High growth, high valuation

Investors have demonstrated they are willing to pay up for the company's growth, and the stock now trades at 63 times the high end of its adjusted earnings guidance. As such, investors aren't paying for what the company is now, but rather what it will grow into.

It's an essentially compelling proposition because many stocks in the defense industry are facing earnings growth and margin challenges (despite improving end-market demand) as a result of ongoing cost pressures and supply chain difficulties. For example, Boeing, RTX, and Lockheed Martin disappointed investors with margins in their defense businesses.

That said, defense spending is contingent on political decisions and geopolitical events, and AeroVironment's funded backlog at the end of January stood at $463 million compared to an estimated $700 million to $710 million in sales for 2024. As such, its revenue prospects will always be subject to near-term booking conditions.
