Soitec (ENXTPA:SOI) is back in focus after first quarter revenue reached €113 million, compared to €92 million a year earlier, alongside fresh guidance and capacity news in its Photonics-SOI business.

See our latest analysis for Soitec.

Soitec’s recent guidance around more than 30% expected year on year revenue growth in the second quarter and the ramp up of its Singapore Photonics SOI capacity has coincided with short term momentum. The 1 day share price return is 5.1% and the 7 day share price return is 10%, while the 90 day share price return is down 25.6% and the 3 year total shareholder return is down 37.7%. This suggests recent enthusiasm is building from a weak longer term base.

Soitec shares now sit about 27% below the average analyst price target after this sharp bounce. Is that a genuine discount, or is the market right to stay cautious given recent share price and earnings volatility?

Most Popular Narrative: 21.3% Undervalued

The most followed narrative currently sees Soitec’s fair value at €138.89, above the last close at €109.30. That gap is built on some punchy growth and margin assumptions that go well beyond the latest quarter.

The ongoing large-scale transition to AI, data center expansion, and proliferating connected devices (including IoT) is driving robust and accelerating demand for advanced substrates like those Soitec produces, supporting long-term revenue visibility and potential 2x revenue opportunity as their addressable market is projected to grow from 5 million wafers in 2024 to 12 million by 2030.
