What the Numbers Say It Is Worth
The Fair Value Range
Our framework reads AVOID: it trades at roughly a 7% discount to our $1,221.60 fair value, 22.50% revenue growth.
Fair value range in USD, drawn from the 2026-09-08 screen. The gold marker is the market price at the same screen. A 6.7% margin of safety to the base estimate.
Third-party analyst targets: 19 covering, consensus Buy. The average target sits +29% from the screen price.
Reading the gap · Both our model and the analysts see meaningful upside from here.
Price History & Projections
Where it has been, where the models see it going. History from market close data; projection points are our fair-value estimates and third-party analyst targets, dated to the 2026-09-08 screen.
Fair value and rating are our own model estimates; the Street's range reflects third-party analyst estimates. Analysis, not advice.
The Business, in Plain Words
Aircraft parts maker trips ethical screen first
Every jet that takes off carries invisible parts from companies like this one, the kind that keep flaps moving and engines firing. Revenue climbs at 18 percent with 22 percent margins, yet we pass for two clear reasons.
The valuation offers no margin of safety at current levels, and the ethical screen flags the business activity outright. Analyst targets sit higher, but that does not change the core mismatch.
High multiples in aerospace often mask cyclical swings in defence budgets and supply issues. The ethical failure simply removes any temptation to look past the price.
The risks · The main risks here are ordinary market swings and the chance our fair-value read proves too optimistic.
