Appetite was the story. Applied Aerospace & Defense priced its initial public offering on Tuesday at $20 a share, raising $650 million, and when the book closed, the deal was said to have been oversubscribed about ten times. A company that makes solid rocket motor fuselage sections and casings doesn’t usually inspire that kind of buzz. In June 2026, defense hardware will.
The Huntsville, Alabama, firm sold 32.5 million shares at $20 each, a dollar below the top of its $18 to $21 range, which is the kind of price that leaves something on the table for the first day of trading without admitting weakness.
At that level, the company had a market capitalization of around $3.4 billion. It begins trading on the New York Stock Exchange on Wednesday under the symbol AADX.
Applied Aerospace is not a startup disguised as defense technology. It was founded in 1954 and builds the unglamorous middle of the supply chain: flight control surfaces, motor shafts, solid rocket motor casings, the structural parts that other people’s rockets and planes bolt to. Your client list is the key. In addition to Boeing and GE Aerospace, it counts among its buyers Anduril, the autonomous systems company that has become shorthand for the new wave of defense technology.

That combination is what investors were buying. A legacy manufacturer with seven decades of certification history, selling both old and new, is a cleaner bet than a startup promising to reinvent the category. The order book reflected this.
Morgan Stanley and Jefferies led the underwriting, with BofA Securities, RBC Capital Markets, Guggenheim Securities, Baird, Stifel and Wolfe Nomura Alliance also serving as joint underwriters. according to presentations. The original terms targeted around $634 million; the final climb was higher.
The listing lands in a market that has rediscovered hardware. After a decade in which the most valuable technology companies sold software and attention, capital has shifted heavily toward the physical: chips, satellites, launch capacity and the metal that war and space consume.
European defense budgets have increased, the United States has continued to spend, and public market investors who once treated defense as an ESG issue now treat it as a growth sector.
Applied Aerospace is a beneficiary of that rerating rather than a driver of it. Its components have been flying for years. What changed is the multiple the market is willing to pay for them, and the company timed its exit for when the multiple peaked rather than waiting to see if it held up.
The risk of any oversubscribed defense IPO is the same one that threatens the rest of the sector: that the rally has priced in budget growth that politics may not generate, and that a manufacturer trading at a cap of $3.4 billion thanks to the strength of its clients’ logos will be exposed if those clients reduce their orders. The demand for Anduril is real today. The open question is whether it compounds at the rate assumed by the share price.
For now, the tape will respond to the smallest one. A ten-fold covered book usually means a day-one pop, and day-one pop is what every other defense-adjacent company considering the exit will be watching. AADX opens on Wednesday. The line behind is long.
