In this article, we will look at the 10 Undervalued Aerospace Stocks to Buy Now.

On June 27, Jonathan Siegmann, managing director at Stifel covering aerospace and defense, appeared on a CNBC interview to talk about his key insights about the sector. He emphasized that investors should move away from the old legacy defense playbook. According to Siegmann, the defense sector is entering a new growth phase driven by fundamental change.

He noted that, rather than relying on traditional, large-scale, and costly programs, the industry is shifting towards new technologies and more efficient products. Siegmann highlighted that his team initiated coverage on 11 stocks across three segments, focusing on companies investing heavily in innovation and cheaper, more effective defense solutions.

In addition, Siegmann pointed to AI, autonomy, and drones as the core technologies reshaping the sector. He noted that companies investing in leadership of drone technologies have shown impressive growth figures.

Siegmann also discussed the mix between legacy expensive programs and new low-cost technologies. He used Ukraine’s drone attacks as an example of effective low-cost warfare, contrasting them with high-tech US systems used in precision strikes like Midnight Thunder Hammer. He noted some budget cuts in traditional programs, like the F-35, but expects more bipartisan support for drones and next-generation defense tech in the 2026 fiscal budget.

With that, let’s take a look at the 10 undervalued aerospace stocks to buy now.
