We read business quality at 38/100 (below-average quality), in the Technology sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: medium).

Over the trailing twelve months, X-FAB Silicon Foundries SE generated revenue of €862M at a net margin of 2.2%. Revenue declined 4.2% year over year. It earns a return on equity of 1.8%. Net debt stands at €286M. Fundamentals as of Jul 18, 2026
