Soitec (ENXTPA:SOI) Could Be 57% Below Fair Value Following AI Spending Questions
Recent commentary around Soitec (ENXTPA:SOI) is zeroing in on one issue. Investors are questioning how sustainable AI infrastructure spending really is, and whether that supports the company’s current premium price-to-sales valuation.
Over the past year, Soitec’s share price has surged, with a year-to-date share price return of about 395% and a 1-year total shareholder return of 197%, even though the 30-day share price return is down 13.64% and longer term 3 and 5-year total shareholder returns remain negative. Recent weakness over the past month sits alongside a 17.86% 90-day share price gain, which suggests momentum has cooled in the short term as investors reassess how much premium they want to pay for AI exposed revenue while the stock trades around €123.10.

After a move this steep, either Soitec’s rally has already banked most of the AI enthusiasm, or investors are still underestimating what they are paying for each euro of sales.
Most Popular Narrative: 57% Undervalued
Against Soitec’s last close of €123.10, the most followed narrative anchors on a fair value of €284.86, which frames today’s price as heavily discounted once optimistic AI and photonics assumptions are incorporated using an 11.68% discount rate.
Acceleration in Soitec's Photonics-SOI activity, with revenue already above $100m, growth above 30% in the most recent full year and an expectation for FY27 revenue to more than double again, points to a larger AI data center optical interconnect business than most models currently assume. This could add meaningful upside to revenue and operating leverage if multi year customer commitments continue to ramp.
See why 6 investors see Soitec as 57% undervalued.
Result: Fair Value of €284.86 (UNDERVALUED)
Still, the bullish Soitec narrative hinges on mobile and automotive demand stabilising, and on new platforms avoiding further impairments after the SmartSiC reset.
