE: GE saw the company boost full-year profit guidance amid resilient demand for repairs and spare parts in spite of challenges related to fuel prices and more. This may bode well for the aerospace service industry more broadly, suggesting that companies providing critical services and products may be able to carve out a niche and potentially outperform larger aircraft makers and related firms.

Aerospace and defense demand continues to surge, prompting some investors to flock to lesser-known names in search of companies with the capacity to scale production. Those willing to take on a bit more risk may find that these firms have greater potential for upside than some of the largest companies in the industry.

With a market capitalization of just $2.6 billion, Ducommun Inc. NYSE: DCO is on the smaller side of the aerospace firms on our list. DCO's share price story has been one of fairly steady growth throughout 2026, although a July sell-off has interrupted this momentum somewhat. Still, shares are up 74% year to date (YTD).

Helping drive this growth is the company's pivot toward defense, which now accounts for the majority of its revenue. And when it comes to revenue, Ducommun has thrived: in the latest quarter , the company reported a record $209 million in revenue, up about 8% year over year (YOY) and the fourth consecutive quarter with at least $200 million in sales.

The firm's commercial aerospace business is in the midst of a rebound, with revenue increasing about 18% YOY in the last quarter, and this has helped margins to improve as well. Nonetheless, defense is the biggest business for Ducommun, and missile defense in particular is a standout (with 22% YOY improvement to quarterly revenue).

The recent share price dip may be a buy opportunity as it has helped to temper Ducommun's value metrics, bringing its price-to-sales (P/S) ratio to 3.0. Analysts see modest upside potential and view DCO shares with moderate optimism in the near-term based on four Buy ratings and three Holds .

StandardAero NYSE: SARO is, at $9 billion in market cap, quite a bit larger than Ducommun, but still not approaching the scale of the biggest players in aerospace. The company has had a dramatically different share price trajectory this year compared to DCO—SARO stock is down 5% YTD after multiple rises and falls earlier in the year. Investors looking closely at the company's financials may see this decline as an opportunity. After all, StandardAero reported 13.3% YOY revenue growth in the most recent quarter , the result of durable demand and excellent sales growth for its...
