Soitec (ENXTPA:SOI) Faces An AI Valuation Test, Is The Stock Still Undervalued?
Soitec (ENXTPA:SOI) is drawing fresh attention as debate intensifies over whether its recent share performance and AI exposure fairly reflect future cash flow potential in a tougher European semiconductor backdrop.
Over the past year, Soitec has become one of the more debated semiconductor stocks in Europe as its share price return and AI narrative have pulled in different directions at different points. The 1 day share price return of 11.93% at a latest price of €108.35 comes after a 30 day share price return that fell 29.87% and a 90 day share price return that declined 18.66%. The year to date share price return is very large at about 335.67%, and the 1 year total shareholder return of 173.75% contrasts with a 3 year total shareholder return that fell 34.09% and a 5 year total shareholder return that declined 54.70%. This signals strong recent momentum set against a weaker longer term record.
Compare Soitec's sharp swing in returns with other chipmakers by scanning the 53 AI infrastructure stocks that are tightly linked to data centers and AI hardware demand.
Soitec’s surge this year sits awkwardly against its weaker multi year record, which leaves a simple puzzle. Has the business really changed that quickly, or has sentiment just swung too far?
Most Popular Narrative: 34% Undervalued
On the analyst consensus Narrative on Simply Wall St, Soitec’s fair value of €164.79 sits well above the last close of €108.35. This puts the recent share rebound in a different light when set against the analysts’ long run cash flow assumptions and discount rate of 11.75%.
The ongoing large-scale transition to AI, data center expansion and proliferating connected devices is now feeding directly into Soitec’s Photonics-SOI platform. This platform has already reached more than $100m of revenue with growth above 30% year on year and guidance for revenue to more than double again in FY27. This points to a growing contribution to group revenue and potentially higher margin mix.
See why 25 investors see Soitec as 34% undervalued.
Result: Fair Value of €164.79 (UNDERVALUED)
Still, Soitec’s RF-SOI inventory overhang and the tax settlement that removes roughly €320m of loss carry forwards could easily disrupt that upbeat cash flow story.

Another View: What Multiples Say About Soitec
Analyst models currently indicate Soitec as undervalued against a fair value of €164.79, yet the market’s own yardstick tells a different story. On a P/S of 6.5x, the stock trades far above the European semiconductor average of 3.1x, the peer group on 4.1x and even its own fair ratio of 4.1x. That gap highlights valuation risk if sentiment cools or growth expectations slip, so how comfortable are you paying a premium on sales today?
