price 40% above the AI fair value

The price needs 12.0% growth a year for ten years. The AI thinks 5.0% is achievable, at a 6.0% margin.

X-FAB needs to grow faster than it realistically can to justify its price once you adjust for negative owner earnings and weak returns on reinvested capital. Capacity builds and GaN launches help, but utilization is only 60% and margins remain thin. The market is paying for a recovery that history and peer benchmarks suggest will be slow.
