Is Soitec (ENXTPA:SOI) Fully Priced Following Its Raised Fiscal 2027 Revenue Guidance?

Soitec (ENXTPA:SOI) raised its earnings guidance for the second quarter of fiscal 2027, telling investors it now targets about 50% year-on-year revenue growth instead of the previously flagged more than 30%.

Soitec shares trade at €141.15 after a 3.37% one-day share price return and a 10.02% seven-day share price return, adding to a very large year-to-date share price gain of about 4.7x that appears linked to the upgraded revenue outlook. However, the three-year and five-year total shareholder returns, down 11.37% and 29.25% respectively, show that longer-term holders have experienced a very different journey.
