The appetite was the story. Applied Aerospace & Defense priced its initial public offering on Tuesday at $20 a share, raising $650M, and by the time the book closed the deal was said to be about ten times oversubscribed. A company that makes fuselage sections and solid rocket motor cases does not usually inspire that kind of scramble. In June 2026, defence hardware does.
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 pricing that leaves something on the table for the first day of trading without admitting weakness.
At that level the company carried a market capitalisation of about $3.4bn. It begins trading on the New York Stock Exchange on Wednesday under the ticker AADX.
Applied Aerospace is not a startup wearing a defence-tech costume. It was founded in 1954 and builds the unglamorous middle of the supply chain: flight control surfaces, engine shafts, solid rocket motor cases, the structural pieces that other people’s rockets and aircraft are bolted onto. Its customer list is the tell. Alongside Boeing and GE Aerospace, it counts Anduril, the autonomous-systems company that has become shorthand for the new defence-tech wave, among its buyers.

That mix is what investors were buying. A legacy manufacturer with seven decades of certification history, selling into both the old primes and the new ones, is a cleaner bet than a pre-revenue startup promising to reinvent the category. The order book reflected it.
Morgan Stanley and Jefferies led the underwriting, with BofA Securities, RBC Capital Markets, Guggenheim Securities, Baird, Stifel and the Wolfe Nomura Alliance also serving as joint bookrunners, according to filings. The original terms had targeted around $634M; the final raise came in 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 rotated hard toward the physical: chips, satellites, launch capacity, and the metal that war and space both consume.
European defence budgets have climbed, the United States has kept spending, and public-market investors who once treated defence as an ESG problem now treat it as a growth sector.
Applied Aerospace is a beneficiary of that re-rating 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 the moment the multiple peaked rather than waiting to see whether it holds.
The risk in any oversubscribed defence IPO is the same one that haunts the rest of the sector: that the rally has priced in budget growth that politics may not deliver, and that a manufacturer trading at a $3.4bn cap on the strength of its customer logos is exposed if those customers slow their orders. Anduril’s demand is real today. Whether it compounds at the rate the share price assumes is the open question.
For now, the tape will answer the smaller one. A book ten times covered usually means a first-day pop, and the first-day pop is what every other defence-adjacent company eyeing the exit will be watching. AADX opens on Wednesday. The queue behind it is long.
