Published on September 2, 2026 at 22:39 · Updated on September 2, 2026 at 22:39 · by Aurélien Ambert, QDNA

Exchange : Euronext Paris · Sector : Semiconductors FD-SOI / POI / AI

In short

The technical signal is weak, with no directional conviction, mainly because of an early cyclical recovery and a valuation never tested against STMicro or Infineon. The price layer remains silent and export risks weigh on the picture.

Current signal: weak (single draw, outside the three-draw protocol)
Deterministic score: –

Thesis

The cyclical turnaround is real on fundamentals, with a cleaned-up balance sheet and an AI growth relay in photonics-SOI. The price layer remains silent and the risk layer carries an unquantified geopolitical over-risk. The idea is justified only after a catalyst, never as a single block.

Bull case

Sequential growth exceeds more than 25 % in Q4'26, above guidance, and Q1 FY27 is expected at more than 15 %. The photonics-SOI segment exceeds 100 M USD, net debt to EBITDA stands at 0.4x and cash flows have turned positive again. Execution tracks the promise.

Bear case

FY26 revenue declines by 34 %. The cyclical recovery remains young and is not confirmed by stock flows. The valuation has never been verified against STMicro or Infineon. SOI substrates remain exposed to the grey zone of export controls toward China. A new trade shock would erase the recovery premium.

Scenarios

Bull scenario at 30 %, with a cyclical recovery confirmed in Q2 and Q3 FY27, an EBITDA margin near 30 %, with no verifiable quantified target. Central scenario at 45 %, built on single-digit growth and a price range around 108 EUR. Bear scenario at 25 %, on guidance revision or tariff friction, with a maximum loss of 40 to 50 %.

Risks

Export controls toward China on SOI substrates represent an unquantified geopolitical risk. A guidance revision or a new tariff friction could erase the recovery premium. The valuation is not supported by a robust comparison with STMicro or Infineon.

Frequently asked questions

What does a WEAK signal mean on this stock?

A WEAK signal reflects the absence of directional conviction from the system. The cyclical turnaround is real on fundamentals, but the price layer remains silent and the valuation is not tested against STMicro or Infineon. The cyclical recovery is young and export risks toward China weigh on visibility.

Why is the sequential growth of Q4'26 highlighted?

Q4'26 shows sequential growth of more than 25 %, above guidance. Q1 FY27 is expected at more than 15 % and the photonics-SOI segment exceeds 100 M USD. The balance sheet has been cleaned up, with net debt to EBITDA at 0.4x and cash flows back in positive territory.

What are the main risks identified?

SOI substrates remain exposed to the grey zone of export controls toward China, which represents an unquantified geopolitical risk. FY26 revenue declines by 34 %, a sign of an early cyclical recovery. A new trade shock could erase the recovery premium.

What does the central scenario project?

The central scenario, weighted at 45 %, assumes single-digit growth and a price range around 108 EUR. It assumes the absence of a major negative catalyst such as a guidance revision. It sits between the bull scenario at 30 % and the bear scenario at 25 %.

What would happen in the bear scenario?

The bear scenario, weighted at 25 %, rests on a guidance revision or tariff friction. It envisages a maximum loss of 40 to 50 %. This level reflects the stock's sensitivity to export controls and to the fragility of the cyclical recovery, still unconfirmed by flows.
